Technical Field

[0001] The utility model relates to the field of toilet paper winding, in particular to a toilet paper winding machine with adjustable tension. Background Art

[0002] The toilet paper wrapping machine is a special packaging machine, mainly used for the automated wrapping and packaging process of toilet paper. It can wrap flexible packaging materials partially or completely on the supporting structure to achieve the packaging requirements of containerized storage, transportation and mechanized loading and unloading operations of the product. The toilet paper wrapping machine is widely used in the toilet paper production and packaging industry and is one of the indispensable equipment in the modern packaging process.

[0003] A Chinese patent with publication number CN219278982U discloses a thickened toilet paper rolling device, including a movable plate. Connecting blocks with one end extending to the bottom of the L-shaped plate are provided on both the left and right sides of the bottom of the movable plate. A downward pressure assembly is provided at the bottom of the left connecting block, with one end fixedly connected to the bottom of the right connecting block. The threaded rod is driven to rotate by starting the servo motor, and the threaded rod drives the movable plate, the connecting block and the downward pressure assembly as a whole to adjust the distance between the pressure roller and the supporting roller, so that thickened toilet paper of different thicknesses can be guided, thereby improving the practicality of the equipment.

[0004] The toilet paper rolling device of the above patent only adapts the thickness of the paper during the rolling process, and does not tighten the paper during the rolling process. The tensioning force is low, which can easily cause slippage during the rolling process. It can also easily cause the tightness between the papers to decrease during the rolling process, affecting subsequent storage and use. Summary of the Invention

[0005] The purpose of the utility model is to provide a toilet paper winding machine with adjustable tensioning force. After the toilet paper wrapped around the outside of the winding column continuously squeezes the second pressing roller, the second pressing roller will move longitudinally upward. During the longitudinal movement, the second transmission plate will be driven to move laterally through the meshing connection and the transmission of the synchronous belt. The lateral movement of the second transmission plate will pull the tensioning roller used for tensioning, and synchronously adjust the position of the tensioning roller, thereby solving the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a toilet paper winding machine with adjustable tensioning force, comprising a winding column, a support roller is provided on one side of the winding column, a second pressing roller is provided on the upper end of the winding column, a tensioning roller is provided between the winding column and the support roller, a fixed plate is provided at one end of the second pressing roller, a first transmission plate is provided at the rear end of the fixed plate, a second transmission plate is provided at the lower end of one side of the first transmission plate, and a tooth groove is welded on one side of the first transmission plate and the upper end of the second transmission plate.

[0007] Preferably, a first gear meshing with the tooth groove is provided on the upper end of one side of the first transmission plate, and a third gear meshing with the tooth groove is provided on one side of the upper end of the second transmission plate.

A third sliding rail is provided inside the fixed plate at one end close to the tensioning roller, and the tensioning roller passes through the third sliding rail and extends to the front and rear ends of the fixed plate.

[0010] Preferably, one end of the second pressing roller is clamped into the interior of the first transmission plate and is rotatably connected to the interior of the first transmission plate, and one end of the tensioning roller is clamped into the interior of the second transmission plate and is rotatably connected to the interior of the second transmission plate.

[0011] Preferably, the interior of the first transmission plate and the second transmission plate are both recessed with second sliding rails, and a limiting frame is provided on one side of the exterior of the two second sliding rails, and one end of the limiting frame is embedded in the interior of the second sliding rail and slidably connected to the interior of the second sliding rail.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1. In the present invention, the more toilet paper is wound around the outside of the winding column in a rotating state, the more the paper will gradually squeeze the upper end to press and contact the second pressing roller of the toilet paper. The second pressing roller slides longitudinally in the first sliding rail, which will drive the first transmission plate to slide longitudinally. The first transmission plate drives the first gear to rotate through the tooth groove. The rotation of the first gear is adjusted by the second gear and then driven by the synchronous belt to rotate the third gear. The rotation of the third gear can drive the second transmission plate to slide horizontally through the tooth groove. The sliding of the second transmission plate will drive the tensioning roller to continuously move away from the winding column. The tensioning roller is located on one side of the winding column and is matched with the second pressing roller to press the upper end of the toilet paper, so that the toilet paper can be stably wound around the outside of the winding column. The tensioning force provided by the tensioning roller and the second pressing roller can reduce the gap between the wound toilet papers. Moreover, as the paper restricts the second pressing roller, the lateral tensioning position of the tensioning roller can be adjusted synchronously and continuously adjusted during the winding process.

DETAILED DESCRIPTION

[0022] The present invention will be further described below with reference to specific embodiments.

[0023] Example 1

[0024] like Figure 1As shown, a toilet paper winding machine with adjustable tension in this embodiment includes a winding column 4, one end of which is provided with a motor 8, and the output shaft of the motor 8 is rotatably connected to one end of the winding column 4, and one side of the winding column 4 is provided with a support roller 3 for holding up the toilet paper, the upper end of the support roller 3 is provided with a first pressing roller 2, and the upper end of the first pressing roller 2 is provided with a hydraulic telescopic rod, through the extension and contraction of the first pressing roller 2, the first pressing roller 2 can be pushed to continuously move toward the support roller 3, and the first pressing roller 2 and the support roller 3 can clamp the paper to improve the stability of the toilet paper during winding;

[0025] Among them, Figure 1 and Figure 3 As shown, in order to increase the tension of the toilet paper during winding, a second pressing roller 5 is provided at the upper end of the winding column 4. The second pressing roller 5 falls due to its own weight and continuously presses the toilet paper wrapped around the outside of the winding column 4. A tensioning roller 18 is provided between the winding column 4 and the supporting roller 3. The tensioning roller 18 tightens the toilet paper in the transmission process by the pressure of the second pressing roller 5, and actively makes the toilet paper close to the winding column 4 and the toilet paper wrapped around the outside of the winding column 4, thereby increasing friction and avoiding slipping during winding. At the same time, the winding effect can be improved by increasing the tension, thereby avoiding gaps inside the toilet paper after winding and avoiding slipping during winding.

[0026] In addition, in order to make the second pressing roller 5 and the tensioning roller 18 adapt to the amount of toilet paper continuously wound, a fixed plate 1 is provided at one end of the second pressing roller 5, and a first sliding rail 7 is provided inside the fixed plate 1. The second pressing roller 5 passes through the first sliding rail 7 and extends to the front and rear ends of the fixed plate 1. As the toilet paper outside the winding column 4 is continuously wound, the toilet paper will squeeze the second pressing roller 5, and the second pressing roller 5 will slide longitudinally upward along the first sliding rail 7;

[0027] like Figure 3 As shown, a third sliding rail 17 is provided at one end of the fixed plate 1 near the tensioning roller 18, and the tensioning roller 18 passes through the third sliding rail 17 and extends to the front and rear ends of the fixed plate 1. When the second pressing roller 5 is adjusted in position, the tensioning roller 18 is driven by the transmission to move and adjust laterally along the third sliding rail 17, thereby adjusting the tensioning force and adapting to the amount of wound toilet paper.

[0028] The rear end of the fixed plate 1 is provided with a first transmission piece 9, and the lower end of one side of the first transmission piece 9 is provided with a second transmission piece 10. Figure 2 and Figure 4As shown, one end of the second pressing roller 5 is inserted into the first transmission piece 9 and is connected to the internal rotation of the first transmission piece 9, and one end of the tensioning roller 18 is inserted into the second transmission piece 10 and is connected to the internal rotation of the second transmission piece 10. The second pressing roller 5 drives the first transmission piece 9 to move longitudinally during the longitudinal movement after being squeezed, and pulls the second transmission piece 10 to move laterally after the transmission of the first transmission piece 9. The lateral movement of the second transmission piece 10 drives the tensioning roller 18 to adjust its lateral position.

[0029] Among them, one side of the first transmission plate 9 and the upper end of the second transmission plate 10 are both provided with a tooth groove 12, and the tooth groove 12 is respectively welded and fixed to the corresponding one side of the first transmission plate 9 and the upper end of the second transmission plate 10, the upper end of one side of the first transmission plate 9 is provided with a first gear 11, and one side of the upper end of the second transmission plate 10 is provided with a third gear 14, and the outer sides of the third gear 14 and the first gear 11 are respectively meshed with the tooth groove 12. Through the meshing connection, the first transmission plate 9 and the second transmission plate 10 can respectively drive the first gear 11 and the third gear 14 to rotate when they move laterally;

[0030] like Figure 4 As shown, a second gear 13 is meshed with one side of the outside of the first gear 11, and the second gear 13 and the third gear 14 are connected by a synchronous belt transmission. Through the meshing connection and the transmission connection of the synchronous belt, the first transmission plate 9 can move longitudinally while driving the second transmission plate 10 to move laterally; Example 2

[0031] In order to improve the stability of the first transmission plate 9 and the second transmission plate 10 during the lateral movement, the first transmission plate 9 and the second transmission plate 10 are both recessed with a second sliding rail 15, such as Figure 2 and Figure 5 As shown, a limiting frame 16 is provided on one side of the exterior of each of the two second sliding rails 15, and one end of the limiting frame 16 is embedded in the interior of the second sliding rail 15 and is slidably connected to the interior of the second sliding rail 15, and the other end of the limiting frame 16 is fixedly connected to the fixed plate 1 by a bolt. By embedding the limiting frame 16 in the interior of the first transmission plate 9 and the second transmission plate 10, the stability of the first transmission plate 9 and the second transmission plate 10 when sliding horizontally can be improved; Example 3

[0032] A fixing disk 6 is provided at the front end of the outside of the winding column 4, and the end of the fixing disk 6 facing the winding column 4 is matched with the internal thread of the winding column 4. The rotation of the fixing disk 6 can be fixed to the front end of the outside of the winding column 4. After the fixing disk 6 is removed by rotating, the toilet paper wrapped around the outside of the winding column 4 can be removed.

[0033] Working principle: When the device is used and toilet paper is wound, the toilet paper passes between the first pressing roller 2 and the supporting roller 3, and one end of the toilet paper is fixed on the surface of the winding column 4. The hydraulic structure at the upper end of the first pressing roller 2 is started. The extension and contraction of the hydraulic structure can push the first pressing roller 2, so that the first pressing roller 2 and the supporting roller 3 can clamp the paper while adapting to the thickness of the paper. The motor 8 is started to output the winding column 4. The rotation of the winding column 4 can realize the winding of the connected toilet paper. After being tensioned by the tensioning roller 18, the paper can be pressed by the second pressing roller 5 and can be wound around the outside of the winding column 4 layer by layer. With the continuous rotation of the winding column 4 and the gradual increase of external toilet paper, the second pressing roller 5 slides longitudinally along the first sliding rail 7 due to the squeezing of the winding paper. While the first sliding rail 7 slides, it drives the tooth groove 12 to contact the first gear 11. The first gear 11 rotates after contact. The rotation of the first gear 11 can drive the second gear 13 to rotate. The second gear 13 drives the rotation of the third gear 14 through the transmission of the synchronous belt. The rotation of the third gear 14 can drive the second transmission plate 10 to move horizontally through the tooth groove 12. The lateral movement of the second transmission plate 10 can drive the tensioning roller 18 for tensioning.
