Embodiment Construction

[0035] The main principle of the rubber extrusion performance testing experimental machine of the present invention is;

[0036] ① Under the condition that a specific experimental testing condition remains unchanged, test and compare other required data parameters to obtain accurate and practical data results. The present invention is to use a set of power transmission device (motor, reduction box), equipped with screws with different thread structures, combined with advanced detection and control technology, to carry out extrusion performance test experiments on rubber compounds with various formulas.

[0037] ②Through the multivariate and multivariate comparison test experiments on the extrusion properties of various rubber compounds, it is possible to understand and grasp the extrusion properties of the compounds qualitatively and quantitatively, and to make accurate data collection. It is conducive to quick and simple application to the industrial production of enterprises...

Abstract

The invention provides an experimental machine for testing extrusion properties of rubber. The experimental machine for testing extrusion properties of rubber comprises a machine head, a machine body, a transmission mechanism, screws, a temperature control device and a control system. The control system comprises temperature thermocouples arranged on the machine body. The experimental machine for testing extrusion properties of rubber is characterized in that the screws have at least two helical structures; the tails of the screws are removably connected to a main transmission shaft of the transmission mechanism; and the control system also comprises an infrared temperature and speed detection device arranged on a rubber outlet of the machine head, and a torque sensing device arranged on an output shaft of a motor. The experimental machine for testing extrusion properties of rubber can realize comprehensive testing of extrusion performances of rubber prepared according to different formulas, provides reasonable and accurate technical conditions for actual production, improves the quality of rubber materials and rubber products, reduces energy consumption, and provides the basis for designing of various rubber extruders. The temperature control device has a simple structure, is convenient for control, and reduces a loss and a cost.

Description

technical field [0001] The invention belongs to experimental equipment in the rubber industry, and is mainly aimed at the performance test of the extrusion molding process of rubber materials, specifically a rubber extrusion performance test experiment machine. Background technique [0002] At present, rubber extruders are used as extrusion molding equipment in the production of rubber products. According to the feeding form, rubber extruders are classified into two types: hot feeding and cold feeding; according to the screw structure of the extruded rubber, they mainly include: ordinary thread screw, convergent thread screw, primary and secondary thread screw , screw pin type screw, barrel pin type screw and other series of specifications. Although there are many types and specifications of rubber extrusion molding equipment, there have been no reports about such equipment for comprehensive testing of rubber extrusion performance. [0003] In practical application, no mat...
