Abstract

The cigarette filter with the transverse pressing groove is composed of a filter tow, a piece of forming paper and tipping paper, wherein the piece of forming paper is high-permeability paper, the filter tow is wrapped into a cylindrical shape by the piece of forming paper, the tipping paper is wrapped outside the piece of forming paper, the tipping paper is punched with air holes, the rear end of a cigarette is connected to the front end of the tipping paper, the circumferential surface of the piece of forming paper is pressed with the circumferential transverse pressing groove, and the transverse pressing groove is annular, polygonal or spiral. Because the transverse pressing groove inwards compresses the forming paper and the filter tows to form a transverse tow dense surface, when smoking, smoke enters the extrusion dense surface from an area where the tows are evenly loosened and then enters an area where the tows are evenly loosened, in unit length, the contact tightness between the smoke and the tows is increased, the contact path is increased, the contact time is increased, harmful ingredients in the smoke are more fully filtered, and the filtering efficiency is increased.

Description

Cigarette filter tip with transverse pressing groove

Technical Field

The technology belongs to the technical field of cigarette filters, and relates to a cigarette filter with a transverse pressing groove.

Background

In the prior art, a plurality of technologies are adopted on the cigarette filter tip, a plurality of composite filter tips which divide the filter tip into multi-stage combinations are provided, a rod-in-rod filter tip which is a thin rod is installed in a filter tip rod, a corrugated filter tip which is a layer of corrugated paper is installed between formed paper and a tow, the cigarette filter tips with different designs are provided, the filtering principles and modes are different, the purpose is to increase the filtering effect on harmful ingredients such as nicotine and tar in smoke and reduce the harmful ingredients in smoke of smokers, but in practical application, the various cigarette filter tips have common defects, namely the product structure is complex, the production process and equipment of the filter tip are changed greatly, the production cost is high, and the filtering effect efficiency is not high.

Disclosure of Invention

The utility model aims at providing a take cigarette filter of horizontal indent solves among the prior art cigarette filter structure complicacy, high in production cost, the not good problem of filter effect.

The technical scheme of the utility model is that: a cigarette filter with a transverse pressing groove comprises a filter tow, a piece of forming paper and tipping paper, wherein the piece of forming paper is high-permeability paper, the filter tow is wrapped into a cylindrical shape by the piece of forming paper, the tipping paper is wrapped outside the piece of forming paper, the tipping paper is punched with air holes, the rear end of a cigarette is connected with the front end of the tipping paper, and the circumferential surface of the piece of forming paper is pressed with the circumferential transverse pressing groove.

The transverse pressing groove is annular, polygonal or spiral.

At least one annular or polygonal transverse pressing groove is formed on the circumferential surface of the forming paper.

The annular shape on the plug wrap is the ring surface of the polygonal transverse pressing groove or the plane of the polygon is inclined to the axial direction of the cigarette filter.

By adopting the technical scheme, as the transverse press grooves are pressed on the circumferential surface of the cigarette filter forming paper, the transverse press grooves press the filter tows inwards to form a transverse tow dense surface, so that an originally uniform smoke filtering channel inside the tows is deformed into a channel with alternate density, when smoking, smoke flows through the cigarette filter, the smoke enters an extrusion dense area from a uniform loose area of the tows and then enters the uniform loose area, and passes through transverse movement of inward contraction and dense and outward expansion and diffusion, the flow of the smoke in the filter tows is changed from original linear movement into curvilinear movement, the contact tightness between the smoke and the tows is increased, the contact path is increased, the contact time is increased, and the amount of harmful components such as nicotine, tar and the like in the smoke adhered to the tows is increased, harmful components are more sufficiently filtered, and the filtering efficiency is increased.

In addition, in the prior art, in order to reduce the content of harmful components such as nicotine and tar in smoke, the forming paper of the cigarette filter tip adopts high-permeability paper, and air holes are punched on tipping paper on the outer layer of the filter tip, so that air can enter from the air holes of the tipping paper during smoking, and enters into a tow after passing through the forming paper to be mixed with the smoke so as to dilute the smoke and reduce the concentration of the smoke, thereby reducing the content of harmful components such as nicotine and tar in the smoke in unit volume. After the technical scheme is adopted, because the movement resistance of the smoke at the transverse indent is increased, under the action of atmospheric pressure, air enters the indent gap on the outer circumference of the plug wrap paper from the tipping paper near the transverse indent, and then the air inflow at the loose side of the tow at the rear end of the indent through the plug wrap paper from the indent gap is increased, so that the air amount entering the filter tip is increased.

By adopting the technology, the filtering effect can be improved through the transverse press groove, so that in actual production, the depth, the width and the shape of the press groove can be adjusted, the use density of the filter tows is reduced, or the length of the filter tip is shortened, the tows are reduced on the premise of meeting the quality requirement of the cigarette filter tip, and the purpose of saving the production raw material is achieved.

In the implementation process of the technical scheme, transverse press grooves can be pressed on a cigarette filter product in multiple modes, wherein one simple mode is to add a transverse creasing machine and press the transverse press grooves on the forming paper and the tows of the filter rod in a die pressing or extruding mode. After entering a cigarette packaging machine, the raw material filter rod with the pressing groove is wrapped by tipping paper and connected with cigarettes, and then the filter tip cigarette product with the same appearance as the existing product and smooth appearance can be produced.
