Description
Technical Field
The invention relates to the technical field of threshing machines in threshing and redrying links, in particular to a threshing system.
Background
With the continuous upgrading of the cigarette technology level and the rapid development of new cigarette products such as 'middle-end fine explosion', cigarette industry enterprises put forward new requirements on the quality of products in threshing and redrying links with homogenization processing as a core. The tobacco leaf structural index is used as one of important indexes for measuring the homogenization processing level, directly influences the filling capacity and the rolling effect of the tobacco shreds of cigarettes, and is the basis for stabilizing the quality of the cut tobacco. In recent years, domestic and foreign researches show that the optimal range of the tobacco size is 10-35 mm, because when the tobacco size is less than 10mm, the tobacco filling capacity is drastically reduced, and when the tobacco size is more than 35mm, the filling capacity is not obviously increased, and the efficiency of a cigarette machine is also affected. Therefore, the requirements of cigarette industry enterprises on the structural indexes of tobacco leaves after threshing are changed from the aspect of improving the large and medium piece rate to the aspect of reducing the large pieces and lifting the medium pieces.
The threshing principle of the existing threshing and redrying equipment is as follows: by utilizing the leaf characteristics and the difference of tissue structures at the joints of the leaves and the stems, tobacco leaves enter a threshing device after reaching certain technological conditions in the early stage, under the drive of a threshing roller rotating at high speed, under the action of centrifugal force, tobacco flakes and the tobacco stems are torn off under the action of friction and tearing, and when the size of the torn-off material on the circumference is close to or smaller than a certain size, the tobacco flakes and the tobacco stems escape from a discharge port, so that the purpose of threshing is realized.
In the existing threshing equipment, a threshing roller is arranged in a threshing device, a feeding hole of the threshing device is communicated with a blanking device, and the feeding hole is arranged at one end of the top of the threshing device; when the device works, the threshing roller rotates in a single direction and rotates to the threshing roller corresponding to the feeding hole, and the tangential direction of rotation of the threshing roller and tobacco leaves entering from the feeding hole are almost in the same direction, so that the tearing effect of the tobacco leaves in the threshing device is poor, the required purpose of 'reducing and lifting' cannot be met, the threshing roller rotating speed or the threshing machine set number can be increased, but the cost is obviously increased.
In addition, the existing threshing roller capable of rotating in one direction has the problem that tobacco scales are adhered to the surfaces of the movable cutters in the opposite rotation direction, the tobacco scales need to be cleaned in time, otherwise, threshing effects can be affected, and the existing threshing equipment needs to be cleaned frequently.
