Description

Technical Field

[0001] This utility model relates to the technical field of metal foil cleaning equipment, specifically to a brush roller cleaning machine. Background Technology

[0002] After rolling, metal foil often has residual oil and metal particles on its surface, requiring cleaning. Existing metal foil cleaning equipment includes spray cleaning, immersion cleaning, and brush roller cleaning. Among these, brush roller cleaning, which combines mechanical cleaning and spray cleaning, provides the best cleaning effect and can thoroughly remove oil and metal particles from the surface of the metal foil. Therefore, brush roller cleaning machines are often used for the final surface cleaning of copper and aluminum foil used in lithium batteries.

[0003] The principle of brush roller cleaning is that the metal foil moves through two pairs of opposing rotating back rollers and brush rollers. The back rollers support one side of the metal foil surface, while the brush rollers rotate at high speed, rubbing the other side of the metal foil surface. Combined with a spray of cleaning liquid, this cleans both sides of the metal foil. After brush roller cleaning, the surface of the metal foil becomes shiny due to the friction from the brush rollers. However, after brush roller surface cleaning, longitudinal bright and dark surface defects often appear near one edge. The reason for this is that during the rolling process, residual stress often exists due to edge tightness. This residual stress causes wavy deformation near the edge of the metal foil. This wavy deformation causes changes in the pressure exerted by the brush rollers on the metal foil surface during cleaning, resulting in longitudinal bright and dark surface defects after cleaning. Since the root cause of this defect is the residual rolling stress in the metal foil, existing metal foil brush roller cleaning machines cannot solve this problem. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model discloses a brush roller cleaning machine, which solves the quality defect of longitudinal bright and dark alternation on the surface of existing metal foil after being cleaned by the brush roller cleaning machine.

[0005] To achieve the aforementioned utility model objective, the present utility model adopts the following technical solution: a brush roller cleaning machine, comprising a frame and several sets of cleaning roller pairs arranged within the frame, the several sets of cleaning roller pairs being sequentially arranged along the feeding direction of the metal foil; a brush roller and a back roller are arranged in the center of each cleaning roller pair in a manner of upper and lower contact and rotation; when the brush roller cleaning machine is working, the metal foil passes sequentially through the contact surface between the brush roller and the back roller in the center of the several sets of cleaning roller pairs, the back roller supports the metal foil, and the brush roller cleans the surface of the metal foil; before the brush roller cleaning machine is working, the angle between the projection of the lower brush roller in the center of the cleaning roller pair relative to the axis of the upper back roller on the horizontal plane is adjusted; or the angle between the projection of the lower back roller in the center of the cleaning roller pair relative to the axis of the upper brush roller on the horizontal plane is adjusted, so that when the metal foil passes through the cleaning roller pair, a lateral driving force perpendicular to the feeding direction of the metal foil is generated.

[0006] Furthermore, the brush roller or back roller centered on the upper side of the cleaning roller alignment is mounted on the upper part of the frame via guide rails and sliders; the brush roller or back roller centered on the lower side of the cleaning roller alignment is mounted on the lower part of the frame via an angle adjustment assembly and a lower roller support block; the brush roller or back roller centered on the lower side of the cleaning roller alignment adjusts the angle between itself and the projection of the axis of the upper back roller or brush roller onto the horizontal plane via the angle adjustment assembly and the lower roller support block.

[0007] Furthermore, the lower roller support block is fixedly installed on the lower part of both sides of the frame; the upper surface of the lower roller support block is provided with an angle adjustment component support groove; the brush roller or back roller is provided with a lower bearing seat at both ends, the angle adjustment component is fixedly installed at the lower part of the lower bearing seat, and the angle adjustment component is installed in the angle adjustment component support groove of the lower roller support block. In the initial state, there is a gap of 2.0-3.0mm between the side of the angle adjustment component and the opposite side of the angle adjustment component support groove.

[0008] Furthermore, the included angle adjustment assembly includes an adjustment base and an adjustment slider. The upper end face of the adjustment base is symmetrically provided with two wedge grooves. The adjustment slider is provided with a slider wedge surface and a slider contact surface. The adjustment slider is movably set in the wedge groove, and the slider wedge surface and the wedge surface of the wedge groove abut against each other. In the initial state, there is a gap of 2.0-3.0mm between the slider contact surface and the opposite side of the support groove of the included angle adjustment assembly. The included angle adjustment assembly is also provided with a slider adjustment bolt corresponding to the adjustment slider. When the slider adjustment bolt is rotated, the adjustment slider is pushed to slide along the slider wedge surface, so that the slider contact surface moves outward and abuts against the opposite side of the support groove of the included angle adjustment assembly.

[0009] Furthermore, the included angle adjustment assembly is also equipped with a slider return spring.

[0010] Furthermore, it also includes an outer casing; the outer casing is fixedly mounted on the frame, and the brush roller and back roller are rotatably mounted inside the outer casing.

[0011] Furthermore, it also includes a spray cleaning component, which is fixedly installed on the side opposite the cleaning roller; when the brush roller cleaning machine is working, the spray cleaning component sprays cleaning liquid onto the metal foil.

[0012] Furthermore, the cleaning roller pair also includes a lifting control component, which controls the brush roller or back roller located on the upper side of the cleaning roller pair to move up and down.

[0013] Due to the adoption of the above-described technical solution, this utility model has the following beneficial effects: The brush roller cleaning machine disclosed in this utility model includes a frame and several sets of cleaning roller pairs arranged in the frame. The several sets of cleaning roller pairs are arranged adjacent to each other according to the feeding direction of the metal foil. A brush roller and a back roller are arranged in the middle of the cleaning roller pair to abut and rotate. The brush roller or back roller located on the lower side is arranged in the lower part of the frame through an angle adjustment component and a lower roller support block. Before the brush roller cleaning machine is working, the lower brush roller or back roller in the middle of the cleaning roller pair is adjusted by the angle adjustment component so that it makes an angle with the projection of the axis of the upper back roller or brush roller on the horizontal plane. This causes the metal foil to generate a lateral driving force perpendicular to the feeding direction of the metal foil when it passes through the cleaning roller pair. This lateral driving force will flatten the wavy deformation of the metal foil near the edge, thereby improving the uniformity of the pressure of the brush roller on the surface of the metal foil, thereby improving or solving the longitudinal bright and dark surface defects of the metal foil after being cleaned by the brush roller cleaning machine.

Angle adjustment component 2.2.4 is fixedly installed at the lower end of the lower bearing seat 2.2.2. Angle adjustment component 2.2.4 is installed in the angle adjustment component support groove 1.4.1 of the lower roller support block 1.4. In the initial state, there is a gap of 2.0-3.0mm between the two sides of the angle adjustment component 2.2.4 and the adjacent side of the angle adjustment component support groove 1.4.1. This gap is reserved space for the offset adjustment of the angle adjustment component 2.2.4 in the angle adjustment component support groove 1.4.1. See the instruction manual appendix Figure 8 The included angle adjustment assembly 2.2.4 includes an adjustment base 2.2.4.1, an adjustment slider 2.2.4.2, a slider return spring 2.2.4.3, and a slider adjustment bolt 2.2.4.4; see the appendix of the instruction manual. Figure 12 Adjust the base 2.2.4.1 to a rectangular block shape, with two symmetrical wedge grooves 2.2.4.1.1 on the upper end surface; see the instruction manual appendix. Figure 11 Adjust slider 2.2.4.2 to be wedge-shaped, with a slider wedge surface 2.2.4.2.1 on one side and an arc-shaped slider contact surface 2.2.4.2.2 opposite to the slider wedge surface 2.2.4.2.1; see the instruction manual appendix. Figure 8 Adjusting slider 2.2.4.2 is movable within wedge groove 2.2.4.1.1, with the slider wedge surface 2.2.4.2.1 abutting against the wedge surface of wedge groove 2.2.4.1.1; slider adjusting bolt 2.2.4.4 is mounted on adjusting base 2.2.4.1 through a bolt hole in adjusting base 2.2.4.1, with its end abutting against the large end of adjusting slider 2.2.4.2; slider return spring 2.2.4.3 is located at the small end of adjusting slider 2.2.4.2, with one end abutting against the small end wall of wedge groove 2.2.4.1.1 and the other end abutting against the small end of adjusting slider 2.2.4.2; see the appendix of the instruction manual. Figure 6 , 710: Angle adjustment component 2.2.4 is fixedly mounted on the lower end of the lower bearing seat 2.2.2 by bolts. Angle adjustment component 2.2.4 is located in the angle adjustment component support groove 1.4.1 of the lower roller support block 1.4. In the initial state, there is a gap of 2.0-3.0mm between the slider contact surface 2.2.4.2.2 and the opposite side of the angle adjustment component support groove 1.4.1, which is reserved for the adjustment space of the angle adjustment component 2.2.4 in the angle adjustment component support groove 1.4.1. Rotate the slider adjustment bolt 2 clockwise. When 2.4.4 is executed, the adjusting slider 2.2.4.2 is pushed to slide along the slider wedge surface 2.2.4.2.1, causing the slider contact surface 2.2.4.2.2 to move outward and contact the opposite side of the angle adjustment component support groove 1.4.1. When both adjusting sliders 2.2.4.2 are adjusted synchronously, the slider contact surfaces 2.2.4.2.2 of both adjusting sliders 2.2.4.2 move outward synchronously and contact the opposite side of the angle adjustment component support groove 1.4.1. Then, the angle adjustment component 2.2.4 is positioned within the angle adjustment component support groove 1.4. In section 2.1, the back roller 2.2.3 and the brush roller 2.1.4 are centered, and their axes are projected onto the horizontal plane. When the two adjusting sliders 2.2.4.2 are adjusted asynchronously, the sliding contact surfaces 2.2.4.2.2 of the two adjusting sliders 2.2.4.2 move outward by unequal distances. After the sliding contact surfaces 2.2.4.2.2 and the angle adjustment component support groove 1.4.1 fully contact each other on the opposite side, the angle adjustment component 2.2.4 is in an offset position in the width direction of the angle adjustment component support groove 1.4.1. When the back roller assembly 2. When the two angle adjustment components 2.2.4 in section 2 are both in the offset position in the angle adjustment component support groove 1.4.1 and the offset directions are opposite, the axis of the back roller 2.2.3 is deflected in the horizontal plane, and the projection of the axes of the back roller 2.2.3 and the brush roller 2.1.4 in the horizontal plane produces an angle; the arc-shaped design of the slider contact surface 2.2.4.2.2 ensures that the adjustment slider 2.2.4.2 can reliably contact the side wall of the angle adjustment component support groove 1.4.1 in any state after the offset adjustment of the angle adjustment component 2.2.4. See the instruction manual appendix Figure 13The lifting control component 2.3 includes a lifting drive component 2.3.1, a lifting synchronous shaft 2.3.2, and a lifting drive motor 2.3.3. Two lifting drive components 2.3.1 are provided, one of which is connected to the lifting drive motor 2.3.3. The two lifting drive components 2.3.1 are connected to each other via the lifting synchronous shaft 2.3.2. A lifting connecting rod 2.3.1.1 is provided at the lower part of the lifting drive component 2.3.1. The lifting control component 2.3 is fixedly installed on the upper horizontal plate 1.3 of the frame 1. The lower end of the lifting connecting rod 2.3.1.1 is fixedly connected to the lifting beam 2.1.1 in the brush roller assembly 2.1. When the lifting drive motor 2.3.3 drives the lifting drive component 2.3.1, the lifting connecting rod 2.3.1.1 moves up and down, thereby driving the brush roller assembly 2.1 to move up and down. After the brush roller assembly 2.1 is adjusted to the correct position, its position is locked by a locking device. The structure of cleaning roller pair B3 is basically the same as that of cleaning roller pair A2. The difference between cleaning roller pair B3 and cleaning roller pair A2 is that in cleaning roller pair B3, the back roller 2.2.3 is located at the upper part and the brush roller 2.1.4 is located at the lower part. When the lifting drive motor 2.3.3 drives the lifting drive assembly 2.3.1 to work, the lifting linkage 2.3.1.1 moves up and down, thereby driving the back roller 2.2.3 to move up and down. When the two angle adjustment assemblies 2.2.4 are both in the offset position in the angle adjustment assembly support groove 1.4.1 and the offset directions are opposite, the axis of brush roller 2.1.4 is deflected in the horizontal plane, and the axes of brush roller 2.1.4 and back roller 2.2.3 are projected into an angle in the horizontal plane. See the instruction manual appendix Figure 14 , 15 The brush roller cleaning machine also includes an outer casing 4; the outer casing 4 is fixedly mounted on the frame 1, and the brush roller 2.1.4 and back roller 2.2.3 are rotatably mounted in the outer casing 4 to prevent the cleaning liquid from splashing to the outside of the outer casing 4 and polluting the working environment when the brush roller cleaning machine is working. See the instruction manual appendix Figure 5 The brush roller cleaning machine also includes a spray cleaning component 5, which is fixedly installed in the outer casing 4. When the brush roller cleaning machine is working, the spray cleaning component 5 sprays cleaning liquid onto the metal foil to wash away the oil and metal particles on the surface of the metal foil 6.

[0018] See the instruction manual appendix Figure 16Ideally, the metal foil 6 has no residual stress and its surface is flat. During operation, the back roller 2.2.3 and brush roller 2.1.4 are aligned so that their projections in the horizontal plane coincide. The back roller 2.2.3 rotates synchronously with the metal foil 6 feed speed to prevent relative sliding between them due to speed differences, thus avoiding scratches on the metal foil 6 surface. The metal foil 6 passes through two sets of cleaning... The contact surface between the brush roller 2.1.4 and the back roller 2.2.3 in the roller pair, the back roller 2.2.3 supports the metal foil 6, and the metal foil 6 presents a certain wrapping angle on the surface of the back roller 2.2.3; the brush roller 2.1.4 rotates at high speed to perform friction cleaning on the surface of the metal foil, and the spray cleaning component 5 sprays cleaning liquid onto the metal foil to wash away the oil and metal particles on the surface of the metal foil 6; after the metal foil 6 passes through the two sets of cleaning roller pairs in sequence, the cleaning of the upper and lower surfaces of the metal foil 6 is completed.

[0019] See the instruction manual appendix Figure 17 In most cases, residual stress exists in the metal foil 6. As shown in the attached figure, there is a residual stress zone 6.1 of a certain width on the right side of the metal foil 6, and the surface of the metal foil in this area is wavy. In this case, it is necessary to make asynchronous adjustments to the adjusting sliders 2.2.4.2 in the two angle adjustment components 2.2.4 of the cleaning roller centering, so that the axis of the back roller 2.2.3 or brush roller 2.1.4 located at the lower part of the cleaning roller centering is deflected in the horizontal plane, so that the axes of the same cleaning roller centering brush roller 2.1.4 and back roller 2.2.3 project into an angle in the horizontal plane. Then, the position of the back roller 2.2.3 or brush roller 2.1.4 is locked by a locking device. See attached figure for details. Figure 17 As shown, when there is a residual stress zone 6.1 on the right side of the metal foil 6, the back roller 2.2.3 or the brush roller 2.1.4 located on the lower side deflects clockwise, and the intersection of the projections of the axes of the back roller 2.2.3 and the brush roller 2.1.4 in the horizontal plane is located within the residual stress zone 6.1 of the metal foil 6. At this time, when the metal foil 6 passes through the contact surface between the brush roller 2.1.4 and the back roller 2.2.3 of the two sets of cleaning rollers in sequence, a lateral driving force to the right will be generated. This lateral driving force is largest near the intersection of the projections of the axes of the back roller 2.2.3 and the brush roller 2.1.4 in the horizontal plane in the same cleaning roller pair. This lateral driving force will flatten the wavy deformation on the right side of the metal foil 6, thereby improving the uniformity of the pressure exerted by the brush roller 2.1.4 on the surface of the metal foil, thus improving or solving the longitudinal bright and dark surface defects of the metal foil 6 after cleaning by the brush roller cleaning machine.
