TECHNICAL FIELD

[0002] Color paste is a colorant widely used in the paint, ink, plastic and other industries, and in its production process, color powder needs to be uniformly added to solvents or base materials. However, the current color powder adding method has many problems. First, color powder usually has strong hydrophilicity and is prone to moisture absorption and clumping when stored in a humid environment. These clumps are difficult to disperse during stirring, affecting the quality and production efficiency of the color paste. In order to solve this problem, the existing technology usually needs to perform a pretreatment process such as re-screening and crushing on the color powder to ensure that the color powder can be smoothly mixed with other ingredients. These pretreatment processes not only increase the production cost, but also prolong the production cycle.

This not only causes material loss, but also can harm the environment and human health, leading to environmental pollution and raw material waste. Therefore, the utility model provides a feeding device for color paste production, which can automatically complete the screening and crushing of color powder and maintain the normal internal and external pressure of the feeder, facilitating dust collection and recycling, to simplify the production process, reduce dust pollution, and improve production efficiency and color paste quality.

[0020] In order to ensure that the toner block can be smoothly guided into the crushing part 4, in the embodiment, as a preferred technical scheme of the utility model, the first sieve plate 10 is inclinedly arranged, and the guide inlet 12 is arranged at the lowest end of the inclination of the first sieve plate 10.
[0021] In order to reduce the impact and wear of the first sieve plate 10 on the box 1 under the influence of the exciter 11, in the embodiment, as a preferred technical scheme of the utility model, the first sieve plate 10 edge is fixedly connected with rubber belt 15, and the first sieve plate 10 edge is fixedly connected with the inner wall of the box 1 through the rubber belt 15.
[0022] In order to support the first sieve plate 10 and improve the color powder screening efficiency, in the embodiment, as a preferred technical scheme of the utility model, the supporting assembly comprises supporting spring 16, the top end and the bottom end of the supporting spring 16 are fixedly provided with support 17, and the two supports 17 are fixed at the box wall of the box 1 and the bottom edge of the first sieve plate 10.
[0023] In order to facilitate the crushing of the color powder block, in the embodiment, as a preferred technical scheme of the utility model, the crushing mechanism comprises first rotating shaft 18, the shaft body of the first rotating shaft 18 is respectively welded with first spiral blade 19 and stirring blade 20, the edges of the first spiral blade 19 and the stirring blade 20 are respectively arranged on the surface of the second sieve plate 13, and the second sieve plate 13 is arranged in an arc shape.

[0025] Based on the technical scheme of the utility model, in the operation process, the color powder is lifted and conveyed to the box 1 storage part 2 through the vertical screw conveyor.
