Composite cylinder pressurizing ink-joiner

Abstract

The invention relates to the assemble-cylinder pressure ink-injector. Its pneumatic pressure ink supplying system includes the assemble-cylinder structure, which oppositely joints the piton rods of two pairs of cylinders with different exhausting amounts and fixes them together with connecting nuts, controls turn-on and turn-off of the electromagnetic valve in the gas circuit through the monolithic machine and the outer circuit, controls upward or downward movements of the cylinder pistons, realizes the recording of ink-injection amount in order to control injection amount of the ink box with different volumes. The strong points of the invention are: the to-and-fro pressure can effectively dredge the block of the small apertures on the spraying head, the injection and the cleaning can be implemented at the same time; the invention is suitable for various of ink-injections, and it saves the resources and protects the environment.

Description

technical field [0001] The invention relates to a printer ink filling device, in particular to a combined cylinder pressure ink filling machine. Background technique [0002] Inkjet printer ink cartridges are usually designed as disposable consumables. Not only are they expensive and wasteful, but also discarded ink cartridges will cause environmental pollution. In order to save energy, reduce waste and protect the environment, domestic and foreign users have developed and reused ink cartridges. Ink refilling equipment; ink cartridges are generally divided into two categories: 1. The nozzle and the ink cartridge are separated, and 2. The integral disposable ink cartridge is usually equipped with an ink injection hole, which is easier to refill, while the integral disposable ink cartridge does not have an ink filling hole. For the ink hole, there are two existing methods for refilling ink in this type of ink cartridge. One is to inject with pressure from the nozzle. Since the...

[0002] Inkjet printer ink cartridges are usually designed as disposable consumables. Not only are they expensive and wasteful, but also waste ink cartridges will cause environmental pollution. In order to save energy, reduce waste, and protect the environment, domestic and foreign users have developed and used ink cartridges for repeated use. Ink injection equipment; Ink cartridges are generally divided into two categories: 1. Spray head and ink cartridge split type, 2. Integral disposable ink cartridges, split ink cartridges usually have ink injection holes, which are easier to refill ink, and integral disposable ink cartridges do not. Ink holes, for this type of ink cartridge filling, there are two existing methods, one is to inject ink from the nozzle, because the nozzle outlet of the integral ink cartridge is very narrow and easy to block, it is difficult to inject ink with traditional methods, and It is easy to damage the nozzle and the printed circuit of the nozzle, but to insert the needle into the ink cartridge to refill the ink, which is easy to damage the ink cartridge, causing air to enter the ink cartridge, so that the ink cannot enter the nozzle of the ink cartridge, and it is easy to break the ink during printing

[0003] The structure of the existing integral ink cartridge filling equipment is: according to the shape and position of the nozzle of the ink cartridge, design the ink filling fixture, such as a commercially available hand-held simple fixture, and then use the fixture to fill the ink from the nozzle; remove the ink cartridge that is short of ink from the printer ink holder Finally, there will still be residual ink at the nozzle. Because the ink is oily ink, it will dry quickly and block the nozzle after contacting the air. It is impossible to add ink to the ink cartridge with the traditional method. The amount of ink filling in the ink equipment is determined by manual adjustment of the limit mechanism, which is unable to accurately adjust the amount of ink filling for ink cartridges of various capacities. Therefore, the existing ink filling methods and equipment structures have obvious defects that need to be addressed Improve
