Embodiment Construction

[0013] see figure 1 with figure 2 In this embodiment of the present invention, a sealing method for airbag pressurized vacuum insulation panels includes at least one pair of heat-sealing strips arranged in parallel in the frame 1, each of which is composed of an upper heat-sealing strip 3 and a lower heat-sealing strip 3. The sealing strip 4 is composed of an air bag 2 on the upper side of the upper heat sealing strip 3; the sealing edges of the two ends of the vacuum insulation board 10 are placed between the upper heat sealing strip 3 and the lower heat sealing strip 4; the valve 6 is opened to fill the air bag 2 The high-pressure air from the air source (such as an air storage tank) 8, when the air pressure value reaches the set value, that is, after the airbag inflation time is maintained for 8 seconds, the valve 6 is closed to complete a sealing process. Utilize the expansion of the air bag 2 to push the upper and lower heat-sealing strips 3 and 4 to squeeze relatively ...

Abstract

The invention relates to an air bag pressurization sealing method for a vacuum heat insulation plate. In the air bag pressurization sealing method, at least one pair of heat sealing strips are arranged in a frame in parallel, each pair of the sealing strips comprise an upper heat sealing strip and a lower heat sealing strip, and the air bag pressurization sealing method is characterized in that an air bag is arranged on the upper side of the upper heat sealing strip or/and on the lower side of the lower heat sealing strip; the sealing edges at the two ends of the vacuum heat insulation plate are placed between the upper heat sealing strip and the lower heat sealing strip; and high-pressure air is filled into the air bag, the expansion of the air bag is utilized for pushing the upper and the lower heat strip strips to approach each other and perform extrusion oppositely, and the purpose of sealing the vacuum heat insulation plate is realized. The air bag pressurization sealing method disclosed by the invention has the beneficial effects that an air bag sealing structure is simple, when sealing is performed, the force applied to the heat sealing strips is uniform, and the heat sealing effect is better.

Description

technical field [0001] The invention relates to a sealing method of a vacuum heat insulation panel pressurized by an air bag, which is used for sealing in the production process of the vacuum heat insulation panel. Background technique [0002] In the production process of the vacuum heat insulation panel, it is necessary to heat-press seal the mouth of the sealing film of the vacuum heat insulation panel after vacuuming. The sealing machine of the prior art adopts a mechanical mechanism when pressing down the heat sealing strip, and its disadvantages are complex equipment, high production cost and failure rate, and frequent maintenance. Contents of the invention [0003] The purpose of the present invention is to provide a method for sealing vacuum insulation panels with air bag pressurization to solve the problems of complex equipment, high cost and high failure rate in the prior art. [0004] The technical solution of the present invention is: a method for sealing vacu...
