Abstract
Description
Technical Field
[0001] This application relates to the field of take-up shaft technology, specifically a take-up shaft for a sheet rewinding machine. Background Technology
[0002] A sheet rewinding machine is a device used to mechanically wind sheet materials into rolls. It is widely used in various industries, such as paper, plastics, textiles, electronics, and printing, primarily to wind sheet materials into rolls for easy storage, transportation, and subsequent processing. The sheet rolls are placed on a take-up shaft, and the rotation of the take-up shaft drives the rolls to rotate, thus winding the sheet material.
[0003] When using existing take-up shafts, the roll is usually directly inserted into the take-up shaft for winding. However, the roll is prone to slipping when directly inserted into the take-up shaft, resulting in the roll not being secure and affecting the winding process.
[0004] Therefore, there is an urgent need for a take-up shaft for sheet rewinding machines to solve the problem of the roll easily sliding on the take-up shaft. Utility Model Content
[0005] To address the shortcomings of existing technologies, this application provides a take-up shaft for a sheet rewinding machine, which has the advantages of convenient and stable fixing of the roll and solves the problem of the roll easily sliding on the take-up shaft.
[0006] To achieve the above objectives, this application provides the following technical solution: a take-up shaft for a sheet rewinding machine, comprising a fixed plate, a driving device and a take-up shaft body, wherein the driving device is installed on the back side of the fixed plate, the take-up shaft body is installed on the output end of the driving device, a fixing mechanism is provided inside the take-up shaft body, and a support mechanism is provided on the fixed plate.
[0007] The fixing mechanism includes a drive motor, a threaded rod, a push block, and a pressure block. The drive motor is installed inside one end of the take-up shaft body. One end of the threaded rod is fixedly connected to the output end of the drive motor, and the other end of the threaded rod is rotatably connected to the inner side of the take-up shaft body. The push block is threadedly connected to the outer surface of the threaded rod. The pressure block is installed on the plate on the outer side of the take-up shaft body, and the bottom of the pressure block overlaps with the outer surface of the push block.
[0008] By adjusting the position of the push block, when the push block moves inward, it pushes the pressure block outward, pressing the pressure block against the inner surface of the drum, thus stabilizing and fixing the drum and improving the stability of the drum during winding.
[0009] Preferably, a limiting piece is welded to the outer surface of the pressure block, and the limiting piece is located inside the fixing piece.
[0010] Preferably, a guide plate is welded to the inner surface of the take-up shaft body, and the guide plate is slidably connected to the push block.
[0011] Preferably, the bottom of the pusher block has a slot that matches the guide plate.
[0012] Preferably, the support mechanism includes a fixing plate, a socket, and bolts. The fixing plate is slidably connected to the top of the fixing plate, and the bolts are installed at symmetrical positions on the top of the fixing plate, extending through the fixing plate into the socket.
[0013] Preferably, several groups of the insertion holes are linearly distributed on the top of the fixing plate.
[0014] In summary, this application includes at least one of the following beneficial effects:
[0015] 1. The sheet rewinding machine uses a take-up shaft. When the roll is sleeved on the take-up shaft body, by adjusting the position of the push block, when the push block moves inward, the push block squeezes the pressure block outward, so that the pressure block is pressed against the inner surface of the roll, and the roll is stably pressed and fixed, improving the stability of the roll when the sheet rewinding machine is wound up, and making the sheet winding more convenient.
[0016] 2. The sheet material rewinding machine uses a take-up shaft. The operator can push the fixing plate, which slides on the fixing plate, thereby changing the position of the take-up shaft body above the fixing plate. This allows for easy adjustment of the position of the take-up shaft body, making it convenient to take up the sheet material at different positions and facilitating the use of the take-up shaft.

[0022] 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.
[0023] Please see Figure 1-4 A take-up shaft for a sheet overcoating machine includes a fixed plate 1, a drive device 2, and a take-up shaft body 3. The drive device 2 is installed on the back side of the fixed plate 1, and the take-up shaft body 3 is installed at the output end of the drive device 2. When the drive device 2 is started, it drives the take-up shaft body 3 to rotate. When the roll is installed on the take-up shaft body 3, the take-up shaft body 3 rotates to drive the roll to take up the sheet material. The take-up shaft body 3 is provided with a fixing mechanism inside, and the fixed plate 1 is provided with a support mechanism.
[0024] Specifically, the fixing mechanism includes a drive motor 7, a threaded rod 8, a push block 9, and a pressure block 10. The drive motor 7 is installed inside one end of the take-up shaft body 3. One end of the threaded rod 8 is fixedly connected to the output end of the drive motor 7, and the other end of the threaded rod 8 is rotatably connected to the inner side of the take-up shaft body 3. The push block 9 is threadedly connected to the outer surface of the threaded rod 8. The pressure block 10 is installed on the plate on the outer side of the take-up shaft body 3. The bottom of the pressure block 10 overlaps with the outer surface of the push block 9. A limiting piece 11 is welded to the outer surface of the pressure block 10. The limiting piece 11 is located inside the fixing piece 1. A guide plate 12 is welded to the inner surface of the take-up shaft body 3. The guide plate 12 is slidably connected to the push block 9. A slot adapted to the guide plate 12 is opened at the bottom of the push block 9.
[0025] With the above technical solution, when the roll is sleeved on the take-up shaft body 3, the drive motor 7 is started. The drive motor 7 drives the threaded rod 8 to rotate. When the threaded rod 8 rotates, it drives the push block 9 to move, thereby adjusting the position of the push block 9. When the push block 9 moves inward, it pushes the pressure block 10 outward, so that the pressure block 10 is pressed against the inner surface of the roll, and the roll is stably pressed and fixed, improving the stability of the roll during winding and making it easier to wind up the sheet material. When the push block 9 moves, it slides on the top of the guide plate 12. The guide plate 12 limits the push block 9 to prevent it from rotating, and the limiting piece 11 prevents the pressure block 10 from sliding out of the take-up shaft body 3.
[0026] Specifically, the support mechanism includes a fixed plate 4, insertion holes 5 and bolts 6. The fixed plate 1 is slidably connected to the top of the fixed plate 4. The bolts 6 are installed at symmetrical positions on the top of the fixed plate 1. The bolts 6 penetrate the fixed plate 1 and extend into the insertion holes 5. Several sets of insertion holes 5 are linearly distributed on the top of the fixed plate 4.
[0027] With the above technical solution, during installation, the operator fixes the fixing plate 4 to the sheet rewinding machine with screws, and then pushes the fixing plate 1, which slides on the fixing plate 4, thereby changing the position of the take-up shaft body 3 above the fixing plate 1. This allows the position of the take-up shaft body 3 to be easily adjusted, making it convenient for the take-up shaft body 3 to wind up the sheet material at different positions, thus facilitating the use of the take-up shaft. After the take-up shaft body 3 is moved to the appropriate position, the operator uses bolts 6 to fix the fixing plate 1 to the fixing plate 4, allowing the take-up shaft to be easily installed.
[0028] When in use, by adjusting the position of the push block 9, when the push block 9 moves inward, the push block 9 presses the pressure block 10 outward, so that the pressure block 10 is pressed against the inner surface of the drum, and the drum is stably pressed and fixed, thereby improving the stability of the drum during winding.
[0029] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
