【摘要】：蜂窩紙板作為一種新型的包裝材料,被廣泛應用于各類產(chǎn)品的運輸、包裝和其它領域。蜂窩紙板在實際出廠前要進行護棱和護角處理(稱為包邊),用來消除在搬運、入庫和運輸過程中對物品邊緣或角部的損傷,以及提高紙板的表面強度,還具有一定的防潮和阻燃功能。傳統(tǒng)的護棱和護角處理是用護棱、護角紙通過手工操作進行包邊,本文稱這種包邊方式為“有源包邊”。由于企業(yè)所生產(chǎn)的蜂窩紙板尺寸規(guī)格不一,“有源包邊”所需的護棱、護角紙也需要各種不同規(guī)格,并且在包邊過程中需要兩個熟練工進行操作,所以傳統(tǒng)的“有源包邊”不僅生產(chǎn)效率低,包邊質量參差不齊,而且生產(chǎn)成本也相對較高。本文首先對蜂窩紙板力學性能做了詳細的研究,給出了蜂窩紙板的本構方程,并根據(jù)其受力具有明顯的方向性設計一種不需要額外護棱、護角紙的自動化蜂窩紙板包邊機,本文稱“無源型”蜂窩紙板包邊機。該包邊機采用“無源包邊”方式,是利用紙板通過壓芯后的板面自身余量進行包邊,不僅不需要各種規(guī)格護棱、護角紙,還大大節(jié)省了包邊生產(chǎn)成本。為了克服了蜂窩紙板因內部應力而造成的板面不平整問題,使壓芯成型裝置能夠隨著蜂窩紙板棱邊對其進行“壓芯”處理,并能將余出的上下表皮粘合在紙板棱邊上進行包邊,本項目擬在該自動化包邊機中使用柔性隨動系統(tǒng)。使用柔性隨動系統(tǒng),可以提高了整個裝置的穩(wěn)定性和產(chǎn)品的成品率,自動化的生產(chǎn)方式也提高了生產(chǎn)效率,具有巨大的經(jīng)濟效益和廣闊的市場。最后使用ANSYS有限元分析軟件模擬蜂窩紙板靜壓試驗狀態(tài),分析紙板在受壓時一些特性,并基于Solidworks Simulation對傳送輥輪做了疲勞分析,驗證了該蜂窩紙板包邊機傳送設計的可行性。同時還對初代工程機包邊生產(chǎn)中出現(xiàn)的主要問題進行了詳細的分析,初步得出了這些問題出現(xiàn)的原因,并結合實際生產(chǎn)提出相應的改進方案,計劃在下一代設備中得到解決。
[Abstract]:As a new packaging material, honeycomb board is widely used in transportation, packaging and other fields of various products. It is used to eliminate the damage to the edges or corners of articles in the course of handling, storage and transportation, and to improve the surface strength of paperboard. It also has certain moisture-proof and flame-retardant functions. The beehive paper is wrapped by manual operation, which is called "active edge wrapping" in this paper. Because the size of honeycomb paperboard produced by the enterprise is different, the "active wrapping edge" needs to protect the edge. Corner paper also needs a variety of specifications, and in the process of edge wrapping needs two skilled workers to operate, so the traditional "active edge wrapping" not only low production efficiency, edge quality is uneven. And the production cost is relatively high. Firstly, the mechanical properties of honeycomb paperboard are studied in detail, and the constitutive equation of honeycomb paperboard is given. And according to its force has obvious directivity to design an automatic beehive paperboard wrapping machine without extra protecting edge and angle protecting paper. This paper describes a "passive" honeycomb paperboard wrapping machine, which adopts the "passive edge wrapping" method, which uses cardboard to wrap the edge through the allowance of the board after pressing the core, and not only does not need all kinds of specifications to protect the edges and corner paper. In order to overcome the unevenness problem caused by internal stress of honeycomb paperboard, the core pressing device can "press core" with the edge of honeycomb paperboard. And the remaining upper and lower epidermis can be bonded on the edge of the cardboard to wrap the edge. This project intends to use the flexible servo system in the automatic border-wrapping machine and use the flexible follow-up system. It can improve the stability of the whole device and the finished product rate of the product, and the automatic production mode can also improve the production efficiency. At last, ANSYS finite element analysis software is used to simulate the static pressure test state of honeycomb paperboard, and some characteristics of paperboard under compression are analyzed. The fatigue analysis of transfer roller based on Solidworks Simulation is carried out. The feasibility of the transmission design of the beehive paperboard wrapping machine is verified. At the same time, the main problems in the initial generation engineering machine are analyzed in detail, and the reasons for these problems are preliminarily obtained. According to the actual production, the corresponding improvement scheme is put forward, and it is planned to be solved in the next generation equipment.
