Description

干法造纸法再造烟叶薄片整装生产线 技术领域
本发明属于卷烟行业再造烟叶技术领域，涉及一种干法造纸法再造烟叶薄片整装生产线。
背景技术
目前，烟叶薄片的生产主要是基于湿法造纸方法，由于湿法造纸需要使用大量的水，这就需要消耗大量的能源用于水供给，且生产产生的污水不能得到完全有效处理，通常每生产1吨烟叶薄片成品需排放60吨以上高浓、并且含有一定浓度烟碱等物质的废水，对此类废水处理国内外目前均存在难彻底、运行成本高、工程投资大等问题。此外，湿法造纸生产烟叶薄片利用水进行原纸纤维铺网，细小纤维会随水从网孔中流失，造成浪费，原料利用率不高，产品均匀性不好，质量难以控制。
而基于干法造纸方式的再造烟叶工艺是一种全新的烟叶再造生产技术，该方法采用净化空气作为烟草纤维分散和输送介质，从源头上解决传统湿法再造烟叶产生的大量工业废水和耗能大的问题，同时由于干法再造烟叶特殊工艺，使得干法再造烟叶均匀分布大量微孔结构，使烟片更加柔软、蓬松，并具有良好的加工性能和填充性能。
国内外已公开的专利和文献中，关于干法造纸法再造烟叶的方法有多种，但基于此种方法的整装生产线，于再造烟叶生产领域尚未发现。

如图13所示，薄片成型部主要设备为模切机，薄片成型部包括烟叶辊41、模切辊42和传送带43。模切辊42位于烟叶辊41和传送带43之间，烟叶辊41设置在第四网带46的运行末端，烟叶辊41上的再造烟叶卷通过模切辊42得到烟叶薄片成品由传送带43运出。
接下来，将说明本发明的干法造纸法再造烟叶薄片整装生产设备的工作原理。木浆或是烟草纤维或是木浆和烟草纤维的混合物通过原料输送机1，按一定控制量进入粗破碎机2，被初步破碎成邮票大小的不规则块状。然后， 被输送到精破碎机3，在精破碎中进一步破碎成分散的纤维状。破碎后的纤维或是纤维与烟草混合物经过旋风除尘器4，将其中没有被分散的团块状不合格纤维分离出来；分离后的不合格物进入粗破碎机2再次进行破碎利用。合格的纤维经过旋风除尘器4后被送到储料罐5存储待用，储料罐5中的原料被送到计纤机6，经计纤机6按要求的量计量由供料风机7送到成型头12中的两个独立冲孔结构转鼓式圆筛10中。通过圆筛10的转动和打散辊11的打散后，纤维经由圆筛10上的孔中落下到成网带9上，在这一过程中正压风机22提供原料下落的必要的正压强，加湿室21提供消除成型头内部运转产生的静电所要求的空气湿度，负压风机23提供原料下落到第一网带9上所需的负压强。通过负压风机23抽吸在第一网带9上形成负压层，加上正压风机22从上方加压，通过打散辊11打散后的纤维经圆筛10的小孔中均匀落到第一网带9上最终形成松散的纸幅。
接下来，松散的纸幅经过压紧轮15，在90－100℃，压力0.8－2MPa压强下加压成为具有一定强度的可以输送的纸幅，经过转移装置25转移到上喷胶部第二网带44上面。上喷胶装置27给纸面按工艺要求进行喷胶，这时喷的是纸面的正面，喷胶后的纸被第二网带44送入上烘干箱29，上烘干箱29内部温度由烘箱循环风机34以及换热器33控制在90－150℃，烘干后的纸幅经由第二网带44通过下吸风箱26和上吸风箱35转移到下喷胶部。这时，第三网带45在纸幅的上面，而下喷胶装置48则在纸幅的下面，对纸幅进行反面喷胶，即下喷胶。喷过胶的纸幅随第三网带45进入下烘干箱49，下烘干箱49内部温度由烘箱循环风机34以及换热器33控制在90－150℃。烘干后的纸幅经由第三网带45通过下吸风箱59转移到上喷涂部，这时第五网带55在纸幅的下面，通过与上喷胶装置27结构相同的上喷涂装置56对纸幅上面进行上喷涂处理。喷涂后的纸被第五网带55送入上烘干箱57，烘干箱57内部温度由烘箱循环风机34以及换热器33控制在90－150℃。烘干后的纸幅经由第五网带55通过上吸风箱62转移到下喷涂部，这时第六网带61在纸幅的上面，而下喷涂装置63则在纸幅的下面，对纸幅进行反面喷涂，即下喷涂。喷涂后的纸被第六网带61送入下烘干箱64，下烘干箱64内部温度由烘箱循环风机34以及换热器33控制在90－150℃。烘干后的纸幅经由第六网带61通过下吹风箱66和下吸风箱52转移到后处理部，这时，薄片已经形成完成，薄片在第四网带46的上方进入后处理烘箱进行水分的最后控制。完成后的烟草薄片在烟叶辊41上卷成再造烟叶卷，烟叶卷进入模切辊42被模切成要求的大小和形状，经由传送带43传送到收集地点。在这一过程中也可以不生成再造烟叶卷，而烟叶薄片直接由第四网带46进入模切 辊42被模切成要求的大小和形状，经由传送带43传送到收集地点。
