Ink supply circulation system capable of preventing ink from precipitating

Abstract

The invention discloses an ink supply circulation system capable of preventing ink from precipitating. The ink supply circulating system comprises an ink bin and an ink bag, wherein the ink bin is divided into a main bin area and an auxiliary bin area, the main bin area is communicated with the ink bag through a first circulating pipe, the ink bag is communicated with a B1 port end of a second circulating pipe, a first circulating pump is installed at the bottom of the ink bin, and the first circulating pump is provided with a B3 port end and communicated with the auxiliary bin area through a third circulating pipe; and a second circulating pump is fixed to the bottom of the ink bin, the second circulating pump is communicated with the main bin area through a fourth circulating pipe, the second circulating pump is communicated with the auxiliary bin area through a fifth circulating pipe, the fifth circulating pipe is provided with a C4 opening end, a motor, a long rod and stirring paddles are installed in the main bin area, and an air outlet and an air filter are arranged at the top of the auxiliary bin area. The ink in the ink bin and the ink bag can flow circularly through the double-circulation system; and the long rod and the stirring paddle are driven by the motor to rotate to evenly stir the ink in the main bin area, so that the ink can be effectively prevented from precipitating, and a nozzle is prevented from being blocked.

Description

technical field [0001] The invention relates to the technical field of inkjet ink, in particular to an ink supply circulation system for preventing ink from settling. Background technique [0002] In terms of pure cotton textile inkjet technology, more and more processes have turned to non-polluting water-based inks. However, the problem faced by water-based pigment inks is that too much or too little water-based permeation of pure cotton will cause the color to be not bright enough, and the amount used is large. Then In order to solve this problem, white ink was launched. [0003] Although white ink is worthy of recognition for the improvement of product quality, the inkjet maintenance of the machine used in production is indeed a lot of trouble. It is necessary to change the scraper, ink cup, and ink sac frequently. It is time-consuming and laborious to clean the ink tube and ink tank every week. The cleaning rate of the water-based dye-sublimation nozzle is 1.5 times hig...

[0003] Although white ink is worthy of recognition for the improvement of product quality, the inkjet maintenance of the machine used in production is indeed a lot of trouble. It is necessary to change the scraper, ink cup, and ink sac frequently. It is time-consuming and laborious to clean the ink tube and ink tank every week. The cleaning rate of the same water-based sublimation nozzle is 1.5 times higher, so that the nozzle is easy to block, which has a big impact on small and medium-sized enterprises
