Problems solved by technology

[0003] In actual use, due to the continuous improvement of design concepts and environmental protection awareness, in order to reduce the exposure and volatilization during the use of inkjet printers, the entire ink system is often sealed as much as possible, and the air sealed in the ink cartridge will be difficult to communicate with the environment temperature The external atmospheric pressure reaches a natural balance. When the ambient temperature rises or the external air pressure decreases, the air enclosed in the ink tank will expand; conversely, when the ambient temperature decreases or the external air pressure becomes high, the air enclosed in the ink tank will contract. , which will lead to dangerous accidents such as deformation or even explosion of the ink cartridge, and will also affect the smoothness and stability of the printing process of the inkjet printer

Embodiment 1

[0037] An air pressure balance device for an ink cartridge of an inkjet printer, comprising a buffer chamber C and an ink cartridge A. An ink outlet is provided at the bottom of the ink cartridge A, and the ink outlet is sealed by a solid rubber plug B. The buffer cabin C includes a buffer cabin main body, an exhaust pipe 3 , a balance pipe 4 and an extraction pipe 5 , and the buffer cabin C main body is a closed container. One end of the balance tube 4 leads into the bottom of the inner cavity of the buffer chamber C, and the other end is integrally connected with the stainless steel fine needle tube 1 to form a connected body between the buffer chamber C and the ink cartridge A. One end of the exhaust pipe 3 communicates with the top of the inner cavity of the buffer cabin C, and the other end is provided with a normally open valve V1. The chamber pressure is in balance with the external atmospheric pressure. That is, when the normally open valve V1 is de-energized, the con...

Embodiment 2

[0041] In this embodiment, the ink cartridge A is used to contain the solvent used for cleaning the pipeline, so it is called solvent cartridge A in this embodiment. It includes a buffer cabin C and a solvent box A. A solvent outlet is provided at the bottom of the solvent box A, and the solvent outlet is sealed by a solid rubber plug B. The buffer cabin C includes a buffer cabin main body, an exhaust pipe 3 , a balance pipe 4 , an extraction pipe 5 and a solvent extraction pipe 6 , and the main body of the buffer cabin C is a closed container. One end of the balance tube 4 leads to the bottom of the inner cavity of the buffer cabin C, and the other end is integrally connected with the stainless steel fine needle tube 1 to form a connected body between the buffer cabin C and the solvent box A. One end of the exhaust pipe 3 communicates with the top of the inner cavity of the buffer cabin C, and the other end is provided with a normally open valve V1. The chamber pressure is i...

Abstract

The invention discloses an ink-jet printing machine ink box air pressure balancing device and method. The device comprises a closed solvent box and a buffering bin. The closed solvent box and the buffering bin are connected through a balance pipe to form a communication body. The buffering bin communicates with an ink pipeline system of an ink-jet printing machine through an extraction pipe. The ink-jet printing machine ink box air pressure balancing device and method have the beneficial effects that on the basis of the device, natural balance can be achieved between air closed in the ink box in a jet printing machine system and the outer barometric pressure, the situation that due to the environment temperature change, the inner pressure intensity and the outer pressure intensity of the closed space change, consequently the closed solvent box deforms, and even dangerous accidents happen is avoided, and the using convenience of the ink-jet printing machine and the production continuous stability are further greatly improved.

Description

technical field [0001] The invention relates to the technical field of inkjet printing equipment, in particular to an air pressure balancing device and method for an ink cartridge of an inkjet printer. Background technique [0002] The working mechanism of the continuous ink jet printer is to control the voltage on the charging electrode through the CPU, and use the principle of electrostatic induction to indirectly control the amount of charge of the ink dots ejected from the nozzle. When ink dots with different charges pass through the high-voltage electrostatic field, they are Different Coulomb force, there will be different deflection, so as to realize the landing of different ink dots at different positions on the surface of the front object to form the printing content; the ink drop with zero charge does not deflect, and is directly injected into the front of the nozzle. The recovery tube at the front end is recycled and recycled. Due to volatilization, the viscosity o...
