The invention provides unqualified material elimination equipment for a production line. The unqualified material elimination equipment comprises an elimination machine main body, a protection cover,a gear, a micro-motor, a fixed rack, a glass window, a storage box, a vibration absorption cushion, a fixed plate, a magnet block I and a magnet block II, wherein the protection cover is mounted on anupper end surface of a control panel; the gear is mounted in the protection cover; the micro-motor is mounted on the right end surface of the gear; the fixed rack is mounted at the left side of the control panel; the glass window is arranged in the front end surface of the protection cover. By adopting the design, the problem that a dust prevention structure of an original elimination machine isnot sufficient enough is solved; the storage box is mounted on the front end surface of the fixed plate and the vibration absorption cushion is mounted in the storage box; the fixed plate is fixed onthe front end surface of a worktable through welding; the magnet block I is mounted on the lower end surface of the storage box; the magnet block II is mounted on the lower end surface of the magnet block I. By adopting the design provided by the invention, the problem that the original elimination machine is not convenient to store is solved; the unqualified material elimination equipment has theadvantages of reasonable structure, convenience for storage, high dust-prevention effect and high reliability.
