The invention relates to the technical field of unpacking and unloading, and particularly discloses a full-automatic
powder bag stabbing and
cutting machine and a control method thereof. The full-automatic
powder bag stabbing and
cutting machine comprises a hoisting part, a
cutting tool part, a clamping plate part and a controller, and is characterized in that the hoisting part comprises a hoisting hook used for hoisting a bag opening, the hoisting hook is connected to a lifting plate, and the lifting plate is provided with a vibrator and is connected with a reel through a hoisting chain; the
cutting tool part comprises a
cutting tool directly facing the side face of a bag body, the
cutting tool is provided with an induction point and is installed on a fixing plate, a first sensor is installed beside a stabbing-in path of the cutting tool, and the fixing plate is connected with a first driving device; and the clamping plate part comprises clamping plates and second sensors, the clamping plates are symmetrically located on the two sides of a bag
tail, the second sensors are symmetrically located on the two sides of the bag
tail, and the clamping plates are connected with second driving devices correspondingly. Compared with the prior art, the structure is novel and simple, and design is reasonable; and due to the fact that the cutting tool capable of stabbing in and cutting the bag is designed, only the cutting function is achieved on the
powder packing bag, and no fragment is produced.
