Technical Field

[0001] The utility model relates to the technical field of release film manufacturing, in particular to a coating structure for manufacturing a PET release film. Background Technique

[0002] A release film is a film used in the production and processing process, usually made of plastics, rubber, adhesives or other materials. Coating is the process of applying a coating on the outer surface of an object. In the manufacturing of release films, coating usually refers to applying a special coating material on the outer surface of the film to increase the surface tension and anti-sticking property of the film. Coating is a relatively key step in the manufacturing of release films. However, when the existing coating machine is coating, the solution in the coating tank will be continuously consumed. Once the staff observes incorrectly and does not replenish the consumed solution, it will cause the film to be uncoated, resulting in a large number of unqualified products. Content of the Utility Model

A valve is arranged on the outer surface of the connecting hose, and the connecting hose is connected to the coating box.

[0006] With the above technical solution, when the paint in the paint box is consumed, due to the connection effect produced by the setting of the connecting hose, the paint in the paint storage tank can automatically flow into the interior of the paint box to fill the paint in the paint box. At the same time, the remaining amount of paint can be clearly observed through the paint storage tank.

[0007] Preferably, a first spring is provided between the sliding block and the frame body, and the height of the paint roller is flush with that of the active guide roller.

[0008] With the above technical solution, the sliding block can be pulled by the first spring to make the paint roller move along with the film fed in and be tensioned, preventing the film from slackening when it moves.

[0009] Preferably, a rotating pressing mechanism is provided between the frame body and the active guide roller, and different thicknesses of films can be adjusted and clamped through the rotating pressing mechanism.

[0010] With the above technical solution, by pressing down the rotating rod, the driven guide roller can be pushed towards the active guide roller to clamp films of different thicknesses, and the clamping force between the active guide roller and the driven guide roller can be adjusted by tightening or loosening the adjusting screw.

[0011] Preferably, the rotating pressing mechanism includes: a pressing slider which is respectively slidably installed at the upper and lower ends of the frame body, and a driven guide roller is rotatably installed inside the pressing slider, and the side surface of the driven guide roller is in contact with the side surface of the active guide roller. A second spring is provided between the pressing slider and the frame body. A rotating positioning slider is slidably installed inside the frame body, and the outer surface of the rotating positioning slider is penetrated by the rotating rod, and the rotating rod is rotatably connected to the rotating positioning slider. The section of the rotating rod inside the rotating positioning slider is eccentrically designed, and a pushing pin is slidably installed on the outer surface of the rotating positioning slider.

[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0029] Please refer to Figures 1-6, the present utility model provides a technical solution: a coating structure for manufacturing PET release films, including a frame body 1. The frame body 1 is designed in a concave shape, and a sliding block 4 is slidably installed on the outer surface of the frame body 1. A coating roller 7 is fixedly installed on the side surface of the sliding block 4. A driving guide roller 8 is rotatably installed on the outer surface of one end of the frame body 1, and the driving guide roller 8 is located on both the upper and lower sides of the frame body 1. A drying box 18 is fixedly installed on the outer surface of the end of the frame body 1 away from the driving guide roller 8, and a through hole is provided on the outer surface of the frame body 1 near the drying box 18. A coating storage box 2 is fixedly installed at the end of the frame body 1 away from the drying box 18, and the coating storage box 2 is made of a transparent material. A filling mechanism is provided between the frame body 1 and the sliding block 4. Through the filling mechanism, the coating is automatically loaded after use to keep the coating full. The filling mechanism includes: a coating box 6. The coating box 6 is fixedly installed on the side surface of the sliding block 4, and the coating box 6 is connected to the shaft of the coating roller 7. The coating storage box 2 is designed to be airtight, and connecting hoses 3 are respectively installed through the side surface of the coating storage box 2. One connecting hose 3 is fixedly installed on the side of the coating storage box 2 close to the frame body 1, and the other connecting hose 3 is connected to the end of the coating storage box 2 away from the frame body 1. A valve is provided on the outer surface of the connecting hose 3, and the connecting hose 3 is connected to the coating box 6.

[0030] After the machine starts, the film will be pushed by the rotation of the driving guide roller 8 and the driven guide roller 9, and the surface of the film will be coated by the coating roller 7. The rotation of the coating roller 7 takes away the coating in the coating box 6. After long-term use, the liquid level of the coating in the coating box 6 decreases. Due to the design of the connecting hose 3, the coating in the coating storage box 2 can flow into the coating box 6 to fill the coating in the coating box 6. It is only necessary to observe the solution in the coating storage box 2.

[0031] A first spring 5 is provided between the sliding block 4 and the frame body 1, and the height of the coating roller 7 is level with that of the driving guide roller 8.

[0032] By pulling the sliding block 4 with the first spring 5, the coating roller 7 can be driven to move upward, tensioning the inserted film, so that the film will not become slack during the movement process, reducing the probability of winding of the driving guide roller 8 and the driven guide roller 9, and at the same time keeping the film straight and flat.

[0033] A rotating pressing mechanism is arranged between the frame body 1 and the active guide roller 8.

Then, press the rotating rod 13 to make the rotating rod 13 rotate to eject the top pin 14, push the rotating positioning slider 12 towards the fixing plate 15, so that the top pin 14 ejects the pressing slider 10, clamping the active guide roller 8 and the driven guide roller 9. At the same time, the clamping force between the active guide roller 8 and the driven guide roller 9 can be conveniently adjusted by adjusting the screw 16, preventing the film from being clamped and broken during movement, facilitating the clamping of different thicknesses of films, and adjusting the clamping force at the same time. And after the active guide roller 8 and the driven guide roller 9 are wound with materials, it is convenient to open the active guide roller 8 and the driven guide roller 9 to take out the wound materials.

[0035] A drying positioning roller 19 is rotatably installed at one end of the frame body 1 close to the drying box 18, and one side of the frame body 1 close to the drying positioning roller 19 is inclined. A rear cover 20 is rotatably installed at one end of the frame body 1 away from the active guide roller 8, and ventilation holes are evenly opened on the outer surface of the rear cover 20.
