AI Technical Summary

Technical Problem

The existing double-layer label printing process is complicated, inefficient, requires multiple sets of equipment, and has high production costs.

Method used

A double-layer composite label printing device is used to achieve direct slitting and lamination of base paper through roll feeding, slitting, flipping and laminating roller components, eliminating the separate printing and rewinding steps. The roll feeding mechanism is used to transport the printed material, the slitting mechanism cuts along the length direction, and the flip frame changes the inner paper path to composite the inner paper with the outer paper.

Benefits of technology

It improves production efficiency, reduces the number of equipment, reduces production costs, ensures the stability of composite film quality, increases production speed, and saves energy consumption.

Abstract

The invention discloses double-layer composite label printing equipment and a printing method. Comprising a rack, a roll feeding mechanism, a slitting mechanism arranged on the rack and used for slitting raw paper into inner paper and outer paper, a stripping mechanism arranged on the rack and used for stripping bottom paper of the inner paper formed by slitting the raw paper, and an overturning frame arranged on the rack and used for overturning the inner paper with the bottom paper stripped. The paper guide roller assembly is arranged on the machine frame and used for guiding the overturned inner paper, and the composite roller assembly is arranged on the machine frame and used for compositing the outer paper formed through slitting and the inner paper guided by the paper guide roller assembly to form a composite film. The plurality of tensioning rollers are used for tensioning the composite film; and the cold ironing and rolling assembly is used for carrying out cold ironing and rolling on the composite film. The automatic label printing machine has the advantages that the unwinding and winding processes performed when an upper label and a lower label are printed on two different printing materials respectively are omitted, the production efficiency is improved, meanwhile, the number of devices is reduced, the occupied space of the devices is reduced, and the production cost is saved.
