In modern industrial production, material transportation and feeding is a crucial part of the production process. The traditional manual feeding method has low efficiency, high labor intensity, material loss and other problems, can not meet the needs of large-scale production. Automatic feeding machine as a kind of efficient, intelligent material conveying equipment, can realize the material automation, continuous and accurate feeding, greatly improve the production efficiency and the automation level of the production line. It is widely used in food, medicine, chemical, plastics, building materials and other industries, and has become one of the indispensable automation equipment in modern factories.

　　First, the working principle and structure of automatic feeding machine

　　1.Automatic feeding machine through the vacuum suction, screw conveyor or pneumatic conveying, etc., the material from the storage container or hopper automatically sucked or transported to the designated equipment (such as packaging machines, mixing machines, filling machines, etc.). The workflow is as follows:

　　Material sucking and conveying: the equipment will take out the material from the storage container or hopper through vacuum pump, screw conveyor or belt conveyor.

　　Material transfer: the material is continuously transported in the closed pipe or conveyor belt to prevent pollution and loss.

　　Automatic Measuring and Feeding: Automatic feeding machines are usually equipped with measuring and testing devices to ensure accurate material supply.

　　Automatic replenishment and cyclic feeding: when detecting the lack of material in the silo, the equipment automatically replenishes the material to ensure continuous production.

　　2. The automatic feeding machine is mainly composed of the following parts:

　　Feeding device: common ways include vacuum suction, screw conveyor, belt conveyor or pneumatic conveyor.

　　Hopper and piping system: the material is usually stainless steel or corrosion-resistant materials to prevent material contamination.

　　Electric control system: equipped with PLC control system and human-machine interface (HMI) to realize automatic control and parameter adjustment.

　　Detection and alarm system: with a lack of material alarm and automatic shutdown to prevent equipment idling or material waste.

　　Classification of automatic feeding machine

　　1. Vacuum feeding machine: use vacuum negative pressure to suck the materials from the silo into the conveying pipeline, and then convey them to the target equipment through the airflow. Suitable for powder, granule, flake material transportation. Commonly used in pharmaceutical, food and chemical industries.

　　2. Screw Feeder: Through the screw conveying structure, the material is pushed forward along the screw. Suitable for powder or granular material quantitative conveying. Widely used in food, feed and chemical industry.

　　3. Belt feeding machine: adopting belt conveying structure, it can realize large quantity material conveying. Suitable for bulk materials or large volume of granular material feeding. Commonly used in ore, grain and building materials industry.

　　4. Pneumatic feeding machine: the use of compressed air or fan power, the material will be transported through the pipeline. Suitable for lightweight granular or powder materials. Commonly used in plastics, chemical and pharmaceutical industries.

　　Third, the advantages of automatic feeding machine

　　1. Improve production efficiency, save labor costs: automatic feeding machine to achieve continuous automatic feeding, do not need frequent manual feeding. Alternative to manual handling, reduce labor costs and labor intensity. Feeding speed is fast and stable, conveying efficiency is 35 times higher than manual feeding.

　　2. Accurate feeding, less material waste: Equipped with measuring and detecting device, it can realize accurate material conveying and avoid waste. There is almost no loss or spillage of materials in the conveying process, which improves the production efficiency and yield rate.

　　3. Sealed conveying, environmental protection and no pollution: the equipment adopts sealed conveying structure, effectively preventing material leakage and dust pollution. It meets the GMP standard of food and pharmaceutical industry, ensuring clean production environment.

　　4. Intelligent control, convenient operation: the equipment is equipped with PLC control system and touch screen interface, easy to operate. It can realize automatic operation, lack of material alarm and automatic shutdown function, with high degree of intelligence. Remote monitoring and data recording, convenient for production management.

　　5. Strong compatibility, adapt to a variety of materials: the equipment can be adapted to a variety of specifications and forms of materials, such as powder, granules, flakes and so on. Flexible adjustment of conveying speed and conveying volume to meet different production requirements. Can be seamlessly connected with packaging machines, mixing machines, filling machines and other equipment to realize automated production lines.

　　Fourth, the main points of the purchase of automatic feeding machine

　　1. Material type and characteristics: according to the particle size, density and fluidity of the material to choose the appropriate feeding method (vacuum, spiral or belt).

　　2. Conveying capacity and capacity to match: to ensure that the equipment conveying speed and output to match the production requirements. Consider the conveying distance and height, choose the appropriate power configuration.

　　3. Automation and intelligent control: choose the equipment with PLC control and intelligent detection function, which is convenient for production management and maintenance.

　　4. Material and health standards: food and pharmaceutical industries need to choose 304 or 316L stainless steel to prevent material contamination. The equipment needs to comply with GMP or FDA standards.

　　With the advantages of high efficiency, precision, automation and environmental protection, automatic feeding machine has become an important equipment for modern industrial production line. It not only significantly improves production efficiency and reduces labor costs, but also ensures the precision and cleanliness of material conveying. With the continuous development of intelligent manufacturing and automation technology, automatic loading machine will play an important role in more areas, helping enterprises to achieve intelligent, efficient and green production.
