An upper sealing device for a tubular material package is a packaging device for a pillow-type package, comprising a feeder (10), a discharger (11), open end fixing means (20), a retractable part (22), open end sealing means (30), holding means (40), sensors (51) for a carrying plate (42), a controller (50), a package (60) and an object to be packaged (62). The open end sealing means (30) are provided on both sides of the open end fixing means (20), and the holding means (40) is provided below the open end sealing means (30). Discharging outlets (12) are arranged in a row on the discharger (11). Several open end fixing parts (21) are provided on the open end fixing means (20). Several holding parts (41) are provided on the holding means (40). Each discharging outlet (12) opens downwards, and each open end fixing part is provided correspondingly below each discharging outlet. The open end fixing means (20) moves up and down. Each holding part (41) is provided correspondingly below each open end fixing part (21). The open end sealing means (30) is opened or closed in the horizontal direction, and the holding parts (41) are also opened or closed in the horizontal direction. After the object to be packaged enters the package from the top to the bottom, the holding means clamps the package, so that not only the open end can be separated from the open end fixing means for sealing, but also the air in the package can be pressed out. |
