  About the introduction of plastic dosing unit equipment

Principle of plastic dosing unit

Input the color masterbatch or plastic raw materials into the hopper of the plastic dosing unit, and then set the parameters, and set the feeding parameters of each color masterbatch to perform automatic weighing. After weighing, the hopper discharge valve automatically opens, and the raw materials enter the mixing tank after weighing. Stir
Modular and detachable structure design, saving space and easy to clean;
Use universal PLC controller to ensure reliable performance and easy maintenance;
Adopt advanced control algorithm, independent optimization, automatic adjustment compensation and vibration prevention functions to ensure the best batching accuracy;
The standard model can handle up to four components (more than six components can be customized);
Color graphic display, touch screen operation, multiple languages ​​for selection;
With formula storage function, it can store more than 100 groups of formulas at most;
Hierarchical security password control and alarm history record function;
The controller is equipped with a standard USB2.0 interface, which can save the mixing ratio data to the U disk, which is convenient for production quality control;
With sound and light alarms, it is convenient for the equipment personnel to quickly and accurately reach the faulty machine site;
All parts in contact with raw materials are made of stainless steel to prevent raw materials from being contaminated;
It can be installed directly on the machine or with an optional tripod installed next to the machine (including pneumatic discharge valve).
Optional components
Hopper low material level alarm switch;
Suction control 1/0 module;
Pneumatic discharge valve (used to directly install the platform or shelf above the machine);
Tripod, pneumatic discharge valve, storage bucket and suction box (for tripod mounting type);
Ethernet interface, MODBUS, PROFIBUS communication module can realize remote monitoring and data exchange with extruder, injection molding machine and other hosts.

Application of plastic dosing unit


This is an automatic weighing and mixing device dedicated to medical or environmental protection products. It is made of sealed food grade stainless steel. Automatic weighing, automatic measurement and automatic mixing of granular or powder granular raw materials, with high accuracy.
Note: 1 The mixing ratio error refers to the difference between the set percentage and the actual percentage of each component;
2. The standard valve is not suitable for powder measurement.

3. The above is based on large processing capacity and mixing ratio error data based on quasi-density 0.8mg/L, diameter 3-4mm, the data will vary according to the characteristics of the raw materials, if you use uncertain materials, please discuss separately, it is 3-4mm The uniformity of the particles is the data obtained by continuous transportation.
It can mix 1 kind of pellet, 2 kinds of granules, 3 kinds of color masterbatches granules, 4 kinds of resin particles, 5 kinds of plastic pellets, 6 kinds of powders, 7 kinds of color masterbatches, and more plastic granules. For example: POM, ABS, TPE, PAL, ABS, CAB, EVA (2), EVOH, LM (4), LCP, PA11, PA6.46.6, PAI, PAR, PBT, PC,PC/ABS,PC/PBT,PE.HDEPE,LDPE black3%,PE.HDEPE.LDPE black40%,PEEK,PE(1), PEN,PES,PET,PETG,PI,PMMA,POM,PP,PPO,PPS,PS,[GPPS.EPS.HIPS],PSU,PIT,PUR, PVC, SAN, SB, TPE, TPE, TPO, TPU, and other plastic granular resin materials or powder color masterbatches

Operation Guide for plastic dosing unit

1. The plastic dosing unitis operated according to the specified method. Those who are not trained or familiar with the operator are strictly prohibited from using the color mixer without authorization.
2. Regularly refuel the bearings and gears of the machine.
3. When the machine is running, it is strictly forbidden to reach inside or rotate parts.
4. The power must be turned off during cleaning or maintenance.
5. It is strictly forbidden to exceed the rated weight (100KG), and the dust and impurities in the hopper must be cleaned before mixing.
6. Jog before color mixing to ensure that it is turned on and used under no abnormal conditions.
7. Turn off the power after color mixing.
8. Keep the machine clean in each shift, and maintain the machine every day. It is strictly forbidden to place other sundries around the color mixing machine. Keep the inside and outside of the box clean.
