Screw feeder is a common material conveying equipment, which is widely used in the automatic production line of industrial production. It is mainly composed of motor, screw, feed port, discharge port, transmission device support frame and other components. The following will be a detailed introduction to the internal structure of the screw feeder.
1. Motor: The motor of the screw feeder is one of its core components, which is mainly responsible for driving the rotary movement of the screw. The motor is usually mounted on one side of the screw feeder and is connected to the screw through a transmission device. The power of the motor depends on the use of the screw feeder, and the motor power required by different specifications of the screw feeder is also different.
2. Screw: The screw is the main working part of the screw feeding machine, and its internal structure is a spiral screw, which is generally composed of a spiral sheet and a shaft, and the spiral sheet is evenly distributed along the axis. The diameter and pitch of the screw determine the conveying capacity of the material, which is generally selected according to the characteristics of the material and production needs.
3. Feed port: The feed port of the screw feeder is usually located at one end of the screw and is used to put the material into the spiral chamber. The feed port is generally designed as an open port, and the appropriate feed port form can be selected according to the characteristics of the material, such as the circular feed port with a large diameter for granular materials, and the rectangular feed port for ribbon materials.
4. Discharge port: The discharge port of the screw feeder is usually located at the other end of the screw, which is used to discharge the material from the spiral chamber. The discharge port is generally designed with an opening, and the appropriate discharge port form can be selected according to the characteristics of the material, such as the circular discharge port with a larger diameter for granular materials, and the rectangular discharge port for ribbon materials.
5. Transmission device: Transmission device is an important part of the screw feeding machine, which is used to transmit the rotating motion of the motor to the screw. Common transmission devices include belt drive, chain drive and gear drive, etc., and the choice is determined according to the use needs and working environment of the screw feeder.
6 Support frame: The support frame is the bearing part of the screw feeder, responsible for supporting the weight of the entire equipment and maintaining its stability. The support frame is generally made of steel and has sufficient strength and stability to ensure that the screw feeder does not deform or shake during operation.
The internal structure of the screw feeder is compact and reasonable, and the various components are closely coordinated to achieve efficient conveying of materials. Through the motor to drive the rotating movement of the screw, the material enters the screw cavity from the feed port, and gradually moves to the discharge port with the push of the screw sheet, and finally discharge the screw feeding. machine has the characteristics of simple structure, easy operation, large conveying capacity, and is widely used in the production process of building materials, chemical industry, metallurgy, mining and other industries. Through reasonable design and selection of appropriate materials, the transportation needs of different materials can be met and production efficiency can be improved.
