Description
Lead-acid battery separator cutting device Technical Field
[0001] This utility model relates to the field of lead-acid battery production technology, specifically to a lead-acid battery separator cutting device. Background Technology
[0002] Battery separators are an important component of lead-acid batteries and are currently widely used in PE separators for lead-acid batteries. Separators are generally wound on a reel and need to be cut to a fixed length.
[0003] Patent document CN207910011U discloses a PE separator cutting device for lead-acid batteries. The device involves fixing the separator to be cut on a worktable, rotating a handle, and using a sliding plate and rail to rotate a threaded rod that moves a threaded sleeve left and right to adjust the cutting wheel. When the cutting wheel is moved to a designated position, the motor is started, and the transmission shaft drives the cutting wheel to rotate. At this time, rotating the shaft causes a gear to move a horizontal plate back and forth via a rack to cut the separator. This device cannot cut separators to the small end suitable for batteries and is not suitable for fixed-length separator cutting.
[0004] Patent document CN213081625U discloses an automatic cutting device for soft polyethylene battery separators. This device achieves the feeding process by pushing a push rod, thus eliminating the need for direct hand contact with the material, making it safer and more practical. The rotating wheel presses and fixes the separator, and then the longitudinal cutting blade performs longitudinal cutting. The rotation of the rotating wheel changes the position of the limiting device, thereby pressing and fixing the separator and facilitating longitudinal cutting. After the separator is cut, manual unloading is required, which is inconvenient. In addition, PE separators are thin and have low hardness, and are generally wound on a material tray. This device cannot directly cut PE separators wound on the material tray. Summary of the Invention
[0005] The main purpose of this utility model is to provide a lead-acid battery separator cutting device that can directly cut the separators wound on the material tray to a fixed length, making it convenient to install the material tray with the separators wound on it.
[0006] To achieve the above objectives, the technical solution provided by this utility model is as follows:
[0007] A lead-acid battery separator cutting device includes a platform, a cutting assembly at the right end of the platform, a support assembly for mounting material trays at the left end of the platform, and a fixed-length conveying assembly in the middle of the platform. The cutting assembly includes a support frame fixed to the upper part of the platform. The support frame is inverted U-shaped. A lifting plate and a pressure plate are slidably arranged inside the support frame. Multiple vertical guide rods are fixed to the upper part of the pressure plate. The guide rods pass through the lifting plate and are slidably connected to the lifting plate. The lifting plate and the pressure plate are connected by multiple lower springs. The lifting plate and the upper part of the support frame are connected by multiple upper springs. A vertical upper telescopic rod is fixed to the upper part of the support frame. An upper plate is fixed to the upper part of the upper telescopic rod. A cutter is fixed to the upper plate. The left end of the cutter is flush with the right end of the platform. The cutter is located on the right side of the support frame. A top block is fixed to the left end of the cutter. The top block is located inside the support frame, and the lower end of the top block contacts the upper part of the lifting plate.
[0008] Specifically, a rubber pad is fixed to the lower end of the pressure plate.
[0009] Specifically, a double-ended screw is rotatably connected to the lower end of the support frame. The double-ended screw passes through the support frame and is arranged longitudinally. Limiting plates are provided on the threaded sections on both sides of the double-ended screw inside the support frame. The two limiting plates are symmetrically arranged front and back. The lower end of the limiting plate slides in contact with the upper end of the platform. The limiting plate is threadedly connected to the threaded section of the double-ended screw on one side.
[0010] Specifically, the fixed-length conveying assembly includes an installation groove on the platform, a lower roller is rotatably installed in the installation groove, an inverted U-shaped fixing frame is fixed at the upper end of the platform above the lower roller, an upper roller is rotatably installed in the fixing frame, a motor is fixed on the fixing frame, and the output shaft of the motor is concentrically and fixedly connected to the upper roller.
[0011] Specifically, the support assembly includes two support plates fixed to the left end of the platform. The two support plates are symmetrically arranged front and back, and each support plate is provided with a pin. A support block is provided below the two support plates. A groove is opened at the lower left end of the platform. The right end of the support block is slidably set in the groove. The left end face of the support block is a guide slope. An upper groove is opened at the upper right end of the support block. A horizontal lower telescopic rod is fixed in the groove. A fixing block is fixed at the left end of the lower telescopic rod and fixed in the upper groove.
[0012] Specifically, a guide roller is rotatably connected to the upper left side of the platform.
[0013] Specifically, the motor is a servo motor, which is electrically connected to the PLC controller through a driver. After the partition passes through the gap between the upper and lower rollers, the motor drives the upper roller to rotate, which can convey the partition to a fixed length.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0015] 1. The support assembly utilizes a coordinated design of a guide ramp, a lower telescopic rod, and a pin to achieve rapid positioning and automatic release of the material tray. After the material tray rolls to the support block, the lower telescopic rod retracts, causing the support block to exit. The material tray is then supported only by the pin and can rotate freely, significantly reducing the intensity of manual loading and unloading and improving continuous feeding efficiency.
[0016] 2. A servo motor combined with a PLC controller drives the upper roller, precisely controlling the conveying length through preset parameters to ensure consistent slitting dimensions of the partitions. The upper and lower roller clamping structure enhances the traction of the partitions and prevents slippage; the limiting plate adjusts the spacing through double-ended screws to achieve longitudinal alignment of the partitions, further ensuring cutting accuracy.
[0017] 3. The spring linkage system and guide structure of the cutting assembly allow the pressure plate to press down in two stages: first, the rubber pad flexibly presses the partition, and then the top block triggers the cutter to cut. This design can prevent the partition from shifting during cutting and also buffer mechanical impact, avoiding deformation or damage to the thin PE partition due to rigid pressure.
[0018] 4. The guide roller design prevents friction damage between the partition and the platform edge, making it especially suitable for applications with limited material tray clearance; the double-ended screw limiting mechanism supports rapid adjustment and is compatible with production needs for partitions of different widths. The overall structure balances protection and adaptability, expanding the equipment's application scenarios. Attached Figure Description

Detailed Implementation
[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0024] Example 1: Referring to Figures 1-3, the lead-acid battery separator cutting device includes a platform 1, a cutting component at the right end of the platform 1, a support component for mounting the material tray 6 at the left end of the platform 1, and a fixed-length conveying component in the middle of the platform 1.
[0025] The cutting assembly includes a support frame 10 fixed to the upper end of the platform 1. The support frame 10 is inverted U-shaped. A lifting plate 14 and a pressure plate 15 are slidably disposed inside the support frame 10. A rubber pad 25 is fixed to the lower end of the pressure plate 15. Multiple vertical guide rods 23 are fixed to the upper end of the pressure plate 15. The guide rods 23 pass through the lifting plate 14 and are slidably connected to the lifting plate 14. The lifting plate 14 and the pressure plate 15 are connected by multiple lower springs 24. The lifting plate 14 and the upper end of the support frame 10 are connected by multiple upper springs 22. A vertical upper telescopic rod 13 is fixed to the upper end of the support frame 10. An upper plate 12 is fixed to the upper end of the upper telescopic rod 13. A cutter 11 is fixed to the upper plate 12. The left end of the cutter 11 is flush with the right end of the platform 1. The cutter 11 is located on the right side of the support frame 10. A top block 21 is fixed to the left end of the cutter 11. The top block 21 is located inside the support frame 10, and the lower end of the top block 21 contacts the upper end of the lifting plate 14.
[0026] A double-ended screw 27 is rotatably connected to the lower end of the support frame 10. The double-ended screw 27 passes through the support frame 10 and is arranged longitudinally. Limiting plates 26 are provided on the threaded sections on both sides of the double-ended screw 27 inside the support frame 10. The two limiting plates 26 are symmetrically arranged front and back. The lower end of the limiting plate 26 slides in contact with the upper end of the platform 1. The limiting plate 26 is threadedly connected to the threaded section of the double-ended screw 27 on one side.
[0027] The fixed-length conveying assembly includes a mounting slot 20 formed on a platform 1. A lower roller 9 is rotatably mounted within the mounting slot 20. An inverted U-shaped fixing frame 7 is fixed to the upper end of the platform 1 above the lower roller 9. An upper roller 8 is rotatably mounted within the fixing frame 7. A motor is fixed to the fixing frame 7, and the output shaft of the motor is concentrically and fixedly connected to the upper roller 8. The motor is a servo motor, electrically connected to a PLC controller via a driver. After the partition passes through the gap between the upper roller 8 and the lower roller 9, the motor drives the upper roller 8 to rotate, enabling fixed-length conveying of the partition.
[0028] The support assembly includes two support plates 2 fixed to the left end of the platform 1. The two support plates 2 are symmetrically arranged front and back. A pin 3 is installed through each support plate 2. A support block 4 is installed below the two support plates 2. A groove 17 is opened at the lower left end of the platform 1. The right end of the support block 4 is slidably installed in the groove 17. The left end face of the support block 4 is a guide slope. An upper groove 16 is opened at the upper right end of the support block 4. A horizontal lower telescopic rod 18 is fixed in the groove 17. A fixing block 19 is fixed at the left end of the lower telescopic rod 18. The fixing block 19 is fixed in the upper groove 16.
[0029] When installing the material tray 6, the left end face of the support block 4 is a guide slope, which facilitates the material tray 6 to roll to the top of the support block 4. After the material tray 6 rolls to the top of the support block 4, the pin 3 on the support plate 2 is inserted into the inner hole of the material tray 6. Then, the lower telescopic rod 18 is activated. The lower telescopic rod 18 moves the support block 4 to the left through the fixing block 19. When the material tray 6 is above the upper groove 16, the lower end of the material tray 6 separates from the support block 4. At this time, the material tray 6 can rotate freely.
[0030] The partition plate of the discharge disc 6 passes between the upper roller 8 and the lower roller 9, and the partition plate passing between the upper roller 8 and the lower roller 9 passes between the two limiting plates 26. The double-ended screw 27 is rotated to adjust the distance between the two limiting plates 26 so that the two limiting plates 26 contact the two sides of the partition plate respectively, and the limiting plates 26 can limit the partition plate in the longitudinal direction.
[0031] The PLC controller controls the intermittent rotation of the motor, with a set number of revolutions per rotation. By adjusting the parameters of the PLC controller, the number of revolutions per motor rotation controls the distance the partition is conveyed to the right. After the motor is turned off, the upper telescopic rod 13 starts, driving the cutter 11 downwards via the upper plate 12. During the downward movement of the cutter 11, the top block 21 drives the lifting plate 14, pressure plate 15, and rubber pad 25 downwards. The upper spring 22 is stretched, and the rubber pad 25 compresses the partition. As the lifting plate 14 moves downwards, it compresses the lower spring 24. After the cutter 11 cuts the partition, the upper telescopic rod 13 drives the cutter 11 to reset. Under the elastic force of the lower spring 24 and the upper spring 22, the lifting plate 14 and pressure plate 15 return to their original positions. The cutter 11 moves downwards to cut the partition after the motor rotates a set number of revolutions, thus achieving fixed-length cutting of the partition.
[0032] Example 2: Based on Example 1, as shown in Figures 1-2, a guide roller 5 is rotatably connected to the upper left side of platform 1.
[0033] By setting guide roller 5, when the remaining partition in the material tray 6 is small, guide roller 5 can prevent the partition from rubbing against the upper left edge of the platform 1, thus preventing the partition from being scratched.
[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
