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