Referring to fig. 1, the muzzle of the electrostatic powder coating machine with two guns according to the present invention has a first extension end 1 and a second extension end 2. The first extending end 1 and the second extending end 2 are both conical cylinders, and the bottom of the first extending end 1 and the bottom of the second extending end 2 are connected with the muzzle in a seamless mode. The center lines of the first extending end 1 and the second extending end 2 are parallel to the center line of the muzzle.
The top end of the first extending end 1 is provided with a first powder spraying port 1-1.
The top of the second extending end 2 is rotatably provided with a spray ball 3, the spray ball 3 is provided with a spray hole 3-1 and a check hole 3-2 which are opposite, and a channel for communicating the spray hole 3-1 and the check hole 3-2 is arranged in the spray ball 3 along the radial direction. In the rotating process of the spray ball 3, the spray hole 3-1 is always positioned outside the second extending end, and the inlet hole 3-2 is always positioned inside the second extending end.
Therefore, the powder attached with static electricity in the muzzle is sprayed out through the spray hole 3-1, and the extension direction of the channel in the spray ball can be adjusted by rotating the spray ball 3, so that the spray direction of the spray hole is adjusted, and directional powder spraying is realized. In the embodiment, the powder spraying direction can be adjusted by finely adjusting the powder spraying ball, and the flexibility is high.
In this embodiment, the channel formed in the spray ball 3 is tapered, and the top end thereof communicates with the spray hole and the bottom end thereof communicates with the inlet hole. Therefore, the inner diameter of the channel is gradually reduced from one end of the inlet hole to one end of the spray hole, so that the air pressure in the channel is favorably ensured, and the powder spraying range of the spray hole 3-1 is ensured. In order to further ensure the range distance of the powder spraying, in the specific implementation, the aperture of the inlet hole 3-2 is at least three times of that of the spray hole 3-1.
Spout 3 surfaces of ball and be equipped with the curved surface chamber, the curved surface intracavity is installed and is turned to ball 4, and the centre of sphere that turns to ball 4 holds in the curved surface intracavity.

The first connecting rod 7 is arranged on the gun body through a supporting frame 8.
Therefore, when the first connecting rod 7 horizontally slides on the supporting frame 8, the spraying ball 3 can be driven to horizontally rotate by the second connecting rod 6 and the steering ball. At this time, the steering ball firstly buffers the sliding motion of the first connecting rod 7, and then transmits the buffered sliding motion to the jet ball 3, so that the jet hole 3-1 horizontally rotates under the condition that the position of the center of the jet ball 3 is not changed.
The second connecting rod 6 can drive the spray ball to vertically rotate through the steering ball. Specifically, when the first end of the second connecting rod 6 rotates, the change of the relative position of the second connecting rod 6 in the vertical direction is buffered through the pivoting of the second connecting rod 6 and the third connecting rod 5, the steering ball 4 also buffers the change of the vertical position and then transmits the buffered change of the vertical position to the spray ball 3, so that the spray ball 3 vertically rotates, and the spray hole vertically rotates under the condition that the position of the center of the spray ball is not changed.
In this embodiment, the horizontal sliding of the first link 7 and the vertical rotation of the second link 6 are weakened by the steering ball, and the fine adjustment of the position and orientation of the nozzle hole 3-1 is achieved.

Thus, the stability of the gun body A is ensured, and the stability of powder spraying is realized; the flexible control of the powder spraying direction is ensured by finely adjusting the powder spraying ball 3. And the spraying ball is automatically controlled by the driving mechanism, so that the objectivity of fine adjustment is ensured. In specific implementation, the driving mechanism is installed on the supporting frame 8.
The support frame 8 includes a horizontal rail 81, a main strut 82, and an auxiliary strut 83. The horizontal rail 81 is horizontally mounted on the gun body a by a main strut 82. The auxiliary strut 83 is connected to the body a at one end and abuts against the main strut 82 at the other end. The horizontal rail 81 ensures the stability of the horizontal sliding of the first connecting rod 7. The stability of the support frame 8 is further ensured by the arrangement of the auxiliary supporting rod, so that the working reliability of the spray ball 3 is improved.

In the second state, the rotary baffle 9 blocks the second extension end 2, and the first extension end 1 is communicated with the muzzle. Specifically, the driving mechanism is also connected with the rotary baffle plate to control the rotary baffle plate to switch between the first state and the second state.
When the double-gun electrostatic powder spraying machine is used for electrostatic powder spraying, whether the first powder spraying port 1-1 or the spraying hole is applicable is determined. For example, if the worker holds the powder spraying device by hand, the first powder spraying port 1-1 can be selected, and at this time, the rotary baffle 9 can be driven to execute the second state; if the gun body is fixed for powder spraying, spray holes can be selected for realizing the adjustment of the powder spraying direction, and at the moment, after the rotary baffle is driven to execute the first state, the spray holes 3-1 are adjusted by driving the first connecting rod and the second connecting rod 6.
In specific implementation, the aperture of the spray hole 3-1 can be smaller than that of the first powder spraying port 1-1, so that the first powder spraying port 1-1 can be selected when large-range powder spraying is carried out; when the powder is sprayed with precision, a spray hole can be selected.
Specifically, in the present embodiment, a sealing plate is disposed at the muzzle, the first extending end 1 and the second extending end 2 are both mounted on the sealing plate, and through holes are respectively disposed on the sealing plate corresponding to the first extending end 1 and the second extending end 2.
