Laminating process in our country is widely used in all kinds of packaging decoration printed matter, a variety of binding forms of books, this book, calendar, map, is a very popular printing surface processing technology. After coated printed matter, its wear resistance, folding resistance, tensile and moisture resistance have been greatly enhanced. Coated film technology is divided into coated film and pre-coated film, and pre-coated film in the application without glue and solvent, is the development trend of safe and environmentally friendly packaging products. The precoating machine mainly consists of the input part of printed matter, the composite part of hot press, the transmission system and the computer control system.
Traditional laminating machine hot-pressing composite roller adopts heat conduction oil heating method, has many disadvantages: heat conduction oil in a long time after working, and air contact will produce carbon structure, and attached to the inside of the roller body, resulting in roller surface temperature due to different wall thickness fluctuant temperature difference, greatly king sound laminating uniformity; Heat dissipation is large, heat conversion efficiency is low, so energy consumption is high; Oil spills and other problems pose safety risks.
Hunan QiJieXin electronic technology co., LTD. (www.zgqjkj.com/www.qjxdz.com); The production of electromagnetic heating roller use electromagnetic induction to make the roller body heating, no need of heat conduction oil, eliminate oil leakage and other safety hazards, effectively reduce the production energy consumption. Due to the multi-stage temperature control, the temperature difference on the surface of the roller can be controlled within ±1℃, which greatly improves the uniformity of the coating and ensures the product quality. Due to the above high temperature uniformity, energy saving and environmental protection advantages, electromagnetic heating roller will become the preferred hot pressing composite roller of the laminating machine.
