Engineering blueprint printing unit, apparatus and method

Abstract

The invention provides an engineering blueprint printing unit, apparatus and method, and relates to the technical field of printing. The engineering blueprint printing unit provided by the invention comprises a machine frame, a printing roller, a printing head fixing device and a plurality of thermosensitive printing heads, wherein the printing roller is rotationally connected with the machine frame; the printing head fixing device is rotationally connected with the machine frame; and the multiple thermosensitive printing heads are arranged on the printing head fixing device, and printing channels for printing thermosensitive paper are formed between the printing roller and the thermosensitive printing heads. The engineering blueprint printing unit provided by the invention can print contents on the thermosensitive paper of an engineering blueprint through heating of the thermosensitive printing heads without ink and carbon powder, thus, a spring head, an ink box, a selenium drum, thecarbon powder and other common printing consumables are not needed, inconvenience caused by frequent consumable replacement is avoided, and the printing process is high in speed and efficiency and free of pollution.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to an engineering blueprint printing unit, device and method. Background technique [0002] Engineering blueprint printers, also known as large-format printers, are mainly used in large-scale industrial drawings, engineering drawings, large-format manuscript materials and other fields. At present, the common engineering blueprint printers on the market mainly include inkjet engineering printers and laser engineering printers. [0003] The working principle of the inkjet engineering printer is to control the print nozzle dot matrix ejection printing ink through the digital circuit to complete the printing process. The consumables of inkjet engineering printers are printing ink and nozzles. One ink cartridge only prints hundreds of sheets of paper, the printing speed is slow, and the nozzles are easy to clog after working for a long time. [0004] The working principle of the laser...

Problems solved by technology

However, during the working process, due to the action of high-voltage static electricity and ultraviolet rays, it is easy to produce high-concentration ozone and a large amount of organic waste gas, which will endanger human health and pollute the air.

Moreover, if solid waste such as waste ink cartridges of inkjet printers and waste toner cartridges and toner cartridges of laser printers are not disposed of properly, it will cause serious pollution to soil and water sources.
