The support plate 2 rises to lift the container, and the weighing device 15 weighs the container, and the weighing data is fed back to the controller 1, and compared with the preset value of the controller 1 to distinguish, and after the container is weighed, the cylinder 14 The support plate 2 is driven down so that the container continues to be in contact with the roller 24, and the container continues to move with the movement of the roller 24 until it moves onto the qualified product roller 24. The position of the unqualified material is detected by the infrared sensor 8, and then the signal is transmitted to the controller 1, so that the controller 1 sends a command to control the electric push rod 10 to drive the push plate 9 to push the container into the slide plate 7 and slide into the collection tank 6. When the rejection component needs to be removed, by starting the motor 16, the motor 16 drives the bidirectional threaded rod 17 to rotate, so that the threaded seat 20 drives the clamping plate 19 to move outward, and the rejection component is disassembled.
