Description
Technical Field
The utility model relates to a tobacco processing field especially relates to an automatic take out stalk and divide stalk device.
Background
In the cigarette manufacturing process, it is very important to perform related detection on materials, for example, the cut stem content detection needs to be performed on tobacco leaves in the same batch, and in order to realize the cut stem content detection, the tobacco leaves need to be subjected to stem extraction and stem separation before the detection.
At present, the following two methods are adopted for carrying out the stem drawing and separating operation:
(one) threshing method
The method comprises the steps of adopting threshing air separation equipment occupying relatively large space, crushing a tobacco leaf sample to be detected to be smaller in particle size, separating crushed tobacco flakes and tobacco stems through an air separation box, and finally, manually collecting the tobacco stems and then screening out coarse stems and fine stems by adopting a multi-layer screening device.
On the background that the tobacco industry has higher and higher requirements on the detection of process quality indexes, the real-time control, the linearity, the accuracy and the like, the method highlights the following defects: (1) the smashing operation is relatively rough, so that broken tobacco flakes and tobacco stems are scattered too much, and the stem and leaf separation effect is influenced; (2) the damaged detection sample is difficult to be mixed back into the original formula for continuous use, so that the consumption of raw materials is increased; (3) the stem content detection is carried out after the stem content detection is carried out by using the method, the detection result is influenced by the stability of a plurality of factors such as threshing parameters, air classification parameters, screening parameters and the like, and particularly, the process of collecting and screening thick and thin stems is also easily influenced by manual operation; (4) the equipment structure is complicated, and the maintenance work is loaded down with trivial details.
(II) hand tearing method
The method is to separate the tobacco stems and leaves by manually tearing, and then manually distinguish the tobacco stems with different thicknesses by adopting tools such as calipers and the like. Compared with the threshing method, the method is relatively more precise, and avoids losing a part of available tobacco stems which are used for calculating the stem content rate due to the crushing process. However, the method has the disadvantages that the manual efficiency is low, the manual influence factors are also mixed, and the tobacco leaves are remained and further the subsequent detection is influenced because the pure manual operation is difficult to avoid incomplete stripping.
