In order to improve the anti-corrosion and other properties of parts, painting is usually required on many parts. At present, most of the painting work for mass-produced parts is still done manually. Because paint usually contains more harmful substances, especially the concentration of benzene volatilized during the painting process is quite high, which is extremely harmful to painting workers; The harmful substances in the paint can not only be inhaled through the lungs, but also absorbed through the skin, so the safety protection during the manual painting process is more difficult.

The pollution problem of the above-mentioned paint mist has always been an urgent problem to be solved in this field, and many researchers have also proposed many improvement schemes, such as Chinese Patent Application No. 201910518570.2, the application publication date is September 24, 2019, and the name of the invention is: a Paint mist elimination equipment for automatic paint spray booths, a paint mist elimination device for automatic paint spray booths in this application, including an air circulation device and a paint mist elimination device; the air circulation device includes a first air intake, and a circulation below the first air intake The special filter screen for paint mist and the activated carbon filter screen are sequentially arranged in the air duct; the first air suction port is located below the workpiece to be painted; the circulating air duct is connected to the air outlet structure on the top of the automatic painting room; the circulating air duct is close to the outlet. A circulating fan is arranged near one end of the wind structure; the paint mist elimination device is arranged on both sides of the automatic painting room relative to the movement direction of the workpiece to be painted, and at least one paint mist elimination device is arranged on both sides. The paint mist elimination equipment for automatic paint spraying room of the application can absorb the paint mist and collect it, but as long as the filter cotton mesh or filter is used in the collection process, the filter cotton mesh or filter needs to be replaced regularly, otherwise it is easy to be blocked by paint, and It is difficult to recycle the paint in the filter cotton mesh or the filter, which is not conducive to the recycling of paint mist.

In addition, the efficiency of manual painting is low and the quality of painting is poor, and there are different levels of sprayed solid particles during the painting operation, which will not only cause environmental pollution, but also cause a lot of waste of paint resources. With the increasing labor cost, the traditional manual painting requires a large amount of labor, and the painting cost is very high, which has been difficult to meet the needs of industrial automation development. In order to replace the manual painting operation, there are also many technical solutions related to mechanical painting and plastic spraying equipment. However, the existing mechanical painting and plastic spraying equipment will also generate a large amount of scattered paint mist during the painting process, which will seriously pollute the surrounding environment and cause a large amount of paint. waste. In response to the above problems, the applicant has successively proposed a patent titled "A Automatic Paint Spraying Equipment (Application No. 201711276175.5)" and a patent titled "Paint Spraying Equipment Paint Mist Circulation Recovery System and Automatic Paint Spraying Device (Application No. 201711276175.5)" It is the patent application of 201910406000.4)”, the above two applications have a good recycling effect on paint mist, in order to improve the efficiency of paint mist circulation, it is necessary to set up multiple fans to drive the paint mist in the painting room. , a larger number of fans are required. In addition, due to the small space in the painting room, the gas flow caused by the circulating suction in the painting room will affect the normal painting of the parts, so the air flow in the painting room also needs to be optimized.
