[0049] The working principle of the present invention is as follows:

[0050] When the labeling machine for bottled bird's nest of the present invention is used, in the process of aligning the hexagonal bottle, according to the size of the hexagonal bottle, by changing the installation position of the two adjustment rings 75, the initial installation angle of the straightening plate 71 can be adjusted, and then the spacing between the limiting plate 2 and the straightening component 7 is adjusted by the transverse movement mechanism 50, so as to realize the adjustment of the width of the straightening channel. When the misplaced hexagonal bottle passes through the straightening plates 71 of each straightening component 7, the hexagonal bottle can be straightened under the gradual elastic shifting of each straightening plate 71; and according to the size of the hexagonal bottle, the distance between the straight segments 800 of the two alignment plates 80 can be adjusted to be slightly larger than the distance between the parallel surfaces of the hexagonal bottle. When the hexagonal bottle, which has been straightened by the limiting plate 2 and the straightening component 7, enters between the straight segments 800 of the two alignment plates 80 under the guidance of the arc segment 801, the hexagonal bottle can be further aligned, which can effectively improve the alignment accuracy of the hexagonal bottle, and facilitates the next step of accurately pasting the label 60 on the hexagonal bottle.

[0051] During the label 60 pasting process, firstly, according to the diameter of the hexagonal bottle, the distance between the limit plate 2 and the roller pressing mechanism 3 is roughly adjusted by the transverse mechanism 50, and then the distance between the limit plate 2 and the roller pressing belt 30 is finely adjusted by the support nut 3211; then, when the hexagonal bottle reaches the separation block 42 driven by the conveyor belt 1, the front end of the block label 60 adheres to the hexagonal bottle and separates the next block label 60 from the backing paper 61. When the front end block label 60 further adheres to the hexagonal bottle, the front end block label 60 and the next block label 61 are separated under the action of tension. 0 is broken at the breaking line 600, so that the next block label 60 can be pasted on the next hexagonal bottle; finally, the hexagonal bottle with the pre-label 60 enters between the limiting plate 2 and the rolling mechanism 3, and the rolling belt 30 can rotate with the hexagonal bottle during the rotation process, and the supporting roller 3214 can move inward and outward with the rotation of the hexagonal bottle, so that the rolling belt 30 can adapt to the diameter change of the hexagonal bottle when it rotates, and the label 60 can be tightly attached to the hexagonal bottle; therefore, the bottled bird's nest labeling machine can quickly and continuously complete the label 60 of multiple hexagonal bottles, and the work efficiency is high.
