Description

Technical Field

[0001] The utility model relates to the technical field of roller pressing, in particular to a scraper device which can improve the content of magnetic substances in a roller pressing machine. Background Art

[0002] Battery pole pieces refer to thin metal plates in secondary batteries and battery packs, which are used to make positive and negative electrodes. When producing pole pieces, the raw materials need to be put into a roller press for rolling so that the thickness of the raw materials is reduced to the thickness of the battery pole piece before subsequent processing. After the roller press has been working for a long time, some impurities (such as dust or raw material debris) will stick to the surface of the roller. In order to ensure the rolling effect, a scraper device is usually installed on the roller press to scrape impurities on the surface of the roller. Because the scraper will contact and rub with the surface of the roller during the scraping work, the chrome plating on the surface of the roller and the iron-containing scraper will be worn to a certain extent, resulting in fine granular magnetic substances such as Cr (chromium) and Fe (iron) that easily fall on the pole piece, causing magnetic substances such as Cr and Fe to adhere to the surface of the pole piece, reducing battery performance. Utility Model Content

[0003] To this end, the purpose of the utility model is to provide a scraper device that can improve the content of magnetic materials in a roller press, so as to solve the technical problem that when a traditional scraper device cleans the rollers of a roller press, magnetic materials such as Cr and Fe generated by friction are easily attached to the surface of the pole piece, thereby reducing the performance of the battery.

[0004] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: to provide a scraper device capable of improving the content of magnetic substances in a roller press, and the scraper device capable of improving the content of magnetic substances in a roller press comprises:

[0005] A frame, with both ends of the roller rotatably connected to the frame;

[0006] A baffle, both ends of which are slidably fitted on the frame, and a groove is provided in the middle of the baffle;

[0007] A scraper, the scraper is fixed on the baffle, and the groove and the scraper form a funnel-shaped receiving area for receiving scraped objects;

[0008] A scraper adjustment part, the scraper adjustment part is arranged on the frame, and the scraper adjustment part is used to adjust the force between the scraper and the roller;

[0009] The dust suction part includes a dust suction pipe and a dust collector. One end of the dust suction pipe is fixed to the baffle and communicated with the interior of the storage area, and the other end of the dust suction pipe is connected to the dust collector.

[0010] In one embodiment, the nozzle of the dust suction pipe on the baffle is located at the bottom of the storage area and faces the blade of the scraper.

[0011] In one embodiment, the dust suction pipe is a hose.

[0012] In one embodiment, the scraper adjustment unit includes:

[0013] An adjustment plate, the adjustment plate is fixed on the frame, and the adjustment plate has four threaded holes equidistantly distributed;

[0014] Four adjusting screws, each of which is matched with the threaded holes of the adjusting plate, and one end of each adjusting screw is against the baffle;

[0015] A resilient member is disposed between the frame and the baffle plate, and the resilient member applies an elastic force to the baffle plate in a direction away from the roller.

[0016] In one embodiment, the other end of the adjusting screw is provided with a handle for facilitating manual adjustment.

[0017] In one embodiment, the scraper is made of wear-resistant metal material.

[0018] One or more of the above technical solutions in the embodiments of the present utility model have at least the following technical effects or advantages:

[0019] The scraper device provided by the embodiment of the utility model can improve the content of magnetic materials in the roller press. The scraper is fixed on the baffle plate and a groove is set on the baffle plate, so that the groove and the scraper form a funnel-shaped storage area that can store scraped materials (including magnetic materials such as Cr, Fe and other impurities), so as to prevent the scraped materials from directly falling down to the surface of the pole piece. And through the dust suction part, the vacuum suction is generated by the vacuum cleaner in the dust suction part, and the debris in the storage area and the magnetic materials such as Cr, Fe generated by the friction between the scraper and the roller are sucked away through the dust suction pipe (the entrance of the vacuum tube is set inside the storage area, but it will still generate suction to the friction area between the scraper and the roller), thereby greatly reducing the probability of magnetic materials such as Cr, Fe adhering to the surface of the pole piece to ensure battery performance.

[0020] In addition, by setting the scraper adjustment part, the force between the scraper and the roller can be manually adjusted. Under the premise of ensuring the scraping effect, the force between the scraper and the roller can be reduced as much as possible to reduce the friction between the two, thereby reducing the generation of magnetic substances such as Cr and Fe.

[0029] See also Figure 1 The embodiment of the present application provides a scraper 3 device that can improve the magnetic material content of a roller press, including a frame 1, a dust suction part 5, a baffle 2, a scraper 3, and a scraper adjustment part 4; wherein, both ends of the roller 6 are rotatably connected to the frame 1; both ends of the baffle 2 are slidably fitted on the frame 1, and a groove is provided in the middle of the baffle 2; the scraper 3 is fixed on the baffle 2, and the groove and the scraper 3 form a funnel-shaped receiving area for receiving scraped materials; the scraper adjustment part 4 is provided on the frame 1, and the scraper adjustment part 4 is used to adjust the force between the scraper 3 and the roller 6; the dust suction part 5 includes a dust suction pipe 51 and a dust collector 52, one end of the dust suction pipe 51 is fixed on the baffle 2 and communicated with the interior of the receiving area, and the other end of the dust suction pipe 51 is connected to the dust collector 52.

[0030] Optionally, the suction force generated by the vacuum cleaner 52 can be increased by increasing its output power, thereby improving the vacuuming effect of the vacuum cleaner 5, so that the magnetic substances such as Cr and Fe generated by the friction between the scraper 3 and the roller 6 can be basically sucked away and removed by the vacuum cleaner 5, so as to further reduce the risk of Cr and Fe adhering to the surface of the pole piece.

[0031] Optional, such as Figure 1 As described above, a plurality of dust suction pipes 51 may be provided, one end of the dust suction pipes 51 being evenly arranged in the storage area, and the other end being connected to the dust collector 52. By providing a plurality of dust suction pipes 51, the effective range of the dust suction part 5 is increased, and the dust suction effect is improved.

[0032] In one embodiment, the mouth of the dust suction pipe 51 on the baffle 2 is located at the bottom of the storage area and faces the blade position of the scraper 3. By setting the mouth of the dust suction pipe 51 at the bottom of the storage area, the dust suction pipe 51 can better absorb and remove the debris in the storage area. And by pointing the mouth of the dust suction pipe 51 toward the blade position of the scraper 3, the vacuum suction force in the dust suction pipe 51 can better act on the blade position of the scraper 3 (that is, the area where the scraper 3 and the roller 6 rub to produce magnetic substances such as Cr and Fe), so that the dust suction pipe 51 can promptly absorb and remove the magnetic substances such as Cr and Fe produced by the friction between the scraper 3 and the roller 6.

[0033] In one embodiment, the dust suction tube 51 is a hose, which can be a metal hose or a rubber or plastic hose. By setting the dust suction tube 51 as a hose, the scraper adjustment unit 4 can adjust the scraper 3, and the dust suction tube 51 can be prevented from hindering the adjustment of the scraper adjustment unit 4.

[0034] Since the conventional adjustment device only has adjustment screws at both ends of the scraper 3, the two ends of the scraper 3 device are subjected to force, and the positions corresponding to the force points of the scraper 3 and the roller 6 are more easily worn; and since the scraper 3 is long and there is no movable screw adjustment in the middle part, the scraper 3 is easy to bend and deform after long-term work. To this end, in one embodiment, the scraper adjustment part 4 includes a rebound member, four adjustment screws 42, and an adjustment plate 41. The adjustment plate 41 is fixed on the frame 1, and the adjustment plate 41 has four threaded holes distributed evenly; the adjustment screws 42 are respectively matched with the threaded holes of the adjustment plate 41, and one end of the adjustment screw 42 is against the baffle 2; the rebound member is arranged between the frame 1 and the baffle 2, and the rebound member gives the baffle 2 an elastic force away from the roller 6. By setting four adjustment screws 42 and equidistantly arranging the four adjustment screws 42 on the baffle 2, the four movable adjustment screws 42 are evenly distributed on the scraper 3, thereby ensuring that the scraper 3 is subjected to uniform force and reducing the wear rate of the scraper 3 and the roller 6.

[0035] In one embodiment, a handle for manual adjustment is provided at the other end of the adjusting screw 42. By providing the handle, the adjusting screw 42 can be manually rotated without using a tool, so as to adjust the scraper 3.

[0036] In one embodiment, the scraper 3 is made of wear-resistant metal material, specifically T8 steel or other materials.

[0037] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
