Description

a tearing machine

【Technical field】

The utility model relates to the field of mechanical manufacturing, in particular to a cloth tearing machine.

【Background technique】

The tension control part structure of the existing machine relies on the weight of the weight to pull the tension adjustment roller to change the tension of the feed material. Since the raw material roller adopts a cylinder action damping mechanism, the speed of the raw material roller will automatically increase when the tension increases, thereby improving On the contrary, the pulling force decreases, the speed of the raw material drum decreases, and the feeding speed becomes slower; the cloth tearing method uses a cutter to cut the cloth, and often cuts the warp of the raw material; the finished product coiling part (rocking arm ) is complex in structure, the take-up roller is driven by a synchronous belt, which is often damaged, and the synchronization effect is poor; roll;

The deficiencies or shortcoming that these prior art exist are:

(1) The structure of the tension control part of the machine is cumbersome, which increases the manufacturing cost, and after transformation, this device can be omitted;

(2) It is easy to cut off the warp thread of the raw material by cutting the cloth with a cutter, resulting in defective products;

(3) The complex rocker arm is not only difficult to manufacture, but also troublesome to install and maintain, and the synchronization effect is not good. The production is often affected by the damage of the synchronous belt and synchronous wheel, and the failure rate is high;

(4) It is not only labor-intensive to decide when to change the coil to take the finished product by manual observation, but also the diameter of the finished product rolls taken out is different, which reduces the uniformity of the product, and at the same time, it is easy to break down after the finished machine is rolled .

【Content of utility model】

The purpose of the utility model is to overcome the deficiencies of the prior art and provide a cloth tearing machine.

The purpose of this utility model is achieved through the following technical solutions:

A cloth tearing machine, comprising a coiling forming device and a photoelectric detector; it is characterized in that, the power roller in the coiling forming device is connected to the motor of the coiling forming device through a chain;

The photoelectric detector is arranged on the frame above the finished product take-up wheel;

The finished product coiling wheel of the utility model has no power, and only when the coiler is placed on the power rod to work, it is driven by the friction force between the finished product coiled on it and the power rod, and it rotates passively. Take the finished product, the tearing machine has no power shaft (replaced by a non-rotating stationary shaft, because there is no need to provide power for the clutch, large synchronous wheel, etc.), when the machine is running, the motor of the coiling and forming device , through the chain to drive the power roll to rotate; the finished product is manually pre-rolled one or two times on the finished product take-up wheel through the first-running process at the beginning of the machine, and then directly placed on the power roll, under the action of the self-weight of the take-up device. The friction between the finished product on the take-up wheel and the power shaft drives the take-up wheel to rotate to complete the take-up of the finished product;

One end of the photoelectric detector of the utility model emits light, the other end receives light, and has no mechanical connection with the coiling and forming device; at the beginning, there are fewer finished products on the finished coiling wheel, and its radius is small, so the optical path of the photoelectric detection device can directly When the radius of the finished product on the finished take-up wheel gradually increases to a certain extent with the progress of production, it blocks the optical path of the photoelectric detection device, and at this time the photoelectric detection device immediately sends a stop signal to command the machine to stop and pass The sound and light alarm signal reminds the staff on duty to take away the finished product.

Compared with prior art, the positive effect of the utility model is:

(1) The coordination and cooperation ability of each part function of the present utility model has been strengthened, and the maximum operating speed of the machine has increased to 20 meters/minute from original 12 meters/minute;

(2) The cloth tearing machine manufactured by the utility model not only has the characteristics of high degree of automation, scientific and reasonable structure, convenient use, low failure rate, and low operating cost, but also greatly improves the operating speed of the whole machine and improves production efficiency. Moreover, the manufacturing cost is greatly reduced, and considerable economic benefits are brought to the enterprise.

The schematic diagram of the photodetector in Fig. 2 the utility model;

The labels in the accompanying drawings are respectively: 1. power roller, 2. finished product coiling wheel, 3. finished product coiling device, 4. photoelectric detection device.

【Detailed ways】

Further description will be made below in conjunction with the accompanying drawings.

Please refer to accompanying drawings 1 and 2, a kind of cloth tearing machine, comprises coiling and forming device 3 and photoelectric detector 4; The power roller 1 in the described coiling and forming device is connected with the electric motor of coiling and forming part by chain ;

The photoelectric detector 4 is arranged on the frame above the finished product take-up wheel 2;

The pneumatic tension brake is arranged at the raw material supply drum, and the Korean pneumatic tension brake is used to replace the tension adjustment device in the prior art with DP, and the weight tension adjustment device is omitted; the pressure of the intake air is properly adjusted through the pressure reducing valve The damping force of the feeding roller can be flexibly adjusted according to the size, so that the feeding speed can automatically track the speed of the machine. After the improvement, the structure of the equipment is simplified, the cost of the equipment is reduced, and the operating performance of the system is improved;

The finished product coiling wheel of the utility model has no power, and only when the coiler is placed on the power rod to work, it is driven by the friction force between the finished product coiled on it and the power rod, and it rotates passively. Take the finished product, the tearing machine has no power shaft (replaced by a non-rotating stationary shaft, because there is no need to provide power for the clutch, large synchronous wheel, etc.), when the machine is running, the motor of the coiling and forming device , through the chain to drive the power roll to rotate; the finished product is manually pre-rolled one or two times on the finished product take-up wheel through the first-running process at the beginning of the machine, and then directly placed on the power roll, under the action of the self-weight of the take-up device. The friction between the finished product on the take-up wheel and the power shaft drives the take-up wheel to rotate to complete the take-up of the finished product;

One end of the photoelectric detector emits light, and the other end receives light, and there is no mechanical connection with the coiling and forming device; at the beginning, there are fewer finished products on the finished coiling wheel, and its radius is small, so the optical path of the photoelectric detection device can directly shoot; when the finished product When the radius of the finished product on the take-up wheel gradually increases to a certain extent as the production progresses, it blocks the optical path of the photoelectric detection device. Remind the staff on duty to take away the finished product.
