Device for improving charging front blade size uniformity and method thereof

Abstract

The invention discloses a device for improving charging front blade size uniformity and method thereof. The device comprises a vibrating screen arranged on a rack, the vibrating screen is provided with a first layer screen, a second layer screen and a third layer screen from top to bottom, and the meshes of all the screens are gradually reduced from top to bottom; a charging device is arranged above one end of the vibration screen, all the screens at the other end of the vibration screen are provided with a discharging port; a plurality of loosing rollers are arranged between the charging device and the first layer screen in parallel, and the axis of the loosing roller is arranged along the width direction of the vibration screen. The invention can effectively improve uniformity of humidifying and charging of subsequent process and also effectively reduces shred growth rate of tobacco shred after being cut.

Description

Technical field: [0001] The invention relates to a device and a method for improving the size uniformity of blades before feeding. Background technique: [0002] At present, the tobacco leaves used in cigarette factories are re-cured tobacco leaves, and large pieces (greater than 25.4mm) in the tobacco leaves 2 blades) are too many, according to statistics, the large-scale rate is about 55%. On the silk production line, if the rate of large pieces is too high, there will be two problems: [0003] 1. The leaves are easy to fold, which will have a negative impact on the uniformity of the leaves to absorb water and feed liquid; [0004] 2. The length uniformity of shredded tobacco after cutting is poor, and there are too many filaments, which is easy to produce entanglement and agglomeration, which has a negative impact on the control of moisture content in shredded tobacco and the quality of cigarette rolling. [0005] At present, several methods have been proposed to solve...

AI Technical Summary

Problems solved by technology

[0003] 1. The leaves are easy to fold, which will have a negative impact on the uniformity of the leaves to absorb water and feed liquid;

[0004] 2. The length uniformity of shredded tobacco after cutting is poor, and there are too many filaments, which are prone to entanglement and agglomeration, which will have a negative impact on the control of moisture content in shredded tobacco and the quality of cigarette rolling

[0006] The above two types of technologies can solve the problem of excessive tobacco filaments to a certain extent, but fail to solve the problems of moisture content and uneven application of feed liquid caused by too large leaves
