Waste cigarette pneumatic separation device and cigarette separation system

Abstract

The invention relates to a waste cigarette pneumatic separation device and a cigarette separation system. The waste cigarette pneumatic separation device comprises an air bellow and an air blowing device. A partition plate is arranged in the air bellow to divide an inner cavity of the air bellow into a first pneumatic separation cavity, a second pneumatic separation cavity and a pneumatic separation channel. The air bellow is provided with a feed inlet for achieving feeding from the first pneumatic separation cavity. An air flow port of the air blowing device faces towards the feed inlet. Air flow flows through the pneumatic separation channel in the feeding direction to enter the second cavity. In the pneumatic separation process, defective or waste cigarettes falling into the air bellow from the feed inlet are blown to be dispersed under the effect of pneumatic separation air flow, and air flow continues to be flow to drive the defective or waste cigarettes to flow along the pneumatic separation channel. The first partition plate achieves a blocking effect, and defective or waste cigarettes in various states are blocked to fall into the first pneumatic separation cavity. Cut tobaccos and paper scraps are relatively light and continue to move along the pneumatic separation channel rather than being blocked by the first partition plate and falling into the second pneumatic separation cavity, accordingly, pneumatic separation for defective or waste cigarettes is achieved, the pneumatic separation effect is good, production efficiency is high, and the cost is low.

Description

technical field [0001] The invention relates to the technical field of cigarette production and processing, in particular to a waste smoke winnowing device and a cigarette sorting system. Background technique [0002] According to statistics, during the rolling process of cigarettes, the weight of defective / waste cigarettes caused by factors such as short ends, loose ends, unstable weight, and running strips is about 0.5% of the total production. If the annual output of a China Tobacco Industrial Company is If the calculation is 2 million boxes, then the defective / waste cigarettes can be converted into finished products of about 10,000 boxes every year. According to relevant test results, it is shown that the whole shredded tobacco of the current defective / waste cigarettes is between 40% and 60%, and the shredded tobacco recovery rate is low, resulting in a large amount of shredded tobacco waste and economic loss. [0003] The current air separation device for waste smoke c...
