Description
Technical Field
[0001] The utility model relates to the field of printing presses, in particular to a coating device with switchable extrusion rollers and plate rollers for feeding. Background Art
[0002] The working principle of a printing press is to make the text and images to be printed into a printing plate, install it on the printing press, and then apply ink to the areas with text and images on the printing plate manually or by a printing press, and then transfer it directly or indirectly to paper or other printing materials (such as textiles, metal plates, plastics, leather, wood boards, glass and ceramics), thereby reproducing a printed product identical to the printing plate.
[0003] The squeeze rollers (also called impression rollers or impression wheels) in a printing press are an indispensable key component in the printing process. Their main function is to apply the necessary pressure during the printing process to ensure that the ink is transferred evenly and clearly from the printing plate to the substrate (such as paper, plastic film, etc.).
[0004] The plate roller is a stick-shaped component used to support and transfer the printing plate in a printing press. It usually works together with the squeeze roller to complete the printing process. The main function of the plate roller is to ensure that the printing plate remains flat and stable during the printing process, thereby ensuring the quality of the printed product.
[0005] When an existing printing press needs to print things of different materials, it is necessary to replace different types of extrusion rollers. Usually, the extrusion rollers are removed from the printing press, and then different extrusion rollers are installed in the printing press. The replacement efficiency is low, and a lot of time is wasted on disassembly and installation. After installation, the extrusion roller may not be parallel to the plate roller, resulting in the need to debug the extrusion roller, affecting processing efficiency.
[0006] Therefore, it is necessary to propose a coating device with switchable extrusion roller and plate roller feeding to solve the problems raised in the above background technology. Utility Model Content
