The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0028] According to an embodiment of the present invention, a spraying device that facilitates the replacement of spray heads is provided.

[0029] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-4As shown, a spraying device for easy replacement of spray heads according to an embodiment of the present invention includes a housing 1. A partition 7 is fixedly connected to the middle position inside the housing 1. Spraying pipes 13 are fixedly installed on the bottom surface of the partition 7 and on both sides of the inner wall of the housing 1. A first connecting pipe 18 is fixedly connected to the spraying pipe 13, and a nozzle 14 is provided on one side of the first connecting pipe 18. A second connecting pipe 22 is fixedly installed on the nozzle 14, and one end of the second connecting pipe 22 extends into the interior of the first connecting pipe 18. A mounting plate 12 is provided on one side surface of the housing 1, and the mounting plate 12... A pump body 11 is fixedly installed on the top surface. The pump body 11 is connected to the housing 1 via a suction pipe and to the spray pipe 13 via a delivery pipe. A bushing is provided at the middle position of the top surface of the housing 1, and a first rotating rod 4 passes through the bushing. A stirring blade 5 is fixedly installed on the first rotating rod 4 inside the housing 1. A bushing is provided at the middle position of the bottom surface of the housing 1, and a second rotating rod 10 passes through the bushing. A placement seat 9 is provided at the top of the second rotating rod 10 inside the housing 1. A dual-shaft motor 8 is fixedly installed at the middle position of one side surface of the housing 1. The output end of motor 8 and one end of the first rotating rod 4 and the second rotating rod 10 are fixedly connected to synchronous pulleys 3. A synchronous belt 6 is provided between the synchronous pulleys 3. When paint is added to the housing 1, the pump body 11 on one side of the mounting plate 12 is opened. The pump body 11 conveys the paint in the housing 1 to the spray pipe 13 through the suction pipe and the delivery pipe. The paint is then sprayed out through the nozzle 14 on the spray pipe 13, thus automatically spraying the workpiece on the placement seat 9. When the dual-axis motor 8 is turned on, the dual-axis motor 8 drives the synchronous pulleys 3 to rotate. The synchronous pulleys 3 rotate simultaneously with the synchronous belt 6. The use of synchronous belt 6 drives the first rotating rod 4 and the second rotating rod 10 to rotate, causing the stirring blade 5 on the first rotating rod 4 to rotate and stir the paint in the box 1. At the same time, the second rotating rod 10 drives the placement seat 9 to rotate, causing the workpiece on the placement seat 9 to rotate. This allows the paint to be sprayed evenly onto the workpiece, which helps to improve the uniformity of the spraying and facilitates automatic spraying of the workpiece. This not only improves the work efficiency but also reduces the adverse effects of exhaust gas during spraying on the workers and improves their safety.

[0030] In one embodiment, the outer surface of the second connecting pipe 22 is provided with an external thread 20, and the inner wall of the first connecting pipe 18 is provided with an internal thread 19. The external thread 20 and the internal thread 19 are threadedly connected. By rotating the nozzle 14, the external thread 19 on the outer surface of the second connecting pipe 22 on the nozzle 14 is moved away from the internal thread 20 on the inner wall of the first connecting pipe 18. When the second connecting pipe 22 is moved away from the first connecting pipe 18, the nozzle 14 can be removed from the spray pipe 13, reducing the limitations during use and thus improving its practicality.

[0031] In one embodiment, a plurality of spray pipes 13 are provided, and the plurality of spray pipes 13 are evenly distributed on both sides of the inner wall of the partition 7 and the housing 1. The use of spray pipes 13 and nozzles 14 can improve the uniformity of spraying on the workpiece.

[0032] In one embodiment, the outer surface of the nozzle 14 is provided with anti-slip blocks 21. There are multiple anti-slip blocks 21, and the multiple anti-slip blocks 21 are evenly distributed on the outer surface of the nozzle 14. The use of anti-slip blocks 21 can improve the anti-slip effect of the nozzle 14, thereby making it easier to remove the nozzle 14 from the first connecting pipe 18.

[0033] In one embodiment, a feed pipe 2 is provided on one side of the top surface of the housing 1, through which paint can be added to the housing 1.

[0034] In one embodiment, a drain pipe 16 is provided on one side surface of the housing 1 below the mounting plate 12, and a valve 15 is fixedly installed on the drain pipe 16. By opening the valve 15 on the drain pipe 16, the used paint at the bottom of the housing 1 can be discharged.

[0035] In one embodiment, the bottom surface of the box 1 is provided with support legs 24 on both sides, and a collection box 17 is provided on one side of the support legs 24, wherein excess paint can be collected by using the collection box 17.

[0036] In one embodiment, the front surface of the housing 1 is provided with a door 23, which is hinged to the housing 1 via a hinge. The workpiece can be picked up and put in by opening the door 23.

[0037] In one embodiment, the control switch control circuit can be implemented by simple programming by those skilled in the art, and is common knowledge in the field. It is only used and not modified, so the control method and circuit connection will not be described in detail.

[0038] Working principle: Paint is added to the housing 1. The pump 11 on one side of the mounting plate 12 is opened. The pump 11 conveys the paint in the housing 1 to the spray pipe 13 through the suction pipe and the delivery pipe. The paint is then sprayed out through the nozzle 14 on the spray pipe 13, automatically spraying the workpiece on the placement seat 9. By turning on the dual-axis motor 8, the synchronous pulley 3 is rotated. The synchronous pulley 3, through the use of the synchronous belt 6, drives the first rotating rod 4 and the second rotating rod 10 to rotate. This causes the stirring blade 5 on the first rotating rod 4 to rotate, which stirs the paint in the housing 1. The second rotating rod 10, while rotating, drives the placement seat... Rotating the nozzle 14 causes the workpiece on the placement seat 9 to rotate, which allows the paint to be sprayed evenly onto the workpiece, improving the uniformity of the spraying and facilitating automatic spraying. This not only improves work efficiency but also reduces the adverse effects of exhaust fumes on workers, enhancing safety. By rotating the nozzle 14, the external thread 19 on the outer surface of the second connecting pipe 22 on the nozzle 14 moves away from the internal thread 20 on the inner wall of the first connecting pipe 18. When the second connecting pipe 22 moves away from the first connecting pipe 18, the nozzle 14 can be removed from the spraying pipe 13, reducing limitations during use and improving its practicality.
