Description
Technical Field
[0001] The utility model relates to the technical field of printing machines, in particular to a printing machine with a photo recognition function. Background Art
[0002] A printing press is a mechanical device used to transfer ink or other types of pigments onto substrates such as paper, plastic, and metal foil. It uses pressure to replicate and mass-produce text and patterns. It is widely used in the manufacturing process of books, newspapers, magazines, packaging materials, and other printed materials. It is an indispensable core equipment in the modern printing industry. According to different printing principles and uses, printing presses can be divided into various types such as letterpress printing presses, gravure printing presses, offset printing presses, and screen printing presses.
[0003] Traditional printing equipment usually lacks an effective online quality monitoring system, and printing quality problems are often not discovered until the finished product is produced, resulting in a high scrap rate. In addition, since traditional printing equipment usually only prints on printing materials of specific sizes and types, for printing materials of different thicknesses or materials, traditional printing equipment usually needs to replace or adjust multiple parts, which has poor adaptability and affects production efficiency. In addition, during the printing process, the material is prone to offset, affecting the printing accuracy, resulting in unclear printed patterns and inaccurate positioning, reducing the quality of the printed products. In addition, due to the lack of an effective flattening structure, traditional printing equipment may cause wrinkles or curling of printed materials during transportation, which not only affects the printing effect, but may also cause machine failure or shutdown.
[0004] Therefore, those skilled in the art provide a printing machine with a photo recognition function to solve the problems raised in the above background technology. Utility Model Content
