[0002] Perfluorosulfonic acid proton exchange membranes are solid polymer electrolytes with multiple stabilizations and high conductivity. The structure of its carbon-fluorine backbone and sulfonic acid groups endows it with high mechanical strength and good chemical stability. This membrane is a core component in hydrogen fuel cells and is also widely used in chlor-alkali industry, water electrolysis hydrogen production and other fields. Domestic enterprises have broken through the technological monopoly through independent research and development, and achieved full industrial chain coverage from raw materials to finished products, with an annual production capacity of one million square meters, providing a guarantee for the strategic security of the hydrogen energy industry. In the production process of slitting exchange membranes, it is difficult to conveniently and accurately adjust the slitting width of the take-up roller before slitting. Traditional adjustment methods often cannot guarantee the consistency of the slitting width, resulting in inconsistent product quality. Secondly, traditional adjustment structures may be relatively complex, occupy a lot of space, and are inconvenient to operate, maintain and debug, resulting in low efficiency in actual production. Furthermore, facing the production requirements of different specifications of exchange membranes, traditional methods are not easy to flexibly adjust the slitting quantity and width according to actual needs, which limits the automation level of the production line and cannot efficiently meet the diverse market demands.

[0016] 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.

[0017] Please see Figure 1-5 An embodiment of this utility model is provided: a perfluorinated proton exchange membrane roll cutting device, including a base plate 1 and a rotating block 35, wherein an adjustment mechanism 2 and a locking mechanism 3 are provided on the top of the base plate 1; The adjusting mechanism 2 includes a support plate 21 fixedly connected to the top surface of the base plate 1. A second support frame 22 is fixedly connected to the top of the base plate 1. A hollow tube 23 is rotatably connected to the inner wall of the second support frame 22. Several sliding grooves 24 are opened on the hollow tube 23. The several sliding grooves 24 are evenly distributed in a linear row on the outer wall of the hollow tube 23. Connecting rings 25 are slidably connected to the inner walls of the several sliding grooves 24. Cutting rings 26 are fixedly connected to the outer walls of the several connecting rings 25. Hinges 27 are fixedly connected to the inner walls of the several connecting rings 25. A hinge rod 28 is rotatably connected, and a hinge shaft 29 is rotatably connected between each of the two hinge rods 28. A positioning ring 291 is fixedly connected to the left side of the left connecting ring 25 and the right side of the right connecting ring 25. The two positioning rings 291 are slidably connected to the inner walls of the two slide grooves 24 respectively. A bidirectional threaded rod 292 is rotatably connected to the inner wall of the hollow tube 23. The bidirectional threaded rod 292 is threaded through the two positioning rings 291. A motor 231 is fixedly connected to the rear side of the support plate 21. The rear end of the hollow tube 23 is fixedly connected to the output end of the motor 231 through a coupling.

[0018] The locking mechanism 3 includes a knob 31 fixedly connected to the right end of the bidirectional threaded rod 292. A groove 32 is provided on the left side of the knob 31. A positioning block 33 is slidably connected to the inner wall of the groove 32. A threaded rod 34 is rotatably connected to the top of the positioning block 33. The top end of the threaded rod 34 extends to the top of the knob 31. The threaded rod 34 is threadedly connected to the knob 31. Several locking teeth 36 are provided on the contact surfaces of the positioning block 33 and the hollow tube 23. The locking teeth 36 are interleaved. Two support frames 11 are fixedly connected to the top of the base plate 1. An unwinding roller 12 is rotatably connected to the inner wall of the left support frame 11. A take-up roller 13 is rotatably connected to the inner wall of the right support frame 11. An exchange membrane 14 is wound around the outer wall of the unwinding roller 12. The exchange membrane 14 is in contact with the take-up roller 13 and several cutting rings 26 respectively.

[0019] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 Multiple cutting rings 26 are respectively fitted onto the outer wall of the hollow tube 23 through multiple positioning rings 291 and are slidably connected to the hollow tube 23. The multiple positioning rings 291 are evenly distributed in a linear row on the outer wall of the hollow tube 23 to form a whole cutting roller. The motor 231 drives the hollow tube 23 to rotate and cut the exchange membrane 14. Two support frames 11 are respectively welded to the top left and right sides of the base plate 1. While the exchange membrane 14 is wound on the outer wall of the unwinding roller 12, after the exchange membrane 14 is cut, multiple sets of cut exchange membranes 14 are wound on the winding roller 13 to form a complete cutting chain.

[0020] Working principle: With the adjustment mechanism 2, when the exchange membrane 14 is cut, it is pulled out from the unwinding roller 12. After being manually cut by multiple cutting rings 26, the cut sections of exchange membrane 14 are respectively wound onto the outer wall of the take-up roller 13. The motor 231 on the drive support plate 21 drives the hollow tube 23 to rotate, thereby causing the multiple cutting rings 26 on the hollow tube 23 to cut the exchange membrane 14. Before cutting, the double-threaded rod 292 can be rotated by turning the knob 31, thereby causing the left and right positioning rings 291 to drive the left connecting ring 25 and the right connecting ring 292. The connecting rings 25 move closer or further apart. Due to the cooperation of multiple hinge shafts 27, hinge rods 28 and hinge shafts 29, the distance between multiple cutting rings 26 can be adjusted simultaneously when the two positioning rings 291 on the left and right are close to each other. This allows for simultaneous adjustment of the cutting width of the take-up roller 13, ensuring the consistency of the cutting width. At the same time, the adjustment mechanism has a compact structure, is easy to operate, and is convenient to maintain and debug. It has a wide range of applications and can flexibly adjust the cutting quantity and width according to actual needs to meet the production requirements of different specifications of exchange membranes, significantly improving the automation level of the production line and the stability of product quality. With the locking mechanism 3 in place, after adjusting the spacing between the multiple cutting rings 26, the threaded rod 34 can be rotated by twisting the rotating block 35. This, in conjunction with the groove 32, allows the positioning block 33 to slide downward within the groove 32. The contact surfaces of the positioning block 33 and the hollow tube 23 are provided with multiple mutually compatible locking teeth 36, which interlock with each other, thereby positioning the bidirectional threaded rod 292 inside the hollow tube 23. This prevents the bidirectional threaded rod 292 from loosening inside the hollow tube 23 and further improves the stability after adjustment.
