Description

Technical Field

[0001] This utility model relates to a roller scraper fixing device for lithium battery production, belonging to the field of lithium battery production technology. Background Technology

[0002] In the negative electrode rolling process of lithium battery production, graphite powder easily adheres to the roller surface due to the physicochemical properties of the negative electrode sheet. This graphite powder adhesion severely affects the quality of the electrode sheet, causing surface defects and reducing the yield rate of lithium battery production. To solve this problem, existing technologies typically use resin scrapers to clean the roller surface to remove the adhered graphite powder, thereby ensuring the quality of the electrode sheet.

[0003] However, most resin doctor blades currently in use are disposable consumables with a short service life. During the rolling process, the blade edges wear down easily due to continuous friction with the rollers, requiring complete replacement once damaged. This usage leads to a huge consumption of resin doctor blades and a high replacement frequency, which not only increases the production cost of lithium batteries but also affects production efficiency.

[0004] Therefore, it is urgent to improve the existing roller scraper fixing device to extend the service life of the resin scraper, reduce the number of replacements, thereby reducing production costs and improving the production efficiency of lithium batteries. Utility Model Content

[0005] To address the problems existing in the background technology, this utility model provides a roller scraper fixing device for lithium battery production.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a roller scraper fixing device for lithium battery production, comprising screws, a front fixing plate, a rear fixing plate, and positioning bolts; the rear fixing plate is fixedly connected to the front fixing plate by at least one screw, and positioning bolts are fixed on both the left and right sides of the front end of the rear fixing plate.

[0007] Both the front and rear fixing plates are made of mold steel.

[0008] The number of positioning pins is at least one. When the number of positioning pins is greater than one, the positioning pins are evenly distributed along the width direction of the resin scraper.

[0009] The positioning bolt is integrally formed with the rear fixing plate.

[0010] The positioning bolts on the left and right sides of the rear fixing plate are set one-to-one.

[0011] The positioning bolt is one or more of the following: a cylindrical, elliptical, or square cylinder.

[0012] An adjusting shim is installed between the front fixing plate and / or the rear fixing plate and the resin scraper.

[0013] The adjustment shims are designed to be detachable.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention achieves precise positioning and cyclic use of the scraper after repair by cooperating with the positioning bolts and the pre-set positioning holes of the scraper, extending the service life of the resin scraper and significantly reducing the cost of scraper consumables. The fixing plate is made of high-strength mold steel and equipped with detachable adjusting shims, ensuring both the overall structural strength and wear resistance of the device. Furthermore, the shim thickness allows for fine adjustment of the scraper's installation height and angle, ensuring good contact pressure between the scraper and the roller. In addition, the evenly distributed positioning bolts along the width of the scraper and the adaptability to various column shapes effectively improve the stability of the scraper installation, preventing displacement or loosening during operation, ensuring effective graphite powder removal, and thus improving the yield rate of lithium battery electrode production.

[0020] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0021] A roller scraper fixing device for lithium battery production includes a screw 1, a front fixing plate 2, a rear fixing plate 3, and positioning bolts 5. The rear fixing plate 3 is fixedly connected to the front fixing plate 2 by at least one screw 1, and the screw 1 clamps and fixes the resin scraper 4 between the front fixing plate 2 and the rear fixing plate 3. Positioning bolts 5 are fixed on both the left and right sides of the front end of the rear fixing plate 3, and the positioning bolts 5 are inserted into the positioning holes on the left and right sides of the resin scraper 4 respectively.

[0022] Before use, the resin scraper 4 has multiple positioning holes with a spacing of 5mm on both the left and right sides using a drilling machine. The positioning holes are then inserted into the positioning bolts 5.

[0023] When the cutting edge of the resin scraper 4 is damaged, it is repaired by cutting off 5mm and then reinstalled. This process is repeated. After each repair, the uppermost positioning hole is moved down one position on the positioning bolt, thereby increasing the lifespan of the resin scraper 4 by N times.

[0024] Both the front fixing plate 2 and the rear fixing plate 3 are made of mold steel (SK4), which has high strength and wear resistance.

[0025] The number of positioning bolts 5 is at least one. When the number of positioning bolts 5 is greater than one, the positioning bolts 5 are evenly distributed along the width direction of the resin scraper 4.

[0026] The positioning bolt 5 is integrally formed with the rear fixing plate 3 to enhance the stability of the overall structure.

[0027] The positioning bolts 5 on the left and right sides of the rear fixing plate 3 are set one-to-one to achieve precise positioning of the scraper.

[0028] The positioning bolt 5 is one or more of a cylindrical, elliptical, or square cylinder.

[0029] Adjusting shims are installed between the front fixing plate 2 and / or the rear fixing plate 3 and the resin scraper 4 to adjust the installation height and / or angle of the resin scraper 4, ensuring good contact between the resin scraper 4 and the roller.

[0030] The adjustment shims are detachable, and shims of different thicknesses can be selected as needed to achieve fine adjustment of the scraper installation height and / or angle.
