Description

Technical Field

[0002] In the textile processing and footwear and hat processing industries, it is usually necessary to perform various processing on the produced fabrics, and cutting equipment is required to cut the fabrics into pieces of fabrics of required specifications.

[0003] Traditional cutting equipment (publication number: CN116926940A) uses an external drive device to make the cutting head perform high-frequency puncturing, and the puncturing is connected into lines for cutting. This is very easy to produce burrs during cutting, and edge sealing cannot be performed, so further processing is required after cutting, which increases production costs.

[0004] Or use improved cutting equipment (publication number: CN205075121 U) for cutting, which can reduce and avoid material breakage and burrs at the incision, but the blade of the tool is a protruding bevel blade. When the fabric thickness is large, it needs to move downward excessively to complete the fabric cutting, and it is still impossible to achieve efficient cutting. In addition, only the blade edge is set for cutting. When the resistance is large, the blade is easy to break, affecting production efficiency.
