The rotating mechanism includes a support frame, a worm gear reducer 135 and a driving motor. The action output shaft of the worm gear reducer is connected to the rotating shaft of the second U-shaped frame 132. The driving motor drives the worm gear reducer 135 to rotate, thereby driving the second U-shaped frame 132 to rotate. At the same time, the worm gear reducer has a self-locking function to prevent the second U-shaped frame 132 from being deflected by external force during operation, and the working process is stable and reliable.

[0033] Preferably, in an automatic wrapping packaging machine of this embodiment, the lifting mechanism 11 includes a first driving device 111 and a slider 112.

After one rotation, the wrapping film can be firmly wrapped around the outer surface of the product, and the clamping jaw 136 is loosened.

[0035] Preferably, in an automatic wrapping packaging machine of this embodiment, the film-scalding mechanism 134 includes a heating wire 1341 and a swing arm mechanism. The swing arm mechanism includes a Z-shaped rocker arm rotatably arranged on the second U-shaped frame 132 and a driving cylinder driving the Z-shaped rocker arm to swing, one end of the driving cylinder is hinged to a hinge seat on the second U-shaped frame 132, and the other end is hinged to the Z-shaped rocker arm, and a bracket is connected to the end of the Z-shaped rocker arm.

[0037] When using the utility model, the height and angle of the film clamping and hot stamping assembly 13 can be adjusted according to actual needs, such as for products with a truncated cone profile. By controlling the first driving device 111 of the lifting mechanism 11, the lifting and lowering movement of the film clamping and hot stamping assembly 13 on the column 10 can be realized; by controlling the driving motor of the rotating mechanism, the rotation adjustment of the film clamping and hot stamping assembly 13 within a certain angle range can be realized. In this way, automatic wrapping and packaging operations can be realized from different heights and angles, which improves the flexibility and efficiency of the packaging operation.
