[0025] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. A printing rubber roller with a detachable rubber roller sleeve and roller shaft proposed by the present invention. In this application, the printing roller assembly is used in conjunction with the mounting bracket assembly. The two ends of the printing roller assembly are respectively installed and connected to the mounting bracket assembly through the first connection assembly and the second connection assembly. When the printing roller assembly is damaged, first rotate the turntable in the reverse direction. The turntable drives the positive and negative thread screw rod to rotate in the reverse direction. Then, the two moving plates move in opposite directions. Then, the two clamping blocks move away from each other. Then, the two clamping blocks are respectively withdrawn from the two clamping grooves. The two clamping blocks give up the clamping and fixing work on the second connecting rod. Then, the user pulls the pulling column in the direction away from the printing roller assembly. The pulling column drives the sliding disk, the connecting shaft and the docking disk to move in the direction away from the first connecting rod, so that the docking disk moves to the maximum distance from the first connecting rod until the insertion rod is completely separated from the insertion hole. Then, the clamping between the docking disk and the first connecting rod is separated. At this time, move the roller shaft body in the direction away from the installation box, so that the second connecting rod is removed from the installation box. Then, the user pulls the printing roller assembly in the vertically upward direction, and the first connecting rod is withdrawn from the cavity in the middle of the transparent installation cavity block. At the same time, the printing roller assembly is separated from the first connection assembly and the second connection assembly. Then, the printing roller assembly is disassembled from the mounting bracket assembly. This setting realizes the effect of facilitating the installation and disassembly between the mounting bracket assembly and the printing roller assembly. The printing rubber roller does not need to be installed on the mounting bracket assembly by means of bolts and nuts, solving the problem that it is not conducive to replacement after the roller shaft body is worn, and facilitating the user to overhaul and maintain the printing roller assembly; 2. The roller shaft body and the rubber roller sleeve body are sleeved in a sliding manner, which makes it convenient for the user to disassemble the roller shaft body and the rubber roller sleeve body. In this way, it is convenient to maintain and replace the roller shaft body and the rubber roller sleeve body. When the rubber roller sleeve body is worn, aged or damaged, it can be easily disassembled from the roller shaft body for replacement or repair without replacing the entire rubber roller, reducing the maintenance cost and downtime; improving the printing quality of the device. Since the roller shaft body and the rubber roller sleeve body are detachable, different rubber roller sleeve bodies with different hardness, materials and surface treatments can be selected according to different printing tasks and ink characteristics to meet different printing requirements, thereby improving the printing quality and extending the service life; by regularly replacing the rubber roller sleeve body, the influence on the roller shaft body caused by the wear and aging of the rubber roller sleeve body can be avoided, the service life of the roller shaft body can be extended, and at the same time, the printing failures and downtime caused by problems with the rubber roller sleeve body can be reduced; 3. When the printing roller assembly needs to be used, first fix the installation bracket assembly used in conjunction with the printing roller assembly at the designated working location, turn on the working mode of the second motor, and the second motor drives the installation box to rotate. The engaging mechanism arranged inside the installation box is fixedly connected to the second connecting rod in an engaging manner. Then, the installation box will drive the second connecting rod and the printing roller assembly to rotate, and thus the printing roller assembly enters the rotational working state. When the thickness of the printing paper or printing plate is different and the height of the roller shaft body needs to be adjusted, turn on the first motor, and the first motor drives the threaded rod to rotate forward or backward. The threaded rod drives the lifting base block to move upward or downward. Then, the connecting block slides upward or downward along the limiting groove track. Thus, the lifting base block drives the connecting block and the printing roller assembly to perform lifting work, and thus the purpose of adjusting the height of the printing roller assembly is achieved. When the printing roller assembly is adjusted to the appropriate position, turn off the working mode of the first motor. This setting facilitates the user to adjust the installation height of the printing roller assembly, enables the printing roller assembly to be used in different printing environments, meets the needs of more customers, and improves the applicable range of the device.
