Description

Technical Field

[0001] This application relates to the field of lithium battery separator slitting technology, specifically to a lithium battery separator slitting machine. Background Technology

[0002] Lithium-ion battery separator slitting refers to the process of cutting a rolled-up separator into separator sheets of appropriate width. Specifically, a separator slitting machine uses vertical blades to cut a roll of separator material of a certain width into several narrower separator sheets.

[0003] An existing patent (publication number: CN216836468U) discloses a lithium battery separator slitting machine, including a processing base. A slitting bracket is provided on the upper end of the processing base, and a lifting mechanism is provided on the slitting bracket. An installation rod is connected to the lifting mechanism, and multiple installation seats are connected to the installation rod. This device uses a fixing mechanism to detach the installation pin from the installation seat, at which point the slitting blade is separated from the installation seat. When replacing with a new slitting blade of another specification, the fixing mechanism is operated in the same way, and the installation pin is aligned with the insertion slot and inserted. The slitting blade is fixed by the cooperation of the fixing mechanism, the limiting slot, and the fixing transverse slot. The installation and disassembly of the slitting blade are very simple and convenient, eliminating the need for heavy and numerous screw and bolt installation and disassembly operations. This not only greatly reduces the labor intensity of manual labor but also significantly improves replacement efficiency, which is beneficial for separator processing.

[0004] The aforementioned diaphragm slitting machine positions the mounting base using fastening bolts and threaded holes. However, due to the certain gap between the threaded holes, the lateral position adjustment of the mounting base and the slitting blade is limited, preventing them from being moved to any arbitrary position. This affects the adjustment and use of the slitting blade and leaves room for improvement. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a lithium battery separator slitting machine, which has the advantages of being able to move the slitting blade laterally as needed, adjust the position of the slitting blade, and move the slitting blade to any position, thus avoiding limitations in the adjustment of the slitting blade position. This solves the problem that the position adjustment of the slitting blade in existing separator slitting machines is limited by the spacing of the threaded holes, which has a certain impact on the adjustment and use of the slitting blade.

[0006] To achieve the above objectives, this application provides the following technical solution: a lithium battery separator slitting machine, comprising a base plate, a bracket fixedly connected to the upper surface of the base plate, a top plate inside the bracket, a fixing plate fixedly connected to one end of the bottom surface of the top plate, two sliding rods fixedly inserted inside the fixing plate, mounting seats equidistantly arranged slidably connected to the outer circumferential surfaces of the two sliding rods, a first T-slot opened inside each mounting seat, a slidable blade slidably connected inside the first T-slot, a motor provided on the upper surface of each mounting seat, a gear fixedly connected to the output end of the motor, a rack fixedly connected to the bottom surface of the top plate, the gear meshing with the rack, a second T-slot opened at the end of the top plate away from the fixing plate, a disassembly plate slidably connected inside the second T-slot, the disassembly plate slidably sleeved with the outer circumferential surface of the sliding rod through an internal through hole, a positioning ring threadedly connected to the outer circumferential surface of each sliding rod, and an operation window opened at the end of the bracket near the disassembly plate.

[0007] The above solution addresses the limitation imposed by the threaded hole spacing on the slitting blade of the existing diaphragm slitting machine during position adjustment, which affects the adjustment and use of the slitting blade. By driving the gear with a motor to rotate, the gear meshes with the rack, thereby moving the mounting base and the slitting blade laterally, adjusting the position of the slitting blade and moving it to any position, thus avoiding the limitation on the position adjustment of the slitting blade.

[0008] Furthermore, the top of the slitting blade has a T-shaped structure, and the T-shaped structure at the top of the slitting blade is adapted to the first T-shaped groove.

[0009] With the above solution, the T-shaped structure at the top of the slitting blade can support the entire slitting blade, causing the slitting blade to slide laterally only inside the first T-slot, which facilitates the installation and removal of the slitting blade.

[0010] Furthermore, the motor is a worm gear reducer motor with a built-in worm gear transmission structure.

[0011] With the above solution, the output end of the worm gear reducer motor can self-lock when the power is off, thereby positioning the mounting base, preventing the mounting base from sliding easily, and improving the stability of the mounting base and the slitting blade.

[0012] Furthermore, the top of the disassembly plate has a T-shaped structure, and the T-shaped structure at the top of the disassembly plate is adapted to the second T-shaped groove.

[0013] With the above solution, the T-shaped structure at the top of the disassembly plate facilitates installation and disassembly inside the second T-slot, while also providing longitudinal support to improve the overall stability of the disassembly plate.

[0014] Furthermore, each of the mounting bases has a side plate on one side, and each side plate has three positioning rods inside. The outer circumferential surfaces of the positioning rods are slidably inserted into the mounting base through through holes opened inside the mounting base. Each of the slitting blades has a positioning hole inside, and the outer circumferential surfaces of the positioning rods are slidably inserted into the slitting blade through the positioning hole.

[0015] The above solution facilitates the positioning and restriction of the slitting blade by inserting or removing the positioning rod from the positioning hole, thereby making the installation, disassembly, and maintenance of the slitting blade easier.

[0016] Furthermore, each of the mounting bases has two springs fixedly connected to its outer surface, and the other end of each spring is fixedly connected to the outer surface of the side plate.

[0017] With the above solution, the spring can restrict the side plate with its own elasticity, preventing the side plate and positioning rod from easily moving out of the positioning hole, and can drive the side plate and positioning rod to move back automatically, ensuring the stability of the slitting blade while also facilitating the installation and disassembly of the slitting blade.

[0018] Furthermore, a hydraulic cylinder is fixedly connected to the top of the bracket, and the output end of the hydraulic cylinder is fixedly connected to the upper surface of the top plate.

[0019] The above solution allows the top plate to be raised and lowered via a hydraulic cylinder, thereby adjusting the height of the slitting blade as needed.

[0020] Furthermore, four limiting rods are fixedly connected to the upper surface of the top plate, and the outer circumferential surface of each limiting rod is slidably inserted into the interior of the bracket.

[0021] By restricting the top plate through the above scheme, the top plate is forced to move longitudinally, thereby improving the stability of the top plate movement and thus improving the overall stability of the slitting machine during operation.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] This lithium battery separator slitting machine uses a motor to drive a gear to rotate, causing the gear to mesh with a rack, which in turn moves the mounting base and slitting blade laterally. This allows for adjustment of the slitting blade's position, moving it to any desired location without limitations. The machine incorporates a second T-slot, a disassembly plate, and a positioning ring to facilitate the installation and disassembly of the mounting base. This allows for easy adjustment of the number of mounting bases and slitting blades as needed, and also facilitates the disassembly and maintenance of the mounting base, improving the machine's practicality. This solves the problem of limited slitting blade position adjustment in existing separator slitting machines, which negatively impacts the machine's usability. Attached Figure Description

Detailed Implementation

[0032] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0033] Please see Figure 1 , Figure 3 and Figure 5This embodiment of a lithium battery separator slitting machine includes a base plate 1, a bracket 2 fixedly connected to the upper surface of the base plate 1, a top plate 3 inside the bracket 2, a fixing plate 4 fixedly connected to one end of the bottom surface of the top plate 3, two sliding rods 5 fixedly inserted inside the fixing plate 4, and mounting seats 6 equidistantly arranged slidably connected to the outer circumferential surfaces of the two sliding rods 5. Each mounting seat 6 has a first T-slot 7 inside, and a slidable cutting blade 8 is slidably connected inside the first T-slot 7. The upper surface of each mounting seat 6 is provided with... Motor 9, with gear 10 fixedly connected to the output end of motor 9, rack 11 fixedly connected to the bottom surface of top plate 3, gear 10 meshing with rack 11, a second T-slot 12 is provided at the end of top plate 3 away from fixed plate 4, disassembly plate 13 is slidably connected inside the second T-slot 12, disassembly plate 13 is slidably sleeved with the outer circumferential surface of slide rod 5 through the through hole opened inside, positioning ring 14 is threadedly connected to the outer circumferential surface of each slide rod 5, and operation window 21 is provided at the end of bracket 2 near disassembly plate 13.

[0034] Please see Figure 1 , Figure 2 and Figure 5 The top of the slitting blade 8 has a T-shaped structure, which is adapted to the first T-shaped groove 7. The T-shaped structure at the top of the slitting blade 8 can support the entire slitting blade 8, causing the slitting blade 8 to slide laterally only inside the first T-shaped groove 7, which facilitates the installation and disassembly of the slitting blade 8.

[0035] Please see Figure 2 , Figure 3 and Figure 5 Motor 9 is a worm gear reducer motor with a built-in worm gear transmission structure. The output end of the worm gear reducer motor can self-lock when the power is off, thereby positioning the mounting base 6, preventing the mounting base 6 from sliding easily, and improving the stability of the mounting base 6 and the slitting blade 8.

[0036] Please see Figure 1 , Figure 3 and Figure 4 The top of the disassembly plate 13 has a T-shaped structure, which is adapted to the second T-shaped groove 12. The T-shaped structure at the top of the disassembly plate 13 facilitates installation and disassembly inside the second T-shaped groove 12, and can also provide longitudinal support for itself, thereby improving the overall stability of the disassembly plate 13.

[0037] Please see Figure 3 , Figure 5 and Figure 6Each mounting base 6 has a side plate 15 on one side, and each side plate 15 has three positioning rods 16 inside. The outer circumferential surface of the positioning rods 16 is slidably inserted into the mounting base 6 through the through holes opened inside the mounting base 6. Each slitting blade 8 has a positioning hole 17 inside, and the outer circumferential surface of the positioning rods 16 is slidably inserted into the slitting blade 8 through the positioning holes 17. By inserting or removing the positioning rods 16 from the positioning holes 17, it is convenient to position and limit the slitting blade 8, thereby facilitating the installation, disassembly and maintenance of the slitting blade 8.

[0038] Please see Figure 2 , Figure 5 and Figure 6 Two springs 18 are fixedly connected to the outer surface of each mounting base 6. The other end of the spring 18 is fixedly connected to the outer surface of the side plate 15. The spring 18 can restrict the side plate 15 with its own elastic force, preventing the side plate 15 and the positioning rod 16 from easily moving out of the positioning hole 17. It can also drive the side plate 15 and the positioning rod 16 to move back automatically, ensuring the stability of the slitting blade 8 and facilitating the installation and disassembly of the slitting blade 8.

[0039] Please see Figure 1 and Figure 2 A hydraulic cylinder 19 is fixedly connected to the top of the bracket 2. The output end of the hydraulic cylinder 19 is fixedly connected to the upper surface of the top plate 3. The top plate 3 can be raised and lowered by the hydraulic cylinder 19, thereby adjusting the height of the slitting blade 8 as needed.

[0040] Please see Figure 1 and Figure 2 Four limiting rods 20 are fixedly connected to the upper surface of the top plate 3. The outer circumferential surface of each limiting rod 20 is slidably inserted into the inside of the bracket 2 to restrict the top plate 3, so that the top plate 3 always moves longitudinally, thereby improving the stability of the movement of the top plate 3 and thus improving the stability of the overall operation of the slitting machine.

[0041] This embodiment of a lithium battery separator slitting machine uses a motor 9 to drive a gear 10 to rotate, causing the gear 10 to mesh with a rack 11. This, in turn, moves the mounting base 6 and the slitting blade 8 laterally, allowing the position of the slitting blade 8 to be adjusted to any position. This avoids limitations on the position adjustment of the slitting blade 8. By providing a second T-slot 12, a disassembly plate 13, and a positioning ring 14, the mounting base 6 can be easily installed and disassembled. This facilitates the addition or reduction of the number of mounting bases 6 and slitting blades 8 as needed, and also facilitates the disassembly and maintenance of the mounting base 6, improving the practicality of the slitting machine. This solves the problem that the position adjustment of the slitting blade 8 in existing separator slitting machines is limited, which affects the adjustment and use of the slitting blade 8.

[0042] It should be noted that the outer circumferential surface of the positioning ring 14 is provided with equidistant anti-slip protrusions, which can increase friction with the hand and facilitate the rotation operation of the positioning ring 14.

[0043] The working principle of the above embodiments is as follows:

[0044] When the positions of the mounting base 6 and the slitting blade 8 need to be adjusted, the motor 9 can be started to drive the gear 10 to rotate. When the gear 10 rotates, it will mesh with the rack 11, thereby causing the mounting base 6 to slide laterally on the slide rod 5. The position of the slitting blade 8 can be adjusted arbitrarily as needed, thereby arbitrarily adjusting the slitting spacing, improving the flexibility and practicality of the slitting machine. The side plate 15 can be pulled to move the positioning rod 16 out of the positioning hole 17, removing the positioning restriction on the slitting blade 8. Then the slitting blade 8 can be removed from the first T-slot 7 for replacement or maintenance. When installing a new slitting blade 8, the new slitting blade 8 can be moved out of the first T-slot 7 for replacement or maintenance. The top of the cutter 8 slides into the first T-slot 7, causing the positioning rod 16 to automatically move back under the action of the spring 18 and insert into the positioning hole 17, thus completing the positioning of the new cutter 8. This is convenient and quick. The disassembly plate 13 can support the end of the slide rod 5 away from the fixed plate 4, improving the support capacity and stability of the slide rod 5, thereby improving the stability of the cutter 8 during operation. The positioning ring 14 can be rotated off, the disassembly plate 13 can be removed from the second T-slot 12, and the mounting seat 6 on the slide rod 5 can be removed or a new mounting seat 6 can be installed. The number of mounting seats 6 and cutters 8 can be increased or decreased according to different operational needs.
