[0001] The utility model relates to the technical field of polypropylene woven bags, and specifically relates to a winding device for producing polypropylene woven bags. Background Technique
[0002] A woven bag, also known as a snake skin bag, is a type of plastic bag used for packaging. Its raw materials are generally various chemical plastic raw materials such as polyethylene and polypropylene. When producing a woven bag made of high-strength polypropylene material, winding processing is required. The bag material is first wound around the surface of a roller for subsequent processing. Currently, a winding device for producing polypropylene woven bags is needed.
[0003] When the existing winding device winds, the woven bag material is fluffy. When using a single roller for winding, it is impossible to wind tightly, and the volume and thickness of the winding cannot be adjusted, which is inconvenient to use. In addition, the existing winding device also has some disadvantages to a certain extent. When the winding device is in use, the woven bag body is prone to tilting. The existing winding device usually does not have the function of limiting and preventing the deviation of the woven bag body. This makes it impossible to guide and block the woven bag body during the use of the winding device, resulting in the woven bag body not being accurately wound on the surface of the winding roller, and easily causing the phenomenon of the deviation of the woven bag body during the use of the winding device; when the winding device is in use, it is necessary to smooth and press the woven bag body on the surface of the winding roller. The existing winding device cannot smooth and press the woven bag body during use. This makes it impossible to tighten the woven bag body when it is wound on the surface of the winding roller, and cannot ensure the compactness of the winding device when winding the woven bag body; when the winding device is in use, it is necessary to disassemble and assemble the winding roller. The existing winding device is not convenient enough when disassembling and assembling the winding roller. This makes it inconvenient for the user to remove the winding roller from the inside of the support plate during the use of the winding device, making it inconvenient and smooth for the user to operate the winding device, and reducing the work efficiency.

Moreover, it enables the winding device to facilitate the user to remove the winding roller from the inside of the support frame plate for replacement treatment, making it more convenient and smooth for the user to operate the winding device, and having higher work efficiency;
[0014] By providing a guiding and anti - skewing mechanism, controlling the electric push rod inside the cylinder body to work.

When there is a large amount of woven bag body wound on the surface of the winding roller, at this time, the moving plate is adjusted up and down to the required position on the inner wall of the support plate. Under the action of the flattening plate, the woven bag body wound on the surface of the winding roller can be pressed and anti-loosened, realizing the function of the winding device to flatten and press the woven bag body on the surface of the winding roller.

[0026] During implementation, the winding roller 106 slides inside the guiding groove 32. Under the action of the guiding groove 32, the winding roller 106 is guided. At this time, the winding roller 106 drives the anti - detachment clamping member 33 away from the interior of the fixed cylinder 31. At this time, the winding roller 106 drives the first magnet 34 away from the surface of the second magnet 35, thereby pulling out the winding roller 106 and the woven bag body 103 from the interior of the support frame plate 102.

One end of the stretching spring 233 is fixed to the surface of the limiting plate 232.
[0028] During implementation, the electric push rod 21 inside the cylinder body 22 is controlled to work. Under the action of the electric push rod 21, the moving rod 234 slides inside the cylinder body 22. When the moving rod 234 moves, the moving rod 234 drives the guiding frame 231 to move into contact with the surface of the woven bag body 103. Under the elastic force of the stretching spring 233 inside the guiding frame 231, the limiting plate 232 is driven to move, so that the limiting plate 232 moves into contact with the surface of the woven bag body 103. Under the combined action of the guiding frame 231 and the limiting plate 232, the two sides of the woven bag body 103 are limited and smoothed, so as to realize the function of the winding device to limit and prevent deviation of the woven bag body 103.
[0029] Furthermore, as Figure 2 and Figure 5As shown in the figure, a flattening and winding mechanism 4 is provided on the surfaces of the support frame plate 102 and the woven bag body 103. The inside of the flattening and winding mechanism 4 includes a fixed frame 41, a flattening plate 42 and a flattening and winding group 43.

The fixed grooves 434 are slidably matched with the surface of the flattening plate 42.
[0030] During implementation, when the woven bag body 103 is wound around the surface of the winding roller 106, under the combined action of the telescopic column 432 and the elastic device 431 inside the fixed frame 41, the flattening plate 42 is driven to move, so that the flattening plate 42 slides inside the fixed groove 434. Under the action of the fixed groove 434, the flattening plate 42 is guided. Under the combined action of the telescopic column 432 and the elastic device 431 inside the fixed frame 41, the bottom of the flattening plate 42 is driven to move to be in contact with the surface of the woven bag body 103. Under the action of the flattening plate 42, both sides of the woven bag body 103 are flattened and pressed. When there is more woven bag body 103 wound around the surface of the winding roller 106, at this time, the moving plate 433 is adjusted up and down to the required position on the inner wall of the support frame plate 102. Under the action of the flattening plate 42, the woven bag body 103 wound around the surface of the winding roller 106 can be pressed and anti-loosened, so as to realize the function of flattening and pressing the woven bag body 103 on the surface of the winding roller 106 by the winding device.
[0031] Working principle: When in use, first place the device frame 1 at the designated position. The user winds one end of the woven bag body 103 around the surface of the winding roller 106. Subsequently, the surface of the rotating member 107 is connected to the rotating shaft of the motor. When the motor rotates, the motor drives the winding roller 106 to rotate on the inner wall of the support frame plate 102. At this time, the winding roller 106 drives the rotating member 107 and the rotating column 105 to rotate on the inner wall of the support frame plate 102 to wind the woven bag body 103. Under the combined action of the guiding column 104 and the anti-slip pad 108, the woven bag body 103 is guided.
[0032] Subsequently, the user operates the control button 101, causing the control button 101 to control the operation of the electric push rod 21 inside the cylinder body 22. Under the action of the electric push rod 21, the moving rod 234 is driven to slide inside the cylinder body 22. When the moving rod 234 moves, the moving rod 234 drives the guide frame 231 to move into contact with the surface of the woven bag body 103. Under the elastic force of the extension spring 233 inside the guide frame 231, the limiting plate 232 is driven to move, so that the limiting plate 232 moves into contact with the surface of the woven bag body 103. Under the combined action of the guide frame 231 and the limiting plate 232, the two sides of the woven bag body 103 are limited and smoothed, so as to realize the function of the winding device to limit and prevent the deviation of the woven bag body 103, so that the winding device can guide and block the woven bag body 103 during use, so that the woven bag body 103 can be accurately wound on the surface of the winding roller 106, avoiding the deviation of the woven bag body 103 during the use of the winding device.
[0033] Subsequently, when the woven bag body 103 is wound on the surface of the winding roller 106, under the combined action of the telescopic column 432 and the elastic device 431 inside the fixed frame 41, the flattening plate 42 is driven to move, so that the flattening plate 42 slides inside the fixed groove 434. Under the action of the fixed groove 434, the flattening plate 42 is guided. Under the combined action of the telescopic column 432 and the elastic device 431 inside the fixed frame 41, the bottom of the flattening plate 42 is driven to move into contact with the surface of the woven bag body 103. Under the action of the flattening plate 42, the two sides of the woven bag body 103 are flattened and pressed. When there is more woven bag body 103 wound on the surface of the winding roller 106, at this time, the moving plate 433 is adjusted up and down to the required position on the inner wall of the support plate 102. Under the action of the flattening plate 42, the woven bag body 103 wound on the surface of the winding roller 106 can be pressed and prevented from loosening, so as to realize the function of the winding device to flatten and press the woven bag body 103 on the surface of the winding roller 106, so that the winding device can flatten the woven bag body 103 on the surface of the winding roller 106 during use, so that the woven bag body 103 can be tightened when wound on the surface of the winding roller 106, ensuring the compactness of the winding device when winding the woven bag body 103.
[0034] Subsequently, the user pulls the winding roller 106, causing the winding roller 106 to move away from the rotating column 105. The winding roller 106 slides inside the guiding groove 32, and the guiding groove 32 guides the winding roller 106. At this time, the winding roller 106 drives the anti-detachment clamping member 33 away from the inside of the fixed cylinder 31. At this time, the winding roller 106 drives the first magnet 34 away from the surface of the second magnet 35, thereby pulling out the winding roller 106 and the woven bag body 103 from the inside of the support frame plate 102. Subsequently, the user pulls the winding roller 106, causing the winding roller 106 to slide inside the rotating member 107, and pulling out the winding roller 106 and the woven bag body 103 from the inside of the support frame plate 102, and performing disassembly and assembly on the winding roller 106, so as to realize the function that the winding device can conveniently disassemble and assemble the winding roller 106, so that when the winding device is used, the user can conveniently remove the winding roller 106 from the inside of the support frame plate 102, perform replacement processing on the winding roller 106, making it more convenient and smooth for the user to operate the winding device, with higher working efficiency, and finally completing the use of the winding device.
