Description

Technical Field

[0001] The utility model relates to the technical field of rebar winding machines, in particular to a rebar winding machine. Background Art

[0002] A rebar cage winding machine is a common device used to prepare rebar cages. It primarily consists of a traveling and pay-off mechanism and a rolling mechanism. Prior art Chinese invention patent application CN116393629A proposes a rebar cage winding machine for prefabricated components. This machine supports the rebar cage frame with two rows of rollers during winding. A cage connecting frame at the output end of the drive assembly then connects to the main rebar at the cage end. During the winding process, the drive assembly rotates the rebar cage, while the two rows of rollers provide only support. This effectively avoids the problem of relative slippage of the rebar cage frame during winding, which can lead to inconsistent winding spacing, as is common with existing rebar winding machines that rely on the rotation of the rollers. This effectively ensures the dimensional accuracy of the rebar cage winding and improves product quality.

[0003] However, the cage frame rolling mechanism of the above-mentioned rebar winding machine is placed at the end transmission contact of the steel cage. The transmission contact area is small. Due to the large weight of the steel cage, the longitudinal bones of the steel cage will bend, which will cause the two ends of the steel cage to be easily twisted, which is not conducive to the welding quality of the steel cage.
