Description

组装式纸托盘
技术领域
本发明涉及一种托盘，具体地说是对现有纸托盘结构的改进。
背景技术
传统的托盘根据材料分类主要有木质托盘、塑料托盘。由于木质托盘耗费木材很大，而我国木材资源匮乏，并且为了避免虫卵滋生，因此各国规定木质托盘进口时需要薰蒸，以杀灭虫卵。鉴于上述原因，木质托盘已逐渐被淘汰。
塑料托盘由于成本高，主要用于企业内部物流周转，很少用于进出口货物运输中。
近年来，为了克服木材资源匮乏的不足，一些制造商设计出纸托盘，以替代木质托盘。但现有纸托盘存在着强度低的缺陷，承重有限，使用范围受到限制。
更为重要的是，上述三种托盘存在着一个共同的缺陷，就是托盘必须制成固定框架式，不能制成散件，到用户处再进行组装。例如木托盘的横梁和纵梁之间是由钉子连接固定；塑料托盘是整体注塑式；而纸托盘的各部件也是由钉子和胶水粘接成一整体。这就造成托盘体积大，占据空间，运输困难，运输成本高。由于该缺陷，进而造成托盘制造商的供货范围受到了限制，无法远程供货，只能在近距离范围内供货。
发明内容
本发明提供了一种组装式纸托盘，它可以解决固定式托盘存在的体积大，运输困难和运输成本高等问题。
为了达到解决上述技术问题的目的，本发明的技术方案是，一种组装式纸托盘，其特征在于托盘的组装件包括纸槽和装在纸槽中的纸板芯，纸槽形状似U形状，在纸槽、纸板芯连接部位预留有膨胀螺丝孔。
在本发明中，还具有以下技术特征，纸槽包括宽浅纸槽和深窄纸槽。
在本发明中，还具有以下技术特征，还包括异形深窄纸槽，异形深窄纸槽的一侧面比另一侧面高，高侧面为倒L形。
在本发明中，还具有以下技术特征，两宽浅纸槽上下扣装内装有纸板芯构成一个横撑；两个深窄纸槽上下对装内装有纸板芯构成一个立撑；或一个深窄纸槽与一个异形深窄纸槽上下对装内装有纸板芯构成一个边立撑，上述纸板芯以直面方向装在纸槽中，通过上述横撑与立撑或边立撑间隔排列，横撑在上立撑或边立撑在下，通过向预留的膨胀螺丝孔装入膨胀螺丝固定上述横撑与立撑或边立撑，从而组装成托盘。
在本发明中，还具有以下技术特征，组装时，多个横撑与多个立撑间隔排列，横撑与立撑垂直安装，立撑中的下深窄纸槽和装在其内的纸板芯安装在横撑下面，立撑中的上深窄纸槽一部分安装在横撑上面；立撑中的上深窄纸槽另一部分安装在横撑与立撑形成的空腔内，上深窄纸槽与横撑上面接触部分的槽壁预先裁切掉，下深窄纸槽中的纸板芯为城墙形，高出部分装在横撑与立撑形成的空腔内，低矮部分装在横撑下面，横撑、立撑以及纸板芯通过向预留的膨胀螺丝孔内装入膨胀螺丝连接固定，从而组装成托盘。
在本发明中，还具有以下技术特征，两宽浅纸槽上下扣装内装有纸板芯构成一个横撑；两个深窄纸槽上下对装内装有纸板芯构成一个中间立撑，一个深窄纸槽与一个异形深窄纸槽上下对装内装有纸板芯构成一个边立撑，上述纸板芯以直面方向装在纸槽中，组装时，多个横撑与多个中间立撑和两个边立撑间隔排列，横撑与立撑垂直安装，上述中间立撑的下深窄纸槽、边立撑的异形深窄纸槽和装在其内的纸板芯安装在横撑下面，上述中间立撑、边立撑中的上深窄纸槽一部分安装在横撑上面；另一部分安装在横撑与立撑形成的空腔内，上深窄纸槽与横撑上面接触部分的槽壁预先裁切掉，下深窄纸槽中的纸板芯为城墙形，高出部分装在横撑与立撑形成的空腔内，低矮部分装在横撑下面，横撑、中间立撑、边立撑以及纸板芯通过向预留的膨胀螺丝孔内装入膨胀螺丝连接固定，边立撑的高侧面顶部侧壁与横撑底面之间用膨胀螺丝连接固定，从而组装成托盘。
在本发明中，还具有以下技术特征，一个立撑中相对装的上、下深窄纸槽之间留有间隙。
在本发明中，还具有以下技术特征，所述纸板芯是由多层纸板叠合而成，纸板是平纸板、瓦楞纸板或蜂窝纸板。
在本发明中，还具有以下技术特征，所述宽浅纸槽、深窄纸槽或异形深窄纸槽的槽壁是由多层纸，通过粘接剂粘接制成，所用纸为牛皮纸、包装纸。
在本发明中，还具有以下技术特征，宽浅纸槽、深窄纸槽或异形深窄纸槽的槽壁所用粘接剂用内含瓷粉的黏合剂。
本发明与现有技术相比具有以下优点和积极效果：1.托盘由组装件构成，因而托盘不必预先成型，用户可以根据组装说明现场自行组装，散装的组装件体积大为缩小，易于运输，降低了运输成本。2.U型纸槽的槽壁由多层牛皮纸粘接制成，纸槽强度高，抗磨损，纸槽内装有纸板芯，进而形成抗压整体，经实验表明，抗压强度至少可达到5吨以上，满足各种包装箱承载的要求。3.组装件仅由U型纸槽、纸板芯和膨胀螺丝组成，结构简单，易于制造，组装过程简单，技术和操作能力要求低。4.托盘由纸制成，免薰蒸，无污染，可回收利用，节约木材。5.回收时，只需将膨胀螺丝用工具取出，各U型纸槽、纸板芯就成散件，回收工艺简单，时间短，效率高。

具体实施方式
参见图3，这是组装件中的宽浅纸槽2-1，壁厚为8mm、纸槽宽度为86mm、总宽度为100mm、槽的高度为24mm，总高度为32mm，纸槽长度可根据用户要求确定。制造时，用400G原纸经分纸机加工成规定幅宽的U型纸板主料，再用护角机加工成8mm厚U型纸板，要求黏接剂内含瓷粉，以保证纸板硬度。
宽浅纸槽2-1用来制成横撑2。组装时，两宽浅纸槽2-1上下扣合，内装有纸板芯4，纸板芯4以直面方向装入槽中，因而形成一个横撑2。
参见图4，这是组装件中的纸板芯4，主要起承载作用。高克重原纸经五层瓦楞纸板生产线加工成瓦楞纸板，5层瓦楞纸板经模切机加工成特定形状纸板，一定数量的特定形状纸板经粘合、压力机加压制成纸板芯4。纸板芯4的厚度与装入其内的宽浅纸槽2-1或深窄纸槽3-1、3-2的槽宽相适配，这主要根据托盘1的承重确定。
在立撑3中的纸板芯4为城墙形，一高一低，高出部分4-1装在横撑2与立撑3形成的空腔7内，低矮部分4-2装在横撑2下面；在横撑2中的同一纸板芯4的高度相同，如图1和图2所示。
参见图5，这是组装件中的深窄纸槽3-1、3-2，壁厚为8mm、纸槽宽度为44mm、总宽度为60mm，槽的高度为62mm，总高度为70mm，纸槽长度可根据用户要求确定。
在制造过程中，上深窄纸槽3-1与横撑2上面接触部分的槽壁已经预先裁切掉，为了安装时相适配。
深窄纸槽3-1、3-2的制造过程与宽浅纸槽2-1相同。
上、下深窄纸槽3-1、3-2对装，内装有纸板芯4，纸板芯4以直面方向装入槽中，因而就形成一个立撑3。
参见图6，这是异形深窄纸槽3-3，主要用于边立撑3″的下部的纸槽。异形深窄纸槽3-3的一侧面比另一侧面高，高侧面3-3-1为倒L形，通过高侧面3-3-1顶部侧壁抵靠在横撑2底面，然后用膨胀螺丝5连接固定，从而加强边立撑3``区域的强度。
可以将上述组装件预制成型后，以散件形式运输至用户处。
实施例1，参见图1，组装时，托盘1的形状、规格大小、排列方式等根据包装箱的大小、重量等因素进行确定。
在本实施例1中，组装时，5个横撑2与4个立撑3间隔排列，横撑2与立撑3垂直安装，立撑3中的下深窄纸槽3-2和装在其内的纸板芯4安装在横撑2下面，立撑3中的上深窄纸槽3-1一部分安装在横撑2上面；立撑3中的上深窄纸槽3-1另一部分安装在横撑2与立撑3形成的空腔7内，上深窄纸槽3-1与横撑2上面接触部分的槽壁已经预先裁切掉，下深窄纸槽3-2中的纸板芯4为城墙形，高出部分4-1装在横撑2与立撑3形成的空腔7内，低矮部分4-2装在横撑2下面，横撑2、立撑3以及纸板芯4通过向预留的膨胀螺丝孔6内装入膨胀螺丝5连接固定，从而组装成托盘1。
一个立撑3中相对装的上、下深窄纸槽3-1、3-2之间留有间隙，这样可以在受压时，上深窄纸槽3-1被下压，留有一定的变形伸缩量。
膨胀螺丝5采用塑料制成，固定时，可以涂抹胶水，以增加结合的牢固度。
同样，在横撑2与立撑3结合面中的一部分涂抹粘接剂，以增强结合的牢固度。
上述组装件，如宽浅纸槽2-1、深窄纸槽3-1、3-2和纸板芯4的尺寸关系，可以根据不同的要求进行改变。
通过上述结构可以看出，横撑2和立撑3横纵结合，宽浅纸槽2-1、深窄纸槽3-1、3-2自身的强度，加之槽内的纸板芯4以直面方向装入，共同形成一整体，其承压强度大为提高，经实验表明，抗压强度达5吨以上。
托盘1的形状不限于上述结构，可以根据用户和包装箱等要求进行确定。
实施例2，参见图2，与实施例1的区别是，两边立撑3``的下纸槽采用图6中的异形深窄纸槽3-3，异形深窄纸槽3-3内侧面比外侧面高，高侧面3-3-1为倒L形，通过高出部分的顶部侧面与横撑2下底面接触起到支撑作用，并且膨胀螺栓固定，这样可以增加抗压强度，提高托盘整体强度。
以上所述，仅是本发明的较佳实施例而已，并非是对本发明作其它形式的限制，任何熟悉本专业的技术人员可能利用上述揭示的技术内容加以变更或改型为等同变化的等效实施例。但是凡是未脱离本发明技术方案内容，依据本发明的技术实质对以上实施例所作的任何简单修改、等同变化与改型，仍属于本发明技术方案的保护范围。
