Problems solved by technology

But the actual situation is very complicated. For example, after cutting the stem stick, its external dimension is very close to that of shredded tobacco, and its suspension speed is not much different from that of shredded tobacco. Moreover, shredded tobacco will curl up after drying and cooling, and even twist into a ball, causing The surface area of ​​cut tobacco is reduced and the suspension speed is increased, which all increase the difficulty of winnowing and destemmi

Embodiment Construction

[0009] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings. The working principle of the present invention is to use a multi-stage winnowing device to carry out multiple winnowing for large-flow shredded tobacco. attached figure 1 In the embodiment of the present invention, it is two-stage winnowing, and its working principle is: after the shredded tobacco of large flow enters the winnowing device, firstly carry out the first winnowing, and in the first winnowing process, control the first winnowing mechanism 60% to 90% of the shredded tobacco is selected in the first winnowing. Because the wind speed in the first-level winnowing device is relatively low, the possibility of the stem being selected is relatively low, which can ensure that the shredded tobacco is selected The content of the signed quantity meets the product quality requirements. Then carry out the second winnowing ...

Abstract

The invention discloses a multistage pneumatic separation device for eliminating stems from tobacco shreds, belonging to the technical field of cigarette equipment. The device comprises at least two level pneumatic separation mechanisms, and each pneumatic separation mechanism comprises a pneumatic separation box, a rapid leather belt and a blower, wherein an air outlet of the blower is arranged at the lower part of the pneumatic separation box, and a feed opening of the rapid leather belt is arranged on an air outlet of the blower; a filling engine comprising a big wheel and a small wheel isarranged below the front wall of the pneumatic separation box; an air and material separating box is also arranged in front of the last level pneumatic separation box; an exhaust manifold on the air and material separating box is communicated with a plurality of branch pipes among which one is connected with the atmosphere through a dust collector, and other branch pipes are respectively communicated with the air inlet of each level air circulator. The multistage pneumatic separation device has reasonable design, simple structure and convenient operation, can accurately separate tobacco shredsand stems, ensures the production quality and is particularly suitable for being applied on a large capacity production line.

Description

technical field [0001] The invention belongs to the technical field of cigarette equipment, and relates to a multi-stage winnowing device capable of removing stems with high precision from large-flow shredded tobacco. Background technique [0002] In the cigarette production process of the prior art, in order to improve the product quality, the stem sticks mixed in the shredded tobacco must be removed. However, removing the stem sticks from the shredded tobacco has always been a difficult problem in cigarette production. Removing stem sticks from shredded tobacco generally adopts the method of winnowing, which utilizes the difference in the suspension speed of shredded tobacco and stem sticks in the airflow to carry out winnowing. The suspension speed mentioned here refers to the speed of wind required for the material to be in suspension. Theoretically speaking, the suspension velocity of shredded tobacco is small, and the suspension velocity of stem sticks is high, so they...
