Description

Technical Field

[0001] The invention belongs to the technical field of carbon coating equipment, and in particular relates to a deviation-correcting slotting roller and an aluminum foil carbon coating system. Background Art

[0002] At present, in the field of aluminum foil carbon coating, correction operations are required after the aluminum foil is unrolled and before carbon coating, before entering the oven, and before winding to prevent the aluminum foil from deviating. The existing correction roller is a rubber smooth roller, and the aluminum foil needs to run from above or below the correction roller. Due to the presence of oil stains, oil spots, and aluminum powder on the surface of the aluminum foil, after long-term operation of the equipment, the surface of the correction roller will be enriched with aluminum powder and oil stains, resulting in the following problems: 1. The correction roller is deformed, resulting in correction failure; 2. The edge of the aluminum foil will scratch the correction roller, and the scratched correction roller will tear the surface of the aluminum foil; 3. Surface bumps will appear on the correction roller and the surface of the aluminum foil, affecting the use of the correction roller and causing the aluminum foil product to be unqualified.

[0003] When the deflection correction roller is contaminated by aluminum powder, it needs to be cleaned every day, for example, at least every shift. When cleaning, the aluminum foil on the deflection correction roller needs to be removed, and the aluminum foil needs to be re-threaded after cleaning. Each time takes up to 1-2 hours, which seriously affects production efficiency. When the deflection correction roller is deformed and strained, a new roller needs to be replaced, which is more time-consuming and labor-intensive, and also increases production costs.

[0004] In order to solve the above problems, the present invention is proposed. Summary of the invention

[0005] A first aspect of the present application provides a deviation-correcting and grooving roller, the deviation-correcting and grooving roller comprising: an aluminum roller body;

[0006] The aluminum roller body is a cylinder, and the aluminum roller body is configured to be able to rotate along the central axis of the cylinder under driving;

[0007] The surface of the aluminum roller body is provided with a plurality of grooves spaced apart and distributed along the direction of the central axis.

[0008] Preferably, the groove extends along a rotation direction of the aluminum roller body.

[0009] Preferably, the groove cross section and the cylindrical cross section are in a concentric circle structure, so that the groove extends along the rotation direction of the aluminum roller body.

[0010] Preferably, the roughness of the aluminum roller surface is greater than that of the rubber roller surface.

[0011] Preferably, the width of the groove is 1-2 mm, and the distance between two adjacent grooves is 18-22 mm.

[0012] Preferably, the depth of the groove is 1-2 mm.

[0013] The second aspect of the present application provides an aluminum foil carbon coating system, the aluminum foil carbon coating system comprising: an unwinding roller, a first deviation correction roller, a positive coating roller A, a first drying oven, a third deviation correction roller, a reverse coating roller B, a second drying oven, a fourth deviation correction roller, and a winding roller arranged in sequence from upstream to downstream;

[0014] Among them, at least one of the first deviation-correcting roller, the third deviation-correcting roller, and the fourth deviation-correcting roller is the deviation-correcting and grooving roller described in the first aspect.

[0015] Preferably, a second deviation-correcting roller is further provided between the first deviation-correcting roller and the positive coating A roller;

[0016] A fifth and a sixth deviation-correcting roller are arranged in sequence from upstream to downstream.

[0017] At least one of the second correcting roller, the fifth correcting roller, and the sixth correcting roller is the correcting and grooving roller described in any one of the first aspects.

[0018] Preferably, the positive coating roller A is configured to carbon-coat the front side of the aluminum foil; and the negative coating roller B is configured to carbon-coat the back side of the aluminum foil.

[0019] The third aspect of the present application provides a method for reducing the uneven spots on the surface of aluminum foil during the aluminum foil carbon coating process, the method comprising: using the deviation-correcting grooving roller described in the first aspect or the aluminum foil carbon coating system described in the second aspect.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The present application makes grooves on the surface of the correction roller and replaces the material of the roller with aluminum instead of rubber, thereby avoiding the problem of aluminum powder, oil stains and aluminum strip deviation on the surface of the correction roller. The principle may be that the grooves increase the friction so that the aluminum strip on it will not deviate, and the aluminum roller will not accumulate aluminum powder and oil stains due to its material.

[0022] 2. In a preferred solution, the groove cross section is concentric with the cylindrical cross section, so that the groove extends along the rotation direction of the aluminum roller body. At this time, the side length of the groove is parallel to the side length of the roller (the side length of the groove is not in other directions, such as forming a certain angle with the side length of the roller or being perpendicular to the side length of the roller). In this way, the groove can provide the maximum friction force in the running direction of the aluminum foil to prevent the aluminum foil from running off.

[0023] 3. The material of the correction roller is changed from rubber to aluminum, which has two advantages: first, compared with the rubber roller, the hardness of the correction aluminum roller is improved, which prevents the rubber roller from being soft and easy to deform, thus causing the aluminum foil to deform and accumulate oil stains, oil spots, and aluminum powder; second, the material of the correction aluminum roller is the same as that of the aluminum foil, which prevents the aluminum foil from being scratched when the hardness of the roller is higher than that of the aluminum foil.
