Description

Technical Field

[0001] This utility model relates to the field of automotive seat parts processing technology, specifically a surface spraying device for precision machining of upper belt plates. Background Technology

[0002] In the manufacturing process of automotive seats, the upper panel is a key component, and the quality of its surface coating directly affects the seat's aesthetics, durability, and safety. Traditional surface coating equipment has many drawbacks when applied to the processing of automotive seat upper panels.

[0003] On the one hand, traditional spraying equipment suffers from poor paint uniformity. Its spraying mechanism is poorly designed, and the nozzle distribution and angle settings cannot meet the spraying requirements of the complex surface of the upper conveyor belt. This easily leads to localized areas of excessively thick or thin paint, affecting not only the appearance but also potentially reducing the protective performance of the upper conveyor belt due to uneven coating thickness. On the other hand, the lack of effective auxiliary support structures during the spraying process causes the upper conveyor belt to wobble due to its own deformation or external forces, resulting in spraying position deviation, reduced spraying accuracy, and impacting the subsequent assembly quality of the automotive seats.

[0004] Furthermore, the existing paint curing methods in spraying equipment are relatively outdated, mostly relying on natural air drying or ordinary baking, resulting in low curing efficiency and easy contamination with dust and other impurities during the curing process, affecting coating quality. Simultaneously, the height adjustment of the spraying mechanism is inconvenient, making it difficult to adapt to the spraying needs of upper plates of different sizes, resulting in poor equipment versatility. Moreover, the paint guide hose is prone to bending and tangling during use, affecting the stability and continuity of paint delivery, leading to spraying interruptions and reduced production efficiency. Therefore, a surface spraying device for precision machining of upper plates is proposed to solve the aforementioned problems. Utility Model Content

It solves the problems of uneven paint spraying, unstable upper belt plate conveying, low curing efficiency, poor equipment versatility, and discontinuous paint conveying in traditional spraying devices.

[0012] This surface spraying device for precision machining of upper strip plates has the advantages of uniform spraying, accurate positioning, efficient curing, and convenient operation.

[0013] Based on the above technical solution, the present invention can be further improved as follows.

[0043] Working principle:

[0044] Step 1: Place the upper panel of the car seat to be painted onto the feed belt 1. The feed belt 1 carries the upper panel through the feed port 7 into the paint spray box 2. During this process, the auxiliary wheel 303 of the auxiliary mechanism 3, under the action of the spring 304 and the telescopic rod 301, is tightly attached to the bottom of the feed belt 1, providing stable support for the feed belt 1 and preventing it from shaking or shifting during the conveying process.

[0045] Step 2: According to the specifications of the upper belt plate, loosen the fastening nut 504 of the fixing mechanism 5, adjust the position of the slide rod 501 in the slide groove 502, adjust the painting mechanism 4 to a suitable height, and then tighten the fastening nut 504 to fix it. The paint enters the main pipe 401 through the paint guide hose 403 and the connecting valve head 402, and then is diverted through the diversion pipe 404. The high-pressure atomizing nozzle 405 atomizes the paint and sprays it evenly on the surface of the upper belt plate.

[0046] Step 3: After the first layer of paint is sprayed by the high-pressure atomizing nozzle 405 on the left, it continues to move forward under the drive of the feeding belt 1 and enters the area below the light curing mechanism 6. The baking lamp 603 emits high-intensity light to light-cur the initial layer of paint sprayed on the surface of the upper belt plate. The light-shielding soft plate 604 and the counterweight block 605 prevent light leakage. After the paint has completed the initial curing, the high-pressure atomizing nozzle 405 on the right performs a second spraying. Then the upper belt plate leaves the paint spraying box 2 through the feed port 7 and is transported to the baking box in the production line for complete baking curing.
