Abstract

The invention discloses a vacuum heat insulation panel air pressure sealing machine which comprises a box body, a vacuumizer, a commodity shelf and a rack, wherein two ends of the commodity shelf are provided with sealing devices; each sealing device comprises an upper layer of bakelite, a lower layer of bakelite and a silica gel bar which is adhered on the lower layer of bakelite; an arc-shaped supporting frame is arranged below the upper layer bakelite; the arc-shaped supporting frame is provided with two heating seal bars; the upper layer of bakelite is provided with an air bag internally; and the air bag is connected with a circumscribed air source. The sealing process of the vacuum heat insulation panel air pressure sealing machine comprises the following steps: placing a heat insulation panel on the commodity shelf; starting the vacuumizer; carrying out vacuumizing treatment for the box body; controlling the pressure of air in the box body within the range from 0.6 to.002Pa; inflating the air bag in the upper layer bakelite; pressing the upper layer of bakelite on the lower layer of bakelite, wherein 2-4Pa pressure is generated; heating the seal bars and simultaneously heating and sealing an aluminum foil blocking bag and molding for one time; controlling the time of the heating and sealing to be 1-3 seconds; and taking the sealed vacuum heat insulation panel from the box body of the sealing machine.

Description

technical field [0001] The invention relates to a vacuum heat insulation board air pressure sealing machine and a sealing process for sealing a vacuum heat insulation board by using the air pressure sealing machine. Background technique [0002] Vacuum insulation panels are currently the most advanced high-efficiency thermal insulation materials in the world, and their thermal conductivity is only 0.004w / m.k. Vacuum insulation panels adopt the principle of vacuum insulation and are composed of core insulation materials, gas adsorption materials and aluminum foil barrier bags. The core The heat insulation material is closely matched with the aluminum foil barrier bag, which can effectively avoid heat transfer caused by air convection, and the thermal conductivity is greatly reduced. Therefore, how to make the core heat insulation material and the aluminum foil barrier bag cooperate more closely has become the focus of the work of manufacturers and researchers. The existing s...
