[0032] Please see Figure 1-4 This utility model provides a technical solution: a multifunctional fireworks fuse twisting device, including a base 1 and a support plate 3;
[0033] A tensioning device is provided on the support plate 3;
[0034] The tensioning device includes a sliding seat 9, a fixed mounting block 16, a rotating mounting block 17, and a second hydraulic telescopic rod 15. A support plate 3 is fixedly mounted on the upper surface of the base 1. The fixed mounting block 16 is fixedly connected to the outer wall of the rear end of the support plate 3. The lower outer wall of the rotating mounting block 17 is rotatably connected to the inner upper end of the fixed mounting block 16. The second hydraulic telescopic rod 15 is fixedly mounted on the outer wall of the rotating mounting block 17 on the side away from the fixed mounting block 16. A movable rod 4 is rotatably connected inside the groove at the rear end of the support plate 3. A movable block 18 is fixedly connected to the output end of the second hydraulic telescopic rod 15. The movable block 18 is rotatably connected to the fixed block on the outer wall of the movable rod 4 on the side away from the support plate 3. Next, the outer wall of the end of the movable rod 4 away from the support plate 3 is fixedly connected to the support frame 11. The groove of the outer wall of the end of the support frame 11 away from the movable rod 4 is equipped with the first hydraulic telescopic 5. The outer walls of the tapered blocks on both sides of the upper end of the sliding seat 9 are slidably connected to the two tapered grooves opened on the lower surface of the support frame 11. The support frame 11 is hollow. The upper protrusion of the sliding seat 9 is located inside the support frame 11. The output end of the first hydraulic telescopic 5 slides to the inside of the support frame 11 and is fixedly connected to the outer wall of the upper protrusion of the sliding seat 9. The lower outer wall of the sliding seat 9 is rotatably connected to the guide frame 12. The lower inner wall of the guide frame 12 is rotatably connected to two guide wheels.
[0035] Among them, a take-up assembly 2 is installed on the outer wall of the support plate 3 away from the movable rod 4, a fixed plate 8 is fixedly connected to the upper surface of the base 1 away from the support plate 3, a second motor 10 is installed on the fixed plate of the support plate 3 away from the take-up assembly 2, the output end of the second motor 10 extends rotatably to the outside of the support plate 3 and is connected to the rotating shaft on the take-up assembly 2, a rotating seat 14 is rotatably connected to the outer wall of the fixed plate 8 near the support frame 11, four wire feeding assemblies 13 are installed inside the rotating seat 14, a first motor 7 is installed on the outer wall of the fixed plate 8 away from the rotating seat 14, the output end of the first motor 7 extends rotatably to the outside of the fixed plate 8 and is fixedly connected to the outer wall of the rotating seat 14, and a wire harness ring 6 is fixedly connected to the upper surface of the base 1.
[0036] Furthermore, when using this device, it is started by connecting to an external power source. When using the multi-functional fireworks fuse twisting device, the untwisted fireworks fuse raw material is first placed on the release assembly 13 inside the rotating seat 14. Then, the released fuse is preliminarily tidied by the wire binding ring 6 and passes through the two guide wheels at the lower end of the guide frame 12. At this time, the second hydraulic telescopic rod 15 is activated. The extension and retraction of the second hydraulic telescopic rod 15 drives the movable block 18 to move, causing the movable rod 4 to rotate, which in turn pushes the support frame 11 to move, adjusting the position and angle of the guide frame 12, applying appropriate tension to the fuse, and ensuring that the fuse remains taut during the twisting process. Then, the first motor 7 drives the rotating seat 14 to rotate, while the second motor 10 drives the rotating shaft of the take-up assembly 2 to rotate, twisting the fuse and starting to wind it up. During the winding process of the take-up assembly 2, the fuse is continuously released from the release assembly 13, allowing the fuse to be released smoothly. At the same time, the extension and retraction of the first hydraulic telescopic rod 5 drives the sliding seat 9 to slide back and forth inside the support frame 11. The take-up is achieved through the cooperation between the sliding seat 9 and the guide frame 12.
[0037] The tensioning device uses the second hydraulic telescopic rod 15 to extend and retract, which moves the movable block 18, causing the movable rod 4 to rotate. This, in turn, pushes the support frame 11 to move, adjusting the position and angle of the guide frame 12. This applies appropriate tension to the lead wire, ensuring that the lead wire remains taut during twisting. This prevents the wire from becoming loose and tangled during release, which could lead to uneven twisting or even loosening of the lead wire, thus reducing the practicality and flexibility of the equipment.
