Secondary ink box structure and printing device

Abstract

The invention discloses a secondary ink box structure and a printing device.The secondary ink box structure comprises an ink box body, a filter screen, an ink inlet connector, an ink outlet connector, a heating piece, a temperature sensor and a liquid level meter, and the ink box body is covered with a first cover plate and a second cover plate to form a sealed containing cavity; the filter screen is arranged in the accommodating cavity of the ink box main body so as to divide the accommodating cavity into a first accommodating cavity and a second accommodating cavity; the ink inlet connector is arranged on the ink box body so that ink can flow into the first containing cavity through the ink inlet connector. The ink outlet connector is arranged on the ink box body so that ink can flow out through the ink outlet connector after flowing into the second containing cavity. The heating sheet is arranged on the ink box main body so as to heat ink in the ink box; the temperature sensor is arranged on the ink box main body and is used for measuring the temperature of ink in the ink box; the liquid level meter is arranged on the ink box main body and is used for measuring the height of ink in the ink box; therefore, the pressure fluctuation of the ink in the ink box main body can be greatly reduced, and the printing quality is improved.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to a secondary ink box structure and a printing device. Background technique [0002] In practical applications, printing equipment is generally equipped with a secondary ink cartridge, which buffers ink and supplies ink to the print head stably. The existing printing equipment is carried out under the condition of high-speed paper feeding due to the inkjet code , so the ink is easy to fluctuate and cause pressure fluctuations, and if the pressure fluctuates greatly, the problem of ink leakage from the print head may occur, or the ink may be doped with air bubbles due to pressure fluctuations, which will cause air bubbles to be ejected from the nozzle holes that should be ejected instead of ejected. Ink is ejected, which affects print quality. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the above-mentioned technologies ...
