A food packaging film preparation system

Abstract

The invention discloses a food packaging film preparation system, which sequentially includes a preheating device, a coating device and an air-drying device; the packaging film is conveyed by a conveying roller, which avoids repeated loading and unloading processes in multiple processes, and avoids manual handling Rolling up and down, high work efficiency, low cost, reduced working time, reduced production cycle, and saved manpower. In addition, multiple processes such as one-time pretreatment, transmission, printing, and air drying are used to prepare food packaging films, and the use effect is good. The pretreatment adopts electric heating and air blowing to eliminate dust on the surface of the packaging film and soften the packaging film, so that the subsequent coating process can be better printed on the surface of the packaging film. Coating and printing are carried out on the surface of the packaging film by means of a doctor blade and a coating roller, and the printing effect can be improved through the elastic pressing roller, and the use effect is good. Finally, multiple air supply devices are used to air-dry the surface of the printed packaging film to quickly dry the printed color on the surface of the packaging film.

Description

technical field [0001] The invention relates to the technical field of food packaging films, in particular to a food packaging film preparation system. Background technique [0002] Food packaging film is used to wrap the surface of food. It is mainly used to isolate the entry of decomposing microorganisms and foreign pollutants, to prevent and prolong the deterioration of food. In the process of food packaging, food packaging film is often used for printing and packaging. [0003] The packaging film printing preparation in the prior art is too complicated, and multiple processes such as pretreatment, transmission, printing, and air-drying are required. Most of the current production enterprises use multiple mechanical equipment to process separately, and the method of manually handling packaging film rolls is Loading and unloading between multiple devices has low work efficiency, high cost, long production cycle, and waste of manpower. Therefore, the research and developmen...

[0003] The packaging film printing preparation in the prior art is too complicated, and multiple processes such as pretreatment, transmission, printing, and air-drying are required. Most of the current production enterprises use multiple mechanical equipment to process separately, and the method of manually handling packaging film rolls is Loading and unloading between multiple devices has low work efficiency, high cost, long production cycle, and waste of manpower. Therefore, the research and development of a food packaging film preparation system that can be prepared with high efficiency has attracted more and more attention from researchers.
