Description

Technical Field

[0001] The utility model relates to the technical field of cleaning of a roller type screen printing machine, in particular to an automatic cleaning nozzle of a roller type screen printing machine. Background Art

[0002] A printing press is a machine used to print text and images. Modern printing presses generally consist of mechanisms such as plate loading, inking, embossing, and paper feeding. Its working principle is as follows: the text and image to be printed are first made into a printing plate and mounted on the printing press. Ink is then applied manually or by the printing press to the areas of the plate where the text and image are located. The ink is then transferred directly or indirectly to paper or other substrates (such as textiles, metal plates, plastics, leather, wood, glass, and ceramics), producing a printed product identical to the printing plate.

[0003] Among them, the printing roller is a key component in the printing process, and the cleanliness of its surface directly affects the quality of the printed product. During the printing process, ink, paper scraps and other dirt will adhere to the surface of the roller. If it is not cleaned in time, these dirt will gradually accumulate, causing the printed product to appear blurred, ghosting and other problems, and even affecting the normal operation of the equipment. In the existing technology, the printing roller is cleaned by nozzles to clean the printing roller. However, in order to improve the cleaning effect of the printing roller, it is generally necessary to set up multiple nozzles to clean the printing roller. However, this increases the cleaning cost of the printing roller. At the same time, the flushing effect on the area between the nozzles is low, which can easily affect the cleaning efficiency due to uneven cleaning effect. Utility Model Content
