Technical Field
[0001] This utility model relates to the field of battery production technology, specifically a cooling device for battery separator production. Background Technology
[0002] A battery separator is a membrane material placed between the positive and negative electrodes of a battery. It is a very critical component of a battery and has a direct impact on battery safety and cost. Its main function is to isolate the positive and negative electrodes and prevent electrons from passing freely through the battery, while allowing ions in the electrolyte to pass freely between the positive and negative electrodes. The ion conductivity of the battery separator is directly related to the overall performance of the battery.
[0003] In battery separator production, molten polymer materials need to be rapidly cooled after extrusion molding to form a microporous structure. Current cooling devices can cool the surface of the battery separator using a cooler, and then the cooled battery separator is rolled up. However, this cooling method cannot cool the back of the battery separator, resulting in poor cooling effect. Furthermore, when cooling with a cooler, the cooling port is fixed, and there is a continuous direct blowing from the cooling port during cooling, which may cause deformation of the battery separator and affect the yield of the product. To address the above problems, the inventors propose a cooling device for battery separator production to solve the above problems. Utility Model Content
[0004] To address the current issues of inability to perform double-sided cooling and the potential deformation of battery separators due to continuous direct airflow from the cooling vents, this invention aims to provide a cooling device for battery separator production.
[0005] To solve the above technical problems, the present invention adopts the following technical solution: a cooling device for battery separator production, comprising a base, a cooling platform fixedly connected to the top surface of the base, a housing provided above the base, a fixed seat fixedly connected to the inner wall of the housing, a motor provided below the fixed seat, an extension shaft fixedly connected to the output shaft end of the motor, a half-face gear fixedly connected to the shaft end of the extension shaft, a first ring body provided on both sides of the motor, teeth fixedly connected to the inner wall of the first ring body, the half-face gear corresponding to and meshing with the teeth, an actuating frame fixedly connected to the side wall of the first ring body, a horizontal shaft inserted and fixedly connected to the upper part of the side wall of the fixed seat, a ring sleeve rotatably sleeved on the side wall of the horizontal shaft, a second ring body fixedly connected to the bottom surface of the ring sleeve, the rod end of the actuating frame located inside the ring opening of the second ring body, and a cooling air pipe provided on the bottom surface of the second ring body.
[0006] Preferably, a support plate is fixedly connected to the outer wall of the housing, and the bottom surface of the support plate is fixedly connected to the top surface of the base. A connecting seat is provided on the side wall of the motor, and the top surface of the connecting seat is fixedly connected to the bottom surface of the fixed seat. The support plate is used to support and fix the housing. The motor is installed through the connecting seat. When the motor is started, the extended shaft can drive the half-face gear to rotate under the action of the motor output shaft. A slide rail is fixedly connected to the outer wall of the first ring, and a cavity plate is slidably connected to the side wall of the slide rail. The side wall of the cavity plate is fixedly connected to the side wall of the fixed seat. When the half-face gear rotates, the first ring can move smoothly through the meshing of the half-face gear and the cooperation of the slide rail and the cavity plate. This allows the actuating frame to move within the ring opening of the second ring to apply a thrust to the second ring. This causes the second ring to swing around the horizontal axis through the ring sleeve. This allows the cooling pipe to swing through the protruding plate to increase the cooling area and avoid deformation of the battery separator body caused by continuous direct blowing.
[0007] Preferably, a protruding plate is fixedly connected to the bottom end of the second ring body. The side of the protruding plate away from the second ring body is fixedly connected to the outer wall of the cooling pipe. A rectangular groove is provided on the bottom surface of the housing. The protruding plate is located in the rectangular groove and cooperates with the rectangular groove. The protruding plate can move back and forth in the rectangular groove. When the second ring body swings around the horizontal axis, the cooling pipe can swing through the protruding plate, thereby cooling the cooling area of the jet nozzle to avoid the continuous direct blowing of the jet nozzle, which could cause deformation of the battery separator body. A cooling supply connector is fixedly connected to the end face of the cooling pipe. The pipe includes a jet nozzle facing the cooling platform. A cooling roller is embedded in the top surface of the cooling platform. A cold air supply connector is used to connect to the output end of an external air conditioner. The cooling roller and air conditioner are existing mature products and are directly selected here. A battery separator body is set on the cooling platform. When the battery separator body moves on the cooling platform, the back of the battery separator body can be cooled by the cooling roller, and the surface of the battery separator body can be cooled by the jet nozzle, thereby achieving double-sided cooling of the battery separator body to improve the cooling effect.
[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: by cooperating with the cooling roller and the cooling air pipe, double-sided cooling of the battery separator body can be achieved to improve the cooling effect. During cooling, the second ring body can swing around the horizontal axis under the action of the actuating frame, and the cooling air pipe can be swung by the convex plate to increase the cooling area and avoid the battery separator body from being deformed by the continuous direct blowing of the jet nozzle, thus ensuring the product yield.

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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] Example: Figure 1-4As shown, this utility model provides a cooling device for battery separator production, including a base 1, a cooling platform 21 fixedly connected to the top surface of the base 1, a housing 2 above the base 1, a fixing seat 5 fixedly connected to the inner wall of the housing 2, a motor 6 below the fixing seat 5, an extension shaft 8 fixedly connected to the output shaft end of the motor 6, a half-face gear 9 fixedly connected to the shaft end of the extension shaft 8, a first ring body 10 on both sides of the motor 6, teeth 11 fixedly connected to the inner wall of the first ring body 10, the half-face gear 9 corresponding to and meshing with the teeth 11, an actuating frame 14 fixedly connected to the side wall of the first ring body 10, a horizontal shaft 15 inserted and fixedly connected to the upper part of the side wall of the fixing seat 5, a ring sleeve 16 rotatably sleeved on the side wall of the horizontal shaft 15, a second ring body 17 fixedly connected to the bottom surface of the ring sleeve 16, the rod end of the actuating frame 14 located inside the ring opening of the second ring body 17, and a cooling air pipe 19 provided on the bottom surface of the second ring body 17.
[0017] A support plate 3 is fixedly connected to the outer wall of the housing 2. The bottom surface of the support plate 3 is fixedly connected to the top surface of the base 1. A connecting seat 7 is provided on the side wall of the motor 6. The top surface of the connecting seat 7 is fixedly connected to the bottom surface of the fixed seat 5.
[0018] By adopting the above technical solution, the support plate 3 is used to support and fix the housing 2, and the motor 6 is installed through the connecting seat 7. When the motor 6 is started, the extended shaft 8 can drive the half-face gear 9 to rotate under the action of the output shaft of the motor 6.
[0019] A slide rail 12 is fixedly connected to the outer side wall of the first ring body 10, and a cavity plate 13 is slidably connected to the side wall of the slide rail 12. The side wall of the cavity plate 13 is fixedly connected to the side wall of the fixed seat 5.
[0020] By adopting the above technical solution, when the half-face gear 9 rotates, the first ring body 10 can move smoothly through the meshing of the half-face gear 9 and the teeth 11, and the cooperation of the slide rail 12 and the cavity plate 13. This allows the actuating frame 14 to move within the ring opening of the second ring body 17 to apply a thrust to the second ring body 17. The ring sleeve 16 causes the second ring body 17 to swing around the horizontal axis 15, and the convex plate 18 causes the cooling pipe 19 to swing, thereby increasing the cooling area and avoiding deformation of the battery separator body 23 caused by continuous direct blowing.
[0021] The bottom end of the second ring body 17 is fixedly connected to a protruding plate 18. The side of the protruding plate 18 away from the second ring body 17 is fixedly connected to the outer wall of the air duct 19. The bottom surface of the housing 2 is provided with a rectangular groove 4. The protruding plate 18 is located in the rectangular groove 4 and the protruding plate 18 cooperates with the rectangular groove 4.
[0022] By adopting the above technical solution, the convex plate 18 can move back and forth in the rectangular groove 4. When the second ring body 17 swings around the horizontal axis 15, the convex plate 18 can make the cooling pipe 19 swing, thereby cooling the cooling area of the jet head 20, so as to avoid the continuous direct blowing of the jet head 20 and causing the battery separator body 23 to deform.
[0023] A cold air supply connector is fixedly connected to the end face of the cold air pipe 19. The cold air pipe 19 includes a jet nozzle 20, which faces the cooling platform 21. A cooling roller 22 is embedded in the top surface of the cooling platform 21.
[0024] By adopting the above technical solution, the air supply connector is used to connect to the output end of the external air conditioner. The cooling roller 22 and the air conditioner are existing mature products, and are directly selected here. The battery separator body 23 is set on the cooling platform 21. When the battery separator body 23 moves on the cooling platform 21, the back of the battery separator body 23 can be cooled by the cooling roller 22, and the surface of the battery separator body 23 can be cooled by the jet nozzle 20, thereby achieving double-sided cooling of the battery separator body 23 to improve the cooling effect.
[0025] Working principle: When the battery separator body 23 moves on the cooling platform 21, the back side of the battery separator body 23 can be cooled by the cooling roller 22. At the same time, the cold air supply connector is connected to the output end of the external air conditioner, and the cold air enters into the cold air pipe 19 and is then sprayed out through the jet nozzle 20 to cool the surface of the battery separator body 23. Thus, double-sided cooling of the battery separator body 23 can be achieved to improve the cooling effect.
[0026] Simultaneously, the motor 6 is started, and the extended shaft 8 can drive the half-face gear 9 to rotate under the action of the output shaft of the motor 6. Through the meshing of the half-face gear 9 and the teeth 11, and the cooperation of the slide rail 12 and the cavity plate 13, the first ring body 10 can move smoothly, and the toggle bracket 14 can move within the ring opening of the second ring body 17 to apply a thrust to the second ring body 17. Through the ring sleeve 16, the second ring body 17 can swing around the horizontal axis 15, and the cooling pipe 19 can swing through the convex plate 18 to increase the cooling area and prevent the battery separator body 23 from being deformed due to the continuous direct blowing of the jet nozzle 20.
