Device for increasing baling density uniformity of threshed and re-dried tobacco leaves

Abstract

The invention provides a device for increasing baling density uniformity of threshed and re-dried tobacco leaves. The device is characterized by comprising an incoming material conveying device (3) with a primary homogenizing mechanism (2), a feeding belt conveyor (11) vertically spliced with the incoming material conveying device (3), a bin (12) arranged on a material falling port of the feeding belt conveyor (11), a secondary homogenizing device (1) arranged on the material falling port, a pre-pressing baling machine (14) arranged above the bin, a conveyor (15) used for conveying pre-pressed cigarette packets in the bin, a re-pressing baling machine (8) arranged behind the conveyor (5), a bundling device (9) arranged behind the re-pressing baling machine, and a control system (13) connected with the secondary homogenizing device (1). The invention has the advantages of increasing the density uniformity of a pre-pressing machine of a pre-pressing baling unit during baling tobacco billets, being beneficial to alcoholizing and stacking of the cigarette packets and reducing the mildewing risk of the cigarette packets.

Description

technical field [0001] The invention relates to the technical field of packaging equipment for threshing and redrying tobacco leaves in the tobacco industry. Background technique [0002] At present, in the threshing and redrying process and equipment at home and abroad, the density uniformity of the pre-pressed baler on the pre-pressed packing line is difficult to meet the national tobacco industry standard threshing and redrying process specification (YC / T146-2001) Article 5 The tobacco leaf packaging requirement of "uniform feeding to ensure that the density deviation (DVR) in the box (DVR) ≤ 10%" is not conducive to the alcoholization and stacking of cigarette packs. At present, the reciprocating feeding belt conveyor of the pre-pressing baler unit feeds in the front section Basically, the belt conveyor is used, and the material is not uniformed before the incoming material falls into the reciprocating feeding belt conveyor, resulting in uneven thickness of the material ...

[0002] At present, in the threshing and redrying process and equipment at home and abroad, the density uniformity of the pre-pressed baler on the pre-pressed packing line is difficult to meet the national tobacco industry standard threshing and redrying process specification (YC / T146-2001) Article 5 The tobacco leaf packaging requirement of "uniform feeding to ensure that the density deviation (DVR) in the box (DVR) ≤ 10%" is not conducive to the alcoholization and stacking of cigarette packs. At present, the reciprocating feeding belt conveyor of the pre-pressing baler unit feeds in the front section Basically, the belt conveyor is used, and the material is not uniformed before the incoming material falls into the reciprocating feeding belt conveyor, resulting in uneven thickness of the material in the width direction of the reciprocating feeding conveyor belt conveyor, which causes the material to flow from the reciprocating feeding conveyor belt conveyor. When falling into the material box of the pre-pressing baler, the thickness of the material layer is not uniform; the position of the reciprocating feeding conveyor belt conveyor drop hopper of the pre-pressing baler is equipped with a distribution plate for material equalization. Currently, there are three main methods of material equalization, namely imitation The swinging angle of the distribution plate of the three uniform feeding methods cannot be detected at any time according to the density detection of the rear section of the packaging line, such as the translational swinging distribution method of the Fez company, the fulcrum swinging distribution method of the Garbuio company, and the rotary feeding method of the Godly company. The output density data and the real-time adjustment of the flow rate of the incoming material in the previous section lead to large fluctuations in the density uniformity of the packaged tobacco billets
