Cigarette filter stick packaging paper tape center line glue coating device and method

Abstract

The invention provides a cigarette filter stick packaging paper tape center line glue coating device and a method. The device comprises a glue supply mechanism, a packaging paper tape supply mechanism and a gluing mechanism, and is characterized in that the gluing mechanism comprises a first mold, a second mold and a power mechanism for driving the first mold and the second mold to synchronously swing, wherein the the working surface of the first mold is a horizontal plane, and a glue inlet groove with a glue inlet, a glue storage groove and glue outlet grooves with glue outlets are formed in the working surface; the working surface of the second mold is a horizontal plane; the first mold and the second mold are tightly connected into a whole through the opposite working surfaces, and the glue inlet groove with the glue inlet, the glue storage groove and the glue outlet grooves with the glue outlets in the first mold form glue supply channels which communicate with one another; and the first mold and the second mold which are tightly connected into a whole are connected with a power machine through a mounting mechanism, and the power machine drives the first mold and the second mold which are tightly connected into a whole to synchronously swing at a set angle. The gluing thickness is uniform, pollution to equipment is avoided, the packaging paper tape is unobstructed, and the gluing mechanism is kept clean and moist.

Description

technical field [0001] The invention relates to a device and method for coating centerline glue on filter stick wrapping paper for cigarettes, and belongs to the technical field of cigarette production. [0002] technical background [0003] In the production process of cigarette filter rods, it is necessary to glue the center line and seal of the formed wrapping paper before wrapping the filter material with the wrapping paper, and then carry out sealing and cutting to obtain filter rods of a set length . Among them, the purpose of glue on the middle line of the wrapping paper tape is to bond and fix the filter material on the wrapping paper, so as to avoid the relative slippage between the filter material and the wrapping paper caused by other external forces during the cutting or conveying process of the filter rod, resulting in unsatisfactory Qualified filter rod. [0004] When the existing filter rod forming machines apply glue to the center line of the wrapping paper ...

AI Technical Summary

Problems solved by technology

[0004] When the existing filter rod forming machine glues the center line of the wrapping paper tape, most of them use the needle-type dispensing valve to apply glue, or the non-contact atomization glue. The existing defects or deficiencies are as follows: 1) The needle-type dispensing When the valve is sprayed with glue, the glue nozzle should keep in contact with the wrapping paper tape with a speed of more than 500 m / min, which is very easy to cause wear to the nozzle. Blocking the nozzle will cause glue breakage, and the relative position between the glue spray nozzle and the wrapping tape is not easy to adjust, which will cause glue accumulation and affect the glue quality

In addition, when it comes to gluing high-transparency wrapping paper tape, because the thickness of the glue mark is inconsistent with the thickness of the middle and both sides, the glue will penetrate to the back of the wrapping paper tape and pollute the equipment

2) When glue is applied by non-contact atomization spraying, it is easy to produce filamentous dry glue due to glue splashing, which makes it difficult to adjust the thickness and uniformity of the glue, resulting in unstable adhesion, and this glue application method is affected by the viscosity of the glue. , solid content and other physical properties are greatly affected, the adaptability to glue materials is poor, and it is inconvenient to use and maintain
