Description

Technical Field

[0001] The invention belongs to the technical field of tobacco leaf production and processing, and in particular relates to an automatic grabbing and feeding device for tobacco leaf redrying. Background Art

[0002] Tobacco leaf redrying is a secondary drying process after the tobacco leaves are picked and dried initially. This process is mainly to further accurately control the moisture content in the tobacco leaves and improve the quality and storage stability of the tobacco leaves. Redrying can improve the physical properties of the tobacco leaves, making them softer and easier to process and roll. At the same time, the redrying process can remove some bad odors in the tobacco leaves and enhance the aroma and flavor of the tobacco leaves. In addition, redrying can also help kill microorganisms in the tobacco leaves, reduce pests and diseases, and extend the shelf life of the tobacco leaves. When redrying tobacco leaves, an automatic grabbing and feeding device is needed to place the tobacco leaves on a conveyor belt, such as the existing public document CN220501974U-A tobacco leaf automatic grabbing and feeding device.

[0003] An existing disclosed automated tobacco leaf grabbing and feeding device adopts an adjustable pin-embracing structure, which can stably and accurately grab tobacco leaves onto a conveyor line.
