Printing device with dye instant mixing function

Abstract

The invention discloses a dye instant mixing printing device, which comprises a frame, a printing roller one, a printing roller two, a pressing roller, a dye storage tank one, a dye storage tank two, a dye mixing tank, a dye collecting tank and a circulating pump. Printing roller 1 and printing roller 2 are arranged above the frame, printing roller 1 and printing roller 2 are arranged in parallel, printing roller 1 and printing roller 2 are provided with pressing rollers, dye storage tank 1 and dye storage tank 2 are arranged above the frame , the dye storage tank 1 and the dye storage tank 2 are connected to the dye mixing tank through the dye conveying pipe. The dye recovery pipe and circulation pump are connected to the dye mixing tank, and the bottom of the dye mixing tank is provided with rotatable dye nozzles corresponding to the printing roller 1 and the printing roller 2 up and down. The dye storage tank 1 and the dye storage tank 2 can be used to store different dyes respectively, and the two different dyes can be mixed in real time according to the needs, so as to avoid the waste of the dyes after mixing, which is energy-saving and environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to a dye instant mixing printing device. Background technique [0002] With the rapid development of the printing industry, in order to meet the needs of different industries in all walks of life, printing machines are developing in the direction of multi-color, multi-functional and in-line processing, and the printing speed is also continuously improving. At present, most printing machines use inkjet printing. When the printing machine is printing, it coats the ink of each base color on the surface of each printing roller, and then each printing roller prints the ink of each color on the printing substrate in a superimposed manner. Form a color pattern, because some colors need to be mixed with two or more different colors during inkjet printing, usually the colors are mixed and configured in advance, and then the mixed ink is jet printed, but because inkjet printing always Try t...

Problems solved by technology

At present, most printing machines use inkjet printing. When the printing machine is printing, it coats the ink of each base color on the surface of each printing roller, and then each printing roller prints the ink of each color on the printing substrate in a superimposed manner. Form a color pattern, because some colors need to be mixed with two or more different colors during inkjet printing, usually the colors are mixed and configured in advance, and then the mixed ink is jet printed, but because inkjet printing always Try to avoid the occurrence of insufficient ink. Therefore, there will always be a surplus of mixed ink, which cannot be reused. It can only be disposed of as waste dye, resulting in a waste of capital.
