Description

Technical Field

[0001] This utility model relates to the field of battery electrode production, and in particular to a roller brush dust removal device. Background Technology

[0002] After the battery electrodes are cut, they need to pass through a roller brush dust removal device to brush the dust off the front and back surfaces of the battery electrodes. The conventional roller brush dust removal device works by having the roller brush contact the surface of the electrode, and the roller brush removes the dust from the surface of the electrode. After the dust removal is completed, the dust is sucked away by negative pressure.

[0003] However, the debris generated after dust removal is divided into large-diameter debris and small-diameter debris. Large-diameter debris will accumulate in the negative pressure channel, which will reduce the flow of negative pressure over time, thus affecting the dust removal effect on the battery electrode.

[0004] In summary, how to prevent large-diameter debris from clogging the negative pressure channel during the dust removal process of roller brushes has become an urgent problem for researchers in this field. Utility Model Content

[0005] The technical problem to be solved by this utility model is: how to prevent large-diameter fragments from clogging the negative pressure channel during the dust removal process of roller brushes;

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] This utility model is a roller brush dust removal device, comprising: two opposing roller brush boxes, each containing a rotatable roller brush; windows on opposite sides of the two roller brush boxes, with the roller brush portion located outside the corresponding windows; a dust collection box fixed to the bottom of the roller brush box and connected to it; a dust collection pipe fixed to the bottom of the dust collection box and connected to it; a slide rail disposed at both ends of the roller brush box, with the bottom of the roller brush box slidably mounted on the slide rail; a cylinder driving the two roller brush boxes closer to or further away; and a horizontal filter screen retractable along the roller brush axis between the dust collection box and the roller brushes. When the cylinder is activated, the two roller brush boxes are moved along the slide rail, bringing the two roller brushes closer to the battery electrode for dust removal. Small-diameter debris falls from the filter screen's pores into the dust collection box and is sucked away by the dust collection pipe, while large-diameter debris remains on the filter screen's pores. The large-diameter debris is then processed after the filter screen is pulled out.

[0008] Furthermore, a handle is provided on one side of the filter screen, and this side is flush with the side wall of the roller brush box.

[0009] Furthermore, the bottom of the roller brush box extends to both sides with extension plates, and the bottom of the extension plates is provided with sliders that cooperate with the slide rail.

[0010] Furthermore, a connector is fixed to the bottom of the extension plate, the output end of the cylinder is connected to the connector, and the cylinder body is connected to the fixed base.

[0011] Furthermore, a limiting component is fixed at the bottom of the extension plate; and stop components are provided in the middle and on both sides of the slide rail.

[0012] When the limiting member contacts the stopping member, the roller brush box moves to its limit position.

[0013] Furthermore, a support rod is provided between the filter screen and the roller brush. The support rod is parallel to the axis of the roller brush and has a paddle on it that abuts against the roller brush. A paddle angle adjustment rod is provided at the end of the support rod located on the side wall of the roller brush box. By rotating the paddle angle adjustment rod, the contact angle between the paddle and the roller brush is adjusted.

[0014] The beneficial effects of this utility model are as follows: This utility model is a roller brush dust removal device. The filter screen has multiple filter holes, which allow small-diameter debris to pass through. When this device is working, large-diameter debris is retained on the filter holes. By periodically removing the filter screen and centrally processing the large-diameter debris, it can be reinstalled between the roller brush and the dust collection box. This can prevent large-diameter debris from falling from the dust collection box into the dust collection pipe and causing blockage. After the large-diameter debris is removed, the dust and tiny particles on the battery electrode sheets can be better removed, ensuring the quality of the electrode sheets.

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0016] Figure 1 This is a schematic diagram of a roller brush dust removal device.

[0017] Figure 2 A schematic diagram of the bottom structure of the roller brush dust collector;

[0018] Figure 3 This is a cross-sectional view of the roller brush box;

[0019] Figure 4 This is a schematic diagram of the filter screen structure;

[0020] Figure 5 This is a diagram showing the connection between the roller brush, rotating rod, and paddle. Detailed Implementation

[0021] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0022] See Figure 1 , Figure 1This is a schematic diagram of the roller brush dust removal device. In the figure, two roller brush boxes 1 are arranged opposite each other. Roller brushes 2 are installed inside the roller brush boxes. The roller brushes 2 are controlled to rotate by the motors 3 corresponding to the ends of the roller brushes 2. Windows 11 are provided on the opposite sides of the two roller brush boxes 1. Part of the roller brushes 2 protrudes out of the windows 11. A dust collection box 4 is provided at the bottom of the roller brush box 1. A dust collection pipe 5 is provided at the bottom of the dust collection box 4.

[0023] The roller brush box 1 has an extension plate 12 at the bottom, and a slider (not shown) is provided at the bottom of the extension plate 12. The slider is slidably mounted on the slide rail 6. A corrugated pipe 61 is provided between the end of the slide rail 6 and the extension plate 12, and between the two extension plates 12. The function of the corrugated pipe 61 is to prevent dust from contaminating the slide rail 6 and causing the roller brush box 1 to jam when moving.

[0024] See Figure 2 , Figure 2 This is a schematic diagram of the bottom structure of the roller brush dust removal device. There are 4 cylinders 7. One end of the cylinder 7 is connected to the fixed base 71, and the other end is connected to the connector 72 at the bottom of the extension plate 12.

[0025] In summary, when the battery electrode needs to be dusted, the output end of the cylinder 7 extends through the space between the two roller brush boxes 1, and the distance between the two roller brush boxes 1 is adjusted until the roller brush 2 contacts the battery electrode. The motor 3 controls the roller brush to rotate, brushing away the debris on the battery electrode. The brushed debris falls into the dust collection box 4 and is sucked away by the negative pressure of the dust collection pipe 5.

[0026] See Figure 3 , Figure 3 This is a cross-sectional view of the roller brush box. In the figure, a horizontal filter screen 8 is set between the roller brush 2 and the dust collection box 4 inside the roller brush box 1. The filter screen 8 is set to be pulled out along the roller brush axis. A handle 81 is set on the left side of the filter screen 8. The handle 81 is located outside the roller brush box 1, so that the handle 81 can be pulled to pull the filter screen 8 out of the roller brush box 1.

[0027] See Figure 4 , Figure 4 This is a schematic diagram of the filter screen. The filter screen 8 in the figure is a rectangular structure. A handle 81 is connected to the left side of the filter screen 8. The filter screen 8 has multiple filter holes 82. Small-diameter debris can pass through the filter holes 82, while large-diameter debris is retained on the filter holes 82. In this way, the filter screen 8 is periodically removed, and the large-diameter debris is centrally processed before being reinstalled between the roller brush 2 and the dust collection box 4. This can prevent large-diameter debris from falling from the dust collection box 4 into the dust collection pipe 5 and causing blockage of the dust collection pipe 5.

[0028] In some possible embodiments, see Figure 1 The bottom of the extension plate 12 is fixed with a limiting member 13; the middle and both sides of the slide rail 6 are provided with stop members 14; when the limiting member 13 contacts the stop member 14, the roller brush box 1 moves to the limit position.

[0029] This limits the stroke of the roller brush box 1, preventing damage to the battery electrode sheets from excessively small distances between the two roller brush boxes 1, and preventing the slider from disengaging from the slide rail from excessively large distances between the two roller brush boxes 1.

[0030] In some possible embodiments, see Figure 5 In the figure, support rod 9 is located below roller brush 2. A lever 91 is installed on support rod 9 to contact the outer wall of roller brush 2. A lever angle adjustment rod 92 is installed at the end of support rod 9, located on the side wall of roller brush box 1 (see figure). Figure 1 Rotate the angle adjustment lever 92 to adjust the adhesion force of the lever 91 on the roller brush, and scrape off the debris on the roller brush 1.

[0031] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
