A film clamping working position of the film clamping device is in front of an upright post when the M-shaped turntable turns to the angle of the original position. The M-shaped winding machine is also provided with a storage battery charging connection device. When the M-shaped turntable turns to the angle of a charging position, a turntable upper part and a turntable outer part of the charging connection device can be electrically connected. A driving electric motor of a film frame lifting device, the driving electric motor of the M-shaped turntable, and the power devices in the automatic film cutting device and the film lifting device are controlled by the main controller. The M-shaped winding machine can realize automatic film clamping and fully automatic film winding.

The present invention provides a central shaft mechanism, which is arranged on the base of a winding machine, including a central shaft component, a central shaft is arranged in the central part of the central shaft component, the central shaft component is also provided with a bearing support structure and a plurality of first limiting structures, and the central shaft component is fixed and limited in the base of the winding machine through the first limiting structures. The central shaft mechanism of the present invention has stable position, stable and reliable operation, and can reduce the working noise and noise during operation. In addition, it can be packed separately from the base during transportation, and can be quickly installed on site, which can not only provide more stable support, but also reduce the height of the turntable of the height winding 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.
