According to different needs and uses, plastic color powder can be divided into many types, such as UV stabilizer type, food grade type, etc. Plastic color powder needs to be added and stirred in the production process. In the process of plastic production and processing, plastic needs to be color-adjusted so that the plastic can be dyed with different colors to ensure the later production and processing of plastic products.

[0003] However, most of the toner processing mechanisms currently on the market generally have limited stirring efficiency. For example, the Chinese utility model patent application with patent announcement number CN221016295U discloses a production color mixing device, which includes: a color mixing tank, a color mixing cavity is provided in the color mixing tank, a plastic adding pipe and a toner processing mechanism are connected to the upper end of the color mixing tank, a stirring component is arranged in the color mixing cavity, a discharging component is connected to the middle of the lower end of the color mixing tank, and the toner processing mechanism includes a toner adding pipe connected to the color mixing tank, a motor A is connected to one side of the toner adding pipe, a rotating shaft A is connected to the output end of the motor A, a gear A is connected to the rotating shaft A, a gear B is meshed and connected to the gear B, a rotating shaft B is connected to one end of the gear B near the toner adding pipe, a crushing roller A is connected to the outer peripheral side of the rotating shaft A, a crushing roller B is connected to the outer peripheral side of the rotating shaft B, and a filter screen is connected to the lower end of the toner adding pipe.
