Multi-level thinning screen separation device for caboes

Abstract

The invention discloses a multi-level thinning screen separation device for caboes, which comprises a screen separation driving device, a feed opening, a crushed cabo outlet and sieves, wherein the screen separation driving device drives the sieves; the sieves include a bar grate-shaped sieve, a square-mesh sieve, an elliptical slot hole sieve and a round hole sieve from high to low sequentially; each sieve comprises a baffle, a screen mesh and an oversize outlet; the feed opening corresponds to the screen mesh of the bar grate-shaped sieve; and the screen mesh of the bar grate-shaped sieve also corresponds to the that of the square-mesh sieve; the screen mesh of the square-mesh sieve corresponds to a crushed cabo collecting tank; the oversize outlet of the square-mesh sieve corresponds to the screen mesh of the elliptical slot hole sieve; the screen mesh of the elliptical slot hole sieve corresponds to that of the round hole sieve; and the screen mesh of the round hole sieve also corresponds to the crushed cabo collecting tank. According to the invention, the different sieves at different layers are used for effectively separating cabo heads, overlong stems, long stems, short stems, crushed stems and smashed pieces of the stemmed caboes subjected to threshing and redrying, and accordingly, the cabo specification is uniform, which can more meet the requirements of tobacco primary process procedures, and facilitate classification packaging, storage and transportation of the caboes.

Description

technical field [0001] The invention belongs to the technical field of tobacco processing equipment, and in particular relates to a tobacco stem multi-stage thinning and screening device capable of separating different shapes of tobacco stem materials such as stem heads, broken stems, long and short stems, and stem foam. Background technique [0002] Compared with tobacco leaves, tobacco stems have lower tar content, their physical structure is similar to that of tobacco leaves, and they have strong fire-holding ability and low cost. In traditional tobacco production, tobacco stems are usually treated as waste. In order to adapt to the development trend of "harm reduction and tar reduction", tobacco stem raw materials are usually added in current cigarette production. For this reason, how to deal with tobacco stems, making it more adaptable to tobacco production has become a research hotspot in the tobacco industry. Domestic rebaking enterprises usually only have a specifi...

AI Technical Summary

Problems solved by technology

Domestic rebaking enterprises usually only have a specification parameter of 20mm for tobacco stem processing, that is, long tobacco stems > 20mm are long. The existing tobacco stem screening equipment is based on this design, and only two layers of screens are used to screen the length Stems, broken stems, and broken foam. On the one hand, the size of the sieve is simple and single. Without further refining the screening specifications of tobacco stems, it is impossible to effectively remove stem heads, excessively long stems and other materials that are not conducive to the subsequent processing of tobacco stems, which will affect the quality of tobacco after screening. The uniformity of stems; on the other hand, the shredding equipment used by domestic cigarette companies is from abroad, and they are all designed on the basis of inches. The current screens for tobacco stems are not screened with inches as the standard. At the same time, because the current short stem screen uses a metal woven square screen, some short stems will directly fall into the broken stem groove, resulting in poor purity of the packaged tobacco stems, so that the packaged tobacco stems cannot be well cleaned after screening. Adapt to the subsequent production of cut stems
