Braille printing equipment and braille printed matter preparation method

Abstract

The invention discloses braille printing equipment and a braille printed matter preparation method. The braille printing equipment comprises a paper feeding unit, a conveying device, a visual positioning system, a printing device, a curing device and a paper collecting unit, wherein the printing device is composed of at least one printing nozzle and a printing nozzle control system, the printing nozzles linearly move back and forth along the X direction of the braille printing equipment, and the printing nozzle control system can control the ink jet hole number and the ink outlet amount of all the printing nozzles. According to the braille printing equipment and the braille printed matter preparation method, printing preparation of large-breadth and high-height braille dots and images can be achieved through one-time paper feeding, preparation of braille images with different touch feelings such as dull polish and texture is achieved, the braille printing equipment is small in number of printing nozzles, low in cost, high in printing speed and high in efficiency, the height-diameter ratio of the printed braille points is large, and the braille points are smooth and round.

Description

technical field [0001] The invention relates to the field of braille printing, in particular to a braille printing device and a method for preparing braille printed matter. Background technique [0002] Traditional braille printing generally uses a mechanical striker marking machine, which uses a striker to impact the paper surface on kraft paper with a specific strength, so that the paper surface forms raised braille dots. This method has high requirements on paper, which must be kraft paper with high enough strength, and the price of paper is relatively high, and the braille dots are relatively easy to be ground, and the mechanical engraving method is almost impossible to produce graphic images, which limits the application of braille. [0003] CN101549592A discloses a printing device that utilizes a dispensing device to prepare Braille, uses the lateral movement of the piezoelectric glue spray valve to print Braille dots line by line, and can realize the printing of doubl...

AI Technical Summary

Problems solved by technology

This method requires the medium to pass through the printing area and the curing area multiple times for a single row of nozzles, and each printing and curing, upper and lower paper will cause paper deformation, especially for low-weight paper that cannot be printed twice, and has high requirements for the base material and needs to be re-printed. The upper and lower paper greatly reduces the printing efficiency

If multiple print curing areas are placed in a row, the cost increases significantly
