[0002] A feeder is a machine that uses the force of the machine's movement to apply force to the material and transport the material. Feeders are indispensable equipment for light and heavy industries. There are many types of feeders, which can achieve various types of conveying according to various application scenarios. Among them, the function of the layered lifting feeder is mainly to convey the materials to the compartments of different heights of the material rack in sequence.
