The invention discloses a
plastic film heat-sealing device, which comprises a heat-sealing box. A film storing notch is formed in one side of the heat-sealing box, a film placing mechanism is arrangedon the surface of the film storing notch, a
hydraulic pump is mounted on the upper surface of the heat-sealing box, a film
cutting mechanism is arranged at the position, at the
hydraulic pump, insidethe heat-sealing box, a film conveying mechanism is arranged at the position, below the film
cutting mechanism, inside the heat-sealing box, the film conveying mechanism comprises a
metal transmission belt and two sets of transmission wheels, a plurality of sets of mounting openings are evenly formed in the upper surface and the lower surface of the
metal transmission belt, suction cups are mounted in the mounting openings, one ends of the suction cups are connected with hoses in a communicating mode, an
air pump is fixedly mounted inside the
metal transmission belt, and the hoses are connected with the air outlet end of the
air pump in a communicating mode. In the using process of the
plastic film heat-sealing device, a
plastic film coil is placed conveniently, and a film subjected to heat sealing can be moved to a film outlet to be discharged
through transmission of the metal transmission belt; and artificial manual operation is not needed in the heat sealing process, and the heat sealing efficiency of the plastic film is improved.
