Description

A fiber fineness strength and elongation tester

Technical Field

The present application relates to the technical field of fiber testing, and in particular to a fiber fineness strength and elongation tester.

Background Art

The fineness tensile tester is an instrument used to test the strength and ductility of materials under a certain load. It is commonly used in the quality control and research fields of textiles, plastics, rubber and other materials. By applying a certain tensile force, performance indicators such as tensile strength and elongation at break of the material can be measured to evaluate the quality and usability of the material.

In the process of testing the fineness and strength of fibers, usually multiple fiber samples of a certain length are cut from the raw materials to ensure that the fiber length meets the requirements. The samples are then tensioned and fixed on the fixture of the testing device to ensure that the stretching direction is consistent with the movement direction of the measuring device. Finally, data analysis is performed based on the test results.

However, the performance of the fiber may vary at different locations. Therefore, in order to better understand the overall performance of the fiber and provide a more comprehensive and accurate fiber, a longer distance of fiber line is intercepted to conduct multiple strength and elongation tests.

The existing fiber strength testing device usually includes two parts: a fiber fineness testing device and a fiber strength testing device. However, the conventional testing method generally first measures the fiber diameter or cross-sectional area through the fiber fineness testing device to determine the thickness of the fiber, and then moves the fiber to the strength testing device to perform two-step testing on the fiber;

This not only increases the test time and production cost, but also increases the labor intensity of the testers. Therefore, it is necessary to provide a fiber fineness and tensile strength tester to solve the above problems.

It should be noted that the above information disclosed in this background technology section is only for understanding the background technology conceived of the present application, and therefore, it may contain information that does not constitute the prior art.

DETAILED DESCRIPTION

It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this application.

Embodiment 1: As shown in FIG. 12 and FIG. 1 to FIG. 3, the present application provides a fiber fineness strength and elongation tester, including a housing 1 of the tester, wherein a bracket (not shown in the figure) for mounting and supporting a test component is disposed in the housing 1, and a transparent plate 11 is disposed on one side of the housing 1, wherein the transparent plate 11 is hinged to the housing 1, and is suitable for opening or closing the transparent plate 11, so as to facilitate an operator to perform maintenance and adjustment on the test component in the housing 1;

The transparent plate 11 is provided with a slot (not shown in the figure), and a test box 12 is arranged at the slot. The test box 12 is fixedly mounted on a bracket in the shell 1. A strength testing mechanism 2 is arranged in the test box 12, and the strength testing mechanism 2 is used to perform strength testing on the fiber.

A fineness testing mechanism 3 is provided on one side of the test box 12. The fineness testing mechanism 3 is used to test the thickness or cross-sectional area of the fiber. The fineness testing mechanism 3 has a camera 31 provided on a bracket in the housing 1. The camera 31 has artificial intelligence and image recognition technology, which is convenient for identifying and analyzing the fiber morphological characteristics. A sensor is provided on the camera 31, which can be connected to an external computer through the sensor, so that the operator can operate and observe conveniently. The camera 31 is a prior art, and the details can be referred to the relevant patent documents, which will not be described in detail here.

In order to achieve longitudinal position adjustment of the camera 31, a fixing ring 32 is sleeved in the middle position of the camera 31, and a longitudinal adjustment mechanism 33 is installed on the fixing ring 32. The longitudinal adjustment mechanism 33 has a telescopic box 331 fixedly installed on the bracket inside the shell 1. The telescopic box 331 has a telescopic shaft (not marked in the figure), which is slidably connected in the telescopic box 331. The end of the telescopic shaft is fixedly installed on the fixing ring 32, so that the telescopic box 331 can not only support the camera 31, but also make the camera 31 slide longitudinally in the telescopic box 331 through the telescopic shaft;

A connecting plate 332 is fixedly mounted on the telescopic shaft of the telescopic box 331, a connecting block 333 is fixedly mounted on the lower end of the connecting plate 332, a screw 334 is threadedly connected to the connecting block 333, the screw 334 is rotatably connected to the bracket in the housing 1, the screw 334 penetrates the transparent plate 11 and forms a protruding end, and a torsion plate 335 is fixedly mounted on the protruding end of the screw 334, so that the operator can control the screw 334 to rotate outside the housing 1;

At the same time, a sliding bar 336 is provided on one side of the screw rod 334, and the sliding bar 336 is slidably connected to the connecting block 333. The sliding bar 336 can improve the longitudinal movement stability of the connecting block 333. Therefore, when the longitudinal position of the camera 31 needs to be adjusted, the operator rotates the torsion plate 335 outside the shell 1 to rotate the screw rod 334 to drive the connecting block 333 to move longitudinally, and slide on the sliding bar 336 at the same time. When the connecting block 333 slides, it drives the connecting plate 332 and the telescopic shaft to move longitudinally, thereby driving the fixing ring 32 and the camera 31 to move horizontally, thereby completing the longitudinal position adjustment of the camera 31.

In order to adjust the lateral position of the camera 31, a lateral adjustment mechanism 34 is provided on one side of the fixing ring 32. The lateral adjustment mechanism 34 has an external thread 341 opened on the outside of the camera 31. The external thread 341 is located on the inner side of the fixing ring 32. A limit housing 343 is fixedly installed on one side of the fixing ring 32. The limit housing 343 is fixedly installed on the transparent plate 11.

In addition, a rotating shaft 342 threadedly connected to the external thread 341 is provided in the limiting shell 343, and the lateral movement range of the rotating shaft 342 is limited by the limiting shell 343. At the same time, openings (not marked in the figure) are provided on the limiting shell 343 and the transparent plate 11, and the openings are suitable for the operator to control and rotate the rotating shaft 342 outside the shell 1. Therefore, the operator can manually rotate the rotating shaft 342 from the outside so that the camera 31 can be adjusted in the lateral position through the cooperation between the external thread 341 and the thread of the rotating shaft 342, thereby facilitating the control of the position of the camera 31 to adapt to limit lines of different diameters and positions.

As shown in FIG. 2 and FIG. 4-FIG. 5, the strength testing mechanism 2 has a first clamping block 21, and a sliding groove (not shown in the figure) is provided in the test box 12. The first clamping block 21 is fixed to the upper end of the sliding groove, and the first clamping block 21 is located above the camera 31. A second clamping block 22 is provided below the first clamping block 21, and the second clamping block 22 is slidably connected to the sliding groove on the test box 12. Pneumatic fingers (not shown in the figure) are provided on the opposite surfaces of the first clamping block 21 and the second clamping block 22. The pneumatic fingers are actuators that use compressed air as power to clamp fibers and avoid fiber damage. The pneumatic fingers are conventional means in the art and are not described in detail here.

In order to control the position of the second clamping block 22, a driving mechanism 24 is provided at the rear end of the second clamping block 22, and the driving mechanism 24 is suitable for controlling the second clamping block 22 to perform vertical movement. Specifically: in the present application, the driving mechanism 24 has a reduction motor installed on the bracket of the shell 1, and a driving rod is provided on one side of the reduction motor. The driving rod is rotatably connected to the shell 1, and an extension block is installed at the rear end of the second clamping block 22. The extension block is threadedly connected to the driving rod, and a sprocket chain is connected between the output end of the reduction motor and the lower end of the driving rod. Therefore, the reduction motor is started to rotate to drive the driving rod to rotate through the sprocket chain, so that the second clamping block 22 and the extension block perform vertical movement at the same time, and the fiber is pulled for testing;

It should be noted that the driving mechanism 24 can also be configured as a vertically movable mechanism such as a hydraulic cylinder, so the driving mechanism 24 is a conventional means in the art and will not be described in detail here.

At the same time, a reel 23 is fixedly installed at the upper end of the test box 12. The reel 23 is located above the first clamping block 21. The reel 23 is used to reel the fiber to be tested, and the reel 23 is detachable, so that the fiber to be tested can be wound and mounted on the reel 23 conveniently.

In this embodiment, as shown in FIG. 12 , a vacuum adsorption platform is installed at the lower end of the second clamping block 22 , and a wire inlet is provided at the upper end of the vacuum adsorption platform. The vacuum adsorption platform is suitable for adsorbing and straightening the lower end of the fiber to be tensile tested, and collecting the broken wires after being pulled apart.

In summary: when testing the fineness and tensile strength of the fiber, the operator first loads the fiber onto the unwinding roller 23, then pulls the fiber head downward to allow the fiber to pass through the pneumatic fingers on the first clamping block 21 and the second clamping block 22, then uses the vacuum adsorption table to adsorb and straighten the lower end of the fiber, and then clamps the fiber with the pneumatic fingers;

After the fiber is clamped, the operator adjusts the position of the camera 31 through the longitudinal adjustment mechanism 33 and the transverse adjustment mechanism 34, and aligns the lens of the camera 31 with the fiber by observing on the computer, so as to perform the fiber fineness detection operation;

After the fiber fineness is detected, the driving mechanism 24 is then started to control the second clamping block 22 to move downward, and the fiber is stretched until the fiber breaks, thereby testing and detecting the tensile strength and breaking elongation of the fiber in this section;

The broken fibers are collected by a vacuum adsorption table, and then the first clamping block 21 and the second clamping block 22 are opened to cancel the fixation of the fibers. The above operation is repeated to clamp the fibers and perform the second test. Therefore, in the process of testing the fineness and elongation of fibers over a longer distance, there is no need to separate the fibers for two-step testing, thereby reducing the test time, saving production costs, and reducing the labor intensity of testers.

Embodiment 2: In the process of testing the fineness and tensile strength of fibers over a long distance, since the fiber tensile strength test needs to stretch the fibers until they break, the staff is required to frequently manually adjust and locate the broken lines. This method still increases the labor intensity of the testers and it is difficult to realize the characteristics of automation and multifunctionality of the test device. In order to solve the above problems, specifically:

As shown in FIGS. 6 to 10 , a guiding mechanism 4 is provided above the first clamping block 21, and the guiding mechanism 4 is used to guide the broken fiber. The guiding mechanism 4 has a fixing frame 45 fixedly installed on the first clamping block 21, and a sleeve shaft 42 is fixedly installed on the central end of the fixing frame 45, and a fixing plate 431 is fixedly installed on one side of the sleeve shaft 42, and a chuck group 43 is provided at one end of the fixing plate 431 away from the sleeve shaft 42, and the chuck group 43 is used to clamp the fiber, and the chuck group 43 has a first chuck 432 and a second chuck 433, and the contact ends of the first chuck 432 and the second chuck 433 are hinged on the fixing plate 431, so that the first chuck 432 and the second chuck 433 can be opened and closed;

In order to facilitate the operation of opening and closing the chuck group 43, a transmission mechanism 44 is provided above the first clamping block 21. The transmission mechanism 44 has a driving motor 443 fixed on the test box 12. The output shaft of the driving motor 443 is fixed to the upper end of the first clamping block 21 through a bearing seat, and a gear 442 is fixedly installed on the output shaft of the driving motor 443. A rack 441 is meshedly connected to one side of the gear 442, and a movable cylinder 41 is fixedly installed on the other side of the rack 441. The movable cylinder 41 is coaxially arranged with the sleeve shaft 42.

In addition, a steel wire rope 434 is fixedly installed on one end of the first chuck 432 and the second chuck 433 close to the sleeve shaft 42. The other end of the steel wire rope 434 passes through the sleeve shaft 42 and is fixed on the movable cylinder 41. Therefore, the steel wire rope 434 can be pulled by moving the movable cylinder 41, so that the chuck group 43 can be opened and closed.

In order to improve the moving stability of the movable cylinder 41, a slide bar 444 is fixedly installed at the lower end of the movable cylinder 41, and a slide rail 445 is fixedly installed at the upper end of the first clamping block 21. The slide bar 444 and the slide rail 445 are slidably connected. Therefore, by starting the driving motor 443 to drive the gear 442 to rotate, the gear 442 rotates to drive the rack 441 and the movable cylinder 41 to slide linearly in the slide rail 445, so as to open and close the chuck group 43.

A clamping tube 46 is fixedly provided at the axis of the movable cylinder 41, one end of which penetrates between the first clamp 432 and the second clamp 433, and a plurality of wire clamps 47 are placed inside the clamping tube 46, one end of which is provided as an elastic arc ring, and the other end of which has a buckle portion, which can be engaged after being squeezed, so as to clamp the fiber;

It should be noted that when installing the wire clamp 47, its installation direction should be kept horizontal with the clamp group 43, and when the wire clamp 47 is located in the clamp tube 46, it is not engaged at this time, and due to the influence of the elastic arc ring, the wire clamp 47 is horizontally located in the middle of the clamp tube 46, so multiple wire clamps 47 cannot be placed in the clamp tube 46 at the same time.

In this embodiment, a groove 435 is formed inside the first clamp 432 and the second clamp 433 , and the groove 435 is used to place the wire clamp 47 .

As shown in FIGS. 8 and 11 , in order to push the wire clamp 47 in the clamping tube 46 outward, a material pushing member 48 is provided at one end of the clamping tube 46 away from the clamp assembly 43. The material pushing member 48 has a push rod 481. One end of the push rod 481 is located in the clamping tube 46. A push block 483 is fixedly installed at one end of the push rod 481 close to the clamping tube 46. The push block 483 is slidably connected in the clamping tube 46.

In addition, a cylinder 482 is provided at one end of the push rod 481 away from the push block 483. The cylinder 482 is fixed on the bracket inside the shell 1. The output shaft of the cylinder 482 and the push rod 481 are fixedly connected. Therefore, by starting the cylinder 482, the push rod 481 is driven to push the push block 483 toward the chuck group 43, thereby pushing the wire clamp 47 in the clamping tube 46 toward the chuck group 43.

In order to automatically fill the wire clamp 47 in the clamp collecting tube 46, a mounting opening (not shown in the figure) is provided through the end of the clamp collecting tube 46 away from the movable cylinder 41, and a feeding mechanism 5 is provided on the mounting opening. The feeding mechanism 5 has a clamp placing box 51, which is fixed on the test box 12, and the bottom of the clamp placing box 51 is installed on the mounting opening on the clamp collecting tube 46, and the lower end of the clamp placing box 51 is provided with an arc opening flush with the outer wall of the clamp collecting tube 46;

In this embodiment, a plurality of wire clips 47 are also placed inside the clamp box 51 .

At the same time, baffles 52 are installed on both sides of the mounting opening on the clamping tube 46. The bottom end of the baffle 52 is higher than the upper end of the push block 483. It should be noted that the length of the push block 483 is consistent with the length of the wire clamp 47 in the contracted state, and the push block 483 will not separate from the mounting opening of the clamping tube 46 when sliding. At the same time, the upper end of the push block 483 is set to be a plane, so when sliding in the clamping tube 46, it will not be affected by the baffle 52, and when the wire clamp 47 enters the clamping tube 46, it will not be affected by the baffle 52.

A pressing block 54 is slidably connected to the interior of the clamp box 51 . A pull rope 53 is fixedly installed on the upper end of the pressing block 54 . One end of the pull rope 53 away from the pressing block 54 is suspended outside the clamp box 51 .

The bottom of the test box 12 is also fixedly mounted with a collection box 6 .

In this embodiment, the drive motor 443, the cylinder 482 and the pneumatic fingers are all controlled by a PLC program, and a position sensor is provided on the pressing block 54. When a certain position is reached, a reminder will be given on the computer terminal. At this time, the operator stops the test and fills the wire clamps 47 in the clamp box 51.

In summary: before testing the fibers, the driving motor 443 is started to drive the movable cylinder 41 to move laterally toward the cylinder 482, thereby pulling the steel wire rope 434 outward, so that the first clamp 432 and the second clamp 433 are slightly closed;

At the same time, the cylinder 482 is started to push the push rod 481 and the push block 483 to slide in the clamping tube 46 toward the clamp assembly 43, thereby pushing the wire clamp 47 into the clamp assembly 43, so that the wire clamp 47 is located in the groove 435 of the first clamp 432 and the second clamp 433;

Then the cylinder 482 shrinks and resets until it leaves the installation opening of the clamping tube 46. At this time, the wire clamps 47 in the clamp box 51 slide downward under the pressure of gravity and the pressure of the pressing block 54, so that the lower wire clamp 47 enters the clamping tube 46, thereby completing the automatic loading. In addition, since the baffles 52 are arranged on both sides, the push rod 481 and the push block 483 will not drive the upper wire clamp 47 to move when pushing the wire clamp 47, ensuring that only one wire clamp 47 is pushed for loading each time.

At the same time, the driving motor 443 is started to rotate in reverse so that the movable cylinder 41 drives the first clamp 432 and the second clamp 433 to open. Since the wire clamp 47 has elastic force and is pressed in the groove 435, it will not slide off.

At this time, the fiber to be tested is passed through the opened wire clamp 47, the pneumatic fingers on the first clamping block 21 and the second clamping block 22, and then the fiber is clamped by the pneumatic fingers;

When the pneumatic fingers have finished clamping the fiber, the driving motor 443 is started again to drive the movable cylinder 41 to slide until the first clamp 432 and the second clamp 433 are completely clamped, so that the wire clamp 47 clamps and clamps the fiber;

Then, the position of the camera 31 is adjusted so that the lens of the camera 31 is aligned with the fiber, and the fiber fineness detection operation is performed;

After the fiber fineness is detected, the driving mechanism 24 is then started to control the second clamping block 22 to move downward, and the fiber is stretched until the fiber breaks, thereby testing and detecting the tensile strength and breaking elongation of the fiber in this section;

When the fiber is broken, the pneumatic fingers on the first clamping block 21 and the second clamping block 22 are opened, and then the driving motor 443 is started to drive the movable cylinder 41 to open the first clamp 432 and the second clamp 433. At this time, the wire clamp 47 clamps the broken wire end and falls downward with gravity, passing through the pneumatic fingers on the first clamping block 21 and the second clamping block 22. Then, the pneumatic fingers are started again to clamp the fiber, and a tensile test is performed;

When the fiber is broken again, the above operation can be repeated, and the broken fiber line and the fallen wire clamp 47 can be collected through the collection box 6, so that the staff does not need to frequently manually adjust and position the broken line, which solves the labor intensity of the testers, reduces the test cost, and realizes the characteristics of automation and multi-functionality of the test device.

The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
