Description

Technical Field

[0001] This utility model relates to the field of fireworks fuse production, and in particular to a fireworks double fuse winding device. Background Technology

[0002] Double fuses are a type of firecracker fuse. Compared to traditional single fuses, double fuses have better resistance to breakage and make firecrackers neater and more aesthetically pleasing during installation and use. Double fuses are generally made by winding two independent single fuses together to form an intertwined spiral shape using a winding machine. The wound double fuses are then soaked in a pool filled with wet nitrate solution to enhance the fuse strength and promote uniform combustion. Finally, the double fuses soaked in the wet nitrate solution are dried and wound up.

[0003] However, in existing dual-lead winding devices, the wet nitric acid solution in the wet nitric acid tank will settle over time during winding, causing the solute to settle to the bottom. This results in uneven wet nitric acid solution covering the entire lead wire, leading to poor overall product quality. Utility Model Content

[0027] Example 1: A double-lead winding device for fireworks, such as Figures 1-6 As shown, it includes, base frame 1;

[0028] The fixing frame 2 is fixed to the top of the base frame 1, and the fixing frame 2 is hollow;

[0031] The housing 5 is fixed to the top of the base frame 1 and is hollow.

[0032] The stranding mechanism is installed on the fixed frame 2, which is used to wind two sets of single leads into a set of double leads;

[0033] A winding mechanism is provided on the fixing frame 2 and the housing 5, which is used to wind up the double lead wire after it has been wound.

[0034] The stranding mechanism includes a turntable 6 rotatably connected to a fixed frame 2, with two symmetrically arranged circular holes on the turntable 6; a branch frame 7 bolted to one side of the turntable 6, with two symmetrically arranged wire holes on the branch frame 7; two mounting brackets 8 welded to the other side of the turntable 6; two rubber pillars 9 rotatably connected to the two mounting brackets 8 respectively, the rubber pillars 9 being used to hold a single lead wire coil; a motor 10 fixed to the lower part of the fixed frame 2; a gear 11 fixed to the output shaft of the motor 10; and a gear 12 fixed to the outer edge of the turntable 6. Gear 11 and gear 12 mesh and are both located within the fixed frame 2. The motor 10 drives gear 12 to rotate through gear 11, thereby driving the turntable 6 to rotate.

[0035] The winding mechanism includes an internally threaded sleeve 13 rotatably connected to the housing 5, a locking rod 14 threadedly connected to the internally threaded sleeve 13, the locking rod 14 clamping the empty coil through the thread, a rotating shaft 15 rotatably connected between the fixed frame 2 and the housing 5, a gear 16 fixed to the rotating shaft 15, the gear 16 meshing with a gear and located inside the fixed frame 2, a gear 17 fixed to the rotating shaft 15, and a gear 18 fixed to the internally threaded sleeve 13, the gear 17 and gear 18 meshing, the gear 12 driving the rotating shaft 1 to rotate through the gear 16, and then driving the internally threaded sleeve 13 to rotate through the gear 17 and gear 18.

[0036] Initially, the workers filled the wet nitrification tank 3 with wet nitrification solution, unscrewed the locking rod 14, inserted the empty reel, and then tightened the locking rod 14 with the reel inserted onto the internal thread sleeve 13. Next, they inserted two single-lead wires into two rubber posts 9, and then passed the two single-lead wires sequentially through the two round holes on the turntable 6 and the two wire holes on the branch frame 7. They then combined the two single-lead wires into a single strand and twisted it into a braid. Finally, they passed the combined double-lead wire sequentially through several holes in the wet nitrification tank 3. The wire hole and dryer 4 are used to finally tie the combined double lead wire to the empty winding spool on the locking rod 14. After winding begins, the operator starts the motor 10 and the dryer 4. The output shaft of the motor 10 rotates, which drives gear 11 to rotate. Gear 11 rotates, which drives gear 2 to rotate. Gear 2 to rotate, which drives the turntable 6 to rotate. The turntable 6 rotates, which drives the branch frame 7, the mounting frame 8, the rubber column 9, and the two rolls of single lead wire to rotate. The two rolls of single lead wire rotate and form an intertwined spiral shape. Gear 2 12 rotates, driving gear 3 16 to rotate. Gear 3 16 rotates, driving shaft 1 15 to rotate. Shaft 1 15 rotates, driving gear 4 17 to rotate. Gear 4 17 rotates, driving gear 5 18 to rotate. Gear 5 18 rotates, driving internal thread sleeve 13 to rotate. Internal thread sleeve 13 rotates, driving locking rod 14 and empty winding wheel to rotate. Through the above operations, two rolls of single lead wire can be wound into a double lead wire and wound up. When the empty winding wheel winds up the double lead wire, under the action of several wire holes in the wet nitrate tank 3, the double lead wire will enter the bottom of the wet nitrate tank 3 and be soaked in a layer of wet nitrate solution before entering the dryer 4 for drying. When the two single lead wires are about to be wound up and the ends pass through the two wire holes of the branch frame 7, the workers tie the ends of the two single lead wires into a knot. When the double lead wire is completely wound up, the workers turn off the motor 10 and the dryer 4, remove the two empty winding wheels and the winding wheel with the double lead wire, to facilitate the next winding.

[0037] Example 2: Based on Example 1, such as Figure 1 , Figure 6 and Figure 7 As shown, it also includes a homogenizing mechanism disposed on the wet nitrate tank 3 and the rotating shaft 15. The homogenizing mechanism is used to intermittently agitate the wet nitrate solution in the wet nitrate tank 3. The homogenizing mechanism includes a cam 19 fixed to the rotating shaft 15, a transmission frame 20 slidably connected to the wet nitrate tank 3, one side of the transmission frame 20 contacting the cam 19, a return spring 21 disposed between the transmission frame 20 and the wet nitrate tank 3, the rotating shaft 15 driving the cam 19 to rotate, thereby squeezing the transmission frame 20 and the return spring 21, and a rotating assembly disposed on the wet nitrate tank 3 and the transmission frame 20.

[0038] The rotating assembly includes two sets of racks 22 fixed to the transmission frame 20, and two rotating shafts 23 rotatably connected to the wet nitrification tank 3. The two rotating shafts 23 are symmetrically arranged. Each rotating shaft 23 has two gears 24 fixedly connected to it, and several stirring racks 25 are fixedly connected to each rotating shaft 23. The transmission frame 20 drives the gears 24 to rotate through the racks 22, and then drives the stirring racks 25 to rotate through the rotating shafts 23.

[0039] When the rotating shaft 15 rotates, it drives the cam 19 to rotate. The rotation of the cam 19 pushes the transmission frame 20, compressing the return spring 21. The movement of the transmission frame 20 drives the rack 22 to move, which in turn drives the gear 6 24 to rotate. The rotation of the gear 6 24 drives the rotating shaft 23 to rotate, which in turn drives the stirring frame 25 to rotate. Through the above operation, the wet nitrate solution in the wet nitrate tank 3 can be intermittently stirred, reducing the probability of sedimentation of the wet nitrate solution, improving the uniformity of the wet nitrate solution in the lead-in foam, and enhancing the overall product quality. The cam 19 continues to rotate and disengages from the transmission frame 20. The return spring 21 rebounds and drives the transmission frame 20 to move in the opposite direction. The reverse movement of the transmission frame 20 drives the rack 22 to move in the opposite direction, which in turn drives the gear 6 24 to rotate in the opposite direction. The reverse rotation of the gear 6 24 drives the rotating shaft 23 to rotate in the opposite direction, which in turn drives the stirring frame 25 to rotate in the opposite direction.
