Description

Tobacco storage cabinet discharge anti-breaking loose device

technical field

The invention relates to the technical field of tobacco processing, in particular to an anti-breakage and loosening device for discharge of tobacco storage cabinets.

Background technique

Existing tobacco companies need to store materials such as tobacco stems, tobacco leaves, and shredded tobacco during the production process, so that they can achieve the purposes of mixing materials, buffering, storage, alcoholization, blending and feeding penetration, infiltration to balance moisture, and meeting process requirements.

The storage cabinet currently used includes a column, left and right side panels, a discharge port baffle and a tail baffle, a trough-shaped cabinet composed of an upper part for the feeding part, and a lower part for the storage and discharge parts. There is a material-feeding crane on the top of the cabinet, the bottom plate is a material-bearing belt for storing and conveying materials, and a raking licker-in roller is provided at the material outlet.

Among them, the material-laying crane and the belt conveyor are integrated in the feeding part, and the direction of the running of the driving and the running of the belt can be the same or reverse. The conveying bottom belt for the bottom discharge is composed of two shoulder chains supporting the grooved chain plate, and the chain plate is equipped with a material carrying belt. The conveyor or conveying crane puts the material on the belt of the material spreading vehicle, and the material spreading vehicle directs the motor and reducer through electrical control to make it reciprocate on the guide rail of the storage cabinet opening from the head to the tail of the storage cabinet. The material is spread evenly on the bottom belt layer by layer, and this is repeated until the material in the storage cabinet reaches the set storage thickness.

When discharging, start the conveying bottom belt deceleration motor and rake licker-in deceleration motor, and drop the material in the storage cabinet to the next level conveyor through the discharge port. The speed of the output material can be adjusted by frequency conversion according to the flow requirements of the process path The speed controller is implemented. Since the material is stored with a certain thickness and will agglomerate under pressure, in order to avoid the phenomenon of material clogging caused by the agglomeration and collapse of the material, the discharge port is required to be evenly and loosely discharged. The outlet for storing materials is fixed with a loose mechanism composed of a group of raking licker-in rollers. The number of rake shafts and the length of the rake sticks of the rake licker-in roller are determined by the height section of the material. Generally, it is arranged in three (or two) upper, middle and lower steps.

However, since there are three rollers with rake teeth in front of the material discharge—the rake licker-in roller, it completely blocks the material outlet like a roadblock. Although it plays the role of loose matter, it also prevents all materials from being damaged by rake teeth when they are discharged, causing their structure to be damaged and broken. Causes of crushing: First, the direction of rotation causes the problem of forward and reverse mixing of materials. The loose material is rotated by the roller shaft and the rake stick must be pushed upwards. When the rake teeth of the lower roller shaft move the material upwards, the adjacent middle roller shaft under the lower part squeezes the material inward and the rake teeth repeatedly stir the material. The roller shafts move towards each other while the materials move relative to each other. The second is that the multi-layer arrangement of the rollers leads to the problem of repeated mixing of materials. The material is first loosened by the rake teeth on the upper layer, and the rake teeth are stirring the material before the material is delivered out of the rotation diameter of the rake teeth, and at the same time, part of the material falls to the middle roller shaft layer and continues to stir. The material at the middle roller shaft position will be raked and stirred, and will fall to the lower roller shaft layer and continue to stir again until the bottom belt of the conveyor sends the material out of the discharge port to avoid damage. The third is that the speed of the raking licker-in roller matches the linear speed of the bottom belt conveying, which leads to the problem of continuous stirring of the material. The slow rotation of a single raking licker-in roller will cause the compacted materials that are in contact with the rake sticks to rotate and cannot be loosened, and the agglomerated materials will cause material blockage; if the raking roller rotates too fast, it will damage the materials and cause crushing. The speed of raking licker-in roller meets the conveying speed of the bottom belt, and the phenomenon of repeated stirring of materials appears. Some equipment manufacturers and equipment users have made modifications and experiments to adjust the speed of the two to match, change the arrangement of the rake teeth and the shape of the rake stick, but it is basically futile to improve the whole yarn rate and reduce the crushing rate.

The material is not harrowed out by the rake roller, but is dug out through the limited cross-section of the rake stick in the material storage pile. The loose method is also positive and negative stirring, repeated stirring, and continuous stirring. The material is broken: first, it is directly broken and broken, and second, it is not completely broken and damaged to reduce the processing resistance, which increases the breaking rate for the subsequent processes of wire feeding, wind transportation, coiling and other processes. The generation of dust pollutes the production environment, the rate of broken filaments increases, the rate of whole filaments decreases, the filling value decreases, and the rate of filament consumption increases, resulting in increased manufacturing costs. And seriously affect the intrinsic quality of cigarettes.
