X-ray detecting device for finished cigarette pack bar-missing and cigarette bar box-missing

Abstract

The invention discloses an x-ray testing device and testing method of finished smoke lacking of single strip and strip lacking of package. The device is composed of single or multi-x-ray source, single or multi-x-ray detector, frame, position detector and data collection controlling system. X-ray source and detector are set on bilateral sides of tested smoke box separately and are one-to-one mapping to form several test units for testing smoke box or strip. Comparing testing value to standard value, smoke box or strip which testing value grater than standard value are eliminated by eliminating device. The device is non-contact no-wear test, which has merits of high accuracy, good security, stable and credible.
