How to achieve Plastic PVC mixing dosing conveying system to the sheet and profile extrusion production line?

What is Plastic PVC Mixing dosing conveying system?

The PVC metering, mixing and conveying system is a batching and mixing system specially used in the production process of PVC (polyvinyl chloride) materials. The system achieves high-precision proportioning and uniform mixing of PVC raw and auxiliary materials through precise metering and efficient mixing, thereby ensuring the quality and performance of PVC products.

Working principle of Plastic PVC mixing system?

In the PVC weighing and mixing system, the bulk raw materials such as PVC resin are first accurately metered and conveyed to the mixing unit through the main material feeding and weighing device. Then, various small component additives are accurately metered and added to the mixing unit in sequence through the auxiliary material micro-feeding and weighing device. In the mixing unit, the main material and auxiliary material are fully mixed through high-speed stirring and shearing to ensure the uniformity and stability of the mixture. Finally, the mixed materials are conveyed to the subsequent production process through the conveying system.

Process of PVC compounding mixer system?

1. Accurate metering of PVC compounding materials

During the PVC processing process, various additives such as heat stabilizers, lubricants, plasticizers and colorants are usually added to the PVC resin. The amount of these additives added needs to be precisely controlled to ensure the performance and quality of the final product. The PVC metering, mixing and conveying system adopts an advanced automatic weighing and metering system, which can achieve accurate metering of various additives with small errors and high precision, meeting the requirements of PVC batching process.

2. Mixing of PVC materials

Uniform mixing is a key link in the PVC processing process. The PVC metering, mixing and conveying system uses an automatic mixing device to fully mix various additives with PVC resin to ensure uniform mixing and sufficient absorption, thereby obtaining materials with accurate proportions and stable quality. This helps to improve the mechanical properties, heat resistance and aging resistance of PVC products.

3. Conveying of PVC materials

The PVC metering, mixing and conveying system not only achieves accurate metering and uniform mixing of the compounding materials, but also has efficient conveying capacity. The system uses pneumatic conveying, screw conveyor or pipe chain conveyor to convey the mixed PVC materials to production equipment such as extruders and injection molding machines. The conveying process is stable and reliable, avoiding waste and pollution of materials during the conveying process, while reducing the labor intensity of operators.

4. Automatic control

The PVC metering, mixing and conveying system adopts advanced automatic control technology to realize the automatic control of batching, mixing and conveying processes. Operators only need to monitor and operate in the central control room to realize remote control and adjustment of the entire system. This improves production efficiency, reduces labor costs, and ensures the stable operation of the system.
