Packaging carton double-face printing device

Abstract

The invention provides a packaging carton double-face printing device, which comprises a central printing frame, a central driving shaft is arranged in the middle of the central printing frame, a fixed end is arranged at the outer end of the central driving shaft, a guide arc-shaped groove is arranged at the middle of the fixed end, a synchronous gear is arranged at the inner end of the central driving shaft, and a synchronous motor is arranged at the shaft end of the synchronous gear; and printing rotating rollers which are arranged on the outer side of the central driving shaft. According to the packaging carton double-face printing device provided by the invention, the printing rotating rollers can be installed on the central driving shaft through horizontal sliding nesting, an adjusting rotating frame in a winding roller storage bin correspondingly arranged on the rear side of the central driving shaft loads and stores multiple printing rotating rollers at the same time through a transverse bearing shaft, the different printing rotating rollers are rotated to the rear side of a connecting sleeve by rotating the adjusting rotating frame, and a U-shaped push plate horizontally pushes the printing roller loaded on the transverse bearing shaft to the central driving shaft, so that the printing roller can be quickly adjusted and replaced, and adjustment and use are more convenient and faster.

Description

Technical field [0001] The present disclosure relates to the field of packaging carton printing and processing, and more particularly to a double-sided printing apparatus for packaging cartons. Background technique [0002] The packaging carton is mainly used for packaging and transportation of all kinds of products. The packaging carton is better than the wooden box, and its raw materials are ordinary paper, can be made with wood pulp, grass pulp, etc., while the carton can be easily recovered. Utilization, the cost is also low, and the carton can be folded, which occupies a small space, which is convenient for storage and transportation, and due to the flatness of the paper, the carton is also facilitating printing, while the carton is used for mass printing. Usually, the surface is typically transmitted, and the corresponding rotational rubber roller is typically used to printed the corresponding pattern. [0003] The Applicant found that the current packaging carton printing ...

AI Technical Summary

Problems solved by technology

[0004] In view of this, the purpose of this disclosure is to propose a double-sided printing device for packaging cartons to solve the problem that when the printing pattern needs to be adjusted, it is often necessary to disassemble and replace the corresponding printing rubber rollers. The steps are cumbersome and the replacement efficiency is low, resulting in overall processing efficiency lower question
