AI Technical Summary

Technical Problem

The existing bottle preform detection device is difficult to accurately detect bottle preforms produced by double-row multi-cavity bottle blowing machines. Especially when the bottle preforms rotate at a fast speed, there is a problem of overlapping incomplete detection, resulting in poor detection accuracy.

Method used

A double-row multi-cavity preform counting and detection device is designed. By setting the first and second preform holding mechanisms side by side on the turntable, and installing a reflector and photoelectric sensors in the annular area, separate counting and detection of the inner and outer preforms is realized.

Benefits of technology

This device can greatly improve the accuracy of bottle preform counting and the accuracy of quality control. It has a simple and compact structure and is easy to install and maintain.
