At present, our country has become the world packing mechanical industrial production and expends one of great nations. Current our countr
17、y food and a packing machinery prominent question is the new product development cycle long, imitates much, innovates few, not only this with designs personnels state-of-art related, also concerns with the correlation profession development. The international advanced method utilizes the simulation
18、technology, by the computer automatic synthesis three-dimensional model, will pass has occurred production line breakdown data feeds the computer, then will demonstrate the actual operating mode, according to will need to carry on the revision in front of the user, finally will consummate. The packi
19、ng machinery took one product, its meaning is not merely the product itself material significance, but is includes the form product, the stealth product and extends the product 3 meanings. The form product is refers to packaging machine itself the concrete shape and the basic function; The stealth p
20、roduct is refers to the packaging machine the actual utility which provides to the user; Extends the product is refers to the packaging machine the quality assurance, the use instruction and the post-sale service and so on. Therefore the packaging machine design should include: Market investigation
21、and study, schematic diagram design, structural design, construction drawing design,instruction for use compilation and post-sale service predetermined plan and so on. “十五” period, our country packs the mechanical industrial development to be rapid, in recent years imports the equipment all is domes
22、tic cannot make or the manufacture level is far from, may see our disparity from the import to be at. Food security problem whole nation attention. “十一五” period should enhance food security domain the science and technology and the equipment level, the development fast, in accurate appraisal food ha
23、rms the factor the technology and the equipment, further researches and develops the pathogenic microorganism resistance, cause of disease prevention technologies and the preserve technology and the equipment and so on control. Food and the packing machinery form the profession already for 20 years,
24、 is opposite in food packing, a new profession. This 20 years also are the world technological development quickest times, the new technology applies unceasingly in the profession, but the domestic profession foundation is weak, technical and the scientific research lack of strength, its development
25、 relative lag, has towed food and the packing industry hind leg to a certain extent. Although overall development quick, but food packing mechanical industrial development is quicker. the goal is must reduce this space, catches up with the world advanced level for the food industry, for causes the p
26、acking great nation to make great strides forward to the packing powerful nation, provides the advanced technical equip, lets import the equipment the role which only plays in the domestic market appropriates lost articles fills a vacancy. This request domestic food and the packing machinery year de
27、velopment speed surpasses 18%, the new product output value rate achieves 25%. On the international packing and food machinery development is take the big customer request as the goal, the impetus correlation machinery development. The big customer request mainly manifests in the below aspect: One,
28、is higher well to the production efficiency request. This may reduce the product the cost, satisfies the date of delivery. The high speed packaging machine request must have the correlation engagement with the first working procedure, does not have to transport the link, including the control engage
29、ment, the entire production line must achieve the inverted order according to the production and the packing working procedure arrangement to start, smooth engine off. If Leng Guanzhuang the production line makes something a matter of political line automatically from the plastic raw material to the
30、 drink fills installs, the big packing piles buttress completely automatically in seals up in the workshop to carry on. Two, may adapt the product renewal change. The packing machinery must have the very high flexibility and the flexibility, the production line permission the packing material size m
31、ay change in certain size scope. Because product life cycle far short in useful life of equipment, change product and packing not as for replacement expensive packing production line. Three is the equipment common breakdown rapid elimination. The solution inputs the computer in advance, when the equ
32、ipment appears the common breakdown may diagnose voluntarily, also may implement the long-distance diagnosis to eliminate the breakdown abreast in row. Four, the request has the automatic diagnosis function. On the one hand may automatic diagnosis packing material thickness, degree of hardness, the
33、counter-tension and so on, feed back through the computer to the manipulator adjusts the movement scope, does not guarantee the resilience. On the other hand, each different product, like shape each different chocolate or the dessert and so on, install to the identical box in, its arrangement is ord
34、erly. The production line transmits the product is a disorder,the available probe head scanning, determined the different shape the material position,feeds back again to the different manipulator, it can accurately unmistakably puts in the goods according to the accurate position and the direction i
35、n the tray, moreover, removes the manual control quickly the vision and finger weariness. Five, may reduce the environmental pollution as far as possible. The reduction including the noise, the dust pollution, and reduces the reject as far as possible, this point especially is important in the food
36、processing process. Food raw material when processing not only harvests the main product, like corn processing, product besides corn starch, but also has the corn oil, the salad oil, the margarine, the glucose, the corn protein and the feed, as well as the sewage treatment and so on produces the ent
37、ire process, is the automation. Does not have the reject, not to pollute, other product value has surpassed the corn starch greatly the value. Along with the science and technology development and the market competition aggravating, the customer demand more and more is also high. This kind of demand
38、 manifests in following several aspects: One, enhances the production efficiency, satisfies the date of delivery and reduces the production cost the need, to some products, but also requests the packing machinery and the production machinery links up; Two, is meets the product renewal change need, t
39、he packing machinery must have the high flexibility and the flexibility; Three is when the equipment appears the breakdown, the request can carry on the long-distance diagnosis service;Four, favors the environmental protection, the noise, the dust and the reject are few; Five is the equipment purcha
40、se investment are as far as possible few, the price must be as far as possible low. Therefore, must certainly in the market investigation and study foundation, the full understanding, analyze the user earnestly the demand, the definite packaging machine should complete the function and each technica
41、l specification, draw up the preliminary principle design proposal.The modern packaging machine design process should include: The market investigation and study, the user demand analysis, the packaging machine function determination, the feasible proof, the formulation design proposal, the user ben
42、efit analysis, the plan feasible proof, the schematic diagram design, the structural design, the construction drawing design, the prototypical manufacture (hypothesized manufacture), the technical confirmation and the construction drawing revise, the formulation post-sale service predetermined plan
43、and the long-distance diagnosis plan, the improvement design, the serialized design and so on. The market investigation and study is the foundation work which all packaging machines design. Without the market investigation and study, we do all design work all possibly is equal to the zero. The marke
44、t investigation and study, may according to the policy guidance, the profession supply and demand information, the expert analyze, the profession unfolds clues and so on meeting, technical meeting, found the user the demand information, after and reorganizes the analysis, the definite packaging mach
45、ine should complete function. In the principle project design process, first must understand fully the related information product, the electronic products function, understood the air operated part the performance, and uses to simplify the mechanical drive system, but also may use the multi-electri
46、cal machinery dragging to reduce the mechanical transmission chain. Regarding the essential mechanical drive system, should make the best the modernized design method, in to product functional analysis foundation in, through innovation idea, system modelling, mechanical analysis, dynamic optimizatio
47、n, thus obtains the best design proposal. The technical design is the principle design structurization, definite spare part quantity, the shape, the size, the material and so on, the essential components carry on the power computation, the power computation, the strength calculation, the rigidity co
48、mputation to the major component in. When system design, must consider the entire packaging machine system comprehensively the layout, the movement coordination, the modelling design, the human - machine environment as well as the packing transportation and so on. The modular design is one advanced
49、design method, its core thought is divides into systematically according to the function certain modules,the identical function unit designs the packaging machine in has the module which the different performance, may exchange, through the module different combination, causes the packaging machine multi-purpose, the seriation. Uses this method the merit is: (1) makes the packaging machine renewal speed to speed up. Because of the new type substitution, often is the partial improvement. The vanguard technology introduction corresponding module, compared with easy to realize th
