Description

TECHNICAL FIELD

[0001] The utility model relates to a film blowing machine, concretely relates to an automatic winding mechanism of film blowing machine. BACKGROUND

[0002] The film blowing machine is a special equipment for realizing plastic film production. The winding mechanism is an important component of the film blowing machine, which is mainly used for winding and collecting the produced film material. In the traditional winding mechanism, a single placing part is arranged on the swing frame when changing the winding roll. The winding completed shaft is placed on the placing part of the swing frame. Then the swing frame is controlled to swing outward. The shaft on the swing frame is taken away. Then the shaft to be wound is placed on the swing frame and sent into the winding mechanism. Then the shaft to be wound is manually pushed to the waiting station. The defect of this structure is that after the swing frame sends the shaft to be wound, the shaft to be wound needs to be sent to the waiting station. At this time, the placing part on the swing frame can be emptied and used to receive the shaft that has been wound. The overall operation of the equipment is not smooth. In addition, since the position of the placing part on the swing frame is fixed, when the diameter of the wound film roll becomes larger, the swing frame may cause the film to directly contact and extrude the ground when swinging outward, which affects the normal collection of the film.
