Abstract

A machine core of a packing machine includes a packing strap ironing adhering and strap cutting mechanism, an ironing adhering sliding board mechanism, and a control mechanism. The machine core is further provided with a strap feeding and returning and strap tightening device. The strap feeding and returning and strap tightening device includes a drive roller (3), a first driven roller (1), and a second driven roller (2). According to the entry direction of a packing strap, the first driven roller (1) is located down-stream from the second driven roller (2). The first driven roller (1) and the second driven roller (2) are respectively arranged eccentrically. The first driven roller (1) and the drive roller (3) are always in contact with one another and cooperate for feeding and returning the strap. The second driven roller (2) is a movable roller, and is controlled by the control mechanism to move to a first matching state with the drive roller (3) and to move out of the first matching state with the drive roller (3). The first matching state is the state in which the second driven roller (2) and the drive roller (3) are in contact with and cooperating with one another for tightening the strap. The machine core of the packing machine has a simple structure, can enable movement of simultaneous strap returning and tightening, thereby reducing failure rate, and achieving good packing.
