Abstract
Description
Technical Field
[0001] This utility model relates to the field of white cardboard production, and more specifically, it relates to a winding device for white cardboard. Background Technology
[0002] White cardboard is very common in people's work and daily life. Compared with ordinary white paper, white cardboard is denser and more uniform in thickness. Its surface is generally whiter and smoother, with more uniform ink absorption, less surface dusting and linting, and is stronger and more durable, making it easier for people to write or make certain products. After the white cardboard is produced, it is usually wound into a roll by a winding device. Current winding devices are generally just paper rolls. After the white cardboard is wound onto the paper roll, it is generally pressed through a plastic... The strip secures the paper roll to prevent it from unraveling. However, when using the paper roll, the strip needs to be cut. Existing winding devices lack a fixing structure. Because white cardboard has a certain degree of toughness, the paper roll can become loose, making it difficult for the winding drum to transport the white cardboard. At the same time, existing winding drums need to be connected to motors and other equipment during the winding process. After the winding drum finishes winding the white cardboard, the connection between the winding drum and the motor is disconnected, and the winding drum is placed on the ground. Pollutants or dust on the ground can contaminate the white cardboard, thus affecting the production quality of the white cardboard. Utility Model Content

[0015] (III) Beneficial Effects
[0016] Compared with the prior art, this utility model provides a winding device for white cardboard, which has the following advantages:
[0017] 1. This utility model, by setting a first fixing structure, when it is necessary to use the white cardboard rolled on the take-up drum, rotates the first threaded rod at the upper end of the connecting frame. Through the rotational connection between the first threaded rod and the first fixing block and the threaded connection between the first threaded rod and the connecting frame, the rotation of the first threaded rod causes the first fixing block to contact the uppermost surface of the white cardboard roll, thereby limiting the white cardboard roll. When the plastic strip is cut, the white cardboard roll is supported by the first fixing block to prevent the white cardboard roll from loosening, thus facilitating the use of the white cardboard roll.
[0018] 2. This utility model, by setting a second fixing structure, uses bolts to connect the fixing holes on the support frame and the fixing holes on the mounting frame to install the second fixing structure on the mounting frame. Based on the thickness of the white cardboard roll, the second fixing block contacts the uppermost surface of the white cardboard roll through the cooperation between the collar and the connecting rod. Bolts are inserted into the limiting holes to fix the position of the second fixing block. The last edge of the white cardboard roll is placed between the pressure plate and the second fixing block. Rotating the second threaded rod, through the threaded connection between the second threaded rod and the fixing frame, moves the pressure plate. The cooperation between the pressure plate and the second fixing block presses the white cardboard roll between them, making it easier to find the unfolded position of the white cardboard roll when using it, thus facilitating its fixing and use.
[0019] 3. This utility model, by setting support legs on the mounting frame, allows the support legs to be rotated so that the lowest end of the support leg contacts the ground after the white cardboard roll is wound up. Bolts are then inserted into the threaded holes to fix the position of the support legs. This supports the entire winding drum, preventing the white cardboard roll from contacting the ground, thus reducing contamination during the winding process and facilitating high-quality production of the white cardboard roll.

[0031] In this embodiment, the main structure of the entire winding device is formed by the winding drum 1 and the mounting frame 3.
[0032] More specifically, the rolled-up white cardboard roll is fixed by the first and second fixing structures to prevent it from becoming loose and to facilitate its use.
[0033] Please see Figures 1-5 As one implementation method to prevent the white cardboard roll from loosening: the mounting frame 3 has a through hole 12, and a connecting block 13 is fixedly installed at the lower end of the connecting frame 4. The connecting block 13 and the through hole 12 cooperate with each other. The first fixing block 5 is movably installed on the connecting frame 4. The first threaded rod 6 and the sliding rod 7 both pass through the connecting frame 4. The connecting block 13 and the mounting frame 3 both have connecting holes 14. The connecting holes 14 are threaded. The first threaded rod 6 is rotatably connected to the first fixing block 5 through a bearing. The sliding rod 7 is fixedly connected to the first fixing block 5. The first threaded rod 6 is threadedly connected to the connecting frame 4. The sliding rod 7 is slidably connected to the connecting frame 4. The connecting hole 14 on the connecting block 13 is bolted to the connecting hole 14 on the mounting frame 3. The mounting frame 3 has a notch. 15. The support frame 8 is detachably installed in the notch 15. A connecting rod 16 is fixedly installed on the second fixing block 9. The connecting rod 16 passes through the support frame 8. The pressure plate 10 is movably installed in the fixing frame 11. Fixing holes 17 are opened on both the mounting frame 3 and the support frame 8. Multiple fixing holes 17 are opened on the mounting frame 3. A collar 18 is fixedly installed on the support frame 8. The collar 18 and the connecting rod 16 cooperate with each other. A second threaded rod 19 is rotatably installed on the upper end of the pressure plate 10. The second threaded rod 19 passes through the fixing frame 11. Limiting holes 20 are opened on both the collar 18 and the connecting rod 16. Threads are provided in the limiting holes 20. Multiple limiting holes 20 are opened on the connecting rod 16. The second threaded rod 19 is threadedly connected to the fixing frame 11.
[0034] Specifically, when winding the white cardboard roll, an external motor is connected to the winding drum 1. The winding drum 1 has a keyway that mates with the motor shaft. After the white cardboard roll is wound, the second fixing structure is installed on the mounting frame 3 by bolting between the fixing holes 17 on the support frame 8 and the fixing holes 17 on the mounting frame 3. Based on the thickness of the white cardboard roll, the second fixing block 9 is brought into contact with the uppermost surface of the white cardboard roll by the engagement between the collar 18 and the connecting rod 16. The bolt is inserted into the limiting hole 20 to fix the position of the second fixing block 9. The last side of the white cardboard roll is placed between the pressure plate 10 and the second fixing block 9, and the second threaded rod is rotated. 19. The pressure plate 10 is moved by the threaded connection between the second threaded rod 19 and the fixed frame 11. The white cardboard roll is pressed between the pressure plate 10 and the second fixed block 9 through the cooperation between the pressure plate 10 and the second fixed block 9. When the white cardboard needs to be used on the winding drum 1, the first threaded rod 6 at the upper end of the connecting frame 4 is rotated. Through the rotational connection between the first threaded rod 6 and the first fixed block 5 and the threaded connection between the first threaded rod 6 and the connecting frame 4, the rotation of the first threaded rod 6 causes the first fixed block 5 to contact the uppermost surface of the white cardboard roll, thereby limiting the white cardboard roll. When the plastic strip is cut, the white cardboard roll is supported by the first fixed block 5 to prevent the white cardboard roll from loosening.
[0035] Please refer to Figure 1-5 As one embodiment of supporting the winding drum 1 after winding is completed: a mounting plate 21 is fixedly provided on the side end of the mounting frame 3, and multiple mounting plates 21 are provided. A support leg 22 is provided between two mounting plates 21. The support leg 22 is rotatably connected to the mounting plate 21. Threaded holes 23 are provided on both the support leg 22 and the mounting plate 21.
[0036] Specifically, after the white cardboard roll is wound up, the support leg 22 is rotated so that the lowest end of the support leg 22 contacts the ground. The bolt is inserted into the threaded hole 23 to fix the position of the support leg 22, thereby supporting the entire winding drum 1 through the support leg 22 and preventing the white cardboard roll from contacting the ground.
[0037] In summary, when using it as a whole:
[0038] When winding the white cardboard roll, an external motor is connected to the winding drum 1. The winding drum 1 has a keyway that mates with the motor shaft. After the white cardboard roll is wound, the second fixing structure is installed on the mounting frame 3 by bolting the fixing holes 17 on the support frame 8 and the mounting frame 3. Based on the thickness of the white cardboard roll, the second fixing block 9 contacts the uppermost surface of the white cardboard roll through the engagement between the collar 18 and the connecting rod 16. The bolt is inserted into the limiting hole 20 to fix the position of the second fixing block 9. The last side of the white cardboard roll is placed between the pressure plate 10 and the second fixing block 9. The second threaded rod 19 is rotated, and the pressure plate 10 is moved through the threaded connection between the second threaded rod 19 and the fixing frame 11. The white cardboard roll is pressed between the pressure plate 10 and the second fixing block 9 through the engagement of the pressure plate 10 and the second fixing block 9, which facilitates the subsequent use of the white cardboard roll.
[0039] After the white cardboard roll is wound up, rotate the support leg 22 so that the bottom of the support leg 22 contacts the ground. Insert the bolt into the threaded hole 23 to fix the position of the support leg 22, thereby supporting the entire winding drum 1 through the support leg 22 and preventing the white cardboard roll from contacting the ground.
[0040] When the white cardboard needs to be wound on the take-up drum 1, rotate the first threaded rod 6 at the upper end of the connecting frame 4. Through the rotational connection between the first threaded rod 6 and the first fixing block 5 and the threaded connection between the first threaded rod 6 and the connecting frame 4, the rotation of the first threaded rod 6 causes the first fixing block 5 to contact the uppermost surface of the white cardboard roll, thereby limiting the white cardboard roll. When the plastic strip is cut, the white cardboard roll is supported by the first fixing block 5 to prevent the white cardboard roll from becoming loose.
[0041] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model 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 utility model. The scope of this utility model is defined by the appended claims and their equivalents.
