Be connected through bolt between said moving knife and the moving knife push pedal, this bolt top is provided with look nut, and said look nut and moving knife push pedal are provided with spring.

Seal after said between die head and the heating plate and be provided with insulcrete.

The utility model is reliable; Easy to use, preceding seal die head and after seal die head cut-out action accomplish after, can realize immediately packaging film is added heat sealing; Can realize adjustment through regulating look nut to the packaging bag otch; Can regulate time of heat according to sealing effect, regulate easy to operately, and guarantee efficient that PE film involution cuts off and the aesthetics of sealing.
