Since the driven roller 6 is placed above the coating roller 5 to press the material, the rotation of the coating roller 5 drives the material to be conveyed, and then drives the driven roller 6 to rotate. The paint is coated on the material through the relative movement between the coating roller 5 and the material.

[0020] According to the attached Figure 2 , 3 , as shown in the figure: An anti-paint component 8 is provided on one side of the C-shaped frame one 4.

Then, the motor 12 is started to drive the coating roller 5 to rotate. The coating roller dips the coating material from the coating tank 3, and the rotation of the coating roller 5 drives the material to be conveyed, thereby driving the driven roller 6 to rotate. The coating material is coated on the material through the relative movement between the coating roller 5 and the material.

[0024] Through the coating removal assembly 8, the scraping knives 11 on both sides are driven to move towards and away from each other in the reverse direction, so that the position of the scraping knives 11 can be adjusted to a suitable position according to the width of the two sides of the material. Since the material conveyed to the other side of the coating roller 5 is continuously conveyed, the excessive viscous material attached to both sides of the material can be scraped off by the scraping knives 11, so as to prevent the coating material on the two sides of the material from being uneven, which affects the coating effect.
