The invention relates to a drive unit for a strapping device for strapping an item to be packed with a plastic tape which is laid around it, having a motorized tensioning device and a motorized welding device for the plastic tape, wherein the tensioning and the welding device can be driven by the same electric motor which can be brought alternatively into an operative connection with said devices with freewheels being connected in between. The problem has occurred in drive units of this type that they are relatively complicated to assemble and have problematic operational reliability under certain boundary conditions. In order to bypass said problems, it is proposed to provide the electric motor with at least one shell extension which protrudes beyond it at one axial end, with the result that the drive elements which have up to now been mounted separately in the housing of a strapping device can be supported directly on the electric motor which then acts as a drive unit.

A handheld electric packing machine having a strap press structure, vibrating component, cutter, and strap press spacer matching the strap press structure. The strap press structure connects to the vibrating component or is part of the vibrating component. The vibrating component is a swing vibrating component capable of rising and falling. The machine has a downward pressing mechanism and rising reset mechanism for the vibrating component. The vibrating component swings leftward and rightward relative to the lengthwise direction of a packing strap. The machine has a leftward and rightward swing driving device for the vibrating component. The machine has a manually downward pressing operating mechanism with a lock, which is locked when the vibrating component is pressed downwards until the strap press structure is located at a strap press position. The downward pressing operating mechanism cannot retreat after the manually downward pressing is removed.

A strapping device includes a body, a tensioner, and a handle. The body can have a first body end, a second body end, and a base extending between the first body end and the second body end. The tensioner can be coupled with the body and adjacent to the base, the body defining a strap axis between tensioner and the base, the tensioner applies a force to a strap received by the body along the strap axis. The handle can extend between a first handle end coupled with the first body end and a second handle end coupled with the second body end. The handle can be oriented at an angle relative to a plane parallel to the strap axis, the angle greater than or equal to 15 degrees and less than or equal to 45 degrees.

Provided is an auto strapping packaging tool having a clamp fixing apparatus including a body assembly, a tension module partially coupled to the body assembly and providing a tensile force to a plastic band using a first motor, a feed wheel part rotated by the first motor about a first shaft, and a clamp part disposed around the feed wheel part to be rotated about a second shaft, a welding module including a second motor and a third motor and providing a friction force to the plastic band to which the tensile force is applied by the tension module, a hooking part provided with a first hooking element axially rotatably disposed in the body assembly and a second hooking element fixedly disposed in the body assembly, and a lever unit axially rotatably coupled to the body assembly.

Provided is an inner module structure of an auto strapping packaging tool including a tension module in which first power generated by a first dedicated motor disposed at a rear side is transmitted to a front side to provide a tensile force to a packaging plastic band, and a welding module which is disposed at one side of the tension module, and in which a gripper unit is opened or closed by second-1 power due to axial rotation in a forward direction of a second dedicated motor disposed at a rear side, and the gripper unit linearly reciprocates by second-2 power due to axial rotation in a reverse direction of the second dedicated motor to provide a friction force to the plastic band to which the tensile force is applied through the tension module.

The strapping apparatus including a connecting device for generating a permanent connection, in particular a welded connection, at two regions, situated one above the other, of the loop of the strapping band. The strapping apparatus is configured to achieve the release of the tensioning element from the strapping band reliably to avoid or reduce adverse characteristics attributed to the release of the tensioning device from the band.

Various embodiments of the present disclosure provide a mobile strapping device for strapping packaged products using a loop of wrapping strap. The strapping device includes a tensioning device for applying tension to the strap and a connecting device for connecting two overlapping portions of the strap. The tensioning device includes a rotatable tensioning wheel and a tensioning plate. The tensioning wheel is supported by a rocker that is pivotable to change a distance separating the tensioning wheel and the tensioning plate.
