An apparatus for sealing an open end of a package comprises a first longitudinally extending sealing jaw, bearing mounted on a first eccentric shaft rotatable around a first rotational axis, and a second longitudinally extending sealing jaw, bearing mounted on a second eccentric shaft rotatable around a second rotational axis, the second sealing jaw being parallel with the first sealing jaw. At least one motor drives rotation around the first and second rotational axis in opposite directions, wherein the first and the second sealing jaws oppose each other, and are allowed to oscillate between sealing and open positions by moving towards and away from each other. A first and second transversally extending guiding bar cooperate with the first and second eccentric shaft via guiding pins running in guiding grooves, such that transverse play between the first and the second eccentric shaft and the first and second sealing jaw is allowed.

A heat sealer module for a heat-sealing station of a packaging apparatus has a sealing belt for contacting a terminal portion of semi-sealed packages and for guiding the terminal portion of the semi-sealed packages along a main movement direction; the heat sealer module also has a first driving belt and a second driving belt to assist in accompanying the packages in proper position for sealing. A heat sealer having opposed heat sealer modules. A packaging apparatus for heat sealing packages having a vacuum chamber with an elongated opening and a conveyor for receiving semi-sealed packages and for moving the semi-sealed packages relative to the vacuum chamber is disclosed. The packaging apparatus includes evacuation means for evacuating gas present in the semi-sealed packages and forming evacuated semi-sealed packages. The packaging apparatus includes the heat sealer for heat sealing the terminal portion of each evacuated semi-sealed package thereby forming heat sealed packages.

A flexible sealing tube is described that is adapted to be installed in and extend along a bore in the ground for use in a system for exchanging of energy with the ground. The flexible sealing tube has a first tube end to be installed at an inner part of said bore, and the flexible sealing tube is closed in the first tube end. The flexible sealing tube also has a first channel and a second channel extending in a longitudinal direction (L) of the flexible sealing tube, the first and second channels being in fluid connection with each other. The first and second channels are formed by the flexible sealing tube.

A vacuum packaging device includes a hexahedral housing having a space inside; a grip unit in which a pair of grip bars selectively come into surface contact with each other above a front side of the housing; a suction nozzle unit which moves forward and backward along a guide inside an inner space of the housing; a pair of heat-pressing members which are respectively provided in the pair of grip bars; and lifting and lowering means for lifting and lowering an upper grip bar of the pair of grip bars and an upper heat-pressing member of the pair of the heat-pressing members inside the inner space of the housing by a process step.

An apparatus for vacuumizing and sealing a package includes a plurality of platens and vacuum chambers, each chamber adapted to mate with a dedicated one of the platens; a conveying system for conveying the platens and chambers along a generally angular path having a single axis of rotation; an automated loading assembly having a linear component and configured to load a package onto each of the platens; an automated unloading assembly having a linear portion and configured to unload a vacuumized, sealed package from each loaded platen onto an outfeed conveyor; and a vacuumizing/sealing system configured to cause relative movement of each chamber/platen pair, along a portion of the angular path, to form therebetween an air-tight enclosure accommodating the package and effect vacuumization and sealing of the package.

The present invention discloses a heat fusing device for a smart trash receptacle, including: a heating wire for fusion-cutting and thermally sealing an open end of a trash bag, the heating wire being connected to a heat-fusing circuit; a base having heat-resistant and insulating properties, the base having a first end surface on which the heating wire is arranged; and a control mechanism communicatively coupled to the heat-fusing circuit for control thereof. The present invention also discloses a smart trash receptacle incorporating the heat fusing device and a method for controlling a heat fusing temperature. With the present invention, during automatic bagging by the smart trash receptacle, good contact between the heating wire and the trash bag can be ensured while preventing adhesion of the trash bag. This results in improved sealing quality and enables the fulfillment of two tasks, i.e., thermoplastic sealing and thermal fusion-cutting, in the same action of the heat fusing device. As a result, higher automatic bagging quality and reliability are obtainable at lower bagging control difficulty and reduced bagging cost. Moreover, control in the system is simplified, and the stability and reliability of the system are increased.

A method of sealing reinforced packages. The method can comprise moving an open-ended package in a downstream direction on a package conveyor by engaging the open-ended package with a chain flight of the package conveyor moving in the downstream direction. The method further can comprise forming a bag with a closed end by engaging at least a seal portion of a tail section of an open-ended tube portion of the open-ended package between the chain flight of the package conveyor and a hot plate positioned adjacent the package conveyor. The chain flight can move with the tail section in the downstream direction relative to the hot plate, which can transfer thermal energy to the tail section to at least partially form a seal along the seal portion in the tail section to at least partially form the closed end of the bag.
