Abstract:
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.
