DETAILED DESCRIPTION

[0016] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0017] like Figure 1-3The coating device shown in the figure is for carton production, comprising a coating machine body 1 and a laminating roller 11, the surfaces of the two brackets of the coating machine body 1 are both installed with support blocks 3, the tops of the two support blocks 3 are both movably installed with circular plates 5, the circular plates 5 are connected to a driving motor 2, a second connecting rod 6 is installed between the two circular plates 5, the side of the second connecting rod 6 is arranged along the side of the circular plate 5, the laminating roller 11 is located below the second connecting rod 6, the surface of the second connecting rod 6 is movably sleeved with a plurality of movable tubes 15, the surfaces of the plurality of movable tubes 15 are all installed with first connecting rods 4, groove plates 12 are movably installed between the bottom ends of the plurality of first connecting rods 4, the groove plates 12 and the two support blocks 3 are elastically connected, both ends of the laminating roller 11 are installed on the two ends of the groove plate 12 through bearings, the top of the groove plate 12 is installed There are multiple fixed blocks 13, and fixed shafts 14 are installed on the sides of multiple fixed blocks 13. The multiple fixed shafts 14 are respectively installed on the sides of multiple first connecting rods 4. The driving motor 2 controls the circular motion of the circular plate 5, and the circular plate 5 drives another circular plate 5 to move synchronously in an arc through the second connecting rod 6. During the circular motion of the second connecting rod 6, the second connecting rod 6 drives the first connecting rod 4 to move in an arc through the movable tube 15. At the same time, the other end of the first connecting rod 4 moves in an arc on the surface of the fixed shaft 14, so that the second connecting rod 6 can drive the groove plate 12 to move in the vertical direction during the circular motion, so as to drive the film pressing roller 11 to press on the top of the carton board, and as the carton board moves, the carton board drives the film pressing roller 11 to move in an arc while moving, which facilitates the movement of the carton board.

[0018] The top ends of the two support blocks 3 are both equipped with rotating shafts through bearings. The two circular plates 5 are respectively installed at one end of the two rotating shafts. The other end of one of the rotating shafts is connected to the driving motor 2. When the rotating shaft is subjected to force, it drives the circular plate 5 to move in an arc, making it convenient for the driving motor 2 to control the circular motion of the circular plate 5.

[0019] The sides of the two support blocks 3 are provided with long holes 7, and the inside of the long holes 7 are installed with fixed rods 8. The surface movable sleeve of the fixed rod 8 is provided with a slider 9, and the surface movable sleeve of the fixed rod 8 is provided with a compression spring 10.

During the downward movement of the groove plate 12, the groove plate 12 drives the two sliders 9 to slide on the surfaces of the two fixed rods 8, so that the groove plate 12 can move stably in the vertical direction. At the same time, the two sliders 9 apply external force to the two compression springs 10. The length of the compression spring 10 shrinks after being subjected to force. At this time, the compression spring 10 is in a contracted state. During the upward movement of the groove plate 12, the compression spring 10 pushes the slider 9 in the opposite direction. After being subjected to force, the slider 9 drives the groove plate 12 upward to move, thereby improving the stability of the groove plate 12 in the vertical direction.

[0020] A support plate 16 is installed between the two brackets of the coating machine body 1. The support plate 16 is located in the conveyor belt of the coating machine body 1. The positions of the support plate 16 and the film pressing roller 11 correspond to each other. The support plate 16 is used to support the conveyor belt after being subjected to force, reducing the downward movement of the carton board under force and improving the stability of the carton board under force.
