Abstract: Disclosed is an intermittent moving mechanism, which belongs to the technical field of conveying devices and includes a guide rail; a sliding block moving along the guide rail, two stop blocks arranged at intervals, wherein a distance between the two stop blocks is greater than a length of the sliding block along an extension direction of the guide rail, and the sliding block is positioned between the two stop blocks; and a reciprocating movement structure, configured to push the two stop blocks to move synchronously and reciprocally along an extension direction of the guide rail. The reciprocating moving structure in the intermittent mechanism continuously operates, which avoids repeated starting and stopping and speed changes of the prime mover, and is beneficial to reducing the operation energy consumption and reducing the noise pollution to the environment.
