Printers for Rigid Signs

Abstract

The invention provides a printer for hard boards. The printer is wide in application range, few in printing process, high in printing efficiency and capable of enabling the equipment investment of hard signboard manufacturers to be small. The printer comprises multiple thermal sensitive / thermal transfer printing heads, all the printing head are arranged in two lines, the printing heads on the same line are arranged at intervals, and all the printing heads on the first line and the corresponding adjacent printing heads on the second line are arranged in a staggered manner in the Y direction; among the printing heads on the same line, the printing head at the head end or the tail end and at least one printing head at the middle can move in a reciprocating manner within a set distance near original positions of the printing heads in the X direction; and when printing is conducted, the effective printing length formed by the two lines of the printing heads in the X direction is equal to the width of a set printing range of to-be-printed consumables, wherein the printing consumables are composed of hard substrates and surface films which are fixedly connected to the surfaces of the substrates and can be printed with character and pattern signs. By means of the structure, the application field of the printer can be effectively improved, and scratch damage, caused by burr edges of the hard printing consumables, to the printing heads at the two ends in a printing head assembly is effectively avoided.

Description

technical field [0001] The invention relates to a heat sensitive / thermal transfer printer, in particular to a printer which can directly print characters and patterns on a hard substrate pasted with PE, PET, reflective film or PVC film. Background technique [0002] In the prior art, all kinds of hard signboards 1 (such as electric signboards of electric power systems, highway signboards, reminder signs for tourists or passers-by in public places, etc.) made of hard substrates and plastic films printed with text patterns The production methods of warning signs and other identification signs) are roughly as follows: [0003] 1. Silkscreen (see figure 1 ) [0004] First make the used screen printing screen version 4 that has been designed text pattern 7 on it, and carry out silk screen printing as the original manuscript. [0005] Use the screen printing ink 41 , the scraper 5 , the substrate (ie the hard substrate 2 ), the printing device 6 (such as the screen frame for fi...

AI Technical Summary

Problems solved by technology

[0007] 1) Since the screen plate 4 is made by engraving plate-making or photosensitive plate-making, once the screen plate 4 is completed, its content has been fixed and cannot be changed, resulting in a single structure, which is not universal and has a narrow scope of application

[0008] 2) The scraper 5 is used to scrape the screen printing ink 41, resulting in low production efficiency, high labor cost and large material consumption

[0012] 1) There are many operating procedures and labor intensive, resulting in high production costs

[0013] 2) The plastic film 3 and the hard substrate 2 are cut more, resulting in unnecessary material waste

[0015] 4) Manufacturers of hard signage 1 need to configure laminating equipment, which will increase additional investment
