Problems solved by technology

However, the currently used frames are all designed for threshing, in order to tear off a small amount of tobacco leaves attached to the tobacco stems during the threshing process; this type of frame adopts a frame opening with rhombus openings , the opening between the diamond-shaped teeth is relatively large, and the difference between the length and length of the tobacco stem after passing through the frame is obvious
The leaf emergence rate after the first and second threshing has reached more than 86%. The frame of this structure cannot handle the actual situation that the amount of threshing leaves is greatly reduced and the tobacco stems are greatly increased.

Embodiment 1

[0020] Taking the processing of the upper tobacco leaves of Qujing 2 Yun 87B2F as an example, respectively adopting the prior art leaf threshing machine (using the frame bar of diamond-shaped opening) and the leaf threshing machine of the present invention to carry out the test, the results show: under the same beating speed, The rate of long stems from 25.4 to 50.8mm increased by 1.74%, the rate of long stems from 50.8 to 101.6mm increased by 5.99%, the rate of long stems larger than 101.6mm decreased by 9.04%, and the rate of leaves in the stem decreased by 3.56%.

Embodiment 2

[0022] Taking processing Qujing 2 Yun 87DC3F middle tobacco leaves as an example, respectively adopt the prior art leaf threshing machine (using the frame bar of diamond-shaped opening) and the leaf threshing machine of the present invention to carry out the test, the results show: under the situation of the same beating rotation speed, The rate of long stems from 25.4 to 50.8mm increased by 2.16%, the rate of long stems from 50.8 to 101.6mm increased by 7.25%, the rate of long stems larger than 101.6mm decreased by 11.27%, and the rate of leaves in stems decreased by 4.76%.

[0023] According to the same method as in Examples 1 and 2, the production test was carried out for one month. Statistics show that: after using the frame 5 with square holes 6, the percentage of tobacco stems smaller than 25.4mm is reduced by 3.88%, and the percentage of tobacco stems between 25.4 and 101.6mm is reduced by 3.88%. The rate of tobacco stems increased by 10.31%, the rate of tobacco stems la...

Abstract

The invention discloses a threshing device capable of improving cabo evenness. The threshing device comprises a feed port, a discharge port, a transmission roller, a threshing hammer and a frame fence. Square holes are longitudinally and transversely formed in the frame fence at intervals, and are not coincident with the boundary of the frame fence. The percentage of opening on the frame fence plane is larger than 46%. Furthermore, the square holes are the holes with the same standard, and the number of the holes in the frame fence is 149 per square meter. Holes in a frame fence in the prior art are diamond, the evenness of blades which are threshed is good through the diamond holes, but the capacity for screening cabo is poor. According to the threshing device, the diamond holes in the frame fence are changed into the square holes, and the size of the square holes and the arrangement of the holes are optimized. The square holes also can guarantee blade standards. The test shows that the improved frame fence is obviously better than the diamond hole frame fence, the length difference of the cabo which passes through the frame fence is reduced, the evenness is obviously improved, improvement on the standard degree of raw materials of the cabo is facilitated, the processing effect and comprehensive quality can be improved, and the demands of the tobacco primary process are met better.

Description

technical field [0001] The invention belongs to the technical field of tobacco processing equipment, in particular to a threshing device capable of improving the uniformity of tobacco stems. Background technique [0002] At present, domestic redrying enterprises usually use threshing machines to complete the separation of leaves and tobacco stems in the destemming process. The threshing machine uses a rotating hammer to cooperate with the frame to tear off the leaves on the tobacco stems, and obtain highly standardized tobacco leaves through the holes of the frame. In traditional tobacco production, tobacco stems are usually disposed of as waste. In order to adapt to the cigarette development trend of "harm reduction and coke reduction", tobacco stem raw materials are usually added in cigarette production. Compared with tobacco leaves, its physical structure is similar to that of tobacco leaves, but tobacco stems have lower tar content, strong fire-holding ability and low ...
