[0026] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are 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 cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0028] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0029] like Figure 1 and Figure 2 As shown, it includes a support component 1 and a speed regulating component 2, the speed regulating component 2 is arranged on the support component 1, the material roll 3 is rotatably mounted on the support component 1, the support component 1 includes a support plate 11 for supporting and a support rod 12 for hanging the material roll 3, the support rod 12 is arranged on the support plate 11, the support rod 12 is used to mount the material roll 3, the material roll 3 is rotatably suspended on the support rod 12, the material roll 3 rotates on the support rod 12, and the material belt 4 is released.

[0030] The speed regulating assembly 2 includes a fixed plate 21, an elastic member 22 and a movable plate 23. The fixed plate 21 is arranged on the support plate 11, and the movable plate 23 is rotatably arranged on the support plate 11. The two ends of the elastic member 22 are respectively connected to the fixed plate 21 and the movable plate 23. The speed regulating assembly 2 also includes a guide shaft 24. The two ends of the movable plate 23 are respectively connected to the guide shaft 24 and the elastic member 22. The released material belt 4 is wound around the guide shaft 24, and the material belt 4 passes through the guide shaft 24 to the next process.

[0031] When the material belt 4 moves, it exerts a force on the guide shaft 24, and the movable plate 23 rotates to a set angle. At this time, the elastic member 22 is stretched, and the material roll 3 accelerates its rotation under the action of the traction force of the material belt 4. When the material belt 4 at the front end is processed, the material belt 4 stops moving, and the force of the material belt 4 on the guide shaft 24 is reduced. The guide shaft 24 and the movable plate 23 are reset by rotation. Under the action of inertia, the elastic member 22 is slightly compressed. At this time, there is no traction force on the material roll 3, and the material roll 3 slows down its rotation, releasing a small amount of the material belt 4, thereby releasing an appropriate amount of the material roll 3.

[0032] When the material belt 4 in front moves, the material roll 3 has released part of the material belt 4. Then, when the material belt 4 starts to move, the rolling friction between the material belt 4 and the guide shaft 24 is small. As the material belt 4 moves, the rolling friction between the material belt 4 and the guide shaft 24 becomes larger and larger, until the material belt 4 presses the guide shaft 24 downward to realize the above cycle.

[0033] The guide shaft 24 and the support rod 12 are arranged in parallel with each other at a distance. There is enough space between the guide shaft 24 and the support rod 12. The material roll 3 releases the material belt 4. The guide shaft 24 is used for winding the material belt 4. The material belt 4 is half wound on the guide shaft 24.

[0034] The elastic member 22 has two states: stretched and compressed. The elastic member 22 is a spring.

[0035] The support assembly 1 also includes a vertical plate 13, which is rotatably arranged at the bottom end of the support plate 11. The support plate 11 is supported by other equipment. The support plate 11 is tiltedly arranged on the vertical plate 13. The vertical plate 13 can rotate on the support plate 11. The vertical plate 13 and the support plate 11 are rotatably connected by bolts.

[0036] A limiting hole 14 with an arc is set on the top of the vertical plate 13, and a fixing hole 15 is set at the bottom of the support plate 11. The fixing hole 15 is connected to the limiting hole 14 by screws. After the vertical plate 13 is rotated to a set angle, the screws are inserted into the limiting hole 14 and the fixing hole 15 to keep the position of the vertical plate 13 unchanged after rotation.

[0037] A positioning rod 16 is also provided at the bottom of the support plate 11, and a positioning disk 17 is provided at the extended end of the positioning rod 16. A limiting groove 18 is provided at the top of the vertical plate 13, and the positioning rod 16 is located on the rotation path of the limiting groove 18. When the support plate 11 is fixed to other equipment, the positioning rod 16 and the positioning disk 17 are used for fixing. When the vertical plate 13 is to be rotated, the positioning rod 16 is close to the top of the vertical plate 13, and the vertical plate 13 cannot be rotated to any angle, so the support plate 11 is used to block the limiting groove 18 so that the top of the vertical plate 13 can no longer rotate.

[0038] A bottom rod 19 is provided at the bottom of the vertical plate 13, and the position of the bottom rod 19 is lower than the position of the guide shaft 24. The material belt 4 passes through the guide shaft 24, and then the material belt 4 is half-wound on the bottom rod 19. When the material belt 4 is wound on the bottom rod 19, it can be wetted. The bottom rod 19 and the vertical plate 13 can be set in a liquid pool.

[0039] A first auxiliary rod 31 is also provided on the support plate 11. The first auxiliary rod 31 is located between the guide shaft 24 and the support rod 12, and the position of the first auxiliary rod 31 is lower than the positions of the guide shaft 24 and the support rod 12. The material strip 4 is wound downwardly around the first auxiliary rod 31, and then the material strip 4 is wound upwardly around the guide shaft 24. The material strip 4 can reduce its hardness by being wound downwardly and upwardly.

[0040] The support plate 11 is also provided with a second auxiliary rod 32 and a third auxiliary rod 33. The second auxiliary rod 32 is located between the third auxiliary rod 33 and the first auxiliary rod 31, and the third auxiliary rod 33 is located between the second auxiliary rod 32 and the bottom rod 19. The position of the second auxiliary rod 32 is lower than that of the first auxiliary rod 31, and the position of the third auxiliary rod 33 is lower than that of the second auxiliary rod 32. After the material belt 4 flows out from the guide shaft 24, it is respectively wrapped around the second auxiliary rod 32 and the third auxiliary rod 33, and finally wrapped around the bottom rod 19.

[0041] The movable plate 23 is rotatably disposed on the support plate 11 at a central position, thereby ensuring that the forces on both ends of the movable plate 23 are uniform.

[0042] Guide wheels 20 are mounted on the bottom rod 19, the guide shaft 24, the first auxiliary rod 31, the second auxiliary rod 32 and the third auxiliary rod 33. When there are more than two material rolls 3 on the support rod 12, the guide wheel 20 is located between two adjacent material strips 4. At the same time, the guide wheel 20 also prevents the material strip 4 from shifting when moving. The position of the guide wheel 20 is set according to the width of the material strip 4.

They cannot be used to limit the protection scope of the utility model. All equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
