A method for cutting cigarette filter rods

Abstract

The invention provides a method for slitting a cigarette filter stick. The method comprises the following steps: fixedly mounting a cutting blade in a blade fixed bracket; adopting a motor to drive the blade fixed bracket and a linear propeller; placing a sample to be cut on a V-shaped positioning groove in the feed end of a cutting blade plate; pushing one end surface of the sample to be cut in accordance with a distance set by the linear propeller; sending the other end surface of the sample to be cut toward the cutting blade plate along the V-shaped positioning groove; and performing the slitting of the cigarette filter stick. By the adoption of the method, the cigarette filter stick can be accurately and effectively slit, the service life of the cutting blade is prolonged, and technical effects such as convenience and fastness in cutting, and an orderly cutting section are achieved.

Description

technical field [0001] The invention relates to a cutting method, in particular to a method for cutting cigarette filter rods. Background technique [0002] In the field of tobacco technology research and production quality control, it is usually necessary to accurately cut the produced cigarette filter rods into small sections according to the specified length (or position). There are two main purposes: first, to study cigarette filter rods Filtration efficiency and characteristics of cigarette smoke at a specific segment length; second, to study the forming process quality of the section at the specific position, such as the forming quality of grooved filter rods and composite filter rods. [0003] Application No. 201020664162.2, the technical solution disclosed in the utility model patent document named "Double-Blade Filter Rod Cutter" adopts two rotating circular blades, and cuts out samples with a length of 0-3cm by changing the distance between the two blades way of r...

AI Technical Summary

Problems solved by technology

[0004] It has been proved by experiments that the technical realization of rotary cutter slitting has the following defects: defect 1, the blade wears quickly, the blade edge becomes blunt quickly, and the quality of the incision cannot be guaranteed. If a sharpening device for a small blade is installed, the mechanism will Complicated, and grinding the knife surface will produce metal dust to pollute the sample; defect 2, the high-speed rotary cutting of the blade will cause dust contamination of the sample; defect 3, when the rotary cutter cuts the filter rod without forming paper, the fibers on the edge of the section will be scattered, resulting in irregular cut sections
