AI Technical Summary
When processing rectangular guardrails, existing polishing machines can only form line contact between the grinding structure and the guardrail surface, resulting in low polishing efficiency and striped polishing defects on the surface.
By employing a coordinated adjustment mechanism and a pushing mechanism, the polishing modes of rectangular guardrails and post guardrails can be quickly switched. The tension of the polishing belt can be adjusted by a tension roller to ensure constant contact pressure under different working modes.
It enables a single machine to efficiently and adaptably polish guardrails with different cross-sectional shapes, improving the consistency of surface treatment quality and avoiding uneven polishing.
