The guide connecting hole 431 plays a role of vertical direction guidance and provides a height direction movement allowance for the correction adjusting plate 43.

[0033] The first guide shaft 32 and the second guide shaft 42 are respectively supported on the guide support seat 5, the guide support seat 5 is provided with at least two guide support seats 5, and at least two guide support seats 5 are respectively located at the end positions of the first guide shaft 32 and the second guide shaft 42.

After the adjustment is completed, each locking bolt 47 is locked and fixed.

[0039] If the starting position of the labels 6 on the containers is higher than the length position of the container circumference L, the deviation rectifying adjusting hand wheel 461 is reversely rotated for adjustment.

[0040] The label rectification mechanism of the labeling platform has simple structure and is convenient to adjust.

[0041] In the embodiment 2, the guide support base 5 is supported on the labeling platform frame 10 by a lifting driving mechanism.

The lifting power mechanism can comprise a driving shaft, a speed reducer and a screw rod assembly. The lifting adjusting hand wheel 52 is installed on the driving shaft. The driving shaft drives the nut in the screw rod assembly to rotate through the speed reducer, thereby driving the screw rod in the screw rod assembly to move upward or downward, so as to realize the lifting movement of the lifting rod 51. In the embodiment, only the lifting power mechanism is taken as an example. The structure of the lifting power mechanism is not limited as long as it can drive the guide support base 5 to move vertically upward or downward.

[0042] The guide support base 5 is supported on the labeling platform frame 10 by the lifting driving mechanism, which facilitates the adjustment of the height of the labeling platform frame 10, thereby better adapting to the height of the filling platform of the filling machine 7.

[0043] Therefore, the labeling platform has the advantages of simple and ingenious structure. The height of the labeling platform 1 at one end is adjusted to change the height of the labeling position, thereby realizing the rectification of the label. The rectification and adjustment are very convenient, and the label can be quickly rectified.
