Description

Technical Field

[0001] The present application relates to the technical field of tobacco production, and in particular to a device for detecting the thickness of a tobacco leaf web. Background Art

[0002] In the tobacco production process, automation equipment plays an important role. Common automation equipment includes tobacco leaf processing equipment, tobacco production equipment, tobacco packaging equipment, tobacco quality inspection equipment and tobacco storage equipment. These equipment can improve production efficiency and ensure product quality.

[0003] In the process of tobacco leaf redrying, a leaf redrying machine is usually needed. The leaves are transported to the leaf redrying machine by a belt conveyor for the redrying process. However, when tobacco leaves with different material layer thicknesses enter the leaf redrying machine, the flow rate and baking uniformity of the leaf redrying machine will change, affecting the quality of tobacco leaf processing and production. Therefore, when redrying tobacco leaves, it is necessary to detect the thickness of the tobacco leaf net.

[0004] At present, the thickness of tobacco leaves is mostly detected by industrial cameras. The actual thickness of tobacco leaves is calculated by computer based on the tobacco leaf thickness pictures taken by industrial cameras, and then the feeding speed is adjusted according to the actual thickness of tobacco leaves. However, in the actual production process, due to the influence of moisture and dust emitted by tobacco leaves, the lens of industrial cameras is easily contaminated, resulting in inaccurate detection and deviation in measurement results. At the same time, industrial cameras are mostly installed in fixed positions, which is not convenient for detecting the thickness of tobacco leaves at various positions and guiding the thickness control of the material layer.
