At present, the volumetric doser is a piece of mechanical equipment widely used by plastic machinery factories. It is also manufactured by the masterbatch machine manufacturer with excellent mechanical equipment and professional personnel.
It generally has data memory and storage functions, and it uses an AC brushless motor without maintenance. It is worth mentioning that the volumetric doser also adopts intelligent type control, intelligent and accurate calculation.
In addition, it can meet the requirements of external signal input. Its screw machine is treated with stainless steel plate, which is durable, and its modular installation structure is convenient and quick to disassemble, easy to remove and replace.
At present, the volumetric doser can be used for automatic mixing of new upgrade materials, secondary materials, masterbatches or additives.
The basic principle of the volumetric doser is that the data signal from the control box is transmitted to the motor, and the motor rotates slowly to promote the rotation of the screw extruder through the coupling. The plastic masterbatch in the hopper falls into the falling rod, is extruded by the screw extruder, and is transferred to the base by the screw, so as to ensure the purpose of accurate measurement, detection and transportation of the plastic masterbatch.
Immediate qualitative analysis of plastic masterbatches, additives or recycled materials, plus mixing, generally requires high-quality mixing quality and extremely high accuracy, so that it is possible to maintain the consistency of product color and quality.
There are two main ways to add plastic masterbatches, one is the rotary table type, and the accuracy is accurate, especially suitable for the production process with a small amount; the other is the screw type, which can be sustainable Add plastic masterbatch to the main raw material.
