Description

Technical Field

[0001] The present application relates to the technical field of lithium battery roller presses, and in particular to a roller surface quick disassembly and assembly scraper device. Background Art

[0002] In the production of lithium batteries, the rolling process of lithium battery pole pieces is a crucial link. However, in this process, the material coated on the pole piece often leaves residues on the roller surface of the roller press due to the effect of adhesion. If these residues are not handled in time, it will have a serious impact on the surface quality of the pole piece, and may cause quality problems such as pits and cracks, thereby affecting the performance and safety of the battery.

[0003] The existing roller scraper is generally installed near the roller and a dust suction device is arranged underneath to clean the residue left by the scraper. The scraper will be constantly worn after being in contact with the roller. Over time, the scraper will not be able to stick to the roller surface and cannot perform the cleaning function. The scraper needs to be replaced manually in time to ensure that the scraper can work normally. At this time, a scraper structure with a more convenient and simple replacement process is needed. Secondly, the material cleaned by the scraper is easily accumulated in the vacuum box and is difficult to be sucked away by the negative pressure. Excessive accumulation leads to a weakening or even loss of the negative pressure function. Utility Model Content

[0028] A roller surface quick disassembly and assembly scraper device comprises a fixed side plate 4 mounted on a roller press 1, a dust removal device 3, an adjustment device mounted on the fixed side plate 4, and a scraper device 2, wherein the scraper device 2 is mounted on the fixed side plate 4 through the adjustment device; in this embodiment, both ends of the roller surface are provided with a fixed side plate 4, and the two fixed side plates 4 are provided with an adjustment device,

[0029] The scraper device 2 includes an airbag base 20, a scraper pressure plate 22, a scraper 24, a spring pressure plate 23, a guide screw 21, a compression spring 25, a push plate 26, and an airbag 27; both ends of the airbag base 20 are connected to the adjustment device respectively, a chamber 29 and a screw hole for the guide screw 21 to pass through are provided in the airbag base 20, the screw hole is connected to the chamber 29, the push plate 26 and the airbag 27 are located in the chamber 29, the side of the chamber 29 away from the screw hole is covered by the bottom sealing plate 28, and the airbag 27 is located between the bottom sealing plate 28 and the push plate 26; the end of the guide screw 21 is sequentially penetrated by the scraper pressure plate 22 and the spring pressure plate 23, penetrated by the screw hole and embedded in the chamber 29, and fixed with the push plate 26, the compression spring 25 is sleeved on the guide screw 2 1, the compression spring 25 is in a compressed state, one end of the compression spring 25 is fixed to the push plate 26, and the other end is against the spring pressure plate 23; due to the elastic force of the compression spring 25, the push plate 26 pulls the guide screw 21 toward the direction of the chamber 29, so that the scraper 24 is pressed against the airbag base 20 by the scraper pressure plate 22, and the installation of the scraper 24 is realized. When the scraper 24 needs to be removed, the airbag 27 is inflated to push the push plate 26 toward the direction of the scraper 24, so that the guide screw 21 moves outward, and the scraper pressure plate 22 is separated from the airbag base 20. At this time, the scraper 24 can be easily taken out, the operation is simple, convenient and fast, which greatly reduces the time and operation steps for replacing the scraper 24 and improves the production efficiency.

The spiral brush is connected to a brushless motor, and the brushless motor drives the spiral brush to rotate to remove dust adsorbed on the inner wall of the dust suction duct 31 to avoid dust accumulation.

[0031] The roller surface can be quickly disassembled and assembled with the scraper device. When the airbag 27 is not inflated, the scraper 24 is pressed against the airbag base 20 by the scraper pressure plate 22 under the action of the compression spring 25. When the scraper 24 needs to be removed, it is only necessary to inflate the airbag 27, the airbag 27 expands, pushes the push plate 26 to compress the compression spring 25, and moves the guide screw 21 outward, thereby separating the scraper pressure plate 22 from the airbag base 20, and the scraper 24 can be removed. When the scraper 24 needs to be installed, it is only necessary to place the scraper 24 between the scraper pressure plate 22 and the airbag base 20, and deflate the airbag 27 so that the scraper pressure plate 22 can press the scraper 24 against the airbag base 20; this combined design greatly improves the speed and portability of blade replacement and saves labor; at the same time, the dust removal device 3 is provided to collect dust dropped during the operation of the scraper 24, and the spiral brush therein can prevent dust from accumulating in the dust removal device 3, thereby achieving the effect of smoothly conveying dust.

By rotating the semicircular turntable 12 to rotate the rotating head, the airbag base 20 and the scraper 24 are driven to rotate at the same time, so as to adjust the angle of the scraper 24. After the angle of the scraper 24 is adjusted, the cylinder 11 is driven to retract and retract, so that the action rod of the cylinder 11 is inserted into the positioning hole 14, thereby fixing the position of the rotating rod 13 so that it cannot continue to rotate, thereby positioning the scraper 24. When the angle of the scraper 24 needs to be adjusted, the cylinder 11 is retracted, and the action rod of the cylinder 11 is moved out of the positioning hole 14 to rotate the rod 13 to adjust the angle of the scraper 24. At the same time, when the scraper 24 needs to be replaced, it only needs to retract the cylinder 11 to release the lock, and then the airbag base 20 is easily rotated to facilitate the replacement of the scraper 24.

[0035] In the utility model, the dust removal device 3 includes a fixed bracket 30, a dust suction duct 31 is installed on the fixed bracket 30, the fixed bracket 30 is connected to the roller press 1, and a negative pressure is set in the dust suction duct 31.
