Novel scanning digital printing machine for printing paper

Abstract

The invention relates to the technical field of digital printing, and discloses a novel scanning digital printing machine for printing paper. The novel scanning digital printing machine comprises a machine frame, a spray nozzle assembly, a printing platform mechanism and an ink path system with circulation. The spray nozzle assembly comprises a spray nozzle and is used for printing. The printing platform mechanism is located below the spray nozzle assembly. The ink path system with circulation supplies ink to the spray nozzle, and the spray nozzle is an Epson non-industrial spray nozzle. The spray nozzle assembly is used for printing, the ink path system with circulation is connected with the spray nozzle and supplies ink to the spray nozzle, and an ink supply assembly supplies ink to the ink path system, with circulation, of the whole spray nozzle. An ink circulation assembly is used for controlling the circulation and pressure difference relation of the spray nozzle. A positive and negative pressure control assembly is connected with the ink circulation assembly and used for controlling the positive and negative pressure of the ink circulation assembly. Through the ink circulation assembly and the positive and negative pressure control assembly, the whole ink path system with circulation can keep stable negative pressure, and therefore ink supply of the whole digital calico printing machine can be stable, the structure is simple, and the production efficiency is effectively improved.

Description

technical field [0001] The invention relates to the technical field of digital printing, in particular to a novel paper scanning digital printing machine. Background technique [0002] Digital printing is printing with digital technology. Digital printing technology is a high-tech product that integrates machinery, computer, electronic information technology and gradually formed with the continuous development of computer technology. The production process of digital printing is simply put It is through various digital means, such as: scanning, digital photos, images or various digital patterns processed by computers, input into the computer, and then processed by the computer color separation printing system. A special dye (reactive, disperse, acidic main paint) can be spray-printed directly onto various fabrics or other media, and after processing, various high-precision printing products required can be obtained on various textile fabrics. [0003] At present, the applic...

Problems solved by technology

[0003] At present, the application principle of the digital printing machine on the market is the ink system based on the siphon principle. This principle has a complex structure and poor stability. It will make the ink system unstable with the change of ink concentration, viscosity and temperature. , the nozzle printing will have color changes, ink breakage, ink shortage and other phenomena; it will seriously affect the production efficiency of the equipment and cause great losses to the manufacturers.
