AI Technical Summary

Technical Problem

In the existing technology, the screw disassembly of the twin-screw extruder for heavy-duty tire nano-rubber compound is time-consuming and labor-intensive, and the threads of the fixing bolts are easily damaged after long-term use, which affects the quality of rubber compound processing.

Method used

The design incorporates a sealing component, a moving component, a support component, and a snap-fit ​​component. By rotating the moving component, the support component is moved, the snap-fit ​​is released, and the sealing component is flipped over, making it easy to remove the screw for cleaning, preventing the sealing component from loosening, and improving the sealing performance.

Benefits of technology

It enables convenient disassembly and cleaning of the screw, reduces operation time and thread damage, and ensures the quality of rubber processing.

Abstract

The utility model discloses a kind of heavy-duty tire nanometer sizing material double-screw extruders, it is related to nanometer sizing material extrusion technical field.The utility model includes extruder: extruder is separately provided with sealing assembly, moving assembly, support assembly and clamping assembly;The utility model is moved by rotating moving assembly, make it drive internally slidingly arranged support assembly to move, since the side of clamping assembly and the side of sealing assembly are fixedly connected, and the bottom end of clamping assembly and the top end of support assembly are fixedly connected, and then when support assembly moves, it can drive the clamping assembly of fixed top to move, to make clamping assembly remove its clamping setting during moving, then pull sealing assembly, make it overturn, to make the screw inside extruder leak, then the screw is taken out and cleaned, it is more time-saving and labor-saving, and sealing assembly can avoid loosening during use, to ensure the processing quality of extruder to sizing material.
