The design of the mounting plates 6 and the mounting holes 8 facilitates the installation of the device in the usage position.

[0028] The working principle of this utility model is as follows:

[0029] In use, the printing roller 5 is first placed above the support plate 401. Then, the electric push rod 403 provides thrust, causing the connecting plate 402 to move the support plate 401 and the printing roller 5 upwards, so that the printing roller 5 is fitted onto the surface of the card holder 201. Next, the first motor 101 provides power to drive the connecting rod 102 to rotate inside the rolling bearing 103. At this time, according to the rotation of the connecting rod 102 and the gear 105, the rack 306 can be moved. Then, with the rebound force of the spring 302, the push plate 303 drives the slide rod 304 to slide, and pushes the insert block 305 to be inserted into the printing roller 5, thereby completing the installation and replacement of the printing roller 5. The design of the second motor 203 and the rotating rod 204 makes it easy for the rotating rod 204 to rotate inside the pressure bearing 202, driving the card holder 201 to rotate. At this time, the printing roller 5 drives the insert block 305 to rotate inside the bearing seat.
