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.

[0021] See also Figure 1-4 The utility model provides a technical solution: a webbing positioning mechanism of a webbing machine, comprising a fixed plate 1, a positioning roller 2 and a driven roller 3, and also comprising a limiting roller 4 and a connecting rod 8. The limiting roller 4 is fixedly arranged on two fixed plates 1 and located below the positioning roller 2. A plurality of positioning sleeves 5 are slidably sleeved on the limiting roller 4. A supporting plate 6 is fixedly arranged between the two fixed plates 1 and located below the limiting roller 4. A plurality of movable plates 7 corresponding to and fixedly connected to each positioning sleeve 5 are slidably arranged on the supporting plate 6. A movable plate 7 located in the middle is fixedly connected to the supporting plate 6. Each movable plate 7 is hingedly connected in a scissor-fork manner through a plurality of connecting rods 8. A control block groove 12 is opened on the side wall of the fixed plate 1 on one side. A control block 11 fixedly connected to a side wall of a movable plate 7 is slidably arranged in the control block groove 12. A control mechanism for controlling the movement of the control block 11 is arranged in the fixed plate 1.

[0022] Specifically, the number of the movable plates 7 is odd, and the movable plate 7 located at the median position is the movable plate 7 fixed to the support plate 6, thereby ensuring the stability of each movable plate 7 and the intervals between the movable plates 7 are consistent.

[0023] Specifically, a slide groove 9 is provided on the support plate 6, and a slider 10 fixedly connected to the movable plate 7 is slidably provided in the slide groove 9. A stabilizing groove 21 is symmetrically provided on the inner wall of the slide groove 9. A stabilizing block 22 fixedly connected to the side wall of the slider 10 is slidably provided in the stabilizing groove 21, thereby ensuring the stability of the movable plate 7 moving on the support plate 6 and preventing the movable plate 7 from detaching from the support plate 6.

[0024] Specifically, the control mechanism includes a screw 14 and a knob 16. A threaded groove 13 is provided at one end of the control block 11 located in the control block groove 12 and is threadedly connected to the screw 14. A rotating groove 15 is provided at the bottom of the control block groove 12 for the screw 14 to pass through and is rotatably connected to the screw 14. The knob 16 is fixedly connected to one end of the screw 14 located outside the rotating groove 15. The screw 14 is rotated by rotating the knob 16. The control block 11 slides in the control block groove 12 through the threaded connection between the screw 14 and the threaded groove 13, and drives the movable plate 7 fixedly connected thereto to move. The spacing between the movable plates 7 is adjusted through the action between the connecting rods 8, thereby adjusting the spacing between the positioning sleeves 5 on the limiting roller 4, which can adapt to the positioning of webbings of different widths.

[0025] Specifically, a limiting ring groove 17 is formed on the inner wall of the rotating groove 15, and a limiting ring 18 fixedly sleeved on the screw rod 14 is rotatably arranged in the limiting ring groove 17. The limiting ring groove 17 and the limiting ring 18 prevent the screw rod 14 from axial movement.

[0026] Specifically, the inner wall of the control block groove 12 is symmetrically provided with a limit groove 19, and a limit block 20 fixedly connected to the side wall of the control block 11 is slidably provided in the limit groove 19. The control block 11 is prevented from moving out of the control block groove 12 by the limiting of the limit groove 19 and the limit block 20.

[0027] A specific application example of this embodiment is:

[0028] When the device is in use, the webbing pulled out from the positioning roller 2 is wound around the limiting roller 4 and positioned between every two positioning sleeves 5. The limiting between the positioning sleeves 5 ensures that the webbing is adequately positioned to avoid entanglement between the webbings. The knob 16 is turned to drive the screw rod 14 to rotate. The threaded connection between the screw rod 14 and the thread groove 13 allows the control block 11 to slide in the control block groove 12 and drives the movable plate 7 fixedly connected thereto to move. The spacing between the movable plates 7 is adjusted through the action between the connecting rods 8, thereby adjusting the spacing between the positioning sleeves 5 on the limiting roller 4. This can adapt to the positioning of webbings of different widths and improve practicality.
