This hot melt glue OPP labeling machine is a new type of rotary and continuous operation labeling machine. The equipment can automatically adjust the infeed and outfeed transmission of containers.

 

Containers conveyed by the conveyor belt are separated at a certain interval by the bottle separating screw according to the pitch of the star wheel. Then, the inlet star wheel transfers the containers to the container turntable, where they are fixed by the bottle pressing mechanism and the container mold seat, and start to rotate in the set manner.

 

When the container reaches the photoelectric eye detection position, the computer main controller controls the label feeding system to feed labels. After completing one label feeding action, the high-speed cutter cuts off one label. The adoption of the motion control system ensures the accuracy and stability of high-speed label feeding and cutting.

 

The cut label is sent to the glue application system. In this part, the system applies glue only to the leading and trailing edges of the label, which minimizes the consumption of hot melt glue.

 

When the glued label is rotated to the labeling position, it can be accurately and effectively applied to the container. Since the container is in a rotating state during the label conveying process, the label can be smoothly and tightly attached to the container. The glue strip at the end of the glue application can form a good label lap joint seal, completing one labeling process.
