Final cutting drum, final cigarette cutting device and cutting method of final cigarette cutting device, and assembling machine

Abstract

The invention relates to a final cutting drum, a final cigarette cutting device and a cutting method of the final cigarette cutting device, and an assembling machine. The final cutting drum comprisesa cutting drum wheel provided with a circular knife groove; the cutting drum wheel is provided with a cigarette containing tank used for receiving cigarettes, and an air absorbing hole is formed in the bottom of the cigarette containing tank. According to the final cutting drum, by arranging the air absorbing hole in the bottom of the cigarette containing tank, and the air absorbing hole can attract the cigarettes positioned in the cigarette containing tank in an air absorbing state, so that the cigarettes are effectively prevented from being misplaced due to dropping from the cigarette containing tank, the stability of the cigarettes is improved during cutting, and the cutting quality of the cigarettes is further improved.

Description

technical field [0001] The invention relates to the technical field of tobacco machinery, in particular to a final cutting drum, a cigarette final cutting device, a cutting method thereof, and a tipping machine. Background technique [0002] The final cutting device includes a combined structure of a slitting circular knife and a final cutting drum. The position of the slitting circular knife is fixed relative to the position of the final cutting drum, and is driven by a motor to complete double-length tobacco rod segments and double-length cigarette groups respectively. cutting. The final cutting device can ensure the normal production of ordinary filter stick cigarettes, and for the composite filter tip (composite filter tip: a compound produced by two or more different filter materials) that has been used in the production of cigarettes For special filter rods), it was found in the production process that the MAX1-8 splicing machine still has some shortcomings in ensurin...

AI Technical Summary

Problems solved by technology

The final cutting device can ensure the normal production of ordinary filter stick cigarettes, and for the composite filter tip (composite filter tip: a compound produced by two or more different filter materials) that has been used in the production of cigarettes For special filter rods), it was found in the production process that the MAX1-8 splicing machine still has some shortcomings in ensuring the cutting quality of composite tip rod cigarettes. Inconsistent semi-circular grooves, in which the length of the smoke receiving grooves on both sides of the circular knife groove is only 5mm, the contact area with the cigarette is small, and the rigidity of the cutting compound filter assembly position is small, as long as it is subjected to a large cutting resistance, it will be dislocated. It is easy to cause problems such as cigarette filter tip burr, wire drawing, tipping paper wrinkle, etc.
