Abstract

A preparation method for a multi-section aerosol generating product. The preparation method comprises the following steps: step I, preparation of a filter rod bar; step II, filling of an aerosol-generating material; and step III, formation of an aerosol-generating rod (6). The method of first compounding and then filling can greatly improve the production efficiency, can guarantee that a blocking piece (2) and a filtering piece (4) are stable and do not move during a suction or transportation process, and can better maintain the consistency of the axial length of different sample cavity sections. In addition, the flowing aerosol-generating material is filled in a squeezing-in manner and is then dried and expanded, such that the flowing aerosol-generating material is solidified to form the fixed aerosol-generating rod (6); by using the squeezing-in method, the production efficiency is higher; and the aerosol-generating rod (6), which is obtained after drying and expansion, has a pore structure, thereby facilitating the release and circulation of aerosol.

Description

一种多段式气溶胶发生制品的制备方法Preparation method of multi-stage aerosol-generating products 技术领域Technical field
本发明涉及加热不燃烧卷烟技术领域，具体涉及一种多段式气溶胶发生制品的制备方法。The invention relates to the technical field of heat-not-burn cigarettes, and in particular to a preparation method of a multi-stage aerosol-generating product.
背景技术Background technique
随着消费者对于健康问题的重视及对卷烟产品个性化体验的需求提升，烟草行业不断响应消费者的需求升级，开发出各种具有降焦减害的吸烟制品。其中，加热卷烟由于其卷烟加热方式不同于传统卷烟制品，使其能够在满足消费者对于卷烟产品的感官需求的同时提供更加健康的抽吸体验。As consumers pay more attention to health issues and demand for personalized experiences in cigarette products, the tobacco industry continues to respond to the upgrading of consumer demands and develop various smoking products that reduce scorch and harm. Among them, heated cigarettes can provide a healthier smoking experience while meeting consumers' sensory needs for cigarette products because their cigarette heating method is different from traditional cigarette products.
颗粒型加热卷烟的气溶胶生成基质为散装的气溶胶生成颗粒，现有技术中由于散装的气溶胶生成颗粒无法固定，必须用灌装的方式装入外管中，且气溶胶生成颗粒段两侧需要通过封口纸和封堵件的方式固定颗粒，而为了汇聚气溶胶和增大烟雾量，封堵件的下游通常为外管限定出的一段空腔(空腔段)，空腔段的下游为过滤段。目前制备上述气溶胶发生制品采用的是灌装的方法，生产工艺顺序为：对管材一端封口，然后从另一端依次填装气溶胶生成基质、封堵件和过滤件，在填装过滤件的时候预留出和封堵件之间的空腔距离，且封堵件和过滤件外表面与纸管内壁是没有胶粘的，直接灌装放到固定位置后通过与纸管内壁的摩擦力固定。上述灌装制备方法的问题是：1、灌装时管材垂直放置，空腔两侧封堵件和过滤件位置难定位，很容易出现不同样品空腔段轴向长度不一致的问题；2、封堵件和过滤件外表面与纸管内壁仅靠摩擦力固定，运输过程封堵件和过滤件容易向空腔段位移，或者在抽吸过程中过滤件被部分吸出外管；3、灌装的方法限制其只能针对单独管材批量灌装，生产效率低。The aerosol-generating matrix of particle-type heated cigarettes is bulk aerosol-generating particles. In the prior art, since the bulk aerosol-generating particles cannot be fixed, they must be filled into the outer tube by filling, and the aerosol-generating particle segments have two sections. On the other hand, the particles need to be fixed by means of sealing paper and plugging parts. In order to collect aerosols and increase the amount of smoke, the downstream of the plugging part is usually a cavity (cavity section) defined by the outer tube. The cavity section The downstream is the filtration section. At present, the filling method is used to prepare the above-mentioned aerosol-generating products. The production process sequence is: seal one end of the pipe, and then fill the aerosol-generating matrix, sealing member and filter member sequentially from the other end. After filling the filter member, At the same time, reserve a distance between the cavity and the sealing member, and the outer surface of the sealing member and the filter member are not glued to the inner wall of the paper tube. After direct filling and placing it in a fixed position, the friction with the inner wall of the paper tube will pass. fixed. The problems with the above filling preparation method are: 1. When filling, the pipe is placed vertically, and the positions of the sealing members and filter members on both sides of the cavity are difficult to locate. It is easy to have inconsistent axial lengths of the cavity segments of different samples; 2. The sealing The outer surface of the plugging piece and filter piece and the inner wall of the paper tube are fixed only by friction. During transportation, the plugging piece and filter piece are easily displaced toward the cavity section, or the filter piece is partially sucked out of the outer tube during the suction process; 3. Filling This method limits it to batch filling of individual pipes, and the production efficiency is low.
因此，如果高效率的生产带有空腔结构的颗粒型气溶胶发生制品，且保证封堵件和过滤件的稳定不位移，是颗粒型气溶胶发生制品生产关键需要解决的问题。Therefore, if particulate aerosol-generating products with cavity structures can be produced efficiently and the sealing and filter elements are stable and not displaced, this is a key issue that needs to be solved in the production of particulate aerosol-generating products.
为了解决以上问题，提出本发明。In order to solve the above problems, the present invention is proposed.
发明内容Contents of the invention
本发明先用卷制复合的方式成型除了气溶胶生成颗粒段以外的其余各单元，复合时预留出装填气溶胶生成材料的空腔，复合后再按照需要分切，然后将分切后的带有气溶胶生成基质容纳腔的嘴棒竖直放置，接着再向气溶胶生成基质容纳 腔中装填气溶胶生成材料，本发明先复合后灌装的方法可以大幅度提高生产效率，且保证封堵件2和过滤件4的在抽吸或者运输过程中稳定不位移，以及更好的保持不同样品空腔段轴向长度的一致性。In the present invention, the remaining units except for the aerosol-generating particle segment are first formed by rolling and compounding. During compounding, a cavity for filling the aerosol-generating material is reserved. After compounding, the units are then cut as needed, and then the cut pieces are The mouthpiece rod with the aerosol-generating matrix containing cavity is placed vertically, and then the aerosol-generating material is filled into the aerosol-generating matrix containing cavity.

When there is an empty pipe in the cavity section 3, the vent hole 31 penetrates the composite pipe 1 and the empty pipe at the same time. The purpose of the vent 31 is to introduce air into the cavity section, on the one hand, to reduce the temperature of the aerosol, and on the other hand, to reduce the suction resistance. Therefore, whether the vent 31 is needed is determined based on the actual aerosol temperature and suction resistance. When the ventilation hole 31 needs to be provided, it is preferably punched to form the ventilation hole. Of course, it is also possible to use breathable paper as the composite tube or the empty paper tube in the cavity section instead of drilling, as long as air can be introduced into the cavity section. That’s it.

The adhesive can be selected from ordinary joint glue.
优选地，所述复合管1为纸管、无纺布管。所述复合管1上具有防渗或者导热功能的防渗/导热层(尤其是所述复合管1为无纺布管时)，所述防渗/导热层包括防水层和/或防油层和/或导热层；Preferably, the composite tube 1 is a paper tube or a non-woven tube. The composite pipe 1 has an anti-seepage/thermal conductive layer with an anti-seepage or thermal conductive function (especially when the composite pipe 1 is a non-woven pipe). The anti-seepage/thermal conductive layer includes a waterproof layer and/or an oil-proof layer and /or thermal conductive layer;
防水层采用烷基烯酮二聚体AKD、阳离子松香胶或者无铁硫酸铝混用、石蜡材料；防油层采用碳氟有机物、改性淀粉、AKD和石蜡混合物，AKD和改性淀粉混合物材料。导热层选自但不限于铝箔层，其通过粘贴的方式添加到卷烟纸管内壁；所述铝箔层可以起到防水和/或防油的作用，同时所述铝箔层还具有导热保温的作用，以使卷烟内壁的发烟材料均匀受热。The waterproof layer uses alkyl ketene dimer AKD, cationic rosin gum or a mixture of iron-free aluminum sulfate, and paraffin materials; the oil-proof layer uses fluorocarbon organic matter, modified starch, a mixture of AKD and paraffin, and a mixture of AKD and modified starch. The thermal conductive layer is selected from but not limited to an aluminum foil layer, which is added to the inner wall of the cigarette paper tube by pasting; the aluminum foil layer can play a role in waterproofing and/or oil resistance, and at the same time, the aluminum foil layer also has a thermal conductive and thermal insulation effect.

Therefore, it is necessary to add a waterproof layer to the inner wall of the cigarette paper tube filled with smoking material. The waterproof layer is made of alkyl ketene dimer AKD, cationic rosin gum or a mixture of iron-free aluminum sulfate and paraffin materials, which can prevent moisture in the smoking material from penetrating to the outside of the cigarette paper tube.
同样的，发烟材料中会添加发烟剂、香精香料等，长时间放置过程中，发烟材料中的发烟剂会携带香精香料渗透到纸管外侧，产生黄斑，影响纸管外观，而由于发烟剂是油性的，所以需要对填发烟材料的卷烟纸管的内壁添加防油层。防油层采用碳氟有机物、改性淀粉、AKD和石蜡混合物，AKD和改性淀粉混合物材料，可以防止发烟材料中发烟剂携带香精香料向纸管外壁渗透，防止黄斑的产生。Similarly, smoking materials, flavors and fragrances are added to the smoking materials. When left for a long time, the smoking agents in the smoking materials will carry flavors and fragrances and penetrate into the outside of the paper tube, causing yellow spots and affecting the appearance of the paper tube. Since the smoking agent is oily, it is necessary to add an oil-proof layer to the inner wall of the cigarette paper tube filled with smoking material. The oil-proof layer uses a mixture of fluorocarbon organic matter, modified starch, AKD and paraffin. The mixture of AKD and modified starch can prevent the smoking agent in the smoking material from carrying flavors and fragrances from penetrating into the outer wall of the paper tube and preventing the occurrence of yellow spots.
所述封堵件可以为任何的形式，只要是可以将阻隔气溶胶生成基质(6)使其不向下游移动即可。The blocking member can be in any form, as long as it can block the aerosol-generating matrix (6) from moving downstream.

In the present invention, the remaining units except for the aerosol-generating particle segment are first formed by rolling and compounding. During compounding, a cavity for filling the aerosol-generating material is reserved. After compounding, the parts are cut as needed, and then the parts are cut.

3、本发明利用先复合后灌装的方法制备气溶胶发生制品，可以同时复合多个嘴棒，再分切后灌装气溶胶生成材料，由于除气溶胶生成材料外，其余各单元均是通过复合的形式，相对于单独一个个灌装各单元效率大幅度提高。3. The present invention uses the method of first compounding and then filling to prepare aerosol-generating products. Multiple nozzle rods can be compounded at the same time, and then cut and then filled with aerosol-generating materials. Since except for the aerosol-generating materials, the other units are Through the composite form, the efficiency of each unit is greatly improved compared to filling each unit individually.
4、本发明通过挤入的方式装填流动状气溶胶生成材料，然后使气溶胶生成基质容纳腔5竖直朝下，放置于平面上于一定温度下干燥膨胀，使气溶胶生成材料凝固形成位于所述气溶胶生成基质容纳腔5中的固定状气溶胶生成棒6，利用挤入的方法生产效率更高，且干燥膨胀后得到的气溶胶生成棒6自身带有孔隙结构，利于气溶胶的释放和流通。倒置后放置于平面上于一定温度下干燥膨胀的目的在于使气溶胶生成棒6远离过滤件一端的端面齐平。4. The present invention fills the flowing aerosol-generating material by squeezing in, and then makes the aerosol-generating matrix containing cavity 5 face vertically downward, places it on a flat surface, and dries and expands at a certain temperature, so that the aerosol-generating material solidifies to form an aerosol-generating matrix. The fixed aerosol-generating rod 6 in the aerosol-generating matrix accommodation cavity 5 can be produced more efficiently by extrusion, and the aerosol-generating rod 6 obtained after drying and expansion has a pore structure, which is beneficial to the aerosol generation.
