Binary compound filter rod for tobacco as well as processing method and equipment thereof

Abstract

The invention discloses a binary compound filter rod for tobacco as well as a processing method and processing equipment thereof. The filter rod comprises an acetate fiber and active carbon hollow filter rod binary compound unit, an outer wrapping layer and an inner wrapping layer, wherein the acetate fiber and active carbon hollow filter rod binary compound unit is a cylindrical body comprising an acetate fiber filter rod section and an active carbon hollow filter rod section which are connected; the inner wrapping layer is used for wrapping the acetate fiber filter rod section; and the outer wrapping layer is used for wrapping the inner wrapping layer and the active carbon hollow filter rod section. The filter rod is cut, and a tow filter rod, tipping paper, tobacco shred and cigarette paper are cooperatively used, so that a complete cigarette can be obtained. The binary compound filter rod is unique in production process and novel in style, can greatly reduce harmful ingredients in cigarette smoke, and is provided with a better anti-counterfeiting function at the same time.

Description

technical field [0001] The invention belongs to the technical field of processing and preparing filter rods for cigarettes. Specifically, the invention relates to a binary composite filter rod made of cellulose acetate filter rods and activated carbon hollow filter rods. At the same time, the invention also designs the filter rod Processing methods and processing equipment. Background technique [0002] In the prior art, cigarette filter rods are usually made of cellulose acetate, which cannot effectively trap harmful substances in smoke. With the development of technology, a small amount of activated carbon particles have been added to the cellulose acetate filter rod to achieve the effect of intercepting harmful substances in the flue gas, but there are also the following defects: ① The activated carbon particles in the filter rod are loosely mixed in the acetate fiber There is no contact between the tow and activated carbon particles, and due to the limited capacity of t...
