Abstract

The invention discloses a jetting head negative-pressure system for an ink-jet printer, and a control method thereof. The jetting head negative-pressure system comprises a plurality of ink boxes, a body used for receiving the ink boxes, and a stirring device, wherein the body is divided into an upper layer and a lower layer; a plurality of spaces used for receiving the ink boxes is formed in the upper layer of the body, and the lower layer of the body is used for storing the stirring device; the stirring device comprises a motor, stirring impellers and a control circuit board; the control circuit board is electrically connected with the motor; and the motor drives the stirring impellers to rotate. According to the jetting head negative-pressure system disclosed by the invention, the impellers are arranged in the ink boxes and driven to rotate to stir ink in the ink boxes, so that effective dispersion for the ink is realized, and precipitates are prevented. The technical scheme provided by the invention overcomes the problem of precipitates of ink in an ink supply pipeline and a head ink box in a traditional method, and ensures the quality of the ink-jet ink.

Description

technical field [0001] The invention relates to a printing device, in particular to an ink-jet printer nozzle negative pressure system used for the ink-jet printer. Background technique [0002] Rigid printed circuit boards have high requirements for ink dispersion and particle size, but the nature of the ink itself is relatively easy to cause precipitation, clogging pipelines and nozzles. Therefore, effective prevention of ink deposition is an essential part of rigid printed circuit board printing equipment. [0003] At present, the method of preventing ink precipitation in rigid printed circuit board printing equipment is realized by the oscillation function of the first-level ink bottle. When the ink stays in the head ink tank for a long time, it is easy to produce precipitation in the pipeline, especially in the head ink tank. Directly affect the printing effect. Contents of the invention [0004] The purpose of the present invention is to provide a nozzle negative ...
