S1, cigarettes fall from a cigarette outlet of a cigarette warehouse, tobacco shred ends of the cigarettes fall into arc-shaped grooves 1031 on a positioning plate 103, a crank-link mechanism of a packing machine drives a cigarette pushing plate 300 to move to one side of a cigarette turret 200 through a pushing frame, and the end part of a cigarette pushing rod 301 contacts with a cigarette filter tip end and drives the cigarettes to be pushed forward into a cigarette supporting groove 201 of the cigarette turret 200;
S2, after pushing a group of cigarettes, the pushing frame moves backwards to drive the cigarette pushing plate 300 to retract, in the process, the induction magnetic ring 3035 drives the rotating shaft 3033 and the rotating plate 3032 to rotate through changing magnetic poles, so that a notch on the fixed plate 3031 is opened, a high-pressure air source enters the air collection cavity 3021 through the air inlet regulating valve 303 to balance and stabilize pressure and then is blown out through the air blowing hole 302, and the cigarette pushing channel on the bottom plate 100 of the cigarette warehouse is cleaned by blowing;
s3, after the cigarette pushing plate 300 is retracted to be separated from the outlet of the cigarette warehouse, cigarettes in the cigarette warehouse fall onto the positioning plate 103 again, the cigarette pushing plate 300 pushes the cigarettes into the cigarette supporting groove 201, at this time, the rotary plate 3032 in the air inlet regulating valve 303 rotates again under the action of the driving shaft 3033 of the induction magnetic ring 3035 to block the notch on the fixing plate 3031, thereby isolating the high-pressure air source and stopping blowing.
According to the method for protecting the quality of cigarettes by the cigarette pushing channel, the steps S1-S3 are repeated continuously under the drive of the packaging machine power equipment, cigarettes in a cigarette warehouse are pushed into the cigarette turret 200, each group of cigarettes are kept in a two-layer arrangement structure of 10-10' by the positioning of the arc-shaped grooves 1031 on the positioning plate 103 and the limitation of the protruding blocks on the inner sides of the guide blocks 104, deformation, contact and the like of the cigarettes in the pushing process of the pushing plate are avoided, the pushing channel is blown and cleaned by high-pressure gas in the retracting process of the pushing plate 300 through the arrangement of the blowing component, the switch of the air inlet regulating valve 303 is controlled to be synchronous with the action of the pushing plate 300 through the packaging machine main control system, the effect of an air inlet source on the pushing of the cigarettes in pushing is prevented, energy is saved, the efficiency of transferring and the quality of the cigarettes is effectively ensured.
It should be noted that, the specific model specification of the induction magnetic ring 3035 needs to be determined by selecting a model according to the actual specification of the device, etc., and the specific model selection calculation method adopts the prior art in the field, so the detailed description is omitted.
It should be noted that, the power supply of the inductive magnetic loop 3035 and the principle thereof will be apparent to those skilled in the art, and will not be described in detail herein.
The above description is only of the preferred embodiments of the present invention and is not intended to limit the present invention, and various modifications and variations may be made to the present invention by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
