Technical Field

[0001] This utility model relates to the field of flattening device technology, specifically a thin film flattening device for a lithium battery separator production line. Background Technology

[0002] In the production process of lithium battery separators, film flattening is a crucial step. The function of the film flattening device is to flatten the film that has become wrinkled during production, thereby ensuring the quality of the lithium battery separator and production efficiency. As the core component of the film flattening device, the ease of installation and maintenance, as well as the accuracy of the installation inspection, directly affect the operation of the entire production line.

[0003] Existing film flattening devices typically use bolts to fix the flattening rollers during installation, requiring tools to tighten each bolt individually. This installation process is cumbersome and consumes a lot of installation time and labor costs. Moreover, when disassembling the flattening rollers for maintenance or replacement, tools are also needed to loosen each bolt individually, making the operation complicated. Therefore, a film flattening device for lithium battery separator production lines is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a thin film flattening device for a lithium battery separator production line to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a film flattening device for a lithium battery separator production line, comprising an operating table located on one side of the lithium battery separator production line, two connecting plates on the top of the operating table, and flattening rollers rotatably connected between the two connecting plates, wherein the surface of the flattening rollers contacts the film and flattens it.

[0006] An adjustment component is provided on the lower side of the operating table, and a limiting component for disassembling and assembling the flattening roller is provided on one side of the adjustment component;

[0007] The limiting component includes two support frames and a prompting mechanism. The support frame has a first sliding groove inside, and a sliding plate is slidably connected to the inside of the first sliding groove. A pull rod and a locking block are fixed on both sides of the sliding plate, respectively.

[0008] A first spring connects the first slide and the slide plate;

[0009] The prompting mechanism includes a slider, and a sliding rod is fixed to the top of the slider.

[0010] Preferably, the top of the support frame is connected to a cover plate by screws, and a protrusion is fixed to the side of the connecting plate away from the flattening roller.

[0011] Preferably, the protrusion has a locking groove on one side. When the locking block is inserted into the locking groove, the flattening roller is in a fixed state. When the locking block leaves the locking groove, the flattening roller is in a disassembled state.

[0012] Preferably, the adjustment assembly includes two limiting plates, each limiting plate being rotatably connected to a rotating shaft. The rotating shaft has two threaded sections on its outer side, with the threads of the two threaded sections having opposite directions.

[0013] Preferably, the bottom of the operating table is fixed with a fixing frame on both sides, and a guide rod inserted into one side of the limiting plate is fixed between the fixing frames.

[0014] Preferably, as described above, one end of the rotating shaft is fixed with a handwheel, one side of the handwheel is threaded with a bolt, one end of the bolt abuts against one side of the fixing frame, and the outer side of the rotating shaft is rotatably connected to one side of the fixing frame.

[0015] Preferably, the threaded section is threaded to a vertical plate, a limiting groove is formed on one side of the top of the vertical plate, the outer side of the protrusion is adapted to the inner side of the limiting groove, the limiting plate is fixed to the bottom of the operating table, and the vertical plate is slidably connected to the outer side of the guide rod through a linear bearing.

[0016] Preferably, the vertical plate has a second sliding groove on its inner side, a second spring is connected between the second sliding groove and the slider, and the support frame is fixed to one side of the vertical plate.

[0017] Compared with the prior art, the present invention, by adopting the above technical solution, has the following technical effects:

[0018] When installing the flattening roller, simply insert the protrusion into the corresponding position. With the help of the elastic force of the first spring, the slide plate automatically slides in the first groove, pushing the locking block into the inner side of the locking groove. This quickly fixes the flattening roller, allowing it to enter normal flattening working state rapidly, saving installation time and labor costs. When it is necessary to disassemble the flattening roller, simply pull the lever to compress the first spring, causing the locking block to leave the inner side of the locking groove, making the flattening roller detachable. The operation is simple and easy to understand, facilitating maintenance and replacement of the flattening roller.

[0019] The sliding rod is pressed down by the protrusion, which pushes the slider down and compresses the second spring. When the bottom of the slider contacts the inner wall of the second groove and the bottom of the protrusion contacts the bottom of the inner wall of the limiting groove, it clearly indicates that the flattening roller is installed in place. This eliminates the need for complex testing tools or cumbersome testing procedures, greatly simplifying the inspection process and improving installation efficiency.

[0020] By turning the handwheel to drive the shaft to rotate, and utilizing the limiting effect of the two threaded sections with opposite directions and the guide rod, the two vertical plates can be easily moved towards or away from each other, thereby quickly adjusting the distance between them. The operation is simple and easy to understand, requiring no complicated tools or professional skills. Operators can quickly complete the distance adjustment work, greatly improving work efficiency.

Example

[0030] Please see Figure 1-5 This utility model provides a technical solution: a film flattening device for a lithium battery separator production line, including an operating table 1 located on one side of the lithium battery separator production line. The top of the operating table 1 is provided with two connecting plates 6, and flattening rollers 2 are rotatably connected between the two connecting plates 6. The flattening rollers 2 are driven to rotate by the movement of the film, and the friction between the roller surface and the film is used to flatten the film and eliminate wrinkles. The surface of the flattening rollers 2 contacts the film and flattens it. The rotation direction of the flattening rollers 2 is consistent with the movement direction of the film, and the wrinkles are smoothed out by friction. An adjustment component 3 is provided on the lower side of the operating table 1, and a limiting component 5 for disassembling and assembling the flattening rollers 2 is provided on one side of the adjustment component 3.

[0031] The limiting component 5 includes two support frames 51 and a prompting mechanism. The support frame 51 has a first slide groove 52 inside. A slide plate 55 is slidably connected to the inside of the first slide groove 52. A pull rod 53 and a locking block 510 are fixed on both sides of the slide plate 55 respectively. Under the action of the first spring 54, the slide plate 55 pushes the locking block 510 into the locking groove 511 of the protrusion 512. When the locking block 510 is fully embedded in the locking groove 511, the flattening roller 2 is axially limited to prevent it from moving axially along the rotating shaft 37 and to ensure flattening stability. The first spring 54 is connected between the first slide groove 52 and the slide plate 55.

[0032] The prompting mechanism includes a slider 58, with a sliding rod 56 fixed to the top of the slider 58. When the flattening roller 2 is located inside the limiting groove 38, the protrusion 512 presses down on the sliding rod 56, and the sliding rod 56 pushes the slider 58 downward. When the bottom of the slider 58 contacts the inner wall of the second sliding groove 59, the bottom of the protrusion 512 contacts the bottom of the inner wall of the limiting groove 38. The operator can tell that the protrusion 512 is installed in place by visually observing that the slider 58 contacts the bottom of the inner wall of the second sliding groove 59. The top of the support frame 51 is connected to the cover plate 4 by screws. After removing the screws and the cover plate 4, the first spring 54 can be replaced. The protrusion 512 is fixed on the side of the connecting plate 6 away from the flattening roller 2.

[0033] A locking groove 511 is provided on one side of the protrusion 512. When the locking block 510 is inserted into the inner side of the locking groove 511, the flattening roller 2 is in a fixed state. When the locking block 510 leaves the inner side of the locking groove 511, the flattening roller 2 is in a disassembled state. When disassembling the flattening roller 2, the pull rod 53 is pulled to compress the first spring 54 of the slide plate 55, and the locking block 510 is disengaged from the locking groove 511. At this time, the protrusion 512 can be pulled out from the limiting groove 38 of the vertical plate 32. After replacing the flattening roller 2, the pull rod 53 is released, and the first spring 54 is reset to push the locking block 510 to lock automatically, realizing quick installation.

[0034] The adjustment assembly 3 includes two limiting plates 33, each rotatably connected to a rotating shaft 37. Two threaded sections 35 are provided on the outer side of the rotating shaft 37, with the threads of the two sections 35 in opposite directions. Fixing frames 34 are fixed on both sides of the bottom of the operating table 1. A guide rod 36, inserted into one side of the limiting plate 33, is fixed between the fixing frames 34. When the handwheel is turned to rotate the rotating shaft 37, a screw guard is fitted onto the outer side of both the rotating shaft 37 and the guide rod 36. The two ends of the screw guard are respectively connected between the vertical plate 32, the limiting plate 33, and the fixing frame 34. The screw guard is periodically removed to apply lubricant to the threaded sections 35 for maintenance. The two vertical plates 32 move towards or away from each other along the guide rod 36 under the threaded drive, thereby adjusting the distance between the two flattening rollers 2 to accommodate films of different widths.

[0035] A handwheel is fixed to one end of the rotating shaft 37, and a bolt is threaded to one side of the handwheel. One end of the bolt abuts against one side of the fixing frame 34. The outer side of the rotating shaft 37 is rotatably connected to one side of the fixing frame 34. After removing the flattening roller 2, the handwheel is turned to drive the rotating shaft 37 to rotate. The distance between the two vertical plates 32 is adjusted so that different connecting plates 6 and flattening rollers 2 can be replaced according to the different widths and thicknesses of the film. The flattening rollers 2 have different lengths and different distances between adjacent flattening rollers 2. The appropriate flattening roller 2 is selected according to the type of film.

[0036] A vertical plate 32 is threadedly connected to the outer side of the threaded section 35. A limiting groove 38 is opened on one side of the top of the vertical plate 32. The outer side of the protrusion 512 is adapted to the inner side of the limiting groove 38. The limiting plate 33 is fixed to the bottom of the operating table 1. The vertical plate 32 is slidably connected to the outer side of the guide rod 36 through a linear bearing. A second sliding groove 59 is opened on the inner side of the vertical plate 32. A second spring 57 is connected between the second sliding groove 59 and the slider 58. When the protrusion 512 is inserted into the limiting groove 38, its bottom presses down the sliding rod 56, pushing the slider 58 to move down along the second sliding groove 59. When the bottom of the slider 58 contacts the inner wall of the second sliding groove 59, it indicates that the protrusion 512 has been installed in place. The operator can confirm the position of the slider 58 by visual inspection, thus avoiding equipment failure caused by improper installation.

[0037] A baffle (not shown in the figure) for replacing the second spring 57 is connected to one side of the vertical plate 32. The second spring 57 can be replaced by opening the baffle. The support frame 51 is fixed to one side of the vertical plate 32. The distance between the two vertical plates 32 can be adjusted by adjusting the component 3. Different lengths or diameters of flattening rollers 2 can be replaced to adapt to films of different thicknesses.

[0038] Working principle: The top of the operating table 1 is equipped with two connecting plates 6, and the two connecting plates 6 are rotatably connected with upper and lower distributed flattening rollers 2. During the operation of the lithium battery separator production line, when the film passes through the flattening rollers 2, the surface of the flattening rollers 2 contacts the film. Through its rotation and the friction between it and the film, the film is flattened during the process of moving, ensuring the flatness of the film to meet the requirements of subsequent production processes.

[0039] When installing the flattening roller 2, insert the protrusion 512 into the corresponding position. Under the elastic force of the first spring 54, the slide plate 55 slides within the first groove 52, pushing the locking block 510 into the inner side of the locking groove 511. At this time, the flattening roller 2 is in a fixed state and can perform flattening work normally. When it is necessary to disassemble the flattening roller 2, pull the pull rod 53, causing the slide plate 55 to compress the first spring 54, so that the locking block 510 leaves the inner side of the locking groove 511, and the flattening roller 2 is in a detachable state.

[0040] When the flattening roller 2 is installed, the protrusion 512 presses down on the slide bar 56, and the slide bar 56 pushes the slider 58 downward and compresses the second spring 57. When the bottom of the slider 58 contacts the inner wall of the second slide groove 59, the bottom of the protrusion 512 contacts the bottom of the inner wall of the limiting groove 38. At this time, the operator can know that the protrusion 512 is installed in place by visually observing that the slider 58 is in contact with the bottom of the inner wall of the second slide groove 59, which means that the flattening roller 2 is installed in place.

[0041] When it is necessary to adjust the distance between the two vertical plates 32, turn the handwheel to drive the rotating shaft 37 to rotate. Since the threads of the two threaded sections 35 are opposite, under the limiting action of the guide rod 36, the two vertical plates 32 will move towards or away from each other along the guide rod 36, thereby achieving the purpose of adjusting the distance between the two vertical plates 32. One end of the rotating shaft 37 is fixed with a handwheel, and a bolt is threadedly connected to one side of the handwheel. One end of the bolt abuts against one side of the fixing frame 34. After the distance is adjusted, tighten the bolt so that one end of the bolt tightly abuts against one side of the fixing frame 34, thereby fixing the position of the rotating shaft 37, preventing it from rotating, and ensuring the stability after the distance is adjusted. Replace with flattening rollers 2 of different lengths and different adjacent distances and corresponding connecting plates 6 to meet the flattening requirements of different types of films.

[0042] In summary, when installing the flattening roller 2, simply insert the protrusion 512 into the corresponding position. With the help of the elastic force of the first spring 54, the slide plate 55 automatically slides in the first slide groove 52, pushing the locking block 510 into the inner side of the locking groove 511. This quickly completes the fixing of the flattening roller 2, allowing it to quickly enter the normal flattening working state, saving installation time and labor costs. When it is necessary to disassemble the flattening roller 2, simply pull the pull rod 53 to drive the slide plate 55 to compress the first spring 54, which will cause the locking block 510 to leave the inner side of the locking groove 511, making the flattening roller 2 detachable. The operation is simple and easy to understand, facilitating maintenance, replacement, and other operations of the flattening roller 2.

[0043] The sliding rod 56 is pressed down by the protrusion 512, which pushes the slider 58 downward and compresses the second spring 57. When the bottom of the slider 58 contacts the inner wall of the second groove 59 and the bottom of the protrusion 512 contacts the bottom of the inner wall of the limiting groove 38, it clearly indicates that the flattening roller 2 is installed in place. This eliminates the need for complex testing tools or cumbersome testing procedures, greatly simplifying the inspection process and improving installation efficiency.

[0044] By rotating the handwheel to drive the rotating shaft 37 to rotate, and by utilizing the limiting effect of the two threaded sections 35 with opposite thread directions and the guide rod 36, the two vertical plates 32 can be easily moved towards or away from each other, thereby quickly adjusting the distance between them. The operation is simple and easy to understand, requiring no complicated tools or professional skills. Operators can quickly complete the distance adjustment work, greatly improving work efficiency.
