Problems solved by technology

However, the equipment used for compound co-extrusion is usually composed of more than two screw extruders. The equipment structure is complex, the floor area is large and the manufacturing cost is high. Moreover, the molten materials from different extruders must reach Production requirements need to be redistributed and distributed, which will inevitably affect product quality, appearance and production efficiency

Abstract

The invention provides a compound co-extrusion machine with a single hollow screw rod. The compound co-extrusion machine comprises a motor, a transmission mechanism, a base, a radial-thrust bearing set, a barrel, the hollow screw rod, an electric heating ring, an extrusion machine head, a first hopper, a second hopper, a gear and a mandrel. According to the compound co-extrusion machine provided by the invention, the structure is simplified, the total quantity of devices is decreased, and the manufacturing cost, using cost and the maintenance cost are all reduced.

Description

technical field [0001] The invention relates to a hollow single-screw composite extruder, which can be used for composite co-extrusion of plastic products such as composite pipes, composite plates, composite sheets and various cables. Background technique [0002] Co-extrusion is an extrusion processing method in which two or more different materials are compounded and extruded, and after cooling and shaping, it becomes a multi-layer product. At present, common composite co-extrusion materials include composite pipes, composite sheets, composite sheets, and optical cables. However, the equipment used for compound co-extrusion is usually composed of more than two screw extruders. The equipment structure is complex, the floor area is large and the manufacturing cost is high. Moreover, the molten materials from different extruders must reach Production requirements need to be redistributed and distributed, which will inevitably affect product quality, appearance and production...
