Technical Field

[0002] Plasma cladding technology is a new type of surface modification technology that has been developed based on the improvement of argon arc welding machines. In the process of forming a plasma flame, argon gas needs to be input. Argon gas undergoes ionization reaction under the action of high-intensity current to produce a high-temperature and high-intensity plasma beam flame. Under the action of the high-temperature plasma beam, the alloy powder and the surface of the workpiece substrate are rapidly heated and melted, mixed, diffused, reacted, and solidified together. The plasma cladding spray gun head is mainly composed of the following parts: welding wire feed pipe, electrode and nozzle. The nozzle is one of the key parts of the plasma cladding spray gun. Its function is to control the discharge direction of the plasma arc, help solidify the molten material, and determine the type of welding and working performance. Most nozzles are made of ceramics, chromium alloys and other materials to ensure their stability and life under high temperature conditions.

[0003] At present, most plasma cladding spray guns are thermal reactions. In their working process, the alloy powder is mainly melted by heating. The nozzle moves along the set trajectory, and the molten material is extruded from the nozzle. The material solidifies quickly after being sprayed out and bonds with the surrounding materials. However, in the actual spraying process, material accumulation is likely to occur at the nozzle, forming redundant working nodules. Under high temperature conditions, the nozzle may be burned to produce ashes. The existing automatic cleaning device does not clean thoroughly enough. Manual cleaning with a blade may damage the nozzle. In addition, manual operation is cumbersome and the efficiency of the nozzle is greatly reduced. Summary of the invention

The first pulley 8 is fixedly connected to the output end of the driving motor 2, the second pulley 10 is fixedly connected to one end of the transmission shaft 11 facing the driving motor 2, the first pulley 8 is connected to the second pulley 10 through a belt 9, the transmission shaft 11 is rotatably connected to the fixed plate 21, the fixed plate 21 is fixedly connected to the top of the base plate 1, the rotating block 12 is fixedly connected to one end of the transmission shaft 11 close to the nozzle 3, the sleeve clamp 13 is fixedly connected to the outer wall of the rotating block 12, the sleeve clamp 13 is arranged on the circular edge of the rotating block 12, the bolt 14 is slidably connected to the sleeve clamp 13, and the nut 15 is threadedly connected to the bolt 14.

[0018] It should be noted that the specific models and specifications of the drive motor 2 and the water pump 6 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the field, so it is not repeated here.

[0019] Among them, the upper part is the power part in the rotating structure, which drives the first pulley 8 to rotate through the driving motor 2, and the first pulley 8 drives the second pulley 10 to rotate through the belt 9, thereby providing rotational power to the transmission shaft 11 and the nozzle 3.

[0020] The transmission shaft 11 penetrates through the outer wall of the fixed plate 21 and is rotatably connected. The upper part is a transmission part. The rotation of the second pulley 10 drives the transmission shaft 11 and the rotating block 12 to rotate.

[0021] The bolt 14 penetrates through the outer wall of the sleeve clamp 13 and is slidably connected, and the diameter of the nut 15 is larger than the diameter of the through hole on the outer wall of the sleeve clamp 13 .

[0022] Furthermore, the cleaning structure includes a water pipe 16, a diverter 17, evenly distributed flow tubes 18, a support column 19, and bristles 20.

[0023] Among them, the cleaning structure mainly uses the water pump 6 to draw the cleaning liquid through the diverter 17 and transport it to the flow tube 18, and finally overflows from the inside of the brush plate 7. While the brush plate 7 cleans the nozzle 3, the cleaning liquid is automatically discharged to reduce manpower consumption and can also be recycled.

[0024] Furthermore, the top end of the water pipe 16 is fixedly connected to the diverter 17 , the other end of the flow pipe 18 passes through the outer wall of the water pumping box 5 and is connected to the diverter 17 , and the other end of the support column 19 is fixedly connected to the outer wall of the brush plate 7 .

[0025] The nozzle 3 should be matched with the position of the bristles 20 inside the brush plate 7, and the position can be adjusted manually, so that the cleaning of the nozzle 3 is simpler and more comprehensive.

[0026] Working principle: first, place the nozzle 3 in the clamp 13, adjust the position of the nozzle 3 and clamp it by bringing the nut 15 and the bolt 14 close to each other, then start the drive motor 2, the drive motor 2 drives the first pulley 8 to rotate, the first pulley 8 drives the second pulley 10 to rotate through the belt 9, the second pulley 10 drives the transmission shaft 11 to rotate, the transmission shaft 11 drives the rotating block 12 to rotate, the rotating block 12 drives the clamp 13 and the nozzle 3 above to rotate, the nozzle 3 contacts the bristles 20 on the brush plate 7 and cleans through friction.

[0027] In order to increase the cleaning effect, the water pump 6 can be started. The water pump 6 draws the cleaning liquid inside the water tank 4 through the water pipe 6 into the diverter 17 and disperses it into the flow tube 18. The cleaning liquid flows out through the brush plate 7 to wet and clean the nozzle 3. Therefore, multiple rotational frictions enhance the cleaning force of the nozzle, making the cleaning effect more significant. In addition, the nozzle is easy to disassemble and the use is automatic throughout the process, which frees up manpower, makes the operation simpler, and greatly improves the efficiency of the nozzle.
