[0011] 1. When the printing roller needs to be disassembled and replaced, the sleeve wrench can be set on the twisting block, and then the printing roller is held to keep it stationary, and the screw rod is rotated so that the screw rod drives the movable rod to move in the direction close to the twisting block under the action of the thread, and at this time, the slider is stuck in the inside of the slide groove to prevent the movable rod and the driven shaft from rotating relative to each other, resulting in the situation that the movable rod cannot be retracted; in this way, the movable rod can be used to drive the block on the driven shaft side to disengage from the slot and away from the block on the driving shaft, and at this time, there is enough space on the driven shaft side for the printing roller to move, so that the printing roller can be easily disassembled, and then the printing roller can be lifted from the upper end to be disassembled; in this way, the disassembly process of the printing roller is convenient and quick.

[0012] 2. When the printing roller needs to be installed, the utility model first sets the printing roller on the block on the outer surface of the driving shaft through the slot, and then reverses the screw rod so that the screw rod drives the movable rod and the block to be inserted into the slot on the other side of the printing roller under the action of the thread, so that the driven shaft is also connected to the printing roller, and the fixing of the printing roller is completed. The whole fixing process is also convenient and fast. At this time, the power connection can be quickly completed after the installation is completed, so as to drive the printing roller to rotate conveniently.

[0013] 3. When the utility model is used, after the printing roller is disassembled, the printing roller is equivalent to being lifted up by the ink transfer roller, and will not fall suddenly under the limit of the squeezing roller. It is equivalent to the ink transfer roller and the squeezing roller supporting the printing roller during disassembly, and the printing roller will not fall unexpectedly after the card block is separated from the card slot, thereby improving the safety of the device when in use.
