Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of printing equipment, in particular to a printing device for producing PVC films. Background Art
[0002] The main component of PVC is polyvinyl chloride, which is slightly yellow and translucent and shiny. It is more transparent than polyethylene and polypropylene, but less transparent than polystyrene. Depending on the amount of additives used, it is divided into soft and hard polyvinyl chloride. Soft products are soft and tough, and feel sticky. The hardness of hard products is higher than that of low-density polyethylene, but lower than that of polypropylene, and whitening will occur at the bends. Common products: plates, pipes, soles, toys, doors and windows, wire sheaths, stationery, etc. It is a polymer material that uses a chlorine atom to replace a hydrogen atom in polyethylene.
[0003] PVC film can be divided into two categories: printing grade and ordinary packaging grade. Among them, printing grade PVC film, as the name implies, is used for printing and can be processed into a type of printed label. Most beverages on the market use PVC film labels, such as labels used on the outside of bottles of mineral water, black tea, green tea, etc. Ordinary packaging grade PVC film can also be used for printing, but the printing effect is not fine, and the number of printable colors is small, generally printing one or two colors. The existing PVC film printing device generally has a raw material winding mechanism in front of the printing mechanism and a finished product winding mechanism in the back, which is used to place and pull the PVC film so that it can pass through the printing mechanism smoothly and be wound up. However, the existing raw material winding mechanism and finished product winding mechanism are generally only provided with one winding roller. When the raw material winding mechanism releases the raw material or the winding roller winds up enough PVC film, it needs to be disassembled from the bracket, and then the new winding roller is installed on the original bracket. Only after the installation is completed can it continue. This disassembly and assembly takes a lot of time and the production efficiency is not high. Utility Model Content
