The working principle of the two-component experimental machine

The two-component experimental machine operates according to the principle of accurate mixing, conveying and testing of two-component materials. Taking the two-component spinning experimental machine as an example, its working flow is as follows:

Raw material delivery: The screw feeder continuously and evenly feeds two different raw materials into the parallel twin-screw extruder to ensure that the raw materials enter the subsequent treatment process stably and quantitatively.

Melting and temperature control: In the parallel twin-screw extruder, the raw material goes through multiple stages of heating and temperature control to achieve melting and exhaust. The temperature of each section can be accurately regulated to meet the processing needs of different materials, so that the raw material can achieve the ideal melting state.

Metering and extrusion: Driven by a cycloidal pinwheel reducer, the melt gear metering pump precisely controls and ensures the quantitative and stable extrusion of polymer melt to the spinning assembly. The precise metering function of the metering pump is crucial to the accurate control of the properties of two-component materials.

Molding and testing: In the spinning assembly, the melt is filtered, distributed, and pressed into a porous spinneret. Under the high-speed drawing action of the winding roller, the fiber strands are formed by cold solidification in the air cooling zone, and finally by the winding machine. At the same time, the equipment monitors and tests the strength, fineness, tensile properties and other performance indicators of the fiber bundles in real time.
