DETAILED DESCRIPTION

[0022] Clearly, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments.

[0024] Fixed plates 16 are installed at one edge of each end of the workbench 1. An unwinding shaft 17 and a winding shaft 18 are rotatably mounted inside the fixed plates 16. A drive wheel 19 and a driven wheel 20 are respectively installed on the outer sides of the unwinding shaft 17 and the winding shaft 18, and the drive wheel 19 and the driven wheel 20 are connected by a belt 21. A support base 22 is installed on one side of one of the fixed plates 16, and a conveyor motor 23 is installed inside the support base 22. One end of the unwinding shaft 17 is connected to the output end of the conveyor motor 23. A control panel 41 is installed on one side of the workbench 1. During operation, in practical applications, when collecting impurities generated during the trimming process, large pieces of fabric impurities can be recycled. Without proper classification of impurities, large pieces of fabric impurities are mixed with fine fiber impurities, increasing the difficulty of recycling the large pieces of fabric impurities later. The unwinding drum is installed outside the unwinding shaft 17, and the winding drum is installed outside the winding shaft 18. The polyester fabric is output from the bottom side of the unwinding drum, passes through the guide roller 25, the support plate 27, and then another guide roller 25, and finally enters the winding drum from the bottom side of the winding drum for winding. The conveyor motor 23 is started, and its output end drives the unwinding shaft 17 to rotate. The drive wheel 19 rotates accordingly, and drives the driven wheel 20 through the belt 21, thereby making the winding shaft 18 rotate synchronously. This ensures that the unwinding and winding of the fabric are carried out simultaneously, continuously providing fabric for the trimming operation and ensuring the continuity of processing.

[0025] During trimming, the negative pressure motor 3 is started, and the three fan blades 4 at the output end of the negative pressure motor 3 rotate at high speed, creating a negative pressure in the dust collection box 2. Under the action of negative pressure, impurities generated during the trimming operation are sucked into the dust collection box 2 through the dust suction hood 9 and the dust suction pipe 8 via the conveying pipe 7. The impurities first pass through the coarse filter 6, where larger pieces of fabric impurities are intercepted, while fine fiber impurities pass through the coarse filter 6. They then continue downwards through the fine filter 5, where even finer fiber impurities are intercepted. This achieves graded processing of impurities, with larger pieces of fabric impurities remaining. The coarse filter screen 6 can be recycled. Meanwhile, the telescopic rod 10 reciprocates under the control of the control panel 41. The telescopic rod 10 drives the mounting plate 11 to reciprocate within the dust collection box 2. The compression spring 13 keeps the claw 14 in contact with the top side of the coarse filter screen 6. When the telescopic rod 10 drives the mounting plate 11 to reciprocate, the claw 14 continuously pushes the large pieces of cloth impurities on the coarse filter screen 6, moving them to prevent accumulation and further promoting the grading effect.
