A process is provided for heat sealing substrate layers. The process comprising: conveying an upper die having a heating conductor and a lower die having a heating conductor to a sealing region, where a substrate is applied to one or more items; activating a power supply system; monitoring, via the power supply system, a temperature of the heating conductor of the upper die when in the sealing region; monitoring, via the power supply system, a temperature of the heating conductor of the lower die when in the sealing region, wherein the monitoring of the temperature of the heating conductor of the upper die is performed independently of the monitoring of the temperature of the heating conductor of the lower die; supplying power to the upper die based on the temperature of the heating conductor of the upper die; supplying power to the lower die based on the temperature of the heating conductor of the lower die, wherein the power is supplied to the lower die independently of the power being supplied to the upper die.

A protective packaging formation device is provided herein. The device includes an inflation assembly having a fluid conduit that directs fluid between overlapping plies of a polymeric web. The device also includes a driving mechanism that drives the film in a downstream direction. The device also includes a sealing mechanism that includes a thin film heater that heats the plies to create a longitudinal seal that seals the plies of film together. The driving mechanism drives the web such that the web slides across the heating assembly in a downstream direction to trap fluid between the plies.

A system includes a dip tube, a feed line, and a check valve. The dip tube is inserted through an opening in a source of chemical precursor and into the chemical precursor in the source. A portion of the feed line is located in the dip tube. The feed line passes out of the dip tube. The chemical precursor is capable of flowing out of the source through the feed line in a downstream direction. The check valve is located in the portion of the feed line in the dip tube. The check valve permits the chemical precursor to pass substantially only in the downstream direction. The feed line is coupled to a transfer pump that draws the chemical precursor out of the source through the portion of the feed line in the dip tube.

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 for welding thermoplastic components, in particular, thermoplastic fiber composite structural components for an aircraft or spacecraft, having the following steps. Arranging an insert, which has a conductor structure having a plurality of parallel electrical conductor elements, in a joining zone between a first thermoplastic component and a second thermoplastic component such that at least some portions of the parallel electrical conductor elements are located in the joining zone; locally melting the components in the region of the joining zone by supplying current to the conductor structure; disconnecting the connector elements; and removing the insert from the joining zone by pulling out the disconnected conductor elements. An insert for the resistance welding of thermoplastic components is also provided.

An intelligent trash can includes a closing and packing mechanism for automatic closing of a garbage bag. The closing and packing mechanism include a pair of first pressing rods and a second pressing rod. The pair of first pressing rods are configured for being synchronously approached or synchronously moved away under the driving of a first belt transmission unit. The second pressing rod is perpendicular to the pair of first pressing rods. The second pressing rod is configured to perform linear reciprocating motion along a length direction of the pair of first pressing rods under the driving of the second belt transmission unit.

A rechargeable sealer with storage function includes a casing, an electric heating module, a circuit board, a supporting base, a press bar, a spring-back mechanism, and a sliding plate. The casing is provided with an accommodating chamber, in which are provided with a fore contact element and a rear contact element. A rechargeable battery is positioned in and between the fore contact element and the rear contact element. The circuit board, provided with an external slot, is disposed in the accommodating chamber, featured in charging the rechargeable battery. The press bar is provided with a sliding slot, and is pivotally connected with the pivoting shaft of the supporting base, served as a pressing structure corresponding to the casing.

A process for packaging a product arranged on a support comprising unrolling a film, moving the film to a packaging assembly defining at its inside a packaging chamber, progressively moving a number of supports inside the packaging chamber of the packaging assembly, closing the packaging chamber with the film sheets held above the respective support, optionally causing one or both of: a gas withdrawal from the hermetically closed packaging chamber and gas injection of a gas mixture of controlled composition, heat sealing the film to said support, wherein the heat sealing uses one or more heaters having heating surfaces which are heated for discrete and short time periods only. An apparatus for performing the above process is also disclosed.
