Look at the bottle type, whether it is plastic bottle or glass bottle (excluding irregular bottles). Pay attention to where its center of gravity is. It is emphasized that glass bottles (such as beer bottles) rotate by themselves when they come out, which will accelerate at high speed. When they encounter excessive plates, uneven synchronous chain of bottle conveying at the exit, speed mismatch, improper adjustment of guardrail gap, etc., it is easy to pour bottles. Adjust the method, re-correct the common causes of bottle falling, and check whether the excessive plate at the star wheel is excessively worn and replaced, and level it with a leveling rod to be on the same level as the bottle tray and bottle outlet chain plate (bottle conveying chain). If the upper and lower pieces of the star wheel are unevenly worn, they will appear non-vertical, and the bottle will intensify its swing when it rotates. When it leaves the star wheel, it will hit the top of the exit guardrail, instead of falling forward, it will fall backward. The bottle comes out with a rotation stop (some are rotation stop wheels and some are rotation stop belts) provided that the trademark cannot be damaged.

Crance suggested not to drive the labeler to its designed maximum speed. For example, for a labeler with a speed of 5,/hour, the maximum speed should not exceed 45,, and the maximum speed of 45, should be 4,. Constant speed and continuous operation can ensure the labeling quality and efficiency, and reduce the bottle explosion in the labeling process to reduce the accidental damage to the labeling machine.
