Disclosed is a sealing apparatus wherein, as a drum (5) and a rotary base (6) are rotated together, a follower (10a) of a rocking support member (9) rockably provided on the outer periphery of the rotary base (6) is guided along a cam groove (15c) of a cam member (15) to drive the rocking support member (9) to rock. When the rotary drum (5) reaches a predetermined rotational position, an anvil (14) supported by the rocking support member (9) is urged onto a horn (8), and then, when it reaches another rotational position, the anvil (14) is moved away from the horn (8). Since the anvil (14) is driven by the rocking motion of the rocking support member (9), entire operation becomes quite simple, and a continuous soft work can be certainly clamped between the horn (8) and the anvil (14).

An apparatus for a laser transmission welding process for attaching a synthetic filter material to a filter tower frame in an ink jet printer cartridge. The apparatus includes a laser beam source and a filter clamping fixture containing a base, slide rods attached on first ends thereof to the base, an optics support plate attached to second ends of the slide rods, a movable platform for holding an ink cartridge slidably disposed on the slide rods between the base and the optics support plate, a platform moving device for translating the platform to and from a laser welding position, a laser beam transparent plate suspended by support legs from the optics support plate to a position between the movable platform and the optics support plate. The apparatus greatly improves synthetic filter attachment to a filter tower frame in an ink cartridge.

An apparatus for closing packages made from a heat-sealable material has sealing jaws, which are subdivided by a recess or by slits into two zones. What is essential is that the two zones are eastically joined together by means of a connecting web, so that when a transverse seam is sealed, it is possible to compensate for a different number of layers of packaging material along the transverse seam. The apparatus according to the invention is relatively simple in structure and makes high sealing qualities attainable.

Sealing heads for heat sealing the tops of continouously movable upright pouches are spaced angularly around a continuously rotatable turret and seal the pouches after steam has been introduced into the pouches and as the pouches move in an arcuate path extending around the turret. Each sealing head includes a pair of heated sealing bars and further includes a cam-operated actuator which sequentially lowers the bars, closes the bars, opens the bars, and then raises the bars as the bars rotate with the turret.

The present invention relates to a food vessel packing apparatus having a vacuum packing function, and more particularly, to a food vessel packing apparatus having a vacuum packing function, which that thermally bonds a film to a top of a food vessel in a vacuum state to seal the food vessel. The food vessel packing apparatus having a vacuum packing function of the present invention, which thermally bonds a film to a top of a food vessel to seal the food vessel, includes: a base configured to include an accommodating groove in which the food vessel is accommodated, the accommodating groove being formed at a top of the base; a cover configured to cover the top of the base; a first heater mounted on a bottom of the cover, and configured to thermally bond a film, disposed at a top of the food vessel, to a top border of the food vessel; a gasket provided in a closed-curve shape along a circumference of the first heater, outside the first heater, and mounted on a bottom of the cover or the top of the base; and a vacuum pump disposed inside the gasket that includes a sucking port formed in a closed-curve shape, wherein, the vacuum pump emits internal air of the food vessel to an outside through a space between the film and the top of the food vessel, and the internal air of the food vessel is emitted to the outside, and then the first heater thermally bonds the film to the food vessel.
摘要:
A heat-sealing apparatus comprising a pair of opposed hot plates and a pair of hot plate-mounting blocks to which said hot plates are mounted, respectively. The hot plates respectively have pressing surfaces adapted to be pressed against each other with superimposed film sheets held therebetween during sealing; and mounting surfaces formed at opposite sides to said pressing surfaces. The hot plate-mounting blocks respectively have support surfaces. The hot plates are mounted to said hot plate-mounting blocks in such a manner that the mounting surfaces are pressed against the support surfaces, and that the hot plates can thermally expand and contract in a sealing direction without being restrained by said hot plate-mounting blocks. In another aspect of the invention, the mounting surfaces are formed on respective surfaces extending substantially perpendicular to the pressing surfaces and the hot plates are mounted on respective support surfaces formed on the hot plate-mounting blocks.

A heat sealing jaw assembly for effecting a heat seal of at least two juxtaposed heat sealable sheet materials is described. Preferably, but not exclusively, the heat sealing jaw assembly is adapted for use in a form, fill and seal machine forming thermoplastic bags. The heat sealing jaw assembly comprises a first and a second metal jaw member, each having a heating element for heating the jaw members. Each of the jaw members has an end face disposed in facial alignment with one another. A ribbon member is secured to each of the end faces and disposed in planar alignment with one another. The ribbon member is made of soft material having rubber-like properties and capable of conducting heat from the sealing jaw to a fusing temperature to melt the heat sealable sheet materials. The first and second jaw members are reciprocatable towards and away from one another to press the aligned heated ribbon members against opposed sides of at least two juxtaposed heat sealable sheet materials disposed between the jaw members to effect a heat seal.

Apparatus for manufacturing heat sealed products from high temperature film materials exhibiting superior barrier properties, such as films made from LCP resin. The apparatus has in relevant part a first compression member having a heating element that is capable of being continuously or intermittently heated to a temperature of about 300.degree. C. (c. 575.degree. F.) backed by a layer of material capable of supporting the heating element, a second compression member that opposes the first compression member and having an electrically conductive tubular sealing element, capable of being flash-heated by means of a pulse of electric current to a temperature of about 425.degree. C. (c. 800.degree. F.) and immediately flash-cooled to room temperature or below by means of forcing vortex-chilled coolant fluid through the tubular lumen, backed by a layer of material capable of supporting the sealing element, and two floating sheets or tapes of high-temperature release material disposed therebetween.

A transverse sealer for a packaging machine has a pair of seal jaws for sealing a film after it is made into the shape of a bag by a former and the bag is filled with articles to be packaged. The pair of seal jaws are disposed on opposite sides of the path of the film and downstream to the former. A pair of rotary arms supporting these seal jaws is moved towards and away from each other such that the seal jaws move in straight trajectories along the path of the film and is so controlled that the compressive force between the seal jaws can be maintained at a specified level according to the thickness and material property of the film.
