Description

Technical Field

[0001] This utility model belongs to the field of textile equipment technology, and in particular relates to a textile fabric cutting anti-shrinkage positioning mechanism. Background Technology

[0002] The final step in textile fabric processing involves winding the fabric onto rollers. After each roller is wound, the fabric is cut and then wound onto the next roller. Because textile fabrics are elastic, they spring back after being cut, requiring operators to manually pull them out from the drive rollers of the winding machine. Even after the fabric has completely retracted into the drive rollers, tools are needed to pull the retracted end of the fabric outwards, resulting in inefficient and cumbersome winding operations. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide an anti-retraction positioning mechanism that can clamp and fix textile fabric while cutting it.

[0004] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: a textile fabric cutting anti-shrinkage positioning mechanism, including a machine frame, a cutting mechanism, a platform, a support, and a clamping mechanism. The cutting mechanism and the platform are both mounted on the machine frame. The left side of the platform surface is provided with a groove that cooperates with the cutter of the cutting mechanism. The support is fixedly mounted on the cutting mechanism, and a pressure head is fixedly mounted on the support. A slot is provided on the right side of the platform surface. The clamping mechanism consists of a first clamping block, a second clamping block, guide rods, and springs. The first clamping block is fixedly mounted on the left end of the slot. Four guide rods distributed in a rectangular pattern are slidably mounted on the right end of the slot. The second clamping block is fixedly mounted on the left end of the guide rods. Springs are sleeved on the guide rods. The left and right ends of the springs act on the right end face of the second clamping block and the right side wall of the slot, respectively. The front and rear ends of the clamping faces of the first and second clamping blocks are both set with a first bevel structure. The front and rear ends of the pressure head are set with a second bevel structure that cooperates with the first bevel structure.

[0005] Preferably, rubber pads are fixedly affixed to the clamping surfaces of the first clamping block and the second clamping block, and ball bearings are embedded in the left and right sides of the pressure head.

[0006] Preferably, 5-10 sets of clamping mechanisms are provided along the length of the platform.

[0007] Preferably, the longitudinal section of the groove is configured as a V-shaped structure.

[0008] Compared with the prior art, the advantages of this utility model are: when changing the roller to cut the textile fabric, the textile fabric is pressed into the first clamping block and the second clamping block by the pressure head, and the textile fabric is pressed and fixed by the spring to prevent it from springing back. This solves the problem that the operator needs to manually pull the end of the textile fabric out of the drive roller of the winding equipment after the textile fabric springs back, thus improving the efficiency of the winding operation.

[0013] The present invention will now be described in detail with reference to specific embodiments:

[0014] like Figures 1 to 3 The illustrated textile fabric cutting anti-shrinkage positioning mechanism includes a machine frame 1, a cutting mechanism 2, a platform 3, a support 4, and a clamping mechanism. The cutting mechanism 2 and the platform 3 are both mounted on the machine frame 1. The left side of the platform 3 has a groove 31 that mates with the cutter 21 of the cutting mechanism 2. The support 4 is fixedly mounted on the cutting mechanism 2, and a pressure head 41 is fixedly mounted on the support 4. A slot is provided on the right side of the platform 3. The clamping mechanism consists of a first clamping block 51, a second clamping block 52, a guide rod 6, and a spring 7. The first clamping block 51 is fixedly mounted on the left end of the slot. Four rectangular guide rods 6 are slidably installed on the right end of the card slot. A second clamping block 52 is fixedly installed on the left end of the guide rods 6. A spring 7 is sleeved on the guide rods 6. The left and right ends of the spring 7 act on the right end face of the second clamping block 52 and the right side wall of the card slot, respectively. The front and rear ends of the clamping faces of the first clamping block 51 and the second clamping block 52 are both set as first oblique angle structures. The front and rear ends of the pressure head 41 are set as second oblique angle structures that cooperate with the first oblique angle structures. The second oblique angle structure cooperates with the first oblique angle structure to play a guiding role, so that the first clamping block 51 and the second clamping block 52 separate to create a gap 50.

[0015] Rubber pads are fixedly attached to the clamping surfaces of the first clamping block 51 and the second clamping block 52. The rubber pads can increase the friction between the rubber pads and the textile fabric, preventing the textile fabric from coming out of the clamping surfaces of the first clamping block 51 and the second clamping block 52. Ball bearings 53 are embedded in the left and right sides of the pressure head 41. The rolling of the ball bearings 53 can prevent the blockage caused by the sliding friction between the left and right sides of the pressure head 41 and the rubber pads.

[0016] The clamping mechanism is arranged in 8 groups along the length of the platform 3, that is, each group of clamping mechanisms clamps the textile fabric separately. There is a gap of 5-10mm between the second clamping blocks 52 of each group of clamping mechanisms to avoid mutual interference between the second clamping blocks 52 of each group of clamping mechanisms. The dimensions of the first clamping block 51 and the second clamping block 52 of a single clamping mechanism along the length of the platform 3 are set to 30-50mm to prevent the textile fabric from shrinking before it is clamped and fixed due to excessive length of the first clamping block 51 and the second clamping block 52.

[0017] The longitudinal section of the groove 31 is set as a V-shaped structure, which has the advantage of facilitating the cleaning of textile fabric cutting debris.

[0018] The cutting mechanism 2 is an electrically powered mobile cutting mechanism. After a single roller is wound up, the textile fabric is attached to the platform 3 and pulled to the left. After the textile fabric exceeds the groove 31, the cutting mechanism 2 is activated and moves along the length of the platform 3. The cutter 21 cuts the textile fabric. The pressure head 41 is in the same longitudinal plane area as the cutter 21. The pressure head 41 moves synchronously with the cutting mechanism 2. The pressure head 41 presses the textile fabric into the gap 50 between the first clamping block 51 and the second clamping block 52. After the pressure head 41 leaves the clamping area between the first clamping block 51 and the second clamping block 52, the second clamping block 52 moves to the left and resets under the action of the spring 7. The textile fabric is clamped and fixed between the first clamping block 51 and the second clamping block 52. After the operator replaces the next roller, the textile fabric can be pulled out from between the first clamping block 51 and the second clamping block 52.
