[0002] The collecting winding drum roll shaft is a mechanical equipment component used in industries such as papermaking, printing, and packaging. It is mainly used to collect and support the winding drums of paper, film, or other materials, ensuring that the materials can be smoothly and evenly transported and processed during the production process.

[0003] During the use of the existing collecting winding drum roll shaft, although it can wind items, it cannot quickly replace the collecting winding drum roll shaft, resulting in a large amount of time required for disassembling the collecting winding drum roll shaft. At the same time, the roll shaft cannot be fixed during use, resulting in the situation that the roll shaft will fall during operation. Therefore, a roll shaft structure of a collecting winding drum with quick replacement is introduced. Content of the Utility Model

[0011] Compared with the prior art, the present utility model has the following beneficial effects:

[0012] 1. For the rapid replacement collecting reel roller shaft structure, when the roller shaft body is placed into the inner walls of the limiting rod and the rotating rod, the roller shaft body presses the clamping block. After the clamping block is pressed, it moves backward, so that the clamping block presses the third spring and the pressing rod at the same time. After the pressing rod is pressed, it rotates in the inner wall of the moving block and presses the moving block, so that the moving block moves on the outer wall of the fixing rod under the pressure, and the moving block presses the fourth spring when moving. At the same time, the elastic potential energies of the third spring and the fourth spring are released simultaneously, so that the clamping block clamps the outer wall of the roller shaft body, thereby realizing the fixation of the roller shaft body.

[0013] 2. For the rapid replacement collecting reel roller shaft structure, when replacing the roller shaft body, the staff pulls the moving rod upward to move the moving rod, the placing plate and the placing block. At the same time, when the moving rod moves, it will drive the clamping block to lift, so that the clamping block moves out of the inner wall of the limiting shell. When the clamping block moves out of the inner wall of the limiting shell, the limit between the limiting rod and the rotating block is cancelled. By slowly releasing the hand of the staff, the elastic potential energies of the first spring and the second spring are released simultaneously. The first spring and the second spring drive the moving rod to slide in the inner wall of the fixing plate to cancel the limit on the rotating block. By rotating the rotating block by the staff, the rotating block drives the rotating column to rotate in the inner wall of the fixing block, thereby realizing the convenient replacement of the roller shaft body.

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figure 1 - Figure 7A quick-change collection reel roller structure includes a placement rack 1, an outer wall of the placement rack 1 is fixedly equipped with a motor 2, a power output shaft of the motor 2 is fixedly equipped with a rotating rod 3, a top of the placement rack 1 is fixedly equipped with a limit rod 4, a top of the limit rod 4 is fixedly equipped with a fixed block 6, an inner wall of the fixed block 6 is rotatably connected with a rotating column 9, an outer wall of the rotating column 9 is fixedly equipped with a rotating block 10, an inner wall of the rotating block 10 is provided with a limit groove 19, an inner wall of the limit groove 19 is provided with a fixing component 8, and an inner wall of the placement rack 1 is provided with a roller body 5.

[0025] In the above structure, the power output shaft of the motor 2 drives the rotating rod 3 when it rotates, so that the rotating rod 3 drives the roller body 5 to rotate when it rotates, and then the limiting rod 4 is used to support and limit the roller body 5, and the fixing component 8 is used to clamp and fix the roller body 5 so that the roller body 5 will not fall during operation.

[0026] In a preferred embodiment: the outer wall of the limiting rod 4 is fixedly equipped with a fixing plate 7, the inner wall of the fixing plate 7 is fixedly equipped with one end of a spring 12, the other end of the spring 12 is fixedly equipped with a moving rod 13, the outer wall of the moving rod 13 is sleeved with a spring 2 14, the end of the moving rod 13 away from the spring 12 is fixedly equipped with a placing plate 15, the top of the placing plate 15 is fixedly equipped with a placing block 16, the inner wall of the placing block 16 is rotatably connected with a rotating shaft 17, the outer wall of the rotating shaft 17 is fixedly equipped with a clamping block 18, and the outer wall of the rotating block 10 is fixedly equipped with a limiting shell 11.

[0027] In the above structure, during the process of replacing the roller body 5, the staff pulls the moving rod 13 to prompt it to move upward, and this action in turn drives the placement plate 15 and the placement block 16 to move accordingly. At the same time, during the movement of the moving rod 13, it will push the clamping block 18 to lift up, so that the clamping block 18 component is moved out of the inner wall of the limiting shell 11. When the clamping block 18 component is moved out of the inner wall of the limiting shell 11, the limit between the limit rod 4 and the rotating block 10 component is cancelled. Then, the staff slowly releases the hand force, so that the elastic potential energy of spring 12 and spring 2 14 is released. The potential energy release of these components drives the moving rod 13 to slide in the inner wall of the fixed plate 7, thereby canceling the limit on the rotating block 10 component. Finally, the staff rotates the rotating block 10, so that it drives the rotating column 9 to rotate in the inner wall of the fixed block 6, so as to facilitate the smooth replacement of the roller body 5.

[0028] In a preferred embodiment: The fixing component 8 includes a limiting block 801. A fixing rod 802 is fixedly assembled on the inner wall of the limiting block 801. A moving block 803 is slidably connected to the outer wall of the fixing rod 802. One end of a pressure-receiving rod 804 is rotatably connected to the inner wall of the moving block 803. A clamping block 806 is fixedly assembled at the other end of the pressure-receiving rod 804. A fourth spring 807 is fixedly assembled on the outer wall of the moving block 803. A third spring 805 is fixedly assembled on the outer wall of the clamping block 806.

[0029] In the above structure, when the roller body 5 is placed between the inner walls of the limiting rod 4 and the rotating rod 3, the roller body 5 will apply a pressure to the clamping block 806. Affected by this pressure, the clamping block 806 will move backward and apply a pressure to the third spring 805 and the pressure-receiving rod 804. Subsequently, the pressure-receiving rod 804 rotates on the inner wall of the moving block 803 and applies a pressure to the moving block 803. After being pressured, the moving block 803 will move on the outer wall of the fixing rod 802 and apply a pressure to the fourth spring 807 during the movement. At the same time, the elastic potential energy of the third spring 805 and the fourth spring 807 is released, enabling the clamping block 806 to clamp the outer wall of the roller body 5, thereby realizing the fixation of the roller body 5.

[0030] In a preferred embodiment: The fourth spring 807 is fixedly assembled with the outer wall of the limiting block 801. Both the limiting block 801 and the third spring 805 are fixedly assembled with the inner wall of the limiting groove 19.

[0031] In the above structure, the limiting block 801 is used to limit the fourth spring 807 so that the fourth spring 807 will not fall off when releasing the elastic potential energy. The fixing component 8 is limited by the limiting groove 19.

[0032] In a preferred embodiment: The second spring 14 is respectively fixedly assembled with the moving rod 13 and the fixing plate 7. The clamping block 18 is clamped with the inner wall of the limiting shell 11. The moving rod 13 is slidably connected to the inner wall of the fixing plate 7.

[0033] In the above structure, the fixing plate 7 is used to limit the moving rod 13 and the second spring 14 so that the moving rod 13 will not fall off from the inner wall of the fixing plate 7 during movement. The limiting rod 4 and the rotating block 10 are connected and fixed by the clamping of the clamping block 18 and the limiting shell 11.

[0034] In a preferred embodiment: The number of the fixing components 8 is two groups, and the two groups of fixing components 8 are respectively located on the inner walls of the rotating rod 3 and the limiting groove 19.

[0035] In the above structure, the two groups of fixing components 8 are used to fix both ends of the roller body 5, avoiding the situation of falling during the operation.

[0036] Working principle: During the process of replacing the roller body 5, the staff first pulls the moving rod 13 to move it upward. This action drives the placement plate 15 and the placement block 16 to move accordingly. At the same time, the moving rod 13 will push the clamping block 18 to rise during the movement, causing the clamping block 18 to move out of the inner wall of the limit shell 11. When the clamping block 18 leaves the inner wall of the limit shell 11, it will release the limiting mechanism between the limiting rod 4 and the rotating block 10. Subsequently, the staff slowly releases the hand force, enabling the elastic potential energy of the first spring 12 and the second spring 14 to be released. The elasticity of these springs pushes the moving rod 13 to slide on the inner wall of the fixed plate 7, thereby canceling the limit on the rotating block 10. Then, the staff rotates the rotating block 10, which drives the rotating column 9 to rotate on the inner wall of the fixed block 6, facilitating the replacement of the roller body 5. When the roller body 5 is placed into the inner walls of the limiting rod 4 and the rotating rod 3, the roller body 5 will exert pressure on the clamping block 806. After being pressured, the clamping block 806 moves backward and sequentially exerts pressure on the third spring 805 and the pressure-receiving rod 804. After being pressured, the pressure-receiving rod 804 will rotate on the inner wall of the moving block 803 and exert pressure on the moving block 803. During the movement of the moving block 803, it will exert pressure on the outer wall of the fixed rod 802 and simultaneously exert pressure on the fourth spring 807. Finally, the elastic potential energy of the third spring 805 and the fourth spring 807 is released simultaneously, enabling the clamping block 806 to clamp the outer wall of the roller body 5, thus achieving the fixation of the roller body 5.
