Label positioning mechanism

A label positioning mechanism, comprising:

• a conveying mechanism for conveying a plurality of bottles in a conveying direction;
• a label dispensing mechanism disposed on a side of the conveying mechanism and having a label dispensing side for outputting a plurality of labels in the conveying direction;
• a first labeling mechanism disposed together with the label dispensing mechanism on the same side of the conveying mechanism and positioned proximate to the label dispensing side, wherein the first labeling mechanism has a first tight-fitting winding belt and a first base for winding the first tight-fitting winding belt, the first tight-fitting winding belt having a transmission direction parallel to the conveying direction, the transmission direction facing a side of the conveying mechanism;
• and
• a second labeling mechanism disposed on another side of the conveying mechanism, opposing the first labeling mechanism, and having:
• a second tight-fitting winding belt having a transmission direction opposite to the conveying direction, the transmission direction facing a side of the conveying mechanism, wherein the first tight-fitting winding belt and the second tight-fitting winding belt come into contact with each other to rotate the bottles;
• a second base for winding the second tight-fitting winding belt;
• a second driving unit located on the second base and operatable to transmit the second tight-fitting winding belt;
• a second adjustment unit for adjusting a height of the second base relative to the conveying mechanism;
• and
• a third adjustment unit for adjusting a distance between the first and second bases;
• wherein a conveying speed of the conveying mechanism, a dispensing speed of the label dispensing mechanism, a transmission speed of the first tight-fitting winding belt, and a transmission speed of the second tight-fitting winding belt are adjustable according to a diameter of the bottles and a specific angle of rotation of the bottles.
