Description

TECHNICAL FIELD

[0001] The utility model belongs to carbon equipment technical field, concretely relates to a kind of deviation rectification grooving roller and aluminium foil carbon coating system. BACKGROUND

[0002] Currently in the field of aluminium foil carbon coating, deviation rectification operation is needed before carbon coating after aluminium foil unwinding, before entering oven and before winding to prevent aluminium foil deviation. The existing deviation rectification roller is rubber smooth roller, and aluminium foil needs to run from above or below the deviation rectification roller. Due to oil stains, oil spots and aluminium powder on the surface of aluminium foil, aluminium powder and oil stains will accumulate on the surface of deviation rectification roller after long-time equipment operation, which will cause the following problems: 1. deformation of deviation rectification roller, leading to deviation rectification failure; 2. aluminium foil edge will scratch the deviation rectification roller, and the scratched deviation rectification roller will scratch the surface of aluminium foil; 3. surface concave-convex points will be generated on the surface of deviation rectification roller and aluminium foil, affecting the use of deviation rectification roller and leading to unqualified aluminium foil products.

[0003] When the deviation rectification roller is dirty with aluminium powder, it needs to be cleaned every day, for example, it needs to be cleaned at least when each shift is replaced. The aluminium foil needs to be removed for cleaning, and the aluminium foil needs to be rethreaded after cleaning. It takes 1-2 hours each time, which seriously affects production efficiency. When the deviation rectification roller is deformed and scratched, it needs to be replaced, which is time-consuming and laborious and increases production cost.

[0004] To solve the above problems, the utility model is proposed. UTILITY MODEL CONTENTS

[0005] The first aspect of the present application provides a kind of deviation rectification grooving roller, the deviation rectification grooving roller includes: aluminium roller main body;

[0006] The aluminium roller main body is a cylinder, and the aluminium roller main body is configured to be rotatable along the central axis of the cylinder under driving;

[0007] The surface of the aluminium roller main body has a plurality of grooves spaced along the direction of the central axis.

[0008] Preferably, the grooves extend along the rotation direction of the aluminium roller main body.

[0009] Preferably, the cross section of the groove is concentric with the cross section of the cylinder, so that the groove extends along the rotation direction of the aluminium roller main body.

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

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

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

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

[0014] Among them, at least one of the first deviation rectifying roller, the third deviation rectifying roller and the fourth deviation rectifying roller is the deviation rectifying grooved roller of the first aspect.

[0015] Preferably, a second deviation rectifying roller is further arranged between the first deviation rectifying roller and the positive coating A roller.

[0016] A fifth deviation rectifying roller and a sixth deviation rectifying roller are further arranged between the fourth deviation rectifying roller and the winding roller.

[0017] At least one of the second deviation rectifying roller, the fifth deviation rectifying roller and the sixth deviation rectifying roller is the deviation rectifying grooved roller of any one of the first aspect.

[0018] Preferably, the positive coating A roller is configured to coat the front surface of the aluminum foil, and the reverse coating B roller is configured to coat the back surface of the aluminum foil.

[0019] The third aspect of the present application provides a method for reducing the concave-convex points on the surface of the aluminum foil in the aluminum foil carbon coating process, the method comprising: using the deviation rectifying grooved roller of the first aspect or the aluminum foil carbon coating system of the second aspect.

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

[0021] 1. In the present application, the surface of the deviation rectifying roller is grooved, and the material of the roller is replaced by aluminum, which avoids the problems of aluminum powder, oil stains and deviation of the aluminum strip on the surface of the deviation rectifying roller. The principle may be that the grooves increase the friction force so that the aluminum strip on them will not deviate, and the aluminum roller will not accumulate aluminum powder and oil stains due to the material.

[0022] 2. In the preferred scheme, the cross section of the groove 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, not other directions, for example, at a certain angle with the side length of the roller or perpendicular to the side length of the roller), so that the groove can provide the maximum friction force in the running direction of the aluminum foil, avoiding the deviation of the aluminum foil.

[0023] 3、The material of the deviation rectifying roller is changed from rubber to aluminum, which has two advantages: first, compared with the rubber roller, the hardness of the deviation rectifying aluminum roller is improved, avoiding the deformation of the aluminum foil strip and the accumulation of oil stains, oil spots and aluminum powder due to the softness of the rubber roller; second, the material of the deviation rectifying aluminum roller is the same as that of the aluminum foil strip, avoiding scratching the aluminum foil when the hardness of the roller is higher than that of the aluminum foil.
