Problems solved by technology

[0006] However, the structure of the traditional casting co-extrusion film die head distributor is relatively compact and simple, but the distributor divides the molten raw materials extruded by three extruders into five layers through the cylindrical runner distributor. Among them, the 2nd, 3rd, 4th, 5th layers must be the same raw material, limited by the mechanical structure and space, the cylindrical flow channel distributor should be made of more than seven layers, and the film thickness adjustment is realized by adjusting the swing blade, processing and manufacturing High precision, very difficult

Abstract

The invention relates to a multifunctional full-automatic distributor device for a casting co-extrusion molding film. The device is characterized by comprising a connecting seat and a distributor upper part and / or a distributor lower part, wherein the distributor upper part and / or the distributor lower part are fixedly connected through the connecting seat; a runner gap regulating mechanism is respectively arranged below each feed inlet; and each runner gap regulating mechanism comprises a servo motor, a planet-gear speed reducer and a gap regulating block. The device has the advantages of flexible structure, high universalization degree, wide application range, independent runners, high regulating precision and reliable action; the servo motors are used for driving the gap regulating blocks, and the sizes of the runner gaps can be fully automatically and precisely controlled through setting the revolution number of the servo motors as required, thereby the thickness of the film is precisely controlled.

Description
