Preparation method of copper plate mold for pearl cotton board printing

Abstract

The invention relates to the technical field of pearl cotton board printing, in particular to a preparation method of a copper plate mold for pearl cotton board printing. The method comprises the steps that the perimeter of a copper plate is designed according to the thickness of a pearl cotton board, the thicknesses of the pearl cotton board is divided into five thickness sections of 0-30mm, 30-40mm, 40-50mm, 50-60mm and 60-70mm, the practical perimeter of the copper plate is obtained according to a calculation formula of each thickness section, the copper plate is machined into a hardware part in a circular roller shape, the hardware part is polished and plated with chrome, printing patterns are engraved to the hardware part through laser, and therefore the copper plate mold is obtained.The size of the product printed by the copper plate mold meets requirements, the quality is ensured, the technical problem that the product size cannot be reach standards when printing is carried outon a pearl cotton board in the prior art is solved, continuous printing can be achieved on a copper plate machine, and production efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of pearl cotton plate printing, in particular to a method for preparing a copper plate mold for pearl cotton plate printing. Background technique [0002] Pearl cotton is a new type of environmentally friendly packaging material. It has many advantages such as water and moisture resistance, shock resistance, sound insulation, heat preservation, good plasticity, and strong toughness. It is widely used in the packaging of various products such as computers, TVs, and audio. For the printing of pearl cotton sheets, there are mainly screen printing and copperplate printing. Since the screen printing equipment is printed one by one (take out one after printing, and then put another in for printing), and the screen printing screen needs to be cleaned frequently and dried, production The efficiency is low (about 6000 pieces / day / 3 people), while copper plate printing can be produced continuously, which has the advant...

AI Technical Summary

Problems solved by technology

When the copper plate machine is produced, the size of the copper plate mold (that is, the circumference) is customized according to the size of the product, but for the printing of the pearl cotton sheet 4, the thickness of the pearl cotton sheet is different, and the difference is very large, so if the size of the product is To customize, the size of the produced product is smaller than the specified requirements, which does not meet the requirements and seriously affects the quality of the product
