[0022] To realize the cleaning of foreign matter, arc plate 5 is arranged between two load-bearing frames 2, arc plate 5 is set to two, square box 6 is fixedly connected between two arc plates 5, scraping strip 7 is fixedly connected to the top of square box 6, and scraping strip 7 cooperates with first coating roller 3 and second coating roller 4. Figure 3 When square box 6 is close to second coating roller 4, scraping strip 7 will be attached to the outer wall of second coating roller 4, then control second coating roller 4 to rotate clockwise, and scraping strip 7 can push and scrape foreign matter on the outer wall of second coating roller 4, and the falling foreign matter enters the inside of square box 6.

[0023] The bottom of square box 6 is communicated with suction pipe 8, one end of suction pipe 8 away from square box 6 is communicated with the air suction treatment pipeline of factory, and in specific use, foreign matter entering the inside of square box 6 can be quickly sucked away.

[0024] In order to realize the control of the position of the square box 6, a lifting control assembly cooperating with the arc plate 5 is arranged between the two bearing frames 2, and the lifting control assembly comprises a first support 13, an electric push rod 14, a second support 15 and a second rotating shaft 17. The first support 13 and the second support 15 are both in U-shaped structure, and the first support 13 is fixedly connected between the top portions of the two bearing frames 2. The electric push rod 14 is fixedly connected to the upper surface of the top portion of the first support 13, and the top portion of the first support 13 is provided with a circular opening through which the telescopic end of the electric push rod 14 extends, and the second support 15 is fixedly connected to the telescopic end of the electric push rod 14.
