Problems solved by technology

Since the ink is a viscous substance, it will settle if it is left standing for a long time, so that the concentration of the ink at the bottom will gradually increase, and the fluidity of the ink will decrease, which is not conducive to the atomization of the ink nozzle; and the ink will settle. , leading to an increase in the concentration of the ink at the bottom, which increases the viscosity of the ink and is prone to short-ink phenomenon
In addition, ink layering will lead to uneven concentration of ink, which will make the color of the same ink ejected at different times inconsistent, affecting printing quality

Embodiment Construction

[0016] The following is further described in detail through specific implementation methods:

[0017] The reference signs in the accompanying drawings of the description include: ink tank 10, stirring shaft 20, stirring blade 21, ink channel 22, mesh plate 30, rubber bag 31, liquid inlet check valve 32, liquid discharge check valve 33, cylinder Body 40, piston 41, intake check valve 42, exhaust check valve 43, elbow 50, exhaust pipe 51, nozzle 52.

[0018] The embodiment is basically as attached figure 1 , figure 2 Shown:

[0019] The color printing ink supply device includes an ink tank 10, an agitating shaft 20 and a motor. The agitating shaft 20 is driven to rotate by the motor. The agitating shaft 20 penetrates the ink tank 10 and extends downward in the vertical direction. The upper end is connected to drive the stirring shaft 20 to rotate. The upper end of stirring shaft 20 is provided with stirring blade 21 and net plate 30, and stirring blade 21 is positioned at t...

Abstract

The invention relates to the technical field of printing, and particularly discloses a color printing printing ink supply device. The color printing printing ink supply device comprises a printing inkbox body and a stirring shaft. The stirring shaft penetrates through the printing ink box body, and stirring blades located in the printing ink box body are arranged on the stirring shaft. A cylinderbody is arranged below the printing ink box body, a piston only capable of sliding in the vertical direction is arranged in the cylinder body, and a cylindrical cam structure is formed by the stirring shaft and the piston. An air inflow one-way valve and an air exhaust one-way valve are arranged on the cylinder body, and an air exhaust port of the air exhaust one-way valve is communicated with the bottom of the printing ink box body. A mesh plate located below the stirring blades is arranged in the printing ink box body, the stirring shaft penetrates through the mesh plate, and the mesh platecan slide up and down relative to the stirring shaft. A printing ink passageway is formed in the stirring shaft, and the lower end of the printing ink passageway is communicated with a spray nozzle.A rubber bag communicated with the printing ink passageway is arranged below the stirring blades, the mesh plate moves up and down to extrude the rubber bag, a liquid drainage one-way valve is arranged in the printing ink passageway, a liquid inflow one-way valve is arranged on the side wall of the stirring shaft, and the concentration of printing ink can be uniform under the effects of stirring of the stirring blades and bubbles.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to a color printing ink supply device. Background technique [0002] On the color printing equipment, the ink is stored in the box, and the ink nozzle is set at the bottom of the box, and the ink in the box is sprayed onto the rubber roller or the printing plate through the ink nozzle. Since the ink is a viscous substance, it will settle if it is left standing for a long time, so that the concentration of the ink at the bottom will gradually increase, and the fluidity of the ink will decrease, which is not conducive to the atomization of the ink nozzle; and the ink will settle. , leading to an increase in the concentration of the ink at the bottom, which increases the viscosity of the ink and is prone to short-ink phenomenon. In addition, ink delamination will lead to uneven ink concentration, which will cause inconsistent colors of the same ink ejected at different times and affe...
