Main gearbox assembly of single screw extruder and its application

Abstract

The invention relates to a main gearbox assembly of a single-screw extruder and application of the main gearbox assembly. The main gearbox assembly comprises a main gearbox and a thrust screw, wherein the main gearbox is a hollow output shaft, an internal spline is arranged at the tail end of the main gearbox, and two locating holes are formed in the tail end at the same time; a thrust spiral is arranged at the front part of the thrust screw, a locating neck is arranged at the rear part, an external spline and bulged shaft necks are arranged on the locating neck, the diameters of the bulged shaft necks are larger than that of the thrust spiral, and smaller than that of the external spline at the tail end; the hollow output shaft is equipped with an adjusting pad and a rear pressing cover on the surface of the tail end, and equipped with an external gear sleeve at the front end, the external gear sleeve is provided with an internal hole, and the diameter of the internal hole in the external gear sleeve is larger than that of the thrust spiral; after the thrust spiral at the front end of the thrust screw penetrates the inner hole in the external gear sleeve, the bulged shaft necks are placed in the locating holes of the hollow output shaft, and the external spline is engaged with the internal spline; a rotation joint penetrates the rear pressing cover and the adjusting pad, and is connected with the thrust screw and communicated with a circulating water channel in the thrust screw. During use, a rubber extruding unit is equipped with at least one material conveyor containing the gearbox assembly of the single-screw extruder.

Description

technical field [0001] The invention relates to a main gear box assembly matched with extruding machine equipment in the rubber industry, in particular to a main gear box assembly of a single-screw extruder. Background technique [0002] With the continuous development of our country's economy, the automobile industry has shown its importance in economic development more and more. Its rapid development has also led to the vigorous development of rubber products and tire industries. With the continuous development of the rubber tire industry, higher requirements have been put forward for the production equipment of related industries. As a necessary equipment in the rubber processing industry, the demand for single-screw extruders has increased. As a key production equipment, the gearbox puts forward higher requirements for the design and manufacture of the gearbox due to the very special operating conditions of the single-screw extruder. Large-scale, high-speed, multi-com...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to: aim at the current single-screw extruder gearbox screw can only be disassembled from the front, the workload is relatively large, and the traditional way of water supply from the inner hole of the output shaft will endanger the positioning accuracy of the thrust screw, and even cause the thrust screw to be damaged in severe cases. To solve a series of problems such as bore sweeping accidents, provide a new main gearbox for single-screw extruder and its application
