Description

Technical Field

[0001] This utility model relates to the field of welding wire production technology, specifically to a device for applying powder to the surface of stainless steel welding wire. Background Technology

[0002] During the production process, welding powder needs to be coated on the surface of the welding wire to improve its heat resistance and other properties. In the process of coating welding wire with powder, powder coating equipment is often used to process the welding wire.

[0003] Referring to the existing Chinese patent publication number CN215587032U, a powder coating device for solid stainless steel welding wire is disclosed, including a working box and a collecting box. The top of the working box is open and has a removable box cover. The side wall of the working box has an inlet and an outlet for the welding wire to pass through. The collecting box is located on the side of the welding wire outlet and is used to collect welding powder. The lower part of the working box has a discharge port connected to the collecting box. The collecting box also has a box door. Inside the working box, from top to bottom, there are a powder hopper and a support bracket for supporting the welding wire. A support frame is fixed on the inner side wall of the working box. The powder hopper is mounted on the support frame. The support frame has a vibration mechanism for making the powder hopper vibrate. The bottom of the powder hopper has several through holes. The support bracket has several powder leakage holes. The welding powder coating mechanism is provided at the welding wire outlet of the working box.

[0004] The aforementioned stainless steel solid welding wire surface powdering device can effectively achieve uniform powder application and improve the powdering effect. However, this device still has some drawbacks, such as: the fixed brush structure makes it difficult to adjust the gap between the brush and the welding wire when dealing with stainless steel welding wires of different diameters. This can easily lead to uneven powder application, either because the gap is too small, obstructing the wire's movement, or because the gap is too large, resulting in insufficient powder application and failing to meet process requirements.

[0005] The purpose of this invention is to provide a powder coating device for stainless steel welding wire to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0008] The processing box has an inlet and an outlet at both ends, two movable plates connected to the processing box via an adjustment mechanism, and a controller installed on the processing box.

[0009] The adjustment mechanism includes a fixed plate, a drive assembly, a bidirectional threaded rod, and a limiting rod. The fixed plate is fixedly installed in the inner cavity of the processing box. The limiting rod is fixedly connected between the fixed plates.

[0010] Two powder brushes are engaged at one end of the two movable plates via a locking mechanism, and several powder spraying heads are installed at the other end of the movable plates. The powder spraying heads are connected to a powder spraying assembly.

[0011] Preferably, an upper baffle and a lower baffle are installed at the feed inlet and the discharge outlet, and grooves are formed on the upper baffle and the lower baffle.

[0012] Preferably, the drive assembly includes a servo motor, a pulley, and a transmission belt. The pulley is connected to the extension end of the bidirectional threaded rod that passes through the fixed plate.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This invention, through the adjustment mechanism, allows for adjustment of the distance between the powder-applying brushes and the nozzle. When processing welding wires with smaller diameters, the distance between the brushes and nozzles can be reduced, allowing the brushes to adhere more closely to the wire surface and the nozzles to more accurately apply powder. For welding wires with larger diameters, the spacing can be appropriately increased to ensure smooth passage and uniform powder coverage. This flexible adjustment function effectively solves the problem of uneven powder application in traditional devices when dealing with welding wires of different diameters, significantly improving the uniformity and quality of powder application. This, in turn, enhances the overall production process and product quality of stainless steel welding wire, providing a strong guarantee for the efficient and stable operation of the production process.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0026] Please see Figures 1-5 This utility model provides a technical solution:

[0027] A device for applying powder to the surface of stainless steel welding wire, comprising:

[0028] The processing box 1 has an inlet 2 and an outlet 3 at both ends. An upper baffle 11 and a lower baffle 12 are installed at the inlet 2 and the outlet 3, respectively. Grooves 13 are provided on the upper baffle 11 and the lower baffle 12. Two movable plates 4 are connected to the processing box 1 through an adjustment mechanism. The upper baffle 11 and the lower baffle 12 can reduce the amount of powder that floats out from the inlet 2 and the outlet 3, thereby reducing environmental pollution.

[0029] The adjustment mechanism includes a fixed plate 5, a drive assembly, a bidirectional threaded rod 6, and a limiting rod 7. The fixed plate 5 is fixedly installed in the inner cavity of the processing box 1. The limiting rod 7 is fixedly connected between the fixed plates 5. The bidirectional threaded rod 6 is rotatably connected to the fixed plate 5. The drive assembly is connected to the bidirectional threaded rod 6. The bidirectional threaded rod 6 is threadedly connected to the moving plate 4. The moving plate 4 has a through hole 8, and the limiting rod 7 passes through the through hole 8.

[0030] Furthermore, the drive assembly includes a servo motor 14, a pulley 15, and a drive belt 16. The pulley 15 is connected to the extension end of the bidirectional threaded rod 6 that passes through the fixed plate 5. The servo motor 14 is fixedly installed in the inner cavity of the processing box 1, and the output end of the servo motor 14 is connected to one of the pulleys 15.

[0031] Before starting the powder coating operation, the controller 32 sends a command to the servo motor 14 according to the diameter of the welding wire to be treated. Upon receiving the electrical signal, the servo motor 14 starts, and its output drives the connected pulley 15 to rotate. Since the pulleys 15 are connected by a transmission belt 16, they drive the two bidirectional threaded rods 6 to rotate synchronously. The two bidirectional threaded rods 6 are rotatably connected to the fixed plate 5, and the moving plate 4 is threaded to both ends of the two bidirectional threaded rods 6. The moving plate 4 has through holes 8 for the limiting rods 7 to pass through. Under the limiting and guiding action of the limiting rods 7, the two moving plates 4 move linearly in opposite directions or away from each other as the bidirectional threaded rods 6 rotate. This flexible adjustment function effectively solves the problem of uneven powder coating when dealing with welding wires of different diameters using traditional devices, significantly improving the uniformity and quality of powder coating, thereby enhancing the overall production process level and product quality of stainless steel welding wire, and providing a strong guarantee for the efficient and stable operation of the production process.

[0032] Two movable plates 4 are engaged at one end by a locking mechanism for two powder brushes 9. The locking mechanism includes a locking plate 17, two locking blocks 18 and a return spring 19. The locking plate 17 is fixedly mounted on the movable plate 4. A connecting groove 20 is provided on the locking plate 17. The powder brush 9 is engaged in the connecting groove 20. An installation groove 21 is provided on the powder brush 9. The locking blocks 18 are slidably connected in the installation groove 21. A locking groove 22 is provided on the locking plate 17 for the locking blocks 18 to pass through the installation groove 21 and engage. The two ends of the return spring 19 are connected to the locking blocks 18.

[0033] When disassembling the powder brush 9, press the locking block 18 to squeeze the return spring 19, press the locking block 18 out of the locking groove 22, and then pull the powder brush 9 out of the connecting groove 20.

[0034] When installing the plaster brush 9, the plaster brush 9 is engaged in the connecting groove 20. Press the engaging block 18 and push the plaster brush 9 at the same time. When the plaster brush 9 is fully engaged in the connecting groove 20, the return spring 19 releases its elastic potential energy and pushes the engaging block 18 to engage in the engaging groove 22, thus engaging the plaster brush 9 with the engaging plate 17.

[0035] Several powder spraying heads 10 are installed at the other end of the movable plate 4. The powder spraying heads 10 are connected to a powder spraying assembly. The powder spraying assembly includes a powder spraying machine 23, a connecting pipe 24, a telescopic pipe 25, and a powder spraying pipe 26. The powder spraying machine 23 is fixedly installed at one end of the processing box 1. The powder spraying heads 10 are connected to the powder spraying pipe 26. The two ends of the telescopic pipe 25 are connected to the powder spraying pipe 26 and the connecting pipe 24, respectively. The other end of the connecting pipe 24 is connected to the powder spraying machine 23.

[0036] Once the welding wire enters the processing box 1 and the spacing of the moving plate 4 is adjusted, the controller 32 starts the powder spraying machine 23. The high-pressure airflow generated by the powder spraying machine 23 carries the powder and enters the telescopic tube 25 through the connecting pipe 24. The telescopic tube 25, with its telescopic characteristics, can adapt to the position changes of the moving plate 4, ensuring smooth powder transmission. Finally, the powder reaches the powder spraying head 10 through the powder spraying pipe 26. The powder spraying head 10 sprays the powder evenly onto the surface of the welding wire. The powder can cover welding wires of different diameters in an all-round and uniform manner, which can effectively improve the powder coating quality of the welding wire surface.

[0037] Based on the above embodiment, the processing box 1 is provided with an inspection hole 27, and an inspection door 29 is installed at the inspection hole 27 by mounting bolts 28. A dust collection drawer 30 is installed at the lower end of the processing box 1, and a handle 31 is installed on the dust collection drawer 30.

[0038] When inspecting the inside of the processing box 1, remove the mounting bolts 28 and then remove the inspection door 29.

[0039] The dust collection drawer 30 can collect excess powder, and the handle 31 makes it easy to remove the dust collection drawer 30.

[0040] In the above embodiment, a controller 32 is installed on the processing box 1, and the controller 32 is electrically connected to the servo motor 14 and the powder sprayer 23.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
