[0002] A spraying machine is a special painting device that uses spraying technology. Its principle is to control the air flow to instantaneously push the air distribution reversing device to reverse, so that the piston of the pneumatic motor makes a stable and continuous reciprocating motion, pressurizes the inhaled paint, transports the paint to the spray gun of the spraying machine through a high-pressure hose, and the paint is instantaneously atomized by the spray gun and then released onto the surface of the object to be painted. The spraying machine mainly consists of a feeding device, a spray gun, and an atomization generating structure.

[0003] Compared with the actual use process, among the existing workpiece surface spraying devices, one device that uses electrostatic spraying technology has the problem that since the paint is in powder form, it is very easy for the operator to inhale it during the spraying process.

[0021] The following further elaborates on this application in conjunction with the attached drawings. Figures 1 - 3 A further detailed description of this application will be given below.

[0022] Embodiment 1

[0023] Referring to Figures 1 - 3 , a workpiece surface spraying device includes a support frame 1. On one side of the bottom end of the support frame 1, there is a water tank 2. On the outer side of one end of the water tank 2, a transmission rail 3 is welded. At the bottom of the outer side of one end of the transmission rail 3, a transmission motor 4 is installed through a base. On the outer side of one end of the transmission rail 3, a transmission screw 5 is rotatably connected through a bracket. A sliding seat 6 is slidably embedded inside the transmission rail 3. One end of the sliding seat 6 is sleeved outside the transmission screw 5 through a threaded sleeve. One end of the transmission screw 5 is connected to the transmission end of the transmission motor 4. At the top of the transmission rail 3, an air pump 7 is installed. The air outlet end of the air pump 7 is connected to a hose 9. The air outlet end of the hose 9 is connected to the air inlet end of a spraying body 8. The air inlet end of the air pump 7 is connected to the air outlet end of an external paint pipe. One end of the sliding seat 6 is fixed with a spraying body 8 through a bolt. In order to enable the spraying mechanism to adjust its height, so that the spraying process is more comprehensive;

[0024] On the outer side of one end of the water tank 2, a water pump 10 is installed through a base. The water outlet end of the water pump 10 is connected to a water filling box 11. The water outlet end of the water filling box 11 is connected to four dispersion pipes 12. A shut-off valve 13 is installed in the middle section of several dispersion pipes 12. In the middle of the top end of the support frame 1, four spraying boxes 14 are installed. The water outlet ends of the four dispersion pipes 12 all penetrate the support frame 1 and are respectively connected to the four spraying boxes 14. A number of spray heads 15 are installed at the bottom ends of several spraying boxes 14. The four spray heads 15 are directly above the water tank 2. In order to collect the excess paint generated during the spraying process through a circulating water curtain, thus ensuring the safety of the operator;

[0025] On the outer side of one end of the support frame 1, a feeding frame 16 is welded. On the outer side of one end of the feeding frame 16, a feeding conveyor motor 17 is installed through a base. Inside the feeding frame 16, a conveyor belt 18 is rotatably installed. A number of fixing bases 19 are installed on the outer side of the conveyor belt 18. Inside several fixing bases 19, hooks 20 are rotatably connected. Hook limiters 21 are installed on the outer side of several fixing bases 19. The water inlet end of the water pump 10 is connected to a filter box 22. The water inlet end of the filter box 22 penetrates and extends to the inside of the water tank 2. In order to make the feeding of the workpiece more convenient.

[0026] Working principle: First, the operator hangs the workpiece to be sprayed on the inner side of the hook 20, and rotates the surface to be sprayed to the spraying end of the spraying mechanism by rotating the hook 20 rotatably connected to the inner side of the fixed base 19. After all the hooks 20 are rotated, the operator tightens a number of hook limiters 21 to limit the position of the workpiece. Then, the operator selects the spraying position of the water curtain according to the longitudinal extension width of the workpiece. Four spraying boxes 14 are successively installed at the spraying end of the spraying mechanism along the top of the support frame 1. Select the spraying box 14 closest to the workpiece and not covering the workpiece. Then, the shut-off valve 13 installed at the terminal of the dispersion pipe 12 connected to the water inlet end of the spraying box 14 is opened to limit the stop of the other spraying boxes 14;

[0027] Then, the operator connects the air inlet end of the air pump 7 to the air inlet end of the external paint tank, and then starts the drive motor 4. At this time, the drive motor 4 will drive the conveyor belt 18 installed at its drive end through the bearing to rotate. At the same time, the conveyor belt 18 will drive the workpiece fixed by the hook 20 rotatably installed on the outer side through the inner side of the fixed base 19 to be conveyed. After the workpiece is conveyed to the spraying end of the spraying mechanism, the conveying is stopped. Then, the air pump 7 is started. At this time, the air pump 7 will pump the external paint to the air inlet end of the spraying body 8 and spray it out through the spraying body 8. During this period, the operator starts the drive motor 4. At this time, the drive motor 4 will drive the drive screw 5 connected to its drive end to drive, and the drive screw 5 will drive the sliding seat 6 sleeved on its outer side through the thread sleeve to move upward inside the drive rail 3. The sliding seat 6 will drive the spraying body 8 to move, so as to realize the full spraying from the bottom to the top of the workpiece surface. Before this, the operator needs to start the water pump 10. The water pump 10 will pump the water in the water tank 2 to the water filling box 11, and then the water filling box 11 will transport it to the inside of the dispersion pipe 12 with the shut-off valve 13 opened, and then the dispersion pipe 12 will transport it to the spraying box 14 connected to it. Finally, it is sprayed out through a number of nozzles 15 installed at the bottom of the spraying box 14 to form a water curtain, and the water curtain will fall into the water tank 2, thus realizing the recycling of water. The filter box 22 installed at the water inlet end of the water pump 10 can ensure that the paint is filtered during the water circulation, and the water curtain can collect the excess paint overflowing from the workpiece surface to prevent it from flying around randomly, thus ensuring the safety of the operator.

[0028] The above are all the preferred embodiments of this application, and do not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
