Description

The film-blowing die head of inflation film manufacturing machine

Technical field

The utility model relates to a kind of inflation film manufacturing machine, specifically refers to a kind of film-blowing die head of inflation film manufacturing machine.

Background technology

Inflation film manufacturing machine is special purpose machinery plastic pellet heating and melting being blown out again film.Its operation principle is, by extruder by melting after high-low pressure plastic heating, extruding, then blow out film bubble with compressed air when being extruded by die head, be then pressed into film by the pressure roller be arranged on above die head, and then carry out rolling, its structure is as shown in China Patent Publication No. CN2936694Y.

The die head of existing inflation film manufacturing machine is fairly simple, and its charging aperture only has one, once it breaks down, directly causes blown film operation to be interrupted.

In addition, the outside of the film-blowing die head of existing inflation film manufacturing machine can be provided with heating wire for carrying out heating and thermal insulation to mouthpiece die head, and this structure heat utilization efficiency is low, and energy consumption is large.

Summary of the invention

The purpose of this utility model is the shortcoming and defect existed to overcome prior art, and provides a kind of vibrational power flow reasonable, is incubated energy-efficient, and has the film-blowing die head of the inflation film manufacturing machine of multiple charging aperture.

For achieving the above object, the technical solution of the utility model includes main die body, the feed runner described main die body being provided with charging aperture, being arranged at annular die on main die body outer face and being communicated with in main die body between charging aperture and annular die, the center of described main die body is provided with the fresh air inlet of longitudinally through main die body, it is characterized in that: described charging aperture is provided with at least two, and be provided with feed runner between each charging aperture and annular die, described multiple feed runners with the central axis of main die body for axle is symmetrically set;

Described main die body overcoat is provided with infra-red radiation warmer, this infra-red radiation warmer includes cylindrical housing and the uniform multiple infrared heating pipes be arranged on cylindrical housing inner tube wall, described cylindrical housing includes the shell semicircular ring of two splits that are hinged, and two shell semicircular ring are provided with the snap close be fastened for two shell semicircular ring at the opposite side of its hinged place.

The quartz ampoule of further setting to be infrared heating pipe be in-built electrical heated filament.

By this setting, can realize multiple throat-fed, thus ensure the stability of blown film charging, in addition, adopt infra-red radiation warmer to be incubated main die body in infra-red radiation mode, heat losses is few, good energy-conserving effect.

Below in conjunction with specification drawings and specific embodiments, the utility model is described further.
