The volumetric doser is based on the principle of screw volumetric metering, and is specially designed for the application process of color masterbatch metering and adding in injection molding equipment. Suitable for plastic molding industry.
The work of the volumetric doser is to work synchronously according to the melting time of the injection molding machine. It is only necessary to connect the melting signal of the injection molding machine to the lead wire of the electric control box. The melting signal is transmitted to the electric control box and then to the motor, and the motor starts When it is running, the screw is driven by the coupling, and when it rotates, the color masterbatch in the hopper falls into the screw, is squeezed by the screw, and is transported to the base by the screw, so as to achieve the purpose of metering and conveying the color masterbatch.
The volumetric doser adopts DC brushless motor, which has long-term memory and storage function of data. Modular assembly structure, easy to disassemble, easy to clean and replace. A stirring base is optional to ensure that the materials are mixed evenly; it can be accelerated and decelerated synchronously with the main screw of the extrusion (calender) machine.
If the weight does not meet the requirements, the weighing regulator can adjust the opening of the gate according to the signal from the sensor, and adjust the weight of the material on the weighing platform by controlling the displacement of the weighing platform to ensure that the weight of the material to be weighed is stable within a certain range.
