Description

Technical Field

[0001] The utility model relates to the technical field of thermal spraying, and more specifically, to a thermal spraying device with controllable spraying distance and spraying angle. Background Art

[0002] Thermal spraying is to heat and melt the coating material, atomize it into extremely fine particles with a high-speed airflow, and spray it onto the surface of the workpiece at a very high speed to form a coating. Different coating materials are selected according to needs to obtain one or more properties such as wear resistance, corrosion resistance, oxidation resistance, and heat resistance. In the process of parts processing and production, thermal spraying equipment is needed for thermal spraying operations.

[0003] However, existing thermal spraying devices are unable to grasp the specific values ​​of spraying, so during the spraying process, the operator is completely dependent on adjusting the angle and distance for spraying. This will result in poor spraying accuracy and is not conducive to accurate spraying operations.

[0004] For example, a Chinese patent with authorization announcement number CN217164980U discloses a thermal spraying device with controllable spraying distance and spraying angle. The structure can be precisely adjusted according to the specific adjustment value. The linkage rotating rod drives the angle pointer to rotate, so that the angle pointer can indicate on the angle dial, so that it can be adjusted to the specified numerical angle for spraying operation. In this way, when adjusting, the precise value can be grasped to adjust the angle and distance, so that the spraying accuracy is higher.

[0005] However, when this structure is actually used, it is difficult to cool the surface of the spray pipe after spraying is completed. Since the spray pipe needs to transport high-temperature thermal spray paint, these temperatures will cause the temperature of the spray pipe surface to continue to rise. If it is not cooled, it will not only affect the service life of the spray pipe, but also easily lead to safety accidents. In view of this, the utility model proposes a thermal spraying device with controllable spraying distance and spraying angle. Utility Model Content

[0024] In a specific embodiment, as shown in the attached Figure 1 、 3 As shown in Figures 4 and 5, a cooling structure for cooling the spray pipe 3 is provided on the outside of the spray pipe 3. The cooling structure includes a cooling pipe 6. The cooling pipe 6 is sleeved on the outside of the spray pipe 3.

The connecting hose 4 extends to the inside of the cooling pipe 6 through the second through hole 8, and the connecting hose 4 is connected to the spray pipe 3.

A condensation circulation hose 14 is provided on the back of the cooling tube 6 and on the side away from the condensation delivery hose 13. The input end of the circulating pump 12 extends to the interior of the cooling box 11, and the output end of the circulating pump 12 is connected to the condensation delivery hose 13. One end of the condensation delivery hose 13 is connected to the cooling tube 6, one end of the condensation circulation hose 14 is connected to the cooling tube 6, and the other end thereof extends to the interior of the cooling box 11.

[0025] Specifically, in this structure, in the process of spraying high-temperature paint, in order to avoid the high temperature affecting the service life of the spray pipe 3, after the spraying is completed, the circulation pump 12 transports the cooling liquid inside the cooling box 11 to the inside of the cooling pipe 6 through the condensation delivery hose 13. The cooling liquid circulates through the cooling pipe 6 and flows back to the cooling box 11 through the condensation circulation hose 14.

[0026] During the circulation of the cooling liquid inside the cooling pipe 6, the multiple heat-conducting rings 10 outside the spray pipe 3 transfer heat to the surface of the spray pipe 3 and cool the heat through the transported cooling liquid, thereby achieving the purpose of cooling the spray pipe 3 and avoiding the continuous high temperature on the surface of the spray pipe 3, which not only causes safety accidents but also affects the service life of the spray pipe 3.

[0027] When the structure is in operation as a whole, first, multiple atomizing nozzles 5 extend to the interior of the cooling pipe 6 through the first through hole 7 and are connected to the spray pipe 3, and the connecting hose 4 extends to the interior of the cooling pipe 6 through the second through hole 8, and the connecting hose 4 is connected to the spray pipe 3. At the same time, sealing covers 9 are installed at the first through hole 7 and the second through hole 8, which not only does not affect the transportation and spraying of the high-temperature spray liquid, but also can avoid leakage of the cooling liquid during the transportation process.

[0028] In a specific embodiment, as shown in the attached Figure 1 、 2 As shown, the outer walls of the two support seats 2 are each provided with a mounting groove 15, a screw rod 16 is provided inside one of the mounting grooves 15, and a slide rod 17 is provided inside the other mounting groove 15, and a mounting seat 18 and a guide seat 19 are respectively provided outside the screw rod 16 and the slide rod 17, and a first motor 20 is provided at one end of the screw rod 16, and the output end of the first motor 20 is coaxially connected to the screw rod 16 inside one of the mounting grooves 15, and the mounting seat 18 and the guide seat 19 are respectively threadedly connected and slidably connected to the outside of the screw rod 16 and the slide rod 17.

[0029] Specifically, in this structure, the first motor 20 drives the screw 16 inside one of the mounting slots 15 to rotate, so that the mounting seat 18 moves and drives the spray pipe 3 to move. At the same time, the guide seat 19 slides and guides on the outside of the slide rod 17, thereby adjusting the distance between the spray pipe 3 and the workpiece being sprayed, thereby achieving control of the spraying distance.

[0030] In a specific embodiment, as shown in the attached Figure 2 As shown, a second motor 21 is provided on the surface of the mounting seat 18, and a mounting plate 22 is provided at the output end of the second motor 21. The mounting plate 22 is connected to one end of the spray pipe 3, and the guide seat 19 is rotatably connected to the other end of the nozzle pipe.

[0031] Specifically, in this structure, the second motor 21 on the mounting seat 18 can drive the mounting plate 22 to rotate, and drive one end of the spray pipe 3 to rotate, and the other end of the spray pipe 3 rotates at the outer wall of the guide seat 19. The rotating spray pipe 3 can drive multiple atomizing nozzles 5 to adjust the angle, thereby adjusting the spraying angle.

[0032] Working principle of this utility model:

[0033] When the above structure is used, the workpiece to be sprayed is first fixed by a bracket or a clamp. It is necessary to ensure that the workpiece to be sprayed is at the same height as the spray pipe 3. The connecting hose 4 is connected to the thermal spray machine. The thermal spray machine is an existing product and will not be described in detail. The spray material is transported to the interior of the spray pipe 3 through the connecting hose 4 and finally sprayed out through multiple atomizing nozzles 5 to achieve a thermal spraying effect on the workpiece.

[0034] When the spraying distance needs to be adjusted, the first motor 20 drives the screw 16 inside one of the mounting slots 15 to rotate, so that the mounting seat 18 moves, and drives the spray pipe 3 to move, and at the same time, the guide seat 19 slides and guides on the outside of the slide rod 17, thereby adjusting the distance between the spray pipe 3 and the workpiece being sprayed, thereby achieving control of the spraying distance;

[0035] When adjusting the spraying angle, the second motor 21 on the mounting seat 18 can drive the mounting plate 22 to rotate, and drive one end of the spraying pipe 3 to rotate, and the other end of the spraying pipe 3 rotates at the outer wall of the guide seat 19. The rotating spraying pipe 3 can drive the multiple atomizing nozzles 5 to adjust the angle, thereby adjusting the spraying angle;

[0036] After spraying is completed, in order to prevent the surface of the spray pipe 3 from being continuously heated to affect the service life of the spray pipe 3 and to prevent the high temperature of the spray pipe 3 from causing a safety accident, the cooling liquid in the cooling box 11 is transported to the inside of the cooling pipe 6 through the condensation transport hose 13 by using the circulation pump 12. The cooling liquid circulates through the cooling pipe 6 and flows back to the cooling box 11 through the condensation circulation hose 14.

[0037] During the circulation of the cooling liquid inside the cooling pipe 6, the multiple heat-conducting rings 10 outside the spray pipe 3 transfer heat to the surface of the spray pipe 3 and cool the heat through the transported cooling liquid, thereby achieving the purpose of cooling the spray pipe 3 and avoiding the continuous high temperature on the surface of the spray pipe 3, which not only causes safety accidents but also affects the service life of the spray pipe 3.

[0038] It is worth noting that the condensation conveying hose 13 installed outside the cooling pipe 6 and the condensation conveying hose 13 have a certain length and will not affect the distance adjustment and angle adjustment of the spray pipe 3.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
