Description

Technical Field

[0001] The utility model relates to the technical field of battery separator production, in particular to a cooling device for battery separator production. Background Technique

[0002] A battery separator refers to a separator material between the positive and negative electrodes of a battery, which is a very crucial part of the battery and has a direct impact on battery safety and cost. The production process of battery separators is divided into a wet process and a dry process. Among them, the asynchronous stretching production process of wet lithium battery separators generally includes the following processes: feeding and batching → extrusion and plasticization → sheet casting and cooling → longitudinal stretching → transverse stretching → extraction and drying → traction and shaping → winding and inspection;

[0003] At present, the cooling method of existing battery separators on the production line is to cool the surface of the battery separator through a spray cooler, and then wind up the cooled battery separator. However, such a cooling method can mostly only cool one side of the battery separator, resulting in uneven cooling of both sides of the battery separator. The battery separator cooled by this method is extremely prone to film breakage during the extraction process, and the actual use performance of the device is poor;

[0004] Moreover, most existing battery separators are cooled by a spray cooler during transportation at room temperature. Since the installation of the battery separator conveying device is relatively compact and the travel of the battery separator from the transverse stretching outlet to the extraction inlet is short, the overall cooling time of the battery separator film surface by the spray cooler is short, thereby reducing the cooling effect of the battery separator and affecting the comprehensive performance of the cooled battery separator.

[0038] Reference Figures 2-5 and Figure 11, the liquid cooling circulation mechanism includes a liquid cooling circulation component and a sealing component. The liquid cooling circulation component includes a plurality of conveying rollers 11 rotatably arranged in an S shape inside the installation groove 4. The conveying roller 11 includes a stainless steel cylinder 12 in contact with the surface of the battery separator, a first roller core 13 and a second roller core 14 for guiding the coolant.

On the second roll core 14, there are a third thread groove 25 and a first sealing groove 251 that match the threaded post 24 and the first sealing rubber ring 241. Inside the stainless steel cylinder 12, a first diversion channel 26 is formed. Inside the first roll core 13 and the second roll core 14, a second diversion channel 27 is formed. Inside the second diversion channel 27, there are a plurality of diversion holes 28 that communicate with the first diversion channel 26.

Inside the installation groove 4, there are a plurality of inclined diversion channels 29 that communicate with the second diversion channel 27. One of the inclined diversion channels 29 penetrates the side wall of the installation groove 4 and is connected to the return branch pipeline 10. Specifically, through the design of the liquid cooling circulation component, during the process of the conveying roll 11 conveying the battery separator, the coolant flowing through its interior can take away the heat on the surface of the battery separator in contact with the conveying roll 11. At the same time, through the S-shaped conveying roll 11 inside the cooling device, both sides of the battery separator can be cooled. Moreover, the S-shaped conveying roll 11 greatly extends the transportation stroke of the battery separator inside the cooling device, prolongs the residence time of the battery separator inside the cooling device, and effectively improves the cooling effect of the battery separator. Through the design of the fixing ring 15, the first thread tooth 16, the first thread groove 17, the annular clamping block 18, the guiding clamping block 19, the first installation hole 20, and the first compression spring 21, the detachable installation of the stainless steel cylinder 12 on the conveying device main body 1 is realized, which is convenient for the staff to repair and replace the stainless steel cylinder 12 subsequently and improves the practical performance of the device. Through the design of the first roll core 13, the second roll core 14, the second thread tooth 22, and the second thread groove 23, the detachable connection of the first roll core 13 and the second roll core 14 inside the stainless steel cylinder 12 is realized, so that when problems occur with the first roll core 13 and the second roll core 14, the staff can repair and replace the first roll core 13 and the second roll core 14 inside the stainless steel cylinder 12, further improving the practical performance of the device;

[0040] Through the design of the threaded column 24, the rubber sealing ring, the threaded groove three 25 and the sealing groove one 251, while realizing the detachable connection between the roller core one 13 and the roller core two 14, the design of the rubber sealing ring and the sealing groove one 251 is utilized to seal the connection between the roller core one 13 and the roller core two 14, thereby preventing the coolant flowing through the guide channel one 26 and the guide channel two 27 from flowing out through the connection between the roller core one 13 and the roller core two 14, thereby ensuring the normal operation of the liquid cooling circulation mechanism, and through the design of the guide channel one 26, the guide channel two 27 and the inclined guide channel 29 and the coordination of the input main pipeline 7 and the return branch pipeline 10, the circulation of the coolant inside the multiple conveying rollers 11 is realized, so as to timely take away the heat increased on the surface of the conveying roller 11 due to the conveying of the battery diaphragm, thereby achieving the purpose of cooling the surface of the battery diaphragm.

[0041] It should be noted that, in the present invention, the pitch between the thread teeth 22 and the thread column 24 is equal. Through this design, when the staff assembles the conveying roller 11, they can first screw the roller core 2 14 into the stainless steel tube 12, and then screw the roller core 13 into the thread groove 23 opened along the other side of the stainless steel tube 12. At this time, the thread column 24 at the end of the roller core 13 will be screwed into the thread groove 3 25 opened on the roller core 2 14. Therefore, under the premise of ensuring good sealing inside the conveying roller 11, the detachable installation between the roller core 13, the roller core 2 14 and the stainless steel tube 12 is realized, effectively ensuring the normal operation of the liquid cooling circulation mechanism.

[0042] Reference Figures 5-6 and Figures 8-9, the sealing assembly includes a sealing abutting block one 30 fixedly connected to one side of a first roller core 13 and a second roller core 14. On the side of the sealing abutting block one 30 opposite to the stainless steel cylinder 12, a second sealing rubber ring 31 is fixedly arranged. On the stainless steel cylinder 12, a second sealing groove 32 matching the second sealing rubber ring 31 is provided. On the side of the sealing abutting block one 30 opposite to the stainless steel cylinder 12, a sealing abutting block two 33 is abutted. On the side of the sealing abutting block one 30 opposite to the sealing abutting block two 33, a third sealing rubber ring 34 is fixedly arranged. On the sealing abutting block two 33, a third sealing groove 35 matching the third sealing rubber ring 34 is provided. Inside the sealing abutting block two 33, a plurality of second guiding and clamping blocks 36 are fixedly connected. Inside the conveying device main body 1, a second installation hole 37 matching the sealing abutting block two 33 and the second guiding and clamping blocks 36 is formed. On the side of the sealing abutting block two 33 away from the sealing abutting block one 30, a second compression spring 38 is provided. Both ends of the second compression spring 38 are fixedly connected to the sealing abutting block two 33 and the inner wall of the second installation hole 37. Specifically, through the design of the sealing assembly, while ensuring good sealing inside the conveying roller 11, it is convenient for staff to replace the damaged conveying roller 11, effectively improving the practical performance of the device. Through the design of the sealing abutting block one 30, the second sealing rubber ring 31, the second sealing groove 32, the sealing abutting block two 33, the third sealing rubber ring 34, the third sealing groove 35, the second guiding and clamping blocks 36, the second installation hole 37 and the second compression spring 38, the sealing between the first roller core 13 and the second roller core 14 on the conveying device main body 1 is realized, thereby preventing the coolant flowing through the first diversion channel 26 and the second diversion channel 27 from flowing out through the connection between the first roller core 13 and the second roller core 14 and the conveying device main body 1 due to the loose sealing between the first roller core 13 and the second roller core 14 and the conveying device main body 1, and dripping into the installation groove 4, causing unnecessary loss of the coolant, and improving the actual use effect of the device.

[0043] Refer to Figures 6-7 And Figure 10The sealing assembly also includes a plurality of guide blocks 39 fixedly arranged at one end of the roller core 2 14, a plurality of L-shaped plug-in grooves 40 matching the guide blocks 3 39 are arranged inside the oblique flow guide 29, and the ends of the L-shaped plug-in grooves 40 are connected with a card slot 41 matching the guide block 39, a compression spring 3 42 is fixedly arranged at the inner end of the card slot 41, and one end of the compression spring 3 42 is connected to a push block 43 for pushing the guide block 39, a plurality of mounting holes 3 44 connected to the card slot 41 are arranged inside the oblique flow guide 29, a compression spring 45 is fixedly connected to the side of the mounting hole 3 44 away from the push block 43, and one end of the compression spring 45 is fixedly connected to The push block 43 pushes out the L-shaped block 46 with position restriction, and the L-shaped block 46 is movably clamped in the mounting hole 3 44. The L-shaped block 46 is fixedly provided with an arc block 47 that matches the guide block 3 39. Specifically, through the design of the guide block 3 39, the L-shaped plug-in slot 40, the clamping slot 41, the compression spring 3 42, the push block 43, the mounting hole 3 44, the compression spring 45, the L-shaped block 46 and the arc block 47, the conveying roller 11 is stably installed on the conveying device body 1. When installing the conveying roller 11, the staff only needs to insert the end of the conveying roller 11 with the roller core 13 into the fixing ring 15, and press the fixing ring 15 to drive the annular block 18 and the sealing block 2 33 to move inward. , and compress the compression spring 1 21 and the compression spring 2 38, and then the other end of the conveying roller 11 is abutted against the outer end of another fixing ring 15 on the conveying device body 1, and then the staff rotates the fixing ring 15 located at one end of the roller core 13 to fix one end of the conveying roller 11, and then the staff rotates the conveying roller 11 so that the end with the roller core 2 14 is inserted into the conveying device body 1 along the L-shaped plug-in groove 40, and when the guide card block 3 39 is placed at the bottom of the L-shaped plug-in groove 40, the conveying roller 11 is rotated clockwise to make the guide card block 3 39 on the roller core 2 14 move along the L-shaped plug-in groove 40 toward the card slot 41, and the arc block 47 is squeezed, so that the arc block 47 pushes the L-shaped card block 46 to contract inward and gradually engage with the push block 43 The front end surface of the conveyor roller 11 is disengaged. At this time, the push block 43 drives the guide block 39 to move to the outer side of the card slot 41 under the action of the compression spring 3 42 until the guide block 39 fits into the card slot 41. Then the staff rotates the fixing ring 15 on one side of the roller core 14 to fix the other end of the conveyor roller 11, and the conveyor roller 11 is firmly installed on the conveyor device body 1. Through the design of multiple compression springs 3 42, the balance achieved by the compression springs 2 38 at both ends of the conveyor roller 11 is broken, so that the guide block 3 39 can be firmly stuck in the card slot 41, so that the conveyor roller 11 will not shake left and right due to the vibration of the conveyor device body 1 or the tension of the battery diaphragm, thereby improving the stability of the device operation. On the other hand;Through the design of the arc-shaped block 47, L-shaped clamping block 46 and the fourth compression spring 45, the position of the pushing block 43 is limited, so that when the pushing block 43 does not push the third guiding clamping block 39, it can be tightened inside the clamping groove 41. At this time, the outer end face of the pushing block 43 is flush with the inner side wall of the L-shaped insertion groove 40, so as to ensure the normal movement of the third guiding clamping block 39 in the L-shaped insertion groove 40 and the clamping groove 41, and maintain the normal use of the sealing assembly;

[0044] When it is necessary to disassemble the conveying roller 11, the staff only needs to loosen the fixing ring 15 on one side of the first roller core 13, so that the fixing ring 15 is separated from one end of the stainless steel cylinder 12, and then push the stainless steel cylinder 12 to one side of the first roller core 13, so that the third guiding clamping block 39 drives the pushing block 43 to move inward along the clamping groove 41 and squeeze the arc-shaped block 47. At this time, the L-shaped clamping block 46 is driven by the arc-shaped block 47 and placed into the third installation hole 44. When the bottom of the third guiding clamping block 39 is flush with the inner side wall of the L-shaped insertion groove 40, rotate the stainless steel cylinder 12 counterclockwise and push the stainless steel cylinder 12 along the L-shaped insertion groove 40 to one side of the first roller core 13, so that the third guiding clamping block 39 is withdrawn from the L-shaped insertion groove 40, thus completing the disassembly of one end of the stainless steel cylinder 12. During the counterclockwise rotation of the stainless steel cylinder 12, the arc-shaped block 47 and the L-shaped clamping block 46 pop out outward under the action of the fourth compression spring 45 and limit the position of the pushing block 43 for the normal use of the sealing assembly next time. Then the staff rotates the fixing ring 15 on the other side of the stainless steel cylinder 12 to separate it from the other side of the stainless steel cylinder 12, and the disassembly of the stainless steel cylinder 12 on the conveying device main body 1 can be completed. Then the staff screws out the first roller core 13 and the second roller core 14 from the stainless steel cylinder 12 in turn, and the disassembly of the conveying roller 11 can be completed.

The input end and the output end of the cooling flow channel 51 are respectively connected with the input branch pipeline 8 and the return branch pipeline 10. Specifically, through the design of the air-cooling mechanism, in cooperation with the liquid-cooling circulation mechanism, the battery separator transported inside the cooling device is further cooled, thereby improving the cooling effect of the battery separator inside the cooling device and enhancing the actual use effect of the device. When the air-cooling mechanism is working specifically, the coolant pumped out by the delivery pump 5 flows into the cooling flow channel 51 through the input main pipeline 7 and the input branch pipeline 8 to cool the mounting frame 48. Then, the coolant flows into the return main pipeline 9 through the return branch pipeline 10 opened on the other side of the mounting frame 48 and flows back to the coolant tank 2 through the return main pipeline 9, realizing the circulation of the coolant inside the air-cooling mechanism. During this process, the cooling fan 49 drives the external air to be filtered by the dust-proof net 50 and blown on the surface of the battery separator after the temperature of the mounting frame 48 is reduced, further cooling the battery separator. At the same time, the design of the dust-proof net 50 can also prevent the external dust from being blown onto the surface of the battery separator by the drive of the cooling fan 49, effectively ensuring the forming quality of the battery separator.

[0046] Refer to Figure 3 And Figure 11 , a plurality of stretching rollers 52 for stretching the battery separator are rotatably connected inside the mounting groove 4. Specifically, through the design of the stretching rollers 52, the battery separator during transportation is stretched to prevent the battery separator from being folded together due to the blowing of the cooling fan 49, resulting in a reduction in the contact area between the conveying roller 11 and the battery separator, further enhancing the actual use effect of the device.

[0047] It should be noted that in the present utility model, two sections of threads with opposite helix directions are provided on the stretching roller 52. Through this design, the part of the battery separator that is wrinkled due to the blowing of the cooling fan 49 is stretched to a certain extent, thereby preventing the battery separator from being stacked together and causing a reduction in the contact area between the conveying roller 11 and the battery separator, and improving the cooling effect of the battery separator.

[0048] The using process of a cooling device for battery separator production provided by the present utility model is as follows:

[0049] When cooling the battery diaphragm, the staff only needs to pass one end of the battery diaphragm around the receiving conveying roller 3 and the conveying roller 11 in turn and connect it to the external winding mechanism, and then start the conveying pump 5 to make the coolant in the coolant tank 2 flow into the liquid cooling circulation mechanism and the air cooling mechanism respectively through the conveying main pipeline and the conveying branch pipeline. The coolant flowing into the liquid cooling circulation mechanism flows into the guide channel 1 26 and the guide channel 2 27 opened in the multiple conveying rollers 11 through the inclined guide channel 29, and takes away the heat of the battery diaphragm in contact with the surface of the stainless steel cylinder 12 through the S-shaped design of the multiple conveying rollers 11, and then the coolant flows into the coolant tank 2 through the reflux main pipeline 9, realizing the coolant in the liquid cooling circulation mechanism. Circulation in the ring mechanism. During the operation of the liquid cooling circulation system, the coolant drawn by the delivery pump 5 flows into the cooling channel 51 through the input main pipe 7 and the input branch pipe 8 to cool the mounting frame 48. Then the coolant flows into the reflux main pipe 9 through the reflux branch pipe 10 opened on the other side of the mounting frame 48, and flows back to the coolant tank 2 through the reflux main pipe 9, thereby realizing the circulation of the coolant inside the air cooling mechanism. In this process, the staff starts the cooling fan 49 to drive the outside air to pass through the dustproof net 50 to filter and cool the mounting frame 48, and then blow it onto the surface of the battery diaphragm, thereby further cooling the battery diaphragm, thereby realizing double-sided cooling of the battery diaphragm in the mounting slot 4.
