Film blowing device for plastic film production and processing

Abstract

The invention discloses a film blowing device for plastic film production and processing, and relates to the technical field of plastic film production and processing. The film blowing device for plastic film production and processing comprises a bottom plate; a first shell is arranged above a discharging hose; a supporting column and a vertical frame are welded and mounted at the top of the bottom plate; an auxiliary mechanism is arranged on the bottom plate; and a discharging mechanism is arranged on the first shell. According to the film blowing device, a cavity between the first shell anda second shell is filled with hot heat-conduction oil, so that the temperature is always the optimal temperature, the quality of an extruded film is guaranteed, and the production efficiency is improved; plastic raw materials in the second shell are molten, so that subsequent cleaning caused by the condition of adhesion of plastic raw materials due to temperature reduction during crushing and conveying is avoided; a first motor, a gear, transmission columns and spiral blades are arranged, and through arrangement of the two sets of transmission columns and spiral blades, the plastic raw materials are sheared more sufficiently during conveying, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of plastic film production and processing, in particular to a film blowing device for plastic film production and processing. Background technique [0002] The film blowing machine is a kind of equipment that heats and melts plastic particles and then blows them into films. Usually, the film blown out by the die head and the wind ring is a cylindrical film, and then passes through the herringbone-shaped film guide frame to obtain a finished sheet film with a two-layer structure. . [0003] At present, some blown film devices for plastic film production and processing only transmit the melted plastic raw material through the spiral blade, which is slightly inefficient, and it is easy to cause the plastic to solidify and adhere to it due to insufficient heating or slow transmission. Cause subsequent cleaning inconvenience and waste of plastic raw materials. Contents of the invention [0004] The object of ...
