Specifically, the upper cover assembly 1 and the lower cover assembly 2 can be opened by the upper and lower switches 5, and printing adjustment and maintenance can be performed. The mounting mechanism is mainly used for mounting the label paper, and the label paper can be printed after being mounted. The label paper is easy to be mismatched with the mounting mechanism due to the size or the effect of external force, namely, the joint of the two sides of the label paper and the mounting mechanism is loose or has a gap, so that the label paper is skewed or even wrinkled during printing, and the printing quality is affected. The conveying assembly 4 can drive the carbon belt 26 to move, and the pressure on the carbon belt 26 is adaptively adjusted through the adjusting mechanism, so that the pressure on the carbon belt 26 is balanced everywhere, and the carbon belt 26 is not easy to wrinkle and skew. The print head 25 is disposed above the carbon ribbon 26 after bypassing the adjustment assembly, and after printing the carbon ribbon 26 by the print head 25, the carbon ribbon 26 leaves a corresponding mark on the label paper under printing by the print head 25 due to the contact of the carbon ribbon 26 with the label paper. The paper clamping assembly clamps two sides of the label paper, so that the position of the label paper is limited, and the label paper is prevented from being skewed.

The adjusting spring 24 is connected with the adjusting rod 27, and the adjusting spring 24 is elastically deformed to different degrees after receiving the pressure on the adjusting rod 27, so that the adjusting rod 27 is correspondingly moved, and the pressure of the carbon ribbon 26 is adjusted. Specifically, after the two ends of the adjusting rod 27 are connected with the adjusting springs 24, the adjusting rod 27 can adaptively adjust the pressure on the carbon ribbon 26, so that the pressure of the carbon ribbon 26 is balanced, the phenomenon that the carbon ribbon 26 is wrinkled or skewed due to uneven pressure is reduced, and the printing quality of the label paper is improved.
Alternatively, the conveying assembly 4 includes a driving roller and a driven roller, and the driving roller is used for driving the carbon ribbon 26 to move from the driven roller to the driving roller after rotating.

The carbon ribbon 26 and the drive spring 28 can rotate together with the drive wheel 23. The driven roller comprises a driven wheel 20, a driven shaft and a driven spring, wherein a carbon belt 26 is arranged on the driven shaft between the driven wheel 20 and the driven spring.
