Abstract
Description
Technical Field
[0001] This utility model relates to the field of lithium battery separator production technology, specifically a rapid membrane insertion device. Background Technology
[0002] Lithium-ion battery separators are a key material in the new energy industry chain and are widely used in new energy vehicles, energy storage systems, and other fields. However, during the operation of lithium-ion battery separator production lines, separator breakage often occurs due to equipment failure or material problems. Therefore, it is necessary to perform a re-threading operation to pass the separator back through the various rollers, guide wheels, and processing areas of the production equipment in order to restore continuous production.
[0003] In existing technologies, the film threading operation is often performed manually. Operators need to manually start from the unwinding point and pass through each roller, sensor, coating slit, and other key locations along the path until reaching the rewinding end and fixing it. Due to the small internal space and complex path of the production equipment, manual operation is cumbersome and time-consuming, especially in high-speed wide-width production lines or when the equipment structure is compact. The long film threading time seriously affects the equipment utilization rate and production efficiency. In addition, the temperature in some areas inside the production equipment is high, and manual film threading also poses safety hazards.
[0004] Therefore, there is an urgent need for a rapid membrane threading device that can quickly thread the diaphragm through mechanical clamping, synchronous belt drive, and winding fixation to solve the problems of high difficulty and complex operation in the existing technology, improve the efficiency of membrane threading, and ensure the stability and safety of the diaphragm during the membrane threading process. Utility Model Content
[0005] The purpose of this invention is to provide a rapid membrane insertion device to solve the problems mentioned in the background art, so as to achieve rapid membrane insertion and improve membrane insertion efficiency.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A rapid film-feeding device includes a fixed base and multiple rollers rotatably connected inside the fixed base. Each roller has a timing pulley fitted at both ends. A timing belt meshes with the timing pulley on the same side. A clamping device for holding the film material is installed between two sets of timing belts. The clamping device includes two clamping plates that move in opposite directions or back to back. Bushings are installed at both ends of each clamping plate. An adjusting component for adjusting the distance between the two clamping plates is provided inside each bushing. A connecting shaft is fitted with the bushing with a clearance fit, and the connecting shaft is fixed to the timing belt.
[0008] As a further embodiment of this utility model: In order to enable the clamping plates to move towards or away from each other to clamp or release the film material, a cavity is provided inside the bushing, and the adjusting component includes a bidirectional lead screw rotatably disposed inside the bushing. One end of the bidirectional lead screw extends out of the bushing and is fixedly connected to a knob. A slider is threadedly connected to different threaded sections of the bidirectional lead screw. A guide portion is provided on the end face of the first end of the bushing, with the length direction consistent with the length direction of the bidirectional lead screw. One end of the slider passes through the guide portion and is fixedly connected to the corresponding clamping plate.
[0009] As a further embodiment of this utility model: In order to assist the adjustment component in driving the clamping plate to move and provide support, a driven component is installed in the bushing. The driven component and the adjustment component are installed in different bushings. The driven component includes a slide rod fixed in the bushing. Two sliders are slidably connected on the slide rod. A guide portion with the length direction consistent with the length direction of the slide rod is opened on the end face of the first end of the bushing. One end of the slider passes through the guide portion and is fixedly connected to the corresponding clamping plate.
[0010] As a further embodiment of this utility model: In order to keep the bushing fixed or rotate relative to the connecting shaft, a locking mechanism is installed inside the bushing. The locking mechanism includes a fixed block and a movable block embedded in the bushing. Both the movable block and the fixed block are provided with grooves for fitting the connecting shaft. The bushing is threadedly connected to a screw for adjusting the movable block to press or loosen the connecting shaft. One end of the screw extends out of the bushing and is fixedly connected to a knob.
[0011] As a further embodiment of this utility model: in order to provide support for the bidirectional lead screw and slide bar, a support plate is provided through the middle of both the bidirectional lead screw and slide bar, and the support plate is fixedly connected to the inner wall of the bushing.
[0012] As a further embodiment of this utility model: in order to prevent the clamping device from interfering with other parts during the transfer of the film material, a roller is sleeved on the roller shaft, and the radius of the roller is smaller than that of the synchronous pulley.
[0013] As a further aspect of this utility model: in order to reduce damage to the film material when winding it, the cross-section of the clamping plate is semi-circular.
[0014] As a further embodiment of this utility model: in order to reduce damage to the film material when clamping it, the two clamping plates are provided with clamping pads on the side walls on opposite sides.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] This utility model features a novel structure. The synchronous movement of the clamping device is achieved through the synchronous pulleys and belts at both ends of the roller shaft, ensuring uniform force on the film material during transport and preventing deviation or wrinkling. The adjusting and driven components of the clamping device work together to enable the clamping plates to move quickly and accurately towards or away from each other, significantly improving film threading efficiency and stability. The locking mechanism keeps the bushing and connecting shaft fixed or rotating relative to each other, facilitating the winding and fixing of the film material onto the clamping plates and preventing loosening, thus making film threading more stable. The support plate provides central support for the bidirectional lead screw and slide bar, reducing flexural deformation and extending component life. The shape of the clamping plates and the pads on them provide sufficient clamping force while avoiding damage to the diaphragm surface. Attached Figure Description

[0025] Please see Figure 1-4 In this embodiment of the present invention, a rapid film-threading device includes a fixed base 1 and multiple rollers 2 rotatably connected inside the fixed base 1. The rollers 2 are driven to rotate by a motor. Synchronous pulleys 3 are sleeved and fixed at both ends of the rollers 2. A ring-shaped synchronous belt 4 is meshed on the synchronous pulleys 3 on the same side. The rotation of the rollers 2 drives the synchronous pulleys 3 to rotate, and the rotation of the synchronous pulleys 3 drives the synchronous belt 4 to move. A clamping device 5 for clamping the film material is installed between the two sets of synchronous belts 4.
[0026] A roller 6 is sleeved and fixed on the outer periphery of the roller shaft 2. The roller 6 rotates together with the roller shaft 2 to transport the film material. The radius of the roller 6 is smaller than that of the synchronous belt pulley 3 to prevent the clamping device 5 from interfering with the roller 6 during the movement with the synchronous belt 4.
[0027] Two connecting shafts 51 at both ends of the clamping device 5 are welded to two corresponding sets of synchronous belts 4. The end face of the bushing 52 near the synchronous belt 4 is sleeved on the connecting shaft 51, and the bushing 52 and the connecting shaft 51 form a clearance fit to facilitate the rotation of the bushing 52 around the connecting shaft 51. The end of the bushing 52 away from the synchronous belt 4 is a cavity structure, and an adjustment component 53 for driving the two clamping plates 54 to move towards or away from each other is installed inside the bushing 52. The cross-section of the clamping plate 54 is semi-circular to reduce damage to the film material when the clamping device 5 winds it. Each of the two clamping plates 54 is provided with a clamping pad 541 on the side wall on the opposite side to increase the stability of clamping the film material and reduce damage to the film material during clamping. In this embodiment, the clamping pad is a rubber pad.
[0028] Please refer to Figure 2 The adjusting assembly 53 includes a bidirectional lead screw 531 rotatably disposed within the bushing 52. One end of the bidirectional lead screw 531 is embedded in the inner wall of the bushing 52, and the other end passes through the side wall of the bushing 52 and is welded with a knob 532 for adjusting the rotation of the bidirectional lead screw 531 within the bushing 52. The length direction of the bidirectional lead screw 531 is consistent with the radial direction of the bushing 52. Two threaded sections of the bidirectional lead screw 531 with opposite directions are respectively threaded with sliders 533. A first [missing information] is formed on the end face of the bushing 52 near the first end of the clamping plate 54. The guide part 534 has a length direction that is consistent with the length direction of the bidirectional lead screw 531. The end of the slider 533 away from the bidirectional lead screw 531 passes through the first guide part 534 and is welded to one end face of the corresponding clamping plate 54, so that the distance between the two clamping plates 54 can be adjusted by rotating the bidirectional lead screw 531. A support plate 57 passes through the middle of the bidirectional lead screw 531. The support plate 57 is perpendicular to the length direction of the bidirectional lead screw 531 and is welded to the inner wall of the bushing 52 along the radial direction of the bushing 52.
[0029] In this embodiment, the driven component 55 and the adjusting component 53 are respectively installed in two bushings 52. Please refer to [reference needed]. Figure 3 The driven component 55 includes a slide rod 551 welded to the inner wall of the bushing 52. The length direction of the slide rod 551 is consistent with the radial direction of the bushing 52. Two sliders 552 are slidably connected to the slide rod 551. A second guide portion 553 is provided on the end face of the bushing 52 near the first end of the clamping plate 54. The length direction of the second guide portion 553 is consistent with the length direction of the slide rod 551. The end of the slider 552 away from the slide rod 551 passes through the second guide portion 553 and is welded to the end face of the corresponding clamping plate 54, so that when the adjusting component 53 drives the clamping plate 54 to move towards or away from each other, the clamping plate 54 can move stably. A support plate 57 passes through the middle of the slide rod 551. The support plate 57 is perpendicular to the length direction of the slide rod 551 and welded to the inner wall of the bushing 52 along the radial direction of the bushing 52. In this embodiment, the first guide portion and the second guide portion are specifically configured as rectangular through slots.
[0030] A locking mechanism 56 can be installed in either the bushing 52 where the driven component 55 or the adjusting component 53 is installed. In this embodiment, the locking mechanism 56 and the driven component 55 are installed in the same bushing 52. Please refer to... Figure 4The locking mechanism 56 includes a fixed block 561 and a movable block 562 embedded in the bushing 52. Both the movable block 562 and the fixed block 561 have grooves for fitting the connecting shaft 51. The movable block 562 has a screw hole. The screw 563 is inserted into the outer wall of the bushing 52 along the radial direction and is threaded to the bushing 52. One end of the screw 563 inserted into the bushing 52 is also inserted into the movable block 562 and threaded to the screw hole of the movable block 562. A knob 564 is welded to one end of the screw 563 extending out of the bushing 52 to facilitate rotating the screw 563 to drive the movable block 562 to cooperate with the fixed block 561 to press the connecting shaft 51, so that the bushing 52 and the connecting shaft 51 are relatively fixed.
[0031] This utility model features a novel structure and stable operation. In use, when the film material breaks, it is first wound up so that the broken end protrudes from the inlet of the fixed seat 1. Then, the roller 2 drives the synchronous pulley 3 to reverse, thereby driving the synchronous belt 4 to move the clamping device 5 to the inlet of the fixed seat 1. The broken end of the film material is then inserted between the two clamping plates 54. Rotating the knob 532 drives the bidirectional lead screw 531 to rotate, driving the two sliders 533 to move the two clamping plates 54 towards each other until the two clamping pads 541 clamp and fix the broken end of the film material. Finally, rotating the bushing 52 rotates the two clamping plates 54. The film material is wound onto the outer wall of the clamping plate 54, improving the stability of the film material when it is pulled. After the film material is wound a few turns, the screw 563 is rotated by rotating the knob 2 564, causing the movable block 562 to move toward the fixed block 561. The movable block 562 and the fixed block 561 cooperate to clamp the connecting shaft 51, thereby locking the connecting shaft 51 and the bushing 52 to prevent the bushing 52 from rotating relative to the connecting shaft 51, which would cause the film material wound on the clamping plate 54 to loosen. Then, through the transmission of the roller 2, the synchronous pulley 3, and the synchronous belt 4, the clamping device 5 that holds and fixes the film material is moved to the outlet of the fixed seat 1 to complete the film threading operation.

Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
[0033] Therefore, the above description is only a preferred embodiment of this application and is not intended to limit the scope of this application; that is, all equivalent modifications made in accordance with the scope of the claims of this application shall be within the protection scope of the claims of this application.
