The use process comprises the following steps:

when the box 610 is subjected to film wrapping operation, the Y-direction linear module 211 of the feeding assembly 200 drives the clamping piece 210 and the box 610 below the clamping piece 210 to move from the back direction to the front direction, which is close to the center of the rotating frame 110, and then the Z-direction linear module 212 is utilized to realize the effect that the clamping piece 210 drives the box 610 to move downwards to the rotating frame 110 until the box 610 is stably located on the rotating frame 110. In the process of moving the box 610 downward, the inner wall of the lower opening of the box 610 is fitted outside the guide block 130, and the box 610 falls to a desired position on the rotating frame 110 under the guide of the guide part 131. Then, the second Y-direction cylinder 121 drives the pressing member 120 to move outward until the pressing member 120 abuts against the inner wall of the box 610, so that effective clamping with the box 610 is realized, and the box 610 is prevented from generating local displacement on the rotating frame 110.

Then, the film clamping rod 410 of the film supply assembly 400 pulls the end edge of the packaging film 620 from the film supply roller 300, the film clamping rod 410 pulls the packaging film 620 to the middle position of the side wall of the box 610 along the X direction, and then moves for a certain displacement along the Y direction to the direction close to the side wall of the box 610, at this time, the rubber rollers 520 of the two pressing assemblies 500 are both positioned at the outer side of the packaging film 620 before the rotating frame 110 rotates, and then the rotating frame 110 drives the pressing assemblies 500 and the box 610 to rotate counterclockwise. After the rotating frame 110 rotates a circle, the rubber roller 520 far away from the film supplying roller 300 moves to a side far away from the box 610 for a positioning movement and then moves downwards to avoid the wrapping of the outer layer of the packaging film 620, after the rotating frame 110 continues to rotate a certain angle and crosses the position of the rubber roller 520 corresponding to the outer side of the box 610, the rubber roller 520 located below moves upwards and approaches to the box 610 and is pressed on the outer side of the outer layer of the packaging film 620, the other rubber roller 520 located inside the packaging film 620 moves to a side far away from the box 610 and then moves downwards to avoid the packaging film 620, the other rubber roller moves upwards and approaches to the box 610 and is pressed on the outer side of the outer layer of the packaging film 620, the rotating frame 110 continues to rotate to complete the wrapping of the second layer of the film, the action that the rubber roller 520 moves downwards to avoid the wrapping of the packaging film 620 is repeated, then the rubber roller 520 presses on the outer side of the second layer of the packaging film 620, the cutting knife 420 moves to the, the rubber roller 520 close to one side of the cutting knife 420 moves to one side far away from the box 610 and then moves to one side close to the film supply roller 300, and moves to one side close to the box 610 to the outer side of the outer packaging film 620, and then moves to one side far away from the film supply roller 300 to flatten the tail end of the packaging film 620 outside the box 610, so that the film wrapping process is completed.

Finally, the clamping member 210 of the feeding assembly 200 moves downwards, the two clamping handles respectively clamp one box 610 to be wrapped with a film and the box 610 wrapped with the film on the rotating frame 110 and then move upwards, the box 610 to be wrapped with the film is placed on the rotating frame 110 to be wrapped with the film after moving along the Y direction, and at the moment, the box 610 wrapped with the film is synchronously moved to a downward moving station to perform subsequent operations.

The present invention is not limited to the above preferred embodiments, and any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
