Method and device for spreading, flattening and single-layering tobacco leaves

Abstract

The invention relates to the field of tobacco processing, and relates to a technology for controlling the shape of tobacco leaves, in particular to a method and equipment for online spreading, flattening, and single-layer transportation of tobacco leaves. Tobacco leaves are accelerated in the material-gas separation air duct, and then the overlapped and wrapped tobacco leaves are unfolded and flattened by the positive pressure and zero pressure conversion of the negative pressure single-layer sieve cylinder, and then transferred to the high-speed belt conveyor, the belt speed of which is greater than or equal to The discharge speed of the sieve cylinder is to prevent the re-stacking of the single-layered tobacco leaves; after the tobacco leaves are transferred to the high-speed belt conveyor, the equal-speed pressure air with an acute angle to the belt running direction is applied to make the tobacco leaves adhere to the high-speed belt surface and follow This method of exposing the sundries, green blocks, and mildew spots in the tobacco leaves to the detection device in an all-round way without dead ends can avoid the sundries, green blocks, and mildew spots in the traditional photoelectric detection when transporting tobacco leaves. Defects that cannot be detected due to the wrapping and overlapping of tobacco leaves.

Description

technical field [0001] The invention relates to the field of tobacco processing, and relates to a technology for controlling the shape of tobacco leaves, in particular to a method and equipment for online spreading, flattening, and single-layer transportation of tobacco leaves. Background technique [0002] In the production of cigarettes, the purity of cut tobacco has always been a difficult problem for various technicians. Since the tobacco leaves required in the cigarette industry have to go through processes such as harvesting, purchasing, threshing and re-baking, and shredding, the control of each link is not good enough. Improper storage will produce non-smoky debris such as hemp silk, feathers, straw, stones, etc., and will also be accompanied by low-grade tobacco leaves such as green smoke and moldy smoke, which will seriously affect the quality of cigarette products. Therefore, improving the purity of tobacco leaves is a key link in the process of tobacco leaf proce...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to solve the problem that the existing technology cannot spread, flatten, and single-layer tobacco leaves, so that the non-smoke impurities and low-grade tobacco leaves cannot be accurately removed, and it provides a method that uses airflow to loosen the tobacco leaves. Method and equipment for stably outputting tobacco leaves in a single layer after being spread and flattened by the combined action of negative pressure conversion and rotating screen drum friction force
