Description

Technical Field

[0001] This utility model relates to the field of metal-ceramic coating spraying technology, and more specifically, to a metal-ceramic coating spraying device. Background Technology

[0002] Metal-ceramic coating spraying equipment is a specialized equipment system that sprays metal-ceramic composite materials at high speed onto the surface of a workpiece in a molten or semi-molten state to form a high-performance coating. It is a complete integrated device including spray guns, powder feeding system, cooling system, control system, power system, etc. To ensure strength and cooling, existing equipment typically uses large and bulky spray guns, making it difficult to spray deep holes, narrow grooves, or areas with very complex structures with small inner diameters on the workpiece. This results in spray dead zones, and the flying powder and harmful exhaust gases generated during the spraying process pollute the environment and affect the health of operators. Based on this, this utility model discloses a metal-ceramic coating spraying device. Utility Model Content

[0003] To address the problems raised in the background art, existing spray guns, designed for strength and cooling, are typically bulky and heavy, making it difficult to spray deep holes, narrow grooves, or structurally complex areas of workpieces with small inner diameters, resulting in spray dead zones. Furthermore, the spraying process generates drifting powder and harmful exhaust gases, polluting the environment and affecting the health of operators. This invention provides a metal-ceramic coating spraying device, comprising a spray pipe with a feeding chamber inside. An angle adjustment assembly is mounted on the spray pipe, including a rotating chamber. The discharge end of the feeding chamber also has a rotating chamber. A rotating ball is rotatably installed inside the rotating cavity. A receiving cavity is opened inside the rotating ball, and the receiving cavity communicates with the feeding cavity through a receiving port. A nozzle is welded to the end of the rotating ball away from the receiving port. A fixed support rod is fixedly connected to the rotating ball near the nozzle. A connecting ring is connected to the end of the fixed support rod. A telescopic rod is installed on the connecting ring. A support block is fixedly connected to the outside of the nozzle near the rotating ball, and a fixed ring is fixedly connected to the end of the support block. A rotating ring is sleeved on the outside of the fixed ring. The telescopic rod is connected to one end of the telescopic rod through a connecting buckle. A protective component is installed on the connecting ring.

[0004] The connecting ring has a rolling cavity inside, and a rotating bead is provided inside the rolling cavity. The rotating bead is connected to the end of the telescopic rod through a connecting buckle.

[0005] The fixed ring has a limiting cavity inside, and a limiting annular block is set inside the limiting cavity. The block body of the limiting annular block passes through the opening of the limiting cavity and is connected to the inner arc surface of the rotating ring. A gear tooth is fixedly connected to one side of the block body of the limiting annular block. A drive motor is installed on the vertical surface of the fixed ring away from the connecting ring. The output shaft end of the drive motor is inserted into the limiting cavity and a gear is installed thereon. The gear meshes with the gear tooth.

[0006] When the telescopic rod is shortened to its shortest distance, the receiving port of the rotating ball is still located inside the rotating cavity.

[0007] The protective assembly includes a protective cover, which is fixed on the vertical surface of the connecting ring away from the fixed ring. An annular tube is connected to the plate end face of the protective cover away from the connecting ring, and an air extraction nozzle is installed around the annular tube with the working port of the air extraction nozzle facing the working port of the nozzle.

[0008] A connecting pipe is installed on the annular tube, and an air pump is installed on the connecting pipe. The protective cover is horn-shaped and constricts from the nozzle to the rotating ball.

[0009] Compared with existing technologies, the beneficial effects of this utility model are: 1. In this metal-ceramic coating spraying device, the size of the spray gun is reduced by the cooperation of the angle adjustment component, and the angle of the spray gun can be adjusted to achieve spraying of deep holes, narrow grooves or areas with very complex structures with small inner diameters of the workpiece, thus avoiding the existence of spraying dead angles.

[0010] 2. In this metal-ceramic coating spraying device, the protective components work together to extract and collect airborne powder and harmful gases during the spraying process, thereby avoiding environmental pollution and protecting the health of operators. Attached Figure Description

[0013] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0014] Therefore, this utility model provides a metal-ceramic coating spraying device, see [link to relevant documentation]. Figure 1 - Figure 5 As shown, it includes a nozzle 1, a feeding chamber 2 inside the nozzle 1, an angle adjustment assembly installed on the nozzle 1, the angle adjustment assembly including a rotating chamber 3, a rotating chamber 3 at the discharge end of the feeding chamber 2, a rotating ball 4 rotatably installed inside the rotating chamber 3, a receiving chamber inside the rotating ball 4, and the receiving chamber communicating with the feeding chamber 2 through a receiving port, a nozzle 5 welded to the end of the rotating ball 4 away from the receiving port, a fixed support rod 6 fixedly connected to the rotating ball 4 near the nozzle 5, a connecting ring 7 connected to the end of the fixed support rod 6, a telescopic rod 8 installed on the connecting ring 7, a support block fixedly connected to the outside of the nozzle 1 near the rotating ball 4, and a fixed ring 9 fixedly connected to the end of the support block, a rotating ring 10 sleeved on the outside of the fixed ring 9, and a connecting buckle connecting one end of the telescopic rod 8, and a protective assembly installed on the connecting ring 7. The fixed support rod 6 allows the rotating ball 4 and the nozzle 5 to rotate synchronously with the connecting ring 7, preventing the connecting ring 7 from rubbing against the spraying surface when adjusting the working angle of the nozzle 5.

[0015] The connecting ring 7 has a rolling cavity 11 inside, and a rotating bead 12 is installed inside the rolling cavity 11. The rotating bead 12 is connected to the end of the telescopic rod 8 through a connecting buckle. The rotating bead 12 can slide inside the rolling cavity 11 with the telescopic rod 8, thereby adjusting the working angle of the connecting ring 7 and thus adjusting the working angle of the nozzle 5.

[0016] A limiting cavity 13 is formed inside the fixed ring 9. A limiting annular block 14 is set inside the limiting cavity 13. The block body of the limiting annular block 14 passes through the opening of the limiting cavity 13 and connects to the inner arc surface of the rotating ring 10. A gear tooth 15 is fixedly connected to one side of the limiting annular block 14. A drive motor 16 is installed on the vertical surface of the fixed ring 9 away from the connecting ring 7. The output shaft end of the drive motor 16 is inserted into the limiting cavity 13 and a gear 17 is installed thereon. The gear 17 meshes with the gear tooth 15. By starting the drive motor 16, the gear 17 rotates. With the cooperation of the gear tooth 15, the limiting annular block 14 drives the rotating ring 10 and the telescopic rod 8 to move, thereby adjusting the working position of the rotating ball 12 and providing driving force for the rotation of the rotating ball 4, the nozzle 5, and the connecting ring 7.

[0017] When the telescopic rod 8 is shortened to its shortest distance, the receiving port of the rotating ball 4 is still located inside the rotating cavity 3.

[0018] During operation, the angle adjustment component's structural design allows for spraying of complex areas. Based on the spraying location and angle, the drive motor 16 is activated, causing the gear 17 to rotate. With the cooperation of the gear teeth 15, the limiting ring block 14 drives the rotating ring 10 to rotate within the limiting cavity 13. The telescopic rod 8 drives the rotating ball 12 to rotate within the rolling cavity 11. After the telescopic rod 8 drives the rotating ball 12 to a suitable position within the connecting ring 7, the telescopic rod 8 retracts. With the cooperation of the fixed support rod 6 and the connecting ring 7, the rotating ball 4 rotates along the rotating cavity 3, adjusting the spraying angle of the nozzle 5. This ensures that the smaller working end of the nozzle 5 faces the spraying location, enabling spraying of deep holes, narrow grooves, or highly complex areas with small inner diameters, avoiding spraying dead angles.

[0019] Further, see Figure 1 - Figure 2 , Figure 4 As shown, the protective assembly includes a protective cover 18. The protective cover 18 is fixed on the vertical surface of the connecting ring 7 away from the fixing ring 9. An annular tube 19 is connected to the plate end face of the protective cover 18 away from the connecting ring 7. An air extraction nozzle 20 is installed around the annular tube 19, and the working port of the air extraction nozzle 20 faces the working port of the nozzle 5.

[0020] A connecting pipe 21 is installed on the annular pipe 19, and a vacuum pump 22 is installed on the connecting pipe 21. The protective cover 18 is horn-shaped and is in a converging shape from the nozzle 5 to the rotating ball 4.

[0021] During operation, the protective components are designed to prevent the generation of paint dust and harmful gases during the spraying process. The vacuum pump 22 can be activated, and the working end of the vacuum nozzle 20 will generate suction. The dust and harmful gases will enter the interior of the annular pipe 19 through the vacuum nozzle 20 and be extracted into the collection device through the connecting pipe 21. This achieves the extraction and collection of airborne powder and harmful gases during the spraying process, avoiding environmental pollution and protecting the health of operators.

[0022] In summary, this effectively solves the problem that existing devices, in order to ensure strength and cooling, usually make the spray guns bulky and heavy, making it difficult to spray deep holes, narrow grooves or areas with very complex structures with small inner diameters on the workpiece, resulting in spraying dead corners. In addition, the flying powder and harmful exhaust gas generated during the spraying process will pollute the environment and affect the health of operators.
