volumetric doser is suitable for: injection molding machine, extruder or blow molding machine production;
Applied to: Automatic proportional mixing of new materials, secondary materials, color masterbatches or additives (PP materials, station-grade masterbatches), etc.
The volumetric doser machine PLC programming microcomputer color touch screen controller can measure the addition ratio of color masterbatch and additives. Applicable to various servo motors or stepper motors, the masterbatch machine controller can be connected with the signals of various molding machines, and then work synchronously to ensure the consistency of the performance of the molded products.
During work, it can be mixed according to the preset ratio, and the conditions set by the full digital microcomputer control system are automatically converted into rotational speed to directly drive the screw to extrude the raw material, and the error value is not higher than ±1%.
Volumetric doser working principle:
The signal from the controller (control box) is transmitted to the motor, and the motor starts to rotate, which drives the screw to rotate through the coupling; the color masterbatch in the hopper falls into the falling rod, is squeezed by the screw, and is transported to the base by the screw, thus achieving The purpose of metering and conveying color masterbatch.
Product features and advantages of volumetric doser:
1. PLC editing controller is adopted to intelligently measure the ratio and output of masterbatch additives;
2. It can realize the stable delivery of quantitative feeding and ensure the continuity of production of injection molding machine, extruder and film blowing machine;
3. It can run synchronously with the signals of various molding machines to ensure the consistency of the performance of the molding products;
4. It can meet the requirements of external signal input, has the function of formula storage and reading, and can quickly call and start the machine;
5. It can detect masterbatch blockage and overload, automatic shutdown protection and material shortage alarm function;
6. An optional agitator is available to meet the double mixing requirements of customers;
7 Modular assembly structure, which can quickly replace or clean the screw and sleeve, and has the function of forced cleaning, and the screw is chrome-plated;
8. The metering part can be removed from the base as a whole without material leakage. There are considerable material window devices on the side of the base and the hopper, which is easy to observe the raw materials;
9. It can hold 50-100KG dryer, if put 150-200KG dryer, it needs to be equipped with an enlarged base;
10. Applicable to: injection molding machine, extruder, film blowing machine mode; applied to: the proportion mixing of new, secondary materials, color masterbatch or additives, etc.;
11. Double screw volumetric doser can be selected according to the actual situation of customers.
Precautions before using the volumetric masterbatch doser:
When we use the volumetric doser, we must operate it correctly according to the product manual at the beginning, and we cannot do it arbitrarily, so as not to cause damage to the color doser and cause unnecessary losses, and it will not be too late to operate it by ourselves after a long time of use. Affect the use effect.
Doser installation matters:
The volumetric doser can be directly installed at the material inlet of the molding machine. In order to prevent the control box from shaking with the movement of the screw of the molding machine and related accessories from loosening, it is recommended to fix the control box on a certain bracket.
