Description

An electrostatic dust removal device for an automotive trim painting line Technical Field

[0001] This utility model relates to the field of automotive trim parts production technology, and in particular to an electrostatic dust removal device for an automotive trim parts spraying line. Background Technology

[0002] Automotive trim parts refer to components installed inside and outside automobiles to beautify, protect, and enhance vehicle functionality. These include interior trim parts (such as dashboards, door panels, and seat trim) and exterior trim parts (such as grilles, bumpers, and body strips). They not only affect the car's appearance and texture but also serve functions such as dustproofing, waterproofing, and noise reduction. Using electrostatic dust removal equipment on a painting line can effectively remove dust, particles, and static electricity from the surface of trim parts, ensuring a clean surface before painting and avoiding problems such as particles, bubbles, or uneven coating during the painting process, thus improving painting quality. It also enhances coating adhesion, preventing coating peeling or blistering and extending service life. Furthermore, electrostatic dust removal equipment reduces painting defects and rework, lowering scrap rates and material waste, saving costs. A clean surface and uniform coating enhance the appearance and texture of trim parts, meeting high-quality requirements. Electrostatic dust removal equipment also reduces dust and pollutant emissions, meeting environmental protection requirements and reducing energy consumption. In summary, electrostatic dust removal equipment on painting lines improves the production efficiency and product quality of automotive trim parts through advantages such as improved painting quality, enhanced adhesion, reduced rework, and cost savings, while also meeting environmental protection requirements.

[0003] Existing electrostatic dust removal devices in automotive trim painting lines typically employ a single-angle electrostatic eliminator design for dust removal. Due to the complex shapes and uneven surfaces of trim parts, a single-angle electrostatic eliminator cannot evenly cover the entire surface, and some areas may fail to effectively remove static electricity and dust. This not only affects surface cleanliness before painting but may also lead to problems such as uneven coating, particle residue, or insufficient adhesion during the painting process, reducing painting quality and product yield. Therefore, this paper proposes an electrostatic dust removal device for automotive trim painting lines to address these issues. Summary of the Invention

[0004] To overcome the above shortcomings, this utility model provides an electrostatic dust removal device for automotive trim painting lines, aiming to improve the existing dust removal technology, which has a relatively simple dust removal structure and limited functions, and cannot achieve efficient dust removal.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an electrostatic dust removal device for an automotive trim spraying line, comprising a support frame, a spraying transmission line installed above the support frame, a support cover fixedly connected to the upper surface of the support frame, a dust removal component installed on one side inside the support cover, and a filter component installed on the upper surface of the support cover;

[0006] The dust removal assembly includes a support plate and an ion bar. The two ends of the ion bar are fixedly connected to the inner wall of the support plate. A hydraulic rod is fixedly connected to the upper surface of the support cover. The output end of the hydraulic rod is fixedly connected to the upper surface of the support plate. A limit rod is fixedly connected to one side of the outer wall of the support plate. A hinge seat is rotatably connected to one side of the inner wall of the support cover. A bracket is fixedly connected to one side of the hinge seat. An ion bar is fixedly connected to the inner wall of the bracket.

[0007] Furthermore, the filter assembly includes a support shell and a filter plate. The lower surface of the support shell is fixedly connected to the upper surface of the support cover. The outer wall of the filter plate is slidably connected to the inside of the support shell. A fan is installed through the inside of the support shell. A dust cover is installed on the outer wall of the fan. Fans are installed through the inside of the support cover on both sides. A dust cover is installed on the outer wall of the fan.

[0008] Furthermore, a collection hopper is fixedly connected to the lower surface of the support frame, and a collection box is fixedly connected to the lower surface of the collection hopper.

[0009] Furthermore, a filter box is slidably connected inside the collection box, and one side of the collection box is fixedly connected to the three output ends of the fan.

[0010] Furthermore, the outer wall of the support frame is fixedly connected to two symmetrical brackets, and the brackets are slidably connected to a sliding rod inside the brackets.

[0011] Furthermore, one end of the sliding rod is fixedly connected to a limiting rod two, and a pin is slidably connected inside the bracket two.

[0012] Furthermore, the pin is disposed inside the sliding rod, and the pin is used to position the sliding rod.

[0013] Furthermore, the second ion air bar is slidably connected to one side of the support plate via a first limiting rod, which is used to limit the position of the second ion air bar.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the automotive trim parts are transported to the support cover via a spraying transmission line. A fan is used to deliver clean airflow to the automotive trim parts for simple dust removal. Then, a hydraulic rod is used to raise and lower the ion air bar under the support plate, which in turn adjusts the angle of the ion air bar installed on one side of the support cover. By adjusting the ion air bar, a highly efficient dust removal effect is achieved, thereby improving the practicality of the device.

[0016] 2. In this utility model, by pulling the sliding rod to slide inside the bracket, the limiting rod two limits the automotive trim parts. Then, the fan three collects the processed dust through the collection hopper and transmits it to the collection box. The dust is then collected and filtered by the filter box inside the collection box and discharged into the equipment to achieve the filtration effect, thereby improving the practicality of the device.
