The Classification of vacuum capping machine technology and comparison with each other

The existing technology to realize vacuum capping machine model is mainly divided into three kinds: the steam jet, semi-sealed vacuum-sealed vacuum type.The steam jet strictly speaking without vacuum chamber, instead of using the steam tunnel is equivalent to the exhaust box exhaust cover fastening and rub Capping semi-hermetic vacuum type seal at the top of the machine at the same time in the short exhaust processthe ring drops nip forming vacuum chamber in the bottle shoulder, As part of the composition of the vacuum chamber bottles, called semi-sealed vacuum chamber, the reference "twist cap vacuum sealing machine (JB/T10642-2006). Hermetically sealed vacuum formula is on the machine provided with the structure of the vacuum chamber can be fully formed, the bottle is completely placed in a vacuum chamber with lid capping vacuum.

These three forms have their own characteristics: first steam jet with high productivity advantages, but the existence of the lack of energy consumption,the need to inject a lot of steam to the steam tunnel, steam consumption of about 250 kilograms per hour, and the actual steam utilization rate is extremely low,The leakage of steam may also influence workshop environment, into the bottle of steam liquefied will affect the product quality, and the second line is commonly used belt structure scrubbing ,can not ensure the stress of the agreement every bottle and caps ,they will cause the fracturing breakage of the bottle and the cap buckle damaged or not screwed in place, and can achieve a degree of vacuum is equivalent to the effect of the exhaust box, and also there is the impact of the high temperature of the steam quality of content itemsfactor.At present the main application in canned fruit production line more.The type model of half seal vacuum chamber is due to the formation of the vacuum chamber movement range relatively small, the vacuum chamber was less invalid gap, so the form of the semi-sealed vacuum chamber capping machine capacity must be high relative to the entire seal can be achieved of 40 bottles per minute, But for body bottle shoulder shape error,bottle shoulder smaller or Bottle mouth diameter greater than body bottle,and type of round bottle , this kind of use body to form part of the vacuum chamber is powerless the way. In addition, the semi-sealed models can not be achieved automatically with cover, in the engaging state of the cap semi vacuum require a larger vacuum apparatus and can not guarantee that each bottle can be evacuated.From the transmission structure of speaking, it can achieve 40 CPM productivity situation the action of machine parts pass the hard links through mechanical transmission, intermittent dial out of the bottle, the vacuum hood moves up and down, as well as the driving force of the capping institutions can not be set in terms of the transmission structure,Once the encounter card bottle, the bottle must fragmentation resulting in the loss of materials and efficiency.All seal vacuum chamber forms of glass vacuum capping machine in the spark out before X30 series at home and abroad are rare, with current electrical control technology and high-performance electrical components programming control in order to achieve straight-sealed vacuum chamber Spark proprietary driver, hermetically sealed vacuum chamber model is a cylindrical space there are certain invalid gapthis type vacuum chamber is inevitable, but the relative steam of high energy consumption and the leakage loss of the semi-sealed chamber, and X30 models almost does not exist other invalid gap, it can be said that this model of the vacuum is the highest efficiency, energy consumptionis the lowest.A X30AE configure a 1.1 kW two-stage rotary vane vacuum pump station to produce 15 bottles per minute is enough, that is the production of a thousand bottles for the vacuuming power consumption is less than a 1.1 kWh. The vacuum chamber is sealed with the formation of a completely closed space between the machine precision parts can easily achieve zero leakage, so it can reach unrivaled by other forms of the highest degree of vacuum, almost equal to the attainable degree of vacuum of the vacuum pump linked. Hermetically sealed vacuum hood bottle adaptability is obviously well, round bottle or square bottle, mouth large and small bodies bottles, almost can be applied on the inside of the vacuum chamber.The X30 for fully enclosed models, there are two advantages, one zero breakage rate, ultra-clean. whether holding the bottle with rubber mat hold claw or vacuum hood or tighten institutions and match cover agencies are cylinder driven, output force configuration by reasonable design and the application of precise adjustment, so all the movements are not rigid, Even deliberately so that it will not damage the grip or collision bottle bottle.Ultra Clean can be interpreted as the machine does not have mechanical transmission the oil, as well as parts easy clean-up characteristics. Of course, the drawback is the low capacity electrical pneumatic drive, each vacuum capping work cycle 6 cylinder moves caused the entire cycle takes longer. The way of Solve X30 series models low capacity is for the models provide excellent crew line performance.
