In recent years, whether in coarse, medium or fine cigarette, the use of composite filter rods has become increasingly popular.
The composite filter stick is a functional filter stick which can be freely matched, and is an indispensable new platform for expanding the application of new materials. The general composite filter stick is characterized in that two to three basic material sticks are firstly cut into short filter stick segments according to preset length, then the segments are sequentially arranged and combined according to the requirement through a special conveying device, then the segments are wrapped into a filter stick strip through a forming paper of a cigarette gun, and finally the steps of cutting, stick forming, packaging and the like of the filter stick strip are completed. The prior composite filter stick forming machine technology can produce composite filter sticks with various circumferential specifications, and the production speed can reach more than 400m/min at most.

8. A negative pressure conveying process for material rod segments of composite filter rods is characterized in that: use of a slug segment negative pressure delivery apparatus according to any one of claims 1 to 7, the slug segment negative pressure delivery process including the steps of:
s1, at the material rod section output unit (10), the negative pressure conveying belt (30) captures the material rod sections (62) output by the material rod section output unit (10), and the material rod sections (62) are kept on the negative pressure conveying belt (30) under the action of negative pressure at a negative pressure adsorption hole (31);
s2, the negative-pressure conveying belt (30) conveys the material rod segments (62) to a negative-pressure steering conveying disc (40);
at the joint of the negative-pressure conveying belt (30) and the negative-pressure steering conveying disc (40), the negative-pressure adsorption holes (31) of the negative-pressure conveying belt (30) release adsorption on the material rod segments (62), and the material rod segments (62) are captured by the negative-pressure adsorption arm claws (42) of the negative-pressure steering conveying disc (40);
s3, the negative pressure steering conveying disc (40) conveys the material rod segments (62) to a material rod segment receiving unit (20) of the cigarette gun;
at the joint of the negative pressure steering conveying disc (40) and the material rod segment receiving unit (20) of the cigarette gun, the negative pressure adsorption arm claw (42) of the negative pressure steering conveying disc (40) releases adsorption of the material rod segment (62), and the material rod segment (62) is captured by the material rod segment receiving unit (20) of the cigarette gun.
