[0002] Winding is a method of curling the materials of some continuous products with a reel. During the production process of transfer paper, the just-produced transfer paper needs to be wound on a winding roller. During the winding process of the transfer paper, a paper tube is sleeved on the winding roller first, and then the transfer paper is wound on the paper tube. The number of the wound transfer paper is assisted to be controlled by a baffle, and the paper tube is removed after winding is completed.

[0003] In the prior art device, corresponding mounting platforms are respectively rotatably connected to both sides of the winding roller, fixed rods are fixedly connected to the mounting platforms, and limiting grooves are formed in the near ends of the two fixed rods. Therefore, by fixedly connecting limiting rods to the limiting grooves respectively on both sides of the baffle, the height of the baffle can be controlled by inserting the limiting rods into the limiting grooves.

[0004] However, the above method makes the position of the baffle must match the limiting groove, that is, the position change of the baffle is a point change, and it can only adapt to a specific number of heights, which makes its application range very narrow.

[0005] Therefore, we believe that a transfer paper guiding and winding roller that can realize the linear height of the baffle and has a large application range is needed. Summary of the Invention

Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0024] Please refer to Figures 1-5 , a transfer paper guiding and winding roller, including a roller shaft 1, which is a cylindrical structure with a larger diameter in the middle section than at both ends, and the larger diameter part in the middle section is used to carry the paper.

[0025] Therefore, a limit plate 2 is coaxially arranged at the upper end of the roller shaft 1 of the present device. When the paper is wound around the roller shaft 1 for a certain number of turns and abuts against the limit plate 2, it means that the number of winding turns of the paper meets the expectation.

[0026] It should be noted that generally, a roller is fixedly connected to the lower end of the limit plate 2 through a telescopic rod to ensure that there are no wrinkles in the multiple layers of paper wound around the roller shaft 1.

[0027] Specifically, in order to control the distance between the limit plate 2 and the side end face of the roller shaft 1, positioning plates 20 are fixedly connected to both ends of the limit plate 2 of the present device. At the same time, driving rings 11 are rotatably connected to both axial ends of the roller shaft 1, and driving grooves 4 are formed through the driving rings 11.

[0028] At this time, driven rods 18 are fixedly connected to the far ends of the two positioning plates 20 respectively by constraints, and the driven rods 18 are inserted into the driving grooves 4. By virtue of the unequal distances between the two ends of the driving groove 4 and the central axis of the driving ring 11, and the characteristic of the smooth transition of the inner wall of the driving groove 4, on the premise that the driven rod 18 can only move in a straight line up and down, by rotating the driving ring 11, the distance between the driven rod 18 and the central axis of the roller shaft 1 can be changed, so as to realize the change of the height of the limiting plate 2. Compared with the prior art device, there is no constraint on the height change range of the limiting plate 2 in this device. The height change range of the limiting plate 2 is linearly and continuously changed, rather than electrically and stagewise changed.

[0029] Specifically, in order to constrain the movement trajectory of the driven rod 18 and ensure that the driven rod 18 can only move in a straight line up and down, a limiting ring 12 is rotatably connected to the roller shaft 1 in this device. And a positioning groove 19 is formed through the limiting ring 12. Then, by constraining the central axis of the positioning groove 19 to coincide with the radius line of the limiting ring 12, when the driven rod 18 is inserted into the positioning groove 19, it can only move in a straight line up and down.

[0030] It should be noted that in practice, this device does not exist in isolation. It necessarily requires a certain bearing medium, for example, a workbench. Therefore, in order to ensure the constraint effect of the positioning groove 19 on the driven rod 18, a fixing bolt I 3 is provided on one side of the limiting ring 12 in this device for connecting with the workbench, so as to ensure that the limiting ring 12 can remain stationary relative to the workbench in practice.

[0031] Furthermore, in order to avoid the reduction of the service life of the device caused by frictional loss, a sleeve 17 is sleeved outside the driven rod 18 in this device, and the sleeve 17 is constrained to be rotatably connected to the driven rod 18. Then, when the sleeve 17 is inserted into the positioning groove 19 and the driving groove 4, the relative movement between the sleeve 17 and the limiting ring 12 and the driving ring 11 can be used to reduce the frictional resistance.

[0032] Furthermore, in order to constrain the position of the sleeve 17 and ensure that it is always inserted into the positioning groove 19 and the driving groove 4, external threads are provided on the outside of the driven rod 18, and two limiting nuts 16 are screwed along the central axis direction through the external threads. At this time, the sleeve 17 is constrained to be located between the two limiting nuts 16, so that the relative movement between the sleeve 17 and the driven rod 18 can be ensured not to occur. At the same time, as shown in the figure, the far ends of the two positioning plates 20 are respectively abutted against the two driving rings 11, so that the positioning rod cannot move left and right relative to the driving ring 11 either. At this time, by virtue of the fixed connection between the driven rod 18 and the positioning rod, it can be ensured that the sleeve 17 is always inserted into the driving groove 4 and the positioning groove 19.

[0033] Furthermore, in order to avoid the situation where the restraining effect of the positioning groove 19 on the driven rod 18 and the pushing effect of the driving groove 4 on the driven rod 18 are not in the same vertical plane, causing the driven rod 18 to receive additional torsional force, the device is respectively provided with a driving ring 11 on the left and right sides of each limiting ring 12. By providing two driving rings 11, and the two driving rings 11 are located on both sides of the limiting ring 12, it is ensured that the force of each driven rod 18 is balanced.

[0034] Therefore, in order to ensure the synchronous rotation of the two drive rings 11 on one side, the device has a follower gear 10 coaxially fixedly connected to the outside of each drive ring 11, and one side of the follower gear 10 is meshingly connected to a driven gear 9. At this time, it is only necessary to ensure the synchronous rotation of the two driven gears 9 on one side to achieve the synchronous rotation of the two drive rings 11 on the same side.

[0035] Therefore, the device is provided with a transmission rod 14 between the two driven gears 9 on one side, and the transmission rod 14 is constrained to be coaxially fixed with the corresponding two driven gears 9, so that the two driven gears 9 on one side can rotate synchronously.

[0036] Furthermore, in the present device, a transmission gear 13 is coaxially fixedly connected to the middle section of the driven rod 18, and a driving gear 8 is meshingly connected to one side of the transmission gear 13. By adjusting the transmission ratio between different gears, the driving gear 8 can only drive the follower gear 10 to rotate slightly during rotation. This can fully ensure the rotation accuracy of the follower gear 10, that is, the rotation accuracy of the limit ring 12 meets actual needs.

[0037] Specifically, in order to ensure that the two driving gears 8 on both sides rotate synchronously and avoid the limit plate 2 from tilting, the device is provided with a driving motor 5 on one side of each driving gear 8, and the output shaft of the driving gear 8 is constrained to be meshed and connected with the corresponding driving gear 8. It is only necessary to ensure that the two driving motors 5 move at the same frequency to achieve the expected goal.

[0038] Specifically, in order to constrain the position of the transmission rod 14, that is, the position of the transmission gear 13 and the driven gear 9, and ensure that they are in a correct meshing state, the device is provided with a fixing ring 15 on the outside of the transmission rod 14, and the fixing ring 15 is constrained to be rotatably connected with the limiting ring 12, so that the position of the transmission rod 14 can be fixed by using the limiting ring 12.

[0039] Specifically, as shown above, the device can limit the position of the drive motor 5 and the drive gear 8 by fixing the mounting plate 7 at the lower end of the drive motor 5, and then providing a fixing bolt II 6 on the mounting plate 7 for connecting with the workbench.

[0040] In actual use, the utility model:

[0041] First, the interference fit is used to combine the bearing to achieve the fixed connection between the limit ring 12 and the transmission gear 13, the driven gear 9, and the transmission rod 14;

[0042] Then, the driving ring 11 and the limit ring 12 are successively installed in place at both ends of the roller shaft 1 by using the bearing;

[0043] After that, the sleeve 17 is inserted into the corresponding driving groove 4. At the same time, the driven rod 18 is connected to the positioning plate 20 and the sleeve 17 to complete the connection;

[0044] Finally, the device starts to work normally. By turning on the driving motor 5, the driving ring 11 is controlled to rotate, and the relative distance between the limit plate 2 and the roller shaft 1 is changed to realize the limitation of the number of turns of the wound paper.

[0045] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
