[0002] Electrostatic spraying of water-based environmentally friendly paint is a solvent-free, low-pollution, energy-saving coating technology, which is mainly used in the coating process of water-based environmentally friendly paint. This technology uses an electrostatic field as a charge transfer method, so that the paint is sprayed onto the surface of the workpiece in the form of high-voltage electrostatic spray, thereby achieving efficient, uniform and consistent coating. Electrostatic spraying technology of water-based environmentally friendly paint has a wide range of applications, including furniture manufacturing, automobile repair, metal products and other industries.

[0003] The prior art publication number CN221157213U discloses an electrostatic spraying production line, which belongs to the field of electrostatic spraying processing equipment, including a support column, the bottom end of the support column is fixed to the ground by a fixing plate, there are two support columns and the lower surfaces of the top two ends are fixedly connected with guide rails, the guide rails are straight-edged elliptical, and a paint chain is slidably connected inside the guide rails, and a hook is fixed to the bottom of the paint chain through a locking assembly, and a paint room is arranged between the two support columns. The reciprocating screw rod drives the nozzle to spray the product up and down under the drive of the screw motor, which is beneficial to improve the overall spraying effect; the spring fixes the upper end of the pressing block inwardly through the contraction force, at this time, the pressing block fixes the plug column in the slot and completes the fixation of the hook, when the hook is removed for cleaning, the lower end of the pressing block is pressed downward, and at the same time, the upper end of the pressing block is tilted and the plug column is pulled out of the slot, at this time, the hook can be detached from the fixed seat, and the locking assembly has the effect of quickly and conveniently installing and removing the hook.

[0060] A groove 17 is provided on the column 16, and the electrostatic nozzle 15 is located on the inner side wall of the groove 17 and is fixedly connected to the inner side wall of the groove 17. A connecting column 18 is fixedly connected to the center of the lower end face of the column 16, and the lower end face of the connecting column 18 is fixedly connected to the output end of the motor 19, and the motor 19 is located inside the bottom plate 5. The connecting column 18 is respectively inserted through the T-shaped support plate 901, the bottom column 8, and the center of the large gear 7 is rotatably connected to each other. A filter box 20 is fixedly connected to the outer side of the column 16, and an air inlet 21 is provided on the front end face of the filter box 20.

[0061] The working principle of this embodiment is:

[0062] First, when the product enters the spray booth 2 with the start of the conveying mechanism 3 and stops at the groove 17 on the column 16, the motor 19 is turned on to drive the connecting column 18 to drive the column 16 to rotate as a whole, and the channel tube 14 is synchronously driven to move between the bottom column 8 and the T-shaped support plate 901, and the screw 12 is driven to drive the first pinion 11 to move, and the first pinion 11 is meshed with the tooth groove 10, and the first pinion 11 is relatively driven to drive the screw 12 to rotate;

[0063] Second, since the water-based environmentally friendly spray paint 26 is injected into the inner side of the second reserved groove 9, when the screw 12 rotates, the water-based environmentally friendly spray paint 26 is driven to rise along the thread through the thread on the screw 12, and enters the inner top of the channel tube 14 at the same time. As the water-based environmentally friendly spray paint 26 continues to enter, the pressure at the inner top of the channel tube 14 will become greater and greater. Then, by turning on the electrostatic spray head 15, the water-based environmentally friendly spray paint 26 is sprayed through the electrostatic spray head 15, so that 360-degree spraying of the product can be achieved;

[0064] Third, during the spraying process, if the spraying generates mist that is dispersed in the air, the filter box 20 is driven to move through the rotation of the column 16, and then the induced fan 22 is turned on to drive the air into the inside of the filter box 20 through the air inlet 21. At the same time, when the filter box 20 moves, it drives the connecting rod 23 to move, and moves between the first reserved groove 6 and the bottom column 8. At the same time, the connecting rod 23 drives the second pinion 25 to move, and the second pinion 25 moves along the outer tooth groove of the large gear 7, while relatively driving the second pinion 25 to rotate, and relatively driving the paint mist filter paper 24 to move through the connecting rod 23, and contacting the mist in the air entering the inner side of the filter box 20. At the same time, the air is filtered by the paint mist filter paper 24 that absorbs the paint mist.

[0065] The present invention provides a fully automatic water-based environmentally friendly paint electrostatic spraying production line through improvement. When spraying, the motor 19 is turned on to drive the column 16 to rotate, and the tooth groove 10 is meshed with the first pinion 11. The first pinion 11 moves along the tooth groove 10 and rotates. The water-based environmentally friendly spray paint 26 is driven to the top of the inner side of the channel tube 14 through the screw 12. At the same time, as the water-based environmentally friendly spray paint 26 continues to enter the channel tube 14, the pressure inside the channel tube 14 increases, and the electrostatic spray head 15 is turned on to spray the product. At the same time, when the column 16 rotates, it drives the electrostatic nozzle 15 to move and can also spray the product 360 degrees, which greatly reduces the situation of spray leakage. Synchronously, when the column 16 rotates, it can also drive the filter box 20 to move synchronously. The second small gear 25 moves along the outside of the large gear 7 while driving the second small gear 25 to rotate itself, and the paint mist filter paper 24 is driven to move through the connecting rod 23. The induced fan 22 is turned on to drive the outside air into the inside of the filter box 20 to contact the paint mist filter paper 24, so that filtering can be carried out, which is safer to use.
