[0024] The outer circumference of the telescopic rod of cylinder 8 is engraved with scale 9 along its length. The operator can judge the synchronization of telescopic movement by observing the scale 9 values ​​on the output arms of the two cylinders 8, so as to ensure that the needle roller 4 always remains horizontal.

[0025] The dust collection unit includes a dust collection hood 10, which has an arc-shaped structure. The dust collection hood 10 is detachably installed between two fixed frames 3 and located on the side of the needle roller 4. The opening end of the dust collection hood 10 faces the surface of the fabric 17. The dust collection hood 10 is connected to an air extraction pipe 12. The end of the air extraction pipe 12 away from the dust collection hood 10 extends to the outside of the frame 1. The air extraction pipe 12 can be connected to a vacuum cleaner via a quick connector. A notch 13 is provided on the edge of the dust collection hood 10 near the needle roller 4. Dust particles enter the interior of the dust collection hood 10 through the notch 13. The curvature of the notch 13 matches the outer circumferential curvature of the needle roller 4.

[0027] The notch 13 of the dust collection hood 10 located below is set inside the collection tank 14 to avoid the collection tank 14, so that the dust collection hood 10 and the collection tank 14 do not affect each other.

[0028] Working principle: In operation, the fabric 17 to be processed is first passed through the guide rollers 2 inside the frame 1. The distance between the needle roller 4 and the fabric 17 is adjusted using a cylinder according to the thickness of the fabric 17 and processing requirements. An air pump, controlled by a solenoid valve, supplies air to the cylinder 8, pushing the slider 7 down along the auxiliary rod 6 and sliding groove 5, bringing the needle roller 4 closer to the fabric 17. The scale 9 on the output arm of the cylinder 8 is observed to ensure that the two cylinders 8 extend and retract synchronously, keeping the needle roller 4 horizontal (a lead screw can also be used to drive the slider; if a lead screw is used, rotating the lead screw drives the slider 7 to raise and lower the needle roller 4, and the precise adjustment of the distance between the needle roller 4 and the fabric 17 is achieved by controlling the number of rotations of the lead screw). After the distance adjustment is complete, the cleaning motor 18 is started. The cleaning motor 18 drives the needle roller 4 to rotate around its own axis via a drive pulley, transmission belt, and driven pulley. The needle-like bristles on the surface of the needle roller 4 are guided by the guide rollers below. 2. The surface of the conveyed fabric 17 is brushed and combed. At the same time, the external vacuum cleaner is started. The dust collection hood 10 forms a negative pressure area through the notch 13 and the open end, sucking in the lint generated by the needle roller 4 and conveying it into the vacuum cleaner through the suction pipe 12. During the rotation of the needle roller 4, the needle-like bristles on its surface pass through the serrated structure at the top of the collection tank 14. The tips of the serrated structure scrape off the debris adhering to the bristles. The scraped debris falls into the collection tank 14. The drive motor corresponding to the collection tank 14 is started. The drive motor drives the rotating shaft 15 and the spiral blade 16 to rotate. The spiral blade 16 conveys the debris in the collection tank 14 along the length of the collection tank 14 to one end and discharges it, realizing the centralized collection and processing of debris. During the whole process, all components work together to complete the brushing and combing of the fabric 17 and the collection of impurities, ensuring the processing effect and the cleanliness of the production environment.
