The inner side of the adjusting member 31 is rotatably sleeved with the end of the driven shaft 3. When the conveying chain 5 is tensioned and adjusted, the nut 34 is screwed outward, and the adjusting member 31 is slid inward on the adjusting port 11 by operating the screw 33 to adjust the distance between the driving shaft 2 and the driven shaft 3. When the chain 5 is relaxed and the transmission gear 4 is adjusted, the adjusting member 31 is pulled outward to re-tighten the conveying chain 5 for conveying objects.

[0043] The adjustment plate 6 is connected to the bracket side plate 1 through a telescopic drive mechanism 62, and the telescopic drive mechanism 62 is a telescopic cylinder, a hydraulic cylinder or a telescopic motor. The telescopic drive mechanism 62 can be used to synchronously push and adjust the transmission gear 4 on the same chain when the spacing of each conveying chain 5 is adjusted. The operation is simple and the adaptability is strong to the support positioning requirements at different locations along the length direction of different packaging boxes.
