External agent introducing and adding device for printing

Abstract

The invention discloses an external agent introducing and adding device for printing. The device mainly comprises a weighing hopper and an external additive hopper, wherein the external additive hoppers are arranged right above the weighing hopper at intervals; the weighing hopper is fixedly welded on the weighing hopper support frame; the external additive hopper is hoisted on the external additive hopper supporting frame through a hoisting rod; according to the invention, in the actual mixing process, the metering pump is used for realizing quantity control; meanwhile, the three-way electromagnetic valve is used for adjustably conveying water to the weighing hopper and the auxiliary water tank; the printing ink stock solution fed into the weighing hopper is mixed with the external agentand then fed into the stirrer; and water in the auxiliary water tank is sprayed out from the spray head under the pressurization conveying effect of the booster pump, and at the moment, the inner wallof the weighing hopper is flushed, so that the situation that an external agent is attached and wasted can be avoided, effective waste prevention can be realized by integrally adopting single water injection, the effect is excellent, and the operation is simple and easy.

Description

technical field [0001] The invention relates to the field of printing equipment, in particular to a device for introducing and adding external agents for printing. Background technique [0002] In the process of printing ink preparation, a small amount of external agent needs to be added to achieve better use effect. However, due to the small amount of external agent added, it is easy to cause pipeline residues. Therefore, in most cases, the external agent is mixed with the ink stock solution in advance, and then added. , there is still some loss in this way. SUMMARY OF THE INVENTION [0003] In order to overcome the above-mentioned shortcomings, the present invention aims to provide a technical solution that can solve the above-mentioned problems. [0004] An external agent introduction and addition device for printing mainly includes a weighing hopper and an external additive hopper, wherein the external additive hopper is spaced at a position just above the weighing ho...
