Description

Technical Field

[0001] The utility model relates to the technical field of fireworks fuses, in particular to a fireworks fuse production and cutting device. Background Art

[0002] After production, fireworks fuses are cut into sections based on actual production needs and then individually installed inside and outside the firework tube. This process is extremely dangerous because the fuses themselves contain large amounts of flammable and explosive materials such as black powder. Fire, static electricity, or friction can ignite them. Furthermore, firework fuses burn very quickly, leaving little time for emergency response. This can easily lead to production accidents, endangering the company's property and the lives of nearby personnel, resulting in significant losses.

[0003] A common device for cutting firework fuses consists of a connecting plate, a hopper, a conveyor, and a cutting frame. The hopper stores coils of firework fuse, while the conveyor delivers the fuse from the hopper to the cutting frame for cutting. The cutting frame typically consists of a blade and a pressure plate. Adjusting the blade's position and cutting force allows for precise cutting of the firework fuse.

[0004] In general, the background technology behind fireworks fuse production and cutting devices involves multiple aspects, including the flammable and explosive properties of fireworks fuses, safety requirements during production, and the development of existing technologies. With the continuous advancement of technology and the increasing emphasis on production safety, we believe that more advanced and safe fireworks fuse production and cutting devices will be developed in the future, providing better protection for production safety in the fireworks industry.

[0005] In existing fireworks fuse production and cutting devices, due to the inherent hardness of the fuse, the fuse is extended by simply rotating the winding roller and the conveyor wheel to facilitate cutting. The fuse is then cut by the cutting blade. However, in actual production, due to the low hardness of the fuse, the fuse bends after being extended for a certain distance, and the degree of bending of each fuse cannot be consistent. This results in the inability to ensure that the cutting position is completely consistent when cutting these fuses, resulting in the inability to ensure that the length of the cut fuse is completely consistent.

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] Reference Figure 1-6 The top of the support frame 2 is provided with a plurality of winding rollers 3, and the top of the support frame 2 is provided with a plurality of winding rollers 3. The top of the processing table 1 is fixedly installed with a support frame 2, and a connecting plate 13 is provided on the top of the support frame 4 for sliding. A traction mechanism is provided between the connecting plate 13 and the support frame 4. A plurality of clamping blocks 14 are slidably installed on the bottom of the connecting plate 13, and a plurality of connecting blocks 14 are fixedly installed on the top of each of the clamping blocks 14. A connecting rod 15 is fixedly installed on both sides of the top of the support frame 4. A connecting frame 22 is fixedly installed on the top of the two connecting frames 22. A guide plate 23 is provided on the guide plate 23. A guide groove 24 is provided on the guide plate 23. The connecting rod 15 is slidably arranged inside the guide groove 24. A plurality of cutting knives 7 are provided on the top of the support frame 4. When the device is used, there are multiple groups of guide grooves 24 on the guide plate 23, and each group includes two guide grooves 24. The two ends of the two guide grooves 24 are far away from each other, and the middle parts are close to each other. In actual use, The two clamping blocks 14 are separated from each other, and the cut lead is put down. Then the connecting plate 13 drives the clamping block 14 and the connecting rod 15 to reset. The clamping and traction of the lead by the two clamping blocks 14 can keep the lead straight when being cut, so that the length of the cut lead can be kept consistent.

[0026] As the preferred technical solution of this embodiment, the traction mechanism includes two support plates 8, and the two ends of the two support plates 8 are respectively slidably installed with mounting blocks 9, a ball screw 10 is provided on the top of one of the support plates 8, and a slide rod 12 is provided on the top of the other support plate 8, and the slide rod 12 is fixedly installed between the two mounting blocks 9, and the ball screw 10 is rotatably installed between the two outer mounting blocks 9, and a motor 11 is fixedly installed on one of the mounting blocks 9 close to the ball screw 10, and the output end of the motor 11 passes through the mounting block 9 and is fixedly connected to the ball screw 10, one end of the connecting plate 13 is threadedly connected to the ball screw 10, and the other end of the connecting plate 13 is slidably connected to the slide rod 12; when the traction mechanism is needed to drive the connecting plate 13 to move, the ball screw 10 is driven to rotate by the output end of the motor 11, thereby driving the connecting plate 13 to move, and the slide rod 12 plays the role of auxiliary movement and limiting.

[0027] As a preferred technical solution of this embodiment, a lifting assembly is provided on the support plate 8, and the lifting assembly includes a driving groove 17, the driving groove 17 is opened on the side wall of the support plate 8, and a guide block 18 is slidably installed inside the driving groove 17, and a support block 19 is fixedly installed on the side wall of the guide block 18, and a first tension spring 20 is fixedly installed on the bottom of the support block 19, and the support block 19 is slidably installed inside the support plate 8, and the bottom end of the first tension spring 20 is fixedly connected to the support plate 8. Support rods 16 are fixedly installed on the bottom of both ends of the connecting plate 13, and the bottom end of the support rod 16 slides with the driving groove 17, and a second tension spring 21 is fixedly connected between the plurality of mounting blocks 9 and the support plate 8; when the connecting plate 13 drives the clamping block 14 to reset, since the two clamping blocks 14 are moved to the position of the lead end, they are still in a state close to each other. At this time, the connecting plate 13 drives the clamping block 14 to reset and then causes the two clamping blocks 14 to squeeze the lead end, causing the lead end to bend. In order to avoid this situation, A guide block 18 is provided at the position where the block 14 is reset and contacts the lead. The guide block 18 is a right-angled triangle with a right angle cut off. When the support rod 16 moves along the drive groove 17 to reset, when it reaches the guide block 18 position, it will move along the hypotenuse of the guide block 18 to the top of the guide block 18, so that the position of the clamping block 14 moves up. When the connecting rod 15 moves to the position where the guide groove 24 moves away from each other, the two clamping blocks 14 move away from each other, and the support block 19 falls after crossing the highest point of the guide block 18. At this time, the lead end is located between the two clamping blocks. When the two clamping blocks 14 clamp the lead ends and move again, in order to ensure that the clamping blocks 14 drive the lead to move smoothly, when the support rod 16 moves to the position of the guide block 18, it enters the notch at the bottom of the guide block 18 to lift the guide block 18, which does not affect the smooth movement of the connecting plate 13, and the guide block 18 will be reset under the action of the first tension spring 20, and guide the connecting plate 13 when the connecting plate 13 is reset. The second tension spring 21 on the mounting block 9 is to allow the ball screw 10 and the slide bar 12 to maintain relatively consistent positions.
