Detailed Implementation
[0016] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.
[0017] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.
[0018] like Figure 1 - Figure 4 As shown, this application provides an automatic metal sheet coating device, including: a support frame 1, a transmission roller group 2 fixedly installed in the middle of the inner side of the support frame 1, a film output roller 3 rotatably connected to one side of the top of the support frame 1, the film output roller 3 being used for the transmission of film raw materials, and an isolation collection roller 4 rotatably connected to the top of the support frame 1 away from the film output roller 3, the isolation collection roller 4 being used for the collection of the remaining film isolation paper tape after coating; Specifically, such as Figure 1 As shown, a laminating roller 5 is connected to the inner top of the support frame 1. The position of the laminating roller 5 is used for peeling the film from the release paper. A bonding roller 6 is connected to the inner top of the support frame 1 near the laminating roller 5. The bonding roller 6 is used to press the film attached to the metal plate to improve the tightness of the adhesion.
[0019] Specifically, such as Figure 2As shown, the top of the conveyor roller group 2 is provided with a plate partition 7, which is used to separate the metal plates. The plate partition 7 has a partition groove on its inner side, which is adapted to the movable cutting knife 24. The top inner side of the support frame 1 is slidably connected with a bonding pressure rod 23. The bonding pressure rod 23 is connected to the top of the support frame 1 by a spring, which facilitates adding an elastic pressure to the film on the metal plate. The middle of the top of the support frame 1 is slidably connected with a movable cutting knife 24. After the film is applied, the movable cutting knife 24, which has the same transverse adjustment structure as the sliding frame 8, slides over the inner side of the plate partition 7 to cut the metal plate after film application.
[0020] The synchronous cleaning assembly includes a sliding frame 8, which is slidably connected to one end of the inner side of the support frame 1. A dust suction hood 9 is fixedly connected to the bottom end of the sliding frame 8. The dust suction hood 9 is used to adsorb dust generated during the cleaning of the inner side of the cleaning roller of the cleaning frame 13. A rotating connector 11 is provided on one side of the dust suction hood 9. The bottom end of the rotating connector 11 is connected to the cleaning frame 13. The synchronous cleaning assembly is used for synchronous cleaning during the metal plate coating and transmission. Specifically, such as Figure 3 As shown, a fixed plate 10 is fixedly connected to one side of the dust hood 9. A rotating connector 11 is rotatably connected to the bottom end of the fixed plate 10. A slider 12 is rotatably connected to the bottom end of the rotating connector 11. A cleaning frame 13 is slidably connected to the bottom end of the slider 12. An elastic guide rod 14 that is slidably connected to the slider 12 is fixedly connected to the inner side of the cleaning frame 13. The fixed plate 10 and the cleaning frame 13 are supported by the rotatably adjustable rotating connector 11. The slider 12 slides and adjusts inside the top wall of the cleaning frame 13. Springs on the outer side of the elastic guide rod 14 are also fixedly connected to the inner side of the two sliders 12. Through the elastic force of the springs, the cleaning roller at the bottom end of the cleaning frame 13 can improve the tightness when it contacts the metal plate, which facilitates improved cleaning efficiency.
[0021] The side pressure limiting assembly includes a mounting plate 15, which is fixedly connected to the front and rear ends of the support frame 1. A sliding frame 18 is provided on one side of the mounting plate 15, and a roller 20 with a shaft is connected to the inner side of the sliding frame 18. The side pressure limiting assembly is used for side limiting protection when the metal plate is transported.
[0022] Specifically, such as Figure 4 As shown, a sliding support frame 16 is fixedly connected to the top of the mounting plate 15. An elastic connecting rod 17 is slidably connected to the inner side of the outer wall of the sliding support frame 16. A sliding frame 18 is slidably connected to the inner side of the sliding support frame 16 and fixedly connected to the elastic connecting rod 17. The sliding frame 18 is slidably connected to the sliding support frame 16 through the elastic connecting rod 17, and is fixedly connected to the inner wall of the sliding support frame 16 through the spring on the outer side of the elastic connecting rod 17, so that the position of the sliding frame 18 can be adjusted adaptively within a certain range.
[0023] Specifically, such as Figure 4As shown, the top wall of the sliding frame 18 has a gourd hole 19 that is adapted to the rod of the roller 20 with shaft. The roller 20 passes upward through the larger diameter of the gourd hole 19. After the roller 20 moves, the rod is locked in the smaller diameter of the gourd hole 19, which is convenient for subsequent positioning.
[0024] Specifically, such as Figure 4 As shown, an elastic connector 21 is slidably connected to one side of the top of the sliding frame 18, and a positioning plate 22 is fixedly connected to one side of the elastic connector 21. The edge of the positioning plate 22 is provided with a U-shaped groove that matches the rod of the roller 20 with shaft. The positioning plate 22 is fixed to the top of the sliding frame 18 by screws. The movement of the positioning plate 22 can synchronously replace multiple rollers 20 with shaft, thereby improving maintenance efficiency.
[0025] In this embodiment: During the metal plate transport process, the feed end of the transport roller group 2 is equipped with a sliding frame 8 that can move left and right, which drives the cleaning roller on the inner side of the cleaning frame 13 to wipe the metal plate. The connection of the auxiliary rotating connector 11 is used for height adaptation adjustment. After cleaning, the dust suction hood 9 is used for adsorption treatment to ensure the cleanliness. During the transport of the plate, in order to ensure the accuracy of the coating position, an adjustable mounting plate 15 is set for positioning. The inner side is provided with an elastically connected sliding frame 18 for bonding and pressing. The rubber rollers 20 with shafts that are easy to remove and replace at the same time are used to bond and limit the side of the metal plate to ensure the stability of the plate during transport and further ensure the coating quality of the metal plate.
[0026] Specifically, during the metal plate transfer process, a sliding frame 8 capable of left and right lateral movement is installed at the feed end of the transfer roller group 2. During the movement of the sliding frame 8, the fixed plate 10 on one side of the dust hood 9 and the cleaning frame 13 are supported by a rotatable adjustable rotating connector 11. The slider 12 slides within the top wall of the cleaning frame 13. Springs on the outer side of elastic guide rods 14 are fixedly connected to the inner sides of the two sliders 12. The spring force increases the tightness of the cleaning roller at the bottom of the cleaning frame 13 when it contacts the metal plate, causing the cleaning roller on the inner side of the cleaning frame 13 to adhere to the metal plate for wiping. After cleaning, the metal plate is adsorbed by the dust hood 9. Then, during transfer, the sliding frame 18 is slidably connected to the sliding receiving frame 16 via an elastic connecting rod 17, and the springs on the outer side of the elastic connecting rod 17 connect to the inner wall of the sliding receiving frame 16. The fixed connection allows for adaptive adjustment of the position of the sliding frame 18 within a certain range, ensuring that the rollers 20 on the inner side of the sliding frame 18 are tightly attached to the metal plate. While the metal plate is being transported, the film output roller 3 is used to transport the film raw material. Then, the film is peeled off from the release paper by the coating roller 5. Subsequently, the bonding pressure roller 6 presses the film attached to the metal plate, improving the tightness of the film-metal plate adhesion. Finally, the isolation collection roller 4 is used to collect the remaining film release paper strip after coating. After the metal plate is coated, the moving cutter 24, which has the same transverse adjustment structure as the sliding frame 8, slashes across the inner side of the plate spacer 7 to cut the film. The positioning plate 22 on the outer side of the rollers 20 is fixed to the top of the sliding frame 18 by screws. The movement of the positioning plate 22 can synchronously change multiple rollers 20, improving the maintenance efficiency of the equipment.
