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

Embodiment 1

[0037] Embodiment 1: as Figure 4 , Figure 5 Shown, a kind of tobacco leaf spreading that the present invention relates to, flattening, the method for single-layering, operation process is as follows:

[0038] Tobacco leaves enter the material dispersion chamber 2 at a speed of 2m / s from the belt surface of the feeding belt conveyor 1, which can be 1-3m / s, and enter the material dispersion chamber 2 in a direction at an angle of 20° with the material dispersion chamber 2 horizontal direction;

[0039] Tobacco leaf passes through the speed of speed 5m / s in material dispersion cavity 2, and this speed can be in

[0040] The updraft between 3m / s-6m / s removes the heavy impurities 14 through the outlet of the impurities below, and at the same time loosely conveys the remaining tobacco leaves into the material-gas separation air duct 4 .

[0041] Due to the narrowing of the cross-section of the tobacco leaves in the material-gas separation duct 4, the material-gas mixture is accel...

Embodiment 2

[0043] Embodiment 2: as Figure 1 to Figure 5 As shown, a device for paving, flattening and single-layering of tobacco leaves includes a frame, a feeding belt conveyor 1, a discharging belt conveyor 7, and an air flow system, and is characterized in that the end of the feeding belt conveyor 1 is connected to Material dispersion chamber 2, the bottom of the material dispersion chamber 2 is equipped with an air distributor 3 connected to the air flow system, the upper part of the material dispersion chamber 2 is connected to the material-air separation air duct 4, and the middle part of the material-air separation air duct 4 is equipped with a negative pressure monolayer The sieve cylinder 5 and the upper part of the material-gas separation air duct 4 are connected to the negative pressure suction duct 6, and the side of the negative-pressure single-layer sieve cylinder 5 is provided with a discharge port on the side wall of the material-gas separation air duct 4, and the dischar...

Abstract

The invention relates to the field of tobacco processing, and relates to the control technology of the tobacco form, in particular to a tobacco online spreading, flattening and monolayer-conveying method and equipment. Tobacco is accelerated in a material-air separation air duct, then the overlapped and wrapped tobacco is spread and flattened through positive pressure and zero pressure conversion of a negative pressure monolayer screen drum, the tobacco is handed over to a high-speed belt conveyor, and the belt speed of the high-speed belt conveyor is larger than or equal to the discharge speed of the screen drum in order to prevent the monolayer tobacco from being overlapped again; after the tobacco is handed over to the high-speed belt conveyor, by applying equal-belt-speed compressed air, the tobacco is attached to the belt surface of a high-speed belt and conveyed to a link needing tobacco detection along with the high-speed belt, wherein the angle between the equal-belt-speed compressed air and the belt running direction is an acute angle. According to the omni-bearing dead-angle-free method for exposing debris, green blocks and mildew spots in the tobacco under a detection device, the defect that in traditional photoelectric detection, during tobacco conveying, the debris, the green blocks and the mildew spots cannot be detected due to tobacco wrapping and overlapping can be avoided.

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...
