Novel material supply mechanism

The utility model relates to the technical field of automatic control, in particular to a novel material supply mechanism. The problem that an existing supply mechanism is inconvenient to accurately detect the state of materials to be supplied is solved. The device comprises a machine body, a first rotating shaft, an air cylinder, a second rotating shaft, a detection spear, a third rotating shaft, a piston rod, a first proximity sensor, a second proximity sensor and a conveying channel, when the head of the detection spear is located at a first detection position, the tail of the detection spear is separated from the first proximity sensor and the second proximity sensor, and when the head of the detection spear is located at a second detection position, the piston rod is separated from the first proximity sensor. The tail of the detection spear covers the first proximity sensor and the second proximity sensor, and the width of the head of the detection spear corresponds to the size of the first proximity sen
