Description

Technical Field

[0001] This utility model relates to the field of battery processing technology, and in particular to a rewinding device for PE composite separators in lead-acid batteries. Background Technology

[0002] Lead-acid batteries are a common type of battery, widely used in automobiles, UPS systems, solar energy storage, and other fields. In lead-acid batteries, the PE composite separator is a key component. It isolates the positive and negative electrodes, preventing short circuits caused by contact between the positive and negative electrodes, while allowing the flow of ions in the electrolyte to achieve the charging and discharging process of the battery.

[0003] Because some PE composite separators contain glass fibers, they are very difficult to pull apart during use. Forcibly pulling them apart will cause damage, deformation, and breakage of the PE composite separators, affecting their isolation performance and thus reducing the power of the lead-acid battery. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a rewinding device for PE composite separators in lead-acid batteries, which aims to improve the problem that in the prior art, PE composite separators contain glass fibers, and forced pulling will cause damage, deformation and destruction of the PE composite separator, affecting its isolation performance.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a rewinding device for PE composite separators in lead-acid batteries, comprising a worktable, a servo motor fixedly connected inside the worktable, the output end of the servo motor passing through the worktable and fixedly connected to a second winding ring, a support frame fixedly connected to one side of the outer wall of the worktable, an extension frame fixedly connected to the top of the support frame, a turntable rotatably connected to the top of the extension frame, a first winding ring fixedly connected to the front end of the turntable, composite separator material wound on the outer wall of the first winding ring, and a roller pressing mechanism fixedly connected to one side of the outer wall of the worktable.

[0006] As a further description of the above technical solution:

[0007] The roller pressing mechanism includes a fixed rod, which is rotatably connected to one side of the outer wall of the worktable. Both ends of the outer wall of the fixed rod are fixedly connected to connecting plates, and the same rotating rod is fixedly connected to one end of the inner side of the two connecting plates.

[0008] As a further description of the above technical solution:

[0009] The rolling mechanism also includes a circular roller, which is rotatably connected to the outer wall of the rotating rod.

[0010] As a further description of the above technical solution:

[0011] The workbench has evenly distributed heat dissipation holes on one side of its outer wall.

[0012] As a further description of the above technical solution:

[0013] A switch is fixedly connected to one side of the outer wall of the workbench, and the switch is electrically connected to the servo motor.

[0014] As a further description of the above technical solution:

[0015] A switch is fixedly connected to one side of the outer wall of the workbench, and the switch is electrically connected to the servo motor.

[0016] As a further description of the above technical solution:

[0017] A switch is fixedly connected to one side of the outer wall of the workbench, and the switch is electrically connected to the servo motor.

[0018] As a further description of the above technical solution:

[0019] The support frame has multiple counterweights fixedly connected at equal intervals inside.

[0020] As a further description of the above technical solution:

[0021] The first winding ring is connected to the second winding ring via a composite partition material.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the first winding ring and the second winding ring rotate in opposite directions to complete the stretching and reverse winding of the composite separator material, thereby realizing the rewinding of the entire roll of composite separator material. By pre-stretching, damage and deformation of the composite separator material during processing are avoided, ensuring the performance and quality of the processed lead-acid battery and reducing the risk of abnormalities in the lead-acid battery.

[0024] 2. In this utility model, the fixing rod hangs down under the gravity of the connecting plate and the rotating rod until the rotating rod contacts the surface of the rewinding composite partition material, so that there are no gaps inside the rewinding composite partition material during the winding process, which improves the winding effect of the composite partition material and further improves the rewinding quality of the composite partition material.

[0030] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1-3 An embodiment of this utility model provides a rewinding device for PE composite separators in lead-acid batteries, comprising a workbench 1, a servo motor 12 fixedly connected inside the workbench 1, the output end of the servo motor 12 passing through the workbench 1 and fixedly connected to a winding ring 9, a support frame 3 fixedly connected to one side of the outer wall of the workbench 1, an extension frame 4 fixedly connected to the top of the support frame 3, a turntable 6 rotatably connected to the top of the extension frame 4, a winding ring 7 fixedly connected to the front end of the turntable 6, composite separator material 8 being wound on the outer wall of the winding ring 7, and a roller pressing mechanism 11 fixedly connected to one side of the outer wall of the workbench 1.

[0032] The take-up ring 7 is connected to the take-up ring 9 via the composite partition material 8;

[0033] Specifically, the servo motor 12 rotates, driving the winding ring 2 9 to rotate. The winding ring 2 9, through the composite separator material 8, drives the winding ring 1 7 to rotate. The winding ring 1 7 rotates in the opposite direction to the winding ring 2 9, thereby completing the stretching and reverse winding of the composite separator material 8. This achieves the rewinding of the entire roll of composite separator material 8. By pre-stretching, damage and deformation of the composite separator material 8 during processing are avoided, ensuring the performance and quality of the processed lead-acid battery and reducing the risk of abnormalities in the lead-acid battery.

[0034] Reference Figure 2The roller pressing mechanism 11 includes a fixed rod 1101, which is rotatably connected to one side of the outer wall of the worktable 1. Both ends of the outer wall of the fixed rod 1101 are fixedly connected to a connecting plate 1102, and the same rotating rod 1103 is fixedly connected to one end of the inner side of the two connecting plates 1102.

[0035] The rolling mechanism 11 also includes a circular roller 1104, which is rotatably connected to the outer wall of the rotating rod 1103;

[0036] Specifically, during the rewinding process of the composite partition material 8, the fixed rod 1101 of the roller pressing mechanism 11 hangs down under the gravity of the connecting plate 1102 and the rotating rod 1103 until the rotating rod 1103 contacts the surface of the rewinded composite partition material 8, so that there are no gaps inside the rewinded composite partition material 8 during the winding process, which improves the winding effect of the composite partition material 8 and further improves the rewinding quality of the composite partition material 8. In addition, the circular roller 1104 transforms the sliding contact between the rotating rod 1103 and the outer wall of the composite partition material 8 into rolling contact, reducing the generation of friction and avoiding damage to the composite partition material 8 caused by friction.

[0037] Reference Figure 2 The outer wall of the workbench 1 has evenly distributed heat dissipation holes 10 on one side;

[0038] Specifically, the heat dissipation holes 10 accelerate the flow of heat generated by the servo motor 12 with the outside air, speeding up heat dissipation and preventing abnormal phenomena from occurring in the servo motor 12 under high heat.

[0039] Reference Figure 1 A switch 2 is fixedly connected to one side of the outer wall of the workbench 1, and the switch 2 is electrically connected to the servo motor 12.

[0040] Specifically, the servo motor 12 can be quickly turned on by switch 2, causing the winding ring 2 9 to rotate and drive the composite partition material 8 to be rolled back.

[0041] Reference Figure 1 Multiple counterweights 5 are fixedly connected at equal intervals inside the support frame 3;

[0042] Specifically, the counterweight 5 improves the support effect of the support frame 3 and prevents the support frame 3 from becoming unstable due to the tensile force generated when the composite partition material 8 is rolled back.

[0043] Working principle: The servo motor 12 rotates, driving the winding ring 2 9 to rotate. The winding ring 2 9 drives the winding ring 1 7 to rotate through the composite separator material 8. The winding ring 1 7 rotates in the opposite direction to the winding ring 2 9, thereby completing the stretching and reverse winding of the composite separator material 8, realizing the rewinding of the entire roll of composite separator material 8. Through pre-stretching, the internal adhesion of the composite separator material 8 is greatly reduced, avoiding damage and deformation of the composite separator material 8 during processing, ensuring the performance and quality of the processed lead-acid battery, and reducing the risk of abnormalities in the lead-acid battery. During the rewinding process of the composite separator material 8, the fixed rod 1101 of the roller pressing mechanism 11... Under the influence of gravity, the connecting plate 1102 and the rotating rod 1103 fall downwards until the rotating rod 1103 contacts the surface of the rewinding composite separator material 8. This ensures that there are no gaps inside the rewinding composite separator material 8 during the winding process, improving the winding effect of the composite separator material 8 and further enhancing the rewinding quality of the composite separator material 8. In addition, the roller 1104 transforms the sliding contact between the rotating rod 1103 and the outer wall of the composite separator material 8 into a rolling contact, reducing the friction between the surface of the composite separator material 8 and the rotating rod 1103, avoiding damage to the composite separator material 8 caused by friction, and further ensuring the quality of the lead-acid battery.
