Improved conveying pinch roller of ribbon inking machine

The utility model is an improved conveying pinch roller of a ribbon inking machine. The improved conveying pinch roller of the ribbon inking machine comprises a rack and a conveying pinch roller, wherein a conveying wheel shaft is fixed on the rack, the inner side of two ends of the conveying pinch roller are respectively fixed and connected with a bearing, the conveying pinch roller can be movably sleeved on the conveying wheel shaft, and a plurality of limiting ridges are formed on the conveying pinch roller at intervals. When a ribbon band base to be inked is fixed on the conveying wheel, the ribbon and the conveying wheel form a simultaneous rotation state, the ribbon band edge and the conveying pinch roller rotate simultaneously, the friction between the ribbon band edge and the inner side of the conveying pinch roller is almost reduced to zero, with the decreasing of the friction, and the vitreous crystals of the ribbon band are protected against breaking and damage naturally, thereby ensuring the quali
