挤出成型是指将物料加入到挤出机中,物料通过挤出机的料筒和螺杆间的作用,被螺杆向前推送,连续通过挤出机出口处的挤出模具而制成各种截面制品或半制品的一种加工方法。挤出成型形成的物料呈条状。
本申请实施例以挤出模具10用于制造气溶胶生成制品中的气溶胶生成介质20为例进行描述,需要说明的是,气溶胶生成制品可以只有气溶胶生成介质20,也可以是气溶胶生成介质20与其它结构的组合,比如,根据需要,气溶胶生成制品还可以在气溶胶生成介质20的一端设置功能段,功能段可以只有过滤功能,也可以具有过滤和降温功能,在一些实施例中,功能段全部或者部分也可以用本申请实施例以挤出模具10制造而成。
气溶胶生成介质20的具体结构在此不做限制,示例性地,一实施例中,气溶胶生成介质20可由雾化介质本身制成,例如由发烟味香料介质制成。另一些实施例中,气溶胶生成介质20也可以包括基体以及设置在基体上的雾化介质,基体例如可以是耐高温的碳纤维,如此,通过设置基体,既可以提高气溶胶生成介质20的强度,还可以承受一定程度的高温而不产生异味。

在一实施例中,粘合剂成分为天然植物提取,非离子化改性粘性多糖,包 括罗望子多糖、普鲁兰多糖、海藻多糖、刺槐豆胶、瓜尔胶、木葡聚糖中的一种或多种组合。粘合剂通过与制品组分材料界面润湿而紧密接触,产生分子间的吸引力,从而起到粘结组分材料的粉体、液体等的作用。同时选用天然植物提取、非离子该性粘合剂,可避免胶体改性带来的甲醇、甲醛、丙烯醛等有害物质的释放,提高制品的安全性。
示例性地,气溶胶生成介质20可以为颗粒结合体,颗粒结合体是一种重组烟草介质,例如是含发烟剂、烟草等成分的重组烟草介质。颗粒结合体的气溶胶生成介质20在受热抽吸或停止受热后均为一体式介质,不易出现崩解掉落的现象,解决了现有技术中的薄片状、丝状或散状颗粒气溶胶生成基质出现如薄片松脱、丝状成分、颗粒成分脱落、不易清洁的问题。
第一型腔10a的第一侧壁10b构造出第一型腔10a的外轮廓。挤出间隙10c是挤出过程中,物料通过的通道。
第一成型柱10d的数量至少为两个,第一成型柱10d向第一型腔10a内凸出于第一侧壁10b,且相邻的两个第一成型柱10d之间限定出第一挤出间隙10c1,也就是说,第一挤出间隙10c1的数量至少为一个。
请参阅图1至图4、图10和图11,在挤出过程中,部分物料从第一挤出间隙10c1处通过,由此使得通过挤出模具10挤出成型的气溶胶生成介质20形成具有介质主体21和凸起结构22,且凸起结构22位于介质主体21外周侧的形态,也就是说,设置第一挤出间隙10c1的目的就是为了形成凸起结构22。
请参阅图3、图10和图11,当第一成型柱10d的数量较多时,位于气溶胶生成介质20外周侧的凸起结构22的数量也相对较多,这些凸起结构22在气溶胶生成介质20的外周侧围设形成齿状。
图1至图4中各第一成型柱10d的外形相同,也就是说,所有的第一成型柱10d都是相同的尺寸和形状。在另一些实施例中,也可以是所有第一成型柱10d中的至少部分第一成型柱10d的外形不同,也就是说,可以是每个第一成型柱10d的外形均不相同,即每个第一成型柱10d至少尺寸和形状中的一个与其它的第一成型柱10d不同,也可以只是部分第一成型柱10d的外形不同,即 部分第一成型柱10d至少尺寸和形状中的一个与其它的第一成型柱10d不同,而其它的第一成型柱10d则是相同的尺寸和形状。
另外,多个第一成型柱10d可以如图3所示的沿第一型腔10a的周向均匀分布,即每相邻的两个第一成型柱10d之间的同一位置处的间距均相同,或者说,所有第一挤出间隙10c1都具有相同的尺寸和形状。多个第一成型柱10d也可以沿第一型腔10a的周向非均匀分布,也就是说,至少部分相邻的两个第一成型柱10d之间的同一位置处的间距与其它相邻的两个第一成型柱10d之间的同一位置处的间距不同,或者说,至少部分第一挤出间隙10c1的尺寸和形状中的至少一个与其它第一挤出间隙10c1不同。
相关技术中,通过挤出模具挤出成型的气溶胶生成介质一般为截面形状为圆形的圆柱状或截面形状为多边形的棱柱状,气溶胶生成介质的形态较单一,因此,最终制成的气溶胶生成制品的形态也较单一。但是,气溶胶生成制品的形态对加热效果以及抽吸体验的影响较大,而目前的气溶胶生成制品在加热过程中,气溶胶无法及时释放出来,气溶胶的提取效率较低。
而本申请实施例的挤出模具10设置了第一型腔10a和多个第一成型柱10d,多个第一成型柱10d设置在第一型腔10a的第一侧壁10b上,且沿第一型腔10a的周向间隔设置。各第一成型柱10d均向第一型腔10a内凸出,以使相邻的两个第一成型柱10d之间限定出第一挤出间隙10c1。在挤出模具10挤出气溶胶生成介质20的过程中,部分物料从第一挤出间隙10c1处通过,以使得挤出成型的气溶胶生成介质20的外周侧可以形成至少一个凸起结构22,也就是说,气溶胶生成介质20的截面形状不再是常规的圆形或多边形,而是呈外轮廓的部分区域向外凸出的形态。通过设置凸起结构22,可以在气溶胶生成介质20外周侧增加供气溶胶释放的空间,比如,当凸起结构22为一个时,位于凸起结构22沿气溶胶生成介质20周向的相对两侧的空间就是增加的供气溶胶释放的空间,当凸起结构22为多个时,相邻的两个凸起结构22之间形成间隔空间就是增加的供气溶胶释放的空间,这些增加的空间可以畅通气溶胶的释放路径,以便于气溶胶快速释放,从而可以较好地提高气溶胶的提取效率。
一实施例中,请参阅图5,第一成型柱10d靠近第一侧壁10b一侧的宽度尺寸D01可以小于第一成型柱10d远离第一侧壁10b一侧的宽度尺寸D02。
第一成型柱10d的宽度尺寸是指第一成型柱10d沿挤出模具10的周向的相对两个表面之间的距离。
也就是说,图5中所示的第一挤出间隙10c1靠近第一侧壁10b一侧的宽度尺寸D11大于第一挤出间隙10c1远离第一侧壁10b一侧的宽度尺寸D12,相应地,请参阅图11,气溶胶生成介质20上的凸起结构22远离气溶胶生成介质20中心的部位的宽度尺寸相对较宽,而靠近气溶胶生成介质20中心的部位的宽度尺寸相对较窄。此种设置方式可以进一步增大供气溶胶释放的空间。
一实施例中,请参阅图3至图5,第一成型柱10d可以包括杆部10d1和主体部10d2,杆部10d1位于第一侧壁10b与主体部10d2之间。杆部10d1的宽度尺寸小于主体部10d2的宽度尺寸。也就是说,在与挤出方向垂直的投影面上,第一挤出间隙10c1的投影大致呈“T”形,相应地,气溶胶生成介质20上的凸起结构22形成图10和图11所示的由横向延伸段221和竖向延伸段222构成的“T”形,由此,可以使气溶胶生成介质20上“T”形的凸起结构22两侧可以形成更大的空间,气溶胶释放和流动也更加顺畅。
一实施例中,请参阅图4和图11,从靠近第一侧壁10b的一侧至远离第一侧壁10b的一侧,相邻两个主体部10d2之间的间距也可以保持不变。也就是说,第一挤出间隙10c1位于相邻两个主体部10d2之间的区域为等宽的结构,或者说,气溶胶生成介质20的凸起结构22上的竖向延伸段222为如图11所示的等宽的结构,此种竖向延伸段222可以降低凸起结构22与介质主体21的相接处出现开裂或断裂的几率。
另一实施例中,请参阅图12和图13,从靠近第一侧壁10b的一侧至远离第一侧壁10b的一侧,相邻两个主体部10d2之间的间距可以逐渐增大,也就是说,第一挤出间隙10c1位于相邻两个主体部10d2之间的区域的宽度尺寸从靠近第一侧壁10b的一侧至远离第一侧壁10b的一侧逐渐增大,或者说,气溶胶生成介质20的凸起结构22上的竖向延伸段222如图12所示的从靠近横向延伸 段221的一端至远离横向延伸段221的一端逐渐增大,由此,可以使得竖向延伸段222与介质主体21相接的部位的宽度尺寸相对较大,进而可以更好地起到防止凸起结构22与介质主体21的相接处出现开裂甚至断裂等情况。
在一些实施例中,第一成型柱10d的宽度尺寸也可以从靠近第一侧壁10b一侧至远离第一侧壁10b一侧逐渐增大,相当于第一成型柱10d的宽度尺寸是连续变化的。
另外,需要说明的是,第一成型柱10d的宽度尺寸并不仅限于靠近第一侧壁10b一侧的宽度尺寸小于远离第一侧壁10b一侧的宽度尺寸,示例性地,从靠近第一侧壁10b的一侧至远离第一侧壁10b的一侧,第一成型柱10d的宽度尺寸也可以逐渐减小,相当于凸起结构22与介质主体21的相接的部位的宽度尺寸相对较大,比如,多个凸起结构22可以共同形成波浪形。
示例性地,从靠近第一侧壁10b的一侧至远离第一侧壁10b的一侧,第一成型柱10d的宽度尺寸也可以保持不变,也就是说,第一成型柱10d是等宽的结构,比如,第一成型柱10d可以是矩形。
一实施例中,请参阅图4、图5、图9、图14至图17,挤出间隙10c可以包括第二挤出间隙10c2和第三挤出间隙10c3,挤出模具10包括具有多个第二挤出间隙10c2的第二成型柱10e,第二成型柱10e设置在第一型腔10a内,且沿挤出模具10的挤出方向延伸,第二成型柱10e与多个第一成型柱10d之间限定出与各第一挤出间隙10c1连通的第三挤出间隙10c3。第二挤出间隙10c2沿挤出方向贯穿第二成型柱10e,且各第二挤出间隙10c2均与第三挤出间隙10c3连通。
具体地,在挤出过程中,部分物料从第三挤出间隙10c3处通过,以用于形成图10、图11和图18所示的第一环形结构211,第一环形结构211是气溶胶生成介质20的介质主体21的一部分,第一环形结构211朝向凸起结构22的外表面相当于是介质主体21的外侧壁,部分物料从第二挤出间隙10c2处通过,以用于形成图10、图11和图18所示位于介质主体21内部的支撑筋212,而支撑筋212之间的区域则形成位于介质主体21内部的气流通道20a。气溶胶生成 介质20内部的气流通道20a可以提高气流在气溶胶生成介质20中的流动速度,从而可以提高气流的冲击力,使气溶胶能得到均匀混合,进而可以提高气溶胶生成介质20中气溶胶的提取效率和均匀性。而支撑筋212可以在气溶胶生成介质20的内部起到较好地支撑作用,以在尽量增大气流通道20a的截面尺寸的同时,提高气溶胶生成介质20整体结构的稳定性。
示例性地,请参阅图16和图17,各第二挤出间隙10c2的一侧分别与第三挤出间隙10c3连通,各第二挤出间隙10c2相对的另一侧可以在第二成型柱10e的中心位置处相互连通,相当于图18中的气溶胶生成介质20的支撑筋212呈从第二成型柱10e的中心位置处向四周扩散的放射状,此种结构形式的气溶胶生成介质20的强度较高,稳定性较好,而且气流通道20a的截面尺寸也相对较大。
在另一些实施例中,各第二挤出间隙10c2也可以设置成其它的形式,比如,各第二挤出间隙10c2之间可以平行或交叉设置,只要能够与第三挤出间隙10c3连通即可。
一实施例中,请参阅图2至图4、图7至图9,挤出间隙10c还可以包括第四挤出间隙10c4,第二成型柱10e可以设置具有第二侧壁10e2的第二型腔10e1,多个第二挤出间隙10c2环绕在第二型腔10e1的周侧,且分别与第二型腔10e1连通。挤出模具10包括设置在第二型腔10e1内的第三成型柱10f,第三成型柱10f沿挤出方向延伸,且与第二侧壁10e2之间限定出第四挤出间隙10c4。
也就是说,各第二挤出间隙10c2分别与第四挤出间隙10c4连通,在挤出过程中,部分物料从第四挤出间隙10c4处通过,以用于形成图10和图11所示的位于介质主体21内部的第二环形结构213,第二环形结构213的内部形成一个气流通道20a,各支撑筋212分别与第二环形结构213相接,第一环形结构211、第二环形结构213以及相邻的两个支撑筋212之间分别限定出其它的气流通道20a。此种结构形式的气溶胶生成介质20同样具有强度较高,稳定性较好,且气流通道20a的截面尺寸也相对较大的特点。
另外,对于中心加热的加热方式,加热组件也可以插入位于第二环形结构 213内的气流通道20a中,以对气溶胶生成介质20从内到外进行烘烤加热。
一实施例中,请参阅图19至图22,挤出间隙10c可以包括第五挤出间隙10c5,挤出模具10可以在第一型腔10a内设置第四成型柱10g,第四成型柱10g沿挤出模具10的挤出方向延伸,且第四成型柱10g与多个第一成型柱10d之间限定出与各第一挤出间隙10c1连通的第五挤出间隙10c5。
具体地,在挤出过程中,部分物料从第五挤出间隙10c5处通过,也可以形成图23所示的第一环形结构211,只是该气溶胶生成介质20的介质主体21的内部没有支撑筋212,而只有一个截面尺寸较大的气流通道20a。
另外,当不同的挤出间隙10c的宽度尺寸差异较大时,各个挤出间隙10c处的压力无法保持相对均匀,也就是说,一些挤出间隙10c处的压力较大,而另一些挤出间隙10c处的压力较小,物料易从压力较小的挤出间隙10c处挤出,而难以甚至无法从压力较大的挤出间隙10c处挤出,因此,为了确保各个挤出间隙10c处的压力相对均匀,以避免物料仅从压力较小的挤出间隙10c处挤出
而降低气溶胶生成介质20的合格率,所有的挤出间隙10c的宽度尺寸应该大致相同或相近。
示例性地,所有挤出间隙10c中,至少一种挤出间隙10c的宽度尺寸可以小于另一种挤出间隙10c的宽度尺寸,挤出间隙10c的宽度尺寸是指挤出间隙10c的相对两个侧壁之间的距离。其中,宽度尺寸最小的挤出间隙10c的宽度尺寸不小于宽度尺寸最大的挤出间隙10c的宽度尺寸的70%。比如,宽度尺寸最大的挤出间隙10c的宽度尺寸为1mm,则宽度尺寸最小的挤出间隙10c的宽度尺寸可以等于0.7mm,也可以大于0.7mm且小于1mm。
以图5所示的挤出模具10为例,相当于图5中的第一挤出间隙10c1的宽度尺寸D11、D12、第二挤出间隙10c2的宽度尺寸D2、第三挤出间隙10c3的宽度尺寸D3以及第四挤出间隙10c4的宽度尺寸D4中至少一种挤出间隙10c的宽度尺寸可以小于另一种挤出间隙10c的宽度尺寸,比如,图5中的第二挤出间隙10c2的宽度尺寸D2、第三挤出间隙10c3的宽度尺寸D3以及第四挤出间隙10c4的宽度尺寸D4相同,而第一挤出间隙10c1的宽度尺寸D1相对较小, 因此,可以将第二挤出间隙10c2、第三挤出间隙10c3和第四挤出间隙10c4中的任意一个作为宽度尺寸最大的挤出间隙10c,而第一挤出间隙10c1是宽度尺寸最小的挤出间隙10c,以第二挤出间隙10c2为例,第一挤出间隙10c1的宽度尺寸D1不小于第二挤出间隙10c2的宽度尺寸D2的70%。
需要说明是的,如果宽度尺寸最小的挤出间隙10c是等宽的结构,则该挤出间隙10c的宽度尺寸就只有一个值,相当于该挤出间隙10c各个位置处的宽度尺寸均相同,如果宽度尺寸最小的挤出间隙10c是非等宽的结构,即该挤出间隙10c部分位置处的宽度尺寸相对较大,部分位置处的宽度尺寸相对较小,则该挤出间隙10c的宽度尺寸是指其所有的宽度尺寸中的最小值。
同样地,如果宽度尺寸最大的挤出间隙10c是等宽的结构,则该挤出间隙10c的宽度尺寸就只有一个值,如果宽度尺寸最大的挤出间隙10c是非等宽的结构,则该挤出间隙10c的宽度尺寸是指其所有的宽度尺寸中的最大值。
示例性地,宽度尺寸最小的挤出间隙10c的宽度尺寸可以为宽度尺寸最大的挤出间隙10c的宽度尺寸的70%、80%、85%、90%、95%。
在另一些实施例中,挤出模具10上所有的挤出间隙10c的宽度尺寸也可以均相同,以图5所示的挤出模具10为例,相当于图5中的第一挤出间隙10c1的宽度尺寸D1、第二挤出间隙10c2的宽度尺寸D2、第三挤出间隙10c3的宽度尺寸D3以及第四挤出间隙10c4的宽度尺寸D4可以均相同,也就是说,不管设置几种挤出间隙10c,每种挤出间隙10c均为等宽的结构,且每种挤出间隙10c的宽度尺寸也均相同,相当于气溶胶生成介质20与各挤出间隙10c对应的部位都具有相同的宽度尺寸。
另外,无论所有的挤出间隙的宽度尺寸是否相同,较优选地,各挤出间隙的宽度尺寸均可以在0.1mm~1.2mm的范围内,比如,各挤出间隙的宽度尺寸可以为0.1mm、0.3mm、0.5mm、0.75mm、0.9mm、1.1mm、1.2mm。
一实施例中,请参阅图1至图3、图6,挤出模具10可以包括第一模具11,第一模具11设置有第一型腔10a和多个第一成型柱10d。
示例性地,请参阅图1至图3、图6、图9,第一型腔10a的一端具有出料 口(图未示出),出料口是物料从挤出模具10挤出的出口,多个第一成型柱10d可以设置在出料口处,也就是说,物料在通过出料口时形成凸起结构22。
一实施例中,请参阅图1至图4、图7、图9,挤出模具10可以包括设置有第二成型柱10e的第二模具12,第二成型柱10e具有多个第二挤出间隙10c2,第二挤出间隙10c2沿第二成型柱10e的延伸方向贯穿第二成型柱10e,且各第二挤出间隙10c2均贯穿第二成型柱10e的外侧壁。第二模具12与第一模具11连接,第二成型柱10e伸入第一型腔10a内,可以理解的是,伸入第一型腔10a之后,第二成型柱10e的延伸方向与挤出模具10的挤出方向为同一个方向。第二成型柱10e与多个第一成型柱10d之间限定出分别与各第一挤出间隙10c1和各第二挤出间隙10c2连通的第三挤出间隙10c3。
第二模具12与第一模具11可以是可拆卸地连接,比如,图1所示的第二模具12与第一模具11通过螺栓15紧固连接。在另一些实施例,第二模具12与第一模具11也可以是不可拆卸地连接,比如,第二模具12可以与第一模具11焊接。
第二模具12与第一模具11连接之后,第二成型柱10e伸入第一型腔10a内,由此形成第三挤出间隙10c3。
一实施例中,请参阅图1至图4、图7至图9,第二成型柱10e设置有具有第二侧壁10e2的第二型腔10e1,多个第二挤出间隙10c2环绕在第二型腔10e1的周侧。挤出模具10还包括设置有第三成型柱10f的第三模具13,第三模具13与第二模具12连接,第三成型柱10f伸入第二型腔10e1,且与第二侧壁10e2之间限定出第四挤出间隙10c4。
第三模具13与第二模具12也可以是可拆卸地连接,比如,图1所示的螺栓15同时穿过第一模具11、第二模具12和第三模具13,以使第一模具11、第二模具12和第三模具13紧固连接,在一些实施例中,第三模具13与第二模具12也可以单独通过螺栓15紧固连接。
在另一些实施例,第三模具13与第二模具12也可以是不可拆卸地连接,比如,第三模具13可以与第二模具12焊接。
一实施例中,请参阅图19至图22,挤出模具10包括设置有第四成型柱10g的第四模具14,第四模具14与第一模具11连接,第四成型柱10g伸入第一型腔10a内,且与多个第一成型柱10d之间限定出与各第一挤出间隙10c1连通的第五挤出间隙10c5。
第四模具14与第一模具11也可以是可拆卸地连接,比如,图19所示的第四模具14与第一模具11通过螺栓15紧固连接。在另一些实施例,第四模具14与第一模具11也可以是不可拆卸地连接,比如,第四模具14可以与第一模具11焊接。
也就是说,第二模具12、第三模具13和第四模具14均可以与第一模具11搭配使用,以组合出不同的挤出模具10,特别是当第一模具11、第二模具12、第三模具13和第四模具14均为可拆卸的结构时,只需要配置一个第一模具11,就可以与第二模具12、第三模具13和第四模具14搭配使用,由此,可以提高第一模具11的通用性,进而可以降低挤出模具10的成本。
在另一些实施例中,挤出模具10也可以不设置第一模具11、第二模具12、第三模具13和第四模具14,比如,挤出模具10可以是一个一体结构,该一体结构的挤出模具10上形成相应的成型柱和挤出间隙10c。
