Reversing fixed-distance feeding system for cylindrical tanks

The invention discloses a reversing fixed-distance feeding system for cylindrical tanks. The system comprises a feeding conveying belt and a monomer conveying belt joined together, wherein the monomer conveying belt is joined with a discharge conveying belt through a gap adjusting device; the feeding conveying belt and the monomer conveying belt are positioned on one vertical surface; the feeding conveying belt is driven through a feeding belt wheel; the monomer conveying belt is driven through a monomer belt wheel; a carrier surface at the top of the monomer conveying belt is higher than a carrier surface at the top of the feeding conveying belt; a lower bottom surface of the monomer conveying belt is lower than the carrier surface at the top of the feeding conveying belt; and the monomer conveying belt is a magnetic conveying belt. The system converts the lying transmission of the cylindrical tanks to the standing transmission by the feeding conveying belt and the monomer conveying belt with different heights; semicircular grooves peripherally and uniformly distributed on a turntable are used for accommodating the cylindrical tanks; and the turntable rotates with uniform speed, so that the cylindrical tanks ate uniformly thrown onto the discharge conveying belt.
