ABSTRACT:
A packing machine includes a frame on a bottom of which a motor is mounted which has a rotary shaft laterally protruding therefrom. A sprocket train is securely mounted around the rotary shaft of the motor to rotate therewith. A chain train is mounted in the frame for co-operating with the sprocket train. A first sealing module is mounted on the side portion of the frame and is driven by the chain train for coupling the two opposite edges of the plastic film together. A second sealing module is mounted on the side portion of the frame below the first sealing module and is driven by the chain train for sealing the bottom end of the plastic film. A guiding device is mounted on the side portion of the frame for introducing the plastic film to smoothly move through the first sealing module and the second sealing module. A supply device is mounted on the top portion of the frame and includes fluid material contained therein for supplying the fluid material into the plastic film whose two opposite edges and bottom end are respectively sealed by the first and second sealing modules.
