Description

Technical Field

[0001] This utility model relates to the field of automotive technology, specifically to a fully enclosed powder coating device for automotive lighting aluminum profiles. Background Technology

[0002] Aluminum coating refers to the process of uniformly spraying paint onto the surface of aluminum materials using spraying equipment to form a protective or decorative layer. Spraying technology is widely used in the surface treatment of aluminum materials to improve their appearance, corrosion resistance, and service life. Aluminum coating primarily employs electrostatic powder coating technology. This technology utilizes the corona discharge phenomenon, charging plastic powder through high-voltage electrostatic equipment before spraying it onto the aluminum surface. Under the influence of the electric field, the powder coating is adsorbed onto the workpiece, forming a uniform coating. After high-temperature baking, the powder melts, flows, and solidifies, ultimately forming a hard coating film.

[0003] In response, Chinese patent application number CN222428327U discloses a fully enclosed powder coating device for aluminum profiles. This device includes a working chamber with a sealed door on its outer side. Inside the working chamber is a conveyor for transporting workpieces, and outside the conveyor is a transmission component for driving the conveyor. Inside the working chamber is a coating component for coating the workpieces. The conveyor includes a bracket fixed inside the working chamber, with a support cover fixedly connected to the outer side of the bracket. Inside the support cover is a conveyor belt, with a lifting ring fixedly connected to the outer side of the conveyor belt. The transmission component includes a motor fixedly connected to the outer side of the support cover. This fully enclosed powder coating device for aluminum profiles solves the problem of low coating efficiency in existing devices where workpieces are mounted on clamps and can only be coated once before the next workpiece is replaced.

[0004] However, existing fully enclosed powder coating equipment for automotive lighting aluminum profiles requires manual flipping of the profiles within the coating chamber before full coating can be performed, thus reducing the equipment's efficiency.

[0005] Therefore, in order to solve the above problems, a fully enclosed powder coating device for automotive lighting aluminum profiles is proposed. Summary of the Invention

[0006] The purpose of this utility model is to provide a fully enclosed powder coating device for automotive lighting aluminum profiles, in order to solve the problem mentioned in the background art of the prior art of fully enclosed powder coating devices for automotive lighting aluminum profiles. Because the existing coating devices require manual flipping of the automotive lighting aluminum profiles in the coating chamber before the full coating work can be carried out, the working efficiency of the device is reduced.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a fully enclosed powder coating device for automotive lighting aluminum profiles, comprising: a fixed box and an electrostatic powder coating machine. The electrostatic powder coating machine is provided on one side of the fixed box, and a control panel is provided on the electrostatic powder coating machine.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The device is equipped with a flipping mechanism that allows for the flipping of aluminum plates within a fixed box. The aluminum plates are supported by a limiting plate within the clamping assembly of the mechanism. Initial positioning is achieved via a sliding groove, followed by vertical positioning and support via a telescopic rod and spring through a clamping plate. The first servo motor then drives a rotating disk via a movable rod, which in turn drives a rotating rod, which in turn drives the limiting plate to rotate, thus flipping the aluminum plates within the fixed box and improving the device's working efficiency.

[0016] 2. The device is equipped with a spraying mechanism that allows for the spraying of aluminum plates. The control panel within the mechanism controls an electrostatic powder coating machine to produce the spraying material, which is then transported to the spraying assembly via connecting pipes and hoses. A second servo motor drives a transmission rod to rotate, which in turn moves the first sliding sleeve. During this process, the spraying assembly is limited by a crossbar between the sliding rod and the second sliding sleeve, allowing the assembly to move and spray the aluminum plate through the nozzle. The spraying effect can be observed through the transparent glass on the enclosure door. After spraying, harmful gases are expelled from the enclosure via an exhaust system, thus improving the device's practicality. Attached Figure Description
