In modern industrial production, especially in the processing of polymer materials such as rubber and plastic, the vacuum feeding, automatic batching, high-speed mixing, and metering and conveying systems of the internal mixer constitute the core links of efficient and precise production. These systems cooperate with each other, from material conveying, proportioning, mixing to final conveying, each step is carefully designed, greatly improving production efficiency and product quality. The following will provide a detailed introduction to these systems.

Vacuum feeding system for internal mixer

The vacuum feeding system of the internal mixer is the starting point of the entire production process, responsible for the important task of safely and efficiently transporting materials to the internal mixer. The system mainly operates based on the principle of vacuum negative pressure, generating negative pressure through a vacuum pump, forming an airflow in the pipeline, sucking materials from storage bins and other positions into the conveying pipeline, and finally conveying them to the feed inlet of the internal mixer.

The vacuum feeding system has many significant advantages. Firstly, it can achieve closed conveying of materials, effectively avoiding pollution, moisture and other problems caused by contact with the external environment during the conveying process, ensuring the stability of material quality; Secondly, the system can achieve long-distance and high-altitude transportation, suitable for various complex production layouts; Thirdly, it has a high degree of automation and can seamlessly integrate with production control systems, automatically starting and stopping according to production needs, reducing manual intervention, labor intensity, and labor costs. In addition, the vacuum feeding system also has good explosion-proof performance, which can effectively ensure production safety for the transportation of some flammable and explosive materials.

Automatic batching system

The automatic batching system is the key to ensuring product quality consistency. It uses advanced sensors, controllers, and actuators to accurately weigh and ratio various materials according to preset formulas. The system first detects the weight of the material in real time through a weighing sensor, and feeds back the data to the control system. The control system then controls the conveying equipment of each material (such as screw conveyors, belt scales, etc.) according to the preset formula instructions, accurately controlling the conveying amount of the material and achieving precise batching.

The advantage of an automatic batching system lies in its extremely high batching accuracy, which can control errors within a very small range and ensure the stability of product quality. At the same time, the system can store multiple formulas, making it easy to quickly switch between different products during production, greatly improving the flexibility of production. In addition, the automatic batching system can also monitor and record data in real-time during the batching process, facilitating quality traceability and production management, effectively improving the management level and production efficiency of enterprises.

High speed hybrid system

A high-speed mixing system is an important equipment that thoroughly mixes the prepared materials to achieve uniform dispersion. The system mainly consists of a mixing container, a stirring blade, a driving device, and a heating/cooling system. During the working process, the high-speed rotating stirring blade generates strong convection, shear, and diffusion movements of materials in the container, achieving rapid mixing of materials. Meanwhile, through heating or cooling systems, the temperature during the mixing process can be adjusted to meet the mixing process requirements of different materials.

The characteristics of high-speed hybrid systems are high mixing efficiency and good mixing uniformity. It can fully mix various materials with different properties in a short period of time, forming a uniform mixture and providing a good foundation for subsequent processing procedures. In addition, the system also has a certain plasticizing function. For some plastic materials, they can be initially plasticized during the mixing process to improve processing performance. Moreover, the high-speed hybrid system is easy to operate and maintain, and can adapt to production needs of different scales.

Measurement and conveying system

The metering and conveying system is an important guarantee for accurately conveying mixed materials to the next process according to production requirements. It accurately measures the flow rate or weight of materials through measuring devices such as rotor scales, mass flow meters, etc., and controls the conveying equipment (such as belt conveyors, pneumatic conveying devices, etc.) according to the production rhythm to stably and accurately transport materials to designated positions.

The accuracy of the measuring and conveying system ensures a stable supply of materials during the production process, avoiding problems that may affect product quality and production efficiency due to fluctuations in material conveying volume. At the same time, the system can select suitable conveying methods and measuring devices according to different material characteristics and production process requirements, and has strong adaptability. In addition, the metering and conveying system can also be linked and controlled with other production systems to achieve automation and intelligence of the entire production process, improving the precision of production management.

The vacuum feeding, automatic batching, high-speed mixing, and metering conveying system of the internal mixer play an indispensable role in modern industrial production. They each have unique functions and advantages, cooperate with each other, and jointly build an efficient, accurate, and stable production system, providing strong support for enterprises to improve product quality, increase production efficiency, and reduce production costs, and promoting the continuous development of related industries towards automation and intelligence.
