Description

Technical Field

[0002] Toner, also known as carbon powder, is a powdered substance used in laser printers to form images on paper and is an indispensable part of using laser printers. Currently, there are more and more printers on the market and the demand for toner is also increasing. In response to different needs, toner production is developing towards refinement, colorization and high speed.

Since the installation position of the stirring rod in the stirring equipment is fixed, it can only stir and mix toner at the same height, and toner at different heights cannot be stirred and mixed well, which has a certain impact on the uniformity of toner mixing. Based on this, a mixing device for toner processing is proposed to solve the above problem. Utility Model Content
