Description

Vacuum packaging equipment

Technical field

The utility model relates to a kind of vacuum packaging equipment, particularly relates to a kind of vacuum packaging equipment that is used for main equipment and lot item sealing preservation.

Background technology

The vacuum preservation technology also claims vacuum-packed technique, originates from the forties in 20th century, and after polyester, vinyon were successfully applied to commodity packaging from nineteen fifty, vacuum-packed technique had just obtained development rapidly.Vacuum-packed technique mainly is that equipment or the article that will be sealed up for safekeeping place under the vacuum-packed condition; the packaging bag in-to-in major part of promptly finding time air; make it to produce certain degree of vacuum; the surface that allows cover be adjacent to be sealed up for safekeeping thing; again in conjunction with putting into oxygen absorbent and desiccant; reduce the existence of oxygen and moisture, make equipment surface or article surface and air isolated, thereby reach the purpose of preventive device or article.Vacuum-packed technique has been widely used in numerous areas such as light industry, food, medicine, chemical industry, military project, precision instrument manufacturing, metal work as a kind of gas phase preservation and packaging technology.And the higher automation vacuum packing machine of degree of automation has appearred.

But above-mentioned vacuum packing machine is applied to the packing of midget plant or article mostly at present, and the sealing preservation that vacuum-packed technique is applied to main equipment and lot item has run into bigger obstacle.

Along with The development in society and economy, more and more countries office, enterprises and institutions and individual have main equipments such as vehicle, vehicle for construction, construction machinery and equipment; Vast rural area also has increasing large-scale agricultural machinery equipment such as trac., rice transplanter, reaper etc.; Numerous car production producers and other main equipment manufacturers finish its manufacturing and the products such as automobile do not sold as yet also have the needs of appropriate preservation; Numerous business units comprises that pharmaceutical producing enterprise, grain processing enterprise etc. have some valuable large raws MAT'L (as rare traditional Chinese medicine and high-quality agricultural byproducts raw material) needs and properly preserve; Along with the quickening of China force modernization paces, increasing all kinds of main equipments are equipped my army, join PLA's all departments such as logistics military supplies, ordnance support.Comparatively speaking, the value ratio of above-mentioned main equipment and lot item is expensive, if do not prepare then during this period of time generally it to be kept in the storehouse its use in a long time.But because the restriction of current conditions such as funds shortage, soil are rare, storehouse anxiety, the maintenance condition separately of these equipment and article differs widely, and has only small part unit or individual to build enough permanent storehouses and is used to deposit its main equipment and lot item.A large amount of main equipments can only be parked in the open, no matter the wind and weather Exposure to Sunlight, cause equipment corrosion, paint film in various degree to fade aging easily and etc. phenomenon; What a large amount of lot items had also can only park in the open, and what have just preserves in simple and easy storehouse, causes in various degree deterioration of article, phenomenon such as rotten easily.In addition, find by investigation, even some main equipments and lot item have had special-purpose storehouse, but the condition of storehouse may not meet preservation condition, still need personnel that it is safeguarded, the daily attention task is quite heavy, and the air humidity of storehouse and temperature also are difficult to be controlled under the desirable condition.We can say, build the costly of special-purpose storehouse large-scale, that meet preservation condition.

For main equipment, it is to be that main body has rubber, lubricating oil, fuel oil, plastics and electronic machine etc. concurrently with the metal mostly, the principal mode that metal is corroded is an atmosphere corrosion, its dominant mechanism of getting rusty is because the variation of temperature, relative humidity in the air makes the metal surface that chemical change take place.The ageing-resistant degree of annexes such as rubber plastic electronic machine and the oxygen in temperature humidity and the atmosphere also have substantial connection.Therefore, the variation of the oxygen of air and temperature thereof, relative humidity is the principal element that causes the main equipment parts aging.

For the particularly large valuable raw MAT'L of lot item, the variation of the oxygen of air and temperature thereof, relative humidity is to cause raw MAT'L deterioration, rotten major cause, and the damaged by rats of damaging by worms also is a major reason of material damage.Common storehouse can't be accomplished its appropriate preservation, as desire appropriate preservation, the large-scale special air conditioner storehouse that the needs construction is costly.

Yet, contrast these above-mentioned main equipments and large item the preservation environment, preserve requirement, operating needs and environment for use, its sealing is preserved and is had very big problem really.For cost consideration, unit that has or individual take the way to its main equipment or large material air storage; The common simple and easy storehouse that utilizes that has is preserved the way of stacking; What have has taked local method of seal to equipment, add a protecting jacket in the part of equipment, as positions such as automotive windshield, headlight, tire are added protective cover etc., the erosion of local wind and weather and sand and dust has just been protected in these measures, can not guarantee parts not by the erosion of Exposure to Sunlight, air oxidation and salt fog, and complex operation; The department that has has adopted antivacuum whole method of seal to vehicle, but this type of antivacuum integral body seal up for safekeeping technology to seal effect up for safekeeping general, it is oversize to seal operating time and unpacking operating time up for safekeeping, needs manually to mend maintenances such as envelope, inflation between preservation life.

Certainly, also have some units that its important main equipment has been taked the vacuum-packed method of seal of single-piece, and present overall vacuum packing seal up for safekeeping mode closing device adopted is high frequency heat seal technology or pressure-sealing zipper technology.

Though closing device adopts the vacuum packaging equipment price of high frequency heat seal technology more cheap, but be subjected to the restriction of materials used, environment and condition more, be suitable for disposable sealing up for safekeeping to the less parts of volume, it generally is disposable use, in case unpacking then can not repeated usage, and the operability of sealing up for safekeeping is bad.

Though closing device adopts the vacuum packaging equipment of pressure-sealing zipper technology easy for operation and can repeated usage, but reusable number of times is limited, its maximum defective is than higher to the requirement of preserving environment and environment for use, be that weather resisteant is relatively poor, and price is expensive, cost is high, and economy is bad.
