Description

Technical Field

[0001] This utility model relates to the technical field of roller cleaning and maintenance structure, specifically to a roller for easy cleaning and maintenance of a battery core separation device. Background Technology

[0002] A battery core is formed by winding battery electrode sheets. The battery electrode sheets consist of a positive electrode sheet, a negative electrode sheet, and two layers of separators. The positive electrode sheet and the negative electrode sheet are separated by the two layers of separators, so that the positive electrode sheet is bonded between the two layers of separators and the negative electrode sheet is bonded to one layer. In the process of battery recycling, the battery electrode sheets need to be separated and recycled by separation equipment.

[0003] In the process of separating battery cores, battery core separation equipment requires rollers to transport and guide the positive electrode sheet, negative electrode sheet, and two layers of separator. The cleanliness design of the rollers in battery core separation equipment is an important factor in ensuring the efficient and stable operation of the equipment. However, in the existing technology, cleaning and maintenance are carried out manually after the roller transport and guidance operation is completed, which is inefficient and cannot be completed during the roller transport and guidance operation, thus affecting the quality of roller transport and guidance.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] In the description of this utility model, it should be understood that the terms indicating orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model; in the description of this utility model, "a plurality of" or "several" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0029] Please see Figure 1 As shown, this utility model is a roller shaft for easy cleaning and maintenance of a battery core separation device, including a cleaning roller 2 that is abutted against one side of a conveying roller shaft 1. The two ends of the cleaning roller 2 are detachably connected to sealing shaft covers 3. A drive mechanism is connected through the sealing shaft covers 3. A cleaning pipe 5 is arranged along the axial direction of the cleaning roller 2 and the sealing shaft covers 3 at both ends. A cleaning passage is formed between the cleaning pipe 5 and a plurality of cleaning holes 20 evenly distributed on the cleaning roller 2.

[0030] During use, the cleaning roller 2 can be driven by the drive mechanism to rotate and clean the surface of the conveyor roller shaft 1, ensuring that the surface of the conveyor roller shaft 1 is cleaned and maintained in all directions and thoroughly. However, during the rotation cleaning process, the heavily soiled areas on the surface of the conveyor roller shaft 1 cannot be cleaned by rotation. This application designs a cleaning passage between the cleaning pipe 5 and the multiple cleaning holes 20 evenly distributed on the cleaning roller 2, so that the surface of the conveyor roller shaft 1 can be wiped during the rotation of the cleaning roller 2, thereby cleaning the heavily soiled areas of the conveyor roller shaft 1. This allows the cleaning and maintenance to be completed during the conveying and guiding operation of the positive electrode sheet, negative electrode sheet, and two-layer separator without the need to stop the battery core separation equipment for cleaning.

[0031] In this specific embodiment, combined with Figure 2 As shown, multiple liquid supply holes 50 are evenly distributed on the cleaning pipe 5. When the cleaning roller 2 is driven to rotate by the drive mechanism, a cleaning passage is formed between the liquid supply holes 50 and the cleaning holes 20. The liquid supply holes 50 on the cleaning pipe 5 can deliver the cleaning liquid to the cleaning holes 20 and spray it out, so as to design and form a cleaning passage to wipe the surface of the conveying roller shaft 1.

[0032] In this specific embodiment, combined with Figure 2As shown, the cleaning roller 2 is provided with a hollow through-hole cavity 21. The hollow through-hole cavity 21 is separated by two partitions 51 to form a liquid storage cavity 7. The liquid storage cavity 7 is connected to the liquid supply port 50. When the liquid supply port 50 on the cleaning pipe 5 directly supplies cleaning fluid to the hollow through-hole cavity 21 on the cleaning roller 2, the cleaning fluid will follow the cleaning roller 2 and be centrifugally splashed, resulting in waste of cleaning fluid. It is also easy to splash onto the positive electrode plate, negative electrode plate, and two layers of diaphragm during the conveying and guiding operation. This application separates the liquid storage cavity 7 in the hollow through-hole cavity 21, and the cleaning pipe 5 can supply the cleaning fluid to the liquid storage cavity 7 through the liquid supply port 50 for temporary storage and use.

[0033] In this specific embodiment, combined with Figure 3 and Figure 4 As shown, the liquid storage chamber 7 is positioned directly opposite the conveyor roller shaft 1. When the cleaning port 20 on the cleaning roller 2 rotates to connect with the liquid storage chamber 7, a cleaning passage is formed between the liquid supply port 50, the liquid storage chamber 7, and the cleaning port 20. During the use of the liquid storage chamber 7 designed in this application, when the cleaning port 20 on the cleaning roller 2 rotates to connect with the liquid storage chamber 7, the cleaning passage formed will spray cleaning liquid from the cleaning port 20 to supply the surface of the conveyor roller shaft 1 for wiping and cleaning. When the cleaning port 20 on the cleaning roller 2 rotates to not connect with the liquid storage chamber 7, the cleaning roller 2 wipes the surface of the conveyor roller shaft 1 for wet stains. This application can achieve a combination of dry and wet sweeping to clean and maintain the surface of the conveyor roller shaft 1.

[0034] In this specific embodiment, combined with Figure 2 and Figure 5 As shown, the partition 51 is integrally set on the cleaning pipe 5, and the long side of the partition 51 abuts against the inner wall of the hollow through cavity 21, and the wide side abuts against the sealing shaft cover 3. The partition 51 designed in this application is placed in the hollow through cavity 21 of the cleaning roller 2 for use. The liquid storage cavity 7 is formed by the inner wall of the hollow through cavity 21, the two partitions 51 and the sealing shaft covers 3 at both ends to ensure the sealing and temporary storage function in the liquid storage cavity 7.

[0035] In this specific embodiment, combined with Figure 5 As shown, the sealing shaft cover 3 includes a sealing end cover body 30 detachably connected to the port face of the cleaning roller 2. The outer surface of the sealing end cover body 30 is integrally provided with a transmission shaft body 32. The inner surface of the sealing end cover body 30 is integrally provided with a sealing protrusion 31. The sealing protrusion 31 is inserted into the port of the cleaning roller 2 and seals with the hollow through hole cavity 21. The sealing shaft cover 3 designed in this application facilitates the disassembly and connection of the cleaning roller 2 through the sealing end cover body 30, so that the cleaning pipe 5 and its partition 51 can be installed in place, and then sealed by the sealing protrusion 31.

[0036] In this specific embodiment, combined with Figure 1 and Figure 5As shown, a driven pulley 6 is sleeved on the transmission shaft 32, and the driven pulley 6 is driven by the drive mechanism. The drive mechanism can be powered by a motor, and the output shaft of the motor can be driven by the drive pulley, the transmission belt and the driven pulley 6 to realize the rotation of the sweeping roller 2 to sweep the conveying roller shaft 1.

[0037] In this specific embodiment, combined with Figure 5 As shown, a transfer cover 4 is rotatably connected to the drive shaft 32, and a cleaning tube 5 is inserted into the transfer cover 4. The transfer cover 4 includes a limiting end cover 40 that abuts against the end face of the drive shaft 32. The limiting end cover 40 is provided with an integrally structured stabilizing protrusion 41, which is inserted into the drive shaft 32 and rotatably connected to it. In order to prevent the cleaning tube 5 from rotating with the cleaning roller 2 during use, the limiting end cover 40 can be installed on the frame of the battery core separation equipment, and the stabilizing protrusion 41 provides rotational support for the sealing cover 3, so that the cleaning tube 5 and the cleaning roller 2 can be rotated and separated.

[0038] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
