Embodiment 1

[0074] refer to Figure 6-19 : large-format printer vacuum degassing and automatic pressurization continuous ink supply system, including a large-capacity ink storage bottle 3, the ink storage bottle 3 is provided with a bottle cap 3A that can be opened and filled with ink, for pouring bottled ink . Described ink storage bottle 3 is provided with air outlet 3b, the first ventilation port 3c, the first water outlet 3d, and described air outlet 3b connects the air pump 7 that degasses the ink in ink storage bottle 3, so The ink storage bottle 3 is sealed under the working state of the air pump 7, the first air vent 3c is connected to the first pressure sensor and the intake valve, and the first pressure sensor and the intake valve work together to make the ink storage Maintain a constant vacuum (negative pressure) A in the bottle 3, and the first water outlet 3d is sequentially connected to the ink suction pump 6 and the sealed container 4 through pipelines; the connecting pipe...

Embodiment 2

[0091] refer to Figure 19 The difference between the present embodiment and the first embodiment is that the press device is a mechanical extrusion device, and the mechanical extrusion device includes a baffle plate 4c on one side of the ink bag and a pressure plate 4g on the opposite side, The pressure plate 4g is connected to the horizontal push rod 4k, and the horizontal push rod 4k is penetrated in the fixed plate fixing plate 4h for guiding the horizontal push rod 4k, and the pressure plate 4g and the pressure plate fixing plate 4h are connected with The third spring 4i. Such as Figure 19The magnet 4e that cooperates with the magnet sensor is heat-sealed on the inner surface of the ink bag 4d with a plastic film, and the pressure plate 4g with the third spring 4i is used to press the ink bag 4d on the outer surface of the ink bag 4d, and the pressure plate fixing plate 4h is used In order to ensure that the pressure plate 4g moves horizontally and stably in the H dire...

Embodiment 3

[0093] The difference between this embodiment and the first embodiment is that the sensor is a liquid level sensor, and the other structures and implementation methods of this embodiment are completely the same as those of the first embodiment.

Abstract

The invention relates to a vacuum degassing and automatic boosting continuous ink supply system of a large-format printer, which comprises an ink storing bottle, wherein the ink storing bottle is provided with an openable ink injecting bottle cap and is sealed; an air outlet, a first ventilating opening and a first water outlet are arranged on the ink storing bottle; the air outlet is connected with an air pump; the first ventilating opening is connected with a first pressure sensor and an air inlet valve; the first pressure sensor and the air inlet valve play a role together so that the ink storing bottle maintains a constant vacuum degree; the first water outlet is sequentially connected with an ink sucking pump and an ink bag by a pipeline; the ink bag is provided with a first water inlet, a first exhaust opening and a second water outlet; the first water inlet is connected with an outlet of the ink sucking pump; the first exhaust opening is configured with a plug for seal; the first water outlet is connected to an ink path of the printer; and a baffle plate for carrying out single-side support on the ink bag is fixed to the ink bag side. The invention also comprises a pressureapplying device for compressing the ink bag to extrude ink and a sensor for measuring the ink residual amount in the ink bag, wherein the sensor is electrically connected with the ink sucking pump. The invention can simply and conveniently realize the continuous supply of the ink and solve the problem of ink interruption of printing of continuous ink supply systems of large-format printers.

Description

technical field [0001] The invention relates to a vacuum degassing and automatic pressurization continuous ink supply system for a large-format inkjet printer. Background technique [0002] With the development of computer multimedia technology, large-format inkjet printers have been widely used in the field of professional graphics. However, the original ink cartridges of large-format inkjet printers are often small in capacity, expensive and of a single type. In order to reduce the cost of use and expand the application field, while avoiding the discontinuity of printing caused by frequent replacement of ink cartridges and affecting work efficiency, continuous ink supply The system was born accordingly. [0003] At present, many large-format inkjet printer manufacturers on the market have set up many obstacles between the printer nozzle and the ink supply system in order to ensure the market sales of their brand inks. At the same time, vacuum degassing is used on the orig...
