Full-automatic silk-screen printing machine

Abstract

The invention relates to the technical field of printing equipment, and discloses a full-automatic silk-screen printing machine. The full-automatic silk-screen printing machine comprises a printing table. A printing and dyeing screen plate, a doctor blade and an inking knife are mounted at the upper end of the printing table, all of which can ascend and descend independently. An ink feed part usedfor intermittently and linearly releasing ink is mounted between the doctor blade and the inking knife. According to the full-automatic silk-screen printing machine, quantitative ink adding is carried out while the inking knife moves, ink is sealed all the time before being added, ink volatilization is reduced, the use dosage of ink additives is reduced, and the printing cost is reduced; in the printing process, the ink quality is stable, the mixed proportion of ink and additives is ensured through a flow control valve, meanwhile, ink is dynamically mixed in the flowing process, the automation degree is high, and manual participation is reduced; on one hand, ink is instantly prepared and instantly used, the containing time of prepared ink is greatly shortened, and volatilization is reduced; and on the other hand, the ink quality keeps consistent in the whole printing process.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to a fully automatic screen printing machine. Background technique [0002] The screen printing machine is a representative orifice plate printing equipment. When printing, ink is first poured into one side of the screen printing plate, then the ink coating plate moves to coat a layer of ink in the printing area, and finally the squeegee moves , to squeeze the ink from the mesh in the printing area to the substrate to complete a printing stroke. [0003] During this process, when the ink is exposed to an open or semi-closed state, volatile components such as diluents and solvents in the ink will volatilize. After a long time, the concentration of the ink will increase significantly. At this time, it is necessary to add diluents to The adjustment of ink concentration, on the one hand, will increase the use of ink and increase the cost. On the other hand, during the printing process...

Problems solved by technology

[0003] During this process, when the ink is exposed to an open or semi-closed state, volatile components such as diluents and solvents in the ink will volatilize. After a long time, the concentration of the ink will increase significantly. At this time, it is necessary to add diluents to Adjusting the ink concentration, on the one hand, will increase the use of ink and increase the cost; on the other hand, in the printing process, the ink concentration is changing, resulting in different quality of printed matter

[0004] Furthermore, since the ink diluent is volatile, it needs to be prepared on site. In actual printing, it is often changed to add ink while preparing the ink. Additional tools are required for stirring, vibration, etc., so that the diluent and ink are evenly mixed, adding additional workload, and the volatile thinner will also damage the health of the staff. On the other hand, the consistency of ink quality cannot be guaranteed
