Specific embodiments

[0021] 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.

[0022] Please refer to Figures 1-5 , an embodiment provided by the present utility model:

[0023] A coating device for epoxy-coated aluminum foil coating: It includes a paint tank 1. The interior of the paint tank 1 stores the paint for epoxy coating or aluminum foil coating. A motor 11 is fixedly connected to the surface of the paint tank 1. A coating roller 12 is fixedly connected to the output shaft of the motor 11. The sheet material will be conveyed above the coating roller 12. The motor 11 drives the coating roller 12 to rotate through the output shaft. During the rotation of the coating roller 12, the paint inside the paint tank 1 will be attached to the sheet material to complete the coating work of the coating layer. A feed pipe 13 is provided on the surface of the paint tank 1. A cleaning mechanism is provided on the surface of the paint tank 1. The cleaning mechanism includes a support frame 2. The support frame 2 is fixedly connected to the surface of the paint tank 1. A fixed cleaning roller 21 is rotatably connected to the surface of the support frame 2. A movable rod 22 is slidably connected to the surface of the support frame 2. A connecting frame 23 is fixedly connected to the surface of the movable rod 22. A movable cleaning roller 24 is rotatably connected to the surface of the connecting frame 23. A spring 25 is fixedly connected to the surface of the support frame 2. One end of the spring 25 away from the support frame 2 is fixedly connected to the surface of the connecting frame 23. Cleaning cloths are provided on the surfaces of the fixed cleaning roller 21 and the movable cleaning roller 24. This cleaning mechanism can clean the sheet material to be processed through the cleaning cloths on the connecting frame 23 and the movable cleaning roller 24, avoid the existence of dust on the sheet material, improve the quality of the coating layer on the sheet material, and avoid the appearance defects of the coating layer on the sheet material.

[0024] Further, a limiting mechanism is provided on the surface of the paint box 1. The limiting mechanism includes a fixing frame 3 which is fixedly connected to the surface of the paint box 1. A cross bar 31 is fixedly connected to the surface of the fixing frame 3. A lifting cylinder 32 is fixedly connected to the surface of the fixed cleaning roller 21. A support block 33 is fixedly connected to the piston rod of the lifting cylinder 32. A limiting roller 34 is rotatably connected to the surface of the connecting frame 23. When some relatively thin plates are coated on the coating roller 12, due to the bulging phenomenon of the plates, the coating effect of the coating layer on the plates is poor. This limiting mechanism can make the plates flat when the coating roller 12 is coating, so as to ensure the uniformity of the coating of the plates on the coating roller 12.

[0025] Further, the connecting frame 23 and the movable cleaning roller 24 slide up and down on the surface of the support frame 2 through the movable rod 22. The connecting frame 23 is in a "C" shape. The elastic force of the spring 25 acts on the connecting frame 23, so that the connecting frame 23 drives the movable cleaning roller 24 to slide towards the fixed cleaning roller 21. The plate is placed between the fixed cleaning roller 21 and the movable cleaning roller 24. During the rotation of the fixed cleaning roller 21 and the movable cleaning roller 24, the dust on the plate is taken away by the cleaning cloth. The fixed cleaning roller 21 and the movable cleaning roller 24 can be applied to the cleaning of plates with different thicknesses.

[0026] Further, the movable cleaning roller 24 and the fixed cleaning roller 21 are parallel to each other, and the fixed cleaning roller 21 and the movable cleaning roller 24 have the same length, so that the fixed cleaning roller 21 and the movable cleaning roller 24 can cover plates with different widths.

[0027] Further, the cleaning cloths of the fixed cleaning roller 21 and the movable cleaning roller 24 are installed by using Velcro. The hook surfaces of the Velcro are provided on the fixed cleaning roller 21 and the movable cleaning roller 24, and the loop surfaces of the Velcro are provided on the cleaning cloth. The loop surfaces of the Velcro are provided on both sides of the cleaning cloth. The cleaning cloth can be rolled into a cylindrical shape and installed on the fixed cleaning roller 21 and the movable cleaning roller 24. At the same time, it is also convenient to remove and clean the cleaning cloths on the cross bar 31 and the movable cleaning roller 24.

[0028] Further, there are two groups of fixing frames 3. The paint box 1 supports the cross bar 31 through the fixing frames 3. There are also two groups of cross bars 31, and the cross bars 31 are arranged at both ends of the top of the coating roller 12.

[0029] Further, the lifting cylinder 32 drives the support block 33 to lift on the cross bar 31 through the piston rod. The support block 33 drives the limiting roller 34 to lift synchronously. The limiting roller 34 is located directly above the coating roller 12, and the length of the limiting roller 34 is the same as that of the coating roller 12. The limiting roller 34 rotates on the support block 33 to reduce the friction between the plate and the limiting roller 34.

[0030] Working principle: The sheet is passed through between the fixed cleaning roller 21 and the movable cleaning roller 24. The connecting frame 23 slides on the support frame 2 through the movable rod 22. The elastic force of the spring 25 acts on the connecting frame 23, and the connecting frame 23 drives the movable cleaning roller 24 to move towards the sheet, so that the movable cleaning roller 24 presses the sheet against the surface of the fixed cleaning roller 21. During the conveying process of the sheet, the fixed cleaning roller 21 and the movable cleaning roller 24 are driven to rotate at the same time. During the rotation process of the fixed cleaning roller 21 and the movable cleaning roller 24, the dust on the sheet is taken away by the cleaning cloth, improving the quality of the coating on the sheet and avoiding appearance defects of the coating on the sheet.

[0031] The coating tank 1 supports the cross bar 31 through the fixed frame 3. The lifting cylinder 32 drives the support block 33 to descend on the cross bar 31 through the piston rod. The support block 33 drives the limiting roller 34 to descend towards the coating roller 12. The limiting roller 34 limits the sheet for coating on the coating roller 12, avoiding the phenomenon of the sheet bulging, ensuring the flatness of the sheet, and thus ensuring the uniformity of the coating of the sheet on the coating roller 12.

[0032] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present invention. Any reference signs in the claims should not be regarded as limiting the claims involved.
