FLANGING MECHANISM AND CAN-MAKING PRODUCTION LINE

WIPO Patent Application WO/2022/057137

A1

The present invention relates to a flanging mechanism, comprising: a flanging frame, an inner flanging mold and an outer flanging mold arranged on the flanging frame, and a power drive system for pushing the inner flanging mold and the outer flanging mold to move. The inner flanging mold and the outer flanging mold are driven by the power drive system to translate in opposing directions or in opposite directions. When the flanging mechanism flanges the wall of a can, the wall of the can is located between the inner flanging mold and the outer flanging mold, the outer flanging mold moves inward to abut the outer wall of the can, and the inner flanging mold moves outward to push the mouth of the can outward. A can-making production line comprises a rotary welding seam positioning mechanism, an expanding mechanism, a printing mechanism, a bottom sealing mechanism, a dust removal mechanism, a necking mechanism, a can sealing mechanism, and the flanging mechanism. The present invention ensures the stability of flanging pressure, ensures the quality of flanging, improves the production speed of cans, increases the quality stability of finally produced cans, and ensures good quality of the produced cans.
