[0026] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0027] This invention aims to provide a film coating device, which includes a base assembly 1 on which a first wall plate 14 and a second wall plate 15 are symmetrically arranged. A coating roller assembly 2, a guide roller assembly 3, a traction roller assembly 4, a glue roller assembly 5, and a coating assembly 6 are arranged between the wall plates. The wall plates are fixedly connected by connecting square tubes 16 and screwed to the base assembly 1. During installation, the wall plates are mounted against milled grooves on a positioning plate 13 to ensure high parallelism between the two wall plates. The coating roller assembly 2 is installed in the upper middle part of the wall plate. The film 10 is located between the coating head 17 and the coating roller 21, and is tangential to the coating roller 21. The main function of the coating roller is to rotate evenly and have good contact with the substrate, ensuring that the glue forms a uniform coating on the substrate surface, and guiding and supporting the film 10. The coating assembly 6 and the coating head 17 are horizontally positioned to the left of the coating roller 21. The coating head 17 is connected to the coating head fixing plate 18 by screws. The coating head fixing plate 18 is then connected to the moving block 609 on the glue coating assembly 6 by screws and slides synchronously with the moving block 609. The glue coating assembly 6 can control the horizontal extension and retraction of the coating head 17. During operation, the coating head 17 is pushed out and close to the film material so that it can spray glue onto the film material. There are two guide roller assemblies 3, which are respectively set on the lower right side of the glue coating roller 21 and the outer side of the wall panel. The function of the guide roller assembly 3 is to guide and support the film material 10 used in the coating process, ensuring that the film material 10 passes through each process step smoothly and stably in the coating equipment. The traction roller assembly 4 is installed on the lower right side of the wall panel. The traction roller 41 on it is tangent to the glue roller 57. When the equipment is working, the film material 10 is clamped between the traction roller 41 and the glue roller 57. The rotation of the traction roller 41 provides power to the film material 10 and conveys it backward.

[0028] In this embodiment, the base assembly 1 consists of a support foot 11, a base square tube 12, and a positioning plate 13. The support foot 11 is welded to the lower side of the base square tube 12, and the positioning plate 13 is welded to the upper side of the base square tube 12. The support foot 11 has a screw hole and a through hole. The screw hole is used to fix the equipment, and the through hole can be used to adjust the parallelism of the overall equipment with the horizontal line to ensure that the equipment is in a horizontal position after it is fixed. The positioning plate 13 has a milled groove on its surface. The milled groove on the positioning plate 13 is machined in one piece. There is a positioning boss next to the milled groove. The wall panel is installed on the milled groove to ensure that the two wall panels have a high degree of parallelism. The wall panel is fixedly connected to the positioning plate 13 by screws.

[0029] In this embodiment, the glue-applying roller assembly 2 includes a glue-applying roller 21, a first bearing support 22, a first motor mounting base 23, a first reducer 24, a first servo motor 25, and a first spring coupling 26. The glue-applying roller 21 is installed between two wall panels, with its two ends supported by the first bearing support 22. The first motor mounting base 23 is installed on the outside of the wall panel and is fixedly connected to the wall panel by screws. The first reducer 24 and the first servo motor 25 are fixed to the first motor mounting base 23 by screws. The first motor mounting base 23 has a round hole. The output shaft of the first reducer 24 is connected to the glue-applying roller 21 through the first spring coupling 26. After the first servo motor 25 rotates, it is reduced by the first reducer 24 and then driven by the first spring coupling 26 to work, thereby realizing the rotation function of the glue-applying roller 21. The first spring coupling 26 can absorb and buffer the impact and vibration in the transmission system, reduce the axial, radial, or angular displacement errors during operation, and improve the reliability and stability of the system.

[0030] In this embodiment, the guide roller assembly 3 includes a guide roller 31, a guide roller support 32, a pressure sensor 33, and a guide roller assembly fixing plate 34. The guide roller assembly 3 is installed on the right side of the wall panel and fixed to the wall panel with screws. The guide roller support 32 is installed at both ends of the guide roller 31. The guide roller support 32 is fixed to the pressure sensor 33 with screws. The pressure sensor 33 is then fixed to the guide roller assembly fixing plate 34 with screws. The guide roller 31 can guide the film material 10 in the equipment, so that the film material 10 runs along the correct path and avoids problems such as wrinkles and breakage of the film material 10 due to uneven tension or path deviation. At the same time, the pressure sensor 33 set at both ends of the guide roller 31 can monitor the tension of the film material in real time and feed it back to the control system to control the running status of the traction roller 41.

[0031] In this embodiment, the traction roller assembly 4 includes a traction roller 41, a second bearing support 42, a second servo motor 43, a second reducer 44, a second motor mounting base 45, and a second spring coupling 46. In the working state, the traction roller 41 is tightly tangential to the rubber roller 57. The traction roller 41 rotates and drives the rubber roller 57 to rotate in the opposite direction, so that the film material 10 clamped therein can be transported back and forth. The second servo motor 43, the second reducer 44, the second motor mounting base 45, and the second spring coupling 46 are all installed on the outside of the wall panel. The second reducer 44 is connected to the traction roller 41 through the second spring coupling 46 and is driven by the second servo motor 43, thereby realizing the rotation of the traction roller 41.

[0032] In this embodiment, the rubber roller assembly 5 includes a rocker arm 51, a rocker arm support 52, a threaded rod support plate 53, a first threaded rod 54, a first knob 55, a threaded rod fixing plate 56, a rubber roller 57, a first cylinder 58, and a cylinder lug 59. The rocker arm support 52 is fixed to the inner side of the wall panel by screws. The rocker arm 51 is rotatably connected to the rocker arm support 52, enabling a swinging function. The rubber roller 57 is mounted on the upper part of the rocker arm 51, and its left side is rotatably connected to the first cylinder 58. The fixed end of the first cylinder 58 is provided with a cylinder lug 59, which is rotatably connected to the rocker arm support 52. 58 can control the rocker arm 51 to swing, and the swing of the rocker arm 51 further drives the rubber roller 57 to swing; the right side of the rocker arm 51 is provided with a first threaded rod 54, which is installed in the screw hole of the threaded rod support plate 53 and supported and fixed by the threaded rod fixing plate 56. By rotating the first knob 55, the first threaded rod 54 can move left and right within the threaded rod support plate 53. During the process of the rubber roller 57 and the traction roller 41 clamping the film material 10, the rocker arm 51 is limited and adjusted by the first threaded rod 54, which can ensure that the pressure pressed on the film material 10 is controllable and evenly distributed.

[0033] In this embodiment, the adhesive application assembly 6 consists of a first slider 601, a first guide rail 602, a second knob 603, a threaded rod fixing seat 604, a second threaded rod 605, a limit adjustment block 606, a first mounting block 607, a second cylinder 608, a moving block 609, a second mounting block 610, a second slider 611, a second guide rail 612, a fixing seat 613, and a bearing 614. The limit adjustment block 606 is mounted on the first slider 601, with the second threaded rod 605 disposed in the middle. The two ends of the second threaded rod 605 are fixed by the threaded rod fixing seat 604. By rotating the second knob 603, the limit adjustment block 606 can move up and down. The limit adjustment block 606 is provided with a slanted boss, which can be used to make fine adjustments to the left and right positions of the coating head 17 to ensure that both ends of the coating head 17 have the same position. The telescopic displacement; the second mounting block 610 is fixedly connected to the moving block 609, the moving block 609 is fixedly connected to the second guide rail 612, the second guide rail 612 is slidably connected to the second slider 611, the second slider 611 is installed on the upper side of the fixed seat 613, and the telescopic action of the second cylinder 608 can drive the moving block 609 fixed to the second mounting block 610 to move, thereby controlling the movement of the coating head 17; two mounting blocks 607 are symmetrically installed on the second mounting block 610, and a bearing 614 is provided in the middle of the mounting blocks 607. When working, the bearing 614 is tangent to the limit adjustment block 606. By rotating the second knob 603 to adjust the position of the limit adjustment block 606, the distance and parallelism between the coating head 17 and the coating roller 21 can be controlled, thereby controlling the thickness and uniformity of the glue sprayed on the film material 10.

[0034] The specific usage and function of this embodiment are as follows:

[0035] See appendix Figure 1-5 In this embodiment, the coating device is located in the front-end process of the coating machine before the film material enters the oven. When the coating machine produces film material, two films of different materials need to be pressed together by a laminating machine to form a new roll film. In order to achieve the lamination of film materials, adhesive must be applied between the two films. After the adhesive is applied, the film material 10 enters the heating oven to complete the drying and curing of the adhesive. Then, it is pressed together with another film material in the laminating machine to form a new roll film. The equipment for applying adhesive is the coating device. When the coating device is used for the first time, the film material 10 needs to be manually passed through the inside of the device along a predetermined route. The specific route is as follows: from the upper part of the guide roller assembly 3 with pressure sensor 33 to the lower part of the traction roller 41, then pulled from the other end of the traction roller 41 to the guide roller assembly 3 inside the coating device, then through the adhesive coating roller 21, and finally pulled to the heating oven for baking.

[0036] See appendix Figure 1-5The adhesive coating process in this embodiment is as follows: First, the first servo motor 25 and the second servo motor 43 are started to drive the coating roller 21 and the traction roller 41 to start rotating. Then, the rocker arm 51 is controlled by the first cylinder 58 to make the coating roller 57 close to the traction roller 41. Subsequently, the film material 10 begins to be conveyed in the coating device. The switch of the second cylinder 608 is turned on, so that its piston rod extends and pushes the mounting block 610 and the moving block 609 forward. The coating head fixing plate 18 is then pushed towards the coating roller 21 and close to it. At this time, the coating head 17 fixed on the coating head fixing plate 18 moves and closes to the film material 10. The adhesive supply system is started, and the adhesive is evenly applied to the surface of the film material 10 through the nozzle of the coating head 17. The film material 10 after being coated with adhesive is transported upward. The coating thickness is detected in real time by a thickness gauge and the data is fed back to the control system. Based on the measurement data, it can be determined whether the relative distance between the nozzle of the coating head 17 and the film material 10 is consistent, thereby ensuring the coating quality.

[0037] When the adhesive coating thickness on the film material 10 is uneven, the movement of the limit adjustment block 606 can be controlled by rotating the second knob 603. The limit adjustment block 606 is in tangential contact with the bearing 614. Its up-and-down movement will drive the bearing 614 to move back and forth. Since the bearing 614 is fixed on the mounting block 610, its back-and-forth movement will further drive the moving block 609 to move. By adjusting the displacement of the moving block 609, the position of the coating head 17 can be adjusted, thereby adjusting the distance between the two ends of the coating head 17 and the film material 10, ensuring the uniformity of the coating thickness. This process can effectively improve the uniformity and quality of the product.

[0038] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
