Abstract

The invention relates to the technical field of printing, and discloses a printing device capable of preventing excessive ink from causing contamination and affecting printing quality. The printing device comprises an ink fountain, wherein an ink coating roller is movably connected to the right side in the ink fountain; an ink storage box is welded to the top of the ink fountain; a funnel groove is welded to the bottom of the ink storage box; and a hole blocking ball is movably connected to the interior of the funnel groove. According to the printing device capable of preventing the excessive ink from causing contamination and affecting the printing quality, when the ink is insufficient, the ink in the ink storage box can enter the ink fountain at the moment, when the ink is sufficient, ink adding can be automatically stopped, and therefore the effect that the usage amount of the ink is strictly controlled, and the printing quality is improved is achieved. When the ink amount is at the maximum value, ink adding is stopped, otherwise, when the ink content is normal, a swing rod can provide supporting force for a second sliding block at the moment, it is guaranteed that ink adding is started when the ink amount is at the minimum value, and therefore the effect that it is guaranteed that the ink content is within a reasonable range is achieved.

Description

technical field

[0001] The invention relates to the technical field of printing, in particular to a printing device that prevents the printing quality from being contaminated due to too much ink. Background technique

[0002] Printing is the process of transferring the approved printing plate to the substrate through printing machinery and special ink. According to the different printing materials used, printing is mainly divided into paper printing, white iron printing, plastic printing, textile printing, Woodblock printing, glass printing, etc., and the use of printing materials other than paper is called special printing.

[0003] Most of the printing devices use ink for printing. In the prior art, there is no strict control on the amount of ink used. Too much ink may contaminate other printed matter, and too little ink may cause unclear printing. Therefore, ink The amount used will seriously affect the quality of printing. How to strictly control the amount of ink used...
