[0021] It should be noted here that: during the thermal spraying process, through the mutual cooperation of the transmission component and the adjustment component, each group of arc plates 201 moves closer to or away from each other. Through the movement of each group of arc plates 201, the discharge diameter of the discharge pipe is adjusted. Through the adjustment of the discharge diameter, the purpose of adjusting the spraying flow rate is achieved, ensuring the spraying effect and quality of the thermal spraying device. And during the entire flow rate adjustment process, only the driving ring 601 needs to be rotationally driven, without the need to replace and use nozzles of different models.

[0022] The transmission assembly includes an annular plate 401 sleeved and fixed on the outer side of the conveying pipe 102. A transmission ring 402 is arranged on the outer side of the annular plate 401. The transmission ring 402 is slidably connected to the outer side of the annular plate 401 through a sliding assembly. A connecting rod 403 is arranged between the transmission ring 402 and the arc-shaped plate 201.

[0023] It should be noted here that: during the movement of the transmission ring 402, through the sliding guiding action of the sliding assembly, the stressed transmission ring 402 moves along the axial direction of the annular plate 401. During the movement of the transmission ring 402, through the connection and transmission of the connecting rod 403, each group of arc-shaped plates 201 on the discharge pipe is pulled, so that each group of arc-shaped plates 201 move closer to or away from each other. Through the movement of each group of arc-shaped plates 201, the discharge diameter of the discharge pipe is adjusted.

[0024] The moving assembly includes a driving ring 601 sleeved on the outer side of the annular plate 401. The inner side of the driving ring 601 is in threaded engagement with the outer side of the annular plate 401. One side of the driving ring 601 is connected and transmitted with the transmission ring 402 through a connecting assembly. A plurality of anti-slip grooves 602 are formed on the outer side of the driving ring 601;

[0025] It should be noted here that: when the driving ring 601 is rotated, during the rotation of the driving ring 601, through the meshing transmission between the inner side of the driving ring 601 and the outer side of the annular plate 401, the driving ring 601 moves on the outer side of the annular plate 401;

[0026] It is worth noting here that: through the anti-slip grooves 602, the anti-slip effect during the rotation of the driving ring 601 is increased.

[0027] The connecting assembly includes an annular groove 701 formed on one side of the transmission ring 402. A connecting ring 702 is rotatably connected to the inner side of the annular groove 701. One side of the connecting ring 702 is fixed to one side of the driving ring 601. The cross-sections of the annular groove 701 and the connecting ring 702 are T-shaped. The transmission ring 402, the driving ring 601, the annular groove 701 and the connecting ring 702 are concentrically arranged;

[0028] It should be noted here that: during the movement of the driving ring 601, through the connection and transmission action of the annular groove 701 and the connecting ring 702, the transmission ring 402 is driven to move under force, and through the annular groove 701 and the connecting ring 702, the rotatable connection between the driving ring 601 and the transmission ring 402 is facilitated.

[0029] The flexible member includes an annular rubber ring 3 fixed to the front side of the annular plate 401, and the ends of the arc-shaped plate 201 and the rubber plate 202 are fixed to the front side of the annular rubber ring 3;

[0030] It should be noted here that: through the annular rubber ring 3, the arc-shaped plate 201 and the rubber plate 202 are flexibly connected, which is convenient for the arc-shaped plate 201 to perform adjustment movement after being stressed, and through the flexible connection effect, relative sealing is maintained during the adjustment process to avoid material leakage.

[0031] The sliding assembly includes a plurality of groups of sliding grooves 501 opened on the outer side of the annular plate 401. A slider 502 is slidably connected to the sliding grooves 501, and the slider 502 is fixed to the inner side of the transmission ring 402;

[0032] It should be noted here that: through the plurality of groups of sliding grooves 501 and the sliders 502, sliding guidance is provided for the transmission ring 402 after being stressed.

[0033] Working principle: During the use of the thermal spraying equipment, under the driving action of the delivery pump 103, the thermal spraying material inside the thermal spraying machine 101 is sprayed to a specified position through the delivery pipe 102 and the discharge pipe;

[0034] During the thermal spraying process, when it is necessary to adjust the spraying flow rate, the driving ring 601 is rotated. During the rotation of the driving ring 601, through the meshing transmission between the inner side of the driving ring 601 and the outer side of the annular plate 401, the driving ring 601 moves on the outer side of the annular plate 401. During the movement of the driving ring 601, through the connection and transmission action of the annular groove 701 and the connecting ring 702, the transmission ring 402 is driven to move under stress;

[0035] During the movement of the transmission ring 402, through the sliding guidance of the sliding assembly, the stressed transmission ring 402 moves along the axial direction of the annular plate 401. During the movement of the transmission ring 402, through the connection and transmission of the connecting rod 403, each group of arc-shaped plates 201 on the discharge pipe is pulled, so that each group of arc-shaped plates 201 move closer to or away from each other. Through the movement of each group of arc-shaped plates 201, the discharge diameter of the discharge pipe is adjusted. By adjusting the discharge diameter, the purpose of adjusting the spraying flow rate is achieved, ensuring the spraying effect and quality of the thermal spraying equipment. And during the entire flow rate adjustment process, only the driving ring 601 needs to be rotated and driven, without the need to replace different types of nozzles. This is convenient for the continuous use of the thermal spraying equipment during the flow rate adjustment process, and there is no need to repeatedly install and replace different nozzles, ensuring the convenient flow rate adjustment of the thermal spraying equipment.
