Needle drum of cigarette making machine suitable for adhesion of long filter tip and tipping paper

Abstract

The invention discloses a needle drum of a cigarette making machine suitable for adhesion of a long filter tip and tipping paper. The diameter of a drum body is 216mm; two cigarette adsorption areas with widths of 72.5mm are formed in the surface of the drum body, and the distance between the two cigarette adsorption areas is 9mm; needle strip grooves and cigarette-loading grooves are formed around the surface of the drum body at intervals; an included angle between each needle strip groove and each cigarette-loading groove is 10 degrees; an included angle between two adjacent needle strip grooves or cigarette-loading grooves is 20 degrees; one filter tip adsorption hole and three cigarette strip adsorption holes with the diameters of 4mm are sequentially formed in the cigarette-loading groove from a separation region to the outside, and distances from the filter tip adsorption hole to the three cigarette strip adsorption holes are 18mm, 30mm and 48mm in sequence; each needle strip groove has the upper width of 25mm, the lower width of 18mm and the depth of 10mm; the cigarette-loading grooves are semicircular and are 7.8mm in diameter; and the ridge width between the needle strip groove and the cigarette-loading groove is 3mm. By using the needle drum, the reliable adsorption of a cigarette strip and a filter tip and the stable conveying of the tipping paper are guaranteed, the tipping paper, the cigarette strip and the filter tip are accurately jointed and adhered, the product quality is guaranteed, the gum deposit of the needle drum is avoided at the same time, and the labor intensity of cleaning the needle drum is alleviated.

Description

technical field [0001] The invention belongs to the technical field of tobacco processing equipment, and in particular relates to a cigarette machine needle drum suitable for long filter tip sticking tipping paper, which is suitable for long filter tip production, prevents glue from sticking to the needle drum, and stably transports tipping paper. Background technique [0002] In order to adapt to the demand for cigarettes in the social environment, effectively reduce the tar content of cigarettes, and also to reduce production costs and save raw and auxiliary materials, many high-end cigarette brands are gradually changing their cigarette structure, such as (soft gift impression) Yunyan, Dazhongjiu, The length of the cigarette is shortened from 64mm to 54mm, and the length of the filter tip is extended from 20mm to 30mm. In order to meet the production requirements, each component of the cigarette making machine needs adaptive transformation. The needle drum is an importan...

AI Technical Summary

Problems solved by technology

However, the rotation speed of the needle drum reaches 7000 pieces / min. Over time, there will still be a large amount of residual glue accumulated on the needle drum, and there will be quality problems such as unstable filter tips, resulting in uneven and warped bonding of the tipping paper. edge, and even cause quality defects such as tipping paper rubbing wrinkles, air leakage, etc.
