Description

Technical Field

[0001] The utility model relates to the field of production and processing of TPU composite fabrics, in particular to a fabric cutting device. Background Art

[0002] Thermoplastic polyurethane elastomer, or TPU, is a type of polyurethane material that can be plasticized by heating and dissolved by solvents. It has a unique soft and hard segment copolymer structure. Because it has both the elasticity of rubber and the processability of plastic, it is widely used in many fields. Specialized fabric cutting equipment is used in the production and processing of TPU composite fabrics, such as the Chinese utility model patent with application number CN201521057330.0 and the name of the fabric cutting device. Traditional fabric cutting devices are prone to offset when cutting elastomer fabrics, resulting in an uneven cutting surface, which affects the processing quality of the product.

[0016] The utility model provides a cloth cutting device which is applied in the production process of TPU composite fabrics.

[0017] Please refer to Figure 1 to Figure 2 As shown, a cloth cutting device of the utility model comprises a frame 1, wherein the frame 1 is provided with a workbench 2 and a feed roller 3 and a discharge roller 4 respectively located on both sides of the workbench 2;

[0018] The frame 1 is provided with a lifting block 5 above the workbench 2, and a shearing cutter 51 is provided at the bottom of the lifting block 5. The side walls of the lifting block 5 facing the feed roller 3 and the discharge roller 4 are both inclined downward pressing surfaces 52, and the inclined downward pressing surfaces 52 are provided with strip grooves 521. The strip grooves 521 are slidably matched with the pressing block 53, and the pressing block 53 is provided with an inclined supporting surface 531 abutting against the inclined downward pressing surface 52.

[0019] From the above description, it can be seen that the beneficial effects of the utility model are: a cloth cutting device, a lifting block 5 is designed to be liftable, and a guillotine 51 is provided at the bottom of the lifting block 5. When the lifting block 5 descends, two pressing blocks 53 slidingly arranged on both sides first press the cloth on both sides of the position to be cut. As the lifting block 5 continues to descend, under the abutment and cooperation between the inclined lower pressing surface 52 and the inclined supporting surface 531, the two pressing blocks 53 apply a thrust to both sides to the cloth on both sides of the position to be cut, ensuring that the cloth is flattened. After the lifting block 5 descends to a certain height, the guillotine 51 cuts it from the middle of the cloth. The cloth cutting device provided by the utility model can reduce the probability of deviation when cutting the elastomer cloth, ensure the flatness of the cutting surface, and improve the processing quality of the product.
