Product Description

Features:

* PLC control, touch screen display, and easy to operate and understand; * Modular assembly structure, convenient disassembly and assembly, easy to clean and exchange; * The standard base of the single-color doser is equipped with a hopper magnet to prevent damage to the screw rod of the molding machine; * The main hopper is the standard equipment of thedouble-color doser, and optional for the single-color doser; * Optional stirrer to break up additives with poor fluidity; * It meets the external signal input requirements, and records the current operation mode, and it is not affected by power failure, operating in the same mode after power restoration; * There are three feeding modes: gravimetric mode (this mode is of higher accuracy), volume mode, fixed ratio mode; * With weighing function, automatic calibration, and automatic monitoring of the addition of color master batch or additives; * With Ethernet communication function, data can be transmitted, and the amount of material recovered from the doser on the day can be recorded and stored; * It has the function of automatic color difference compensation, which can automatically adjust the proportion of color master batch or additives according to the proportion of recovered materials; * It uses the gravimetric weighing and measuring technology to control the mixing and dosing process, which can meet extremely high production accuracy requirements; * 50 groups of parameters, permanent recording of the discharge time and finished product weight (maximum output per minute for the extruder), and maintenance-free DC brushless motor; * Detection of color master batch blocking and overload, automatic shutdown for protection and alarm; * Based on the use conditions, set a certain number of mold cycles to add color master batch once to meet the micro-metering requirements.

Working principle:

* The signal from the control box is transmitted to the motor, and the motor starts operation to drive the screw rod to rotate through the coupling. * The color master batch in the hopper falls into the screw rod, and then is squeezed by the screw rod, and conveyed to the base by the screw rod. A weighing sensor is used to precisely control the output of the color master batch to realize the proportional addition of the color master batch, so as to achieve the purpose of accurately metering and conveying the color master batch.

Scope of application:

* Suitable for automatic proportioning and mixing of new materials, secondary materials, color master batches or additive materials; * With the screw diameter of 12mm, 16mm or 20mm, and four models that provide different output of 0.1-50kg/h; * Suitable for extruder and injection molding machine, only a little wiring is required for switching, and its rotation speed is automatically adjusted with the processing speed of the extruder to maintain a fixed color master batch ratio.
