Intelligent tobacco stalk detecting and removing device and working method thereof

Abstract

The invention discloses an intelligent tobacco stalk detecting and removing device and a working method thereof. The device comprises a shell, a conveying belt, an intelligent detection identification module and an automatic removal module, wherein the automatic removal module comprises a soft X-ray generating tube and a line scanning soft X-ray receiving sensor, the soft X-rays sent by the soft X-ray generating tube cover the cross section of the conveying belt, and the soft X-rays penetrate the conveying belt and are received by the line scanning soft X-ray receiving sensor; and the line scanning soft X-ray receiving sensor and the soft X-ray generating tube are both communicated with a main control module. The device realizes the automatic screening separation of tobacco leaves with stalks, of which the stalk-containing rate exceeds the set value, and qualified tobacco leaves, makes the tobacco leaves with stalks, of which the stalk-containing rate exceeds the set value, conveniently subjected to aftertreatment; and moreover, the device also has the advantages of guaranteeing and improving the quality of cigarette, saving manpower and improving operating efficiency.

Description

technical field [0001] The invention relates to a device for detecting and removing tobacco stems in the technical field of tobacco processing equipment, in particular to an intelligent device for detecting and removing tobacco stems using soft X-rays for detection and identification and a working method thereof. Background technique [0002] In the tobacco processing link, tobacco sheets and tobacco stems need to be processed separately, and the "leaf stem content rate" in tobacco leaves (including tobacco sheets) is an important technical index to measure the quality of tobacco sheets. Tobacco stems in high-quality tobacco leaves are impurities and need to be removed. Reducing the stem content in leaves can effectively improve the purity of tobacco leaves and improve the quality of tobacco sheets. The currently widely used stemmed tobacco leaf screening and rejecting devices mainly include winnowing + reprocessing devices and manual screening and impurity removal devices. ...

AI Technical Summary

Problems solved by technology

The winnowing + reprocessing device is mainly used for the separation and processing of leaf stems. It is suitable for occasions where the shape of the tobacco leaves is large and the stems contained in the leaves are thick. Since its floating rate is close to that of pure tobacco leaves, the device cannot realize the screening and rejection of small pieces of tobacco leaves with small stems and stems

Manual screening and removal of impurities is generally used in the pretreatment section of the silk thread. Although this device can effectively identify, screen and remove small pieces of tobacco with small stems and diameters, it requires a lot of manpower. The stalk content rate is only 1-3%, and manual screening of all tobacco leaves is required, so the work efficiency is low
