Premixing treatment method for ink production and preparation

Abstract

The invention relates to a premixing treatment method for ink production and preparation. Automatic mixing equipment is used in the method. The automatic mixing equipment comprises a stirring tank, astirring mechanism and a feeding mechanism, when the automatic mixing equipment is used for manufacturing printing ink, the specific method comprises the following steps of material proportioning, primary feeding, stirring, secondary feeding and discharging, the stirring mechanism comprises a stirring motor, a stirring shaft, a stirring frame, a first bevel gear, a second bevel gear and a supporting rod, and the feeding mechanism comprises a conveying pipe, a storage tank, a rotating plate, a guide hopper and an annular plate. The stirring mechanism and the feeding mechanism are jointly matched to complete the material mixing action, in the low-speed stirring process, the stirring mechanism can drive the feeding mechanism to add a small amount of materials into the stirring tank many times, the working intensity of the stirring mechanism can be relieved, and the stirring and mixing uniformity is improved.

Description

technical field [0001] The invention relates to the field of printing industry, in particular to a premixing treatment method for ink production and preparation. Background technique [0002] Ink is an important material for printing. It expresses patterns and characters on the substrate by printing or inkjet painting. The ink includes main components and auxiliary components, which are uniformly mixed and rolled repeatedly to form a viscous colloidal fluid, which is composed of binders, pigments, fillers, additives and solvents. [0003] The ink manufacturing process can be divided into two stages: stirring pre-dispersion and grinding fine dispersion. The former stirs the prepared pigment and linking material in the container to form a slurry; the latter still needs to be ground and finely dispersed in the stirred slurry, and the cohesion of the pigment is overcome by a large mechanical pressure and shearing force, and finally Become a suspended colloidal ink.

Problems solved by technology

[0005] (1) Generally, it is necessary to put the prepared materials into the mixer at one time for mixing in advance. During the mixing process, the working intensity of the mixer is high, and the resistance of the mixing blade is relatively large during the rotation process. After a long time of use, the mixing blade will inevitably break down. Damaged, it needs to be replaced from time to time, which increases the maintenance cost of the equipment;

[0006] (2) The installation position of the mixing blade is fixed, so during the mixing process, only the materials within a fixed range can be stirred, and it is difficult to ensure that all the materials in the mixer can be in contact with the mixing blade, and thus the uniformity of dispersion between the materials cannot be guaranteed. Affected the production quality of the ink
