Description

一种分组加工的加热不燃烧烟支结构及制作方法 技术领域
本发明涉及新型烟草技术领域，尤其是，本发明涉及一种分组加工的加热不燃烧烟支结构及制作方法。
 背景技术
加热不燃烧烟支(也称加热卷烟)是新型烟草制品中市场接受度较高的一类产品。加热烟草介于传统卷烟和雾化电子烟之间，其通常包括滤嘴段、冷却段和发烟段。发烟段中的烟草基质不参与燃烧，通过加热方式产生雾化气溶胶，具有与烟草较接近的香气和烟碱释放行为，但是烟气中有害物质成分含量大大降低，相关研究和产品的低危害暴露特性已经得到美国等监管机构认可。
现有的加热不燃烧烟支中的发烟段大部分都是针对导热率和加热性能的设计，以求加热不燃烧烟支插入点烟器具中时可以更好的加热，以便于抽吸，例如中国专利发明专利CN112401297A提供一种加热不燃烧烟支及其制备方法。该加热不燃烧烟支包括沿所述加热不燃烧烟支的长度方向排布的滤嘴段和发烟段，所述发烟段包括管状的片材、位于所述片材内侧的第一发烟基质，所述第一发烟基质的形状稳定且沿所述加热不燃烧烟支的长度方向延伸，所述第一发烟基质的中部形成第一空腔，所述第一空腔在所述第一发烟基质的顶面和底面形成开口，所述第一空腔用于容纳加热元件；除所述第一空腔外在所述片材内侧还存在沿所述加热不燃烧烟支的长度方向延伸的第二空腔，在所述第二空腔内设置有第二发烟基质，所述第一发烟基质的导热率大于所述第二发烟基质的导热率。该加热不燃烧烟支的发烟段受热时温度均匀，吸阻精确可调，且制备工艺简单。
 技术问题
但是上述加热不燃烧烟支结构依然存在以下问题：1、很多不同类型的卷烟纸加工，纸基材料基本相同或相似，不同的仅仅是卷烟纸的导热基质不同，加热不燃烧烟支的种类越来越多，不同种类烟支切换加工时，必须对设备进行校准调节，从而降低了生产效率；2、加热不燃烧烟支燃烧时，部分焦油会渗到烟支外侧，使得烟支变黄或者发黑，一来影响美观，而来渗出的焦油会污染下一个抽吸的烟支，抽吸体验差。
因此为了解决上述问题，设计一种合理高效的分组加工的加热不燃烧烟支结构对我们来说是很有必要的。
 技术解决方案
本发明的目的在于提供一种设置简单，将加热不燃烧烟支的外层纸分为多层结构，先将多层纸分组加工，然后逐层包覆，分组加工方式下，基础纸张相同而添加的功能层不同，即可适用于不同规格不同烟支进行加工，生产效率高；且多层纸上分别添加铝箔使得温度均匀和吸附层使得焦油不会渗出，可以有效提高烟支抽吸体验的分组加工的加热不燃烧烟支结构。
为达到上述目的，本发明采用如下技术方案得以实现的：
一种分组加工的加热不燃烧烟支结构，包括设置于烟丝外侧的内层卷烟纸以及设置于所述内层卷烟纸外侧的外层卷烟纸，所述内层卷烟纸为设置有铝箔的不通风纸，所述外层卷烟纸为吸附纸，使得所述内层卷烟纸和外层卷烟纸加工时为分组加工，并在卷烟制作时先后包覆于所述烟丝外侧。
作为本发明的优选，所述内层卷烟纸和外层卷烟纸之间设置有辅热条，所述辅热条的数量至少为一个。
作为本发明的优选，所述辅热条为金属质件。
作为本发明的优选，所述内层卷烟纸内侧设置有铝箔层，所述铝箔层均匀绕所述烟丝设置。
作为本发明的优选，所述外层卷烟纸包括吸附层和设置于所述吸附层远离所述内层卷烟纸的一侧的阻挡层，所述吸附层为纤维质件，所述阻挡层为不透气件。
作为本发明的优选，所述烟丝内侧设置有中心加热棒，所述中心加热棒包括设置于外侧的外层纸、设置于所述外层纸内侧的内层纸以及设置于所述内层纸内侧的功能棒，所述外层纸和内层纸加工时也是分组加工设置，并在卷烟制作时先后包覆于所述功能棒外侧，再设置于所述烟丝内侧。
作为本发明的优选，所述中心加热棒的数量至少为一个。
作为本发明的优选，所述外层纸为铝箔纸，所述内层纸为吸附纸，所述功能棒为阻燃件。
本发明还提供一种分组加工的加热不燃烧烟支结构的制作方法，包括以下步骤：
S1：获取烟丝种类，选用需求的内层卷烟纸和外层卷烟纸，进行分组加工；
S2：在烟丝外侧包覆内层卷烟纸，且内层卷烟纸中设置有铝箔的一侧位于内侧；

作为本发明的优选，在执行步骤S2之前，在烟丝内侧填充中心加热棒，中心加热棒的外层纸和内层纸也是分组加工，并先后包覆于功能棒外侧。
 有益效果

以下对至少一个示例性实施例的描述实际上仅仅是说明性的，决不作为对本发明及其应用或使用的任何限制。
对于相关领域普通技术人员已知的技术、方法及系统可能不作详细讨论，但在适当情况下，技术、方法及系统应当被视为本说明书的一部分。
实施例一：如图1所示，一种分组加工的加热不燃烧烟支结构，包括设置于烟丝4外侧的内层卷烟纸1以及设置于所述内层卷烟纸1外侧的外层卷烟纸2，所述内层卷烟纸1为设置有铝箔的不通风纸，所述外层卷烟纸2为吸附纸，使得所述内层卷烟纸1和外层卷烟纸2加工时为分组加工，并在卷烟制作时先后包覆于所述烟丝4外侧。
在本发明中，烟丝4可以理解为传统烟丝和新型的发烟的材质，可以称之为发烟丝，将包覆于发烟丝外侧的卷纸分为多层结构，即外层卷烟纸2和内层卷烟纸1，两者分组进行加工，加工完毕之后再依次包覆于发烟丝的外侧形成加热不燃烧烟支结构。
首先是内层卷烟纸1的结构，所述内层卷烟纸1为设置有铝箔的不通风纸，内层卷烟纸1有两种设计方式，第一种就是内层卷烟纸1本身就是铝箔纸，第二种就是内层卷烟纸1为复合有铝箔层的纸张；一般来说，为了方便分组加工，以及后续的逐层包覆，内层卷烟纸1最好选取第二种设计方式。
也就是内层卷烟纸1内侧设置有铝箔层，所述铝箔层均匀绕所述烟丝4设置，可以使得烟支加热时实现圆周加热，烟支的加热更均匀，抽吸效果更好。
然后是外层卷烟纸2结构，所述外层卷烟纸2为吸附纸，外层卷烟纸2也可以有两种设计方式，第一种就是外层卷烟纸2自身就是带有吸附功能的纸张，第二种是复合有吸附层的纸张；一般来说，为了增加外层卷烟纸2的设计功能，最好选取第二种设计方式。
也就是，所述外层卷烟纸2包括吸附层21和设置于所述吸附层21远离所述内层卷烟纸1的一侧的阻挡层22，所述吸附层21为纤维质件，可以更好的吸附加热烟支时渗出的焦油；所述阻挡层22为不透气件，防止吸收了焦油的吸附层21漏出，也可以有效阻隔吸附层21与点烟设备接触污染点烟设备。
甚至可以认为，外层卷烟纸2也是多层分组加工设置，即阻挡层22和吸附层21是分组加工，只不过这两者在包覆在内层卷烟纸1外侧之前要先进行复合，也就是吸附层21与阻挡层22的紧密性大于吸附层21与内层卷烟纸1的紧密性。
最后是内层卷烟纸1和外层卷烟纸2的配合，使得所述内层卷烟纸1和外层卷烟纸2加工时为分组加工，并在烟支制作时先后包覆于所述烟丝4外侧。
先在烟丝4外侧包覆内层卷烟纸1，使得内层卷烟纸1靠近铝箔层的一侧位于内侧；然后在内层卷烟纸1外侧包覆外层卷烟纸2，使得外层卷烟纸2靠近吸附层21的一侧位于内侧。
一般来说，内层卷烟纸1和外层卷烟纸2都有很多规格，只是铝箔纸的厚度不同，吸附层21的密度不同，以及阻挡层22的材质不同而已，在制备指定的烟支时，选取对应的内层卷烟纸1和外层卷烟纸2进行包覆即可。
总之，本发明一种分组加工的加热不燃烧烟支结构的制作方法包括以下步骤：先获取烟丝种类，选用需求的内层卷烟纸和外层卷烟纸，进行分组加工；然后在烟丝外侧包覆内层卷烟纸，且内层卷烟纸中设置有铝箔的一侧位于内侧；最后在内层卷烟纸外侧包覆外层卷烟纸，使得外层卷烟纸设置有吸附层的一侧朝向内层卷烟纸。
本发明一种分组加工的加热不燃烧烟支结构设置简单，将加热不燃烧烟支的外层纸分为多层结构，先将多层纸分组加工，然后逐层包覆，分组加工方式下，基础纸张相同而添加的功能层不同，即可适用于不同规格不同烟支进行加工，生产效率高；且多层纸上分别添加铝箔使得温度均匀和吸附层使得焦油不会渗出，可以有效提高烟支抽吸体验。
实施例二，如图2所示，仅为本发明的其中一个实施例，在实施例一的基础上，本发明一种分组加工的加热不燃烧烟支结构中，所述烟丝4内侧设置有中心加热棒5，所述中心加热棒5包括设置于外侧的外层纸51、设置于所述外层纸51内侧的内层纸52以及设置于所述内层纸52内侧的功能棒53，所述外层纸51和内层纸52加工时也是分组加工设置，并在卷烟制作时先后包覆于所述功能棒53外侧，再设置于所述烟丝4内侧。
中心加热棒5起到中心加热的效果，与内层卷烟纸1中的铝箔造成的圆周加热相配合，使得烟支加热更均匀；当然，所述中心加热棒5的数量至少为一个。
以及，所述外层纸51为铝箔纸，所述内层纸52为吸附纸，所述功能棒53为阻燃件。可以理解为外层纸51和内层纸52的分布与内层卷烟纸1和外层卷烟纸2的分布是相反的，即内层卷烟纸1和外层纸51是起到加热的效果；内层纸52和外层卷烟纸2是起到吸附阻隔的效果。
所述功能棒53为阻燃件，可以使得中心加热棒5可回收再次利用。
实施例三，仍如图1、2所示，仅为本发明的其中一个实施例，在实施例一的基础上，本发明一种分组加工的加热不燃烧烟支结构中，所述内层卷烟纸1和外层卷烟纸2之间设置有辅热条3，所述辅热条3的数量至少为一个。
而且，所述辅热条3为金属质件。
实施例四，如图3所示，本发明还提供上述所有实施例中的一种分组加工的加热不燃烧烟支结构的制作方法，包括以下步骤：
S1：获取烟丝种类，选用需求的内层卷烟纸和外层卷烟纸，进行分组加工；
S2：在烟丝外侧包覆内层卷烟纸，且内层卷烟纸中设置有铝箔的一侧位于内侧；
S3：在内层卷烟纸外侧包覆外层卷烟纸，使得外层卷烟纸设置有吸附层的一侧朝向内层卷烟纸。
还有，在执行步骤S2之前，在烟丝内侧填充中心加热棒，中心加热棒的外层纸和内层纸也是分组加工，并先后包覆于功能棒外侧。
本发明一种分组加工的加热不燃烧烟支结构及制作方法设置简单，将加热不燃烧烟支的外层纸分为多层结构，先将多层纸分组加工，然后逐层包覆，分组加工方式下，基础纸张相同而添加的功能层不同，即可适用于不同规格不同烟支进行加工，生产效率高；且多层纸上分别添加铝箔使得温度均匀和吸附层使得焦油不会渗出，可以有效提高烟支抽吸体验。
本发明不局限于上述具体的实施方式，本发明可以有各种更改和变化。凡是依据本发明的技术实质对以上实施方式所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围。
