Description

Technical Field

[0001] This utility model relates to the technical field of PET monofilament production equipment, specifically a cutting device for PET monofilament production. Background Technology

[0002] PET (polyethylene terephthalate) monofilaments are widely used in industrial and consumer applications due to their high strength and temperature resistance. During monofilament production, the cutting device needs to meet the requirements of efficient blade changing and precise clamping; however, existing technologies have the following problems.

[0003] Traditional cutting blades are mostly fixed with bolts, requiring tools for disassembly, which is cumbersome and time-consuming. This is especially problematic when frequent blade changes are needed for PET monofilaments of different diameters, severely impacting production efficiency. Furthermore, during cutting, PET monofilaments are prone to shifting or deformation due to uneven tension or design flaws in the clamping device. Existing clamping mechanisms often rely on simple limiting plates, which are ill-suited to the flexibility of monofilaments, easily leading to cutting errors or material waste. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a cutting device for PET monofilament production, thus solving the aforementioned technical problems.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a cutting device for PET monofilament production, comprising a device body, a mounting frame protruding from the device body, a hydraulic telescopic cylinder mounted on the top of the mounting frame, a mounting plate connected to the output end of the hydraulic telescopic cylinder, two pressure plates slidably mounted on the mounting plate, a docking groove opened at the bottom of the mounting plate, a cutting blade inserted into the docking groove, a feeding frame protruding from the device body, a driving roller and a driven roller rotatably mounted on the feeding frame, a feeding trough opened on the device body, a receiving box slidably connected to the device body, and a rectangular hole opened on one side of the mounting frame.

[0008] Preferably, each of the two pressure plates is connected to two mutually symmetrical sliding rods at its top, and the sliding rods are slidably arranged on the mounting plate.

[0009] Preferably, the top of the sliding rod is integrally formed with a stop block, the size of which is larger than the size of the sliding hole on the mounting plate that is adapted to the sliding rod.

[0010] Preferably, a return spring is sleeved on the sliding rod, with one end of the return spring abutting against the mounting plate and the other end of the return spring abutting against the pressure plate.

[0011] Preferably, magnetic grooves are provided on both sides of the opening ends of the two docking grooves, and the same handle is adsorbed in the two magnetic grooves.

[0014] Compared with the prior art, this utility model provides a cutting device for PET monofilament production, which has the following beneficial effects: Through the cooperation of the pressure plate and docking groove, this utility model can drive the mounting plate to descend vertically when cutting PET monofilament. As the mounting plate descends, the two pressure plates connected to the mounting plate first contact the PET monofilament and press it firmly onto the main body of the device, thereby ensuring the cutting accuracy of the PET monofilament.

In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] Please see Figure 1-4 A cutting device for PET monofilament production includes a main body 1. A mounting frame 2 protrudes from the main body 1. A hydraulic telescopic cylinder 3 is mounted on the top of the mounting frame 2. A mounting plate 4 is connected to the output end of the hydraulic telescopic cylinder 3. Two pressure plates 9 are slidably mounted on the mounting plate 4. A docking groove 12 is opened at the bottom of the mounting plate 4. A cutting blade 13 is inserted into the docking groove 12. A feeding frame 10 protrudes from the main body 1. An active roller 14 and a driven roller 15 are rotatably mounted on the feeding frame 10. A feeding groove 8 is opened on the main body 1. A receiving box is slidably connected to the main body 1. A rectangular hole 18 is opened on one side of the mounting frame 2. Magnetic grooves are opened on both sides of the opening ends of the two docking grooves 12. The same handle 16 is attracted into the two magnetic grooves 17.

[0024] Through the cooperation of the pressure plate 9 and the docking groove 12, the mounting plate 4 can be driven to descend vertically by the hydraulic telescopic cylinder 3 when cutting PET monofilament. As the mounting plate 4 descends, the two pressure plates 9 connected to the mounting plate 4 first come into contact with the PET monofilament and press it firmly onto the main body 1 of the device, thereby ensuring the cutting accuracy of the PET monofilament. When it is necessary to replace the cutting blade 13, the handle 16 can be pulled out along the magnetic groove 17 to release the limit on the cutting blade 13. At this time, the cutting blade 13 can be pulled out along the opening direction of the docking groove 12, thereby achieving the purpose of quick replacement of the cutting blade 13.

[0025] Specifically, in this embodiment, the tops of the two pressure plates 9 are each connected to two symmetrical sliding rods 6, which are slidably arranged on the mounting plate 4.

[0026] The sliding rod 6 allows the pressure plate 9 to slide along the mounting plate 4.

[0027] Specifically, in this embodiment, the top of the sliding rod 6 is integrally formed with a stop 5, and the size of the stop 5 is larger than the size of the sliding hole on the mounting plate 4 that is adapted to the sliding rod 6.

[0028] By setting the stop 5, the movement range of the sliding rod 6 can be limited, preventing the sliding rod 6 from detaching from the mounting plate 4.

[0029] Specifically, in this embodiment, a return spring 7 is sleeved on the sliding rod 6. One end of the return spring 7 abuts against the mounting plate 4, and the other end of the return spring 7 abuts against the pressure plate 9.

[0030] With the reset spring 7 provided, when the hydraulic telescopic cylinder 3 drives the mounting plate 4 to descend vertically and the two pressure plates 9 come into contact with the PET monofilament and press it against the main body 1, the pressure plates 9 slide towards the mounting plate 4 through the sliding rod 6 and squeeze the reset spring 7. Thus, when the cutting is completed and the hydraulic telescopic cylinder 3 drives the mounting plate 4 to rise, the elastic potential energy of the reset spring 7 causes the pressure plates 9 to automatically reset.

[0031] Specifically, in this embodiment, the drive roller 14 and the driven roller 15 on the feeder 10 are both connected to a drive gear 19 and a driven gear 20, respectively. The drive gear 19 and the driven gear 20 mesh with each other. A servo motor 11 is installed on the feeder 10, and the output shaft of the servo motor 11 is installed on the drive gear 19.

[0032] Through the cooperation of the servo motor 11, the drive gear 19 and the driven gear 20, the servo motor 11 drives the drive gear 19 to rotate during use, which in turn drives the driven gear 20 to rotate, thereby realizing the rotation of the drive roller 14 and the driven roller 15. The PET monofilament can be fed through the drive roller 14 and the driven roller 15.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
