[0015] The following is combined with Figure 1-3 The specific implementation methods of the utility model are further described.

[0016] The conveyor belt cleaning device of a CNC leather automatic cutting machine comprises a fixed bracket 13, which is installed on the bottom of a CNC equipment side bracket 4 through an M14 nut 8 and an M14 screw 9. A lead screw nut 11 is fixed on the fixed bracket 13 through an M6 screw 12. A lead screw 10 passes through the fixed bracket 13 and the lead screw nut 11 and is threadedly connected with the lead screw nut 11. A rotating handle 14 is fixedly connected to the bottom end of the lead screw 10, and a top end of the lead screw 10 is threadedly connected to a bearing seat 7. A Vientiane bearing 5 is installed in the bearing seat 7. A spiral brush roller 6 is installed in the Vientiane bearing 5. The spiral brush roller 6 is connected to an air motor 19 through a locking sleeve 20. The air motor 19 is respectively connected to an air pipe quick plug-in 17 and a muffler 18. The air pipe quick plug-in 17 is connected to a flow regulating valve 15 through an air pipe 16, and the flow regulating valve 15 is connected to an air source.

[0017] The CNC equipment roller bracket 1 fixes the CNC equipment conveyor belt roller 2 by screws and fixing blocks, the CNC equipment conveyor belt 3 is sleeved on the CNC equipment conveyor belt roller 2, and the CNC equipment side bracket 4 is connected to the CNC equipment roller bracket 1 by screws.
