Positive pressure and negative pressure circulation system used for printing head and capable of ensuring stable digital printing

Abstract

The invention discloses a positive pressure and negative pressure circulation system used for a printing head and capable of ensuring stable digital printing. The positive pressure and negative pressure circulation system used for the printing head and capable of ensuring stable digital printing comprises a main ink bucket, wherein an output end of the main ink bucket is unidirectionally connectedwith an input end of a main ink pump MYO; an output end of the main ink pump MYO is unidirectionally connected with an input end of a first two-way electromagnetic valve FYO; an output end of the first two-way electromagnetic valve FYO is unidirectionally connected with an input end of a first two-way electromagnetic valve MC; and an output end of the first two-way electromagnetic valve MC is unidirectionally connected with an input end of a buffer ink box S-X2. According to the positive pressure and negative pressure circulation system used for the printing head and capable of ensuring stable digital printing, the effect of storing ink is achieved through the arrangement for the main ink bucket; the effect of conveying ink is achieved through the main ink pump MYO; the effect of connecting with the first two-way electromagnetic valve MC is achieved through the first two-way electromagnetic valve FYO; and the effect of connecting with the buffer ink box S-X2 and 2.8kp liquid level S-X1 of a third rear ink box. The circulation system is stable in ink channel and free from the case of ink lack, and facilitates people to print an object.

Description

technical field [0001] The invention relates to the technical field of digital printers, in particular to a positive and negative pressure circulation system of a stable print head for digital printing. Background technique [0002] Digital printers, also known as universal flatbed printers and curved surface printers, can print soft and hard objects of any material and irregularity (requires that the drop of the surface should not exceed 7mm, otherwise the effect will not be good or even cannot be printed), and the digital printer can print high-quality colors on the surface of the material Image, without direct contact with the object, to ensure the integrity of the printed object, printing and dyeing through ink jetting, will not be deformed due to heat and pressure, using the direct output printing method of the computer, without any preparatory printing work in the early stage , while existing digital printers are prone to lack of ink when in use, which affects the qual...
