[0002] The granulated materials in drug production are transported from the material warehouse to the workshop every day. The granulated materials are packaged in outer bags of the granulated materials and are transported into the laminar flow control area through the conveying system; then, they are grabbed by the manipulator to the position of the bag opening device for bag opening, and the granulated material unpacking operation is completed in the clean area, and the granulated materials are put into the suction hopper. Finally, the waste bags are automatically collected, so as to realize the full automation operation of palletizing and bag opening.

[0003] However, the existing bag opening method is to open the bag with a serrated cutter.

The blade is driven by the power translation mechanism I to translate in a direction parallel to the blade for bag opening. The power translation mechanism II pushes the blade to translate in a direction perpendicular to the blade to the bag opening position;

[0006] The chip suction device includes a chip suction box arranged parallel to the direction of the blade translating for bag opening, a chip suction pipeline communicated with the chip suction box, a plastic chip collection box communicated with the chip suction pipeline, a suction fan communicated with the plastic chip collection box, and a power translation mechanism III for driving the chip suction box to translate in a direction perpendicular to the blade. The power translation mechanism III pushes the chip suction box to translate to the chip suction position. The bottom of the chip suction box is provided with a chip inlet.

[0007] Preferably, both sides of the blade are provided with cutting edges, and the cutting edge on the bag opening side of the blade is a bevel edge.

[0008] Preferably, the lifting execution element of the power lifting mechanism is a lifting drive cylinder.

[0009] Preferably, the translation execution element of the power translation mechanism 1 is a lead screw motor driving a lead screw slider to translate, and the translation assembly 1 is a slider member.

[0010] Preferably, the translation execution element of the power translation mechanism 2 is an ejector cylinder, and the translation assembly 2 is a sliding bracket connected to the telescopic end of the ejector cylinder.
