Apparatus and method for on-line sampling and detecting of lifting type tobacco strip for threshing and redrying factory

Abstract

The invention discloses an apparatus for on-line sampling and detecting of a lifting type tobacco strip for a threshing and redrying factory, which comprises a sampling device, a tobacco strip conveying device, a tobacco strip detecting device and a controller for controlling the above devices, wherein the discharge opening of the sampling device is arranged above the tobacco strip conveying device, the discharge opening of the tobacco strip conveying device is arranged above the feeding opening of the tobacco strip detecting device, and the discharge opening of the tobacco strip detecting device is provided with a discharge belt. In the existing tobacco production line, a tobacco collecting device is added, and the tobacco is thinly processed in the conveying process. Finally, the tobaccois positioned by a negative pressure discharging chamber, and the positioned tobacco is collected by an image sensor, so that the image detection device of the tobacco strip can directly process theimage of the collected tobacco strip to greatly improve the working efficiency and reduce the working intensity.

Description

technical field [0001] The invention relates to the technical field of cigarette raw material processing, in particular to an on-line sampling detection device and method for lift-type sheet tobacco used in a threshing and redrying factory. Background technique [0002] At present, the current cigarette processing enterprises are focusing on the optimization and upgrading of equipment and technology in the threshing and redrying process. As an important processing link of tobacco raw materials, the structure of tobacco sheets processed by the threshing and redrying factory has seriously affected the structure of shredded tobacco in subsequent cigarette factories. , have a greater impact on the physical indicators and sensory quality of cigarettes. The sampling inspection process of the threshing and re-roasting plant is relatively complicated. Usually, the sampling points are collected manually after threshing, after wind separation, before re-roasting, and after re-roasting...

AI Technical Summary

Problems solved by technology

The sampling inspection process of the threshing and re-roasting plant is relatively complicated. Usually, the sampling points are collected manually after threshing, after wind separation, before re-roasting, and after re-roasting, and sent to special instruments for structural inspection. The labor intensity is high and the timeliness is poor.

[0003] For the inspection of sheet shape and structure, rebaking plants mostly use vibrating sieve. The current machine vision technology is becoming more and more advanced. It has gradually become a trend to use image CCD + software contour recognition method to detect sheet tobacco structure. The existing image detection equipment in the baking factory cannot be combined with the online detection of the production line due to its large size
