Technical Field

[0001] The utility model relates to the technical field of winding and pressing roller devices, in particular to a winding and pressing roller device for lithium battery production. Background Art

[0002] The winding and pressing roller device for lithium battery production is one of the important equipment in the lithium battery manufacturing process. Its main function is to wind and press the coated and dried pole pieces during the production process of lithium battery pole pieces. The winding and pressing roller device for lithium battery production is usually composed of a bracket support and a winding and pressing roller component.

[0003] As the equipment's operating time continues to increase, the rubber pressure roller is prone to wear. When the rubber pressure roller is worn to a certain extent, it needs to be replaced. Currently, most coil production and coating equipment on the market generally has the left and right ends of the winding pressure roller fixed, which makes subsequent maintenance and repair more difficult.

[0024] See also Figure 1-5 , the utility model provides a technical solution:

[0025] A winding and pressing roller device for lithium battery production includes a winding machine body 1 and a pressing roller assembly 2. A reel 101 is provided on one side of the winding machine body 1, a mounting seat 102 is provided at the bottom end of the winding machine body 1, and the pressing roller assembly 2 is provided on the outside of the mounting seat 102. Fixed disks 103 are provided on both sides of the winding machine body 1. The pressing roller assembly 2 includes two mounting rods 202 rotatably provided on the outside of the mounting seat 102, and a first driving cylinder 203 is rotatably provided on one side of the fixed disk 103.

[0026] Specifically, the mounting assembly 3 includes a mounting sleeve 301 mounted on one side of the two connecting blocks 208 close to each other, a limiting slide groove 304 is provided on the inner side wall of the mounting sleeve 301, and a matching block 302 is slidingly provided inside the mounting sleeve 301, a limiting slider 303 is provided on the outer side of the matching block 302, and a fixing plate 306 is fixedly connected to the side of the matching block 302 away from the mounting sleeve 301, and a limiting rod 307 is fixedly connected to the side of the fixing plate 306 away from the mounting sleeve 301, a second driving cylinder 305 is provided between the fixing plate 306 and the mounting sleeve 301, limiting grooves 308 are provided on both sides of the rubber pressure roller 201, the limiting slider 303 cooperates with the limiting slide groove 304, and the limiting slider 303 is slidably provided inside the limiting slide groove 304, the limiting rod 307 is configured as a square rod, and the limiting groove 308 is set to be a square groove, and the limit rod 307 and the limit groove 308 cooperate with each other. Therefore, when the rubber pressure roller 201 is severely worn and needs to be replaced after a period of use, the user can control the second driving cylinder 305 to retract, and then drive the fixed plates 306 to move away from each other, and drive the limit slider 303 to slide inside the limit slide groove 304, so that the matching block 302 slides inside the mounting sleeve 301 until the limit rod 307 is disengaged from the limit groove 308, thereby completing the disassembly of the rubber pressure roller 201. Afterwards, the second driving cylinder 305 can be controlled to extend, drive the limit rod 307 to be inserted into the limit groove 308, and drive the two fixed plates 306 to clamp on both sides of the rubber pressure roller 201 to complete the installation of the rubber pressure roller 201, so that the worn rubber pressure roller can be disassembled and replaced conveniently and quickly.

[0027] Furthermore, the first driving cylinder 203 is rotatably connected to the mounting rod 202 via a connecting shaft on the side away from the fixed disk 103. By controlling the extension of the first driving cylinder 203, the rubber pressure roller 201 is driven to press down, thereby driving the rubber pressure roller 201 to press down the reel 101 to complete the material pressing work.

[0028] Preferably, a mounting block 204 is provided on the side where the two mounting rods 202 are away from each other, a connecting rod 205 is provided inside the mounting block 204, an adjusting block 207 is provided on the outside of the connecting rod 205 for sliding, an adjusting spring 206 is provided on both sides of the adjusting block 207 and on the outside of the connecting rod 205, a connecting block 208 is connected and installed on the side where the two adjusting blocks 207 are close to each other, and a mounting assembly 3 for easy assembly and disassembly is provided on the side where the two connecting blocks 208 are close to each other. A rubber pressure roller 201 is installed on one side through the installation component 3, and a matching groove corresponding to the installation block 204 is provided on the side of the installation rod 202 away from the installation seat 102. During the winding process, the rubber pressure roller 201 presses the material. As the winding diameter of the reel 101 continues to increase, the reel 101 will have inconsistent sizes on the left and right. At this time, the compression amount of the spring 206 is adjusted to offset the inconsistent size of the reel 101, so that the rubber pressure roller 201 is always tightly pressed against the surface of the reel 101 to prevent slippage and ensure the quality of winding.

[0029] In summary, the utility model can conveniently and quickly disassemble and replace the worn rubber pressure roller, so as to facilitate the subsequent maintenance and repair of the rubber pressure roller.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
