Apparatus for vacuumizing and sealing packages on rotating carousel
A recently granted patent (Publication Number: US11994237B2) discloses an innovative apparatus designed for vacuumizing and sealing multiple packages efficiently. The apparatus features a rotating carousel with a plurality of platens that travel along a specific path, including angular and linear portions, around a single axis of rotation. A linear-motion mechanism, embodied as a linkage assembly, enables the platens to extend radially outward and rotate while remaining aligned with the direction of travel. Additionally, a series of vacuum chambers are strategically positioned to engage each platen, forming an airtight enclosure as they move synchronously along the carousel.
Furthermore, the apparatus includes a unique linear-motion mechanism with extension arms secured to the carousel, allowing for precise movement of the platens. Each platen is equipped with cam followers that interact with a cam track positioned below the travel path, ensuring smooth and controlled motion. The design also incorporates a biasing mechanism to maintain contact between the cam followers and the cam surfaces. With features like unloading portions for package removal and precise alignment throughout the rotation, this apparatus offers a comprehensive solution for vacuumizing and sealing packages with efficiency and accuracy.
