Technical Field

The invention relates to the technical field of printing, in particular to a printed matter separating device and a printed matter separating method.

Background

Printed matter is a variety of printed products, which are a general term for various finished products produced using printing techniques. In daily life, newspapers, books and magazines, maps, posters, advertisements, envelopes, letter papers, file bags, trademarks, labels, business cards, invitation cards, bank notes, greeting cards, desk calendars, wall calendars, picture albums, various certificate cards, packing boxes, gift boxes, circuit boards and the like which people contact are in the category of printed matters. The printed matter is almost filled in the fields of clothes, food, live and walk of people, and is very close to the life of people. In the process of producing the image-text printing, it is very important to select a printing medium. The printing effect and cost of the printed product are also influenced by the printing method and the printing medium used, so that a basic understanding of the printing medium should be provided. The printing media are of various kinds, most commonly paper and cardboard, and secondly, there are cloth, fiber materials, plastic sheets (films), metal skins, and surfaces of various common electric appliances in life. The media used for printing today are paper based. Various types of paper have respective uses, and the paper types are very various, including 'coated paper' (commonly called 'powdered paper') commonly used for high-grade color printing, and the surface of the chemically coated paper pressed by a roller is extremely smooth and glossy, so the paper is also generally called 'glossy coated paper'. The surface of the glossy coated paper is subjected to additional processing to obtain a very smooth but non-glossy effect, and the glossy coated paper is called 'matte coated paper' (commonly called 'matte powder paper') and is suitable for color printing of fine dots.

Printed matters such as color boxes and packing paper are visible everywhere in daily life, and a layer of sticking film is generally required to be stuck on the surface of paper for more attractive appearance and certain waterproof and moistureproof performance. Because in the printing process, the paper is generally stacked for convenient placement and transportation. In the film laminating process, the paper needs to be separated separately and then sent to a film laminating device for film lamination. With the development of technology, the existing equipment for separating paper sheets is mature and can rapidly separate the paper sheets. In the processing process, one paper separating device generally corresponds to one film pasting device, but the subsequent processing process is relatively slow, so that the paper separating device has to be stopped frequently, and the production resources are wasted.
