Problems solved by technology

Furthermore, water-based inks and coatings are not easy to dry. Recycled paper is wetted by inks and coatings during the printing and coating process and then dried. Its expansion and contraction will vary, resulting in more overprinting problems during the printing process and increasing the scrap rate. , reducing printing speed and accuracy

Abstract

The invention relates to the technical field of printing or coating, in particular to printing / coating equipment which comprises an unwinding device, at least two groups of printing / coating devices, apost-drying device, a plurality of rollers and a winding device for winding a coiled material; the last group of printing / coating device is at least provided with a steering roller, and the coiled material unwound by the unwinding device enters the post-drying device for drying after being subjected to steering by the steering roller of the last group of printing / coating device and then is woundby the winding device; and the rollers, starting from the first group of printing / coating device to the post-drying device, are located in one plane of a non-printing surface of the coiled material. For the printing / coating equipment provided by the invention, between the printing / coating devices and the post-drying device, the non-printing surface of the coiled material is in contact with the rollers so as to limit the quality problems such as drag marks on the printing surface of the coiled material, inaccurate stretching and overprinting caused by overdrying and the like, and thus the quality of a product as well as the production speed and efficiency are improved.

Description

technical field [0001] The present invention relates to the technical field of printing and / or coating, in particular to a printing / coating equipment. Background technique [0002] Printing and coating equipment is commonly used in the printing and packaging industry. The printing / coating equipment in the printing and packaging industry is mainly of the rotary type (printing and coating on the coil), and the structure of the traditional printing / coating equipment includes satellite type, stacked type and group vertical type. [0003] The vertical printing equipment must be completely dried after each color group is printed (the guide roller will touch the printing surface during printing), and the vertical printing equipment has long length, large floor space, high energy consumption, and There are many quality problems caused by drying, which is not conducive to popularization and use. [0004] Due to the feed and discharge characteristics, positions and angles of satelli...
