Screening device based on tobacco shred length control of thin cigarette

Abstract

The invention relates to a screening device based on tobacco shred length control of a thin cigarette. The screening device comprises a power source, a transmission mechanism and a plurality of movable rollers, wherein the plurality of movable rollers are driven by and rotates synchronously with the power source and the transmission mechanism and are arranged at equal intervals; picking tools arearranged on the movable rollers at equal intervals along the axial directions of the movable rollers; each picking tool comprises a plurality of blades for shifting tobacco shreds and a fixed disc fixed on the corresponding movable roller; the positions of the picking tools on the adjacent movable rollers are staggered; the blades of the picking tool on each movable roller extend to a gap formed by two adjacent blades of the adjacent movable rollers so as to form staggered structure with the blades on the adjacent movable rollers; and the two ends of the blades are spaced from the adjacent movable rollers at an equal interval. According to the screening device, the tobacco shreds are selectively screened in the conveying process, and the long tobacco shreds in the tobacco shreds are flexibly and selectively screened out to be prepared for cutting, so that the uniformity of a tobacco shred structure of the thin cigarette is improved, the applicability of the tobacco shreds of the thin cigarette is improved as well, and the comprehensive quality of rolling the thin cigarette is improved further.

Description

technical field [0001] The invention belongs to the technical field of tobacco processing, and in particular relates to a screening device based on the length control of slim tobacco shreds. Background technique [0002] Slim cigarettes generally refer to cigarettes with a cigarette circumference design standard value of (17.0±1.0) mm. Compared with conventional cigarettes, the properties of slim cigarettes have changed greatly. In recent years, the production and sales of slim cigarettes in my country have increased significantly year after year, and slim cigarette-based products have become a new driving force for the development of the tobacco industry. The equipment and technology of slim cigarettes in the industry is mainly aimed at improving the packaging equipment. At present, in the processing of slim cigarettes in the tobacco industry, there are large fluctuations in the single weight of cigarettes and draw resistance, uneven distribution of cigarette densities, and...
