Ink box filling machine for ink-jet recording equipment

Abstract

Ink cartridge filling machine for inkjet recording equipment, including ink pipeline and its control air circuit and circuit. The upstream end of the ink pipeline is connected to the ink source, and the downstream end is connected to the ink cartridge. There is a metering container, the metering container has a built-in liquid level sensor connected to the control circuit, a pipe switch is set on the ink pipe, and the liquid level sensor is the upper, middle and lower water level probes, where the upper and middle water level probes are located on the same plane as the metering The volume enclosed by the side walls of the container is equal to the volume to be filled with ink. After the metering container with the above-mentioned liquid level sensor is used, the sensor can accurately control the taking of a set amount of ink from the ink source and inject it into the ink box, thereby improving the quality of the ink box.

Description

technical field [0001] The present invention relates to the manufacturing equipment of the ink cartridge used in the inkjet recording equipment, in particular to a special device for filling the ink. Background technique [0002] In the manufacturing process of an ink cartridge for an inkjet recording device, a filling machine is generally used to fill the ink cartridge with ink. There are many types of filling machines, which are mainly divided into two categories: positive pressure filling and negative pressure filling from the working principle. [0003] In CN1371808A and CN1354089A two Chinese invention patent application publications, the applicant has provided multiple embodiments of positive pressure and negative pressure filling schemes, which are the same as the filling machines provided by other prior art. The technical requirement for quantitative filling of ink cartridges, or the use of quantitative pumps, or variable pumps, or the method of controlling cylinder...

Problems solved by technology

[0003] In CN1371808A and CN1354089A two Chinese invention patent application publications, the applicant has provided multiple embodiments of positive pressure and negative pressure filling schemes, the same as other filling machines provided by other prior art, in order to realize the The technical requirement for quantitative filling of ink cartridges, or the use of quantitative pumps, or variable pumps, or the method of controlling cylinder strokes, can achieve quantitative filling well, but the quantitative accuracy still cannot meet the ideal requirements, or The error value is still too large, and the existence of such an excessive error value directly affects the quality of the ink cartridge product

[0004] In the process from the ink source to the ink cartridge in the pipeline, the ink must pass through various electromagnetic valves that control the flow according to certain rules. The liquid is highly corrosive and rapidly damaged

In addition, when cleaning the inside of the ink pipeline of the filling machine, many solenoid valves on the ink pipeline must be disassembled one by one, which is not only complicated but also has a long cleaning cycle
