Description

Technical Field

[0001] This invention belongs to the field of lithium-ion battery technology, specifically an assembled scraper structure. Background Technology

[0002] Electrode rolling is a critical control point in lithium battery manufacturing. The quality of rolling directly affects the performance of the battery cell. Therefore, when abnormalities such as sticking to the roller surface occur, the machine needs to be stopped for cleaning. Currently, in lithium battery manufacturing, a scraper is often added close to the roller surface to achieve real-time cleaning. However, after prolonged use, the scraper's blade may become damaged, leading to product quality issues, thus requiring replacement. Replacing the scraper requires a significant downtime, which reduces efficiency. Furthermore, even when the scraper is worn but still usable, gaps may remain between the scraper and the pressure roller, affecting its cleaning effect and resulting in poor performance.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] (1) During disassembly, the operator starts the first motor to run in the forward direction. The first motor drives the first sprocket to rotate. When the first sprocket rotates, it drives the second sprocket to rotate through the first chain. When the first sprocket and the second sprocket rotate, they both drive the first rotating rod to rotate along the inside of the first bushing. When the two first rotating rods rotate, they both drive the second bevel gear to rotate along the first shaft through the first bevel gear. When the second bevel gear rotates, it both drive the first helical gear to rotate along the second shaft through the first connecting rod. When the first helical gear rotates, it both drive the second rotating rod to rotate along the inside of the second bushing through the second helical gear.

[0015] When the second rotating rod rotates, it drives the pushing wheel to rotate along the third rotating shaft. After the pushing wheel rotates, it no longer pushes the contact plate. Under the force of the spring, it drives the moving rod to move inward. When the moving rod moves inward, it drives the locking block to move out of the slot and release the limit. Then the operator pulls the scraper body to pull the rubber ball out of the limit slot, thereby quickly removing the scraper body.

[0016] During installation, the operator inserts the connecting brackets of the two scraper bodies into the two connecting blocks respectively, and at the same time inserts the rubber ball into the limiting groove for temporary positioning. Then, the operator starts the first motor to run in reverse. When the first motor runs in reverse, it drives the pushing wheel to rotate and push the contact plate. When the contact plate is pushed, it drives the locking block to enter the slot through the moving rod, and at the same time, it compresses the spring, thereby quickly performing the limiting installation, making disassembly and assembly very convenient.

[0017] (2) When there is a wear gap between the scraper body and the pressure roller, the operator starts the second motor to drive the third sprocket to rotate. When the third sprocket rotates, it drives the fourth sprocket to rotate through the second chain. When the fourth sprocket and the third sprocket rotate, they both drive the fifth sprocket to rotate. When the two fifth sprockets rotate, they both drive the two sixth sprockets to rotate along the shaft seat through the third chain. When the sixth sprockets rotate, they both drive the third rotating rod to rotate along the inside of the third bushing.

[0018] When the third rotating rod rotates, it drives the threaded sleeve to move through the threaded rod. When the threaded sleeve moves, it drives the sliding sleeve to slide along the surface of the sliding rod, which increases the stability of the threaded sleeve when it moves. When both threaded sleeves move, they press the scraper body against the pressure roller, thus enabling effective cleaning.

[0019] (3) The scraper is very easy to replace, which greatly reduces the downtime of the equipment to replace the scraper, improves work efficiency, and can quickly press the scraper body against the pressure roller, which increases the cleaning effect. Attached Figure Description

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0033] Example 1, by Figures 1 to 9 The present invention includes a base 1, a device body 2 fixedly mounted on the top of the base 1, roller frames 3 fixedly mounted on the top and bottom of the device body 2, pressure rollers 4 rotatably mounted on the middle of the two roller frames 3, first L-shaped frames 5 symmetrically fixedly mounted on one side of the two roller frames 3, mounting blocks 6 fixedly mounted on the end of the first L-shaped frames 5 away from the roller frames 3, and a mounting box 8 fixedly mounted on the rear side of the device body 2. A quick-release assembly is provided inside the mounting box 8 and between the middle of the two mounting blocks 6 on the side close to each other. A scraper body 7 is rotatably mounted on the bottom of the quick-release assembly. Second L-shaped frames 10 are fixedly mounted on the bottom of the side close to each other of the mounting blocks 6. A quick-clamping assembly is provided between the side of the two second L-shaped frames 10 close to each other and the inside of the mounting box 8. The quick-clamping assembly contacts the two scraper bodies 7.

[0034] During disassembly, the operator starts the quick-release assembly to rotate forward. During forward rotation, the limit switch is quickly released, and the operator then pulls the scraper body 7 to quickly remove it. During installation, the operator inserts both scraper bodies 7 into the quick-release assembly for temporary positioning, then starts the assembly to rotate in reverse. Reverse rotation allows for quick limit installation, making disassembly and assembly very convenient. When there is a wear gap between the scraper body 7 and the pressure roller 4, the operator activates the quick-clamping assembly to clamp the scraper body 7 onto the pressure roller 4, effectively cleaning it. This makes scraper replacement very convenient, significantly reducing downtime and improving work efficiency. The quick clamping of the scraper body 7 onto the pressure roller 4 enhances the cleaning effect.

[0035] In Example 2, based on Example 1, the quick-assembly assembly includes a first motor 12, two connecting blocks 9, and a second sprocket 14. The first motor 12 is fixedly installed on the lower part of the rear inner wall of the mounting box 8. The two connecting blocks 9 are respectively fixed to the middle of the two mounting blocks 6 on their respective sides. Two connecting brackets 30 are symmetrically installed inside the two connecting blocks 9. The sides of the two connecting brackets 30 that are close to each other are rotatably connected to the opposite ends of the two scraper bodies 7. A first sprocket 13 is fixedly installed at the output end of the first motor 12. The second sprocket 14 is rotatably installed on the upper part of the rear inner wall of the mounting box 8. A first chain 15 is meshed between the second sprocket 14 and the first sprocket 13. One side of both the first sprocket 13 and the second sprocket 14 is fixedly installed. A first rotating rod 17 is fixedly installed, with one end of each first rotating rod 17 extending into the interior of the device body 2 and fixedly mounted with a first bevel gear 18. A first bushing 16 is rotatably mounted on the surface of each first rotating rod 17, and the outer surface of the first bushing 16 is fixedly mounted on the rear side of the device body 2. A second bevel gear 19 is meshed with one side of each first bevel gear 18. A first rotating shaft 20 is rotatably mounted on the side of each of the two second bevel gears 19 that is close to each other. The ends of the two first rotating shafts 20 that are close to each other are fixedly connected to a second L-shaped frame 10. A first connecting rod 21 is fixedly mounted on the side of each of the two second bevel gears 19 that is far from each other. A first helical gear 22 is fixedly mounted on the end of each of the two first connecting rods 21 that is far from each other. Each gear 22 has a second rotating shaft 23 rotatably mounted on its opposite side. Each of the two second rotating shafts 23 has a second connecting rod 24 fixedly mounted on its opposite side. One end of each of the two second connecting rods 24 is fixedly connected to the second L-shaped frame 10. Each of the first helical gears 22 has a second helical gear 25 meshing with it on one side. Each of the second helical gears 25 has a second rotating rod 26 fixedly mounted on one side. Each of the second rotating rods 26 has a second bushing 27 rotatably mounted on its surface. The outer surface of each second bushing 27 is fixedly connected to the connecting block 9. Each end of the second rotating rod 26 away from the second helical gear 25 extends into the interior of the connecting block 9 and has a pushing wheel 28 fixedly mounted thereon. Each pushing wheel 28 away from the second rotating rod 26 has a third rotating shaft 29 rotatably mounted on its opposite side. The end of the third rotating shaft 29 away from the pushing wheel 28 is fixedly connected to the inner wall of the connecting block 9; two limiting grooves 36 are opened on the inner wall of the two connecting blocks 9 on the side away from each other; two rubber balls 37 are fixedly installed on the side of the two connecting frames 30 away from each other; the rubber balls 37 are locked inside the limiting grooves 36; slots 33 are opened on both sides of the inner wall of the two connecting blocks 9; moving rods 31 are inserted into both sides of the two connecting frames 30; a locking block 32 is fixedly installed on the end of the moving rod 31 away from the pushing wheel 28; a contact plate 35 is fixedly installed on the end of the moving rod 31 close to the pushing wheel 28; springs 34 are provided on the surface of the moving rod 31; the two ends of the springs 34 are fixedly connected to the inner wall of the connecting frame 30 and the contact plate 35 respectively.

[0036] During disassembly, the operator starts the first motor 12 to rotate forward. The forward rotation of the first motor 12 drives the first sprocket 13 to rotate. When the first sprocket 13 rotates, it drives the second sprocket 14 to rotate via the first chain 15. Both the first sprocket 13 and the second sprocket 14 rotate, causing the first rotating rod 17 to rotate along the inside of the first bushing 16. When the two first rotating rods 17 rotate, they both drive the second bevel gear 19 to rotate along the first rotating shaft 20 via the first bevel gear 18. The rotation of the second bevel gear 19 then drives the first helical gear 22 to rotate along the second rotating shaft 23 via the first connecting rod 21. When the helical gear 22 rotates, it drives the second rotating rod 26 to rotate along the inside of the second bushing 27 through the second helical gear 25. When the second rotating rod 26 rotates, it drives the pushing wheel 28 to rotate along the third rotating shaft 29. After the pushing wheel 28 rotates, it no longer pushes the contact plate 35. Thus, under the elastic force of the spring 34, it drives the moving rod 31 to move inward. When the moving rod 31 moves inward, it drives the locking block 32 to move out of the inside of the locking groove 33 and release the limit. Then, the operator pulls the scraper body 7 and pulls the rubber ball 37 out of the inside of the limiting groove 36, thus quickly removing the scraper body 7.

[0037] During installation, the operator inserts the connecting brackets 30 of the two scraper bodies 7 into the two connecting blocks 9 respectively, and at the same time inserts the rubber ball 37 into the limiting groove 36 for temporary positioning. Then, the operator starts the first motor 12 to run in reverse. When the first motor 12 runs in reverse, it drives the pushing wheel 28 to rotate and push the contact plate 35. When the contact plate 35 is pushed, it drives the locking block 32 to lock into the slot 33 through the moving rod 31, and at the same time, it squeezes the spring 34, thereby quickly performing the limiting installation, making disassembly and assembly very convenient.

[0038] In Example 3, based on Example 1, the quick-clamping assembly includes a second motor 38, two mounting rods 11, and a fourth rotating shaft 40. The second motor 38 is fixedly mounted on the upper part of one side of the mounting box 8, and the fourth rotating shaft 40 is fixedly mounted on the lower part of one side of the mounting box 8. The two mounting rods 11 are respectively fixedly mounted on the sides of the two second L-shaped frames 10 that are close to each other. A third bushing 48 is fixedly mounted inside each of the two mounting rods 11. A third rotating rod 47 is rotatably mounted inside each of the third bushings 48. A sixth sprocket 44 is fixedly mounted at one end of each of the third rotating rods 47. A bearing seat 46 is rotatably mounted on one side of each of the sixth sprockets 44. The end of the bearing seat 46 away from the sixth sprocket 44 is fixedly connected to the mounting rod 11. A third... A fourth sprocket 41 is rotatably mounted on one end of a fourth shaft 40. A second chain 42 is meshed between the fourth sprocket 41 and the third sprocket 39. A fifth sprocket 43 is fixedly mounted on one side of both the third sprocket 39 and the fourth sprocket 41. A third chain 45 is meshed between the two fifth sprockets 43 and the two sixth sprockets 44. A threaded rod 49 is fixedly mounted on the end of each of the two third rotating rods 47 away from the sixth sprocket 44. A threaded sleeve 50 is threadedly connected to the surface of each threaded rod 49. A sliding sleeve 51 is fixedly mounted on the side of each of the two threaded sleeves 50 that is close to each other. A sliding rod 52 is inserted into the inside of each sliding sleeve 51. One end of each sliding rod 52 is fixedly connected to the mounting rod 11. One end of each of the two threaded sleeves 50 is tightly attached to the two scraper bodies 7.

[0039] The operator starts the second motor 38, which drives the third sprocket 39 to rotate. When the third sprocket 39 rotates, it drives the fourth sprocket 41 to rotate via the second chain 42. When the fourth sprocket 41 and the third sprocket 39 rotate, they both drive the fifth sprocket 43 to rotate. When the two fifth sprockets 43 rotate, they both drive the two sixth sprockets 44 to rotate along the shaft seat 46 via the third chain 45. When the sixth sprockets 44 rotate, they both drive the third rotating rod 47 to rotate along the inside of the third bushing 48. When the third rotating rod 47 rotates, it drives the threaded sleeve 50 to move via the threaded rod 49. When the threaded sleeve 50 moves, it drives the sliding sleeve 51 to slide along the surface of the sliding rod 52, which increases the stability of the threaded sleeve 50 when it moves. When the two threaded sleeves 50 move, they both press the scraper body 7 against the pressure roller 4, which can effectively clean the scraper.
