Abstract
A system for preventing overflow of adhesive applied to a PET rolling film includes a drive unit, a detection unit, and a processing unit. The detection unit detects whether UV adhesive spread on a PET film flows out to limit lines on the PET film. The detection unit generates trigger signal upon detecting that the UV adhesive on the PET film flows to any of the limit lines, and then transmits the trigger signal to the processing unit. The processing unit controls the drive unit to accelerate a rotational speed of a guide roller for the PET film upon receiving the trigger signal from the detection unit, so as to accelerate a moving speed of the PET film.

A system for preventing overflow of adhesive applied to a polyethylene terephthalate (PET) rolling film comprising:
- a drive unit, a detection unit, and a processing unit;
- wherein the detection unit detects whether ultraviolet curable adhesive (UV adhesive) on a PET film flows to two outer limit lines on the PET film, and the detection unit generates a main trigger signal upon detecting that the UV adhesive on the PET film flows to either of the two outer limit lines, and then transmits the main trigger signal to the processing unit;
- and
- wherein the processing unit controls the drive unit to accelerate a rotational speed of a guide roller upon receiving the main trigger signal from the detection unit, so as to accelerate a moving speed of the PET film.
A method for preventing overflow of adhesive, the method comprising:
- detecting, by a detection unit, whether ultraviolet curable adhesive (UV adhesive) on a polyethylene terephthalate (PET) film flows to two outer limit lines on the PET film;
- generating, by the detection unit, a main trigger signal upon detecting that the UV adhesive on the PET film flows to either of the two outer limit lines, and then transmitting the main trigger signal to a processing unit;
- and
- controlling, by the processing unit, a drive unit to accelerate a rotational speed of a guide roller upon receiving the main trigger signal, so as to accelerate a moving speed of the PET film.
