Abstract
Claims
1. An opening device for an automatic dispensing machine in a hospital pharmacy, characterized in that: The device includes a frame, a vertical pressure rod, a rotating rod, a cutting head, and a medicine bottle holder. The vertical pressure rod is vertically slidably and rotatably fitted onto the frame. The rotating rod is slidably and rotatably fitted onto the central hole of the vertical pressure rod. The cutting head is an inverted cone shape with three or more inverted conical blades evenly distributed on its conical side. The outer ends of the inverted conical blades are provided with vertically moving cutting edges and circumferentially moving cutting edges. The lower end of the rotating rod extends out of the lower end hole of the vertical pressure rod and is coaxially connected to the top side of the cutting head. The upper end of the rotating rod extends out of the upper end hole of the vertical pressure rod and is provided with a first operating handle. The lower end of the vertical pressure rod contacts the top side of the cutting head, and its upper end is provided with a second operating handle. A medicine bottle holder is provided on the frame below the cutting head, and the central axis of the medicine bottle holder is coaxial with the central axis of the cutting head.
2. The opening device of the automatic dispensing machine for hospital pharmacy according to claim 1, characterized in that: The outer end of the inverted conical blade is provided with a vertically moving cutting edge and a circumferentially moving cutting edge. A protruding ridge is provided on the side of the outer end facing the rotation direction. The inner front end line of the protruding ridge to the outer end line of the outer end facing away from the rotation direction forms an inclined surface. The outer end line of the outer end facing away from the rotation direction and the inclined surface constitute the vertically moving cutting edge, and the inner front end line of the protruding ridge and the inclined surface constitute the circumferentially moving cutting edge. The lower ends of the vertically moving cutting edges on all the inverted conical blades of the cutting head are connected together to form the cone tip of the cutting head.
3. The opening device of the automatic dispensing machine for hospital pharmacy according to claim 2, characterized in that: The distance between the circumferential cutting blade and the outer end of the inverted conical blade facing away from the rotation direction is set to 1-2 mm, and the distance between the vertical cutting blade (7) and the inner end face of the protruding ridge is set to 1-2 mm.
4. The opening device of the automatic dispensing machine for hospital pharmacy according to claim 1, 2 or 3, characterized in that: The vertical pressure rod and the rotating rod are respectively provided with mutually cooperating locking blocks to limit the rotation angle of the rotating rod relative to the vertical pressure rod, so that each cut sealing film is not completely cut off, but leaves a small connecting part.
5. The opening device of the automatic dispensing machine for hospital pharmacy according to claim 4, characterized in that: The upper outer wall of the vertical pressure rod is provided with a radially protruding start position locking block and an end position locking block, and the upper outer wall of the rotating rod is provided with a radially protruding and downwardly extending limiting locking block. The limiting locking block is movably engaged between the start position locking block and the end position locking block to limit the rotation angle of the rotating rod relative to the vertical pressure rod.
6. The opening device of the automatic dispensing machine for hospital pharmacy according to claim 4, characterized in that: The tapered side of the cutting head is evenly distributed with four inverted conical blades, and the rotation angle of the rotating rod relative to the vertical pressure rod is set to 80 to 88 degrees.
7. The opening device of the automatic dispensing machine for hospital pharmacy according to claim 1, 2 or 3, characterized in that: The frame is equipped with a hanger for the first or second operating handle to ensure that the cutting head is stably positioned at a set height above the medicine bottle before and after the opening operation.
8. The opening device of the automatic dispensing machine for hospital pharmacy according to claim 1, 2 or 3, characterized in that: The medicine bottle holder has a recessed cavity at the center of its top side to accommodate the lower part of the medicine bottle. Several laterally protruding ball-head posts are evenly distributed on the cavity wall of the recessed cavity. The ball-head posts slide laterally on the sliding holes of the medicine bottle holder. A pressure spring is installed in the sliding hole. One end of the pressure spring is connected to the rear side of the ball-head post, and the other end is connected to the bottom surface of the sliding hole. The elastically expandable ball-head posts clamp the lower part of the medicine bottle in the recessed cavity.
9. The opening device of the automatic dispensing machine for hospital pharmacy according to claim 1, 2 or 3, characterized in that: The medicine bottle holder is configured as a detachable structure. The detachable structure has a recessed cavity on the frame base plate below the cutting head, directly opposite the central axis of the cutting head. The medicine bottle holder is an independent component and is equipped with multiple recessed cavities of different diameters. Each medicine bottle holder has a protruding part on its bottom surface that cooperates with the recessed cavity. When the medicine bottle holder is engaged with the recessed cavity on the frame base plate by its protruding part, the central axis of the recessed cavity on the medicine bottle holder is coaxial with the central axis of the cutting head.
