[0002] Self-adhesive paper is a self-adhesive composite paper product that is widely used in industry and daily life due to its ease of use. Self-adhesive paper is mainly composed of a paper layer and a film layer. The adhesive coating process is a crucial step in the production of self-adhesive paper. The purpose of adhesive coating is to evenly coat the film layer with adhesive on one side. Automating and facilitating the adhesive coating process is a pressing need for enterprises and a key focus of their technological upgrading research; this case study arose from this need. Utility Model Content
[0003] The purpose of this invention is to address the needs of the prior art and provide a film coating device for self-adhesive composite paper. This device is designed with a glue tank that can rotate. After the glue tank rotates downward, the glue liquid can move towards the film guide roller to complete the continuous coating operation on the flowing film layer.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A film coating device for self-adhesive composite paper includes a base, a film-drawing roller, and a glue tank. The film-drawing roller is rotatably mounted on the base surface, and the glue tank is mounted on the side of the film-drawing roller. The glue tank is installed by a flipping motion and contains adhesive liquid. One end of the glue tank is provided with a coating port. When the glue tank flips down, the coating port moves towards the roller surface of the film-drawing roller. The film-drawing roller continuously guides the film layer of the self-adhesive composite paper through, and the adhesive liquid in the glue tank flows out from the coating port and coats the film layer that has flowed through.
[0006] Furthermore, a roller support is fixedly installed on the base, the film-drawing roller is rotatably installed on the roller support, a glue-applying platform is fixedly installed on the base, a trough support is fixedly installed on the glue-applying platform, the non-glue-applying side of the glue trough is rotatably connected to the trough support, and the glue-applying side of the glue trough is free.
[0007] Furthermore, a flipping mechanism is installed below the glue tank. The flipping mechanism includes a flipping drive cylinder and a downward limiting component. One end of the flipping drive cylinder is hinged to the table surface of the glue application platform, and the other end is hinged to the bottom surface of the glue tank. The downward limiting component blocks the downward movement path of the glue tank.
[0008] Furthermore, the downward limiting component includes a rod seat and a limiting screw. The rod seat is fixedly installed on the surface of the glue application platform, and the limiting screw is threadedly connected to the rod seat. The limiting screw is installed vertically, with its top blocking the downward movement path of the glue groove, and a handle connected to its bottom.
[0009] Furthermore, a glue tank is installed inside the glue tank, and a glue inlet is provided at the top of the glue tank. A glue outlet filter is bolted to one side wall of the glue tank, which allows the glue tank and the glue tank to communicate with each other.
[0010] Furthermore, the glue dispensing filter is installed on the side wall of the glue tank facing the glue application port.
[0011] Furthermore, a glue dispensing auxiliary mechanism is installed inside the glue tank. The glue dispensing auxiliary mechanism includes a glue dispensing push cylinder and a glue pushing plate. The glue dispensing push cylinder is fixedly installed on the outside of the glue tank, and the glue pushing plate is disposed inside the glue tank. The glue pushing plate is connected to the piston rod end of the glue dispensing push cylinder, and the glue pushing plate is installed towards the glue dispensing filter screen.
[0012] Furthermore, the glue tank is equipped with a glue application adapter mechanism, which includes two adjustable baffles. Each adjustable baffle is equipped with an adjusting bolt. The adjusting bolt is threaded to the side wall of the glue tank. One end of the adjusting bolt is rotatably connected to the adjusting baffle, and the other end is fixedly connected to a screw head.
[0013] Furthermore, the bottom of the adjusting baffle is covered with a sealing strip made of rubber material, and the sealing strip is in contact with the bottom surface of the inner side of the rubber groove.
[0014] The beneficial effects of this utility model are:
[0015] This invention features a tumbler-shaped glue tank that flips over. After the tumbler flips over, the glue liquid naturally moves towards the film guide roller to complete the continuous glue application on the flowing film layer.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] like Figures 1-5 As shown, a film coating device for self-adhesive composite paper includes a base 1, a film-guiding roller 2, and a glue tank 3. The film-guiding roller 2 is rotatably mounted on the platform of the base 1. A roller support 11 is fixedly mounted on the base 1. The film-guiding roller 2 is rotatably mounted on the roller support 11. The film-guiding roller 2 is used to continuously guide the film layer of the self-adhesive composite paper through the roller. The film-guiding roller 2 can be powered by its own motor or used as a passive roller. This device is generally connected to a self-adhesive paper composite system. The film layer itself has… The power of the flow transmission means that the film-drawing roller 2 can be used as a passive roller, only serving to guide the film layer. The glue tank 3 is installed on the side of the film-drawing roller 2. A glue-applying platform 12 is fixedly installed on the base 1, and a tank support 13 is fixedly installed on the glue-applying platform 12. The glue tank 3 is installed using a flipping motion. The glue tank 3 contains glue liquid, and one end of the glue tank 3 has a glue-applying port 31. The non-glue-applying port 31 side of the glue tank 3 is rotatably connected to the tank support 13, while the glue-applying port 31 side of the glue tank 3 is free. Figure 1 As shown, when the glue tank 3 tilts downwards, the glue application nozzle 31 moves towards the roller surface of the film guide roller 2. The glue from the glue tank 3 flows out from the glue application nozzle 31 and coats the film layer it passes through. As the film layer flows through, glue is continuously applied to it to meet production needs. This invention's glue application operation has the advantages of high efficiency and automation. After the glue application operation is completed, to prevent further outflow of glue, such as... Figure 2As shown, the glue tank 3 of this utility model can be flipped upwards. At this time, the glue application port 31 is tilted upwards, which can effectively prevent the glue from flowing out and keep the remaining glue in the glue tank 3.
[0024] In order to control the flipping motion of the glue tank 3, such as Figure 1 and Figure 2 As shown, the present invention has a flipping mechanism 4 installed below the glue tank 3. The flipping mechanism 4 includes a flipping drive cylinder 41 and a downward flipping limit component 42. One end (bottom end) of the flipping drive cylinder 41 is hinged to the table surface of the glue application platform 12, and the other end (piston rod end) is hinged to the bottom surface of the glue tank 3. When the piston rod of the flipping drive cylinder 41 extends outward, it can form an upward flipping effect of the glue tank 3. When the piston rod of the flipping drive cylinder 41 retracts inward, it can form a downward flipping effect of the glue tank 3. The downward flipping limit component 42 blocks the downward flipping movement path of the glue tank 3 and can control the downward flipping amplitude of the glue tank 3.
[0025] During the adhesive application process, a gap should be maintained between the adhesive application nozzle 31 and the roller surface of the film-drawing roller 2 to prevent the nozzle 31 from scratching the film surface. This gap should be small so that when the adhesive overflows from the nozzle 31, it is directly applied to the film layer by tension, rather than flowing downwards. The gap between the adhesive application nozzle 31 and the film-drawing roller 2 is achieved by limiting the downward tilting range of the adhesive trough 3. The downward tilting range of the adhesive trough 3 is achieved by the downward tilting limiting component 42. Figure 5 As shown, the downward limiting assembly 42 includes a rod base 421 and a limiting screw 422. The rod base 421 is fixedly installed on the table surface of the glue application platform 12. The limiting screw 422 is threadedly connected to the rod base 421. The limiting screw 422 is installed vertically. The top of the limiting screw 422 blocks the downward movement path of the glue tank 3. The bottom of the limiting screw 422 is connected to a handle 423. The handle 423 can help to turn the limiting screw 422. The limiting screw 422 can move vertically up and down. The gap between the glue application port 31 and the film guide roller 2 is controlled by the contact effect between the bottom surface of the glue tank 3 and the limiting screw 422.
[0026] like Figures 1-3 As shown, a glue tank 5 is installed inside the glue tank 3. The glue tank 5 is used for glue feeding. The top of the glue tank 5 is equipped with a glue inlet 51, through which the glue is pumped in. A glue outlet filter 52 is bolted to one side wall of the glue tank 5, allowing the glue tank 3 and glue tank 5 to communicate. The input glue may have agglomerates, which will affect the coating quality of the membrane layer. The glue in the glue tank 5 is output from the glue outlet filter 52 to the glue tank 3. During the process of passing through the glue outlet filter 52, the glue is screened to form a uniform glue output, ensuring coating quality. Figure 3 As shown, the glue dispensing filter 52 is installed on the side wall of the glue tank 5 facing the glue application port 31. The output glue flows directly to the glue application port 31. The glue dispensing filter 52 adopts a detachable bolt fixing structure to facilitate disassembly and cleaning operations.
[0027] Given the viscous consistency and low fluidity of the adhesive, it is difficult to discharge it through the dispensing filter 52. Therefore, if... Figure 1 As shown, a dispensing auxiliary mechanism 53 is installed inside the glue tank 5. The dispensing auxiliary mechanism 53 includes a dispensing push cylinder 531 and a push plate 532. The dispensing push cylinder 531 is fixedly installed on the outside of the glue tank 3. The push plate 532 is set inside the glue tank 5. The push plate 532 is connected to the piston rod end of the dispensing push cylinder 531. The push plate 532 is installed towards the dispensing filter screen 52. When the piston rod end of the dispensing push cylinder 531 extends outward, the push plate 532 pushes the glue liquid in the glue tank 5 towards the dispensing filter screen 52, so that it can be smoothly and quickly discharged into the glue tank 3.
[0028] Different types of self-adhesive paper come in different widths, therefore the adhesive film layer that needs to be applied also has different widths. In view of the above, if... Figure 3 As shown, the glue tank 3 is equipped with a glue application adapter mechanism 6. The glue application adapter mechanism 6 includes two adjustable baffles 61. Each adjustable baffle 61 is equipped with an adjusting bolt 62. The adjusting bolt 62 is threaded to the side wall of the glue tank 3. One end of the adjusting bolt 62 is rotatably connected to the adjusting baffle 61, and the other end is fixedly connected to a screw head 63. The screw head 63 can help to turn the adjusting bolt 62. When the adjusting bolt 62 is turned, it can push the adjusting baffle 61 to move. When the two adjusting baffles 61 move relative to each other, the glue outlet width of the glue application port 31 becomes smaller, which can adapt to small-width film layers. When the two adjusting baffles 61 move in opposite directions, the glue outlet width of the glue application port 31 becomes larger, which can adapt to large-width film layers. This utility model has good product production adaptability.
[0029] like Figure 4 As shown, the bottom of the adjusting baffle 61 is covered with a sealing strip 611. The sealing strip 611 is made of rubber material and contacts the inner bottom surface of the glue tank 3. The sealing strip 611 has a sealing effect on the inner bottom surface of the glue tank 3, preventing leakage at the bottom of the adjusting baffle 61.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
