本申请实施例提供了一种用于制造气溶胶生成制品的模具,请参阅图1至图14,模具100包括沿第一方向依次布置的第一主体10、第二主体20以及第三主体30。

其中混合物从挤出模具100装置挤出成蜂窝体,然后将其干燥以形成最终的蜂窝体状的气溶胶生成制品200的全部或者部分。
请参阅图1至图6,第三主体30形成有沿第一方向延伸的挤出通道30a。挤出通道30a远离第二主体20的一端形成出料口30d,即原料混合物可以通过挤出通道30a挤出而制成各种截面制品或半制品。
请参阅图7至图11,第二主体20设置有第一立柱21和进料通道20a,请继续参阅图4至图6,进料通道20a沿第一方向延伸并与挤出通道30a连通,第一立柱21沿第一方向延伸至挤出通道30a,即原料混合物可以通过进料通道20a进入挤出通道30a,并经出料口30d挤出而制成各种截面的制品或半制品。
请参阅图4至图6、图10以及图11,第一主体10设置有第一型腔10a,第一型腔10a贯穿第一主体10沿第一方向的相对两端并与进料通道20a连通,第一型腔10a远离第二主体20的一端为进料口10b,即原料混合物可以通过第一型腔10a从第一主体10的一端导向另一端。
第一主体10设置有第二立柱11,第二立柱11沿第一方向延伸至挤出通道30a。
示例性地,挤出通道30a沿延伸方向的中心线与模具100沿第一方向的中轴线C重合。
请参阅图4,模具100沿第一方向的中轴线C是一条虚拟的作为参考的基准线。
此处所述的重合是指该挤出通道30a沿延伸方向的中心线与模具100沿第一方向的中轴线C大致重合或者完全重合,也就是说,该挤出通道30a沿延伸方向的中心线与模具100沿第一方向的中轴线C之间可以有一定的偏差,模具100沿第一方向的中轴线C大致穿过该挤出通道30a的中心线。
示例性地,第二立柱11沿延伸方向的中心线与模具100沿第一方向的中轴线C重合。
此处所述的重合是指该第二立柱11沿延伸方向的中心线与模具100沿第一方向的中轴线C大致重合或者完全重合,也就是说,该第二立柱11沿延伸方向的中心线与模具100沿第一方向的中轴线C之间可以有一定的偏差,模具100沿第一方向的中轴线C大致穿过该第二立柱11的中心线。
第二立柱11比第一立柱21更靠近模具100的中轴线C,示例性地,第一立柱21环设在第二立柱11的周侧,即第一立柱21环绕设置于第二立柱11的周侧,第一立柱21沿第二立柱11的周向间隔设置。
请参阅图4至图6,第二立柱11和第一立柱21均沿第一方向延伸至挤出通道30a,第一立柱21环设在第二立柱11的周侧,第二立柱11、第一立柱21以及挤出通道30a的内壁间隔设置,可以用于挤出形成气溶胶生成制品200的壁厚或者中间筋位特征,第二立柱11可以用于挤出形成气溶胶生成制品200的中心孔200a,第一立柱21可以用于挤出形成位于中心孔200a周侧的气道孔200b,挤出通道30a可以用于挤出限定气溶胶生成制品200的外周形状,原料混合物通过挤出通道30a被挤出,挤出的挤出物形成蜂窝体状的制品或半制品(请参阅图12至图14)。
也就是说,第二立柱11的形状可以决定中心孔200a的形状,第一立柱21的形状可以决定位于中心孔200a周侧的气道孔200b的形状,挤出通道30a的形状可以决定气溶胶生成制品200的形状,由此,可以通过不同的第一主体10、第二主体20以及第三主体30之间的搭配,获取不同横截面形状的气溶胶生成制品200。
示例性的,气溶胶生成制品200为颗粒结合体,例如是含发烟剂、烟草等成分的重组烟草介质,通过连续挤出工艺方法成型出的一体式结构。其中挤出成型是指将原料混合物加入到挤出机中,物料通过挤出机料筒和 螺杆间的作用,被螺杆向前推送,连续通过包括本申请实施例的模具100而制成的各种截面制品或半制品的一种加工方法。另外,通过模具100挤出后的制品或半制品可以用于制成气溶胶生成制品200的不同的组成部分,例如降温段、发烟段、支撑段、过滤段等,或者可以直接用于制成整个气溶胶生成制品200,在此不作限制。
在对气溶胶生成制品200进行加热雾化时,气溶胶生成制品200受热释放气溶胶,气溶胶通过各气道孔200b以及中心孔200a间的间隔壁的间隙或微孔流出并归集到气道孔200b以及中心孔200a中,在抽吸负压的作用下输送至抽吸端。
需要说明的是,第一主体10、第二主体20以及第三主体30的材料可以一致,也可以不一致。由于该模具100用于制造气溶胶生成制品200,挤出过程中挤出压力较大,需要模具100具有较高的强度。另外,气溶胶生成制品200的原料混合物含有水分,需要模具100具备一定的抗锈蚀等能力,由此,第一主体10、第二主体20以及第三主体30的材料可以均为高强度不锈钢,如奥氏体不锈钢、马氏体不锈钢等。
本申请实施例中,第一方向是指进料方向。例如,当模具100的外观轮廓呈圆柱形,则第一方向为垂直于模具100的底面的高度方向,或者,第一方向为模具100的轴向。再例如,当模具100的外观轮廓呈长方体时,第一方向仍然是上述定义的方向,即指进料方向,第一方向可以是长方体的长、宽、高的任意一个方向。
另一些实施方式中,当模具100的外观轮廓呈柱形,第一方向还可以与模具100的底面的高度方向倾斜设置,或者,第一方向相对模具100的轴向倾斜设置。当模具100的外观轮廓呈长方体时,第一方向可以相对长方体的长、宽、高的任意一个方向倾斜设置。
又一些实施方式中,第一方向是指进料方向,且第一方向可以是呈折 线状,例如,模具100从侧面进料,并从顶面或者底面挤出;或者,模具100从顶面进料,并从侧面挤出。
本申请实施例提供的用于制造气溶胶生成制品的模具,模具100包括沿第一方向依次布置的第一主体10、第二主体20以及第三主体30,即通过设置第一主体10、第二主体20以及第三主体30,提高模具100加工的便利性。第一主体10设置有第一型腔10a,第二主体20设置有进料通道20a,第三主体30形成有沿第一方向延伸的挤出通道30a,第一型腔10a远离第二主体20的一端形成进料口10b,挤出通道30a远离第二主体20的一端形成出料口30d,即原料混合物可以通过进料口10b依次进入第一型腔10a、进料通道20a、挤出通道30a,并经出料口30d挤出而制成各种截面的制品或半制品。由于第一主体10设置有第二立柱11,第二主体20设置有第一立柱21,第二立柱11和第一立柱21均沿第一方向延伸至挤出通道30a,且第一立柱21环设在第二立柱11的周侧,如此,可以通过控制第二立柱11、第一立柱21、挤出通道30a的形状以及间隙,能够获得不同横截面形状或者尺寸的气溶胶生成制品200,也就是说,可以通过更换第一主体10、第二主体20或者第三主体30中的一个或者两个,就可以获得不同横截面形状或者尺寸的气溶胶生成制品200,不需要更换整个模具100,降低生产成本。另外,可以通过控制第一型腔10a、进料通道20a、挤出通道30a的尺寸来控制模具100的孔隙率,有利于确保挤出过程中形成压力上升,促进气溶胶生成制品200的成型以及提高气溶胶生成制品200的紧密度。
相关技术中,考虑到模具的强度问题,进料端的孔隙率变化范围有限,无法确保进料端的孔隙率一直大于出料端孔隙率,即存在进料端的部分区域的孔隙率小于出料端孔隙率,从而影响气溶胶生成制品的挤出效果和稳定性。
而本申请实施例提供的模具,包括沿第一方向依次布置的第一主体10、 第二主体20以及第三主体30,对于较小孔隙率的气溶胶生成制品200,可以通过修改模具100的特征尺寸(例如第一型腔10a、进料通道20a、挤出通道30a的尺寸,或者第二立柱11、第一立柱21的尺寸或者间隙等),使得挤出通道30a的孔隙率小于进料通道20a的孔隙率,提高气溶胶生成制品200的挤出效果和稳定性,而降低对模具100的强度的影响。
在垂直于第一方向的平面上,位于进料方向上游的进料通道20a的过流断面面积不小于位于进料方向下游的进料通道20a的过流断面面积,如此,可以使得原料混合物在进料通道20a中保持一定的挤压力,或者受到的挤压力逐渐增加,有利于原料混合物的进料。
需要说明的是,过流断面是指与元流或总流所有流线正交的横断面,即垂直于流速簇例如气流或液流的面。当流线簇彼此不平行时,过流断面为曲面;当流线簇为彼此平行直线时,过流断面为一平面。
在垂直于第一方向的平面上,位于进料方向上游的进料通道20a的过流断面面积不小于位于进料方向下游的进料通道20a的过流断面面积的情况有多种,示例性地,一实施例中,进料通道20a的过流断面面积的大小沿进料方向相同,即各进料通道20a是等径的。如此,可以使得原料混合物在进料通道20a中保持一定的挤压力,有利于原料混合物的进料。
另一些实施例中,各进料通道20a的过流断面面积的大小沿进料方向逐渐减小,即各进料通道20a是变径的,且位于进料方向上游的进料通道20a的过流断面面积大于位于进料方向下游的进料通道20a的过流断面面积。如此,可以使得原料混合物在进料通道20a中受到的挤压力逐渐增加,有利于初步捏合原料混合物。
又一些实施例中,还可以是部分进料通道20a的过流断面面积的大小相同,部分进料通道20a的过流断面面积的大小沿进料方向逐渐减小。
在垂直于第一方向的平面上,位于挤出方向上游的挤出通道30a的过 流断面面积不小于位于挤出方向下游的挤出通道30a的过流断面面积,如此,可以使得原料混合物在挤出通道30a中保持一定的挤压力,或者受到的挤压力逐渐增加,以使原料被逐渐捏合成型。
在垂直于第一方向的平面上,位于挤出方向上游的挤出通道30a的过流断面面积不小于位于挤出方向下游的挤出通道30a的过流断面面积的情况有多种,示例性地,一实施例中,挤出通道30a的过流断面面积的大小沿挤出方向相同,即各挤出通道30a是等径的。如此,可以使得原料混合物在挤出通道30a中保持一定的挤压力,有利于促成网格结构的完整捏合。
另一些实施例中,各挤出通道30a的过流断面面积的大小沿挤出方向逐渐减小,即各挤出通道30a是变径的,且位于挤出方向上游的挤出通道30a的过流断面面积大于位于挤出方向下游的挤出通道30a的过流断面面积。如此,可以使得原料混合物在挤出通道30a中进行进一步的挤压,有利于促成网格结构的完整捏合。
又一些实施例中,还可以是部分挤出通道30a的过流断面面积的大小相同,部分挤出通道30a的过流断面面积的大小沿挤出方向逐渐减小。
示例性地,在垂直于第一方向的平面上,挤出通道30a的过流断面面积的最大值小于或等于进料通道20a的过流断面面积的最小值,可以使得原料混合物在挤出通道30a中保持一定的挤压力,或者受到的挤压力逐渐增加。而当挤出通道30a的过流断面面积的最大值小于进料通道20a的过流断面面积最小值,原料混合物通过进料通道20a进入挤出通道30a后,用于使原料混合物在挤出通道30a中进行进一步的挤压,有利于在促成网格结构的完整捏合,且在气溶胶生成制品200的孔隙率一定的情况下,控制气溶胶生成制品200的密度。
示例性地,请参阅图4至图9,第二主体20包括沿第一方向依次布置的第一连接段22和第二连接段23,第一连接段22靠近第一主体10设置且 形成第二型腔20b,第二连接段23设置有进料通道20a和第一立柱21,进料通道20a与第一型腔10a通过第二型腔20b连通。如此,可以使得原料混合物先从第一型腔10a进入第二型腔20b,再经第二型腔20b进入进料通道20a,在第一立柱21沿第一方向的尺寸一定的情况下,缩短进料通道20a的长度,进而减小原料混合物在进料过程中受到的阻力,有利于原料混合物的进料。
当然,第二主体20也可以不设置第一连接段22,也就是说,不设置第二型腔20b,即原料混合物先从第一型腔10a直接进入进料通道20a。
进料通道20a的数量为多个,通过设置多个进料通道20a,在保障进料均匀性的同时,还可以使得原料混合物在挤出通道30a中受到一定的挤压力。
需要说明的是,第一立柱21的数量在此不做限制,例如,第一立柱21的数量可以为一个,第一立柱21的数量也可以为多个。
需要说明的是,本申请实施例中,多个是指数量包括两个以及两个以上。
示例性地,请参阅图3、图6、图9以及图14,各进料通道20a贯穿第二连接段23沿第一方向的相对两端,第一立柱21设置在第二连接段23背离第二型腔20b的一侧。即原料混合物可以通过进料通道20a从第二连接段23的一端导向另一端,第一立柱21设置在第二连接段23背离第二型腔20b的一侧,第一立柱21延伸至挤出通道30a,即原料混合物可以通过进料通道20a进入挤出通道30a,填充至各第一立柱21的间隙之间或者各第一立柱21与挤出通道30a的内壁之间,并经出料口30d挤出而制成各种截面的制品或半制品。
示例性地,请参阅图6以及图9,第二连接段23的内部形成过孔20c,第二立柱11经过孔20c延伸至挤出通道30a,各第一立柱21环设在第二立 柱11的周侧。通过设置过孔20c,便于第二立柱11经过孔20c延伸至挤出通道30a,各第一立柱21设置在过孔20c的周侧,各第一立柱21例如沿环绕第二立柱11的中心的圆周方向排列,以使各第一立柱21环设在第二立柱11的周侧。
示例性地,请参阅图4至图8,第二连接段23的内壁的部分区域沿径向延伸形成第二连接肋24,第二连接肋24远离第二连接段23的内壁的一端与第一立柱21连接。
也就是说,通过设置第二连接肋24,用于连接第一立柱21,且第二连接肋24沿第二连接段23的径向延伸,便于第一立柱21沿第一方向延伸。
需要说明的是,第二连接肋24的数量在此不做限制,例如,第二连接肋24的数量可以为一个,第二连接肋24的数量也可以为多个。
示例性地,请继续参阅图4至图8,第一立柱21和第二连接肋24的数量均为多个,且第一立柱21和第二连接肋24一一对应,多个第一立柱21间隔设置且围设形成过孔20c,第二立柱11经过孔20c延伸至挤出通道30a,各第一立柱21环设在第二立柱11的周侧。

示例性地,请参阅图4至图6,第三主体30包括沿第一方向依次布置的第三连接段31和第四连接段32,第三连接段31靠近第二主体20设置且形成有第三型腔30b,第四连接段32设置有挤出通道30a,进料通道20a和挤出通道30a通过第三型腔30b连通。如此,可以使得原料混合物先从进料通道20a进入第三型腔30b,再经第三型腔30b进入挤出通道30a,第三型腔30b的设置,使得从进料通道20a进入第三主体30的原料混合物可以暂存在第三型腔30b内,当第三型腔30b填满后形成一定挤压力,从出 料口30d挤出,第三型腔30b的设置,有利于原料混合物从进料通道20a进入挤出通道30a。
一般的,在气溶胶生成制品200的横截面形状确定之后,即确定了模具100出料口30d的孔隙率,此时可以通过改变第三型腔30b的尺寸使得第三型腔30b的孔隙率大于出料口30d的孔隙率,从而保证气溶胶生成制品200紧实。
同样的,也可以通过改变第二型腔20b和第一型腔10a的尺寸,以改变第二型腔20b和第一型腔10a的孔隙率,即可通过改变第二型腔20b和第一型腔10a的尺寸,以实现对第二型腔20b和第一型腔10a的孔隙率的控制,提高模具100的可靠性和准确性。

示例性地,请参阅图4至图6、图10以及图11,第一型腔10a的内壁 的部分区域沿径向延伸形成第一连接肋12,第一连接肋12与第二立柱11连接。

当然,在其他实施例中,第二立柱11和/或第一立柱21也可以没有延伸至出料口30d,即第二立柱11和/或第一立柱21的端部位于出料口30d与进料通道20a之间,只要能够使得原料混合物挤出而制成各种截面制品或半制品即可。
需要说明的是,挤出通道30a的形状在此不做限制,示例性地,在垂直于第一方向的平面上,挤出通道30a的横截面形状为圆形(请参阅图1至图3)、椭圆形、跑道形或者多边形。
