[0028] Embodiment:

[0029] An embodiment of the present application discloses a non-adjustable winding belt tensioning wheel. Please refer to Figure 1 、 Figure 2 and Figure 3 , which includes a front plate 1. A rear plate 2 is provided on the rear side of the front plate 1. On both sides between the rear plate 2 and the front plate 1, a first tensioning wheel 3 and a second tensioning wheel 4 are respectively arranged. The first tensioning wheel 3 and the second tensioning wheel 4 are arranged in a meshing manner close to each other. A shaft rod 5 is passed through the inner cavity of the first tensioning wheel 3. The shaft rod 5 is fixedly installed on one end face of the rear plate 2. And bearings 6 are sleeved on the outer walls on both sides of the shaft rod 5. The two bearings 6 are respectively embedded and sleeved at the front and rear ends of the first tensioning wheel 3. One side edge of the rear bearing 6 is provided with a friction disc 7. The friction disc 7 is located outside the rear end of the shaft rod 5. And the friction disc 7 is fixedly installed on one end face of the rear plate 2. One side edge of the front bearing 6 is provided with a limiting disc 9. The limiting disc 9 contacts the front end face of the shaft rod 5. And a first slot 10 is slidably clamped on the outer wall of the limiting disc 9. The first slot 10 is opened in the inner cavity on one side of the front plate 1. A plurality of disc springs 8 are stacked between the limiting disc 9 and the front bearing 6. And the plurality of disc springs 8 are all movably sleeved on the outer wall of the front end of the shaft rod 5. A square groove 12 is opened at the center position of one end of the shaft rod 5 facing the limiting disc 9. A square rod 11 is slidably clamped on the inner wall of the square groove 12. And the square rod 11 is fixedly installed at the center of one end face of the limiting disc 9. A positioning structure is arranged in the inner cavity of the second tensioning wheel 4. A locking structure is arranged at the front end position of the limiting disc 9;

[0030] The locking structure includes a movable blocking strip 13 that slidably contacts the front end face of the limiting disc 9. Metal sliding rods 14 are slidably sleeved through the inner cavities at the upper and lower ends of the movable blocking strip 13. The two metal sliding rods 14 are both in a "U"-shaped rod structure. And the two metal sliding rods 14 are both fixedly installed on the front end face of the front plate 1. A first magnetic sheet 15 is embedded and fixedly installed at the center position of the movable blocking strip 13;

[0031] The locking structure further includes an extension strip 16 that contacts one end face of the movable stop strip 13. The extension strip 16 is fixedly installed on the front end face of the limit disk 9, and a second magnetic sheet 17 is fixedly installed in an embedded manner at the central position of the extension strip 16. Both the first magnetic sheet 15 and the second magnetic sheet 17 are made of magnet body materials, and the opposite end faces of the first magnetic sheet 15 and the second magnetic sheet 17 are in butt joint magnetic adsorption adaptation. Among them, with the setting of the extension strip 16, while being able to accommodate the second magnetic sheet 17 in an embedded manner, it can also realize the limiting abutting effect on the acting position on one side of the movable stop strip 13. Moreover, in the state of the fixed connection between the extension strip 16 and the front end of the limit disk 9, it can also realize the handle function for the disassembly and assembly operation of the limit disk 9.

[0032] Please refer to Figure 1 , Figure 2 and Figure 3 , the positioning structure includes a second shaft rod 18 passing through the inner cavity of the second tensioning wheel 4. Bearing bushes 19 are sleeved on the outer walls on both sides of the second shaft rod 18, and the two bearing bushes 19 are respectively sleeved in an embedded manner at the front and rear end positions of the second tensioning wheel 4. The positioning structure further includes a side disk 20 fixedly connected to the front end face of the second shaft rod 18. A second card slot 21 is movably clamped on the outer wall of the side disk 20, and the second card slot 21 is opened in the inner cavity on the other side of the front plate 1;

[0033] Four connecting plates 22 are fixedly connected together on the periphery between the front plate 1 and the rear plate 2. The four connecting plates 22 are distributed in a "cross" shape, and the upper and lower two connecting plates 22 are vertically staggered with respect to the positions between the first tensioning wheel 3 and the second tensioning wheel 4.

[0034] The implementation principle of this embodiment is as follows: During use, when the whole is in a complete assembled state, it can be fixedly assembled at the required working position in the winding and wrapping mechanical equipment. When acting on the winding belt, it is necessary to make the winding belt pass through the position between the first tensioning wheel 3 and the second tensioning wheel 4. When the winding belt is pulled, it indirectly drives the first tensioning wheel 3 and the second tensioning wheel 4 to perform a relative rotational movement.

[0035] When it is necessary to adjust the tension of the winding tape, first horizontally move the movable stop bar 13 so that it linearly moves on the outer walls of the two metal sliding rods 14. At this time, the first magnetic sheet 15 is separated from the second magnetic sheet 17. Until the front end of the limit disk 9 loses its restrictive effect, the limit disk 9 can be extracted from the inside of the first card slot 10, and the square rod 11 is separated from the square groove 12. After that, while installing a butterfly gasket 8 on the front outer wall of the first shaft 5, the original multiple butterfly gaskets 8 are simultaneously pushed backward. At this time, the front bearing 6 is stressed and holds the inner cavity position of the first tensioning wheel 3, so as to hold the rear bearing 6, thereby increasing the frictional contact resistance with the friction disk 7. After that, when the limit disk 9 and the square rod 11 are reset, the movable stop bar 13 is horizontally reset and re-holds and restricts the front end face of the limit disk 9 in a contact manner. During this process, the first magnetic sheet 15 and the second magnetic sheet 17 are re-engaged;

[0036] After the butterfly gasket 8 is installed, when the winding tape is pulled again, the effective adjustment of its own tension can be realized by increasing the rotation resistance of the first tensioning wheel 3 itself, and the disadvantages of the existing method of adjusting different tensioning wheels can be overcome.

[0037] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
