Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
The applicant finds out through practical operation that: the existing tray type winding machine is used for accumulating materials on a rotary table of the winding machine, the accumulated volume is large, the height is high, then a driving device for driving the rotary table to rotate is started, and a lifting assembly on a stand column is combined to regulate and control a film fixing shaft to move up and down to achieve the wrapping effect when the rotary table rotates. In the above process, the preferred turntable is used for carrying not only the articles but also the roller conveying line, so that the load of the turntable is extremely large, and the requirement on the driving device is extremely high and power is consumed when the turntable rotates on the basis. In addition, when the turntable starts to rotate, articles are only stacked on the turntable and are not bound by any external force, so that the articles are easy to slip off and scatter, and are required to be stacked again, which is time-consuming and labor-consuming.
In view of the above problems, the applicant believes that the same effect can be achieved without a transposition thinking that the film fixing shaft moves up and down and simultaneously moves circularly around the object, and the problem is solved.
