Description

Cigarette tight head deviation reduction disk is prevented to PROTOS series cigarette machine

Technical Field

The utility model belongs to the technical field of cigarette making machine equipment, and particularly relates to a cigarette tight head deviation prevention reduction disc of a PROTOS series cigarette making machine.

Background

In the cigarette production, the leveling device is an important component for controlling the quality of the cigarette products, and mainly comprises a transmission gear, a transmission shaft, a tobacco brushing wheel and two reducing discs, wherein redundant tobacco shreds in tobacco rods are removed through the rotation of the two reducing discs and the tobacco brushing wheel, so that the tobacco shred quantity fed into a tobacco pipe accords with the standard weight of the tobacco rods, and the redundant tobacco shreds are fed back to a storage area of a tobacco shred feeding device through a main tobacco shred returning conveyor belt, an auxiliary tobacco shred returning conveyor belt and a tobacco shred dropping vibration groove.

The grooves on the cutting disc can enable the corresponding areas on the tobacco sucking belt in the tobacco sucking guide rail to retain more tobacco shreds, so that the generated tobacco shreds have denser tobacco shreds at the end part of the length of the cigarette, a tight head position is formed, and the position is synchronous with the cutter, so that the end part of the cut cigarette is full and not loose. At present, most of the cutting discs used on cigarette making machines are semicircular groove cutting discs, and the cutting discs can form two tight head positions at the end part of a cigarette and the filter tip attaching end, so that the cutting discs have better effects of reducing the generation of empty cigarettes and improving the rubbing quality.

However, the tobacco shreds are conveyed on the tobacco sucking guide rail and the tobacco gun for a long distance through the cut-down disc rotating at a high speed and the cut-down bundle of the brush wire wheel in a matched manner, so that the phenomenon of sliding of the tobacco bundles in a tight section occurs, the cutting position of the cutter cannot be guaranteed to be the tightest position of the tobacco bundles, the problem that one ends of two tobacco rod ends generated by cutting are tighter and the other ends of the two tobacco rod ends are looser is caused, and after the tobacco rods are conveyed by drums of a tipping machine, the looser tobacco rods can cause the problem of empty ends of the tobacco rod ends, the quality of the tobacco rod is seriously influenced, and meanwhile, more waste products with empty ends are generated.

Disclosure of Invention

In order to solve the problems in the prior art, the utility model provides the tray device capable of preventing the problem of empty cigarette ends caused by sliding of tobacco shreds, which can avoid the problem of empty cigarette quality caused by synchronous deviation between the cutting position of a long cutter for cutting tobacco shreds and a tight section of the tobacco shreds, which is caused by sliding of the tobacco shreds when the tobacco shreds are conveyed in a long distance between a tobacco suction guide rail and a tobacco gun.
