Abstract

The invention discloses a device for the offline and online screening of cut tobacco from removed stem slivers of a cigarette maker. The device a left side wallboard and a right side wallboard, the left and right side wallboards are fixed on a baseboard respectively, an airflow channel fixedly arranged on the baseboard is arranged among the left and right side wallboards and the baseboard, the airflow channel has a segment of a continuous Z-shaped separation channel, the side surface of the upper half portion of the continuous Z-shaped separation channel is provided with a funnel communicated with the continuous Z-shaped separation channel, and the side surface of the lower half portion of the continuous Z-shaped separation channel is provided with a gas inlet communicated with the continuous Z-shaped separation channel; the airflow channel is provided with a cut tobacco rotation air-valve and a stem sliver rotation air-valve, and the tail end of the airflow channel is connected with a tapered connecting pipeline; the lower portion of the cut tobacco rotation air-valve is correspondingly provided with a cut tobacco collection tank movably connected to the left and right side wallboards, the lower portion of the cut tobacco collection tank is provided with a power transmission system fixed on one of the left and right side wallboards, and the cut tobacco rotation air-valve and the stem sliver rotation air-valve are respectively connected with the power transmission system; and the cut tobacco rotation air-valve, the stem sliver rotation air-valve and the funnel are fixed on the left and right side wallboards respectively.

Description

technical field [0001] The invention relates to a device for separating and recovering tobacco, in particular to a device for single-machine online screening of shredded tobacco from removed stems in a cigarette machine. Background technique [0002] At present, during the production and operation of the cigarette machine, in the process of conveying shredded tobacco by the wire feeder and separating the stems from it, the phenomenon of wires in the stems inevitably exists. When there is a stem in the shredded tobacco, it will pierce the cigarette paper wrapping the shredded tobacco on the surface of the cigarette, resulting in appearance quality defects and air leakage. In order to fully remove the stem sticks in shredded tobacco as much as possible, it is often necessary to increase the removal amount of stem sticks, which correspondingly increases the silk content in the stem sticks. Currently widely used PROTOS70 and other types of cigarette makers, due to the relativel...

AI Technical Summary

Problems solved by technology

[0005] 1. The power consumption is relatively large, and the fan needs a large-power motor, and the two stem discharge devices (actually air valves) need a motor, that is, there are three motors in total, which makes the energy consumption larger

[0006] 2. It occupies a large area, and the whole equipment is placed close to the equipment, which requires a large placement area, especially the fan needs a base, which must be fixed on the ground, needs to be installed with protective devices, and measures to reduce noise must be taken. The wind is not allowed to be discharged into the production site environment, and the fan exhaust pipe needs to be connected to the dust discharge pipe. If this accessory equipment is large, it will affect the appearance of the production area and the surrounding logistics channels

[0007] 3. The process is rough, and only uses the simple principle of air suspension. Only one air suspension separation is carried out on the stem sticks containing silk. It is almost impossible to separate the shredded tobacco that is attached or entangled on the stem sticks. This part of the shredded tobacco will be directly After the separated shredded tobacco enters the box connected to the fan, due to the suction effect of the fan, a considerable part of the shredded tobacco will be sucked away by the fan and discharged.

This part of shredded tobacco will be discharged together with the smoke and then discarded to form waste
