The invention discloses a five-side quick packaging mechanism used for thermal insulation materials and belongs to the field of packaging of thermal insulation materials. The mechanism comprises a workbench top, an upper pressing plate and a plurality of side plates. The upper pressing plate is driven by an upper pressing plate drive system to make vertical movement; the side plates are driven byside plate drive systems and make horizontal movement along the workbench top; and the workbench top, the upper pressing plate and the side plates can be combined to form a square or rectangular sealing cavity. By adopting a combined and movable frame type structure, automatic and quantitative glue dispensing is achieved while five sides of the thermal insulation materials are packaged, the technological process is simplified, in addition, the labor cost is saved, and the production efficiency is improved.
