AI Technical Summary
Traditional LNG ship insulation box foam board sanding equipment suffers from uneven sanding and insufficient precision due to center of gravity shift.
It adopts a split lifting design, with the first lifting frame carrying the sanding belt assembly and the second lifting frame carrying the sanding drive assembly. The synchronous control unit ensures that the two move synchronously. Combined with the V-shaped guide rail and V-shaped rollers and the brush cleaning, it avoids dust accumulation.
This achieves uniform sanding of the foam board surface and thickness tolerance control within ±10 microns, reducing equipment failure rate and service life.
