Roller mounting structure of aluminum-foil paper embossing machine

The utility model relates to the technical field of embossing machine rollers, in particular to an aluminum-foil paper embossing machine roller installation structure which comprises a roller, the roller comprises a roller shaft, locking mechanisms are arranged at the two ends of the roller shaft in a matched mode, a driving mechanism is arranged above the roller, and each locking mechanism comprises a ring body. The driving motor is started to drive the screw rod to rotate, the screw rod drives the two ring bodies to synchronously move towards each other or move away from each other, the positions of the two ring bodies are adjusted, the power motor is started to drive the two gears to rotate, the two gear rings and the adjacent threaded cylinders are driven to rotate through the two gears, and the two screwing rings move on the adjacent threaded cylinders. And during moving, the multiple adjacent supporting rods pull the multiple adjacent sliding frames to move in the adjacent guide grooves, so that the mul
