Extruder feeding device and extruder

Abstract

The invention discloses an extruder feeding device and an extruder. The extruder feeding device comprises a first feeding barrel and a first transfer device, wherein the first transfer device transversely penetrates through the inner cavity of the first feeding barrel; the other end of the first transfer device is connected with a first motor, and is driven by the first motor to rotate; at least two hoppers are mounted above a charge hole; the upper parts of the inner cavities of the hoppers are equipped with stirring devices; and the lower parts of the inner cavities of the hoppers are equipped with pressing devices. According to the extruder feeding device disclosed by the invention, the stirring devices are arranged on the upper parts of the inner cavities of the hoppers for carrying materials on the upper parts of the inner cavities of the hoppers to the lower parts of the inner cavities of the hoppers, the lower parts of the inner cavities of the hoppers are equipped with the pressing devices for pushing the lower materials of the inner cavities of the hoppers into the charge hole of the first feeding barrel, and the lower materials are conveyed into an extruder barrel body bythe first transfer device, so that light slices such as PET doped materials are effectively prevented from a bridging phenomenon above the hoppers.

Description

technical field [0001] The invention relates to the technical field of engineering management, in particular to an extruder feeding device and an extruder. Background technique [0002] As a packaging material, PET sheet is widely used in various industries, especially electronic packaging. PET can be directly used for packaging, such as packaging blister trays, blister cups, etc. However, most PET packaging exists in the form of composite materials, such as packaging films for electronic products or PET release films, etc., which are coated with a layer of adhesive on the PET sheet, and then adhered to the PP or PE film. When used, PP or PE is a covering film, which will be torn off before use. In addition, these packaging materials almost exist in the form of a roll, the middle part is used, and the two sides and the isolation part are incidentals, which become industrial waste or garbage. Usually these waste materials can be recycled, but these PET dopant materials are...

AI Technical Summary

Problems solved by technology

This kind of material is very easy to "bridge" when it is fed into the lower hopper of the extruder, causing the material to accumulate at the lower material opening and fail to enter the extruder, causing the extruder to break the material, and the equipment cannot work normally, thus seriously reducing the extrusion machine productivity
