A typical coating machine includes a safety system, a tension control system, a tension detection system, a winding and unwinding system, a coating system, a drying system, a corona system, an automatic correction system, a roll diameter detection system, and opposing clamping bushings on both sides. The core in the middle is clamped by the opposing clamping bushings on both sides, and then the roll is unwound in the unwinding direction. It then enters the post-processing stage, where the coating is applied by pressing the coating roller against the surface of the gravure roller.
[0003] However, the inventors discovered that aluminum powder remains on the surface of the aluminum foil after production, which can lead to incomplete coating, star spots, and black spots caused by dirt on the rollers during the production process, affecting the performance of the coated products. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by using wool felt to clean the surface of aluminum foil. The wool felt roller drives the cleaning component to slide on the support plate via a gear and rack mechanism. The cleaning component moves in opposite directions with the wool felt roller to remove impurities, which are then sucked away by a high-frequency suction fan. This solves the problem that some aluminum powder remains on the surface of the aluminum foil after production, which can lead to incomplete coating, star spots, and black spots due to roller contamination during production, thus affecting the performance of the coated product.

The cleaning component is equipped with a high-frequency suction fan. The wool felt roller cleans the surface of the aluminum foil. The wool felt roller drives the cleaning component to slide on the support plate through a gear and rack mechanism. The cleaning component and the wool felt roller move towards each other to remove impurities from the wool felt roller, and the high-frequency suction fan sucks away the impurities.
[0007] As a preferred embodiment, the cleaning assembly includes a brush plate slidably disposed on a support plate and an air suction duct disposed on the brush plate, the air suction duct being made of a stretchable flexible material.
[0008] As a preferred embodiment, the brush plate is provided with a wind shield, the brush plate is provided with toothed racks on both sides, and the brush plate is provided with a plurality of sliding blocks.
[0009] As a preferred embodiment, the transmission assembly includes half gears disposed on both sides of the wool felt roller, and the half gears are provided with a plurality of teeth corresponding to the rack.
[0010] As a preferred embodiment, the wool felt roller is provided with transmission gears on both sides.
[0011] As a preferred embodiment, the support plate is provided with a plurality of slide rails for the sliding block to slide on, and a return spring is provided between the slide rails and the sliding block.
[0012] As another preferred embodiment, the brush plate is arranged in an arc shape.
[0013] The beneficial effects of this utility model are:
[0014] In this invention, the surface of aluminum foil is cleaned using wool felt. The wool felt roller drives the cleaning component to slide on the support plate through a gear and rack mechanism.

[0023] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.
[0024] Example 1
[0025] like Figures 1 to 5 As shown, an apparatus for cleaning foil materials during the coating process in the lithium battery industry includes a support plate 1 and a wool felt roller 2. A transmission component 3 is provided on the wool felt roller 2, and a cleaning component 4 is slidably disposed on the support plate 1. A high-frequency suction fan 5 is provided on the cleaning component 4. The wool felt 2 cleans the surface of the aluminum foil 6. The wool felt roller 2 drives the cleaning component 4 to slide on the support plate 1 through a gear and rack mechanism. The cleaning component 4 and the wool felt roller 2 move towards each other to remove impurities from the wool felt roller 2, and the high-frequency suction fan 5 sucks away the impurities.
[0026] It is worth mentioning that the surface of the aluminum foil 6 is cleaned by the wool felt 2. The wool felt roller 2 drives the cleaning component 4 to slide on the support plate 1 through a gear and rack mechanism. The cleaning component 4 and the wool felt roller 2 move in opposite directions to remove impurities from the wool felt roller 2 and the impurities are sucked away by the high-frequency suction fan 5, realizing automated cleaning and improving production yield. The wool felt roller 2 is made of high-quality soft wool felt and soft, non-deformable brush, which can effectively solve the problem of residual aluminum powder on the surface of aluminum foil.
[0027] like Figure 2 As shown, the cleaning component 4 includes a brush plate 41 slidably disposed on a support plate 1 and a suction duct 42 disposed on the brush plate 41, the suction duct 42 being made of a stretchable flexible material.
[0028] In this example, the impurities on the wool felt 2 are cleaned by sliding the brush plate 41 back and forth, and the impurities are sucked away by the suction pipe 42. The suction pipe 42 is made of a stretchable flexible material, so that the brush plate 41 is not restricted by the suction pipe 42 when sliding back and forth.
[0029] like Figure 2 As shown, a wind shield 43 is provided on the brush plate 41, and toothed racks 44 are provided on both sides of the brush plate 41. Several sliding blocks 45 are provided on the brush plate 41.
[0030] In this example, the impurities cleaned by the brush plate 41 are blocked by the hood 43 so that they can be sucked away by the suction pipe 42 to prevent contamination; the brush plate 41 is fixed to the support plate 1 and slid by the sliding block 45.
[0031] like Figure 2 As shown, the transmission assembly 3 includes half gears 31 disposed on both sides of the wool felt roller 2, and the half gears 31 are provided with a plurality of teeth 32 corresponding to the rack 44.
[0032] In this example, the brush plate 41 is driven to slide by the meshing of the half gear 31 and the rack 44.
[0033] like Figure 2 As shown, both sides of the wool felt roller 2 are equipped with transmission gears 21.
[0034] like Figure 4 As shown, the support plate 1 is provided with a plurality of slide rails 11 for sliding blocks 45 to slide, and a return spring is provided between the slide rails 11 and the sliding blocks 45.
[0035] In this example, the brush plate 41 can be reset after sliding to the other side by the reset spring, so that the brush plate 41 can slide back and forth to clean the wool felt roller 2 over a wide area.
[0036] like Figure 1 As shown, the brush plate 41 is arranged in an arc shape.
[0037] In this example, the arc-shaped design increases the contact area between the brush plate 41 and the wool felt roller 2, which helps to expand the cleaning range and make the cleaning more thorough.
[0038] The above description is merely a preferred embodiment of this utility model, but the scope of protection of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art under the technical guidance of this utility model should be included within the scope of protection of this utility model. Therefore, the scope of protection of this utility model should be determined by the scope of the claims.
