Description

Technical Field

[0001] This utility model relates to the field of cutting equipment, specifically a cutting equipment for the production of ultra-high molecular weight polyethylene composite fibers. Background Technology

[0002] Ultra-high molecular weight polyethylene (UHMWPE) composite fiber is a high-performance fiber material made by combining UHMWPE with other materials (such as carbon fiber, glass fiber, resin, etc.) through composite technology. It combines the unique properties of UHMWPE with the advantages of other materials and is widely used in fields such as high strength, lightweight, and wear resistance. In the production of UHMWPE composite fiber, cutting equipment is usually required to align and cut it for easy use and processing.

[0003] Existing cutting equipment typically uses blades to cut fibers, employing the mechanical force of carbide or ceramic blades to directly sever the fibers. This method is low-cost and suitable for low-strength fibers or small-batch production. However, this method causes the blades to wear out easily, requiring frequent replacements. The cuts are also prone to burrs or deformation. Currently, the blades are usually disassembled using screws and tools, which is not only inefficient but also affects subsequent production efficiency. Furthermore, the need for frequent replacements increases the burden and inconvenience on workers when changing blades. Utility Model Content

[0004] The purpose of this utility model is to provide a cutting device for the production of ultra-high molecular weight polyethylene composite fibers, so as to solve the problems mentioned in the background art and overcome its technical defects.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: It includes a conveying device, an adjusting mechanism inside the conveying device, a cutter assembly / disassembly mechanism inside the conveying device, a controller connected to the front of the conveying device, and a cutter assembly / disassembly mechanism including a housing. A fixing block is slidably connected inside the housing. A through groove is opened on the bottom surface of the housing. A cutting blade is connected to the bottom surface of the fixing block. Two guide grooves are opened inside the housing. Guide blocks are connected to both the front and back of the fixing block. A U-shaped plate is connected to the right side of the housing. Two limiting holes are opened on the right side of the U-shaped plate. Two positioning holes are opened on the right side of the fixing block. Two fixing holes are opened on the right side of the housing. Limiting rods are slidably connected inside the limiting holes, the positioning holes, and the fixing holes. Limiting plates are connected to the outer surfaces of the two limiting rods. A spring is sleeved on the outer surface of each limiting rod.

[0006] As a further embodiment of this utility model: the adjustment mechanism includes two support cylinders, each of the two support cylinders having a groove on one side close to each other, each groove having a bearing embedded inside, each bearing having a threaded rod connected to its inner ring, each support cylinder having a motor connected to its upper surface, and each groove having a support block slidably connected to its inner wall.

[0007] As a further embodiment of this utility model: the interior of each support block is threadedly connected to the outer surface of the threaded rod, and the end of each threaded rod away from the bearing passes through the support cylinder and extends to the outside of the support cylinder.

[0009] As a further embodiment of this utility model: the side of the cutting blade away from the fixing block passes through the through groove and extends to the outside of the outer shell, and the outer surface of each guide block is slidably connected to the inner wall of the guide groove.

[0010] As a further improvement of this utility model: the end of each spring near the U-shaped plate is connected to the outer surface of the U-shaped plate, and the end of each spring away from the U-shaped plate is connected to the outer surface of the limiting plate.

[0015] According to one embodiment of the present invention, in conjunction with the appendix Figs. 1 to 4 As shown.

[0016] A cutting device for producing ultra-high molecular weight polyethylene composite fibers includes a conveying device 1, an adjustment mechanism 3 inside the conveying device 1, a cutter assembly / disassembly mechanism 4 inside the conveying device 1, and a controller 2 connected to the front of the conveying device 1.

[0017] In this embodiment, the adjusting mechanism 3 includes two support cylinders 301. Each support cylinder 301 has a groove 302 on one side that is close to the other. A bearing 303 is embedded inside each groove 302. A threaded rod 304 is connected to the inner ring of each bearing 303. A motor 305 is connected to the upper surface of each support cylinder 301. A support block 306 is slidably connected to the inner wall of each groove 302. The cutter assembly / disassembly mechanism 4 includes a housing 401. A fixing block 402 is slidably connected inside the housing 401. A through groove 403 is formed on the bottom surface of the housing 401. A cutting blade 404 is connected to the bottom surface of the fixing block 402. Two guide grooves 405 are formed inside the housing 401. Guide blocks 406 are connected to both the front and back sides of the fixing block 402. A U-shaped plate 407 is connected to the right side of 401. Two limiting holes 408 are opened on the right side of the U-shaped plate 407. Two positioning holes 409 are opened on the right side of the fixing block 402. Two fixing holes 410 are opened on the right side of the outer shell 401. The interiors of the limiting holes 408, the positioning holes 409, and the fixing holes 410 are slidably connected to the limiting rods 411. The outer surfaces of the two limiting rods 411 are connected to the limiting plate 412. A spring 413 is sleeved on the outer surface of each limiting rod 411. Through the cooperation of the guide block 406 and the guide groove 405, the stability of the fixing block 402 when it is placed into the outer shell 401 can be increased. Through the design of the spring 413, the elasticity and extensibility of the spring 413 can effectively push the limiting plate 412 to move.

[0018] In this embodiment, the interior of each support block 306 is threadedly connected to the outer surface of the threaded rod 304. The end of each threaded rod 304 away from the bearing 303 passes through the support cylinder 301 and extends to the outside of the support cylinder 301. The right end of each threaded rod 304 away from the bearing 303 is connected to the output end of the motor 305. The outer surfaces of both support cylinders 301 are connected to the interior of the conveying device 1. The sides of the two support blocks 306 that are close to each other are connected to the outer surface of the outer shell 401. Through the cooperation of the support block 306 and the threaded rod 304, when the motor 305 drives the threaded rod 304 to rotate, the support block 306 can slide up and down on the inner wall of the groove 302 according to the direction of rotation of the threaded rod 304.

[0019] In this embodiment, the side of the cutting blade 404 away from the fixing block 402 passes through the through groove 403 and extends to the outside of the outer shell 401. The outer surface of each guide block 406 is slidably connected to the inner wall of the guide groove 405. The end of each spring 413 near the U-shaped plate 407 is connected to the outer surface of the U-shaped plate 407. The end of each spring 413 away from the U-shaped plate 407 is connected to the outer surface of the limiting plate 412. The right ends of the two limiting rods 411 are connected to a pull plate 414. The upper surface of the fixing block 402 is connected to a handle 415. The pull plate 414 makes it easy for the operator to pull the limiting plate 412 to move. The handle 415 makes it easy for the operator to lift the cutting blade 404 to move.

[0020] Working principle: When the cutting blade 404 needs to be replaced, first pull the pull plate 414. The pull plate 414 will drive the two limit rods 411 to move. At the same time, the limit rods 411 will drive the limit plate 412 to move and compress the spring 413. The limit rods 411 will be pulled out from the inside of the fixing hole 410 and the positioning hole 409 in sequence. Then, grasp the handle 415 and lift it upward, so that the cutting blade 404 and the fixing block 402 are pulled out from the inside of the outer shell 401 and the through groove 403. Then, lift the new handle 415 so that the new fixing block 402 is inserted. When the outer casing 401 is neutralized, the new cutting blade 404 will enter the outer casing 401 along with the new fixing block 402 and pass through the through groove 403. At the same time, the positioning hole 409 will automatically align with the fixing hole 410. Then, the pull plate 414 is released, the spring 413 will not be under pressure, and it will push the limiting plate 412 to move. When the limiting plate 412 moves, it will drive the limiting rod 411 to slide inside the limiting hole 408. At the same time, the limiting rod 411 will pass through the fixing hole 410 and the positioning hole 409 in sequence, thereby completing the replacement of the cutting blade 404.

[0021] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
