Description

一种全回收环保包装结构及其制作方法 技术领域
本发明涉及包装领域，具体地说，涉及一种全部采用环保材料制造的全回收环保包装结构及其该包装结构的制作方法。
背景技术
在包装领域，特别是具有缓冲结构的包装结构中，其中的缓冲材料一般采用塑料板、塑胶泡，从而导致无法回收。例如：现有市场上普遍使用的一种包装袋，其袋体是牛皮纸，在牛皮纸的一侧具有塑料覆膜，在塑料覆膜上设置了塑胶泡，而塑胶泡作为缓冲材料。由这种牛皮纸形成的包装结构，其中的塑料覆膜无法分离，塑胶泡也无法分离，所以就会导致包装结构无法回收，无法自然降解，从而污染环境。
在另外一些情况下，缓冲材料也有采用将其他可收回的材料研磨、切割形成粉末状、颗粒状的松软结构，在整个包装结构生产时，将这些的粉末状、颗粒状材料填充，作为缓冲。但是这样的生产过程和工艺，会导致生产环境所在的空气中粉末严重超标，设备要求高，工作人员健康有可能会受到伤害。
发明内容
本发明的目的在于提供一种全回收环保包装结构以及该包装结构的制作方法，旨在解决现有技术中包装结构中缓冲材料不能回收，污染环境以及填充缓冲材料的包装结构工作环境差的技术问题。
本发明提供一种全回收环保包装结构，其包装结构由平面结构折叠封边形成，所述平面结构包括：第一面以及与所述第一面重叠的第二面，和内芯层。
所述内心层夹持于所述第一面与所述第二面之间，且所述内芯层的边缘与所述第一面、所述第二面边缘重合；所述内芯层的边缘与所述第一面以及所述第二面的接触位置通过胶水粘固。所述内芯层包括多层重叠的衬垫，多层所述衬垫的边缘均与所述第一面与第二面边缘平齐。
本发明公开的全回收环保包装结构包括第一面、第二面以及设置于第一面 和第二面之间通过胶水粘固的内芯层，其中内芯层为衬垫，能够作为缓冲层。对于整个包装结构来说第一面、第二面以及内芯层均采用可以回收环保材料制成，克服了现有技术中缓冲层在回收时还需要分离的问题。
本发明同时提供了上述全回收环保包装结构的制作方法，该制作方法包括：步骤S1：准备原材，所述原材包括多卷卷原材；步骤S2：选取至少一卷卷原材，放卷处理后形成衬垫带，并将衬垫带收卷备用；步骤S3：选两卷卷原材以及至少一卷衬垫卷同步进给，并使所述衬垫带位于所述两卷原材放卷的卷材之间，将衬垫带以及原材带贴合，从而形成平面结构带；步骤S4：沿进给方向的平面结构带中间位置折叠，并将垂直于折叠线的两侧边缘位置贴合；步骤S5：沿贴合位置裁切贴合后的平面结构带，从而形成多个包装结构。
本发明公开的制作方法中内芯层采用的衬垫带以及卷原材均采用可回收环保材料制成，例如：可回收纸，克服了现有技术中缓冲材料无法分离，无法回收污染环境的问题。同时，将衬垫作为缓冲的内芯层，克服了现有技术中采用粉末状、颗粒状的松软结构作为缓冲材料，所造成的环境污染，空气质量差的技术问题，同时采用多层衬垫作为缓冲材料，能够达到现有的塑料板、塑胶泡作为缓冲材料的缓冲效果，保证内部物品不损坏的目的。另外，采用本发明制作包装结构时，整个原材制作，包括衬垫带的制作均是在传送带上实现，在多层贴合、折叠、粘固、裁切的过程中，传送带一直处于送给状态，生产的效率较高。

具体实施方式
下面结合具体实施例和说明书附图对本发明做进一步阐述和说明:
请参考图1至图2，本发明公开一种全回收环保包装结构100，该全回收环保包装结构100由平面结构200折叠封边形成，其平面结构200通过加工形成，具体的该平面结构200包括第一面21、第二面22以及内芯层23。其中第一面21与第二面22尺寸大小相同，第一面21重叠于第二面22上。内芯层23夹持于所述第一面21与第二面22之间，且所述内芯层23的边缘与所述第一面21、第二面22边缘重合。彼此接触的第一面21、第二面22以及内芯层23边缘上涂覆有胶水，通过胶水将第一面21、第二面22以及内芯层23固定。此时内芯层23除过边缘部分以外均位于第一面21和第二面22中部，作为一种缓冲层来使用，从而能够保证全回收环保包装结构100内所装的物品的安全，防止损坏。
本发明公开的全回收环保包装结构100包括第一面21、第二面22以及设置于第一面21和第二面22之间通过胶水粘固的内芯层23，其中内芯层23作为缓冲层，整个结构来说第一面21、第二面22以及内芯层23均采用可以回收环保材料制成，克服了现有技术中缓冲层在回收时还需要分离的问题，同时内芯层23本身并不是通过研磨形成的粉末等，不会影响生产环境。
如图1及图3，其中，全回收环保包装结构100由平面结构200沿中间线折叠后，将垂直于中间线的两侧边粘固，并预留一个开口11形成。物品从开口11中放入全回收环保包装结构100中，物品位于缓冲材料的内芯层23的夹持之间，能够有效降低物品损坏的可能。
如图4，在本实施方式中，所述内芯层23包括多层重叠的衬垫231，多层所述衬垫231的边缘均与所述第一面21与第二面22边缘平齐。在本实施方式中，衬垫231本身具有排布整齐的空隙，处于松软状态，采用多层衬垫231叠套的方式能够提高缓冲减震效果。其中，衬垫231本身也是纸质材料，能够可回收，从而不需要单独分离内芯层23。
参阅图4，再有，衬垫231位网状垫纸，网状垫纸生产时，加工也比较简单，仅需要通过整齐排列多行切刀裁切，或者通过模具模切形成裁切缝隙，然 后通过拉伸的方式就可以得到衬垫231，加工简单方便。
当然，在本实用新型的其他实施方式中，该衬垫231也可以是其他的缓冲结构，例如瓦楞形状的垫纸。
进一步地，所述第一面21、第二面22以及内芯层23都是可回收的环保材料，回收再利用时，可以直接回收。其中优选的是内芯层23至少具有3层的衬垫231组成，当然也可以是具有更多层。
请参阅图5及图6，本发明还提供了上述包装结构的制作方法，具体的，该方法包括：
步骤S1:准备原材。
在该步骤中，准备的原材包括多卷卷原材，即准备的原材均是卷材。其中选用的多卷卷原材的材料可以相同，也可以根据不同的需要不完全相同。不过，所选用的卷原材均应是可回收的环保材料，例如可回收、可降解的环保纸质材料。
步骤S2:选取至少一卷卷原材，放卷处理后形成衬垫带，并将衬垫带收卷备用。
在本步骤中，选取的卷原材的数量对应于内芯层中的衬垫带的数量，当需要提高减震效果时，可以增加内芯层中的衬垫带的层数，优选的是将3卷以上的卷原材切割形成衬垫带。
其中，衬垫为网状垫纸，即由镂空结构排布形成。具体的，该网状衬垫带是指将卷材放卷后通过在卷材上切割形成切割刀痕，并在使用时可以通过拉伸是卷材沿切割刀痕拉伸，从而形成网状，松软的网状起到减震的作用。具体的，该切割形成衬垫的方法包括以下的任意一种：
1、卷原材步进进给，切割刀垂直于所述进给方向间隔施刀，从而形成按列间隔排布的一列切割刀痕；所述卷原材再次进给后，同样间隔施刀形成相邻的另一列切割刀痕，并在每次进给后重复切割，纸质卷原材全部进给完成，形成沿卷材长度方向上的多列切割刀痕，进一步形成衬垫带；
需要说明的是：前后两次切割施刀形成的两列刀痕彼此平行，但交错；也就是说，一列切割位置的某个切割刀痕所对应的另一列切割位置为非切割区 域，不具有切割刀痕。
2、当然切割形成衬垫的方法也可以用其他方法形成，例如：卷原材步进进给，每次进给后通过模切刀，对卷原材切割，形成衬垫卷；再次进给后再次切割，直至纸质卷原材全部进给完成形成衬垫带。
在本实施方式中，衬垫模切刀能够通过切割直接形成衬垫带。
当然在本发明的其他实施方式中，衬垫还可以为瓦楞纸，瓦楞纸因为具有凹凸不平的表面，能够起到缓冲作用。当然该瓦楞纸也应该采用可回收环保材料制作。
本制作方法还包括：
步骤S3：选两卷卷原材以及至少一卷衬垫带卷同步进给，并使所述衬垫带位于所述两卷原材放卷的卷材之间，将衬垫带以及原材带贴合，从而形成平面结构带。
在本实施方式中，平面结构带就是平面结构的带状形式，将平面结构带切割后就自然得到平面结构，对平面结构折叠封边后就可以形成所述包装结构。但是在实际生产过程中，并不是首先对平面结构带裁切，具体的该步骤还包括：
步骤S301：设置卷原材以及衬垫带的进给位置，使所述衬垫带放卷的位置位于两卷原材放卷的原材之间。
步骤S302：对衬垫带放卷拉伸，使衬垫带沿切割刀痕位置拉伸，形成网状的衬垫卷带，并进给。
在本步骤中，衬垫带仅是通过切割后能够形成衬垫的带状卷材，在形成衬垫时，需要沿切割刀痕位置拉伸，从而才能形成宽松的网状衬垫，才能将衬垫作为缓冲材料来使用。
步骤S303：向沿进给方向的衬垫的卷带的两侧边喷涂粘固胶水，并通过压合将两原材带以及衬垫卷带压紧粘固，形成平面结构带。
在本步骤中，衬垫的边缘必然是锯齿状，无法保证和作为平面结构第一面和第二面的原材带的边缘完全平齐，不宜采用涂胶的方式。涂胶的方式难以保证所涂胶水的均匀。
在本步骤中，采用喷涂的方式涂覆胶水，将衬垫与卷带的两侧均匀喷上胶 水，还需要说明的是，胶水为树脂胶水，压合时需要向原材带加热，以使所述树脂胶水达到粘固所需要的温度；在未热压合之前，树脂胶水不具有粘贴特性，从而可以在产线工作，折叠之前就喷涂胶水，而不用担心胶水的后期粘贴式，粘结特性的改变无法粘固。
在本实施方式中，采用喷涂树脂胶水的方式能够保证衬垫与卷带两侧胶水均匀，有利于提高固定强度。同时，加热压合的方式压紧卷带与衬垫有利于树脂胶水的固定，提高固定强度。
步骤S4：沿进给方向的平面结构带中间位置折叠，并将垂直于折叠线的两侧边缘位置贴合。
在本发明中，该步骤还包括以下分步骤：
步骤S401：在平面结构带上间隔涂覆胶水，涂覆胶水的位置垂直于所述平面结构带进给方向；
步骤S402：将平面结构带沿进给方向的中间位置折叠，使涂覆胶水的两侧彼此相对，并重合；
步骤S403：压紧折叠后的涂胶位置。其中，压紧时从平面结构带的背面施加压力，也就是说，从平面结构带非涂胶的另一面朝向涂胶面的一侧施加压力，此时相接触的是，平面结构带的涂有胶水的同一面上折叠后的两侧，且两侧上均涂抹有胶水，能够直接粘固，且粘固强度比较大。
在本发明中的方法还包括以下步骤：
步骤S5：沿贴合位置裁切贴合后的平面结构带，从而形成多个包装结构。
本发明公开的制作方法中内芯层采用的衬垫带以及卷原材均采用可回收环保材料制成，经衬垫作为缓冲的内芯层，克服了现有技术中采用粉末状、颗粒状的松软结构作为缓冲材料，所造成的环境污染，空气质量差的技术问题，同时采用多层衬垫作为缓冲材料，能够达到现有的塑料板、塑胶泡作为缓冲材料的缓冲效果，保证内部物品不损坏的目的。另外，采用本发明制作包装结构时，整个原材制作，包括衬垫带的制作均是在传送带上实现，在多层贴合、折叠、粘固、裁切的过程中，传送带一直处于送给状态，生产的效率较高。
最后应当说明的是，以上实施例仅用以说明本发明的技术方案，而非对本 发明保护范围的限制，尽管参照较佳实施例对本发明作了详细地说明，本领域的普通技术人员应当理解，可以对本发明的技术方案进行修改或者等同替换，而不脱离本发明技术方案的实质和范围。

    步骤S301：设置卷原材以及衬垫带的进给位置，使所述衬垫带放卷的位置位于两卷原材放卷的原材之间；
    步骤S302：对衬垫带放卷拉伸，使衬垫带沿切割刀痕位置拉伸，形成镂空的网状衬垫卷带，并进给；
    步骤S303：向沿进给方向的衬垫的卷带的两侧边喷涂粘固胶水，并通过压合将两原材带以及衬垫卷带压紧粘固，形成平面结构带。
  9. 如权利要求8所述的全回收环保包装结构制作方法，其特征在于，所述步骤S303中喷涂的胶水为树脂胶水，压合时需要向原材带加热，以使所述树脂胶水达到粘固所需要的温度。
  10. 如权利要求9所述的全回收环保包装结构制作方法，其特征在于，所述步骤S4包括以下步骤：
    步骤S401：在平面结构带上间隔涂覆胶水，涂覆胶水的位置垂直于所述平面结构带进给方向；
    步骤S402：将平面结构带沿进给方向的中间位置折叠，使涂覆胶水的两侧彼此相对，并重合；
    步骤S403：压紧折叠后的涂胶位置。
