DETAILED DESCRIPTION

[0031] The following will be described in detail in combination with the drawings Figures 1-4 The present application will be further described in detail.

[0032] The embodiment of the present application discloses a cloth winding device with a tensioning mechanism. Referring to Figure 1 and Figure 2 A cloth winding device with a tensioning mechanism includes a winding device body 1, and first and second fixed blocks 2 and 3 are respectively fixed on the inner walls of the upper end of the winding device body 1. A moving rod 5 is arranged between the first and second fixed blocks 2 and 3, and the moving rod 5 is movably connected with the first fixed block 2. An air cylinder 4 is arranged on the side of the first fixed block 2 away from the second fixed block 3, the shell of the air cylinder 4 is installed on the winding device body 1 by bolts, and the cylinder shaft of the air cylinder 4 is connected with one end of the moving rod 5 in the length direction by bolts. The cylinder shaft of the air cylinder 4 is in sliding fit with the first fixed block 2, so as to drive the moving rod 5 to reciprocate along the length direction.

[0033] The surface of the moving rod 5 is hingedly connected with an adjusting plate 6, and the adjusting plate 6 is provided with multiple groups, in this embodiment, four adjusting plates 6 are uniformly arranged around the moving rod 5. The length direction of the four adjusting plates 6 is parallel to the length direction of the moving rod 5, and the explosion-proof film body 17 is attached to the outer side wall of the adjusting plate 6.

[0034] The winding device body 1 is further provided with a supporting roller 10, the length direction of the supporting roller 10 is parallel to the length direction of the moving rod 5, both ends of the length direction of the supporting roller 10 are fixedly connected with the winding device body 1 through bolts, and the surface of the supporting roller 10 is smooth. Both ends of the supporting roller 10 are slidably sleeved with an adjusting ring 11, and one end of the adjusting ring 11 is fixedly provided with a partition plate 16. There is a gap between the partition plate 16 and the outer side wall of the supporting roller 10, and the explosion-proof film body 17 is clamped between the partition plate 16 and the supporting roller 10. The length of the partition plate 16 is greater than the length of the adjusting ring 11.

[0035] Referring to Figure 1 and Figure 4 , the explosion-proof film production equipment is arranged at the front side of the moving rod 5, the supporting roller 10 is arranged below the front side of the moving rod 5, and the winding device is arranged at the rear of the moving rod 5. After the explosion-proof film body 17 leaves the explosion-proof film production equipment, it first passes through the gap between the partition plate 16 and the outer side wall of the supporting roller 10, then abuts against the outer side wall of the adjusting plate 6, passes around the moving rod 5, and then enters the winding device for winding.

[0036] By starting the air cylinder 4, the moving rod 5 drives the four groups of adjusting plates 6 to move synchronously inward or outward inside the surface of the corresponding one end of the first fixed block 2 and the second fixed block 3, so that the multiple groups of adjusting plates 6 contract and expand outward with the moving rod 5 as the center. By changing the position of the adjusting plate 6, the adjusting plate 6 generates a certain extrusion force on the explosion-proof film body 17, so that the explosion-proof film body 17 is in a taut state with the supporting roller 10. This operation can adjust the tension of the explosion-proof film body 17, improve the flatness of the explosion-proof film winding, and improve the convenience and applicability of the equipment to a certain extent. By moving the two adjusting rings 11 on the surface of the supporting roller 10, the position of the partition plate 16 is limited to the explosion-proof film body 17, so as to avoid the position deviation of the explosion-proof film body 17 during winding, and maintain the winding state of the explosion-proof film body 17.

[0037] Referring to Figure 2The surface of the moving rod 5 is sleeved with a sleeve 7, the length of the moving rod 5 is less than the length of the sleeve 7, and a plurality of grooves are formed in the surface of the sleeve 7. The two ends of the sleeve 7 are fixed on the surface of the end of the first fixed block 2 and the second fixed block 3 close to each other. The surface of the moving rod 5 is provided with a plurality of hinged blocks 8, and the position of the hinged block 8 is inside the groove. Through the cooperation of the sleeve 7, the moving rod 5 and the hinged block 8 can be moved forward or backward inside the groove, and the stability of the moving rod 5 during movement is improved.

[0038] Referring to Figure 2 The two ends of the adjusting plate 6 are fixed with T-shaped blocks 9, and the two groups of T-shaped blocks 9 are respectively slidingly engaged in the inside of the end of the first fixed block 2 and the second fixed block 3 close to each other. Through the cooperation of the two groups of T-shaped blocks 9, when the adjusting plate 6 moves inward or outward, a certain clamping effect can be achieved, so that the adjusting plate 6 does not deviate from the original position, and the setting keeps the synchronism of the movement of the plurality of adjusting plates 6.

[0039] Referring to Figure 3 and Figure 4 The lower end of the supporting roller 10 is provided with a sliding groove 14, and the inner wall of the adjusting ring 11 is provided with a sliding block 15, and the surface of the sliding groove 14 is matched with the surface of the sliding block 15. The two ends of the supporting roller 10 are slidingly inserted with clamping columns 18, and the upper end of one end of the clamping column 18 is threadedly connected with a second bolt 19. The lower end of the motor 20 is fixedly connected with a group of clamping columns 18, and the lower end of the second bolt 19 is threadedly connected with the upper end of the supporting roller 10. The two ends of the supporting roller 10 are provided with clamping blocks, and the surface of the clamping block is matched with the inner wall of one end of the clamping column 18. The upper end of the clamping block is threadedly connected with the second bolt 19. The surface of the rubber pad 13 is slidingly engaged on the inner wall of the adjusting ring 11, and the lower end surface of the rubber pad 13 is matched with the upper end surface of the supporting roller 10.

[0040] Through the cooperation of the sliding groove 14 and the sliding block 15, when the adjusting ring 11 moves on the surface of the supporting roller 10, the sliding block 15 can move on the surface of the sliding groove 14, so that the adjusting ring 11 is more stable during movement, and the position of the baffle 16 is prevented from deviating when the baffle 16 protects the position of the explosion-proof membrane body 17. By rotating the first bolt 12 to make the rubber pad 13 match with the adjusting ring 11, the friction between the adjusting ring 11 and the supporting roller 10 is improved, and the position of the adjusting ring 11 and the supporting roller 10 is fixed. Through the cooperation of the adjusting ring 11 and the baffle 16, the device can not only limit the position of the explosion-proof membrane body 17, but also maintain the form when the explosion-proof membrane body 17 is in a multi-layer rolling state.

[0041] The implementation principle of the cloth winding device with the tensioning mechanism is as follows: when the device is used, first, the device is moved to a suitable position, then the position of the adjusting ring 11 on the surface of the supporting roller 10 is moved, when the position size between the two groups of adjusting rings 11 is adapted to the width size of the explosion-proof film body 17, the rubber pad 13 is rotated to be attached to the surface of the supporting roller 10, thereby fixing the position of the adjusting ring 11. One end of the explosion-proof film body 17 to be wound is manually pulled, so that it is sequentially attached to the surface of the adjusting plate 6 and connected with the supporting roller 10 (manually fixed or wound for several turns), then the moving rod 5 is driven by the air cylinder 4 to move forward or backward, thereby driving the multiple adjusting plates 6 to be synchronously adjusted inward or outward, so as to adjust the tight and flat state of the explosion-proof film body 17. The flatness of the explosion-proof film winding is improved. When the explosion-proof film is completed, the second bolt 19 is rotated, and the supporting roller 10 is taken out from the inside of the two groups of clamping columns 18, thereby completing the disassembly of the supporting roller 10.

[0042] The above are preferred embodiments of the present application, and do not limit the protection scope of the present application, therefore: equivalent changes made according to the structure, shape, principle of the present application should be covered in the protection scope of the present application.
