Description

Technical Field

[0001] The utility model relates to the technical field of tobacco leaf processing, in particular to a high-efficiency leaf threshing, re-drying and separating device. Background Art

[0002] There are many factors that affect the quality of leaf threshing. Due to the instability of incoming materials, poor uniformity, and large differences in tobacco leaves, when using the traditional single leaf threshing mode, the processing differences are obvious, resulting in diverse leaf structures and shapes after threshing, and severe fragmentation.

[0003] A method for beating and re-baking tobacco leaves is proposed in the patent with publication number CN112890263B, which includes a cutting roller, a slicing net, a device body, a sample return piece, a compression spring, a spring, a feed guide plate, a discharge guide plate, and a tobacco pressing chain. The leaf cutting device has cut the tobacco leaves into the size and shape required by the slim cigarette industry, and avoids the appearance of long strips and willow-leaf-shaped tobacco leaves; and, through this process, the size and shape of the tobacco leaves can be controlled, which can effectively improve the consistency of the tobacco structure and the stability of the indicators in the silk-making process. Before beating the leaves, the raw tobacco leaves have been divided into three parts, among which the hexagonal leaves without the main vein are no longer beated for stemming. The leaves are separated, and the hexagonal leaves with main veins entering the leaf threshing process are regular hexagonal shapes. This regular shape is easy to loosen, avoid mutual entanglement, and easily separate the stems and leaves, thereby reducing energy consumption. The hexagonal leaves without main veins are separated and no longer need to be repeatedly threshed, avoiding tearing in the leaf threshing process, thereby effectively reducing the tobacco leaf crushing rate, improving production efficiency, reducing production costs, effectively controlling the shape and size of the largest piece of finished tobacco leaves and the uniformity of the finished tobacco leaf structure, effectively reducing the secondary crushing of tobacco leaves, reducing energy consumption, and improving economic indicators. It can well meet the new cigarette process requirements of industrial enterprises, but there are still the following problems in this patent:

[0004] The existing tobacco leaf threshing assembly is realized by manually adjusting the installation position of the frame in the machine body, which will lead to a long production pause, reduced efficiency, labor-intensive, time-consuming and labor-intensive work.
