Device for detecting stems in leaves and removing stems from leaves

Abstract

The invention relates to a device for detecting stems in leaves and removing the stems from the leaves and belongs to the technical field of tobacco detection. The device comprises a vertical main pipe which is communicated with a conveying pipeline, wherein the stems enter the vertical main pipe from the bottom and are discharged from the top; a detection pipe made of a transparent material is arranged on the middle part of the main pipe; a light source is arranged on one side of the detection pipe; a light-reflecting mirror for upwards reflecting horizontal light passing through the detection pipe is arranged on the other side of the detection pipe; a camera of which the lens is downward is arranged above the light-reflecting mirror; the signal output end of the camera is connected to the controlled end of a solenoid valve nozzle through a control circuit; the solenoid valve nozzle is connected with a high-pressure air source; an air outlet of the high-pressure air source is horizontally formed on one side of the main pipe above the detection pipe; and a removing branching passage is formed on the other side opposite to the main pipe. The device can automatically detect the stems in the leaves and remove the stems from the leaves; the production efficiency is obviously improved; the labor intensity is reduced; and the quality of raw materials for preparing tobacco products is guaranteed.

Description

technical field [0001] The invention relates to a detection device for tobacco stems contained in leaves, in particular to a detection and removal device for tobacco stems contained in leaves, which belongs to the technical field of tobacco detection. Background technique [0002] In the tobacco industry, the leaf stems cannot be directly used in the production process, and it will affect the storage and aging of raw materials. Therefore, the stem content rate in the leaves is a very important indicator in the leaf threshing and redrying process. The stem content in the leaves is high, and the content of stems and stems in the cut tobacco increases, which will lead to a decrease in the quality of the leaves, and the purity of the tobacco is not high, thereby affecting the quality of cigarette products and the operating efficiency of cigarette making machines. So the stems need to be removed. [0003] According to the applicant's knowledge, for a long time, the methods of de...
