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

The invention discloses a rotating tobacco strip online sampling and detecting device for a threshing and redrying plant. The device comprises a rotating ring-shaped sampling device, a tobacco strip transmission device, a tobacco strip detection device and a controller for controlling the above devices. A material discharge port of the rotating ring-shaped sampling device is arranged above the tobacco strip transmission device, a material discharge port of the tobacco strip transmission device is arranged above a material feeding port of the tobacco strip detection device, and a material discharge port of the tobacco strip detection device is provided with a material discharge belt. According to the device and the method, in an existing tobacco production assembly line, through adding a tobacco taking device and carrying out thinning process on a tobacco strip in a transmission process, finally a negative pressure blanking chamber is used to carry out the positioning of the tobacco strip, the positioned tobacco strip is collected through an image sensor, thus the tobacco strip image sensor can directly process the collected tobacco strip image, the working efficiency is greatly improved, and the intensity of working is reduced.
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 rotary 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, a...
