Variable volume metering tube applied to blending of shredded tobacco

Abstract

The invention discloses a capacity-variable metering tube used in tobacco shred blending. The capacity-variable metering tube comprises a pipe body, a feeding funnel, a discharge roller, a first drive mechanism, a limit sliding plate and a second drive mechanism, wherein the upper end of the front side wall of the pipe body is hinged to form a movable plate, and the first drive mechanism is arranged on a first drive mechanism mounting support and used for driving the movable plate to rotate around a hinge shaft; the limit sliding plate is arranged on the front of the lower part of the movable plate by virtue of at least two bolts, the limit sliding plate is slidably connected with the movable plate, and the discharge roller is arranged under the limit sliding plate; when the second drive mechanism drives the limit sliding plate and the discharge roller to move up and down so as to arrive at the highest position together, and the lower end of the movable plate is still higher than the discharge roller. The capacity-variable metering tube is capable of improving the control accuracy of a cigarette blending process, ensuring the uniformity of blended materials, meeting the requirement for wide blending proportion range of 3%-60% and ensuring the blending precision, the blending uniformity and the production continuity.

Description

technical field [0001] The present invention relates to the technical field of tobacco processing equipment, in particular to a tobacco shredded process in which various tobacco material components (stems, expanded shredded tobacco, reconstituted shredded tobacco and recycled shredded tobacco, etc.) are mixed accurately and evenly according to product formula design requirements. Metering tube for use in dry shredded leaves. Background technique [0002] The metering tube is used in the tobacco industry's silk production line, which is a device used to control material output and metering. The material flows out to the electronic belt scale according to the section defined by the metering tube, and the balanced control of the material is realized by controlling the section area. The metering tube is mainly composed of three parts: the tube body, the upper hopper and the discharge roller. The upper hopper is located directly above the tube body. The material enters the tube ...

AI Technical Summary

Problems solved by technology

There are also tobacco companies redesigning and transforming the metering tube so that the volume of the metering tube can be adjusted to meet the needs of large and small ratios of blended materials, and to ensure the uniformity of blended materials and the continuity of production of the variable capacity device, but there are deficiencies in that Some blending devices need to manually adjust and change the volume of the metering photocell and the height of the material limit level according to the ratio of the material blending before production; Due to the need for separate warehouse control inside the multi-cavity material metering tube, the design is complicated and the control is cumbersome.
