The outer wall of the block 86 is in contact with the inner wall of the slot. The contact between the two can fix the multiple positions of the rotating roller 84 driven by the slider 83.

[0035] Working principle: After the polyester-viscose fabric is twisted into yarn by two sets of twisting rollers 5, the yarn is passed through the inner wall of the cleaning cylinder 92 to be wound on the surface of the winding roller 3. At this time, the motor 7 is started to let its output shaft drive the reciprocating screw rod 6 to rotate. At the same time, the reciprocating screw rod 6 will drive the pulley A10 to rotate when it rotates, and the pulley A10 will let the pulley B11 rotate synchronously with it through the conveyor belt. When the pulley B11 rotates, it will drive the winding roller 3 to rotate, so as to wind the yarn, and when the yarn passes through the cleaning cylinder 92, it will be cleaned by the soft brush on its inner wall to remove dust on the surface of the yarn. At the same time, the reciprocating screw rod 6 will drive the sliding seat 91 to move back and forth when it rotates, so that the yarn can be evenly wound on the surface of the winding roller 3 to avoid accumulation on one side of its surface.

[0036] At the same time, when it is necessary to adjust the tension when winding the yarn, the block 86 can be pulled by grasping the frame of the outer wall of the block 86 to drive the insertion rod 87 to move. At this time, the bottom end of the insertion rod 87 will be separated from the through hole of the current position of the fixed column B82, and the block 86 will be separated from the slot hole of the current position of the fixed column A81, and the limit spring 85 will be elastically compressed during the pulling process. At this time, the block 86 can be directly moved to drive the two sets of sliders 83 and the rotating roller 84 to descend, thereby squeezing and applying pressure to the upper end of the yarn. When it is adjusted to a suitable position, the block 86 is released and it will be elastically acted upon by the limit spring 85 to restore it to its initial position to contact the inner wall of the slot hole of the current position of the fixed column A81, thereby fixing the position of the block 86, and the insertion rod 87 will also be plugged into the through hole of the current position of the fixed column B82, thereby fixing the positions of the two sets of sliders 83, and also fixing the position of the rotating roller 84.

[0037] At the same time, when it is necessary to replace and clean the cleaning cylinder 92, the two sets of wedge blocks 95 can be pulled to make their bottom ends disengage from the slots of the two sets of guide blocks 93 on the outer wall of the cleaning cylinder 92, thereby disassembling the cleaning cylinder 92. When the cleaning is completed and the installation is completed, the guide block 93 is directly inserted into the inner wall of the sliding seat 91. At this time, the outer wall of the guide block 93 will squeeze the inclined surface of the wedge block 95, pushing it outward on the inner wall of the sliding seat 91 until the guide block 93 is fully inserted into the inner wall of the sliding seat 91. The two sets of wedge blocks 95 will be restored to their initial positions by the elastic action of the return spring 94, thereby engaging with the slots of the guide block 93, thereby quickly installing the cleaning cylinder 92.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
