Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of grey cloth processing, especially to a trimming device for polyester grey cloth processing. BACKGROUND

[0002] In the production process of polyester grey cloth, the trimming process is a key link to ensure the flatness of the cloth edge and eliminate the burr. Because of the characteristics of high strength, corrosion resistance and easy electrostatic adsorption, the grey cloth is prone to have uneven edges and accumulated burrs during weaving. If not handled in time, it will not only affect the quality of subsequent dyeing and printing processes, but also easily lead to appearance defects of finished cloth.

[0003] According to the search, the China patent with the publication number CN216585876U provides a precise trimming device for polyester grey cloth processing. The device places the cloth on the trimming table and uses the air cylinders on both sides to lower the trimming blades to trim the two sides of the cloth. For different widths of cloth and burrs, the motor drives the bidirectional threaded rod to rotate, causing the relative movement of the sliders on both sides and changing the distance between them, thereby adapting to different widths of cloth and burrs.

[0004] However, during use, it was found that the device only transports the cloth through the fixed roller shaft, without considering the thickness difference and tension fluctuation of the cloth, which easily leads to the deviation or wrinkles of the grey cloth, affecting the trimming accuracy. The burrs and dust generated during the trimming process are easily scattered on the workbench and the surface of the grey cloth. If not cleaned in time, the debris can easily embed into the cloth fibers, causing defects during subsequent winding and affecting the trimming effect of polyester grey cloth processing.
