It will be apparent to those skilled in the art that various changes and modifications can be made in the embodiment described, and that all the obvious changes or modifications which come within the spirit and scope of the invention are deemed to be within the scope of the invention.
Throughout the specification, a portion "comprising" a component means that other components may be included, but not excluded, unless a feature opposite thereto is stated.
As shown in FIG. 1, a function tube preparation method of the present invention comprises the following steps a to c.
Step a: the paper tube is formed by rolling multiple layers of cellulose-containing material. Specifically, step a further includes: the multi-layer food grade paper and/or regenerated cellulose paper is rolled to form the outer layer of the paper tube, and the adhesive is coated between the layers of food grade paper and/or regenerated cellulose paper. The food grade paper materials comprise food grade paperboard, food grade kraft paper and food grade kraft paper. The ration of the food grade paper material is 30g/m 2 ～120g/m 2 . Here, the binder may be latex, aqueous gel, or the like.
Step b: the gel and the adhesive are uniformly sprayed on the inner wall of the outer layer of the paper tube to form an intermediate gel layer. The middle gel layer is composed of one or more materials of polyethylene glycol, latex, natural vegetable gum, paraffin and modified cellulose with different molecular weights. The intermediate gel layer is made of a material which can flow after being heated and is solid wax-like at normal temperature. Preferably, the middle gel layer comprises polyethylene glycol, paraffin wax and cellulose, wherein the polyethylene glycol accounts for 10-60%, the paraffin wax accounts for 10-35%, and the cellulose accounts for 0-5%. The step b also comprises that the material of the middle layer is heated to 50-150 ℃ before being sprayed on the inner wall of the outer layer of the paper tube. This is done to obtain better flowability of the material and to facilitate spraying.
Step c: the inner wall of the middle gel layer is uniformly sprayed with powder to form a powder particle inner layer, and the powder particles are one or more of natural plant powder, polymer powder or inorganic material powder. The natural plant powder comprises one or more of tobacco powder, tea powder, chinese herbal medicine powder, dried orange peel powder and arrowroot powder, the polymer powder comprises polymer microsphere powder, and the inorganic material powder comprises attapulgite powder and montmorillonite powder. The mesh number of the granular powder is between 60 and 200 meshes. Preferably, the particle powder has a mesh number of 60 to 100 mesh, and can be directly sprayed. In other embodiments, when the particle size is 150-200 mesh, the particles are relatively fine and not suitable for direct spraying, and the particle powder may be mixed with natural plant extracts, cellulose and the like to be granulated manually and then sprayed. Here, it is preferable that the particle powder is present in a ratio (weight percent)
10-70%, 10-20% of natural plant extract and 5-10% of cellulose. Step c also includes cooling the intermediate gel layer to a temperature of from 0 ℃ to 30 ℃ prior to spraying the powder particle inner layer.
The step b and the step c are steps of spraying the middle gel layer and the inner layer of the granular powder, and are realized by special inner core material forming pipelines (inner core pipelines for short) with special structural design. Specifically, the invention adds an intermediate layer applying device and an inner layer applying device on the basis of the existing paper tube forming machine. The inner layer applying device is provided with a central pipeline, the middle layer applying device is provided with an annular pipeline with an annular central pipeline, and the central pipeline and the annular pipeline are coaxially arranged to jointly form the inner core pipeline (namely, the special inner core pipeline replaces the forming inner core of the existing paper tube forming machine). The annular line is designed to spray gel and adhesive. The port of the annular pipeline is provided with a nozzle, and gel and adhesive are sprayed on the inner wall of the outer layer of the paper tube through the annular nozzle. The central pipeline is designed to spray powder particles, the port of the central pipeline is provided with a nozzle, and the powder particles are uniformly sprayed onto the middle gel layer through compressed air. During the application of the intermediate and inner layers, the outer layer of the paper tube is moving (e.g., the paper tube is pulled by the tape of the existing paper tube forming machine), while the central and ring-shaped tubes of the core tube are stationary. When the paper tube outer layer is moved to the tube port, the central tube nozzle and the annular tube nozzle start to work. Preferably, there is a space between the port nozzle location of the central line and the port nozzle location of the annular line. The purpose of this interval is to spray the inner layer of particulate powder again after the intermediate gel layer has been sprayed for a certain period of time until it cools but is not fully cured (semi-cured), thereby more effectively adhering the inner layer of particulate powder to the intermediate layer. Preferably, the interval may be 10mm to 100mm, and the interval distance may be adjusted according to the cooling-curing time of the gel layer.
And step c, the method further comprises a diameter control step, a shaping step and a slitting step for the functional pipe.
When the high-temperature flue gas passes through the functional pipe prepared by the method, the air flow can exchange heat with the inner layer material and the middle layer material, so that the temperature of the air flow can be reduced. And when the flue gas flows through, part of harmful components in the flue gas can be settled and intercepted by the inner layer of the particle powder, and the particle powder adsorbs part of harmful components in the flue gas, so that the content of harmful substances in the flue gas is reduced and the harmful substances enter a human body. In addition, the temperature of the middle gel layer and the inner layer of the granular powder rises in the process of absorbing the heat of the flue gas, and the aroma components contained in the middle gel layer and the inner layer of the granular powder can be released by heating, so that the effects of increasing the aroma quality and the aroma quantity are further achieved.

Specifically, in this embodiment, the food grade kraft paper 1 is glued by the gluing device, the second food grade kraft paper 3 is glued by the gluing device, so that the glue applied by the gluing device bonds the first food grade kraft paper 1 and the cellulose acetate film 2, and then the glue applied by the gluing device bonds the second food grade kraft paper 3 and the cellulose acetate film 2. Specifically, the food grade kraft paper 1 has a basis weight of 60g/m 2 The basis weight of the cellulose acetate film 2 is 50g/m 2 The ration of the food grade kraft paper 2 is 60g/m 2 . After the 3 paper tapes are primarily rolled into the outer layer of the paper tube through the inner core by the belt, the paper tube is pulled to move downstream (in the direction indicated by the arrow) by a transmission cloth belt (not shown) matched with the diameter control device 6.
And 2, spraying food-grade PEG6000, paraffin and cellulose on the inner wall of the outer layer of the paper tube from a pipeline port annular nozzle 42 through an annular pipeline 41 of the intermediate layer applying device 4 to form a PEG6000 intermediate layer with a certain thickness. Specifically, food-grade PEG6000 accounts for 60% (weight percent), paraffin accounts for 30% and cellulose accounts for 10%. The middle layer applying device 7 also has a uniform flow pump, can control the fluidity of liquid, has a temperature control function, and can meet the heating function of feed liquid at normal temperature to 300 ℃.
And 3, after the intermediate layer is formed, and when the intermediate layer material is not completely cured (semi-cured state), spraying tobacco powder particles on the inner wall of the intermediate layer from a pipeline port nozzle 52 through a central pipeline 51 of the inner layer applying device 5 to form a layer of particle powder inner layer, and adjusting the thickness of the particle powder inner layer according to the process, thereby forming the inner layer. As shown in fig. 2, the nozzle 52 is spaced from the annular nozzle 42.
And 4, after the functional tube comprising the paper tube outer layer, the middle gel layer and the particle powder inner layer is molded, carrying out diameter shaping and temperature cooling on the functional tube through a diameter control device 6, and solidifying the outer diameter of the functional tube to ensure that the outer diameter of the functional tube meets the technological requirements.
