At least two eccentric shafts are pivoted on each carousel, and at least one respective sealing head is pivoted on each one of the shafts at an axis. Each eccentric shaft includes a respective slider that can move along a fixed contoured profile for the movement of the respective shaft. A linkage connects corresponding levers which are substantially integral with the eccentric shafts. The levers are opposite to the point of coupling to the respective slider. Each sealing head is controlled by orientation elements which are integral with the respective carousel.

A metal-resin joining device joins a thermoplastic resin plate (12) to a metal plate (13) by melting the resin plate (12) in contact with the metal plate (13) through heating an exposed face of the metal plate (13) by one-sided resistive heating. The metal-resin joining device has a center electrode (24a) that is brought in contact with the metal plate (13) and a peripheral electrode (24b) that is brought in contact with the metal plate (13) to annularly surround the center electrode (24a) and to which a current flows from the center electrode (24a) via the metal plate (13), wherein the peripheral electrode (24b) is made of a metal material having a higher electrical resistance than the center electrode (24a).

A device for joining filter bags includes two operating units located on opposite sides of a continuous tubular strip of filter material movable along a feed direction; each operating unit includes a supporting body, a sealing head connected to the supporting body and two kinematic units equipped with a corresponding eccentric rotary system for moving the supporting body along a first trajectory and to move the sealing head between a position of contact with the strip and a position away from the strip; each operating unit includes a carriage associated with the sealing head for and slidably connected to the supporting body to translate in both directions along a second trajectory.

A welding apparatus for use in welding first and second sheets of material together includes a seal die, a platen, a control unit, and a power source adapted to provide energy to the seal die. The seal die is made of a conductive material and is configured to impart thermal-mechanical energy to the first and second sheets of material. The seal die includes a bottom surface configured to contact the first sheet, an inner edge, a chamfer extending between the bottom surface and the inner edge, a first blend radius, and a second blend radius. The first radius extends between the chamfer and the bottom surface, while the second radius extends between the chamfer and the inner edge. The platen is configured to support the second sheet, while the control unit is programmed to cause the seal die to be directed towards the platen.

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.

An induction welding assembly and inductive welding method is disclosed. A tooling block includes a workpiece zone, a conductive heat generation and transfer member, and a heat shield, with the conductive heat generation and transfer member being disposed between the workpiece zone and the heat shield. A first workpiece and a second workpiece may be disposed within the workpiece zone such that the first workpiece is disposed between the conductive heat generation and transfer member and the second workpiece. The heat shield, conductive heat generation and transfer member, first workpiece, and second workpiece may be pressed together.
