Sealed conveying device and flexible cut tobacco conveying device and method of feeding system of cigarette making machine

Abstract

The invention relates to a sealed conveying device and a flexible cut tobacco conveying device and method of a feeding system of a cigarette making machine. The sealed conveying device comprises a shell, a scraping blade shaft (27) and a plurality of scraping blades (22), wherein the shell is provided with an inlet (24) and an outlet (25); the plurality of scraping blades (22) are distributed at the periphery of the scraping blade shaft (27) at intervals and the end parts of the scraping blades (22) can be in contact with an inner wall of the shell; the inner wall of the shell is wrapped to form a cylinder; and the scraping blade shaft (27) and the cylinder are concentrically arranged and the plurality of scraping blades (22) are driven to rotate, so that materials falling from the inlet (24) are led out from the outlet (25) in a sealed manner. According to the sealed conveying device provided by the invention, the scraping blade shaft rotates to drive the plurality of scraping blades to rotate, and the materials falling from the inlet of the shell are led out from the outlet of the shell, so that a sealed conveying function of the materials is realized and the airtight requirements in a transmission channel are met.

Description

technical field [0001] The invention relates to the technical field of tobacco processing, in particular to the field of tobacco feeding, and in particular to a sealed conveying device, a flexible wire feeding device and a method for a cigarette machine feeding system. Background technique [0002] figure 1 A structural schematic diagram of the flexible wire feeding device of the cigarette machine feeding system in the prior art is given, and its working process will be described below. The processed shredded tobacco is transported into the shredded tobacco hopper 1 by wind force from the wire feeder. When the air lock gate 2 is opened, the shredded tobacco falls into the pre-distribution box 3, and the metering roller 5 transports the evenly unloosed shredded tobacco to the silk storage tank 10, and the combing roller 4 combs the shredded tobacco coming out from the metering roller 5 . The steep-angle conveyor belt 9 evenly takes out the shredded tobacco from the shredded...

Problems solved by technology

[0004] (1) When the steep-angle conveyor belt 9 takes out the cut tobacco and sends it into the screening channel 8, the air flow of the screening leaks at the leveling roller 6, resulting in unstable air flow, and a large amount of cut tobacco exists in the stem;

[0005] (2) Above the screening channel, when the shredded tobacco flow is sent into the stacking chute 12, the sieving air flow is unstable here, which often cause
