Stem crutch removing system

Abstract

The invention provides a stem crutch removing system. The stem crutch removing system comprises a screening machine and a visual removing system; the visual removing system comprises a visual removingunit; the visual removing unit comprises a material dispersing mechanism, a material guiding mechanism, a visual identification and removing mechanism, a stem crutch outlet and a tobacco stem outlet;to-be-sorted materials sorted by the screening machine are fed into the material dispersing mechanism; the material guiding mechanism is obliquely arranged below an outlet of the material dispersingmechanism; the visual identification and removing mechanism is arranged close to an outlet of the material guiding mechanism; the visual identification and removing mechanism is used for removing stemcrutches in the to-be-sorted materials; the removed stem crutches are output from the stem crutch outlet; and other materials are output from the tobacco stem outlet. Compared with the prior art, thesystem has the advantages that multiple times of sorting of stem crutches and tobacco stems can be achieved through multiple methods, the stem crutch removing efficiency and technological indexes areimproved, and mistaken tobacco stem removing can be effectively avoided.

Description

technical field [0001] The invention belongs to the technical field of shredded stem recycling, and more specifically relates to a system for removing stems and canes. Background technique [0002] The stalk is a component of the tobacco stem, and the stalk in the tobacco stem accounts for about (5-15)% of the weight of the tobacco stem. Stems have high lignin content and are easy to absorb water. During the processing of cut stems, it is easy to have adverse effects on the processes of pressing stems, shredding, and feeding, resulting in unstable operation of equipment, and fluctuations in the quality of cut stems will affect the quality of cigarettes. [0003] The traditional processing method is to remove the stalks from the tobacco stems through a vibrating stalk removal machine and a drum-type stalk removal machine. Due to the large difference in diameter and shape of the stalks, the stalk screening equipment is easy to jam, and the mechanical method The removal effici...

AI Technical Summary

Problems solved by technology

There are many problems in this solution: (1) The vibrating conveyor cannot remove the materials. Since the tobacco stems contain some broken stems that need to be removed, this application cannot remove some useless broken stems in advance, which increases the effect of rear-end visual removal and efficiency

(2) Those skilled in the art usually use a high-speed belt conveyor to transport tobacco leaves. Because the area of ​​the tobacco stem is small, the friction with the belt of the high-speed belt conveyor is small, and it is easy to slip on the high-speed belt conveyor, and the moving path of the tobacco stem is unstable.

(3) In this application, the image acquisition device and the rejection valve are arranged on the parabolic path of the tobacco stem. As we all know, the parabolic paths of stems with different weights and volumes are different, and some stems reach the image acquisition device before the rejection valve. It has fallen before, resulting in the failure of culling

(4) The high-speed belt conveyor is difficult to maintain, and there is a problem of deviation, which makes the conveying path of the cane inaccurate and unstable. That is to say, the pre-placed image acquisition device and the reject valve are not on the conveying path of the cane From identification to removal, it is easy to mistakenly remove or not remove

This will obviously lead to the failure of rejection. It is necessary to constantly adjust the high-speed belt conveyor to correct the conveying path of the tobacco stems. The usability is poor and it cannot be applied in the industry.

(5) The cost of using and maintaining the high-speed belt conveyor is relatively high
