Description

Technical Field

[0001] This utility model relates to the field of plastic processing equipment technology, and more specifically, to a feeding device for a plastic color powder machine. Background Technology

[0002] Plastic coloring is generally achieved by adding colored plastic granules during production. The coloring of plastic granules can be done by mixing and stirring a certain proportion of color powder with plastic granules according to the color specified by the customer using a plastic color mixing machine.

[0003] An automatic mixing and coloring machine for plastic granules, with Chinese patent publication number CN218019493U, includes a machine housing. A coloring device for injecting color powder into a mixing chamber is connected to the machine housing. The coloring device includes a powder storage box filled with color powder. A powder outlet trough is provided at the bottom of the powder storage box, with one side communicating with the mixing chamber. A feeding gear partially located in the mixing chamber is rotatably connected to the powder outlet trough. A feeding cavity is formed between the teeth of the feeding gear and the side wall of the powder outlet trough. The feeding gear is driven to rotate by a power device.

[0004] In the process of conveying powder from the powder storage box to the mixing chamber, the feeding gear in the mixing chamber of the above-mentioned patent may cause powder to stick together and get blocked between the feeding gear and the feeding chamber, resulting in low feeding speed and mixing efficiency. At the same time, the mixing component is too simple and has low mixing efficiency. The gate component is fixedly installed, making replacement, maintenance and cleaning very inconvenient.
