The working principle of the trough-type electromagnetic vibrating feeder is to utilize the periodic vibration generated by the electromagnetic vibrator to make the materials in the material trough be subjected to an inertial force perpendicular to the direction of gravity. When the inertial force on the material is greater than the friction force between the material and the material trough, the material will move forward in the material trough, thus achieving the purpose of feeding. During the vibration process, the material presents a jumping micro-throwing movement. This movement mode enables the material to be evenly distributed in the material trough and be transported forward at a stable speed.
Performance characteristics:
• Uniform feeding: It can transport materials uniformly and continuously to the receiving device, avoiding material accumulation and blockage, and ensuring the stability and continuity of the production process.
• Adjustable feeding amount: By changing the working parameters of the electromagnetic vibrator, stepless adjustment of the feeding amount can be easily realized to meet the requirements of different production processes.
• Simple structure: It is mainly composed of parts such as material trough, electromagnetic vibrator, vibration damping device and adjusting device. It has a compact structure, small volume, light weight, and is convenient for installation and maintenance.
• Reliable operation: There are no rotating parts, and there are no mechanical wear and lubrication problems, reducing the failure rate of the equipment and improving the service life of the equipment. At the same time, the working stability of the electromagnetic vibrator is high and it can operate stably for a long time in harsh working environments.
• Low energy consumption: Due to the adoption of the electromagnetic vibration principle, the equipment consumes less electric energy during operation and has a good energy-saving effect.
• Low noise: The noise generated during the operation of the equipment is small, which has little impact on the surrounding environment and improves the environmental conditions of the workplace.
Application fields:
