Technical Field

[0001] This utility model relates to the field of PU wheel production technology, and in particular to a cutting mechanism for a PU wheel cutting machine. Background Technology

[0002] In existing technologies, after a PU wheel is formed, one side has a protruding edge, which needs to be cut off to obtain the finished PU wheel. Current methods involve manual edge cutting, which is inefficient, labor-intensive, results in inconsistent product quality, and poses safety hazards.

[0003] Authorization announcement number CN 205521538 U discloses a cutting mechanism for a fully automatic PU wheel cutting machine. The cutting mechanism has a supporting rotating seat with a protruding central shaft. The supporting rotating seat is adapted to place the wheel to be cut, and the central shaft is inserted into the central hole of the wheel to be cut. The supporting rotating seat drives the wheel to be cut to rotate. A positioning device has a protruding positioning post, which is arranged opposite to the central shaft and supports the corresponding side of the wheel to be cut. A cutting blade is set on a telescopic structure and is inserted into the wheel to be cut from the side.

[0004] The above solution still has shortcomings: it is inconvenient to trim the edges of PU wheels of different specifications, it is difficult to adjust, and it has poor adaptability. Utility Model Content
