[0029] See attached Figure 1-8 , reflecting a specific structure of the present invention. The fireworks straight lead wire painting cutting and bundling device includes an annular slide rail 2 arranged above the conveying mechanism. In the example, the conveying mechanism is composed of a belt conveyor belt 1 and a roller conveyor belt 22 connected end to end, and the annular slide rail 2 is located above the belt conveyor belt 1. The belt conveyor belt 1 is provided with a tension adjustment component 6

[0030] like Figure 8 As shown, nine sliders 24 are mounted on the annular slide rail 2 , and the motor 8 drives the sliders 24 to perform circular motion along the annular slide rail 2 through a reducer, a sprocket 23 , and a chain 25 .

[0031] Please combine Figure 6, each slider 24 is provided with a wire roller 3 for winding the lead wire (not shown in the figure), and the wire roller 3 is provided with a bearing 14 to facilitate its light rotation and unwinding of the lead wire. Each wire roller 3 is provided with a paint bucket 4 that performs the circular motion synchronously with the wire roller, and the paint bucket 4 is provided with an inlet hole and an outlet hole for the lead wire to pass through. When the lead wire passes through the inlet hole and the outlet hole, the paint is adhered to the paint bucket 4 to complete the painting work. In the example, the paint bucket 4 is fixed on the seat of the wire roller 3, such as bolt connection.

[0032] The inner ring of the annular slide rail 2 has a first winding post 7 and a second winding post 16 at both ends. In the example, the first winding post 7 and the second winding post 16 are driven by a winding post cylinder 13 to perform lifting motion, and the winding post cylinder 13 is installed on the frame 12.

[0033] The first winding post 7 and the second winding post 16 are both provided with a cutter mechanism for cutting off all the leads wound around the two winding posts: in the example, the cutter mechanism comprises a cutter 10 with a blade facing downward, and the first winding post 7 and the second winding post 16 are both provided with guide grooves 9 distributed along the axial direction of the winding posts, and one side of the cutter 10 is embedded in the guide groove 9 and moves up and down along the guide groove 9 under the drive of the cutter cylinder 11. The cutter cylinder 11 is installed on the frame 12.

[0034] A lead head fixing part 5 is provided near the first winding post 7. In the example, the lead head fixing part 5 is a clamp for fixing the lead end.

[0035] The lead wire on each wire roller 3 passes through the paint bucket 4 and the lead wire end is fixed on the lead wire head fixing member 5. The inner ring of the annular slide rail 2 is provided with a hollow portion 15, and the lead wire cut by the cutter 10 falls onto the belt conveyor 1 through the hollow portion 15.

[0036] The roller conveyor belt 22 behind the second winding column 16 is provided with an annular bundling mechanism 18 and a cutting mechanism for the lead bundle. The cutting mechanism includes a cutter 20 and an anvil 21 correspondingly arranged above and below. The cutter 20 is driven by the cutter 19 to move up and down. The anvil 21 is embedded in the roller conveyor belt 22. When the lead bundle passes through the anvil, the cutter 19 moves downward to cooperate with the anvil 21 to cut the lead bundle.

[0037] The ring strapping mechanism 18 is a commonly used device that uses strapping tape or rope to wrap around the periphery of an object (multiple leads) to automatically tighten and strap. It is also called a baler, a baler, a strapping machine, a strapping machine or a strapping machine. Taobao product names such as "strapping machine", "string strapping machine", "side swing opening and closing strapping machine", etc. are not repeated here.

[0038] The workflow of the above device includes the following steps:

[0039] S1 The nine lead wire ends on the nine wire rollers 3 are unwound from the wire rollers 3 and led through the paint hopper 4. Before starting the machine, the nine lead wire ends are fixed on the lead wire head fixing parts 5. There are bolts on the clamps to manually tighten the lead wire ends.

[0040] The S2 motor 8 drives the chain 25 to drive the slider 24 to perform circular motion on the annular slide rail 2. The nine lead wires on the nine wire rollers 3 that move with the slider are continuously unwound, passed through the paint hopper 4 for painting, and wound around the first winding pole 7 and the second winding pole 16 until all the lead wires on each wire roller 3 have been unwound and wound, and the paint film is dried and shaped in the above process.

[0041] After S3 winding is completed, the first winding pole 7 and the second winding pole 16 are raised, and the two cutting knives 10 are moved downward to cut off all the leads wound around the two winding poles. At this time, the connection between the lead end fixed by the lead head fixing member 5 and the wire roller 4 is disconnected. The long straight lead with both ends cut off falls onto the belt conveyor 1 and the roller conveyor 22 through the hollow portion 15 under the action of gravity.

[0042] In the example, the coordination of the rising of the winding pole and the falling of the cutting knife is conducive to improving the reliability of the cutting work of all the leads and the dropping work of the long straight leads.

[0043] S4 The belt conveyor 1 and the roller conveyor 22 are in motion to convey all the long straight leads to the ring bundling mechanism 18. All the long straight leads are ring-bundled and packaged at intervals of a set length to obtain a bundled lead bundle. The set length is set according to actual needs. In the example, the connection between the belt conveyor 1 and the roller conveyor 22 is close to the second winding column 16 to facilitate the conveyance of the leads.

[0044] S5 When the fuse bundle continues to move through the chopping board 21, the cutter 20 cuts the fuse bundle at a fixed distance to obtain a bundled finished straight lead bundle of a set length, which can be supplied to fireworks companies for use.
