A strapping machine and head are provided including a mounting base, a sealing assembly including a cutter for cutting the strapping tape and a sealing element for welding a strapping tape. The sealing assembly, which is slidably disposed on the mounting base, includes a first, second, and third clamping mechanism, for clamping the strapping tape. A belt feeding assembly including a first motor, a driving wheel and a guide block fixedly disposed on the mounting base. The driving wheel is rotatably disposed on the mounting base and an arc-shaped belt feeding channel is formed between the driving wheel and the guide block. The first motor drives the driving wheel to rotate, and a driving assembly drives the sealing assembly close to or away from the driving wheel. A balanced tension is applied to a strapping tape through a strapping machine head to improve the strapping quality of the strapping machine.

A machine core of a packing machine, a strap feeding and returning and strap tightening device thereof includes a first roller (1) and a second roller (2). The second roller (2) is controlled by a control mechanism to move to a first matching state with the first roller (1) and to move out of the first matching state with the first roller (1) to a second matching state. The first roller (1) is connected with a first transmission gear (10) capable of driving the first roller (1) to rotate. The second roller (2) is connected with a second transmission gear (20) capable of driving the second roller (2) to rotate. The second transmission gear (20) and the second roller (2) conduct synchronous movement. The first transmission gear (10) takes in power through a gear transmission mechanism to drive the first roller (1) to rotate. The second transmission gear (20) takes in power through the gear transmission mechanism. The second transmission gear (20) moves into a first gear matching state with a gear transmitting the power to the second transmission gear (20) through the movement, and moves out of the first gear matching state. The machine core has a simple structure, is capable of reducing failure rate, and has a good packing effect. Besides, strapping force, strap feeding length and temperature as well as ironing adhering delay may be regulated by means of a potentiometer.

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. The mobile strapping device includes a motor that is operably connectable to the rocker or the tensioning wheel such that the motor causes pivoting of the rocker or rotation of the tensioning wheel when operating in a first direction of rotation. In various embodiments, gearing, including a plurality of planetary gear sets, is used to operatively connect the motor to the rocker and the tensioning wheel.
