Description

Technical Field

[0001] The utility model relates to the technical field of diaphragm preparation, in particular to a slurry scraper device. Background Art

[0002] During the preparation of lithium battery separators, a coating is often applied to the separator surface to enhance its performance. Separator coating for lithium batteries can be achieved through spraying or roller coating. Roller coating involves applying a slurry to a mesh roller. When the mesh roller contacts the separator, the slurry is applied to the membrane.

[0003] like Figure 1 As shown, during the lithium battery separator coating process, the anilox roller 100 rotates counterclockwise, discharging the slurry from the slurry box 300. Under the pressure of the water-coating scraper 200 and the anilox roller 100, a uniform liquid surface is formed and coated on the separator, achieving uniform and effective coating. During the production process, slurry accumulation points 400 form on the contact surface between the anilox roller 100 and the water-coating scraper 200, affecting the coating effect. Currently, these accumulation points 400 must be manually scraped off on the anilox roller 100 on a regular basis. This method has the disadvantages of being easily missed and inefficient, resulting in poor separator coating results.

[0004] Therefore, a slurry scraper device is needed to solve the above problems. Utility Model Content

[0034] In the process of coating the surface of the lithium battery diaphragm, in order to effectively clean the slurry accumulation on the screen roller and ensure the effect of the diaphragm coating, such as Figures 1-4 As shown, the utility model provides a slurry scraper device. The slurry scraper device includes a linear travel component 1, a position adjustment component 2, a scraper component 3 and a slurry removal component 4.

[0035] The linear travel assembly 1 extends along a first direction. The position adjustment assembly 2 is in transmission connection with the linear travel assembly 1. The scraper assembly 3 is mounted on the position adjustment assembly 2 and can adjust the position of the scraper assembly 3. The linear travel assembly 1 can drive the position adjustment assembly 2 to move in the first direction, thereby causing the scraper assembly 3 to scrape the slurry accumulated on the screen roller 100 along the first direction. The slurry removal assembly 4 is mounted on the position adjustment assembly 2 and is used to remove waste slurry remaining on the scraper assembly 3. It should be noted that the first direction is parallel to the axial direction of the screen roller 100.

[0036] When cleaning the anilox roller 100, the position adjustment assembly 2 adjusts the position of the scraper assembly 3 so that the scraper assembly 3 contacts the surface of the anilox roller 100. The linear travel assembly 1 then drives the position adjustment assembly 2 to move in a first direction, causing the scraper assembly 3 to clean the anilox roller 100 along its axial direction. Finally, the slurry removal assembly 4 removes the waste slurry accumulated on the scraper assembly 3. This approach enables automated anilox roller cleaning, effectively removing slurry accumulations 400 on the anilox roller 100 and ensuring effective membrane coating.

[0037] In some embodiments, the linear motion assembly 1 includes a motor 11, a mounting seat 13, and a linear module 12 extending along a first direction. The motor 11 is in transmission connection with the linear module 12, and the position adjustment assembly 2 is disposed on the linear module 12 and is in transmission connection with the linear module 12. Specifically, the motor 11 can be a servo motor 11, the linear module 12 adopts a screw-nut structure, the mounting seat 13 is slidably disposed on the linear module 12, and the position adjustment assembly 2 is connected to the mounting seat 13. The linear module 12 is driven by the motor 11, and the linear module 12 drives the mounting seat 13 to move, thereby achieving movement of the position adjustment assembly 2. When cleaning the mesh roller 100, the scraper assembly 3 can be moved along the axial direction of the mesh roller 100 to ensure effective cleaning of the mesh roller 100. In other embodiments, a cylinder can be used instead of the linear motion assembly 1, and the position adjustment assembly 2 can be disposed on the piston rod of the cylinder. The mesh roller 100 can be cleaned by controlling the extension and retraction of the piston rod of the cylinder. No further restrictions are imposed here.

[0038] In some embodiments, the position adjustment assembly 2 includes a connecting base 21, a rotary drive 22, and a lifting drive 23. The connecting base 21 is in transmission connection with the linear travel assembly 1. The rotary drive 22 is fixedly mounted on the connecting base 21. The lifting drive 23 is connected to the output shaft of the rotary drive 22, and the scraper assembly 3 is connected to the output shaft of the lifting drive 23. Specifically, the connecting base 21 is mounted at the lower end of the mounting base 13. When the linear module 12 drives the mounting base 13 to move, the mounting base 13 simultaneously drives the connecting base 21 to move. The rotary drive 22 can adjust the inclination of the lifting drive 23, and the lifting drive can adjust the height of the scraper assembly 3. This allows for flexible adjustment of the inclination and height of the scraper assembly 3 according to the cleaning position of the net roll 100, achieving effective cleaning of the net roll 100. In this embodiment, the rotary drive 22 is a rotary cylinder, and the lifting drive 23 is a dual-axis cylinder. In other embodiments, the rotary drive 22 can be a motor, and the lifting drive 23 can be a linear motor, without further limitation. In this embodiment, the output shaft of the rotary drive member 22 is non-parallel to the first direction. More specifically, the output shaft of the rotary drive member 22 is perpendicular to the first direction. In other embodiments, the output shaft of the rotary drive member 22 is neither parallel nor perpendicular to the first direction, but rather forms a certain angle therewith. The output shaft of the lifting drive member 23 is perpendicular to the output shaft of the rotary drive member 22.

[0039] In some embodiments, the slurry scraper device further includes a floating connection assembly 5, which is disposed on the output shaft of the elevating drive 23. More specifically, the output shaft of the elevating drive 23 is provided with a fixed plate 231, and the floating connection assembly 5 is disposed on the fixed plate 231 of the elevating drive 23. The scraper assembly 3 is disposed on the floating connection assembly 5 and is capable of driving the scraper assembly 3 to rotate about a second direction. In this embodiment, the second direction is non-parallel to the output shaft of the elevating drive 23; more specifically, the second direction is perpendicular to the output shaft of the elevating drive 23. The provision of the floating connection assembly 5 enables the scraper assembly 3 to rotate relative to the fixed plate 231 within a certain angle, thereby adaptively adjusting the angle based on the contact position of the scraper assembly 3 with the screen roller 100, ensuring effective adhesion of the scraper assembly 3 to the screen roller 100 and subsequent cleaning effectiveness.

[0040] In some embodiments, the floating connection assembly 5 includes a first rotating shaft 52 and a connecting plate 51. The first rotating shaft 52 extends in the second direction and is fixedly mounted on the connecting plate 51. The first rotating shaft 52 is rotatably mounted on the fixed plate 231 of the lifting drive 23 in the second direction. The scraper assembly 3 is mounted on the connecting plate 51. The first rotating shaft 52 and the fixed plate 231 rotate in the second direction, enabling fine adjustment of the angle of the scraper assembly 3 mounted on the connecting plate 51 relative to the screen roller 100, thereby ensuring the subsequent cleaning effect of the screen roller 100. To ensure smooth rotation of the first rotating shaft 52, a bearing is installed at the interface between the first rotating shaft 52 and the fixed plate 231. The bearing converts sliding friction into rolling friction, thereby ensuring smooth rotation of the first rotating shaft 52.

[0041] In some embodiments, a limiter 232 is fixedly mounted on the fixed plate 231 of the lifting drive 23. The limiter 232 is used to limit the rotation angle of the first rotating shaft 52 relative to the connecting plate 51. By providing the limiter 232, the connecting plate 51 can be constrained to rotate within a set range. In this embodiment, the adjustable angle range of the connecting plate 51 is ±5°.

[0042] In some embodiments, the scraper assembly 3 includes a mounting plate 31 and a flexible scraper 32, which are interconnected. The mounting plate 31 is rotatably mounted on the connecting plate 51. The mounting plate 31 facilitates the installation of the flexible scraper 32. With the flexible scraper 32, after the lifting drive 23 drives the flexible scraper 32 into contact with the mesh roller 100, the flexible scraper 32 elastically deforms, thereby ensuring effective contact between the flexible scraper 32 and the mesh roller 100 and increasing the contact area between the flexible scraper 32 and the mesh roller 100, thereby ensuring a more effective cleaning effect on the mesh roller 100. The flexible scraper 32 can be made of rubber or silicone.

[0043] In some embodiments, a second rotating shaft 33 extending along a third direction is fixedly provided on the mounting plate 31, and the second rotating shaft 33 is rotatably provided on the connecting plate 51. In this embodiment, the third direction is perpendicular to the second direction. In other embodiments, the second direction and the third direction may also have a certain angle. Through the above-mentioned arrangement, the connecting plate 51 can be rotated relative to the mounting plate 31, so that after the flexible scraper 32 abuts against the mesh roller 100, the angle can be adjusted within a certain angle range, so that the flexible scraper 32 can effectively fit with the mesh roller 100, ensuring the subsequent cleaning effect. In order to ensure the smooth rotation of the second rotating shaft 33, a bearing is installed at the mating point of the second rotating shaft 33 and the connecting plate 51. By providing a bearing, sliding friction can be converted into rolling friction, thereby ensuring the smooth rotation of the second rotating shaft 33.

[0044] In some embodiments, the floating connection assembly 5 further includes an elastic reset assembly, which includes a first elastic member 55 and a second elastic member 56, respectively disposed on either side of the second rotating shaft 33. One end of the first elastic member 55 is connected to one end of the mounting plate 31, and the other end of the first elastic member 55 is connected to the second rotating shaft 33. One end of the second elastic member 56 is connected to the other end of the mounting plate 31, and the other end of the second elastic member 56 is connected to the second rotating shaft 33. Specifically, the first elastic member 55 and the second elastic member 56 are symmetrically disposed, and the first elastic member 55 and the second elastic member 56 apply tension to the second rotating shaft 33 from opposite directions.

[0045] Specifically, the first elastic member 55 and the second elastic member 56 are both springs. A swing arm 331 is fixedly mounted on the second rotating shaft 33, and a first support 53 and a second support 54 are disposed at both ends of the mounting plate 31. The first elastic member 55 is connected to the first support 53 and the swing arm 331 at both ends, while the second elastic member 56 is connected to the second support 54 and the swing arm 331 at both ends. Both the first elastic member 55 and the second elastic member 56 are in a stretched state. The cooperation of the first elastic member 55 and the second elastic member 56 limits the floating deflection angle of the flexible scraper 32. Furthermore, after the flexible scraper 32 is separated from the screen roller 100, the first elastic member 55 and the second elastic member 56 can drive the flexible scraper 32 to reset.

[0046] Furthermore, the first support 53 is movable relative to the mounting plate 31. Specifically, the first support 53 can move relative to the mounting plate 31 in a direction away from or toward the second rotating shaft 33 to adjust the length of the first elastic member 55, thereby adjusting the tension of the first elastic member 55 on the second rotating shaft 33. In an optional embodiment, this is achieved through a threaded connection. The structure of the second support 54 is substantially identical to that of the first support 53 and will not be repeated here.

[0047] In some embodiments, the slurry removal assembly 4 includes an air pump and a nozzle 42 that are interconnected. The nozzle 42 is disposed toward the scraper assembly 3. Specifically, the nozzle 42 is fixed to the connecting base 21 via a mounting rod 41. The air pump sprays high-pressure gas through the nozzle 42 onto the flexible scraper 32 of the scraper assembly 3, thereby blowing the waste slurry away from the flexible scraper 32 and preventing the slurry from accumulating on the flexible scraper 32.

[0048] During daily production, when the roll-changing joint passes through the screen roller 100, the slurry scraper device is activated, the lifting drive member 23 is pressed down, and the flexible scraper 32 is pressed down. When the flexible scraper 32 contacts the screen roller 100, the connecting plate 51 swings slightly, and the mounting plate 31 swings under the action of the first elastic member 55 and the second elastic member 56 to ensure that the flexible scraper 32 is always in contact with the screen roller 100. The linear module 12 is activated, driving the flexible scraper 32 to move to the other end of the screen roller 100. The lifting drive member 23 is lifted, the rotary drive member 22 drives the flexible scraper 32 to rotate, and the nozzle 42 starts to ventilate to blow off the slurry spots on the flexible scraper 32. Then the blowing stops, the rotary drive member 22 is reset, and the linear module 12 drives the flexible scraper 32 back to the origin, waiting for the next scraping instruction.

[0049] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation methods here.
