Wide-line printer and cleaning method

Abstract

The invention provides a wide-line printer capable of using different types of ink in a transforming mode and a wide-line printer cleaning method. The wide-line printer comprises a printing head, a printing word cart, an ink supply system composed of a main ink box, an auxiliary ink box and an ink delivering tube and a cleaning device. The main ink box is installed in the printing word cart, and an ink outlet of the main ink box is detachably connected with the printing head. The ink leading-in end of the ink delivering tube is detachably connected with an ink outlet of the auxiliary ink box, and the ink output end is connected with an ink inlet of the main ink box. The cleaning device capable of being connected with the main ink box is used for cleaning the main ink box and the ink delivering tube. The cleaning method comprises the steps of a, disconnecting the printing head and the ink outlet of the main ink box and sealing the ink outlet of the main ink box; b, dismantling the ink outlet of the auxiliary ink box from the ink leading-in end; c, connecting the cleaning device and the main ink box; d, using the cleaning device to clean the main ink box and the ink delivering tube; and e, enabling the printing head and the ink outlet of the main ink box to be connected.

Description

technical field [0001] The invention relates to a wide-line printer capable of large-format inkjet printing and a cleaning method for the printer. Background technique [0002] With the development of computer multimedia technology, wide-line printers capable of large-format inkjet printing are widely used in the field of professional image printing. Because the ink demand of this kind of wide-line printer is large and the printing head needs to be kept flexible and convenient, generally the small-capacity main ink tank and the printing head are fixed on the reciprocating print carriage, and the main ink tank is fixed to the printing head. Provide ink, while the large-capacity auxiliary ink box is detachably installed on the main body of the wide-line printer and supplies ink to the main ink box through a flexible ink delivery tube. After the ink in the auxiliary ink box is used up, replace it with a new one. The ink cartridge, the main ink cartridge, the auxiliary ink cart...

AI Technical Summary

Problems solved by technology

When different types of ink are mixed, they generally react and produce precipitation, which makes the ink unusable. The existing wide-line printers use the ink in the auxiliary ink box to clean the print head from the print head through the ink delivery tube and the main ink box. Continuously ejected to clear the nozzle, however, when the new auxiliary ink tank is replaced, the ink in the auxiliary ink tank is different from the original ink in the ink delivery tube, main ink tank and print head, the two types of ink The ink will react and produce precipitation, so the existing wide-line printer does not allow the use of different types of ink, so as not to block the ink pipe and then block the print head, so that the wide-line printer cannot print normally

However, in practical applications, it is often necessary to switch between different types of inks, and the structure of existing wide-line printers cannot meet this demand
