1、外文文献专业类名称 机械设计制造及其自动化班 级 学 生 姓 名 指 导 教 师 教研室主任 年月日外文文献Comment on medicines and chemical reagents package machinery conceptuai design CommAbstract: a detailed know this paper introduces the concept of drug packaging machinery design, this packing machinery design based on certain on mathematical mode
2、ls, and also introduced the domestic and foreign drug packaging machinery and the status of in the future, through the packaging machinery in China than the deficiency of the design. Keywords: packaging machinery; Link mechanism; CAMent on medicines and chemical reagents package machinery conceptual
3、 design In recent years , Carry out GMP (medicines and chemical reagents produces specifications of quality) attestation system because of sustained our country economic situation rise and country to pharmacy industry mandatory. Medicines and chemical reagents package machinery has got quite great p

Level being close to 60%s product cannot to reach upper developed country century eighties. Large-scale advanced eq
5、uipment is dependent on entrance mainly. Low our country medicines and chemical reagents package machinery engineering level is that the design designing personnel low level from our country enterprise arouses to a great extent. One, our country medicines and chemical reagents package machinery curr
6、ent situation analyses our country medicines and chemical reagents package machinery still has bigger gap compared with advanced international level. What time is insufficient on domestic medicines and chemical reagents package machinery design under main existence1) B ackward domestic mechanical pe
7、rformance medicines and chemical reagents package machinery mostly, accuracy low velocity, is slow, stationarity dispatches package machinery travel process to contain large amount of dyadic complicated intermittence motion. Come to come true mainly from the cam, the connecting rod. But, many design

Be only the surveying and mapping carrying out a piecemeal that the abroad model machine cam connecting rod part is di

That domestic medicines and chemical reagents package machinery runs speed mostly is more general than hanging down according to cutting frequency if the aluminium moulds bubble cover packers for 100 one 300 mins, full-automa

Full-automatic medicine box packer dress box speed is able to reach 600 800 box/ mins. Not only working sp

But, advanced medicines and chemical reagents package machinery realizes supervisory control abroad mostly from computer system. Und

Adopt a single to produce a pattern first commonly. The full-automatic production line is few. Two is that full-automation works cannot to ac

If in a little paper box packer, Page, paper box all needs medicine board , specifications paper to move charging personally. And require specially-assigned person to pay attention to if specifications, medicine board, p

Other, domestic medicines and chemical reagents package mechanic failure rates are higher. Control a component (if the re

Medicines and chemical reagents package machinery is that the form designs that specifically for specially appointed package. The general specification range
