Abstract

The invention discloses a printer negative-pressure system and a control method thereof. The printer negative-pressure system comprises a plurality of ink boxes, a body for accommodating the ink boxes and a stirring apparatus, wherein the body is divided into an upper layer and a lower layer, the upper layer of the body is provided with a plurality of spaces for accommodating the ink boxes, the lower layer of the body is used for storing the stirring apparatus, the stirring apparatus comprises a motor, a stirring impeller and a control circuit board, the control circuit board is electrically connected with the motor, and the motor drives the stirring impeller to rotate. According to the invention, the impeller is arranged in the ink boxes, ink in a head ink box is stirred by driving the impeller to rotate, the ink is effectively dispersed, and precipitation is prevented. According to the technical scheme, the system and method overcome the problem of precipitation of the ink in an ink supply pipeline and the head ink box by use of a conventional method and guarantee the quality of ink-jet ink.

Description

technical field [0001] The invention relates to a printing device, in particular to a negative pressure system for a printing machine used in an inkjet 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 negative pressure sy...
