Tobacco pretreatment automatic diluting and sorting device

Abstract

The invention discloses a tobacco pretreatment automatic diluting and sorting device. The device comprises a mounting base, a motor, rotary arms, a mounting plate, stirring wheels, a retainer plate, a feed collet, a feed collet driving device, a slide base, and a slide base driving device. The mounting plate is arranged in the middle of the mounting base, the several rotary arms are symmetrically arranged on the mounting plate in the longitudinal direction, the rotary arms are in transmission connection with the motor in the rear portion of the mounting base, free ends of the rotary arms are provided with stirring wheels respectively, and all the stirring wheels are in clearance fit with each other; the slide base driving device and the slide base are arranged at the two ends of the mounting base respectively, the slide base driving device is connected with the slide base, the slide base is in movable coordination with the mounting base, the slide base is provided with the feed collet driving device, the feed collet driving device is connected with the feed collet, and the retainer plate is arranged in front of the stirring wheels through a support. A method of clipping and delivering tobacco stems is adopted to deliver small strands of tobacco into a stirring wheel groove opening, the tobacco which is diluted can be well separated, the effect of dividing the tobacco into single strands is achieved, the spacing between the tobacco stems keeps coincident, the operation is convenient, the process of automatic loading, sorting, and feeding is completed, and the sorting efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of tobacco leaf selection and separation equipment, and in particular relates to an automatic thinning and sorting device for tobacco leaf pretreatment with simple structure and convenient operation. Background technique [0002] When processing leaf crops such as tobacco, it is necessary to classify and select the leaves to facilitate the processing of subsequent equipment, thereby improving the efficiency and quality of production and processing. [0003] In order to realize the automatic grading of large-leaf crops (such as tobacco leaves), the primary problem is how to automatically load the bundled large-leaf crops, place the baked semi-dry large leaves on the detection equipment and realize single-piece separation. If this cannot be achieved, automatic grading is out of the question. To achieve automatic feeding and separation, the control points of the tobacco leaves must first be identified, because ...

AI Technical Summary

Problems solved by technology

Although manual single-separation can achieve the effect of separating whole bundles of tobacco leaves, it is more dependent on manual labor, which does not achieve the effect of saving labor and reducing labor costs, and does not reflect the efficiency advantages of automatic detection equipment; Although this method can save part of the labor force, it is labor-intensive and requires workers to continuously load materials, and the actual separation effect is mediocre. There are cases where the conglomerated tobacco leaves cannot be separated, and the distance between the tobacco leaves is also uncontrollable, which is not conducive to subsequent detection.

[0004] At the same time, the main method currently used is manual grading, but worker grading depends on personal long-term operating experience, and the tobacco leaf grade standards are complex and fuzzy, and it is difficult to master them proficiently. Ordinary workers need long-term training to become skilled workers. , so the speed of manual grading and selection is slow, the accuracy rate is low, and the leaf consistency is very poor

Therefore, automatic machine selection gradually replaces manual selection, but to achieve automatic machine grading, an important prerequisite is to achieve tobacco leaf feeding, high-speed separation, unfolding, and transmission. In the state of being separated into single pieces, it is very difficult to divide the bundled tobacco leaves into single pieces and maintain a certain distance and height due to the unevenness and adhesion when the tobacco leaves are bundled, and the individual differences between the tobacco leaves are also great. thing
