Description
Technical Field
[0001] The utility model relates to the technical field of cigarette tipping paper, in particular to a flame retardant cigarette tipping paper. Background Art
[0002] Cigarette tipping paper is a special paper used by cigarette factories to connect filters to cigarette sticks. It plays a role in connecting and fixing during the cigarette packaging process.
[0003] Usually, this kind of paper is also called tipping paper. The main function of tipping paper is to firmly bond the filter and cigarette together to ensure the integrity and stability of cigarettes during transportation and sales. The production of tipping paper usually adopts gravure printing process. The paper used is ordinary tipping paper white base paper, and the ink is gravure printing alcohol ink.
[0004] However, the kraft paper used in cigarette tipping paper is flammable. If a smoker stops smoking due to some circumstances after lighting a cigarette, but the cigarette butt is still burning, most smokers may rotate an object that can clamp and fix the cigarette butt to place it. At this time, the tobacco position of the cigarette butt will be burned out over time, leaving only the filter sponge position. However, the filter sponge is similar to the kraft paper and will be ignited by the high temperature of the cigarette butt. The object that clamps and fixes the cigarette butt may fall off due to the burning of the clamping position of the cigarette butt, which may cause the high temperature of the cigarette butt to ignite surrounding flammable materials and cause a fire. In view of this, a flame-retardant cigarette tipping paper is provided to overcome the above-mentioned defects. Utility Model Content

[0023] As a further implementation scheme of the above technical scheme: the number of tipping paper body 1 and filter sponge 2 are both at both ends, and the port positions of the tipping paper body 1 and the filter sponge 2 are set at the overall front quarter position, which can be used to block the burning position and reduce the danger of the filter sponge 2 and the tipping paper body 1 after burning to a certain extent.
[0024] As a further implementation scheme of the above technical scheme: the width and opening position of the groove 7 opened on the outside of the filter sponge 2 are the same as the width and setting position of the wood pulp fiber paper 3, and the number of the grooves 7 opened on the outside of the filter sponge 2 is the same as the number of the wood pulp fiber paper 3, which is two, making it convenient for the operator to assemble the two sections of the filter sponge 2 and not easy to fall off.
[0025] As a further implementation scheme of the above technical scheme: the cross-sectional diameter of the barrier plate 6 is the same as the cross-sectional diameter of the top ends of the two sections of filter sponges 2, and the barrier plate 6 and the filter sponges 2 are fixed by means of a viscose connection between the inner side of the polyester fiber layer 5 and the filter sponges 2, and the viscose on the outer surface of the filter sponge 2 is adhered to the polyester fiber layer 5, which can prevent the outer side of the barrier plate 6 and the top ends of the filter sponges 2 from affecting the penetration of smoke by viscose adhesion.

The wood pulp fiber paper 3 also has a certain flame retardant effect, and the wood pulp fiber paper 3 separates the tipping paper body 1. When the tipping paper body 1 burns to the wood pulp fiber paper 3, it automatically stops burning to the rear of the tipping paper body 1.
[0028] Working principle:
[0029] When using the utility model, the grooves 7 opened on the surfaces of the two sections of the filter sponges 2 are put on the inner sides of the wood pulp fiber papers 3 at the front and rear ends of the polyethylene layer 4, the top ends of the filter sponges 2 are in contact with the baffle plate 6 located on the inner side of the polyester fiber layer 5, and then the inner surface of the filter sponges 2 is in contact with and adhered to the adhesive applied on the inner side of the polyester fiber layer 5, and then the tipping paper body 1 is wrapped around the outer side of the fixed filter sponges 2, and the filter tip of the cigarette is assembled after wrapping and fixing. When the cigarette starts to burn to the front top of the filter sponges 2, the filter sponges 2 will continue to burn with the tipping paper body 1, and when the filter sponges 2 and the tipping paper body 1 burn to the edge of the wood pulp fiber paper 3, the tipping paper body 1 stops burning due to the flame retardant effect of the wood pulp fiber paper 3, while the filter sponges 2 continue to burn. When the filter sponge 2 burns the baffle plate 6 on the inner side of the polyester fiber layer 5, the flame is directly blocked by the baffle plate 6 to prevent the flame from continuing to burn the filter sponge 2 at the end. At this time, the flames of the tipping paper body 1 and the filter sponge 2 are both flame-retardant and extinguished, and a high-temperature resistant base paper 9 and a carbon paper 10 are arranged behind the tipping paper body 1 and the filter sponge 2, and a hardening coating 8 is applied to the outer side of the base paper 9. When the smoker smokes a cigarette, the filter sponge 2 and the tipping paper body 1 at the tail will not be softened by heat, causing the filter sponge 2 and the tipping paper body 1 to become soft and flat, affecting the smoking situation. At the same time, when the cigarette butt is extinguished, the hardened base paper 9 and carbon paper 10 will also play a certain supporting role to prevent the filter sponge 2 and the tipping paper body 1 from becoming soft and pressing the cigarette butt downward to cause the whole to bend.
