The invention discloses a rubber roller assembly. The rubber roller assembly comprises a rubber roller. The rubber roller is provided with a roller body and a rubber blanket. The roller body comprises a main roller body and a shaft fixed to the main roller body. The shaft is provided with a clamping and fixing device used for clamping the rubber blanket. Meanwhile, the clamping and fixing device and the shaft are fixedly connected, one end of the shaft is sleeved with a worm gear in a connected manner, a worm is fixed to the end, close to the worm gear, of the main roller body, and the worm gear and the worm are engaged. The clamping and fixing device is arranged on the shaft and used for clamping the rubber blanket, meanwhile, the clamping and fixing device and the shaft are fixedly connected, and therefore the problem that the rubber blanket is not convenient to dismount or mount can be solved. One end of the shaft is sleeved with the worm gear in the connected manner, the worm is fixed to the end, close to the worm gear, of the main roller body, the worm gear and the worm are engaged, and therefore the tightness degree of the rubber blanket can be adjusted according to the actual operation environment. Operation is very simple, reliability is high, and the work efficiency is improved.
