The invention discloses an automation device vibrating disk capable of preventing shake-off of materials. The vibrating disk comprises a disk body, two ends of the top of the disk body are fixedly connected to two boxes, a bottom plate is arranged at the top of the disk body and positioned between the two boxes, a retaining fabric is arranged at the top of the bottom plate, a locking mechanism isarranged on the retaining fabric, the retaining fabric is fixed onto the bottom plate through the locking mechanism, moving mechanisms are arranged in the boxes and comprise two cross rods arranged inthe boxes, two ends of each box are fixedly connected with the side wall of the corresponding box, a lead screw is arranged between the two cross rods, two ends of the lead screw are rotatably connected with the cross rods, sliding rods are arranged in the boxes and positioned between the two cross rods, the two ends of each sliding rod are fixedly connected with T-shaped sliders, and T-shaped sliding grooves are formed in the opposite side walls of the boxes. According to the vibrating disk, the height of the retaining fabric can be suitably adjusted according to the number of the materialsin the vibrating disk, waste of the materials caused by shake-off of the materials is avoided, and the cost of a production enterprise is saved.
