Abstract

The invention provides a method for making a liquid ink gun, the liquid ink gun and printing equipment. The method comprises the steps that a pressure generating component is formed on a base; a pressure chamber and a common chamber are formed on the first surface of the base; the surfaces, away from the base, of the pressure chamber and the common chamber are coated with first resin adhesives, and spray hole adhesive layers are formed; gray exposure treatment is carried out on the spray hole adhesive layers so that conical spray holes can be formed in the positions, corresponding to the pressure chamber, of the spray hole adhesive layers, and the cross section area of the spray holes is gradually reduced in the direction away from the pressure chamber. According to the method for making the liquid ink gun, the liquid ink gun and the printing equipment, the problem that the jet precision of an existing liquid ink gun is poor can be solved so as to improve printing speed and printing precision, the problem that printing quality is lowered due to the fact that the adhesives are adopted can be avoided, and the mechanical strength of the pressure chamber can be improved.

Description
