[0040] S1: The operator places the paint production equipment parts in the area surrounded by the limit rods, and then changes the height of the lifting plate driven by the lifting component, and then transports the paint production equipment parts to the transmission unit through the set handling component;

[0041] S2: When the paint production equipment parts are located on the transmission unit, as the transmission unit works, the position of the paint production equipment parts on the transmission unit is adjusted, and then the spray equipment cleans them, and then the paint production equipment parts are moved into the coating room, and then the adjustment unit starts to work;

[0043] S4: When coating, a certain pressure of gas is injected into the air inlet nozzle, and the gas flows out of the nozzle along the air inlet cavity, so that the gas contacts with the parts of the coating production equipment, and then the residual liquid on the parts of the coating production equipment is dried, and then the corresponding coating liquid is injected into the coating part, so that the coating liquid can be mixed in the mixing cavity and sprayed out from the nozzle along the discharge pipe, and then the coating liquid and the gas can be mixed, so that the surface of the parts of the coating production equipment can be coated, and the coating work of the parts of the coating production equipment is completed. At the same time, after the coating work is completed, the gas pressure and temperature of the gas sprayed from the nozzle are changed to solidify the coating liquid coated on the surface of the parts of the coating production equipment;

[0044] S5: During the operation of the spraying equipment, the generated wastewater falls into the bottom of the collection chamber and enters the inner cylinder along the water inlet pipe, and the air flow can be discharged from the water outlet pipe through the sieve holes arranged on the inner cylinder, and the impurity residues larger than the diameter of the sieve holes are transported to the waste discharge pipe along with the rotating inner cylinder and discharged from the waste discharge pipe;

[0046] Beneficial effect: The present invention discloses an automated coating device and method for paint production equipment. Through the coating unit provided, when it is necessary to coat the parts of the paint production equipment, high-pressure gas with temperature can be introduced into the air inlet nozzle in advance, and the gas enters the air outlet cavity along the air inlet cavity and is sprayed out from the nozzle, thereby drying the surface of the parts and blowing away some attached dust and impurities, thereby completing the drying and secondary cleaning functions of the parts of the paint production equipment. Then, the coating liquid enters the nozzle seat from the feed nozzle, and at this time, the coating liquid enters the mixing cavity along the coating cavity. Since the feed end of the discharge pipe is located at a predetermined height at the bottom of the mixing cavity, the coating liquid can be introduced into the area between the feed end of the discharge pipe and the bottom of the mixing cavity, thereby increasing the injection speed of the coating liquid. When the coating liquid height in the mixing cavity is higher than the feed end of the discharge pipe, the coating liquid can flow into the second limiting cavity along the discharge pipe. The coating liquid is then ejected from the second limiting ball and then discharged from the discharge channel in the second limiting ball. Since there is a predetermined distance between the discharge pipe and the inner wall of the nozzle's air outlet, and the discharge channel is V-shaped, before the coating liquid moves away from the second limiting ball, after the coating liquid collides with the second limiting ball, the coating liquid leaving the second limiting ball collides with the air wall formed by the high-pressure gas, thereby forming smaller droplets that can be coated on the parts. After the coating work is completed, the injection of coating liquid into the feed nozzle can be stopped, and the gas pressure at the air inlet nozzle can be lowered, thereby completing the solidification of the coating liquid on the surface of the parts. The device integrates the drying equipment with the coating equipment, thereby completing the drying of residual water droplets without the need for a separate drying chamber, and at the same time, there is a matching relationship between the air inlet part and the coating part, so that the coating can be smoothly coated on the parts for the coating production equipment, thereby completing the coating work on the parts for the coating production equipment.

[0073] Working principle description: when it is necessary to coat the parts in the coating production equipment, the lifting motor 221 starts to work, and the moving lifting motor 221 drives the driving wheel connected to it to rotate, and then cooperates with the driving wheel on the lifting screw rod 223 through the provided driving belt, thereby driving the lifting screw rod 223 to rotate, and the rotating screw rod can drive the driving block 224 to move, thereby adjusting the height of the lifting plate 225. When it is at a predetermined height, the transport component 23 starts to work, and then the lifting plate 225 can be grasped and transported, so that it can be located on the transmission unit 3, and then with the cooperation of the transmission unit 3, the parts can be moved. The parts are located in the predetermined spraying area; when the parts are located in the spraying area, the spraying device 4 starts to work, and then the parts can be cleaned. At this time, the cleaning motor starts to work, and the gear on the brush roller 33 can be driven to rotate through the set chain, thereby driving the brush roller 33 to rotate, and the parts located between the first roller conveyor 31 and the second roller conveyor 32 are brushed to complete the cleaning of the parts; then, with the movement of the transmission unit 3, the parts can be moved into the coating chamber 8, and firstly, the air pump is used to rush the high-pressure gas with temperature into the air inlet nozzle 731 on the nozzle seat 71, and after the high-pressure gas with temperature is introduced, the gas flows along the air inlet cavity 7 34 enters the air outlet chamber 735 and is sprayed out from the nozzle 72, thereby drying the surface of the parts and blowing away some attached dust and impurities, and then the coating liquid enters the nozzle seat 71 from the feed nozzle 741. At this time, the coating liquid enters the mixing chamber 743 along the coating chamber 742. Since the feed end of the discharge pipe 744 is located at a predetermined height at the bottom of the mixing chamber 743, the coating liquid can be preliminarily mixed in the area between the feed end of the discharge pipe 744 and the bottom of the mixing chamber 743, or the same coating liquid can be introduced to increase the injection speed of the coating liquid. When the coating liquid height in the mixing chamber 743 is higher than the feed end of the discharge pipe 744, the coating liquid can flow along the discharge pipe 744. The material pipe 744 flows into the second limiting ball 747 and is discharged from the discharge channel in the second limiting ball 747. Since there is a predetermined distance between the discharge pipe 744 and the inner wall of the air outlet of the nozzle 72, and the discharge channel is V-shaped, before the coating liquid leaves the second limiting ball 747, after the coating liquid collides with the second limiting ball 747, the coating liquid leaving the second limiting ball 747 collides with the gas wall formed by the high-pressure gas, thereby forming smaller droplets to be coated on the parts. After the coating work is completed, the coating liquid can be stopped from being injected into the feed nozzle 741, and the gas pressure at the air inlet nozzle 731 can be lowered, thereby completing the solidification of the coating liquid on the surface of the parts.During the operation of the coating unit 7, the displacement assembly 52 also starts to work. At this time, the moving displacement motor 521 can drive the displacement screw 522 to rotate, and the moving displacement screw 522 can drive the connecting piece 523 to start moving. With the cooperation of the slider 525, the connecting piece 523 can be displaced in the length direction of the slide rail 524, thereby changing the position of the displacement block 526 on the coating rack 51, thereby changing the coating area of ​​the coating unit 7; then the rotating motor 532 starts to work, and the moving rotating motor 532 can drive the connecting block 533 connected thereto to move, and then drive another connecting block 533 to move through the set cross shaft 534, thereby adjusting the coating angle of the coating unit 7, and completing the adjustment of the coating area and coating angle of the coating unit 7 through cooperation with the displacement assembly 52; completing the adjustment of the surface of the parts After the curing of the surface coating liquid, the parts can move to the predetermined area with the cooperation of the transmission unit 3, and then the unloading of the parts is completed with the cooperation of another transport unit 2, and the cleaning and coating of the parts for the coating production equipment are completed; during the cleaning process, the cleaned wastewater and impurities pass through the collection chamber 9 from the water inlet pipe 62 into the inner cylinder 66, and then the rotating motor 64 starts to work, and the moving rotating motor 64 can drive the rotating shaft 65 to rotate, and then the moving rotating shaft 65 can drive the inner cylinder 66 to rotate, and the water in the wastewater entering the inner cylinder 66 enters the outlet pipe 68 through the sieve holes on the inner cylinder 66, and the impurities larger than the diameter of the sieve holes rotate with the inner cylinder 66 driving the guide bar 67, so that the impurities can move in the inner cylinder 66, and then be discharged from the waste discharge pipe 69, completing the collection of the residues attached to the parts. ;
