It is a dedicated device for marking wiring in electrical control, power distribution equipment, and integrated cabling projects, and is widely used in industries such as switches, locomotives, machine tools, power, telecommunications, pharmaceuticals, and steel.

[0003] When using a wire marking machine to print labels on pipelines, the pipelines need to be continuously fed through the machine. However, in actual operation, it has been found that the pipelines to be printed are usually wound on the rollers. After the pipelines are unwound on the rollers, they often have twists and bends. When they pass through the wire marking machine for printing, the printing effect is affected, and even feeding jams may occur. Therefore, this application proposes an auxiliary feeding structure for wire marking machines. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an auxiliary feeding structure for wire marking machines, which aims to solve the technical problems of reduced printing effect and feeding jam caused by the twisting and bending of the pipeline when it passes through the wire marking machine. Technical solution

[0005] To solve the above-mentioned technical problems, this utility model provides an auxiliary feeding structure for a wire marking machine, including a feeding box mounted on the main housing of the wire marking machine. The bottom of the feeding box facing the main housing of the wire marking machine has a second opening, and the middle of the feeding box away from the main housing of the wire marking machine has a first opening. A first guide wheel is rotatably installed inside the feeding box near the first opening. A pair of first guide wheels are arranged side by side. A pair of second guide wheels is rotatably installed inside the feeding box near the second opening. The pair of second guide wheels are perpendicular to the pair of first guide wheels. A pressure wheel is provided above the pair of first guide wheels. A support member for elastically pressing down on the pressure wheel is provided at the top of the feeding box.

[0006] Preferably, a connecting shaft is fixed at the bottom end of the feed box facing the main housing of the wire marking machine, and a bushing is fitted on the connecting shaft. The bushing is fixed below the feed inlet of the main housing of the wire marking machine.

[0007] Preferably, the end of the connecting shaft is provided with an end block, the bushing is rotatably sleeved with the end block, the bushing sidewall is threaded with a clamping bolt that can abut against the end block, and the outer sidewall of the bushing is also provided with an ear block that is bolted to the main housing of the wire marking machine.

[0011] Preferably, an iron sheet is embedded at the bottom of the cover plate, and a magnetic column is provided at the bottom of the feed box at a position corresponding to the iron sheet. Beneficial effects

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention utilizes a pair of first and second guide wheels within the feed box. The filament to be printed passes sequentially through a first opening, between the clamping wheel and the pair of first guide wheels, and between the pair of second guide wheels. It then exits the feed box through the second opening and enters the feed inlet of the wire marking machine's main housing. During the printing process, a spring pushes a connecting rod, causing the clamping wheel to press down. The filament is taut between the clamping wheel and the pair of first guide wheels. The second guide wheels then guide the filament, allowing it to enter the main housing of the wire marking machine smoothly and evenly for printing. This ensures both effective printing and smooth operation, effectively solving the problem of feed jamming caused by twisted or bent filaments.

[0013] In this invention, by rotating the connecting shaft and bushing together, after the pipeline printing is completed, the tightening bolts are loosened, and the feed box can be rotated down to be level with the main housing of the wire marking machine, thereby realizing the folding of the feed box, reducing the footprint, and making it convenient to carry and store.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] This embodiment provides an auxiliary feeding structure for a wire marking machine, the schematic diagram of which is shown below. Figures 1-5 As shown, the feeding box 2 is mounted on the main housing 1 of the wire marking machine. Specifically, a connecting shaft 7 is fixed at the bottom end of the feeding box 2 facing the main housing 1 of the wire marking machine. A bushing 8 is fitted on the connecting shaft 7. The bushing 8 is fixed below the feed inlet of the main housing 1 of the wire marking machine. An ear block 20 that is bolted to the main housing 1 of the wire marking machine is also provided on the outer wall of the bushing 8.

[0019] In a further embodiment, the bottom of the feed box 2 facing the main housing 1 of the wire marking machine has a second opening 9, and the middle of the feed box 2 away from the main housing 1 of the wire marking machine has a first opening 3. A first guide wheel 11 is rotatably mounted inside the feed box 2 near the first opening 3. A pair of first guide wheels 11 are arranged side-by-side. A pair of second guide wheels 12 are rotatably mounted inside the feed box 2 near the second opening 9. The pair of second guide wheels 12 are perpendicular to the pair of first guide wheels 11. A pressure wheel 13 is provided above the pair of first guide wheels 11. A support member 14 for elastically pressing down on the pressure wheel 13 is provided at the top of the feed box 2. The pipeline passes sequentially through the first opening 3, between the pressure roller 13 and a pair of first guide rollers 11, and between a pair of second guide rollers 12. Then, it exits the feed box 2 through the second opening 9 and enters the feed port of the main housing 1 of the wire marking machine. During the printing process of the pipeline by the wire marking machine, the support member 14 pushes the pressure roller 13 to press down with elastic force. The pipeline is tightened between the pressure roller 13 and the pair of first guide rollers 11. With the help of the pair of second guide rollers 12, the pipeline is guided, so that the pipeline enters the main housing 1 of the wire marking machine in a smooth and extended state for printing. This ensures both the printing effect and the smoothness of the pipeline printing, effectively solving the problem of feed jamming caused by pipeline twisting and bending.

[0020] In this embodiment, the support member 14 includes a fixed tube 16 vertically mounted on the top wall of the feed box 2, a connecting rod 18 movably passing through the bottom end of the fixed tube 16, and a spring 17 mounted inside the fixed tube 16. One end of the connecting rod 18 extending into the fixed tube 16 is connected to a stop block 19. A pressure wheel 13 is mounted on the bottom end of the connecting rod 18. The spring 17 pushes the connecting rod 18 to press the pressure wheel 13 down. The top surface of the fixed tube 16 is through-hole, and the top end of the fixed tube 16 is threadedly connected to the top wall of the feed box 2, which facilitates assembly.

[0021] In this embodiment, a cover plate 4 is provided on the side of the feed box 2. The top of the cover plate 4 is hinged to the feed box 2. A handle 5 is provided at the bottom of the cover plate 4 to facilitate the operation of threading the pipeline. An iron sheet 6 is embedded at the bottom of the cover plate 4. A magnetic post 15 is provided at the bottom of the feed box 2 corresponding to the position of the iron sheet 6 to magnetically close the cover plate 4.

[0022] In a further embodiment, an end block 10 is provided at the end of the connecting shaft 7, and the bushing 8 is rotatably sleeved with the end block 10, thereby the bushing 8 and the connecting shaft 7 are rotatably engaged. A tightening bolt 21 that can abut against the end block 10 is threaded through the side wall of the bushing 8. After loosening the tightening bolt 21, the feed box 2 can be rotated down to be level with the main housing 1 of the wire marking machine, thereby realizing the folding of the feed box 2, reducing the footprint, and making it convenient to carry and store.

[0023] Working principle: During pipeline printing, the feed box 2 is rotated to a vertical position, and then the clamping bolt 21 is tightened to abut against the end block 10. The connecting shaft 7 and the feed box 2 are rotated and positioned. The cover plate 4 is opened, and the pipeline to be printed is passed sequentially through the first opening 3, between the pressure roller 13 and a pair of first guide rollers 11, and between a pair of second guide rollers 12. Then, it passes out of the feed box 2 through the second opening 9 and into the feed port of the main housing 1 of the wire marking machine. During the pipeline printing process of the wire marking machine, the spring 17 pushes the connecting rod 18 to press down the pressure roller 13, and the pipeline... The pressure roller 13 is tightened between the pressure roller 13 and a pair of first guide rollers 11, and a pair of second guide rollers 12 are used to guide the pipeline, so that the pipeline enters the main housing 1 of the wire marking machine in a smooth and extended state for printing. This ensures both the printing effect and the smoothness of the pipeline printing, effectively solving the problem of feeding jam caused by pipeline twisting and bending. After the pipeline printing is completed, the clamping bolt 21 is loosened, and the feed box 2 can be rotated down to be level with the main housing 1 of the wire marking machine, so as to realize the folding of the feed box 2, reduce the footprint, and facilitate carrying and storage.

[0024] All technical features in this embodiment can be freely combined according to actual needs.
