Gap adjusting mechanism for conveying belt of box gluing machine

The utility model relates to the technical field of mechanical equipment, in particular to a gap adjusting mechanism for a conveying belt of a box sticking machine, which comprises a lower beam and an upper beam, a gap is reserved between the upper beam and the lower beam, the upper beam is arranged above the lower beam, and a plurality of rollers partially penetrating through the upper end face of the lower beam are arranged on the lower beam. The rocker arms are supported by a plurality of supporting rods and suspended on one surface of the upper beam, and the connecting rod assembly is provided with a plurality of soft rollers, is driven by a driving mechanism, is linked with the rocker arms to ascend and descend and is used for adjusting the gaps between the rollers and the conveying belts between the rollers and the soft rollers. Gaps can be adjusted in a parameterized mode, the stability of paperboard conveying and the adaptability to different paperboards are enhanced, and the risks of paper blocking a
