[0012] As a further improvement, the inner ring has a plane aa perpendicular to its axial center line, the side of the inner ring fixing position is inclined relative to the plane aa, and the angle between the side of the inner ring fixing position and the plane aa is α, where α is 40° to 50°.

[0013] As a further improvement, the outer ring fixed connection position is arranged along the radial direction of the outer ring.

[0014] As a further improvement, the outer ring fixed connection positions are arranged in an array around the axial center of the outer ring.

[0015] This utility model also provides a fusion gun, including a nozzle and the aforementioned fusion gun powder feeding nozzle assembly, wherein the inner ring is mounted on the nozzle.

[0016] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0017] (1) The present invention provides a powder feeding nozzle assembly for a spray gun, comprising an outer ring and an inner ring, wherein a nozzle is also installed on the outer ring, the nozzle comprising a first nozzle and a second nozzle, thereby improving spraying efficiency.

[0030] like Figure 1-3 As shown, this embodiment provides a powder feeding nozzle assembly for a molten ladle, including an outer ring 1 and an inner ring 4. The outer ring 1 is sleeved on the outside of the inner ring 4, and the inner ring 4 is used to connect with the molten ladle. A nozzle 3 is also installed on the outer ring 1. The nozzle 3 includes a first nozzle and a second nozzle. The spraying direction of the first nozzle and the second nozzle is both towards the center of the outer ring 1, and the first nozzle and the second nozzle are located on the same plane and are symmetrically arranged.

[0031] The plasma spray gun uses plasma to melt materials such as ceramic powder and metal powder, forming a film on the product surface, which makes the product corrosion-resistant and extends its service life. In this solution, the plasma spray gun powder feeding nozzle assembly is installed on the nozzle of the plasma spray gun, which sprays a plasma flame. Nozzle 3 includes a first nozzle and a second nozzle, used to spray materials such as ceramic powder and metal powder. The plasma melts the ceramic powder and metal powder, forming a film on the product surface. This solution uses a first nozzle and a second nozzle to improve spraying efficiency. Furthermore, the first nozzle and the second nozzle are located on the same plane and symmetrically arranged, resulting in more uniform powder distribution.

[0032] As a further improvement, the spray directions of the first and second nozzles are perpendicular to the axial centerline of the outer ring 1. During the debugging process, it was found that when the spray directions of the first and second nozzles are set perpendicular to the axial centerline of the outer ring 1, the powder distribution uniformity is better.

[0033] like Figure 2 As shown, a first fixing bracket 21 and a second fixing bracket 22 are connected to the outer ring 1. The first nozzle is fixed to the first fixing bracket 21, and the second nozzle is fixed to the second fixing bracket 22. In this embodiment, the first fixing bracket 21 and the second fixing bracket 22 have the same structure, and the structure of the first fixing bracket 21 will be described. Specifically, the first fixing bracket 21 has a nozzle connection position 201 and a nozzle fixing position 202. The nozzle connection position 201 is a through hole for installing the nozzle. The nozzle fixing position 202 is also hole-shaped and is perpendicular to the nozzle connection position 201. During installation, the first nozzle is installed in the nozzle connection position 201, and screws or bolts can be installed in the nozzle fixing position 202 for tightening, thus fixing the first nozzle in the nozzle connection position 201. The second fixing bracket 22 and the second nozzle are set up in the same way.

[0034] Combination Figure 1 and Figure 3 As shown, in this embodiment, the outer ring 1 and the inner ring 4 are detachably connected. Specifically, an inner ring fixing position 42 is recessed along the circumference of the outer side of the inner ring 4, and an outer ring fixing connection position 11 is provided on the outer ring 1. A connector is installed in the outer ring fixing connection position 11, and the connector is pressed against the inner ring fixing position 42. The inner ring fixing position 42 is a groove, the outer ring fixing connection position 11 is a through hole, and the connector is a screw or other component. The outer ring 1 is sleeved on the outside of the inner ring 4. The positions of the inner ring fixing position 42 and the outer ring fixing connection position 11 are adjusted to correspond, and the connector is installed in the outer ring fixing connection position 11 and tightened so that the connector is pressed against the bottom of the groove of the inner ring fixing position 42. In addition, the inner ring 4 can be made of copper to give it better conductivity and prevent the inner ring 4 from being burned by discharge.

[0035] like Figure 3As shown, as a further improvement, the inner ring 4 has a plane aa perpendicular to its axial center line. The side of the inner ring fixing position 42 is inclined relative to the plane aa, and the angle between the side of the inner ring fixing position 42 and the plane aa is α, where α is 40° to 50°. Preferably, α is 45°, which makes the shape of the inner ring fixing position 42 more compatible with the shape of the connector, increases the contact area between the inner ring fixing position 42 and the connector, and makes the connection between the outer ring 1 and the inner ring 4 more secure after the connector is tightened.

[0036] like Figure 2 As shown, the outer ring fixing connection 11 is arranged along the radial direction of the outer ring 1, so that the connector presses the inner ring 4 to the maximum extent. In addition, the outer ring fixing connection 11 is arranged in an array around the axial center of the outer ring 1, so that the inner ring 4 is subjected to uniform force.

[0037] It should be noted that in other embodiments, the outer ring 1 and the inner ring 4 are integrally formed. For example, the outer ring 1 and the inner ring 4 are integrally formed by molding.

[0038] In this embodiment, the powder feeding nozzle assembly of the spray gun includes a first nozzle and a second nozzle, thereby improving spraying efficiency. Furthermore, the outer ring 1 and the inner ring 4 are detachably connected. First, the inner ring 4 is connected to the nozzle of the spray gun, and then the outer ring 1 is connected. Since the first and second nozzles are mounted on the outer ring 1, and the inner ring fixing position 42 is a recess along the outer circumference of the inner ring 4, the outer ring 1 can rotate at any angle around the axial center of the inner ring 4, allowing for convenient adjustment of the positions of the first and second nozzles.

[0039] This application also provides a fusion gun, including a nozzle and the aforementioned fusion gun powder feeding nozzle assembly, with an inner ring 4 mounted on the nozzle.
