Description

Technical Field

[0001] This utility model belongs to the field of automotive plastic parts spraying technology, and in particular relates to an electrostatic spraying device for automotive plastic parts using water-based environmentally friendly paint. Background Technology

[0002] The electrostatic spraying device for water-based environmentally friendly paint on automotive plastic parts is an automated spraying system designed specifically for automotive plastic parts. It uses electrostatic adsorption technology to uniformly coat the plastic surface with water-based environmentally friendly paint, meeting the process requirements of high adhesion, low VOC emissions, and coverage of complex structures.

[0003] Traditionally, after painting automotive plastic parts, to avoid affecting the painting process when handling them, the plastic parts need to wait in the equipment for a period of time to allow the paint to dry before being removed or flipped for painting. This process consumes a lot of time, causing the equipment to run idle. This not only increases the energy consumption of the equipment, but also significantly reduces production efficiency. Therefore, we have proposed an electrostatic spraying device for automotive plastic parts using water-based environmentally friendly paint. Utility Model Content

[0004] The purpose of this invention is to provide an electrostatic spraying device for water-based environmentally friendly paint on automotive plastic parts. By setting up a switching section, specifically, after spraying, the unsprayed plastic parts are placed in the empty space on the switching plate, and then the switching plate is pushed to perform a switching process, moving the sprayed plastic parts to the outside of the spraying box for drying, thus facilitating removal or flipping. The unsprayed plastic parts then enter the spraying box for spraying, effectively improving production efficiency. This solves the problem that in existing automotive plastic parts, after spraying, the parts need to wait in the equipment for a period of time to avoid affecting the spraying process when removing them, which not only increases energy consumption but also significantly reduces production efficiency.

[0040] One specific application of this embodiment is:

[0041] In use, first connect the spraying delivery pipe to the delivery pipe 274 to deliver the paint to the diversion pipe 271. Then place the plastic part to be sprayed on the external shifting plate 31. Next, activate the two electric push rods 265, which drive the two baffles 261 upward through the fixing block 262, opening the spraying box 21. Then push the shifting plate 31 containing the plastic part into the spraying box 21, and the other part of the shifting plate 31 moves to the outside of the spraying box 21. When the shifting plate 31 moves, it will drive the bottom slider 32 to slide on the slide rail 321, and the connecting plate 322 will hold the positioning block 34. 2. Push and press to make the locking block 342 enter the slot 341 and squeeze the spring 343 so that the connecting plate 322 can be smoothly disengaged. When the slot 323 on the connecting plate 322 moves to the position of the locking block 342 on the other side, the locking block 342 will spring into the slot 323 under the elastic action of the spring 343, thereby positioning the connecting plate 322. Then the switching plate 31 is positioned. Then, the two electric push rods 265 are activated to drive the baffle 261 to move downward and seal the spray box 21. When the baffle 261 moves, it slides on the limiting strip 263, making the movement of the limiting strip 263 more stable.

[0042] After the spray box 21 is sealed, the paint is distributed through the diversion pipe 271 to several nozzles 272 and then sprayed out to coat the plastic parts. The nozzles 272 are high-speed rotary cup nozzles (speed 30,000~60,000 RPM) or bipolar electrostatic nozzles with atomized particle size of 40~60 μm; electrostatic parameters: voltage 60~90 kV (adapting to the high resistance characteristics of water-based paints), current 0.1~0.5 mA / cm², to prevent paint film breakdown; during the spraying process, the motor 224 is started to drive the threaded rod 222 to rotate, and the moving seat 221 will drive the diversion pipe 271 to move left or right through the connecting block 273, thereby uniformly spraying the plastic parts. During the movement, the conveying pipe 274 slides in the slide groove 25, which will not affect the pipeline to deliver the paint. The controller 23 is used to control the start and stop of the electric push rod 265, the motor 224 and the nozzles 272.

[0043] After the spraying is completed, the two electric push rods 265 are activated to move the two baffles 261 upward, opening the spraying box 21. Then, the unsprayed plastic parts are placed in the empty space on the switching plate 31, and the switching plate 31 is pushed to move the sprayed plastic parts to the outside of the spraying box 21. The unsprayed plastic parts then enter the spraying box 21, where they can be sprayed. The sprayed plastic parts can be dried outside, making them easy to remove or flip. This not only avoids affecting the spraying position but also allows the equipment to continuously perform spraying work, preventing the equipment from running idle and effectively improving production efficiency.
