Abstract

The invention relates to the field of plastic film production, and specifically discloses a blow molding machine head, which includes a machine head body and a mold core. A flow channel is formed between the machine head body and the mold core. A feeding trough connected with the flow channel is provided, and the vertical section of the feed chute is not parallel to the vertical section of the flow channel; a lifting unit that can drive the lifting platform to rise is provided above the material lifting platform. In this solution, the top of the thin-walled tube is fixed in the feeding trough of the lifting platform through the lifting platform, so that the lifting unit is used to drive the lifting unit and the thin-walled tube to rise together, which solves the problem caused by manual lifting in the prior art. to the problem of operational hazards.

Description

technical field [0001] The invention relates to the field of plastic film production, in particular to a blow molding machine head. Background technique [0002] With the advancement of human science and technology, plastic film has replaced most of the paper packaging as packaging. The demand for film is huge. The film can be formed by flat extrusion blowing method. , through the flow channel formed between the head body of the blow molding head and the mold core, the molten raw material is extruded to form a thin-walled tube, and then the thin-walled tube is blown by compressed air to form a film tube, and the film tube passes through the wind The ring is cooled and shaped, and the shaped film tube is then flattened by a herringbone plate to form a laminated film, and finally the film is pulled to the winding roller by the traction roller for winding to form a film product. [0003] But the prior art also has the following problems about the blow molding production of fil...
