糖果枕式包裝機總體設計及豎封裝置設計
摘要：本課題是在目前市場上較熱門的包裝機械的基礎上，對其豎封裝置及總體結(jié)構(gòu)進行設計。該類包裝機要求傳動系統(tǒng)簡潔，工作穩(wěn)定，維修保養(yǎng)簡單，所有控制由軟件實現(xiàn)，方便功能調(diào)整和技術(shù)升級。
在傳動系統(tǒng)設計中，主要是對齒輪和軸的設計。整個系統(tǒng)的設計充分體現(xiàn)了價廉物美、簡單實用、結(jié)構(gòu)簡單，節(jié)省材料的設計原則，同時大量地使用了通用件，降低了制造成本。在豎封裝置的結(jié)構(gòu)設計中，主要采用了凸輪來控制豎封機構(gòu)的間歇運動。不但結(jié)構(gòu)簡單，而且運動也十分平穩(wěn)。控制部分采用人機界面的PLC控制，具有故障自診斷功能和參數(shù)存儲功能。而且還采用了雙變頻器控制，帶長即設即切，無須調(diào)節(jié)空走，一步到位，省時省膜。另外還用高感度光電眼色標跟蹤，數(shù)字化輸入封切位置，使封切位置更加準確。溫度獨立PID控制，更好適合各種包裝材料。
本次設計的糖果枕式包裝機功能良好，性能可靠，操作靈活方便；在結(jié)構(gòu)上，方便工廠生產(chǎn)制造以及車間內(nèi)的安裝，在使用中，便于調(diào)試和維護；同時具有生產(chǎn)成本和使用成本低等特點。

The Overall Design of the Candy Pillow Type Packaging Machine and the Design of the Vertical Encapsulation Device
Abstract: This topic is the design of the packing machine’s vertical closure device and the design of the overall structure foundation in the more popular packing machine present-market. This kind of packaging machine request succinct transmission system、stable work、the simple service maintenance and all controls realized by the software, It can adjust function and update technology.
In the design of the transmission system, main problem is the computation and examination of the gear transmission and the axis. The overall system design fully manifested the low-price and good-quality, the simple and practical principle, the simple structure, the material-saved, at the same time it has used the standard part massively, reduced the cost of production. The design of vertical closure device in the structure, mainly use the cam to control the intermittent motion of vertical closure structure. The structure not only is extreme simple, but also has steady movement. The control department adopts human-machine interface, PLC control. It has diagnosis function, and can preserve parameter. Moreover, It also uses the double – frequency changer control, when the belt has been long, it can cut following supposes, it need not to adjust and wastes time, reaches only one step to goal instantly, time-saving and material-saving. Moreover it also uses the high sensitivity electricity eye color code to track, the digitized input to the seal cut position, to make the seal cuts position more accurate. The independent PID temperature control can suit each kind of packing material better.
This device about the candy pillow type packaging machine, has good function, creditable capability, and very flexible manipulating; in its structure, it convenient plant’s production and manufacture and the workshop’s installment, in its use, it is advantageous for the debugging and the maintenance; Simultaneously the characteristic is the low cost of the production and the use and so on.
Key word: packaging machine; overall design; the design of vertical encapsulation device
