Patent Name Gas Packing Bag Manufacturing Method and Equipment Patent Applicant Jiamei Industry Co., Ltd. (Taiwan, China) Principal Applicant Address 1/F, No.54, Tianmu West Road, Shilin District, Taipei, Taiwan Inventor Chen Yuhua Application (Patent) No. 200410059963.5 Application Date 2004.06.25 Certification date Approval Notice No. 1712324 Auditing announcement date 2005.12.28 Manual CD No. D0552 Main classification number B65D81/03 Classification No. B65D81/03 Division Original application No. Priority item Abstract Manufacturing method for gas packaging bags, steps are : The upper film, air valve film and lower film of the packaging bag are respectively installed on the respective discharging rollers to drive rotation so that the upper film, the air valve film and the lower film are discharged, and the guiding rollers guide the upper film separately. The forward direction of the air valve film, the lower film, etc.; the leveling roller is leveled; the first copper mold, the second copper mold, and the front and back envelope copper molds perform high thermal printing on the passed film; the cooling mold performs cooling and shaping; The copper mold performs high-temperature printing on the upper film and the air valve film, and combines with the upper film and the air valve film to perform another high-temperature printing together with the lower film. Before and after the envelope was cooled copper mold and die were decreased, then the retractor of the formed package from the gas bags retractor roller. The equipment is provided with a number of guide rollers: the first upper and lower leveling rollers, the second upper and lower leveling rollers, and the take-up rollers. The first copper mold, the second copper mold, and the front and back copper bags are also provided. Mold, cooling mold and other components. Sovereignty Clause 1. A method for manufacturing a gas packaging bag, wherein the steps of: manufacturing the upper film, the air valve film, and the lower film for manufacturing the packaging bag are respectively arranged on the respective discharging rollers, and are driven by the driving device. Rotation, the upper membrane, the valve membrane, the lower membrane, the discharge; a plurality of guide rollers, respectively, guide the membrane, the valve membrane, the lower membrane and other forward direction; the upper and lower leveling roller, through the gap The film is leveled; the first copper mold, the second copper mold, and the front and back envelope copper molds are raised and lowered by a driving device to perform high thermal printing on the passed film; the cooling mold is used to cool and shape the passed film; The air valve film is guided through the first upper and lower leveling rollers, the first copper mold is lowered, the upper film and the valve film after the leveling are subjected to high-temperature printing, and the upper film and the air valve film are combined. Together with the film together through the second upper and lower leveling film for another high-temperature printing; then before and after sealing the copper mold and the cooling mold are lowered, so that the gas packaging bag has been fully formed, and finally by the rolling wheel pair Formed gas bags into Retractor.
