Vertical packaging machine three-side seal - filling - sealing
The vertical packaging machine is filled and sealed on three sides. The film of the reel is introduced into the elephant-like shaper after passing through a plurality of guide rolls, and the film is gradually curled into a butt cylinder at the lower end of the former, and then heated and pressed by a pair of longitudinal sealing rollers which are continuously reversely rotated. The longitudinal sealing roller is used for pulling the film in addition to the heat sealing action. After the packaged material is quantified by the metering device, the molding tube composed of the filling tube and the inner wall of the former is introduced into the plastic bag. The transverse sealer is driven by the non-equal speed mechanism, and the rotation axis of the horizontal seal is parallel with the rotation axis of the longitudinal sealer, and the continuous bag of the sealed mouth is cut off from the transverse seal edge when the rotary cutter and the fixed cutter are in contact with each other. Get a three-side sealed pocket. Since the plastic film has a smaller traction force than the lapel shaper when the elephant-like shaper is formed, the strength of the film is not high.
