摘要:Central feeding system,Extrusion Central Feeding System

Extrusion Central Feeding System以下是關(guān)于擠出中央供料系統(tǒng)(Extrusion Central Feeding System)的英語(yǔ)介紹: An extrusion central feeding system is a crucial facility in the extrusion process of the plastics industry. It is mainly used to supply various raw materials to the extruder in a centralized, automatic and efficient manner. Here is a detailed introduction: ### Working Principle - The system utilizes a combination of vacuum and pneumatic conveying principles. Raw materials stored in silos are first sucked into the conveying pipeline by vacuum pumps. Then, under the action of compressed air, they are transported along the pipeline to the central drying and mixing unit. After being dried and mixed evenly, the materials are sent to each extruder according to the production requirements. This ensures a continuous and stable supply of materials, improving production efficiency and product quality. ### Components - **Storage Silos**: These are used to store various raw materials, such as plastic pellets, additives, etc. They are usually made of stainless steel or other corrosion-resistant materials to ensure the quality of the stored materials. - **Vacuum Pump Unit**: It creates a vacuum environment in the conveying pipeline to suck the raw materials into the system. It consists of a vacuum pump, vacuum valves, and related pipelines. - **Pneumatic Conveying System**: Driven by compressed air, it transports the materials in the pipeline. It includes air compressors, air filters, pneumatic valves and pipelines. - **Central Drying and Mixing Unit**: This unit dries the raw materials to remove moisture and mixes different raw materials in a precise ratio. It usually contains a dryer, a mixer, and related control devices. - **Distribution System**: It distributes the dried and mixed materials to each extruder. It includes distribution valves, branch pipelines and flow meters to accurately control the amount of materials supplied to each extruder. - **Control System**: Composed of a programmable logic controller (PLC) and a human-machine interface (HMI), the control system enables operators to set and monitor various parameters of the system, such as material conveying speed, drying temperature, mixing ratio, etc. It also has functions such as fault diagnosis and alarm. ### Advantages - **High Efficiency**: It can supply raw materials to multiple extruders simultaneously, significantly increasing production efficiency and reducing labor costs. The automatic operation mode reduces the time and effort required for manual material handling. - **Stable Quality**: The precise control of the drying and mixing process ensures the stability of the material quality, which is beneficial to improving the consistency and quality of the extruded products. - **Flexibility**: It can easily adapt to different production requirements by adjusting parameters such as the type of raw materials, mixing ratio and conveying speed. It is suitable for the production of various plastic products with different specifications and requirements. - **Clean and Environmentally Friendly**: The closed conveying system reduces dust emissions and raw material waste, keeping the production workshop clean and reducing environmental pollution. In conclusion, the extrusion central feeding system plays an important role in improving the efficiency and quality of plastic extrusion production, and is an essential part of modern plastic processing enterprises.

Central feeding system usually denotes a central material supply system designed for the production of plastic products in injection molding workshops. The following presents a detailed account: ### General Introduction It is also known as a centralized material supply system or an automatic material delivery system. It realizes continuous unmanned molding operations, and can change the types of raw materials and the combination modes of multi-color materials as needed, thus automating the coloring process. ### Working Principle The system uses a vacuum transmission method. It transports plastic raw materials from storage tanks to a central dehumidification and drying system through a centralized pipeline system, and then delivers the dried materials to each injection molding machine. It adopts the "one machine, one pipe" design to ensure that the air in the whole system transports the materials, preventing the dehumidified and dried materials from absorbing moisture again. After each conveying cycle, the system cleans the pipeline to ensure there are no remaining pellets. Moreover, under the action of vacuum negative pressure, the dust in the raw materials is filtered out by the dust filtration system. ### Components 1. **Central Control Console**: Usually uses PLC and a large-color human-machine interface touch panel, which is easy to understand and operate. It can display various settings and operating conditions, and has functions such as material pipe evacuation and cleaning, automatic dust collection, and anti-misoperation for manual material selection. 2. **Cyclone Dust Collector**: Integrates the air filter and cyclone dust collector, using natural centrifugal force to efficiently collect dust. It can be equipped with a high-pressure air storage tank for automatic filter cleaning. 3. **High-Efficiency Filter**: Filters out dust and tiny impurities in raw materials, effectively protecting the blower and extending its service life. 4. **Blower**: Provides power for the vacuum transmission of materials.
