[0002] The recycling device for LED roller coating lines is an environmentally friendly equipment specially used in the coating process. It is designed to recycle excess or unused coating materials in the production process. The device collects and purifies the coating that does not adhere to the substrate during the roller coating process through precise control and filtration, preventing waste and reducing emissions to ensure the sustainability of production. It is usually equipped with an efficient recycling device that can put the recycled coating into use again, reducing material costs and reducing environmental pollution. In addition, the device can also reduce the number of cleanings and improve the efficiency of the production line. It is an important part of green manufacturing and is widely used in the field of LED lamp production.

[0003] After searching, the Chinese patent announcement number is: CN218925118U, which discloses an enameled wire lubricating oil coating device with a recycling function, including a main body, an oil storage box is fixedly connected to the bottom end of the inner surface of the main body; a first oil coating roller is movably connected to the inner wall of the main body, a fixed through-hole is opened on one side of the main body, and a collection box is fixedly connected to one side of the bottom end of the inner surface of the oil storage box. This utility model can connect the scraper and the collection box by a fixed block, and at the same time use a fixed rod to connect the two sides of the scraper to the second oil coating roller, which improves the stability of the scraper installation. When the second oil coating roller rotates, the scraper can be used to scrape the surface of the oil-absorbing cotton, which prevents the surface of the oil-absorbing cotton from absorbing a large amount of lubricating oil and increasing costs.
