PE pipe three-section metering high-speed single-screw extruder

Abstract

The invention provides a PE pipe three-section metering high-speed single-screw extruder, and belongs to the technical field of machinery. The PE pipe three-section metering high-speed single-screw extruder solves the technical problems that an existing screw extruder is troublesome in feeding and the like. The PE pipe three-section metering high-speed single-screw extruder comprises a base, and is characterized in that a working barrel and a blending device are arranged on the base, a machining barrel is arranged on the working barrel, a screw is rotationally arranged in the machining barrel,a first power motor is further arranged on the base, the screw is connected with an output shaft of the first power motor through a reduction gearbox, a first feeding port is formed in one end of themachining barrel, the other end of the machining barrel is connected with a discharging nozzle, a feeding device is further arranged on the machining barrel, the feeding device communicates with thefirst feeding port through a drying box, the feeding device communicates with the blending device, a heating device is further arranged on the working barrel, the heating device is connected with a moving structure, and a heat circulation mechanism is further arranged on the base. The PE pipe three-section metering high-speed single-screw extruder has the advantage of high working efficiency.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to an extruder, in particular to a three-section metering high-speed single-screw extruder of a PE pipe. Background technique [0002] The screw extruder relies on the pressure and shear force generated by the rotation of the screw, so that the material can be fully plasticized and uniformly mixed, and formed through the die. A single screw is generally divided into three sections in terms of effective length, and the effective length of the three sections is determined according to the diameter of the screw, the pitch and the depth of the screw, which are generally divided into one third each. The last thread of the material port begins to be called the conveying section: the material here is required not to be plasticized, but it must be preheated and pressed to be firm. In the past, the old extrusion theory believed that the material here is a loose body, and later by proving the...
