Ink path circulation system and control method of high-temperature glass ink-jet printer

Abstract

The invention provides an ink path circulation system and control method of a high-temperature glass ink-jet printer. An ink supply system of the ink-jet printer comprises main ink boxes, wherein themain ink boxes are connected with ink inlet boxes through first ink pumps and filters; the ink inlet boxes are connected with ink pumping boxes through ink nozzles; the ink pumping boxes are connectedwith the main ink boxes through second ink pumps, so that ink can flow back to the main ink boxes; the ink inlet boxes and the ink pumping boxes are correspondingly connected with negative-pressure controllers, so that the ink path circulation can be achieved; and the ink inlet boxes are further connected with ink pressing controllers, so that the ink nozzles can be fully filled with the ink. According to the ink supply system, the ink can continuously flow from beginning to end through the design of an ink supply path and the negative pressure effect; the deposition and clogging reduction effect can be achieved; and meanwhile, basic support can be provided for the good printing operation of the ink nozzles, thereby not only reducing the printing failure, but also prolonging the service life of ink path accessories and reducing the use cost.

Description

technical field [0001] The invention relates to a high-temperature glass ink-jet printer, in particular to an ink circulation system and a control method of the high-temperature glass ink-jet printer. Background technique [0002] At present, glass inkjet printers have been widely used in the field of glass production. The ink system of glass inkjet printers is one of the core components of glass inkjet printers. The ability of the printer to work continuously and stably. [0003] The ink used in glass inkjet printers has a large specificity and poor sedimentation resistance. Therefore, in the printing process, the ink needs to pass through a circulating ink system that prevents precipitation. The design of the ink system of the glass inkjet printer directly determines whether the ink output from the inkjet head is normal or not. The ink circulation system of the existing glass inkjet printer has a large ink impact and the ink supply is intermittent and frequent, which may...
