Ultrahigh-speed digital printing machine

Abstract

The invention relates to the technical field of digital printing machines, and discloses an ultrahigh-speed digital printing machine. The ultrahigh-speed digital printing machine comprises a rack, an unwinding mechanism, a first constant-tension roller mechanism, a printing device, a printing platform mechanism, a drying mechanism and a winding mechanism, wherein the first constant-tension roller mechanism is used for conveying a medium and keeping the medium in a constant-tension state; the printing device is used for printing on the medium; the printing platform mechanism is used for conveying the medium and cooperating with the printing device to complete printing on the medium; the drying mechanism is used for drying ink on the printed medium; and the winding mechanism is used for storing the medium. Compared with the prior art, the ultrahigh-speed digital printing machine has the advantages that a guide-belt-free type structure is adopted, and the medium is used for conveying, so that the printing precision can be effectively improved; and the printing efficiency is effectively improved through high-speed conveying of the medium. Moreover, the unwinding mechanism, the winding mechanism, the printing device and the drying mechanism are integrally designed, so that the consistent tension of the medium during printing and the medium conveying accuracy can be guaranteed, the size of the printing machine can be smaller, the space is saved, and the overall accuracy of the printing machine is improved.

Description

technical field [0001] The invention relates to the technical field of digital printing machines, in particular to an ultra-high-speed 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.

Problems solved by technology

[0003] Existing digital printing machines mainly have two forms, one is a scanning digital printing machine, as shown in patent number CN202010044147.6, which discloses a scanning digital textile printing machine, the nozzle is installed on the nozzle bracket, through The nozzle bracket moves back and forth on the beam for scanning digital printing. Since the nozzle moves back and forth takes time, the production efficiency of the scanning digital printing machine is low; the other is the guide belt digital printing machine, such as the patent number CN02107229 As shown in .9, a belt-guiding type digital jet printing machine is disclosed. The nozzle is fixed, but the transmission of the printing medium is carried out by means of a belt-guiding belt. Compared with the scanning-type digital printing machine, the belt-guiding type The advanced digital printing machine effectively improves the printing efficiency, but when the digital printing machine of the guide belt type is printing, because the printing medium is transmitted by the guide belt, the guide belt cannot be transmitted completely synchronously with the printing medium, and there will be some problems. For example, when the guide belt is started, the guide belt will start first and then drive the printing medium to be transported. The guide belt will travel 2mm to 10mm longer than the printing medium. When the guide belt stops, the guide belt stops, but the printing The medium will continue to transmit a distance of 2mm to 10mm. Different printing medium materials and different belt transmission speeds will cause different distance deviations. When there is a distance deviation, it will affect the printing of the digital printing machine. Accuracy, especially when the conduction belt operates at ultra-high speed, printing accuracy becomes a technical difficulty
