Abstract
The invention relates to a fold-preventing spreading device for a plastic film. The fold-preventing spreading device comprises a supporting frame and a spreading device. The spreading device is installed on the left side face of the right end of the supporting frame. The spreading device comprises a spreading air cylinder, a pressing support, a supporting plate, a guide pillar, a spreading connecting plate, a wheel connecting pillar, a spreading wheel and a spreading spring. The spreading device can be used for evenly spreading the plastic film so that the plastic film can be subjected to thehot sealing action flatly. The outer end of the supporting plate is connected with a pressing frame in a sliding manner. The right end of the pressing frame is installed on the right side face of thesupporting plate through a pressing spring. The pressing frame can press the plastic film needing to be subjected to hot sealing in a stressed manner, and the hot sealing effect of the plastic film isfurther improved. By means of the fold-preventing spreading device for the plastic film, the problems that when an existing plastic film is subjected to hot sealing, spreading cannot be conducted atthe upper portion and the lower portion of the plastic film at the same time, folds can occur on the plastic film, and the hot sealing area of the plastic film cannot be limited in a stressed manner can be solved.
