Description

Technical Field

[0001] This utility model relates to the technical field of air shaft cutting machines, specifically a synchronous belt air shaft cutting machine. Background Technology

[0002] In the production process of transmission belts, the belt drum needs to be cut at equal intervals using a transmission belt cutting machine according to customer requirements to form a ring-shaped transmission belt with a consistent width. Currently, in common cutting processes, the transmission belt is usually tensioned by a spindle and a tensioning shaft. The belt drum is then rotated under the rotational drive of the spindle, and then the cutting assembly cuts the belt drum.

[0003] A current publication (CN221456094U) discloses a small-pitch transmission belt cutting machine, comprising: a frame; a clamping drive device; a clamping device; an air-expanding shaft, which includes a shaft core, a bushing sleeve fitted outside the shaft core, and an air bladder located between the bushing sleeve and the shaft core; wherein, both ends of the shaft core are respectively assembled with the clamping drive device and the clamping device; a belt sleeve is installed on the bushing; during the inflation and deflation of the air bladder, the bushing is driven to expand and contract radially along the shaft core; a cutting assembly is movably mounted on the frame and located below the air-expanding shaft; the belt sleeve is installed on the air-expanding shaft to achieve tensioning and loosening during the expansion and contraction of the bushing; the cutting assembly moves towards the air-expanding shaft and abuts against the belt sleeve to perform cutting. The use of an air-expanding shaft to tension transmission belts with small circumference to complete the small-pitch transmission belt cutting process effectively solves the technical problem that the double-roller tensioning method cannot be adapted to small-pitch transmission belts.

[0004] Existing technologies cannot adequately protect the cutting blade and cannot effectively compress it during cutting. Therefore, we propose a synchronous belt air shaft cutting machine. Utility Model Content
