花卉包裝機(jī)設(shè)計(jì)——花卉傳輸部分的設(shè)計(jì),花卉,裝機(jī),設(shè)計(jì),傳輸,部分 Fundamentals of Mechanical Design The present situation of packaging machinery in China: The packaging of the product is an important part of China's industrial development, and it is an indispensable emerging industry in the national economy. China's packaging machinery has a low starting point. Because of the different nature of the enterprise, there is a difference between the money and equipment between enterprises, and the level of automation is not consistent, and most companies are on the low level equipment. Twenty years ago, the first time that the packaging machine was applied to the packaging machine was the first time that a PLC was applied to the packaging machine automation technology. Then, as control and drive technology, servo technology and digital ideas stepped in, the packaging machine market had undergone many changes. At present China has become the world's largest commodity producer and exporter, global attention has focused on the fastest growing and largest, the most promising Chinese packaging market. After more than 20 years of development, the packaging machinery of China has become one of the ten industries in the machinery industry, which provides an effective guarantee for the rapid development of packaging industry in China. But at present, China's packaging machinery exports are less than 5 percent of the total output value, but the import amount is quite the same as the total output value, far from the developed countries. There is a shortage of leading enterprises in the packaging machinery industry, and there are not many enterprises with large scale and high quality products. According to the food and packaging machinery industry association, China now has more than 3,600 packaged-machinery manufacturers, but only 20 are now worth more than 100 million yuan. The rapid development of packaging products in our country needs to drive the whole of the vigorous development of packaging industry, including packaging machinery enterprises are also facing a very good development opportunities, but there are many factors restrict the development of packaging machinery industry. The problem of automatic packaging machine automation in China: The automatic packaging machine of China is still basically in the test imitation stage, the self-development ability is weak, lack the scientific research production the test base. Statistics show that more than 1300 kinds of varieties of packaging machinery in our country only, supporting small, lack of high precision and large scale production, product can't meet the demand of market, product quality gap in the product performance is low, poor stability and reliability, not beautiful appearance style, rough surface treatment, poor quality of many components, short service life, low reliability, affect the quality of the whole product. Despite the wide prospect of market, such as low-level enterprise on a smaller scale, product and poor reliability, import dependence, serious, inadequate development ability is low, research and development, lack of professional and technical personnel and also make the domestic packaging machinery products to ridicule. 1, according to the enterprise on a smaller scale, packing industry is developing rapidly in China, so far the national packaging machinery production of 533000 sets of production value of 130 billion yuan. There are more than 9000 packing machinery enterprises, more than 550,000 employees, more than 130 scientific research institutes and colleges and universities, over 1, 300 varieties of products. The packaging enterprises are many, the output is much, the product structure is fragmented and becomes one of the important factors that restrict the development of the packaging machinery industry in China. There are serious duplication problems in the packaging machinery industry, and low barriers to entry and inadequate regulation are the main causes of this problem. Because of low starting point, packaging machinery enterprises "deficiency" and across departments, overall planning, macro guidance difficult problems, in terms of investment and development of new products is often a coax, low level repeated disorderly competition. 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 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 reach 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, our country medicines and chemical reagents package machinery current 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 existence 1) 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 come 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 piecemeal 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 aluminium moulds bubble cover packer's 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 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, automation 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 realizes 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 production 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 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 mechanic 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 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 sets 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. A lot of machinery designs that the personnel drags to the electric motor moving the synchrony technology, the servo drive technology do not knows. The problem simple electrical equipment available is resolved uses complicated mechanism to come to come true but. Some though the control organ works to come having adopt the synchrony electric motor to wait for a device. But choose block of wood ding-dang. The maximum having brought about resource not only wastes this condition. And make machinery function designing that low. 5) System under the control of schemes design. In medicines and chemical reagents package machinery, a very important part is that real time detecting is back-off to every organization. To ensure that equipment operation is smooth. Now many machinery products has selected and used large amount of photo electricity switch being the detecting component. Equipment has such as PC detecting bubble cover system on some machinery and the like system. This need all designs that meticulously. And, the general naval company is an integral whole. Three, concluding remarks The thought a concept is designed melts to enter medicines and chemical reagents package machinery design being able to fall off designing a fault. Shorten a design cycle. Accelerate the product exploitation. Make the product designing that more rational, have affinity, more suitable man-machine project more. It is also that the main means costing down and improving enterprise competition is short of passive competition aspect backward for improving medicines and chemical reagents package machinery design at the same time. To adapt to the challenge that "queen GMP times" brings about. Design that the personnel must take product conceptual design seriously. Deepen the significance understanding conceptual design's.
