Embodiment 1

[0049] refer to Figure 1-5: Large-capacity ink bag 1, including ink bag main body 1a, small plastic disc 1b, first spring 1c, plastic boss 1d, rubber seal 1e, large plastic disc 1g, second spring 1h, exhaust outlet 1i, Pressurized water inlet 1j, large-capacity film chamber 1f, upper water inlet 1k, and ink bag water outlet 1l. One end of the PVC pipe is connected to the exhaust outlet of the ink sac, and the other end of the PVC pipe is sealed with a matching plastic plug; the pressurized water inlet 1j of the ink sac is connected to the water outlet 3b2 of the sealed ink cartridge, and a one-way valve is arranged in the middle.

[0050] Ink storage bottle 2, described ink storage bottle 2 is provided with bottle cap 2A that can be opened and filled with ink, ink pouring inlet 2a, first water outlet 2b, second water outlet 2c are set on described ink storage bottle 2, The ink pouring port 2a is used to pour bottled ink, the first water outlet 2b is connected with the upper ...

Embodiment 2

[0058] Such as Figure 7-9 The difference between this embodiment and embodiment 1 is that the ink bag has 2 channels, that is, one ink bag integrates the 2 ink bags of embodiment 1, and there are 2 pressurized water inlets correspondingly , 2 pressurized exhaust outlets, 2 large-capacity film chambers, the working principle and mode of operation are the same as in Embodiment 1.

Abstract

The invention relates to the printing industry, and particularly relates to an ink supply system capable of performing positive pressure cleaning and negative pressure ink jetting and a printer thereof. The ink supply system capable of performing positive pressure cleaning and negative pressure ink jetting comprises an ink sac and an ink storage bottom which is connected with the ink sac, and also comprises a sealing ink box which can provide constant pressure for cleaning a pipeline. The position of the ink storage bottom is higher than that of the ink sac. The position of the sealing ink box is lower than that of the ink sac. According to the ink sack capable of performing positive pressure cleaning and negative pressure ink jetting and the ink supply system thereof, cleaning of a nozzle can be simply and reliably realized so that reliability of cleaning can be guaranteed, the cleaning system of the printer can be greatly simplified, cost of the printer can be saved and corresponding cost can be reduced for customers.

Description

technical field [0001] The invention relates to the printing industry, in particular to an ink supply system capable of positive pressure cleaning and negative pressure ink jetting and a printer. Background technique [0002] With the development of science and technology, the demand for printers is also increasing, and the application fields of printers are becoming wider and wider. Now, the types of nozzles used in large-format printers are also increasing. Now there are several ways to clean the nozzles of printers on the market. For some industrial nozzles, the general cleaning method is to apply pressure to the ink with positive pressure, and then the ink is ejected from the nozzles. The cleaning system is relatively complicated, and it needs to use negative pressure. And positive pressure switch to realize the cleaning of the nozzle. When cleaning, it needs to switch to positive pressure, apply pressure to the ink, so that the ink can be ejected from the nozzle strong...
