The rotation of the rotating shaft will drive the grinding roller to rotate, and the grinding roller will grind the leather. At the same time, the vacuum cleaner is started, and the rotation of the rotating shaft will also drive the reciprocating screw to rotate. The rotation of the reciprocating screw will cause the moving block to move back and forth in the horizontal direction through the action of the thread.

The rotation of the vacuum cleaner will drive the suction head to rotate, increasing the contact area of the suction head and improving the range of dust collection.

[0013] Optionally, the cleaning assembly includes a cylinder fixedly mounted on one end of the suction head, wherein the piston end of the cylinder penetrates the side wall of the suction head and extends inwardly and is connected to a cleaning block, and the cleaning block matches the suction head.

[0014] By adopting the above technical solution, the cylinder is started, and the cylinder drives the cleaning block to move to clean the dust on the inner wall of the suction head.

[0015] Optionally, a slide groove is provided at the top end of the U-shaped frame, a slider is slidably connected in the slide groove, and the lower end of the slider is connected to the moving block.

[0017] Optionally, a sliding rod is fixedly connected to the inner groove wall of the sliding groove, the sliding rod passes through the slider, and the slider is slidably connected to the sliding rod.

[0018] By adopting the above technical solution, the slider is prevented from falling out of the slide groove.

The rotation of the gear will be rotated by the force of the rack. The rotation of the rotating rod will drive the vacuum cleaner to rotate. The rotation of the vacuum cleaner will drive the suction head to rotate, thereby increasing the contact area of the suction head and improving the range of dust collection.
