Abstract
The invention provides a vacuum packaging mechanism and method thereof, which is applied to a bag body and the packaging of a core material arranged in the bag body. The mechanism comprises an air extractor, a pressing device and a thermal-sealing device. The air extractor comprises a base and a vacuum tube part which can stretch out or retract from the base. When the base and the vacuum tube part of the air extractor stretch into the bag body to extract air, the pressing device can clamp the bag body so as to block the air from entering the bag body. When the vacuum degree in the bag body reaches a preset value, the vacuum tube part of the air extractor retracts into the base, and the thermal-sealing device can seal the cut of the bag body through thermal pressing. The invention can reduce the buckling of the film bag body caused by vacuumizing into minimum; when the vacuum degree reaches demands, the vacuum tube part can be led to retract from the part pushing against the core material and finish the process of thermal sealing; therefore, mass production of vacuum insulating packaging bodies are easy and limit on size is avoided.
Description
Technical field
The present invention relates to a kind of vacuum encapsulation mechanism and method thereof, be applied to contain the vacuum heat-preserving packaging body of core, particularly relate to method and mechanism thereof that a kind of use mode of vacuumizing is finished the encapsulation of vacuum heat-preserving packaging body.
Background technique
The transfer mode of heat energy has conduction, convection current and radiation, wherein makes the low-temperature preservation device (for example: forfeiture cold storage effect refrigerator), just heat energy enters in refrigeration or the refrigerating chamber with the wall body of conduction pattern by the low-temperature preservation device so that conduction pattern is the easiest.With regard to thermal energy transfer, solid dielectric has higher heat than gas medium and passes coefficient, and mostly gas medium be to transmit energy with convection type, so gas medium has preferable heat insulation effect than solid dielectric.But, then can further reduce to the heat biography effect of thermoconvection minimum if gas medium can be got rid of in the mode that vacuumizes in the structure of insulation or thermoinsulation material.
The making of general vacuum heat-preserving packaging body or vacuum heat-preserving sheet is that a core is inserted in the envelope, again air in the envelope is extracted and sealed out the opening of this envelope, and the wall body that so just can be positioned over the low-temperature preservation device is interior as thermoinsulation material.Select polyurethane (open-cell polyurethanefoams), aerogel (carbon/silica aerogel) of polystyrene (open-cell polystyrene foams), the perforate of perforate etc. for use when core, its effect of heat insulation is 3 to 7 times of conventional P U foam material, and when the ventilative and permeability rate of its envelope extremely hangs down, degree of vacuum in the envelope body is difficult for destroyed, so can be long-term used in refrigerator or other devices that need be incubated.
U. S. Patent announces the 6th, 106, discloses a kind of pump bowl that can be applicable on the vacuum encapsulation mechanism No. 449, its mainly be the tubular film passage that utilizes envelope with the vacuum suction head of spherical mouthful of tool between cooperate to finish and vacuumize.Exhaust tube is stretched in the film passage, and make a preceding end in contact core of bleeding, and smear the vacuum gel at spherical mouthful of place.Because the film passage is longer than exhaust tube, so can produce fold if the vacuum suction head will reach the bottom of film passage.Bleed head with after the tubular film channel engagement finishes when vacuum, can start vacuum pump, the vacuum gel that smear at spherical mouthful of place can prevent that air from infiltrating when vacuumizing.When reaching desired degree of vacuum, exhaust tube can be recessed core, the film passage of fold needs leveling originally, and heat sealing is finished in suitable position on the film passage then.
The vacuum suction head of above-mentioned U. S. Patent and tubular film interchannel cooperate and are difficult for, and insert fully at every turn and extract out all and need waste the more time.And the vacuum event requires exhaust tube elongated in order to avoid leak, thereby causes the pumpdown time long, so PR is difficult for promoting.
Summary of the invention
The purpose of this invention is to provide a kind of vacuum encapsulation mechanism and method thereof, its fold that can make the film bag be caused when vacuumizing is reduced to minimum.And utilize the telescopic air extractor of two-part to vacuumize, when degree of vacuum reaches demand, can make vacuum tube portion, and finish the technology of heat-sealing certainly against the withdrawal of core place.So can make the easy volume production of vacuum heat-preserving packaging body, and not have the restriction on the size.Also can reduce the cost of production of vacuum heat-preserving packaging body, and improve production capacity and quality.
For achieving the above object, the invention provides a kind of vacuum encapsulation mechanism, it is applied to the encapsulation that a bag and places the core in this bag, and comprises an air extractor, a press fit device and a hot sealing device.This air extractor comprises a base portion and can be from the vacuum tube portion that this base portion stretches out or regains.When the base portion of this air extractor and vacuum tube portion stretched into this bag and carry out air pump, this press fit device can be clamped this bag and enter in this bag to block air.Degree of vacuum in this bag reaches a predefined value, and then the vacuum tube portion of this air extractor regains in this base portion, and this hot sealing device can seal the opening of this bag with hot pressing.
For achieving the above object, the present invention also provides a kind of vacuum packaging method, and it is applied to the encapsulation that a bag and places the core in this bag, comprises the following step: provide aforementioned air extractor; With close this bag edge of the base portion of this air extractor; It is inner and bleed that the vacuum tube portion of this air extractor is stretched into this bag; When the base portion of this air extractor and vacuum tube portion stretch into this bag and bleed, by pressing to clamp this bag; Degree of vacuum in this bag reaches a predefined value, and then the vacuum tube portion of this air extractor regains in this base portion; And the opening that seals this bag.
Owing to adopt above technological scheme, the fold that the present invention can make the film bag be caused when vacuumizing is reduced to minimum, and utilizes the telescopic air extractor of two-part to vacuumize, when degree of vacuum reaches demand, can make vacuum tube portion certainly against the withdrawal of core place, and finish the technology of heat-sealing.So can make the easy volume production of vacuum heat-preserving packaging body, and not have the restriction on the size, also can reduce the cost of production of vacuum heat-preserving packaging body, and improve production capacity and quality.
