Description

Technical Field

[0001] This utility model relates to the field of polyethylene processing, and in particular to a winding device for polyethylene fiber production. Background Technology

[0002] Polyethylene fiber, a high-performance synthetic fiber, is produced from polyethylene through melt spinning. In the production process of polyethylene fiber, winding is a crucial step that determines the quality of the finished fiber. However…

[0003] Traditional winding methods mainly rely on manual operation, which has prominent problems such as high labor intensity and low winding efficiency.

[0004] As shown in patent publication CN210438189U, its structure includes components such as a base plate, a drive motor, a lower turntable, a support column, a top plate, an electric telescopic rod, and an upper turntable. This device drives the winding drum to rotate via a motor, while simultaneously using an electric telescopic rod to control the lifting and lowering of the upper turntable, thus clamping and fixing the winding drum. While such devices reduce manual labor to some extent, the steps for fixing and disassembling the winding are cumbersome, hindering production efficiency. Therefore, this solution proposes a winding device for polyethylene fiber production. Utility Model Content

[0005] This utility model proposes a winding device for polyethylene fiber production, which solves the problem of inconvenient disassembly and assembly of the winding shaft in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A winding device for producing polyethylene fibers includes a processing table and a winding shaft. The top surface of the processing table is rotatably connected to a mounting plate, and the top surface of the mounting plate is equipped with a plurality of clamping mechanisms for fixing the winding shaft.

[0008] The top surface of the mounting plate is provided with multiple mounting slots for mounting the clamping mechanism. The clamping mechanism includes a movable plate that slides in the mounting slot, a turntable that is rotatably connected to the top surface of the movable plate via a fixed shaft, a mounting plate that is fixed to the top surface of the movable plate, a top plate that is mounted on one side of the mounting plate, and a pressure plate that is rotatably connected to the bottom surface of the top plate. The pressure plate is located directly above the turntable, and a clamping space for clamping the roll is formed between the pressure plate and the turntable.

[0009] The mounting plate is equipped with a linkage component for driving the pressure plate to move when the movable plate moves along the length of the mounting groove, so as to adjust the size of the clamping space.

[0010] The top surface of the processing table is also equipped with a transmission mechanism for driving the turntable to rotate.

[0011] The above technical solution not only facilitates the fixing and disassembly of the roll, but also reduces the difficulty of operation and effectively improves the winding efficiency by setting multiple clamping mechanisms.

[0012] As a further improvement to the above solution, both long sides of the movable plate are slidably connected to the mounting groove via connectors. Both long sides of the mounting groove are provided with sliding grooves for installing connectors. The connectors include a sliding rod fixed inside the sliding groove along its length and a sliding sleeve movably sleeved around the sliding rod. One side of the sliding sleeve is fixedly connected to the long side of the movable plate.

[0013] The above technical solution enables the movable plate to move stably within the mounting slot.

[0014] As a further improvement to the above solution, a spring is movably sleeved on the outer periphery of the slide rod, one end of the spring is fixedly connected to one end of the slide sleeve, and the other end of the spring is fixedly connected to one side of the inner wall of the slide groove.

[0015] The above technical solution allows the spring force to drive the movable plate to automatically return to its original position.

[0016] As a further improvement to the above solution, the mounting plate is provided with a connecting groove along its length. The linkage component includes a screw rotatably connected in the connecting groove, a movable plate threaded around the outer periphery of the screw, and a fixed rack fixed to the bottom of the mounting groove. The bottom of the screw extends to the lower part of the movable plate and is fixed with a linkage gear that meshes with the fixed rack.

[0017] The above technical solution enables the movable plate to automatically drive the screw to rotate when it moves, thereby achieving the purpose of adjusting the clamping space size by moving the movable plate.

[0018] As a further improvement to the above solution, the bottom of the fixed shaft extends to the bottom of the movable plate and is fixed with a driven gear. The transmission mechanism includes an L-shaped movable table on the top surface of the processing table, a drive motor mounted on the top surface of the short end of the movable table, and a telescopic component mounted on the top surface of the processing table for driving the movable table to move. The output shaft of the drive motor is sleeved with a drive gear that cooperates with the driven gear to drive the driven gear to rotate after it meshes with the driven gear. A push rod is fixed on the outer wall of the long end of the movable table near the mounting plate to abut against the movable plate after the driven gear meshes with the drive gear.

[0019] The above technical solution can not only drive the turntable to rotate, but also drive the movable plate to move after the top rod abuts against the movable plate.

[0020] As a further improvement to the above solution, a limiting post for inserting a reel is fixed on the top surface of the turntable, a limiting piece is fixed on the outer periphery of the limiting post, and a limiting groove that matches the limiting piece is opened on the inner ring of the reel.

[0021] The above technical solution utilizes a limiting plate that is locked in a limiting groove, thereby driving the scroll to rotate synchronously when the turntable rotates.

[0022] As a further improvement to the above solution, the bottom surface of the pressure plate is fixed with an insert rod that is coaxially arranged with the limiting post, and the insert rod matches the inner ring of the scroll. Multiple anti-slip protrusions are fixed on the outer periphery of the insert rod.

[0023] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0024] 1. The clamping mechanism facilitates the disassembly and fixing of the roll, making it convenient for operators to install empty rolls and remove finished rolls. In addition, the installation plate and multiple clamping mechanisms allow for the simultaneous disassembly of another finished roll while one roll is being wound, thereby improving work efficiency.

[0025] 2. Through the cooperation between the transmission mechanism and the linkage components, the extension of the telescopic component can drive the movable plate to move towards the center of the mounting plate while the driving gear and the driven gear are meshed. This reduces the clamping space and automatically clamps the roll placed on the turntable. The spring, on the other hand, automatically drives the movable plate to move away from the center of the mounting plate during the retraction of the telescopic component, thereby loosening the roll.

[0033] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0034] Example 1:

[0035] Please combine Figures 1-5 This embodiment of a winding device for producing polyethylene fibers includes a processing table 1 and a winding shaft 13. The top surface of the processing table 1 is provided with a mounting plate 2. A rotating shaft 26, which is rotatably connected to the top surface of the processing table 1, is fixed at the center of the bottom surface of the mounting plate 2. A transmission motor for driving the rotating shaft 26 to rotate is installed inside the processing table 1. A PLC control panel 12 connected to the transmission motor is installed on the front of the processing table 1. The output shaft of the transmission motor is connected to the bottom of the rotating shaft 26. The transmission motor is started through the PLC control panel 12, so that the rotation of the transmission motor can drive the rotating shaft 26 to rotate, thereby achieving the purpose of driving the mounting plate 2 to rotate.

[0036] Multiple clamping mechanisms for fixing the roll 13 are installed on the top surface of the mounting plate 2. The processing table 1 is provided with a winding position corresponding to the clamping mechanism. After the clamping mechanism clamps the roll 13 and moves to the winding position with the rotation of the mounting plate 2, the polyethylene is wound onto the roll 13 for winding. The multiple clamping mechanisms are provided so that while the roll 13 in the winding position is winding the polyethylene, the empty roll 13 can be installed on other empty clamping mechanisms in advance. This makes it convenient to rotate the mounting plate to the winding position in time after the roll 13 is wound on the winding position, thereby improving the processing efficiency.

[0037] The top surface of the mounting plate 2 has multiple mounting slots 17 for mounting the clamping mechanism. The clamping mechanism includes a movable plate 3 slidably connected to the mounting slot 17, a turntable 4 rotatably connected to the top surface of the movable plate 3 via a fixed shaft, a mounting plate 6 fixed to the top surface of the movable plate 3, a top plate 5 mounted on one side of the mounting plate 6, and a pressure plate 27 rotatably connected to the bottom surface of the top plate 5. The pressure plate 27 is located directly above the turntable 4, and a clamping space for clamping the scroll 13 is formed between the pressure plate 27 and the turntable 4. The top surface of the turntable 4 is fixed with a limiting post 20 for inserting the scroll 13. A limiting piece is fixed to the outer periphery of the limiting post 20. The inner ring of the scroll 13 has a limiting groove that matches the limiting piece. The long sides of both sides of the movable plate 3 are slidably connected to the mounting slot 17 via connectors. The mounting groove 17 has sliding grooves 25 on both long sides for installing connectors. The connectors include a sliding rod 23 fixed inside the sliding groove 25 along its length and a sliding sleeve 24 movably sleeved on the outer periphery of the sliding rod 23. One side of the sliding sleeve 24 is fixed to the long side of the movable plate 3. The connectors allow the movable plate 3 to move stably within the mounting groove 17. When fixing the roller 13, the roller 13 is inserted into the limiting post 20 and the limiting plate is aligned with the limiting groove, so that the roller 13 can rotate when the turntable 4 rotates. After inserting the roller 13 outside the limiting post 20, the height of the pressure plate 27 is adjusted so that the pressure plate 27 presses on the top of the roller 13, thereby preventing the roller 13 from falling off the limiting post 20 when rotating.

[0038] The mounting plate 6 is equipped with a linkage assembly for driving the pressure plate 27 to move when the movable plate 3 moves along the length of the mounting groove 17, thereby adjusting the clamping space. The mounting plate 6 has a connecting groove 22 extending along its length. The linkage assembly includes a screw 21 rotatably connected to the connecting groove 22, a movable plate 14 threaded onto the outer periphery of the screw 21, and a fixed rack 19 fixed to the bottom of the mounting groove 17. The bottom of the screw 21 extends below the movable plate 3 and is fixed with a linkage gear 18 that meshes with the fixed rack 19. When plate 3 moves towards the center of mounting plate 2 inside mounting slot 17, linkage gear 18 rotates forward under the action of fixed rack 19, thereby driving screw 21 to rotate forward. After screw 21 rotates forward, it will drive moving plate 14 to move downward, thereby causing top plate 5 and pressure plate 27 to drop, and the clamping space will become smaller. Conversely, when moving plate 3 moves away from the center of mounting plate 2, it will drive top plate 5 and pressure plate 27 to move upward, thereby increasing the clamping space. Thus, the purpose of adjusting the size of the clamping space is achieved by moving moving plate 3.

[0039] The top surface of the processing table 1 is also equipped with a transmission mechanism for driving the turntable 4 to rotate. The bottom of the fixed shaft extends to the bottom of the movable plate 3 and is fixed with a driven gear 15. The transmission mechanism includes an L-shaped movable table 9 on the top surface of the processing table 1, a drive motor 8 installed on the top surface of the short end of the movable table 9, and a telescopic member 11 installed on the top surface of the processing table 1 for driving the movable table 9 to move. The output shaft of the drive motor 8 is sleeved with a drive gear 10 that cooperates with the driven gear 15 to drive the driven gear 15 to rotate after it meshes with the driven gear 15. The long end of the movable table 9 is fixed with a push rod 7 on the outer wall of the side near the mounting plate 2 for abutting against the movable plate 3 after the driven gear 15 meshes with the drive gear 10. When it is necessary to drive the winding shaft 13 located at the take-up position to rotate, the telescopic member 11 is activated to extend. After the telescopic member 11 extends, it drives the movable table 9 to move closer to the mounting plate 2. As the moving plate 9 moves closer to the side of the mounting plate 2, the drive gear 10 gradually approaches the driven gear 15. After the drive gear 10 meshes with the driven gear 15, one end of the push rod 7 immediately abuts against the outer wall of the movable plate 3. Then, as the telescopic member 11 continues to extend, the push rod 7 pushes the movable plate 3 to move closer to the center of the mounting plate 2. During this process, the linkage component operates, thereby driving the pressure plate 27 to descend until the pressure plate 27 presses against the top of the roll 13 and then the telescopic member 11 stops, thereby clamping the roll. Then the drive motor 8 is started. After the drive motor 8 rotates, it drives the drive gear 10 to rotate, and the drive gear 10 then drives the driven gear 15 to rotate, ultimately achieving the purpose of driving the turntable 4 and the roll 13 to rotate. The polyethylene will also be gradually wound up on the surface of the roll 13 as the roll 13 rotates.

[0040] In this embodiment, the telescopic member 11 is an electric telescopic rod, and the output end of the telescopic member 11 is fixedly connected to the outer wall of the long end of the moving platform 9. The input end of the telescopic member 11 is connected to the output end of the PLC control panel 12. The telescopic member 11 can be controlled to extend and retract through the PLC control panel 12.

[0041] In this embodiment, a rod 16 coaxially arranged with the limiting post 20 is fixed on the bottom surface of the pressure plate 27, and the rod 16 matches the inner ring of the scroll 13. Multiple anti-slip protrusions are fixed on the outer periphery of the rod 16. During the process of the pressure plate 27 pressing against the top of the scroll 13, the rod 16 will first insert into the inner side of the scroll 13 during the descent of the pressure plate 27, thereby further stabilizing the scroll 13. The protective protrusions increase the friction between the rod 16 and the inner wall of the scroll 13, so that the scroll 13 will not easily shake or detach during rotation.

[0042] Example 2:

[0043] Combination Figure 5Based on Embodiment 1, this embodiment further improves upon the following: a spring is movably sleeved on the outer periphery of the slide rod 23. One end of the spring is fixedly connected to one end of the slide sleeve 24, and the other end of the spring is fixedly connected to the inner wall of one side of the slide groove 25. The spring is designed so that the movable plate 3 compresses the spring as it moves toward the center of the mounting plate 2. When the telescopic member 11 retracts, the compressed spring will return to its original shape, thereby driving the slide sleeve 24 and the movable plate 3 to move automatically away from the center of the mounting plate 2. This automatically increases the clamping space, thereby facilitating the automatic release of the clamped roll 13 and making it easier for the operator to remove the roll from the clamping mechanism.

[0044] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
