A dust collection box is installed on the top of the trapezoidal hood, and a filter plate is provided in the inner cavity of the dust collection box. A box cover is installed on the top of the dust collection box, and a negative pressure pump is installed on the box cover. Dust collection pipes are connected to both sides of the dust collection box, and the other ends of the two dust collection pipes are connected to the hollow structure of the trapezoidal hood.

[0007] Preferably, a slide groove is provided on the support plate, a slider is slidably connected in the slide groove, a second drive motor is installed at the front end of the slider, and a pressure roller is fixedly connected to the driving end of the second drive motor.

[0008] Preferably, a spring is fixedly connected to the top of the inner cavity of the slide groove, and the other end of the spring is fixedly connected to the slider.

[0009] Preferably, bolts are passed through the four corners of the top of the box cover, and the four bolts are threadedly connected to the top surface of the dust collection box.

[0010] Preferably, an anti-slip pad is fixedly connected to the outer side of the pressure roller, and the anti-slip pad is elastic.

[0011] Preferably, a servo motor is installed on the top of the support plate, and the driving end of the servo motor is fixedly connected to the lead screw.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The utility model combines structures such as a polishing roller, a trapezoidal cover, a dust collection box, a negative pressure pump, a filter plate, an air suction port, a screw rod, an adjusting slot, an adjusting block and a servo motor. The polishing roller contacts and rotates with the leather on the conveying platform, and then the second drive motor is started to drive the pressure roller to rotate, so that the pressure roller drives the leather on the conveying platform to move. At the same time, the negative pressure pump is started to cooperate with the air suction holes on both sides of the trapezoidal cover to vacuum the leather before polishing, and at the same time, the debris generated after the leather is polished is sucked and stored in the dust collection box, thereby preventing the debris remaining before the leather is polished from affecting the quality of the leather polishing, and preventing the debris after polishing from remaining on the leather surface, without the need for manual cleaning by personnel, which is more convenient.

[0014] 2. The utility model combines a spring and a rubber pad. The spring is always in a compressed state, so that the elastic force of the spring pushes the slider to move downward, thereby ensuring stable contact between the pressure roller and the leather. At the same time, the anti-slip pad is used to increase the friction between the pressure roller and the leather, further ensuring that the rotation of the pressure roller can pull the leather to move, so that the leather can be polished continuously, thereby improving the efficiency of leather polishing.
