Its manufacturing process requires extremely high precision, necessitating precise control of stretching, heat treatment, and other stages to ensure uniform film thickness and consistent performance. It is widely used in power electronics, new energy vehicles, and communications. In power electronics, it is used for filtering and energy storage circuits; in new energy vehicles, it is a key component in battery management systems and motor drive systems; and in communication equipment, it ensures stable signal transmission. As the electronics industry develops towards miniaturization and high performance, the market demand for polypropylene ultrathin capacitor film continues to grow due to its unique advantages, becoming an important force driving the advancement of electronic technology. During production, it is also wound up using a winding device.

[0003] However, in the existing technology, during the winding process of polypropylene ultrathin capacitor film using a winding device, wrinkles are easily generated due to uneven tension or external interference, which greatly affects the winding quality. Summary of the Invention

[0004] The purpose of this invention is to provide an anti-wrinkle mechanism for winding ultrathin polypropylene capacitor film, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a wrinkle-resistant mechanism for winding ultra-thin polypropylene capacitor film, comprising a support platform, a connecting column fixedly connected to the upper end of the support platform, a first motor disposed at the bottom of the inner part of the connecting column, a rotating shaft disposed at the output end of the first motor, a lead screw fixedly connected to one end of the rotating shaft, guide grooves being provided on both sides of the inner part of the connecting seat, guide blocks being slidably connected inside the guide grooves, ball bearings being disposed inside the guide blocks, an adjusting column being fixedly connected to one side of the guide blocks, a screw groove being provided inside the adjusting seat, and a top plate being fixedly connected to the upper end of the adjusting column.

[0006] Preferably, a first support plate is fixedly connected to the upper edge of the support platform, a first connecting rod is provided inside the first support plate, a traction roller is fixedly connected to one end of the first connecting rod, a second support plate is fixedly connected to the upper end of the support platform away from the first support plate, an arc-shaped block is fixedly connected to the front side of the second support plate, a second motor is provided inside the arc-shaped block, and an output roller is provided at the output end of the second motor.

[0007] The above solution achieves the following technical effects: By activating the first motor, the first motor drives the lead screw to rotate. Under the action of its external thread, the adjusting column moves downward along the inner side of the connecting column, and the top plate descends along with it. At this time, the pressure roller will be in close contact with the upper end of the capacitor diaphragm. Under the continuous output of the first motor, the tension of the capacitor diaphragm increases. Similarly, the first electric drive lead screw rotates in the opposite direction, and the adjusting column then drives the top plate to move upward. The pressure roller returns to its original position and is ready for reuse. In addition, during the lifting and lowering of the pressure roller, the guide block slides inside the guide groove. Under the action of the guide block, the stability of the pressure roller during lifting and lowering can be improved, and the ball bearings inside the guide block can further improve the smoothness of lifting and lowering.

[0008] Preferably, a connecting plate is fixedly connected to the lower end of the top plate near the adjusting column, a short block is fixedly connected to the front side of the connecting plate, and an electric push rod is provided on one side of the short block; The other end of the electric push rod is provided with a toothed plate, and a slider is fixedly connected to the rear side of the toothed plate. A sliding groove is opened inside the connecting plate, and a bearing is provided inside the connecting plate near the sliding groove. A rotating rod is fixedly connected to the inner ring of the bearing, and a gear is fixedly connected to one end of the rotating rod.

[0009] The above solution achieves the following technical effects: by activating the electric push rod, the electric push rod pushes the toothed plate to one side. Under the meshing of the gears, the rotating rod begins to rotate. During the rotation of the rotating rod, the pressure roller also rotates together, thereby changing the angle of the pressure roller. In addition, the electric push rod can rely on its own mechanical preload to prevent the toothed plate from retracting, avoid gear reversal, and ensure the fixed angle of the pressure roller. The slide groove and slider can improve the stability of the toothed plate when driving the gear to rotate.

[0010] Preferably, a fixed base is fixedly connected to the rear end of the rotating rod, and slots are provided on both sides of the fixed base. An installation block is provided inside the fixed base, and a stabilizing plate is fixedly connected to the lower end of the installation block. A fixed plate is fixedly connected to the lower end of the stabilizing plate, and a stabilizing block is fixedly connected to the lower end of the fixed plate. A pressure roller is provided on one side of the stabilizing block.

[0011] Preferably, the mounting block has a telescopic rod inside, a first spring is sleeved on the outside of the telescopic rod, a movable block is fixedly connected to one end of the telescopic rod, and a locking block is fixedly connected to the left side of the movable block; A fixing rod is fixedly connected inside the mounting block near the telescopic rod. A slip ring is provided inside the fixing rod. A locking block is fixedly connected to one side of the slip ring, and a second spring is provided on the other side of the slip ring.

[0012] The above solution achieves the following technical effects: By pushing the locking block, the locking block moves the moving block to one side and compresses the first spring with the telescopic rod. During this process, the locking block disengages from the slot and pulls down the fixing plate. The fixing plate then slides the mounting block out of the fixed seat, allowing the pressure roller to be disassembled for maintenance. Similarly, during installation, the mounting block is slid into the fixed seat. Once it reaches the preset position, the first spring rebounds and pushes the moving block to move in the opposite direction. The locking block then passes through the slot again, achieving the installation and fixation of the pressure roller. The second spring and slip ring further increase the speed at which the locking block passes through the slot, improving installation efficiency.

[0013] Preferably, the internal thread of the adjusting column is adapted to the external thread of the lead screw.

[0014] Preferably, the number of mounting blocks is two sets, and they are symmetrically arranged about the center line of the fixing plate.

[0015] Preferably, the slip ring slides inside the fixed rod in conjunction with a sliding rod, a moving block, a locking block, and a second spring.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. By activating the first motor, the first motor drives the lead screw to rotate. Under the action of its external thread, the adjusting column moves downward along the inner side of the connecting column, and the top plate descends along with it. At this time, the pressure roller will be in close contact with the upper end of the capacitor film. Under the continuous output of the first motor, the tension of the capacitor film increases. Similarly, the first electric drive lead screw rotates in the opposite direction, and the adjusting column then drives the top plate to move upward. The pressure roller returns to its original position, ready for reuse. In addition, during the lifting and lowering of the pressure roller, the guide block slides inside the guide groove. Under the action of the guide block, the stability of the pressure roller during lifting and lowering can be improved, and the ball bearings inside the guide block can further improve the smoothness of lifting and lowering. Through the components such as the first motor, lead screw, guide block, ball bearings, and adjusting column, the height of the pressure roller can be adjusted, thereby eliminating wrinkles caused by uneven tension or external interference during the winding process of the capacitor film, and also improving the winding quality.

[0017] 2. By activating the electric push rod, the electric push rod pushes the toothed plate to one side. Under the meshing of the gears, the rotating rod begins to rotate. During the rotation of the rotating rod, the pressure roller also rotates together, thereby changing the angle of the pressure roller. In addition, the electric push rod can rely on its own mechanical preload to prevent the toothed plate from retracting and avoid gear reversal, ensuring the fixed angle of the pressure roller. The slide and slider can improve the stability of the toothed plate when driving the gear to rotate. Through the electric push rod, toothed plate, slider, gear and other components, the angle of the rotating roller can be changed, thereby optimizing the pressure distribution of the pressure roller on the capacitor film, reducing local stress concentration, and ensuring the qualification rate of the finished product.

[0018] 3. By pushing the locking block, the locking block moves the moving block to one side and compresses the first spring with the telescopic rod. During this process, the locking block disengages from the slot and pulls down the fixing plate. The fixing plate then slides the mounting block out of the fixing seat, thus disassembling the pressure roller for maintenance. Similarly, during installation, the mounting block is slid into the fixing seat. Once it reaches the preset position, the first spring rebounds and pushes the moving block to move in the opposite direction. The locking block passes through the slot again, thus installing and fixing the pressure roller. The second spring and slip ring further improve the speed at which the locking block passes through the slot, increasing installation efficiency. Through the mounting block, telescopic rod, first spring, second spring, slip ring, and other components, the pressure roller can be quickly installed and removed, enabling maintenance during long-term use and reducing the difficulty of maintenance.

[0027] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding the present invention, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0028] Example 1 Please see Figures 1-7 This invention provides a technical solution: an anti-wrinkle mechanism for winding ultra-thin polypropylene capacitor film, comprising a support platform 1, a connecting column 2 fixedly connected to the upper end of the support platform 1, a first motor 3 disposed at the bottom of the inner part of the connecting column 2, a rotating shaft 4 disposed at the output end of the first motor 3, a lead screw 5 fixedly connected to one end of the rotating shaft 4, guide grooves 6 opened on both sides of the inner part of the connecting seat, guide blocks 7 slidably connected inside the guide grooves 6, ball bearings 8 disposed inside the guide blocks 7, an adjusting column 9 fixedly connected to one side of the guide blocks 7, a screw groove 10 opened inside the adjusting seat, a top plate 11 fixedly connected to the upper end of the adjusting column 9, and a first support plate 12 fixedly connected to the upper edge of the support platform 1. The internal structure is equipped with a first connecting rod 13, one end of which is fixedly connected to a traction roller 14. The upper end of the support platform 1 is fixedly connected to a second support plate 15 away from the first support plate 12. An arc-shaped block 16 is fixedly connected to the front side of the second support plate 15. A second motor 17 is installed inside the arc-shaped block 16. An output roller 18 is installed at the output end of the second motor 17. The internal thread of the adjusting column 9 is adapted to the external thread of the lead screw 5. The height of the pressure roller 34 can be adjusted through the components such as the first motor 3, lead screw 5, guide block 7, ball bearing 8, and adjusting column 9, thereby eliminating wrinkles caused by uneven tension or external interference during the winding process of the capacitor film, and also improving the winding quality.

[0029] Specifically, the first motor 3 is turned on, driving the lead screw 5 to rotate. Under the action of the external thread of the lead screw 5, the adjusting column 9 moves downward along the inner side of the connecting column 2, and the top plate 11 descends along with it. At this time, the pressure roller 34 will be in close contact with the upper end of the capacitor film. Under the continuous output of the first motor 3, the tension of the capacitor film increases. Similarly, the first electric drive lead screw 5 is rotated in the opposite direction, and the adjusting column 9 then drives the top plate 11 to move upward. The pressure roller 34 returns to its original position, ready for reuse. In addition, during the lifting and lowering of the pressure roller 34, the guide block 7 slides inside the guide groove 6. Under the action of the guide block 7, the stability of the pressure roller 34 during lifting and lowering can be improved, and the ball bearings 8 inside the guide block 7 can further improve the smoothness of lifting and lowering. Through the components such as the first motor 3, lead screw 5, guide block 7, ball bearings 8, and adjusting column 9, the height of the pressure roller 34 can be adjusted, thereby eliminating wrinkles caused by uneven tension or external interference during the winding process of the capacitor film, and also improving the winding quality.

[0030] Example 2 Please see Figures 1-7 This invention provides a technical solution: an anti-wrinkle mechanism for winding ultra-thin polypropylene capacitor film. A connecting plate 19 is fixedly connected to the lower end of the top plate 11 near the adjusting column 9. A short block 20 is fixedly connected to the front side of the connecting plate 19. An electric push rod 21 is provided on one side of the short block 20. A toothed plate 22 is provided at the other end of the electric push rod 21. A slider 26 is fixedly connected to the rear side of the toothed plate 22. A groove 27 is opened inside the connecting plate 19. A bearing 23 is provided inside the connecting plate 19 near the groove 27. A rotating rod 24 is fixedly connected to the inner ring of the bearing 23. A gear 25 is fixedly connected to one end of the rotating rod 24. The angle of the rotating roller can be changed through the components such as the electric push rod 21, toothed plate 22, slider 26, and gear 25, thereby optimizing the pressure distribution of the pressure roller 34 on the capacitor film, reducing local stress concentration, and ensuring the qualification rate of the finished product.

[0031] Specifically, when the electric push rod 21 is activated, it pushes the toothed plate 22 to one side. Under the meshing of the gear 25, the rotating rod 24 begins to rotate. During the rotation of the rotating rod 24, the pressure roller 34 also rotates together, thereby changing the angle of the pressure roller 34. In addition, the electric push rod 21 can use its own mechanical preload to prevent the toothed plate 22 from retracting and to prevent the gear 25 from reversing, thus ensuring the angle of the pressure roller 34 is fixed. The slide groove 27 and the slider 26 can improve the stability of the toothed plate 22 when driving the gear 25 to rotate. Through the components such as the electric push rod 21, toothed plate 22, slider 26, and gear 25, the angle of the rotating roller can be changed, thereby optimizing the pressure distribution of the pressure roller 34 on the capacitor film, reducing local stress concentration, and ensuring the qualification rate of the finished product.

[0032] Example 3 Please see Figures 1-7 This invention provides a technical solution: an anti-wrinkle mechanism for winding ultra-thin polypropylene capacitor film. A fixed base 28 is fixedly connected to the rear end of a rotating rod 24. Slots 29 are provided on both sides of the fixed base 28. An installation block 30 is provided inside the fixed base 28. A stabilizing plate 31 is fixedly connected to the lower end of the installation block 30. A fixed plate 32 is fixedly connected to the lower end of the stabilizing plate 31. A stabilizing block 33 is fixedly connected to the lower end of the fixed plate 32. A pressure roller 34 is provided on one side of the stabilizing block 33. A telescopic rod 35 is provided inside the installation block 30. A first spring 36 is sleeved on the outer side of the telescopic rod 35. A moving block 37 is fixedly connected to one end of the telescopic rod 35. A locking block 38 is fixedly connected to the left side of the moving block 37. A fixing rod 39 is fixedly connected inside the mounting block 30 near the telescopic rod 35. A slip ring 40 is provided inside the fixing rod 39. A locking block 38 is fixedly connected to one side of the slip ring 40, and a second spring 42 is provided on the other side of the slip ring 40. There are two sets of mounting blocks 30, which are symmetrically arranged about the center line of the fixing plate 32. The slip ring 40 slides inside the fixing rod 39 in cooperation with the second spring 42 through the sliding rod 41, the moving block 37, the locking block 38, and the second spring 42. The pressure roller 34 can be quickly installed and removed through the mounting block 30, telescopic rod 35, first spring 36, second spring 42, slip ring 40 and other components, so that maintenance can be carried out after long-term use, and the difficulty of maintenance can also be reduced.

[0033] Specifically, pushing the locking block 38 causes the moving block 37 to move to one side and compresses the first spring 36 with the telescopic rod 35. During this process, the locking block 38 disengages from the inside of the slot 29, pulling down the fixing plate 32. The fixing plate 32 then causes the mounting block 30 to slide out of the fixing seat 28, thus disassembling the pressure roller 34 for maintenance. Similarly, during installation, the mounting block 30 is slid into the inside of the fixing seat 28. After it reaches the preset position, the first spring 36 rebounds and pushes the moving block 37 to move in the opposite direction. The locking block 38 then passes through the slot 29 again, thus installing and fixing the pressure roller 34. The second spring 42 and the slip ring 40 further increase the speed at which the locking block 38 passes through the slot 29, improving installation efficiency. Through the mounting block 30, telescopic rod 35, first spring 36, second spring 42, slip ring 40, and other components, the pressure roller 34 can be quickly installed and removed, enabling maintenance during long-term use and reducing the difficulty of maintenance.

[0034] Working principle: When winding up the polypropylene ultra-thin capacitor film, the formed capacitor film is first passed through the traction roller 14 and the lead-out roller 18. These two rollers work together to smoothly and accurately guide the capacitor film into the winding path. Driven by the external winding equipment, the capacitor film moves continuously. It is worth mentioning that a second motor 17 is provided at the second support plate 15. Under its action, the winding speed of the capacitor film can be effectively improved. This series of operations work together to ensure the stability and order of the capacitor film winding process and improve the overall winding efficiency to meet production needs. During the winding process, the first motor 3 is turned on. The first motor 3 drives the lead screw 5 to rotate. Under the action of its external thread, the adjusting column 9 moves downward along the inner side of the connecting column 2, and the top plate 11 will descend with it. At this time, the pressure roller 34 will be in close contact with the upper end of the capacitor film. Under the continuous output of the first motor 3, the tension of the capacitor film increases. Similarly, the first electric drive lead screw 5 rotates in the opposite direction, and the adjusting column 9 then drives the top plate 11 to move upward. The pressure roller 34 returns to its original position and is ready for reuse. During the lifting and lowering of the pressure roller 34, the guide block 7 slides inside the guide groove 6. The guide block 7 improves the stability of the pressure roller 34 during lifting and lowering, while the ball bearings 8 inside the guide block 7 further enhance the smoothness of the lifting and lowering. The height of the pressure roller 34 can be adjusted via the first motor 3, lead screw 5, guide block 7, ball bearings 8, and adjusting column 9, thereby eliminating wrinkles caused by uneven tension or external interference during the winding process of the capacitor film, and also improving the winding quality. When the angle of the pressure roller 34 needs to be adjusted, the electric push rod 21 is activated. The electric push rod 21 pushes the toothed plate 22 to one side, and the gear 25 engages... With the cooperation of the rotating rod 24, the rotating rod 24 starts to rotate. During the rotation of the rotating rod 24, the pressure roller 34 will also rotate together, thereby changing the angle of the pressure roller 34. In addition, the electric push rod 21 can use its own mechanical preload to prevent the toothed plate 22 from retracting and prevent the gear 25 from reversing, thus ensuring the fixed angle of the pressure roller 34. The slide groove 27 and the slider 26 can improve the stability of the toothed plate 22 when driving the gear 25 to rotate. Through the components such as the electric push rod 21, toothed plate 22, slider 26, and gear 25, the angle of the rotating roller can be changed, thereby optimizing the pressure distribution of the pressure roller 34 on the capacitor film, reducing local stress concentration, and ensuring the qualification rate of the finished product. When the pressure roller 34 needs maintenance, push the locking block 38. The locking block 38 moves the moving block 37 to one side and compresses the first spring 36 with the telescopic rod 35. During this process, the locking block 38 will disengage from the inside of the locking groove 29, pulling down the fixing plate 32. The fixing plate 32 causes the mounting block 30 to slide out of the fixing seat 28, thus disassembling the pressure roller 34 for maintenance. Similarly, during installation, slide the mounting block 30 along the inside of the fixing seat 28 until it reaches the preset position. A spring 36 rebounds and pushes the moving block 37 to move in the opposite direction, and the locking block 38 passes through the locking groove 29 again, realizing the installation and fixation of the pressure roller 34. The setting of the second spring 42 and the slip ring 40 can further improve the speed at which the locking block 38 passes through the locking groove 29, thereby improving the installation efficiency. Through the installation block 30, telescopic rod 35, first spring 36, second spring 42, slip ring 40 and other components, the pressure roller 34 can be quickly installed and removed, thus enabling maintenance during long-term use and reducing the difficulty of maintenance.

For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and these variations still fall within the protection scope of the present invention.
