The invention relates to an automatic pressing power device of a vacuum packaging machine, wherein the automatic pressing power device comprises main body, power plate and power airbag, wherein the power plate is connected with the main body through the power airbag and forms a telescopic closed cavity; the bottom of the main body is provided with an air nozzle communicated with the closed cavity. The automatic pressing power device provided by the invention does not need to tighten the upper cover artificially, and has the characteristics of simple structure, low cost, high structural stability, long service life and the like.

A method and apparatus for sealing a plastic enclosure is provided. The apparatus includes a handle including elements pivotally coupled together at a first end. The apparatus also includes a pair of spaced apart heating elements positioned along an inner surface of an element and connected to a power source where a longitudinal axis of the heating elements is oriented parallel with a longitudinal axis of the element. Plastic material including first and second plastic layers is positioned at an interface between the second elements. Upon pivoting the first elements from an open position to a closed position the heating elements increase a temperature at the interface to melt the plastic material and form a pair of spaced apart seals between the first and second plastic layers.

A vacuum sealer includes: a housing comprising a vacuum chamber therein; a vacuum pump in fluid communication with the vacuum chamber; a sealing mechanism adjacent a periphery of the vacuum chamber; a valve positioned and configured to releasably seal the vacuum chamber, the valve movable between a first position, in which the valve forms a seal with the sealing chamber, and a second position, in which the valve does not form a seal with the sealing chamber; and a controller operatively connected with the vacuum pump, the sealing mechanism, and the valve. The controller is configured to move the valve from the first position to the second position during sealing.

The present disclosure discloses an automatic trash bag sealing device for an automatic cat litter box and an automatic cat litter box. In the automatic trash bag sealing device, a drive motor drives a first rod and/or a second rod to rotate, thereby driving a pushing member to move towards a sealing member, and the trash bag is sealed when the sealing member is interfaced with the pushing member. The sealing device has fewer parts and is simple to assemble, effectively reducing the difficulty of process assembly and the overall cost of the automatic cat litter box.

An apparatus for filling and sealing bags intended for containing banknotes includes a generally parallelepiped-shaped container, with side walls, a bottom and an upper lid provided with an opening for allowing entry into the container of a bag, made up of flexible plastic film, and of banknotes intended to be introduced into the same bag. The apparatus includes a pair of sealing bars arranged at the upper end of the container and a system for controlling and moving the bars between their respective opening and closing positions. The control and movement system of the sealing bars has a motor for driving a shaft adapted to rotate at least one driving pulley arranged below in correspondence with a vertical edge of the container, a kinematic connection for closing the bars comprised of a combination of cables and tension springs connecting the driving pulley to the sealing bars and a kinematic connection for opening the bars comprised of a combination of cables and tension springs connecting the sealing bars to a respective fixed anchor point of the container.

The present invention relates to a machine for filling bags with a granular product comprising a filling station, a welding station, and a cooling station. The machine comprises a supporting device for supporting the bags below the stations. The device comprises a supporting surface assembled in a pivoting manner on a pivot shaft, and actuating means. The supporting surface has a first supporting segment for supporting the bags of the filling and welding stations on one side of the pivot shaft and a second segment for supporting the bag of the cooling station on the opposite side of said pivot shaft. The supporting surface can pivot in an alternating manner around said pivot shaft for moving the base of the bag which, in operation, is located in the filling station during filling. The invention also relates to a filling method.

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.

An inline packaging machine for automatically accommodating and filling different sized containers, such as pouches, to reduce changeover time and thereby improve operating efficiency of the machine. The machine includes stations disposed longitudinally along a center line of the machine, including a first carrier track opposing a second carrier track with respect to the center line. A first clamp is disposed on the first carrier track and at least a second clamp is disposed on the second carrier track wherein the clamps are configured to releasably secure first-sized pouches for filling. The pouches are advanced inline from a setup station through an opening station to a filling station for filling with contents. The filled pouches are then advanced to a sealing and discharging station. A control system automatically adjusts the distance between the corresponding clamps to accommodate second-sized and/or third-sized pouches for inline processing and filling.

A heater includes: a heat generation unit that generates heat when energized; an electric wire that is attached to the heat generation unit and supplies electric current to the heat generation unit; a ground wire that is attached to the heat generation unit and is grounded; a conductive cover that includes an electrical conductor, is attached to the heat generation unit, and is grounded; and an insulating cover that has an electrical insulating property and at least partially covers the conductive cover.
