Description

Technical Field

[0001] This utility model relates to the field of pre-coated film manufacturing technology, and in particular to a pre-coated film coating device. Background Technology

[0002] Lamination is a processing technology that involves coating a plastic film with an adhesive and bonding it to printed paper through heating and pressure to form a paper-plastic composite product. This process can improve the performance of the bonded printed materials. Lamination equipment is required during the lamination process of printing paper.

[0003] For example, the pre-coated film coating device disclosed in Chinese Patent No. CN208376190U works as follows: "A worktable is provided at the middle position of the surface of the main body, and the worktable is fixedly connected to the main body. An installation groove is provided on the lower right side of the surface of the worktable, and the installation groove is fixedly connected to the worktable. This pre-coated film coating device has a relatively low manufacturing cost, which greatly reduces the structural complexity of the pre-coated film coating device, thereby reducing the difficulty of production technology, simplifying after-sales maintenance, and reducing maintenance costs. This pre-coated film coating device has the advantages of simplified process, convenient operation, high production flexibility, no environmental pollution, and high production efficiency. The rubber pad can reduce the friction between the support foot and the ground, and play a good protective role for the ground around the device. The anti-wear ring can reduce the friction of the guide plate on the pre-coated film, reduce the wear of the pre-coated film, and facilitate the circulation of this pre-coated film coating device in the market."

[0004] It uses guide plates to guide the pre-coated film and prevent it from shifting during transport. However, the guide plates alone cannot effectively correct the pre-coated film after it has shifted, thus failing to ensure the effect of subsequent lamination. Utility Model Content

[0005] This utility model addresses the shortcomings of existing technologies by providing the following technical solution:

[0006] A pre-coated film coating device includes a housing, a guide component for correcting the orientation of the pre-coated film is provided at one end of the inner side of the housing, an adjustment component for adjusting the surface tension of the pre-coated film is provided on one side of the guide component, a coating component for coating the pre-coated film is provided on one side of the adjustment component, and a traction component for conveying the pre-coated film is provided on one side of the coating component.

[0007] As an improvement to the above technical solution, the guiding assembly includes a first motor, a threaded rod fixedly connected to the output end of the first motor, threaded blocks symmetrically threaded to the outer side of the threaded rod, a second connecting plate fixedly connected to one side of the threaded block, a first connecting plate fixedly connected between the second connecting plates, a third motor fixedly connected to the top of the first connecting plate, a second connecting rod fixedly connected to the top of the third motor, a first connecting rod fixedly connected to one side of both ends of the second connecting rod, a connecting block fixedly connected to the other side of both ends of the first connecting rod, and a correction roller rotatably connected between the connecting blocks.

[0008] As an improvement to the above technical solution, a sliding rod is fixedly connected to the bottom of the first connecting rod, and a sliding groove adapted to the sliding rod is opened on the top of the second connecting plate.

[0009] As an improvement to the above technical solution, a fixing frame is provided on one side of the guide assembly, and ultrasonic edge sensors are symmetrically arranged at the bottom of the fixing frame.

[0010] As an improvement to the above technical solution, the adjustment component includes a horizontal plate fixedly connected to the inner side of the housing. A pressure sensor is fixedly connected to the top of the horizontal plate. A squeezing plate is arranged below the pressure sensor. A plurality of spring dampers are evenly fixedly connected to the bottom of the squeezing plate. A lifting frame is fixedly connected to the bottom of the spring dampers. Guide rods are fixedly connected to both ends of the lifting frame. An upper floating roller is rotatably connected inside the guide rod. A lower floating roller is arranged below the upper floating roller.

[0011] As an improvement to the above technical solution, the coating assembly includes a heating box fixedly connected to the inside of the housing, a brush roller is provided below the heating box, an auxiliary roller is provided on one side of the brush roller, and both the auxiliary roller and the brush roller are rotatably connected to the inside of the housing.

[0012] As an improvement to the above technical solution, the traction assembly includes a second motor, the output end of the second motor is fixedly connected to a lower traction roller, the other end of the lower traction roller is fixedly connected to a lower gear, the outer side of the lower gear is meshed with an upper gear, one side of the upper gear is fixedly connected to an upper traction roller, and the other end of the upper traction roller is rotatably connected to the inside of the housing.

[0013] The beneficial effects of this utility model are:

[0014] When the pre-coated film passes the ultrasonic edge sensor at the bottom of the fixing frame, if the pre-coated film deviates, it will send a signal to the back-end system. The back-end system will then send a command to the guiding component. At this time, as needed, the first motor can be started to drive the threaded rod at its output end to rotate, and through the threaded connection, it will drive the threaded block on the outside of the threaded rod to move. This will drive the second connecting plate connected to the threaded block to move together, and drive the third motor, the second connecting rod, the first connecting rod, the connecting block, and the correction roller to move together. If it is necessary to rotate the correction roller, simply start the third motor to drive the second connecting rod, the first connecting rod, the connecting block, and the correction roller between the connecting blocks to rotate together. When the first connecting rod rotates, it will drive the slide bar at its bottom to rotate together in the slide groove at the top of the second connecting plate, which plays an auxiliary guiding role. This structure can automatically correct deviations in real time, ensuring the straightness of the pre-coated film conveying, improving the coating accuracy, and reducing manual intervention and material waste.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the following provides a more detailed description of the utility model. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the utility model.

[0021] Please refer to Figures 1-4A pre-coated film coating device includes a housing 1. A guide component for correcting the direction of the pre-coated film is provided at one end of the inner side of the housing 1. An adjustment component for adjusting the surface tension of the pre-coated film is provided on one side of the guide component. A coating component for coating the pre-coated film is provided on one side of the adjustment component. A traction component for conveying the pre-coated film is provided on one side of the coating component.

[0022] Specifically, the pre-coated film is pulled and conveyed by the traction component. During the conveying process, the guide component will detect the movement of the pre-coated film in real time and correct it when the pre-coated film deviates. The adjustment component will detect the tension of the pre-coated film surface and adjust it to reduce the wrinkle rate. It can also adapt to pre-coated films of different specifications.

[0023] Please refer to Figures 1-4 The guiding assembly includes a first motor 7, with a threaded rod 16 fixedly connected to the output end of the first motor 7. Threaded blocks 17 are symmetrically threaded to the outer side of the threaded rod 16. A second connecting plate 20 is fixedly connected to one side of the threaded block 17. A first connecting plate 19 is fixedly connected between the second connecting plates 20. A third motor 23 is fixedly connected to the top of the first connecting plate 19. A second connecting rod 24 is fixedly connected to the top of the third motor 23. A first connecting rod 22 is fixedly connected to one side of both ends of the second connecting rod 24. Connecting blocks 25 are fixedly connected to the other side of both ends of the first connecting rod 22. A correction roller 26 is rotatably connected between the connecting blocks 25. A sliding rod 18 is fixedly connected to the bottom of the first connecting rod 22. A sliding groove 21 adapted to the sliding rod 18 is opened on the top of the second connecting plate 20. A fixing frame 2 is provided on one side of the guiding assembly. Ultrasonic edge sensors 15 are symmetrically arranged at the bottom of the fixing frame 2.

[0024] Specifically, when the pre-coated film passes the ultrasonic edge sensor 15 at the bottom of the fixing frame 2, if the pre-coated film deviates, it will send a signal to the background system. The background system will then send a command to the guiding component. At this time, the first motor 7 can be started to drive the threaded rod 16 at its output end to rotate, and through the threaded connection, drive the threaded block 17 on the outside of the threaded rod 16 to move, thereby driving the second connecting plate 20 connected to the threaded block 17 to move together, and driving the third motor 23, the second connecting rod 24, the first connecting rod 22, the connecting block 25, and the correction roller 26 to move together. To rotate the alignment roller 26, simply start the third motor 23 to drive the second connecting rod 24, the first connecting rod 22, the connecting block 25, and the alignment roller 26 between the connecting blocks 25 to rotate together. When the first connecting rod 22 rotates, it will drive the slide bar 18 at its bottom to rotate together in the slide groove 21 at the top of the second connecting plate 20, which plays an auxiliary guiding role. By adjusting the position and angle of the alignment roller 26, the orientation of the pre-coated film can be corrected. This structure can automatically perform alignment correction in real time, ensuring the straightness of the pre-coated film conveying, improving the coating accuracy, and reducing manual intervention and material waste.

[0025] Please refer to Figures 1-4 The adjustment assembly includes a horizontal plate 3 fixedly connected to the inside of the housing 1. A pressure sensor 28 is fixedly connected to the top of the horizontal plate 3. A squeezing plate 29 is provided below the pressure sensor 28. Several spring dampers 13 are evenly fixedly connected to the bottom of the squeezing plate 29. A lifting frame 14 is fixedly connected to the bottom of the spring dampers 13. Guide rods 27 are fixedly connected to both ends of the lifting frame 14. An upper floating roller 30 is rotatably connected inside the guide rod 27. A lower floating roller 31 is provided below the upper floating roller 30.

[0026] Specifically, the lower floating roller 31 is a fixed component and works with the upper floating roller 30 for conveying. When the upper floating roller 30 comes into contact with the pre-coated film, it will move and drive the lifting frame 14 to move together. At this time, the guide rod 27 on the outside of the lifting frame 14 will move in the groove on the inside of the housing 1 to ensure that the movement direction of the lifting frame 14 is vertical. The movement of the lifting frame 14 will drive the spring damper 13 on its top to move and squeeze the extrusion plate 29. The extrusion plate 29 moves under force and squeezes the pressure sensor 28. After being squeezed, the pressure sensor 28 sends a signal to the backend according to the magnitude of the force. The backend system adjusts the spring damper 13 to adapt to the tension of the current pre-coated film. This is existing technology and will not be described in detail. By adjusting the tension, the wrinkle rate of the pre-coated film can be effectively reduced and the coating quality can be improved.

[0027] Please refer to Figures 1-4 The coating assembly includes a heating box 4 fixedly connected to the inside of the housing 1. A brush roller 12 is provided below the heating box 4. An auxiliary roller 11 is provided on one side of the brush roller 12. Both the auxiliary roller 11 and the brush roller 12 are rotatably connected to the inside of the housing 1.

[0028] Specifically, the film material is heated by the heating box 4 and flows downwards, and the pre-coated film surface is coated by the cooperation of the brush roller 12 and the auxiliary roller 11.

[0029] Please refer to Figures 1-4 The traction assembly includes a second motor 8, the output end of the second motor 8 is fixedly connected to a lower traction roller 10, the other end of the lower traction roller 10 is fixedly connected to a lower gear 5, the outer side of the lower gear 5 is meshed with an upper gear 6, one side of the upper gear 6 is fixedly connected to an upper traction roller 9, and the other end of the upper traction roller 9 is rotatably connected to the inside of the housing 1.

[0030] Specifically, by starting the second motor 8, the lower traction roller 10 at its output end is driven to rotate, which in turn drives the lower gear 5 at its other end to rotate together. When the lower gear 5 rotates, it drives the upper gear 6 to rotate together through meshing connection. When the upper gear 6 rotates, it drives the upper traction roller 9 on its other side to rotate together. The movement of the pre-coated film is driven by the cooperation of the upper and lower traction rollers.

[0031] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
