纸托盘厂家设计纸托盘的结构需要注意什么?

来源:http://www.shuangfengbaozhuang.cn 时间:2020-06-23

纸托制品除了有纸纸托的强度和韧性之外,可以根据客户的要求制成各种复杂的形状。用作一次性快餐具时,形状比较简单,强度要求也不算高。用作工业内包装时,其形状就很复杂,它必须满足工业内包装的三大要求:
In addition to the strength and toughness of paper holder, paper holder products can be made into various complex shapes according to customers' requirements. When it is used as disposable tableware, its shape is relatively simple and its strength requirement is not high. When it is used as industrial inner packaging, its shape is very complex. It must meet the three requirements of industrial inner packaging:
一是定位要求。纸托制品必须能保证被包装物品在包装箱内有固定位置,要求纸托制品与被包装物品之间形状同步,接触贴切,尺寸准确。
First, positioning requirements. The paper support products must be able to ensure that the packed articles have a fixed position in the packing box. It is required that the shape of the paper support products and the packed articles is synchronous, the contact is close, and the size is accurate.
二是缓冲要求。纸托整体要有一定的韧性和柔性,表面还应该有些松软,与被包装物品接触摩擦时不能损伤被包装物品表面光泽,能消除包装物品在搬运中受到碰撞、振动时产生的冲击。三是承载。要求制品有一定的强度和刚性来支撑被包装物和承受外界压力。为了满足制品上述功能要求,除了选择适当的原材料、助剂和生产工艺之外,更重要的是结构设计。

Second, buffer requirements. The paper holder shall have certain toughness and flexibility as a whole, and its surface shall be soft. When it contacts with the packed goods, it shall not damage the surface luster of the packed goods, and it can eliminate the impact of collision and vibration when the packed goods are transported. Third, bearing. The products are required to have certain strength and rigidity to support the package and bear external pressure. In order to meet the above functional requirements of products, in addition to the selection of appropriate raw materials, additives and production processes, the more important is the structural design.
(1)功能性结构:
(1) Functional structure:
纸托制品成形工艺特点决定了同一个纸托只能有一个厚度,为了适应功能要求,在调整强度和缓冲性时可利用形腔和立筋,形腔可以增加制品整体的弹性和柔性,立筋可增加制品强度和刚性。在比较大的平面,承载能力要求高时,可以将此处设计成瓦楞形或蜂窝形。
The forming process characteristics of paper support products determine that the same paper support can only have one thickness. In order to meet the functional requirements, the cavity and vertical bar can be used when adjusting the strength and buffering. The cavity can increase the overall elasticity and flexibility of the products, and the vertical bar can increase the strength and rigidity of the products. In a relatively large plane with high bearing capacity requirements, it can be designed as a corrugated or honeycomb shape.
(2)工艺性结构:由于纸托模塑制品成形初期是个湿纸坯,在生产过程中,水要逐步析出,制品形状、位置和尺寸都会发生较大变化,在制品的同一个平面、同一个方向的不同位置,纸托的收缩总量不同,这时纸托就要发生翘曲或扭转变形
(2) Technological structure: since the paper holder molded product is a wet paper blank at the initial stage of forming, during the production process, water should be gradually separated out, and the shape, position and size of the product will be greatly changed. In the same plane and different positions in the same direction of the product, the total shrinkage of the paper holder is different, at this time, the paper holder will be warped or twisted
