干粉混拌機(jī)設(shè)計(jì)
摘 要
隨著科學(xué)技術(shù)的發(fā)展，制造技術(shù)的進(jìn)步，以及社會(huì)對(duì)產(chǎn)品質(zhì)量和品種多樣化的要求越來越強(qiáng)烈。中、小批量生產(chǎn)的比例明顯增加，要求現(xiàn)代干粉混拌機(jī)成為一種高效、復(fù)合、集成功能和低成本的自動(dòng)化加工設(shè)備。同時(shí)，為滿足制造業(yè)向更高層次發(fā)展，為柔性制造單元、柔性制造系統(tǒng)，以及計(jì)算機(jī)集成制造系統(tǒng)提供基礎(chǔ)設(shè)備，也要求干粉混拌機(jī)向更高水平發(fā)展。
在干粉混拌機(jī)行業(yè)制造中，混拌機(jī)的效率都不是很高，尤其是大批量生產(chǎn)的時(shí)候。為了解決這類問題，現(xiàn)在采用的辦法是：設(shè)計(jì)一種雙軸的干粉混拌機(jī)，這樣一來雙軸槳葉混合機(jī)有強(qiáng)烈、高效的特點(diǎn)，而且混合時(shí)間短。臥式筒體內(nèi)兩根攪拌軸等速反向旋轉(zhuǎn)，軸上特殊角度布置的槳葉確保物料徑向、環(huán)向、軸向三向拋灑運(yùn)動(dòng)，形成復(fù)合循環(huán)，在極短的時(shí)間內(nèi)達(dá)到均勻混合。
本設(shè)計(jì)通過對(duì)干粉混拌工藝分析，確定了無重力雙軸干粉混拌機(jī)設(shè)計(jì)方案。根據(jù)設(shè)計(jì)參數(shù)，選擇了電動(dòng)機(jī)，對(duì)主要結(jié)構(gòu)進(jìn)行了詳細(xì)地設(shè)計(jì)，并對(duì)位置調(diào)節(jié)機(jī)構(gòu)、聯(lián)接機(jī)構(gòu)等也進(jìn)行了簡(jiǎn)單地設(shè)計(jì)。

Abstract
With the development of science and technology, the improvement of manufacturing technology, as well as social on product quality and variety of the increasingly strong demand. In small batch production, the proportion increased significantly, the demands of modern dry powder mixing machine becomes a kind of high efficient, complex, integrated function and low cost automatic processing equipment. At the same time, in order to satisfy the manufacturing industry to a higher level of development, as the flexible manufacturing unit, flexible manufacturing system, computer integrated manufacturing system provides the basic equipment, also called dry powder mixing machine to develop to higher level.
In the dry powder mixing machine manufacturing industry, mixing machine efficiency is not very high, especially when large batch production. In order to solve this problem, now used approach is: design a gravity biaxial powder mixing machine, thus the gravity-free twin-shaft paddle mixer with strong, high efficiency, and short mixing time. In horizontal tube the two stirring shafts isokinetic reverse rotation, axis angle arrangement to ensure that materials special blade radial, circumferential, axial three to throwing motion, to form a composite circulation, in a very short time to achieve uniform mixing.
Through the design of the dry powder mixing process analysis, identified the gravity-free twin-shaft powder mixing machine design scheme. According to the design parameters, selection of the motor, the main structure was designed in detail, and the position adjusting mechanism, coupling mechanism are simply design.
Keywords: twin-shaft paddle, dry powder mixing machine, motor
