Problems solved by technology

This technical solution has strict requirements on the viscosity of the material during grinding, and the viscosity needs to be controlled at 50-250cps, and the dispersant needs to be added in batches, resulting in a complicated process and a large workload; in addition, it is necessary to add an ultrasonic generator, which is easy to produce The heat will significantly increase the temperature of the color paste and the temperature of the equipment during the grinding process, which will increase the difficulty of heat dissipation and increase the cost. The noise in the production process is large, and it is difficult to ensure stable product quality.

Description

technical field [0001] The invention relates to a grinding device, in particular to a grinding device applicable to grinding heat transfer color paste; the invention also relates to a grinding process of heat transfer color paste. Background technique [0002] At present, the grinding equipment in the field of thermal transfer printing paste mainly adopts vertical grinding equipment or horizontal grinding equipment. The existing vertical grinding equipment has gradually exposed some shortcomings in the process of use, such as intermittent production, high energy consumption, more labor, relatively low grinding efficiency, high requirements on the site, etc. It is difficult to meet the rapid growth of thermal transfer ink sales. . Although the horizontal grinding equipment does not have high requirements on the site, the grinding beads in the grinding barrel have poor reciprocating motion and friction and impact capabilities between the beads, resulting in low grinding effic...
