Cut tobacco suction band guide rail device of cigarette making machine

Abstract

The invention discloses a cut tobacco suction band guide rail device of a cigarette making machine. The cut tobacco suction band guide rail device comprises multiple guide rail units, each guide rail unit comprises an inner guide rail piece and an outer guide rail piece which are arranged in a relatively parallel manner, multiple cut tobacco suction band supporting blocks are arranged between each inner guide rail piece and the corresponding outer guide rail piece, each cut tobacco suction band supporting block comprises a long-strip-shaped body, multiple supporting convex blocks which protrude downward and are positioned on a same horizontal plane are arranged at the bottom of each body, the bottom of each supporting convex block is minor-arc-shaped, the supporting convex blocks are arranged along the length direction of the corresponding bodies, multiple first through holes which are up-down through are formed in each body, each two adjacent guide rail units are connected through a connection supporting block, two first convex blocks which protrude downward are arranged at two ends of the bottom of each connection supporting block, the bottom of each first convex block is minor-arc-shaped, and the first convex blocks and the corresponding supporting convex blocks are positioned on a same horizontal plane. The cut tobacco suction band guide rail device has the advantages that the cut tobacco band supporting blocks of special structure are arranged between each inner guide rail piece and the corresponding outer guide rail piece, so that uniformity in thickness of a cut tobacco layer below a cut tobacco suction band is guaranteed.

Description

technical field [0001] The invention relates to the technical field of cigarette production and processing equipment, in particular to a ribbon suction belt guide rail device of a cigarette machine. Background technique [0002] The suction ribbon of the protos70 cigarette machine is the main part of feeding and supplying filaments in the cigarette rolling process. It mainly completes the adsorption and transmission functions of the shredded tobacco. The wheel completes the function of the turnaround of the suction ribbon to transfer the cut tobacco. The suction ribbon is made of nylon filaments woven vertically and horizontally. In order to ensure the suction air permeability and tensile wear resistance of the suction ribbon, there are also fixed requirements for the hole spacing of the suction ribbon. The working surface of the suction ribbon is the guide rail of the suction ribbon. Below the guide rail of the silk suction belt, lining plates are respectively arranged on ...

AI Technical Summary

Problems solved by technology

[0004] Existing ceramic bead formula suction ribbon guide rail has following shortcoming: one, the supporting surface of porcelain bead 7 is only the lower end edge part of porcelain bead 7 to the support surface of suction ribbon when porcelain bead 7 works, and the wider part in the middle part of porcelain bead 7 can't bring into play effective effect, instead It becomes an obstacle to reduce the air permeability of the guide rail of the suction ribbon and hinder the suction effect of the negative pressure suction; 2. The porcelain bead 7 is running at high speed while working, and its surface is easy to be stained with tobacco powder or oil or the center pin is easy to wrap the suction ribbon Nylon wire, etc. hinder the rotation of the porcelain bead 7, causing the outer working surface of the porcelain bead 7 to wear into a convex and concave irregular surface, which affects the uniformity of the thickness of the shredded tobacco layer under the suction ribbon, resulting in uneven weight and empty cigarettes; When working at high speed, the center hole of the porcelain bead 7 and the center pin shaft are easy to wear and tear, resulting in large shaking. The porcelain bead 7 jumps up and down when it rotates, which affects the uniformity of the thickness of the tobacco layer at the lower part of the suction belt, resulting in uneven weight of cigarettes and short ends.
