Description

一种三角形间隔填充丝束的滤棒及其加工方法 技术领域
本发明属于烟草技术领域，具体涉及一种三角形间隔填充的滤棒及其加工方法。
背景技术
随着烟草行业市场竞争的加剧，单一功能的烟用材料已经难以满足卷烟品牌发展和产品特色化的需求。伴随着新技术、新工艺、新材料在卷烟产品中的应用，烟用材料已由单种功能向多功能、多元化方向发展。滤棒作为卷烟的重要组成部分，随着卷烟市场竞争的日益激烈，外观新颖、功能特殊的卷烟产品受到消费者的青睐，中空滤棒由于特殊的功能在卷烟上的应用越来越多。
卷烟加香的作用在于改善卷烟的理化特性，使消费者获得特定的味觉、嗅觉和触觉的感受，并增进卷烟的可接受性。加香的方法也有很多种，有直接加入烟丝中，也有加到卷烟的其他辅料如过滤嘴、卷烟纸和包装材料中的。微胶囊在烟制品中，放置在滤嘴与烟支接头处，也可以集中放置在滤嘴中段成为滤嘴，在抽吸时发挥着不同的作用，而香料物质保持了原有的风味，同时能够有效地衬托卷烟产品香气，掩盖杂气，改善吸味。
专利CN210076559U公开的中空滤棒的内滤芯纤维丝需要热塑成型、且需要在设有若干减压通道(未填充丝束)；专利CN210382609U的中空滤棒内外层需要设有若干减压通道(未填充丝束)；专利CN105342005A需要设置有多个沟槽的纤维素纸。上述专利的中空滤棒显然是成型纸的折叠形状设计复杂，难于工业化生产，特别是难于一次成型。
为解决上述问题提出本发明。
发明内容
本发明公开了一种内外成型纸间隔填充丝束的三角形滤棒。通过控制丝束类型和丝束添加量，如丝束可以用二醋酸纤维丝束或聚乳酸纤维丝束，可以制备成吸阻较小且过滤效果较好的正三角形滤棒。
本发明的技术方案如下：
本发明第一方面公开了一种三角形间隔填充丝束的滤棒，所述三角形滤棒外观为圆柱状，其组成为外层为外成型纸W卷制成圆筒W1，内层为内成型纸N折叠成的沿圆筒W1的轴向横截面为正三角形N1的筒状；且三角形N1的三个顶点在圆筒W1的内壁面上；其中，外成型纸W和内成型纸N之间填充有外丝束S1，内成型纸N内部填充有内丝束S2。
优选地，外成型纸1的定量为30-40g/m 2。
优选地，内成型纸2的定量为90-110g/m 2。
优选地，三角形21为两层内成型纸2折叠成。
优选地，外丝束S1的单旦为3.9d，总旦为31000d。
优选地，内丝束S2的单旦为3.0d，总旦为32000d。外丝束单旦小于内丝束。
优选地，外成型纸W或/和内成型纸N为加香成型纸。
优选地，外丝束S1或/和内丝束S2为加香丝束。
本发明第二方面公开了所述的三角形间隔填充丝束的滤棒的制备方法，其特征在于，使用滤棒一次成型***；
所述滤棒一次成型***包括如下部件：成型喇叭嘴C、外成型纸传送带3W、内成型纸传送带3N、外丝束传送带42和内丝束传送带52；所述成型喇叭嘴C包括外成型喇叭嘴11和内型喇叭嘴21，内型喇叭嘴21套在外成型喇叭嘴11内；所述外成型喇叭嘴11为半径逐渐变小的圆筒状；所述内型喇叭嘴21为两层，外层211为从圆形逐渐过渡到正三角形的筒状，内层212为一端面积较大的正三角形另一端为面积较小的正三角形的三棱体状；
三角形间隔填充丝束的滤棒的成型方法包括如下步骤：外成型纸传送带3W将外成型纸W传送到成型喇叭嘴C进口处被外成型纸烘烤装置31烘烤后进入外成型喇叭嘴11的圆筒内成型为圆筒WI状，被外搭口胶装置33施胶后从外成型喇叭嘴11的出口处出来，此时从外丝束传送带42传送来的外丝束S1被送入外成型纸W内；同时，内成型纸传送带3N将内成型纸N传送到成型喇叭嘴C进口处被内成型纸烘烤装置32烘烤后进入内成型喇叭嘴21的外层211和内层212之间，逐渐成型为正三角形N1的筒状后，被内搭口胶装置33施胶后从内成型喇叭嘴21的出口处出来；此时从内丝束传送带52传送来的内丝束S2被送入 内成型纸N内；正三角形N1的筒状与外成型喇叭嘴11的出口处出来的圆筒WI套在一起，外成型纸W和内成型纸N之间填充有外丝束S1，内成型纸N内部填充有内丝束S2；成型后的滤棒被粘结胶装置35施胶后粘将三角形N1的三个顶点粘结在圆筒W1的内壁面上，再次被加热器36加热后、再被冷却器37冷却成型，被切刀38分切后由分棒辊39输出，即得到所述的三角形间隔填充丝束的滤棒。
将制备的三角形间隔填充丝束的滤棒做为基棒A，与其它爆珠滤棒、颗粒滤棒、加香滤棒等不同种类的滤棒B按一定顺序和长度比例一次复合即可制备三角形间隔填充丝束二元复合滤棒；基棒A与滤棒B1、B2按一定顺序和长度比例二次复合即可制三角形间隔填充丝束三元复合滤棒。复合滤棒上卷烟机与烟支接装后，三角形间隔填充丝束的滤棒置于烟支唇端。
本发明的有益效果：
1、本发明采用单旦不同的丝束、以及定量不同的内外成型纸，制备出了纸基三角形间隔填充丝束的滤棒，从而实现不同的功能；如中间丝束可以采用高单旦，外层空间采用低单旦丝束，可以提高中间丝束低过滤通透性，提高轻松感，外层空间可以提高过滤效率。而现有技术的方法得到的中空滤棒由于热塑成型内部无法填充丝束，既不能利用现用加香技术差异化加工，也不能起到中空滤棒段的过滤作用。
2、本发明自行设计和制备了成型喇叭嘴。成型喇叭嘴包括外成型喇叭嘴和内型喇叭嘴，内型喇叭嘴套在外成型喇叭嘴内；所述外成型喇叭嘴为半径逐渐变小的圆筒状；所述内型喇叭嘴为两层，外层为从圆形逐渐过渡到正三角形的筒状，内层为一端面积较大的正三角形另一端为面积较小的正三角形的三棱体状。本发明的成型喇叭嘴很容易地将内外成型纸一次成型为所需要的形状。
3、本发明间隔填充丝束的技术方案，配合内外成型纸分隔以及粘结形成的特殊区域，可以实现卷烟烟气特殊过滤作用，增强丝束的协调性和匹配性，提高滤棒的功能性价值。相比于单一丝束填充，丝束过滤效果更加协调，也避免出现同轴滤棒、中空滤棒等形式滤棒过滤丝束或过滤结构、功能的单一性。
4、本发明内外层成型纸粘结在一起，内外层成型纸间隔填充不同的丝束，与目前中空滤棒内部中空结构对烟气流通的位置及机理不同，可以更好将烟气收拢，烟气更加柔和细腻，流畅感好成团，吸味圆润收敛感强。
5、本发明利内外成型纸间隔内外层填充不同的丝束，内外层成型纸特殊内接结构，配合成型纸加香、内层丝束加香，可以更好的发挥丝束的加香作用，更利于卷烟香气聚集，提高卷烟香气质、加强香气量，能够有效提高卷烟感官质量。
