Abstract

The embodiment of the invention provides a film blowing machine, and relates to the technical field of plastic manufacturing. The film blowing machine comprises an extruder, a mould head, a fixed core rod, a wind ring, a traction roller and an inverted-V-shaped rack, wherein a joint of the mould head and the fixed core rod is provided with a first air outlet; the first air outlet is arranged at the inner side of a discharge hole of the mould head; the fixed core rod is provided with a second air outlet; and the second air outlet is arranged on the rod body of the fixed core rod. According to the film blowing machine provided by the embodiment, the rod body of the fixed core rod is provided with the second air outlet, so that air-out is carried out through the second air outlet when the film blowing machine needs carrying out film blowing in a relatively large blow-up ratio, and therefore, uneven film thickness caused by too strong wind provided by the first air outlet at the joint of the mould head and the fixed core rod is avoided; and meanwhile, the first air outlet is mutually matched with the second air outlet, sot that the blow-up ratio of the film blowing machine can be regulated more flexibly.

Description

technical field [0001] The invention relates to the technical field of plastic manufacturing, in particular to a film blowing machine. Background technique [0002] When making plastic film, it is necessary to blow the melted raw material into a film through a film blowing machine. The blowing ratio of the generated film is controlled by the wind speed of the air outlet below the fixed core rod, but if the wind speed of the air outlet is large, the thickness of the film will be uneven. Contents of the invention [0003] The object of the present invention is to provide a film blowing machine, so that the problem of uneven thickness of the above-mentioned film can be improved. [0004] In order to achieve the above object, the technical solution adopted in the embodiment of the present invention is as follows: [0005] A film blowing machine includes an extruder, a die head, a fixed core rod, an air ring, a traction roller and a herringbone frame. [0006] The extruder i...
