Embodiment 1

[0053] refer to Figure 4-7 : large-capacity exhaust ink bag 2 for large-format printers, including ink bag main body 2a, small plastic disc 2b, first spring 2c, plastic boss 2d, rubber seal 2e, large plastic disc 2g, second spring 2h, Exhaust port 2i and film buffer chamber 2f (preferably adopting large-capacity film buffer chamber 2f, the inner diameter of the ink bag film buffer chamber is 33 mm, and the height is 5.5 mm). What ink sac vent end is connected is an end of PVC pipe 3, and the other end of PVC pipe 3 is sealed with supporting plastic plug 4.

[0054] The PVC pipe 3 and the ink bag exhaust port 2i are connected together with special sealing glue to ensure that the PVC pipe is closely connected with the exhaust port and is not easy to fall off.

[0055] The plastic plug 4 can be closely matched with the other end of the PVC pipe 3, which can ensure that the PVC pipe is completely isolated from the outside world and that the ink bag will not leak.

Embodiment 1

[0060] The ink sac provided by embodiment one (the film buffer chamber 2f that adopts, the inner diameter of the ink sac film buffer chamber is 33 millimeters, and the height is 5.5 millimeters) is better than the supporting ink bag of the EPSON5 generation micro piezoelectric nozzle on the market (the diameter of the ink sac is between 1 and 2 f). 29 mm, the height of the chamber is 3.5 mm) doubles the capacity of the film buffer chamber, but the continuous printing time of the printer has increased by at least 2.5 times, effectively improving the printing efficiency and printing quality.

Embodiment 2

[0062] 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 also 2 exhaust pipes correspondingly. The top of the exhaust pipe is provided with a clip for sealing the exhaust pipe, and two large-capacity film buffer chambers, the working principle and operation method of which are the same as those in Embodiment 1.

Abstract

The invention belongs to the field of print equipment and relates to a large-capacity exhaust ink bag for a large-width ink-jet printer. The large-capacity exhaust ink bag for the large-width ink-jet printer comprises an ink bag main body, and a small plastic disc, a large plastic disc and plastic bosses, which are arranged in the ink bag main body, wherein the plastic bosses are respectively supported between the small plastic disc and the large plastic disc through a first spring and a second spring; rubber seal components are fixed at the joint of the plastic bosses and the ink bag main body; a film buffering chamber is formed by the ink bag main body, the large plastic disc and the plastic bosses, an exhaust opening is formed in the film buffering chamber, and the exhaust opening is connected with an exhaust pipe with a shutoff valve. The large-capacity exhaust ink bag for the large-width ink-jet printer, provided by the invention, easily solves the problem that the large-width printer cannot continuously print for long time in a simple manner, and greatly improves the print speed and the print quality of the large-width printer, thereby better meeting the requirements of people on the speed and the quality of the printer.

Description

technical field [0001] The invention belongs to the field of printing equipment, and relates to a large-capacity exhaust ink bag for a large-format ink-jet printer. Background technique [0002] Now with the development of science and technology, large-format printers have been widely used in various fields, and people have higher and higher requirements for the printing quality and printing speed of printers. The printers on the market are still relatively lacking in printing quality and printing speed. The important reason is that the nozzles are prone to ink breakage during printing, and they cannot print continuously for a long time, and the frequency of cleaning the nozzles in the middle is relatively high. In this way, the printing speed will be greatly reduced, and the quality of the printed image will be greatly affected. [0003] At present, in order to increase the flow replenishment speed of ink and overcome the resistance of the pipeline system for long-distance...
