Cargo Sealing-Package Apparatus

Abstract

A cargo sealing-package apparatus comprises a larger plastic film coated with a layer of adhesive and an appropriate-thick paper base board, both larger than a cargo, and cushion elements with elasticity are adapted to protrusions extending from the cargo. The cargo is first placed flat onto the base board and, together, moved to a conveying platform of a preparation area (a cargo-feeding zone) to be transported into a working area (a vacuum-molding zone) and lifted upwards via an ascending/descending machine into a vacuum-heating area, bringing up air to inflate the plastic film undergoing pre-heating operation. Then, the air is drawn out to thermo-seal the plastic film around the shape of the cargo and adhere it in vacuum-binding onto the surface of the base board. Finally, the cargo accurately bound in a vacuum space is moved to a cargo-outlet area, achieving the benefits of anti-shock, humid-proof, dustproof, and anti-oxidized functions thereby.

1 . A cargo sealing-package apparatus, comprising a plastic film coated with a layer of adhesive thereon and an appropriate-thick paper base board that are utilized to bind a cargo according to its external shape thereof wherein the cargo is first placed flat onto the base board and, together with the base board, moved to a conveying platform of a preparation area (a cargo-feeding zone) to be transported into a working area (a vacuum-molding zone); at the working area, the cargo and the base board are lifted upwards via an ascending/descending machine into a vacuum-heating area, permitting the plastic film undergoing pre-heating operation to be inflated by air brought up via the ascending cargo and the base board; then, the air is drawn out, permitting the plastic film to thermo-seal around the external shape of the cargo and adhere flat onto the surface of the base board in vacuum-bound attachment thereto; thus, the inner surface of the plastic film affected by the vacuum suction will descend along the depressed areas of the cargo to form an airtight conjoining portion therewith, permitting a sheer vacuum space formed therein; then, the extra plastic film is cut along the outline of the base board to complete the sealing-package of the cargo before the cargo is conveyed to a cargo-outlet area, providing the benefits of anti-shock, humid-proof, dustproof, and anti-oxidized functions as well as avoiding the overuse of the conventional cargo package to save the cost thereof. 
     
     
         2 . The cargo sealing-package apparatus as claimed in  claim 1  wherein the plastic film is larger than the base board thereof. 
     
     
         3 . The cargo sealing-package apparatus as claimed in  claim 1  wherein the plastic film and the base board are both larger than the cargo thereof. 
     
     
         4 . The cargo sealing-package apparatus as claimed in  claim 1  wherein one or more than one of cushion elements each equipped with elasticity can be adapted to protrusions sticking out from the cargo thereof. 
     
     
         5 . The cargo sealing-package apparatus as claimed in  claim 1  wherein the inner surface of the plastic film affected by the vacuum suction thereof will descend along the depressed areas of the cargo to form an airtight conjoining portion. 
     
     
         6 . The cargo sealing-package apparatus as claimed in  claim 1  wherein the plastic film is composed of EVA (a bottom layer), and LDPE (a top layer) thereby.
