Description

一种迷你型纸手帕的制造工艺 技术领域
本发明涉及纸手帕制作的的工艺领域，尤其是涉及一种生产迷你型纸手帕的制造工艺。
 背景技术
纸手帕是一种新型的清洁纸，作用相当于传统的手帕，起擦试作用，以柔软的纸制成。纸手帕由于它的外型小、方便携带，能够吸水、擦去污渍，因而给人们的生活带来了很大方便，成了家家户户爱用的生活用品，深受广大消费者的喜爱。
目前市场上常用的纸手帕尺寸规格一般较为固定，甚至有些包装过大造成携带不便，相应地，生产纸手帕的制造工艺和对应的生产设备也只能生产此种固定规格或者接近于此种规格的纸手帕。
而且，现有的纸手帕生产线中的包装工序处理过程大多需要大量人工来辅助完成。这样的生产方式不仅造成人工成本比较高，生产效率低，速度也很慢，而且生产的纸张规格不可调，形状、尺寸单一，有的纸手帕在装进包装袋内后，常常会因为太大而造成携带不方便，给人视觉上造成不舒适感，生产一种规格更加小型美观、携带更加方便、利用率更加高的超迷你型纸手帕已经成为生产者和消费者的迫切需求，可现有的纸手帕生产工艺已无法满足工业生产的需求。
 技术问题
针对现有技术中存在的上述缺陷，本发明提供了一种迷你型纸手帕的制造工艺，以解决原有的纸手帕折叠加工过程中人工成本较高、生产效率低下、速度较慢，且生产出的纸手帕纸张规格不可调、形状、尺寸单一，携带不便的技术问题。
 技术解决方案

3）纵向折叠：纵向折叠机组将经过所述压花辊压过的纸幅沿其宽度方向折叠成三个折叠面；
4）横向折叠：横向折叠机组将对经过所述纵向折叠机组纵向折叠过的纸幅按照实际需要的长度进行切割，然后再对切割后的纸巾进行二分之一折叠和四分之一折叠；
5）分片：数片器将对经过横向折叠完毕的纸巾按照每个包装袋所需要的数量进行分片处理，使纸巾以一定的数量堆叠排列形成纸巾包；
6）包装：百花盘在其槽口处对进行分片处理后形成的纸巾包进行整理并入包装袋。
进一步地，所述纵向折叠机组包括第一牵引辊、第二牵引辊、第三牵引辊、安装在第一牵引辊和第二牵引辊之间的第一纵向折叠组件、安装在第二牵引辊和第三牵引辊之间的第二纵向折叠组件，其中，

 本发明的最佳实施方式
本发明的实施方式
下面结合附图对本发明做进一步描述，但不作为对本发明的限定。
如图1-A、图10 所示，本发明实施例所述的迷你型纸手帕的制造工艺，包括上纸、压花、纵向折叠、横向折叠、分片以及包装各个步骤。通过设置在机台上依次衔接的纵向折叠机组1、横向折叠机组2和百花盘机组5，纸幅3依次张紧穿设在纵向折叠机组1和横向折叠机组2上，纸手帕通过所述纵向折叠机组1沿宽度方向以”Z”字形折叠成三个折叠面，然后通过所述横向折叠机组2沿长度方向再对折两次，折叠成四个折叠面。具体请看以下步骤：
（1）上纸
在对纸幅3进入折叠机组之前，先进行上纸操作，即：将待生产的纸幅推到液压升降机上，脚踩液压开关将纸幅升起，使纸幅的纸筒芯中央对准盘纸支架，轻轻推动升降机向盘纸支架靠拢，使纸筒芯与盘纸支架的轴完全吻合，然后用固定螺栓将盘纸固定于所述支架上，上纸程序完成。
具体来说，所述纸幅有两种规格范围：当生产线为单排生产线时，纸幅的宽度范围为150mm至190mm；当所述生产线为双排生产线时，纸幅的宽度范围为300mm至380mm。
（2）压花
上纸完成后，再对纸幅进行压花处理，将上述固定好的盘纸的纸头打开，手动打开寸动开关，纸幅从导纸辊缓慢穿过压花辊，压花辊上面设有多个不同的凸起形成不同的图案，纸幅经过压花辊后留下各种相应的图案。
（3）纵向折叠
纵向折叠机组1将经过所述压花辊压过的纸幅3沿其宽度方向折叠成三个折叠面。
请参照图1，所述纵向折叠机组1 包括第一牵引辊11、第二牵引辊12、第三牵引辊13、第一纵向折叠组件14以及第二纵向折叠组件15，其中，所述第一纵向折叠组件14 安装在所述第一牵引辊11和第二牵引辊12 之间，所述第二纵向折叠组件15 安装在所述第二牵引辊12和第三牵引辊13 之间。
参照图2、图3、图4，所述第一纵向折叠组件14 包括第一折叠板141 和第二折叠板142，所述第一折叠板141 上设有第一斜边1411，具体地，第一折叠板141 为直角梯形形状，第二折叠板142 为矩形形状，直角梯形的斜腰即为上述的第一斜边1411，通过第一折叠板141 的斜腰的顶点A 垂直向下做一线段，其长度刚好等于梯形的高，斜腰与第二折叠板142的第一边1421 相互叠加，并且第二折叠板142 的第一边1421 与第一折叠板141 相互叠加的区域留有供纸幅3 穿过的第一缝隙4，第二折叠板142 的第一边1421 与高重合，所述第二折叠板142 的纸幅3 引入端折弯形成第一导引板1422；第二纵向折叠组件15 包括第三折叠板和第四折叠板，其与第一纵向折叠组件14 的结构相同，在位置和方向上有所调整，以便使纸幅能够以“Z”字形折叠，在此不再复述。
纵向折叠时，如图1、图5、图6、图7 所示，纸幅3 在第一牵引辊11的作用下沿第一导引板1422 传输至第一纵向折叠组件14 的第一缝隙4 内，在此过程中，第一导引板1422 用于引导纸幅3 平滑的输送到第一纵向折叠组件14 的第一缝隙4 内，避免纸幅3 被损坏，或者因纸幅3 发生断裂，导致停产；在第一折叠板141 的第一斜边1411 的限制下，纸幅3 沿第二折叠板142 的第一边1421 折叠，随后纸幅3 输送至第二纵向折叠组件15 的第二缝隙内，按照上述原理，纸幅3 纵向方向的另一边被折叠，如图8A、图8B 所示，最终按照纸幅3 的宽度以“Z”字形沿宽度平均折叠成三个折叠面。具体地，在本发明的实施例中，纸幅3 的宽度范围161 至182 毫米，那么相应地第一纵向折叠组件14 中第二折叠板142 的a 边的宽度范围为160 至183 毫米， 第二纵向折叠组件15 中第四折叠板的b 边的宽度范围为52至62 毫米。优选地，a 边的宽度为182 毫米，b 边的宽度为61 毫米。
作为另一种实施方式，如图9A、图9B 所示，纸幅3 沿其宽度按“Z”字形折叠成三个折叠面，第一次折叠纸幅3 宽度的1/4,第二次折叠纸幅3宽度的1/4,那么被折叠后的纸幅3 宽度为原来纸幅3 宽度的1/2。纸幅3 的宽度范围为161 至182 毫米，那么相应地第一纵向折叠组件14 中第二折叠板142 的a 边的宽度范围为为161 至183 毫米， 第二纵向折叠组件15 中第四折叠板的b 边的宽度范围为79 至92 毫米。优选地，a 边的宽度为182毫米，b 边的宽度为91 毫米。完成纵向折叠后，纸幅3 在第三牵引辊13 的作用下输送至横向折叠机组2。
（4）横向折叠
横向折叠机组2将对经过纵向折叠机组1纵向折叠过的纸幅按照需要的长度进行切割形成纸巾，然后再对纸巾进行二分之一折叠和四分之一折叠。
如图10 所示，横向折叠机组2 包括设置在机台上的引纸底刀辊21、与引纸底刀辊21 相切的面刀辊22、折叠主辊23、分别与折叠主辊23 相切的第一折纸辊24 和第二折纸辊25，所述引纸底刀辊21 上设有两个分切底刀211，所述面刀辊22 上设有两个分切面刀221，所述第一折纸辊24 上设有第一折纸刀241 和第一气孔242，所述第二折纸辊25 设有第二折纸刀251和第二气孔252，抛纸辊26 与折叠主辊23 相切后固定安装在机台上。
在横向折叠机组2 中，纸幅3 先被分切成预定要求的长度，然后将纸幅3 的长度对折成二分之一折，然后再对折成四分之一折。具体地，引纸底刀辊21 上装有两个分切底刀211，两个分切底刀211 之间的圆弧长长度为引纸底刀辊21 圆周长的一半，纸幅3 首先进入引纸底刀辊21，在引纸底刀辊21 与面刀辊22 的分切面刀221 之间被分切成段，分切长度等于两个分切底刀211 之间的圆弧长，即等于引纸底刀辊21 周长的二分之一。因为纸手帕的长度范围为149 至187 毫米，那么相应的两个分切底刀211 之间的圆弧长度范围也为148 至188 毫米，那么引纸底刀辊21 的圆周长范围为296 至376 毫米，那么引纸底刀辊21 的圆半径范围为46 至61 毫米。优选地，两个分切底刀211 之间的圆弧长度为186 毫米，引纸底刀辊的圆周长为372毫米，采用单排生产线生产生产时，引纸底刀辊21 的圆半径优选为59.24毫米；当采用双排生产线时，所述引纸底刀辊21 的圆半径优选为88.85毫米，对应地对引纸底刀辊21的圆周长和分切底刀211之间的圆弧长度也做相应调整，在此不作详述。
经过分切后，纸幅3 将被切割成实际需要包装的尺寸并吸附在折叠主辊23 上面，随折叠主辊23 一起沿顺时针方向运动，第一折纸辊24 上设有用于吸附纸幅3 头部的第一气孔242，还设有第一折纸刀241。如图10 所示，第一气孔242 与第一折纸刀241 之间的圆弧长理论值为纸幅3 长度的二分之一，此时不考虑第一气孔242 的开口大小，将第一气孔242 与第一折纸刀241 视为一个点，当纸幅3的头部与第一折纸辊24 的第一气孔242 接触瞬间，纸幅3 被吸附到了第一折纸辊24 上，随第一折纸辊24 沿逆时针方向运动，当纸幅3 被吸附在第一折纸辊24 上的长度等于纸幅3 总长度的一半后，第一气孔242 泄气，纸幅3 不被吸附且不随第一折纸辊24 运动，与纸幅3 的后一半折叠重合随折叠主辊23 沿顺时针方向运动。第一气孔242 与第一折纸刀241 之间的圆弧长度范围为69 至96 毫米，优选地，第一气孔242 与第一折纸刀241 之间的圆弧长度为92 毫米。
经过二分之一折叠后，纸幅3 被吸附在折叠主辊23 上面，随折叠主辊23 一起沿顺时针方向运动。第二折纸辊25 上设有用于吸附纸幅3 头部的第二气孔252，还有设有第二折纸刀251。第二气孔252 与第二折纸刀251 之间的圆弧长理论值为纸幅3 长度的四分之一，此时不考虑第二气孔252 的开口大小，将第二气孔252 与第二折纸刀251 视为一个点。当纸幅3 的头部与第二折纸辊25 的第二气孔252 接触瞬间，纸幅3 被吸附到了第二折纸辊25 上，随第二折纸辊25 沿逆时针方向运动，当纸幅3 被吸附在第二折纸辊25 上的长度等于纸幅3 总长度的四分之一后，第二气孔252 泄气，纸幅3 不被吸附且不随第二折纸辊25 运动，与纸幅3 的后四分之一折叠重合随折叠主辊23 沿顺时针方向运动。第二气孔252 与第二折纸刀251 之间的圆弧长度范围为34 至49 毫米，优选地，第二气孔252 与第二折纸刀251之间的圆弧长度为47 毫米。
经过四分之一折叠后，纸幅3 被制作成合适的尺寸，进入抛纸辊26 与折叠主辊23 之间被挤压，使折叠效果更佳。
（5）分片
数片器7将对横向折叠完毕形成的纸巾按照每个包装袋所需要的数量进行分片处理，使纸巾以一定的数量诸如每包4—10片等堆叠排列形成纸巾包。
（6）包装
百花盘机组5在其槽口51处对进行分片处理后形成的纸巾包进行整理后并入包装袋。
如图11 所示，百花盘5 的槽口51 深度为37 至48 毫米，宽度为17 至19 毫米。优选地，百花盘5 的槽口51 深度为47 毫米，宽度为18 毫米，这样，纸幅3 经过折叠后形成的纸手帕在经过堆叠后形成的纸巾包6 刚好容纳在槽口51 内，尺寸得到限制和约束。
包装完毕后，我们可以在所述包装袋的其中一面贴上半月贴，方便取出纸巾，不用的时候贴紧半月贴，防止异物进入包装袋影响纸巾的干净和卫生。
本发明通过上述工艺并基于上述工艺在所述机台上设有依次衔接的纵向折叠机组1、横向折叠机组2 和百花盘机组5，不仅生产效率高，速度快，降低了生产成本，而且生产的纸张规格可根据市场需要进行调整，产品携带方便，更加小巧精美。并通过对纵向折叠机组、横向折叠机组以及数片机的组件进行微小改进，使其相互之间运作更加协调顺畅，工艺故障少，不仅提高了生产产量，而且生产出的纸巾质量也较好，折叠工整，残次损耗较低。
值得注意的是，以上所述仅为本发明的较佳实施例，并非因此限定本发明的专利保护范围，本发明还可以对上述各种零部件的结构进行等效的改进。故凡运用本发明的说明书及图示内容所作的等效结构变化，或直接或间接运用于其他相关技术领域均同理皆包含在本发明所涵盖的范围内。
