Description

一种纸塑整体瓶子、成型模具、设备和生产工艺 技术领域
本发明涉及纸塑成型产品的成型技术领域，特别涉及到纸塑整体瓶子的模具、设备、工艺以及产品的开发。
背景技术
自从工业化时代以来，塑料产品在生活中普遍存在，由于其制作成本非常低，塑料包装材料在世界市场中的增长率高于其他包装材料。塑料作为一种不可降解材料，其对环境造成诸多污染包括回收价值低、影响农业发展、对动物生存构成威胁、占用土地资源、毒害物质的析出等，多个国家要求禁塑，中国也于2020年又一次颁布禁塑令。减少甚至禁止塑料材料的使用是当前包装设计的方向。
现有的纸塑瓶子类产品的工艺都是采用两个半边的瓶子成型后采用胶水进行粘合或者采用纸筒再粘合瓶口和瓶底，其工艺为成型，涂胶，压合，切余边，如专利CN201320746431公开了一种纸塑瓶体，包括瓶身与设于瓶身上部的塑料端头，所述瓶身为向上开口的纸筒，所述塑料端头下部边缘与所述纸筒的开口紧密接合以封闭纸筒内腔；专利CN 201420833805公开了一种具有连接环的储液瓶，包括纸瓶，所述纸瓶的内部设置有用于储存液体的内胆，纸瓶包括相对设置的第一半腔体和第二半腔体，第一半腔体和第二半腔体对接形成用于容纳所述内胆的内腔，之间通过连接环固定连接。上述工艺流程较长、工艺复杂、成本高，且其中涂胶不容易分解，导致环保性差。为了降低纸塑瓶子的成本，并提高环保性，满足环保要求，本发明设计出一种整体纸塑瓶子成型工艺。本发明的整体纸塑瓶子成型工艺仅有成型、切废料两步，减少了涂胶压合等工艺，大大提高产品的环保性能，并降低纸塑瓶子的成本，便于大批量的推广。
纸浆模塑的原材料是各类纤维类材料，来源广泛、容易收集，不会对环境和回收造成障碍，除优良的环境性能，纸浆模塑成型性良好，因其生产工艺依托于模具的发展，所以可以制成多种形状以满足要求。但由于纸的特性，接触液体后很快会被润湿失去其作用，如何既减少塑料的使用达到环保要求，又让瓶子实现长时间存储液体的需要，成为本发明研发的重点。

实施例5
本实施例为本发明纸塑瓶子外壳与塑料内胆结合生产整体瓶子的实施例。
如图4，本设备分为纸瓶外壳成型区51，纸瓶外壳切割区52，塑料瓶坯区54和内胆装入区53。纸瓶外壳区分为吸浆区和热压成型区，吸浆区形成瓶子湿坯，通过热压成型区成型后形成整体纸瓶外壳。通过切割区切割达到统一标准尺寸的纸瓶在内胆装入区与塑料内胆结合，最后形成完整的纸瓶。
纸瓶外壳成型区分为两种吸浆方式：
吸浆方式一：本设备设置了两个吸浆模，初始时吸浆B模2在浆池内，工作时吸浆A模3向下运动与吸浆模B2合并为整体吸浆模，真空开启吸浆。待内部纸瓶湿坯成型，整体吸浆模向上运动至浆池水平面上方，吸浆模B2真空关闭，吸浆模A3真空持续开启，然后两吸浆模分离，吸浆模B2下行至初始位置，纸瓶湿坯1在吸浆模A3上。如图5，此时热压模A4顺滑轨向吸浆模移动，从竖直方向转为水平方向，吸浆模A3下行与热压模A4接触，吸浆模A3真空关闭，热压模A4真空开启，纸瓶湿坯1转移至热压模A4中，然后热压模A4顺滑轨恢复原位与热压模B5接触。如图8，挤压模下行，至弹性构件6装入瓶内，挤压模中有高温液体和加压腔，将高温液体加压充至弹性构件中，弹性构件会膨胀伸展变大，使纸瓶湿坯紧贴于热压模内腔中定型，通过弹性构件的高温和热压模的高温使其干燥。待纸瓶含水率到达标准，挤压模加压腔停止加压，高温液体回流，弹性构件缩小，挤压模向上抬起离开热压模恢复原位。如图9，热压模B5真空开启，与热压模A4分离，顺滑轨向辊轮移动，从竖直方向转为水平方向，移动至辊轮7上齿状结构71伸入纸瓶1内一定距离，辊轮7带动瓶子转动，将其带到传送带上，热压模B5顺滑轨恢复原位，继续与热压模A4合模生产。
吸浆方式二：如图6，设置两个吸浆模，初始时两吸浆模合并位于浆池上方，工作开始后，整体吸浆模下行直至浸没于浆池内，两吸浆模真空开启，直至湿坯形成。如图7，两吸浆模上行，到达指定位置后停止，吸浆模A22停止真空抽气，吸浆模B32持续开启真空，吸浆模B32逆时针旋转45°，两吸浆模分离。吸浆模B沿45°方向下行，直至辊筒13的齿形结构131伸入到湿坯1中，吸浆模B32真空关闭，恢复原位继续下次生产。
纸瓶切割部分：
如图10，成型工序送到传送带上的纸瓶产品1，由环形排列的机械手81一一夹持，机械手旋转至切割件9处切至统一高度。切割好的纸瓶外壳1机械手81放到下一传送带。
内胆组合部分：
如图11，经切割后的纸瓶1经由传送带送至内胆组合工序，一定数量的纸瓶到达指定位置后，两侧吹塑模具10向纸瓶1方向结合，由此纸瓶1被放入吹塑模具10中；预制的塑料瓶胚12预热后经由相应轨道向吹塑模塑移动，而后由吹塑头11夹持伸入纸瓶内至瓶胚定位处与纸瓶相碰进行吹塑。处理好的纸瓶产品1进行收集、仓储。
下表为本发明实施例5制备的塑料内胆整体瓶子的性能测试结果。
Figure PCTCN2021094157-appb-000001
制作的纸瓶结构采用外壳采用100％纸塑产品做强度支撑，内胆采用0.1mm～0.05mm厚度的塑料起到保护液体以及达到安全性(食品安全性，日化产品等领域)并解决了纸对液体渗透等问题，减少塑料70％以上。
以上所述仅为本发明的优选实施例而已，并不用于限制本发明，凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
