Description

Technical Field

[0001] The utility model relates to the technical field of film collecting devices, in particular to a film collecting device of a film blowing machine. Background Art

[0002] The film blowing machine adds dry polyethylene particles into the lower hopper, and the particles enter the screw from the hopper by their own weight. When the particles come into contact with the bevel of the thread, the rotating bevel surface generates a thrust perpendicular to the bevel surface on the plastic, pushing the plastic particles forward. During the pushing process, due to the friction between the plastic and the screw, the plastic and the barrel, and the collision and friction between the particles, and also due to the external heating of the barrel, the molten plastic is filtered through the machine head to remove impurities, and comes out from the die head. It is cooled and inflated by the air ring, and the finished film is rolled into a tube by the material collection and winding device.

[0003] Referring to a Chinese patent for a receiving device of a film blowing machine (publication number: CN213770670U, publication date: 2021-07-23), the receiving device of the film blowing machine adopts a receiving frame body, and a guide roller is arranged at the film entrance. The two ends of the guide roller are symmetrically arranged at the top of the receiving frame. A film cooling device is arranged in sequence between the receiving frame bodies, and a pressing roller, an adjustment roller, and a winding roller are arranged in sequence along the film direction at the lower front position of the guide roller. The two ends of the winding roller are located on the receiving frame. There are grooves, and there are two groups of winding limit plates. The two groups of winding limit plates are respectively arranged at the two ends of the winding roller. Each group of winding limit plates is two pieces, and each group of winding limit plates is located on both sides of the groove. A counter is connected to the top of one side of the adjustment roller, and the counter is located on the outside of the receiving frame. The film is cooled before winding, and the winding amount of each roll of film is automatically counted, and the winding roller will not have a large offset. The problems of film adhesion, unstable film winding amount and poor film winding quality are solved.

[0004] However, the film-winding device of the existing film blowing machine still has the following problems. When winding the film, the existing film-winding device generally prevents the film from being loosened and causing poor winding effect by cooperating with the winding roller and the tensioning roller. However, the existing tensioning roller is generally fixedly installed on the surface of the support plate and is difficult to move, making it difficult to adjust the tensioning height according to the operator's needs during the winding operation.
