Description

Knitting action parts structure

The present invention provides a knitting action component structure, which includes a channel space and its related components: a needle plate assembly, a corner assembly, and a knitting tool structure.

Common knitting machines, such as circular knitting machines and flat knitting machines, have a knitting action that drives the guide protrusions on the knitting tools along the guide grooves in the corners, moving back and forth in the guide groove area, so that the knitting tools configured in the needle plate assembly move synchronously, and the interaction causes the yarns to be interwoven to produce fabrics.

Among the many defects caused by knitting, taking circular knitting machines as an example, the high temperature affecting the life and precision of related accessories and the contamination of fabrics by oil (such as grease and cotton wool) have always been two major problems that related companies in the industry want to solve. WO2020079493A1 discloses many types of fabric defects, such as oil pollution defects, knitting needle and sinker defects, and other pollution defects.

TWI303284B reveals that the pressurized gas is powerfully ejected through multiple nozzles and blown toward the needle cylinder, needle groove, weaving needle and corner assembly to achieve the effect of removing lint and dissipating heat.

EP2067885B1 discloses a modular needle bed with a fluid channel that can remove accumulated dirt and prevent excessive lubricant from contaminating the fabric.

JP20008258A discloses that by setting a surrounding cover plate on the outside of the corner assembly, external cotton dust can be prevented from entering the knitting action part, and a cooling effect can be achieved by operating a blower.

CN108026676B discloses a loop forming method, device and system components, which place a pair of knitting tools in a groove of a needle plate assembly with a wider width than the conventional design, and utilize the time difference in the operation of the two adjacent knitting tools or add a material with very low friction and/or self-lubricating properties, such as graphite or Teflon, as a spacer for the pair of knitting tools to achieve self-cleaning and heat dissipation effects.

The aforementioned technologies reduce pollution and heat dissipation by increasing operating equipment or more complex production processes, but at the same time increase costs and energy loads.

EP3947799B1 discloses the shape design of another part of the knitting tool, which removes the dirt in the groove near the loop forming part to the inner edge of the needle bed, and the height of the knitting tool part is equal to the height of the needle plate assembly part; JP2022085768A discloses a double sinker structure, and the height of the knitting tool part is greater than the height of the needle plate assembly part.

TWI639742B discloses that the surface extending from the front top end to the rear top end of the needle plate assembly part is parallel to the reference bottom surface on the other side as the height reference line. WO2022128297A1 discloses that the knitting tool part and the corner assembly part are parallel to each other in the top and bottom surfaces, and each has a conventional design with the same height at the front and rear ends; EP4095297A1 discloses that the corner assembly part of the conventional design is parallel to the needle plate assembly part and the knitting tool part, forming a channel space part with parallel sides.

Based on fabric quality requirements and production capacity needs, and taking into account the physical properties of thermal expansion, the current conventional design of the channel space is about 0.20 mm in height, and the high temperature caused by the inertia of knitting movements also accumulates continuously in this narrow space.

CN1974903A discloses that the normal gap in the channel space is reduced to almost zero, and pressurized air is injected into the space to achieve cleaning and cooling effects.

CN201678816U discloses that the lubricating oil channel in the conventionally designed corner guide groove can also be used as an air channel, and the air is ejected and released from there to achieve the heat dissipation effect of the channel space and its related components.

The aforementioned technology of injecting compressed air into the channel space not only requires additional energy consumption, but also easily causes the related components to bring splashing oil into the fabric.

JP4454634B2 discloses the contact points and surfaces of the knitting tool parts in the needle plate assembly parts due to the inertia of movement and frictional heat generation.

When the lubricating oil is released from the guide groove of the corner, due to the conventional design of the needle plate assembly with the same height at the front and rear ends and the inertia of the knitting action, the knitting tool rubs parallel to the surface of the needle plate, or its convex piece rubs vertically on the side corner of the needle plate, causing the lubricating oil to flow back and forth on the surface of those parts after being drawn, and accumulates repeatedly and is accompanied by other contaminants such as worn fibers moving along the knitting tool part to the looping part, causing the fabric to be contaminated.

TWI560331B reveals the path of the lubricating oil after it is released and improves the shape design of knitting tools to block the oil pollution from moving to the loop forming area.

This invention proposes a knitting motion component structure based on the aforementioned technology, conventional design and knitting motion inertia: when manufacturing related components, no additional equipment or more complicated processing procedures are required to improve product quality; when using a knitting machine to produce fabrics, no additional energy-consuming device is required to prevent oil stains, cotton wool and oil pollution from contaminating the fabric and optimize heat dissipation performance, avoid waste caused by defective products and extend the service life of related accessories.

In order to achieve the above-mentioned objectives, the present invention provides a knitting action component structure, which includes a channel space and related components; a needle plate assembly, a corner assembly, and a knitting tool structure. The knitting tool is placed in the needle plate assembly, facing the corner assembly to form a channel space; wherein, at least one space portion is composed of a corner assembly portion facing a needle plate assembly portion and a knitting tool portion, and these portions are bounded by the front end close to the loop forming portion and the rear end far from the loop forming portion. Except for the corner guide groove area and the guide plate area of the knitting tool and the highest and lowest height portions, the channel space portion from the front end to the rear end of the portion forms a gradually expanding space with non-parallel sides, and the height difference is more than 0.06 mm.

In the following embodiments, the front end height of at least one relevant component part is not equal to the rear end height, so that the front end to the rear end of both sides of the channel space part are not parallel.

In the first embodiment, a needle plate assembly part of the present invention, a corner assembly part and a knitting tool part are combined to form a channel space part, which can increase the resistance of the oil pollution path, making it more difficult for the oil pollution to move to the looping part, and achieve better air diversion and heat dissipation effects with the gradually expanded space.

In the second embodiment, a corner assembly of the present invention, a needle plate assembly and a knitting tool assembly are combined to form a channel space, which can reduce obstacles for the oil pollution path, making it easier for the oil pollution to move downward away from the looping area, and achieve better air diversion and heat dissipation effects with the gradually expanding space.

In the third embodiment, a knitting tool part of the present invention, a needle plate assembly part and a corner assembly part are formed into a channel space part, which can increase the power of the oil pollution path, making it easier for the oil pollution to move away from the looping place, and achieve better air diversion and heat dissipation effects with the gradually expanded space.

In the fourth embodiment, each channel space is composed of the knitting motion component structure of the present invention in the aforementioned embodiments. In addition to a more significant self-cleaning effect, the larger gradually expanding spaces will enable the better air flow and heat dissipation effects of the aforementioned embodiments to be more significant.

The knitting tool 4 in FIG1 and FIG3 is understood to move horizontally on the ground, and in FIG2 is understood to move vertically on the ground. Each part is defined as the front end close to the loop forming part and the rear end far from the loop forming part.

FIG1 shows a cross-sectional view of the first embodiment, which shows, from top to bottom, the conventional knitting tool 4, the conventional corner assembly 3, the needle plate assembly 2 of the present invention, and the channel space 1 formed therefrom. During the knitting operation, when the front edge 4A of the tool is flush with the front edge 2A of the assembly, the guide plate area 43 is relatively close to the rear end 332 of the guide groove area rather than the front end 331.

FIG2 shows a cross-sectional view of the second embodiment, which shows, from top to bottom and from left to right, the conventional knitting tool 4, the corner assembly 3 of the present invention, the conventional needle plate assembly 2, and the channel space 1 formed therefrom. During the knitting operation, when the front edge 4A of the tool is flush with the front edge 2A of the assembly, the guide plate area 43 is relatively close to the rear end 332 of the guide groove area rather than the front end 331.

FIG3 shows a cross-sectional view of the third embodiment, which shows, from top to bottom, the knitting tool 4 of the present invention, the known mountain corner assembly 3, the known needle plate assembly 2, and the channel space 1 formed therefrom. During the knitting operation, when the front edge 4A of the tool is flush with the front edge 2B of another assembly, its guide plate area 43 is relatively close to the rear end 332 of the guide groove area rather than the front end.

FIG4 shows a schematic diagram of the fourth embodiment, which sequentially replaces the known knitting motion component structure and the channel space 1 composed of the knitting motion component structure of the present invention in the above-mentioned figures from top to bottom and from left to right. During the knitting operation, when the knitting tool 4 moves from back to front so that its front end 4A is far away from the assembly front edge 2A or another assembly front edge 2B, its guide plate area 43 is relatively close to the front end 331 of the guide groove area rather than the rear end 332.

The first embodiment shown in FIG. 1 is a space part 10 composed of the assembly part 20 of the present invention, the known assembly part 30 and the tool part 40.

The knitting tool 4 is a knitting needle having two guide areas 43, which correspond to two corner guide groove areas 33 respectively, and the tool part 40 also covers a maximum height H4 and a minimum height H40. It is known that the front end height H41 of the tool part is equal to the rear end height 42. Except for the maximum height H4, the minimum height H40 and the guide area 43, the surface extending from the front top 41 to the rear top 42 is parallel to the other side of the reference bottom surface 401.

The corner assembly 3 is composed of a slider 35 connecting a corner 34 and a corner seat 36. The front top 31 and the rear top 32 of the assembly part 30 composed of the two corners 34 correspond to the front top 21 and the rear top 22 of the assembly part 20 respectively. It is known that the front end height H31 and the rear end height H32 of the part are equal, and the surface extending from the front top 31 to the rear top 32 is parallel to the reference bottom surface 301 on the other side.

In the needle plate assembly 2, the needle plate 23 uses the insert structure of the invention patent TWI639742B. After assembly, it has a uniform outer surface without the need for grinding. The front end height H21 of the part 20 is not equal to the rear end height H22. The surface extending from the front top end 21 to the rear top end 22 is not parallel to the other side reference bottom surface 201. The preferred height difference is 0.08 mm. The height difference can be achieved by designing the shape of the needle plate 23 and conventional manufacturing (for example, punching machine processing), or by designing the height difference between the front abutment surface 231 and the rear abutment surface 232 of the needle plate and conventional manufacturing (for example, lathe processing).

As in the above conditions, during the knitting process, when the front edge 4A of the tool is flush with the front edge 2A of the assembly, the guide plate area 43 is relatively close to the rear end 332 of the guide groove area; if the front end height H11 of the space part 10 is equal to 0.20 mm of the normal height H10, then the rear end height H12 is 0.28 mm, which means that the front end 11 to the rear end 12 of the space part is a gradually expanding space with non-parallel sides, and the height difference (H12 minus H11) is 0.08 mm.

During the knitting process, the inclined surface of the needle plate assembly 20 can increase the forward resistance of the oil dirt path, making it more difficult for the oil dirt to form a loop. And the inertial friction of the knitting action can increase the backward force of the oil dirt path, bringing the oil dirt to the lower part of the surface more smoothly, making it easier for the oil dirt to stay away from the loop. The pressure difference formed by the height difference at both ends of the gradually expanding space can make the air diversion more significant and achieve a better heat dissipation effect.

The second embodiment shown in FIG. 2 is a channel space portion 10 composed of the corner assembly portion 30 of the present invention, the needle plate assembly portion 20 and the knitting tool portion 40 known in the art.

The knitting tool 4 is a knitting needle having four guide areas 43, which correspond to four corner guide groove areas 33 respectively, and the tool part 40 also covers a maximum height H4 and a minimum height H40. It is known that the front end height H41 of the tool part is equal to the rear end height 42. Except for the maximum height H4, the minimum height H40 and the guide area 43, the surface extending from the front top end 41 to the rear top end 42 is parallel to the reference bottom surface 401 on the other side.

In the needle plate assembly 2, the needle plate 23 is a known insert, which must be polished after assembly to obtain a uniform outer surface. The front end height H21 of the assembly part 20 is equal to the rear end height H22, and the surface extending from the front top end 21 to the rear top end 22 is parallel to the reference bottom surface 201 on the other side.

The corner assembly 3 can be manufactured according to conventional methods, that is, the corner 34 is locked on the corner seat 36, or a slider 35 is inserted into the corner seat slider groove 360 on one side and the corner slider groove 340 on the other side to lock the corner 34, so that the assembly part 30 as a whole is easier to adjust and move.

In this embodiment, the front end 31 and the rear end 32 of the assembly part 30 are composed of four corners 34, which correspond to the front top end 21 and the rear top end 22 of the assembly part 20 respectively. The front end height H31 of the part 30 is not equal to the rear end height H32, and the surface extending from the front top end 31 to the rear top end 32 is not parallel to the other side of the reference bottom surface 301, and the preferred height difference is 0.10 mm. The height difference is designed to correspond to the height difference of each corner 34 in a stepped manner from the front end height H351 of the slider 35 to the rear end height H352, and can be achieved by conventional manufacturing (for example: powder metallurgy).

As in the above conditions, during the knitting process, when the front edge 4A of the tool is flush with the front edge 2A of the assembly, the guide plate area 43 is relatively close to the rear end 332 of the guide groove area; if the front end height H11 of the space part 10 is equal to 0.20 mm of the normal height H10, then the rear end height H12 is 0.30 mm, which means that the front end 11 to the rear end 12 of the space part is a gradually expanding space with non-parallel sides, and the height difference (H12 minus H11) is 0.10 mm.

During the knitting process of this component structure, the stepped height difference of the corner assembly part 30 can reduce obstacles for the oil pollution path, so that when the oil pollution moves downward, it is not easy to adhere to and accumulate on the corner 34 below. The pressure difference formed by the height difference at both ends of the gradually expanding space part can make the air diversion more significant and achieve a better heat dissipation effect.

The third embodiment shown in FIG. 3 is a channel space portion 10 composed of the knitting tool portion 40 of the present invention, the conventional needle plate assembly portion 20 and the corner assembly portion 30.

The knitting tool 4 is a sinker with a guide plate area 43 corresponding to a corner guide groove area 33, and the tool part 40 also covers a maximum height H4 and a minimum height H40. The front end height H41 of the tool part is not equal to the rear end height 42. Except for the maximum height H4, the minimum height H40 and the guide plate area 43, the surface extending from the front top 41 to the rear top 42 is not parallel to the other side of the reference bottom surface 401, and the preferred height difference is 0.06 mm. The height difference can be achieved by the shape design of the knitting tool 4 and conventional manufacturing (for example: punching machine processing).

The needle plate assembly 2 is formed by lathe processing and then grooves are cut to form the needle plate 23. The front end height H21 of the assembly part 20 is equal to the rear end height H22, and the surface extending from the front top end 21 to the rear top end 22 is parallel to the other side reference bottom surface 201.

The corner assembly 3 is composed of a corner 34 directly locked on a corner seat 36, and the front top 31 and rear top 32 of the part 30 correspond to the front top 21 and rear top 22 of the assembly part 20 respectively. It is known that the front end height H31 and the rear end height H32 of the part are equal, and the surface extending from the front top 31 to the rear top 32 is parallel to the reference bottom surface 301 on the other side.

As in the above conditions, during the knitting process, when the front edge 4A of the knitting tool is flush with the front edge 2B of the other needle plate assembly, its guide plate area 43 is relatively close to the rear end 332 of the guide groove area; if the front end height H11 of the channel space part 10 is equal to 0.20 mm of the normal height H10, then its rear end height H12 is 0.26 mm, which means that the front end 11 to the rear end 12 of the space part is a gradually expanding space with non-parallel sides, and its height difference (H12 minus H11) is 0.06 mm.

During the knitting process, the inclined surface of the knitting tool part 40 of this component structure can increase the forward resistance of the oil and dirt path, making it more difficult for the oil and dirt to approach the loop. Through the inertial friction of the knitting action, the oil and dirt path can be increased to move backward, and the oil and dirt are brought to the lower part of the surface, making it easier for the oil and dirt to stay away from the loop. The pressure difference formed by the height difference at both ends of the gradually expanding space part can make the air diversion more significant and achieve a better heat dissipation effect.

The fourth embodiment shown in FIG. 4 is a method of changing the known structure in the aforementioned embodiments into the knitting action component structure of the present invention and forming each channel space portion 10.

As in the above conditions, during the knitting process, when the knitting tool 4 moves from the back to the front so that its front edge 4A is far away from the front edge 2A of the needle plate assembly or the front edge 2B of another needle plate assembly, its guide plate area 43 is relatively close to the front end 331 of the guide groove area, and the tool part 40 also moves relatively; if the front end height H11 of the channel space part 10 is equal to 0.20 mm of the conventional height H10, then its rear end height H12 varies from 0.26 mm to 0.38 mm in different embodiments, which means that the front end 11 to the rear end 12 of the space part is a gradually expanding space with non-parallel sides, and the height difference (H12 minus H11) varies from 0.06 mm to 0.18 mm.

Compared with the above three embodiments, in this component structure, during the knitting process, the inclined surfaces of the needle plate assembly parts 20 and the knitting tool parts 40 can not only optimize the resistance of the oil pollution path to the loop and the assistance away from the loop, but also accelerate the removal of oil pollution through the inertial friction of the knitting action to achieve a self-cleaning effect; and can form a gradually expanding space with a larger pressure difference with the corner assembly part 30, which can make the significant air diversion more significant and the optimized heat dissipation effect more optimized.

The above description is based on the common processing diagram method in the relevant technical field, and after understanding the above preferred embodiments, people with ordinary knowledge can make changes and modifications based on the technology taught by the present invention, which does not deviate from the spirit and scope of the present invention.
