Abstract
Description
Technical Field
[0001] This utility model relates to a device for straightening and painting fireworks fuses. Background Technology
[0002] In existing technologies, fuse processing equipment involves winding the finished fuse (after coating and drying the semi-finished fuse) onto a take-up reel to form a coil, as illustrated in the "Fuse Production Machine for Fireworks and Firecrackers" disclosed in Chinese Utility Model Patent Document CN 201694971 U, published on January 5, 2011. However, winding the finished fuse damages the rigidity and inflexibility of the coated fuse, leading to inconvenience or unsuitability in later fireworks production. Currently, the production of this type of straight fuse without winding is mainly done manually, resulting in high labor load and low production efficiency; furthermore, fuses are flammable, posing significant safety hazards to production workers. Utility Model Content
[0003] To address the aforementioned drawbacks, the technical problem this invention aims to solve is to provide a device for straightening and painting fireworks fuses. The technical solution adopted by this invention is a fireworks fuse straightening and painting device, comprising an annular slide rail positioned above a conveying mechanism, several sliders mounted on the annular slide rail, and a motor driving the sliders to move in a circular motion along the annular slide rail via a chain assembly or a synchronous belt assembly; each slider is equipped with a wire-winding roller, and each roller is correspondingly provided with a paint hopper that moves synchronously with the roller in the circular motion; the paint hopper has an inlet hole and an outlet hole for the fuse to pass through.
[0004] The inner ring of the annular slide rail is provided with a first winding post and a second winding post at both ends. Both winding posts are provided with a cutting mechanism to cut off all the leads that pass over the winding post. A lead end fixing member is provided near the first winding post. After the lead on each wire roller passes through the paint hopper, the lead end is fixed on the lead end fixing member. The inner ring of the annular slide rail is provided with a hollow part. The lead cut by the cutting mechanism falls through the hollow part onto the conveying mechanism.
[0005] The beneficial effects of this utility model are that the lead wire ends on each wire roller are fixed on the lead wire end fixing member, and then the wire roller moves in a circular motion around the annular slide rail. During the motion, the lead wire wound on the wire roller is continuously unwound and drawn out, and then passes through the paint hopper to complete the painting, and then is wound on two winding posts; the cutting mechanism cuts off all the lead wires that pass over the winding posts, and the cut lead wires fall from the hollow part onto the conveyor belt, completing the straightening and painting process of the fireworks lead wire.
[0006] As can be seen from the above, this utility model provides a device for straightening and painting fireworks fuses. It has a high degree of automation, which improves the processing efficiency of straight fuses. It effectively reduces the manual labor load and reduces the use of manual labor, thereby greatly reducing personal safety hazards.
[0007] In one embodiment, the cutting mechanism includes a cutting blade with the blade facing downwards. The first winding post and the second winding post are both provided with guide grooves distributed along the axial direction of the winding post. One side of the cutting blade is embedded in the guide groove and moves up and down along the guide groove.
[0008] In one embodiment, the first winding post and the second winding post are provided with a lifting mechanism.
[0009] In one embodiment, the conveying mechanism consists of a belt conveyor and a roller conveyor connected end to end, with the annular slide rail located above the belt conveyor and the connection between the belt conveyor and the roller conveyor close to the second winding post.
[0010] In one embodiment, the lead end fixing member is a clamp that fixes the lead end.
[0011] In one embodiment, the paint hopper is fixed on a roller.

[0027] See appendix Figure 1-8 This illustrates a specific structure of the present invention. The straightening and painting device for the fireworks fuse includes an annular slide rail 2 positioned above the conveying mechanism. In this example, the conveying mechanism consists of a belt conveyor 1 and a roller conveyor 22 connected end-to-end, with the annular slide rail 2 located above the belt conveyor 1. The belt conveyor 1 is equipped with a tension adjustment component 6.
[0028] like Figure 8 As shown, nine sliders 24 are mounted on the annular slide rail 2. The motor 8 drives the sliders 24 to move in a circular motion along the annular slide rail 2 through the reducer, sprocket 23, and chain 25.
[0029] Please combine Figure 6Each slider 24 is equipped with a take-up roller 3 (not shown in the figure) for unwinding the lead wire. The roller 3 has a bearing 14 to facilitate its smooth rotation for unwinding the lead wire. Each roller 3 is correspondingly equipped with a paint hopper 4 that performs the circular motion synchronously with the roller. The paint hopper 4 has an inlet hole and an outlet hole for the lead wire to pass through. As the lead wire passes through the inlet hole and outlet hole, paint adheres to it, completing the painting process. In this example, the paint hopper 4 is fixedly mounted on the base of the roller 3, such as by bolts.
[0030] The inner ring of the annular slide rail 2 is provided with a first winding post 7 and a second winding post 16 at its two ends. In the example, the first winding post 7 and the second winding post 16 are respectively driven by the winding post cylinder 13 to perform lifting and lowering movements. The winding post cylinder 13 is mounted on the frame 12.
[0031] Both the first winding post 7 and the second winding post 16 are equipped with a cutting mechanism to cut all leads that pass over the two winding posts. In this example, the cutting mechanism includes a cutting blade 10 with its blade facing downwards. Guide grooves 9 are provided on both the first winding post 7 and the second winding post 16, distributed along the axial direction of the winding post. One side of the cutting blade 10 is embedded in the guide groove 9 and moves up and down along the guide groove 9 under the drive of the cutting blade cylinder 11. The cutting blade cylinder 11 is mounted on the frame 12.
[0032] A lead end fixing member 5 is provided near the first winding post 7. In this example, the lead end fixing member 5 is a clamp for fixing the lead end.
[0033] The lead wire on each roller 3 passes through the paint hopper 4 and the end of the lead wire is fixed to the lead wire end fixing member 5. The inner ring of the annular slide rail 2 is provided with a hollow part 15, and the lead wire cut by the cutter 10 falls onto the belt conveyor 1 through the hollow part 15.
[0034] In this example, to bundle and cut the straightened and painted lead wires at fixed intervals as needed, a ring-shaped bundling mechanism 18 and a lead wire bundle cutting mechanism are also provided on the roller conveyor belt 22 located behind the second winding post 16. The cutting mechanism includes a cutter 20 and an anvil 21 arranged vertically. The cutter 20 is driven by a cutter 19 to move up and down. The anvil 21 is embedded in the roller conveyor belt 22. When the lead wire bundle passes through the anvil, the cutter 19 moves downward and cooperates with the anvil 21 to cut the lead wire bundle.
[0035] The circular strapping mechanism 18 is a commonly used piece of equipment that automatically tightens and straps items (multiple leads) around their perimeter using strapping tape or rope. It is also known as a packing machine, bundling machine, sling machine, or strapping machine. Product names on Taobao include "strapping machine," "fine rope strapping machine," and "side-swinging opening and closing strapping machine," etc., which will not be elaborated further.
[0036] The working process of the above-mentioned device includes the following steps:
[0037] The nine lead wire ends on the nine rollers 3 of S1 are unwound from the rollers 3 and passed through the paint hopper 4. Before starting the machine, the nine lead wire ends are fixed on the lead wire end fixing piece 5. There are bolts on the clamp that can be manually tightened to tighten the lead wire ends.
[0038] S2 motor 8 drives chain 25 to drive slider 24 to perform circular motion on annular slide rail 2. As the slider moves, the nine lead wires on the nine rollers 3 continuously unwind, pass through paint hopper 4 for painting, and wind around the first winding post 7 and the second winding post 16 until all lead wires on each roller 3 have been unwinded and completed. During the above process, the paint is dried and shaped.
[0039] After winding S3 is completed, the first winding post 7 and the second winding post 16 rise, and the two cutters 10 descend to cut all the lead wires that have passed over the two winding posts. At this time, the connection between the lead wire end fixed by the lead wire end fixing member 5 and the wire roller 4 is broken. The long straight lead wires, which have been cut at both ends, fall through the hollow part 15 onto the belt conveyor 1 and the roller conveyor 22 under the action of gravity.
[0040] In the example, the coordinated movement of the winding post rising and the cutter falling improves the reliability of cutting all leads and removing long straight leads.
[0041] S4 belt conveyor 1 and roller conveyor 22 operate to transport all the long straight leads to the ring bundling mechanism 18. At predetermined length intervals, all the long straight leads are ring-bundled to form a bundled lead wire. The predetermined length is set according to actual needs. In this example, the connection between belt conveyor 1 and roller conveyor 22 is close to the second winding post 16 to facilitate lead wire transport.
[0042] S5 As the lead wire bundle continues to move past the anvil 21, the cutter 20 cuts the lead wire bundle at a fixed distance, obtaining a finished straight lead wire bundle of a set length that is then bundled. This bundle can then be supplied to fireworks manufacturers.
[0043] The embodiments of the present invention disclosed above are merely illustrative of the present invention. The embodiments do not exhaustively describe all details, nor do they limit the present invention to the specific implementations described. Obviously, many modifications and variations can be made based on the content of this specification. This specification selects and describes these embodiments in detail with reference to the accompanying drawings to better explain the principles and practical applications of the present invention, thereby enabling those skilled in the art to better understand and utilize the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present invention. Therefore, the present invention is limited only to the claims and their full scope and equivalents, and not to the specific embodiments disclosed.
