Abstract

A vacuuming and packaging method for a turret-type multi-station adaptive vacuum tray. The method is implemented on the basis of a turret-type multi-station adaptive vacuum tray apparatus. The apparatus comprises a turret base (1). One rotating turret (2) driven by a motor (102) is laid on the turret base (1). A plurality of material bag vacuuming stations are provided around and connected to the rotating turret (2). The material bag vacuuming stations comprise bag support plates (3) and material bag vacuuming and shaping covers (9) that may move up and down. The bag support plates (3) are provided with a material bag grippers (4), bag mouth heat seals (5), bag pushing mechanisms (6) and material bag vacuuming platform plates (7). The material bag vacuuming and shaping covers (9) are provided directly above the material bag vacuuming platform plates (7) when the bag support plates (3) are in a horizontal state. Each bag support plate (3) is connected to a push arm mechanism. The push arm mechanisms push the bag support plates (3) to be in an erect state and a horizontal state. A lifting mechanism (11) is further provided on each bag support plate (3). The lifting mechanisms (11) are connected to the material bag vacuuming platform plates (7), and the lifting mechanisms (11) raise or lower the material bag vacuuming platform plates (7). The vacuuming and packaging method comprises preparation work before packaging, and vacuuming and packaging steps performed at each station.

Abstract

The present invention discloses a biomimetic bag opening device for an automatic filling line, comprising brackets left and right symmetrically arranged on the filling line for filling bags, the symmetrically arranged brackets moving in a horizontal relative motion respectively driven by a pull rod, a push bag plate facing the filling bag provided at a front end of the bracket, a row of gripper holes provided on the push bag plate in the upper and lower of the horizontal level respectively, two rows of grippers provided on the brackets behind the push bag plate and corresponding to the two rows of gripper holes, a gripper drive device driving two rows of grippers open or closed, and grasping fingertips of the grippers projecting or retracting from two rows of the upper and lower of the gripper holes. The present invention solves the problem that woven bags are automatically opened in a full-automatic weighing and packaging device, which can be used for the production of the non-lamination woven bag, semi-lamination woven bag and full-lamination woven bag. The grippers of present invention imitate the human fingers to grip woven bags and separate the bag mouth, the bag mouth can also be closed to prepare for next process after bagging completed, and structure installation and adjustment are convenient.
