1、Comment on medicines and chemical reagents package machinery conceptual designIn 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. Me
2、dicines and chemical reagents package machinery has got quite great progress. The new product increases by gradually. Engineering level has had very big improvement. But be returning very big gaps back to existence compared with international standards. Level being close to 60%s product cannot to re
3、ach upper developed country century eighties. Large-scale advanced equipment 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
4、, our country medicines and chemical reagents package machinery current situation analysesOur 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 machi
5、nery design under main existence1) Backward domestic mechanical performance 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 c
6、ome true mainly from the cam, the connecting rod. But, many design that the personnel is unable to require that the independence designs the parameter calculating cam bar linkage kinematics and dynamics according to job cycle picture and accuracy. Be only the surveying and mapping carrying out a pie
7、cemeal that the abroad model machine cam connecting rod part is dismantled down simplely. Bring about actuating mechanism error is very big. That domestic medicines and chemical reagents package machinery runs speed mostly is more general than hanging down according to cutting frequency if the alumi
8、nium moulds bubble cover packers for 100 one 300 mins, full-automatic medicine box packer dress box speed 50- 200 boxes/ ms in. But, on the international, the advanced aluminium moulds rushing steeping cover packer cutting frequency be able to reach 600 mins. Full-automatic medicine box packer dress
9、 box speed is able to reach 600 800 box/ mins. Not only working speed of domestic medicines and chemical reagents package machinery is slow. And, the partner has bigger noise.2) Is under the control of horizontal backward. Domestic medicines and chemical reagents package machinery controls low, auto
10、mation of level difference mostly , the malfunction leads height. (Main package machinery finger box dress controls domestic medicines and chemical reagents with drinking wine holding machinery with) adopt PLC to do a scene mostly. But, advanced medicines and chemical reagents package machinery real
11、izes supervisory control abroad mostly from computer system. Under the control of horizontal relatively backward. Great majority domestic medicines and chemical reagents package machinery automation sex is relatively poor. Adopt a single to produce a pattern first commonly. The full-automatic produc
12、tion line is few. Two is that full-automation works cannot to achieve. Require that the manpower feeds in raw material. Hand movement enchases. If in a little paper box packer, Page, paper box all needs medicine board , specifications paper to move charging personally. And require specially-assigned
13、 person to pay attention to if specifications, medicine board, paper box already finish using at any time. Happen to avoid bringing about machine racing or bringing about incomplete specifications, medicine board, and medicine box phenomenon. Other, domestic medicines and chemical reagents package m
14、echanic failure rates are higher. Control a component (if the relay, electromagnetic valve, contactor, breaker etc.) etc. are often easy to damage. Halt also to frequently occur the malfunction.3) Functions are unitary, expansion sex is bad. Medicines and chemical reagents package machinery is that
15、the form designs that specifically for specially appointed package. The general specification range inner in regulation is adjustable. But, a lot of our country medicines and chemical reagents package machinery considers insufficiency when designing that. Be not that reforming going a step further s
16、ets apart sufficient space. Cause the machinery designing that to be able to only adapt to the form board in several kinds simplicities. Change not adapting to wrapping material or the form board dimension. Fit in with even. The package finished product mass giving birth to a child is neither nice.4) Considers deficiency synthetically. Resource does not fully utilize. Our country medicines and chemical reagents there exists the chaos phenomenon in package machinery design
