ABSTRACT:
A packing machine for spherical vegetables includes a machine body, a film-cutting part, a film-gripping part, a clamp device and a heat sealing mechanism. The film-cutting part is installed on the rear part of the machine body and can be moved upwardly and downwardly. The clamp device is situated behind the film-cutting part for clamping the packing film. Furthermore, the film-gripping part is installed opposite to the clamping device and can slide forwardly and backwardly upon two guide rails by means of a motor driven transmission chain. When starting the packing machine, the film-gripping part moves forwardly to the clamping device to grip the packing film and then returns to its original position. Meanwhile, the film-cutting part is lowered to cut off the packing film. Then a spherical vegetable is placed on the packing film from a loading holder which is automatically lowered to an appropriate position while the heat sealing mechanism clamps and seals an upper part of the packing film.
