[0031] refer to Figure 1 and Figure 2 , according to the thin film switching device of the embodiment of the utility model,

[0032] Bracket 100;

[0033] A first traction roller 110, both left and right ends of the first traction roller 110 are rotatably connected to the bracket 100, and the first traction roller 110 is used for winding the film;

[0034] A second traction roller 120, both left and right ends of the second traction roller 120 are rotatably connected to the bracket 100, the second traction roller 120 is arranged above the first traction roller 110, and the second traction roller 120 is used for winding the film;

[0035] The reversing roller 130, the first adapter 140 and the second adapter 150, the reversing roller 130 is perpendicular to the up and down direction, the angle between the reversing roller 130 and the second traction roller 120 is to the left, the reversing roller 130 is used for winding the film, the first adapter 140 is rotatably connected to the bracket 100, the second adapter 150 is slidably connected to the bracket 100, the end of the reversing roller 130 close to the second traction roller 120 is rotatably connected to the first adapter 140, and the end of the reversing roller 130 away from the second traction roller 120 is rotatably connected to the second adapter 150, so that the end of the reversing roller 130 away from the second traction roller 120 can swing in a circle around the end of the reversing roller 130 close to the second traction roller 120, and change the angle between the reversing roller 130 and the second traction roller 120 and the movement direction of the film.

The film wound around the first traction roller 110 and the second traction roller 120 moves from back to front. Since there is an angle between the reversing roller 130 and the second traction roller 120, the film wound around the reversing roller 130 will turn, thereby changing the moving direction of the film. The first adapter 140 is rotatably connected to the bracket 100, and the second adapter 150 is slidably connected to the bracket 100. The end of the reversing roller 130 close to the second traction roller 120 is rotatably connected to the first adapter 140, and the end of the reversing roller 130 away from the second traction roller 120 is rotatably connected to the second adapter 150.

[0037] On the other hand, the angle-adjustable reversing roller 130 can adapt to different film materials and optimize the steering effect by adjusting the angle, ensuring that the film is not affected by stretching deformation, wrinkles and other problems during the steering process.

An arc guide groove 161 is formed on the arc plate 160, and the second adapter 150 is slidably connected to the inner wall of the arc guide groove 161. It can be understood that the arc side wall of the arc guide groove 161 guides the movement of the second adapter 150, so that the second adapter 150 can make a circular motion around the rotation center of the first adapter 140, and further, the end of the reversing roller 130 away from the second traction roller 120 can make a circular swing around the end of the reversing roller 130 close to the second traction roller 120. The arc side wall of the arc guide groove 161 uses the rotation axis of the first adapter 140 as the rotation axis.

[0042] refer to Figure 3 As an embodiment of the present invention, a roller is rotatably connected to the second adapter 150, and the roller is disposed in the arc-shaped guide groove 161 and abuts against the arc-shaped side wall of the arc-shaped guide groove 161. It can be understood that the rotation axis of the roller is parallel to the up-down direction, the roller is disposed in the arc-shaped guide groove 161 and abuts against the arc-shaped side wall of the arc-shaped guide groove 161, and the roller can roll on the arc-shaped side wall of the arc-shaped guide groove 161. Under the interaction between the roller and the arc-shaped guide groove 161, the roller can guide the movement of the second adapter 150, so that the second adapter 150 can make a circular motion around the rotation axis of the first adapter 140.

The offset detection component is used to detect the offset of the film. When the offset detection component 200 detects that the offset of the film exceeds the qualified offset range, the offset detection component 200 will transmit a signal to the traction mechanism in the coating production line, and the traction mechanism will drive the film to move so that the film can fall into the qualified offset range, which is conducive to ensuring the coating quality of the coating production line.
