The height of the blade 402 exceeds the film pressing support 501 and extends to the other side of the film pressing support 501. When the rodless cylinder 401 is started, the moving body 405 can drive the blade 402 to move along the length direction of the film pressing support 501.

[0056] Working process:

[0057] Place the film roll on the motorized roller 204 and the unpowered roller 203. Limit the axial displacement of the film roll by the film roll fixing sleeve 205. Lead the film out of the film roll and pass through the film guide roller 3 and the film pressing plate 505 and the film pressing support 501 in sequence. Finally, the film reaches the film clamping assembly 24 under the cantilever 23.

[0058] The cross beam 12 is initially positioned at the bottom of the column 6, and the cantilever 23 is initially positioned close to the column 6 to facilitate the film clamping of the film clamping assembly 24. The film clamping cylinder 2405 of the film clamping assembly 24 is in an extended state, and the film clamping plate 2403 is separated from the vertical part 2407, waiting for clamping of the film. After the cross beam 12 and the cantilever 23 are both positioned at the initial positions, the film is introduced between the film clamping plate 2403 and the vertical part 2407, and then the film clamping cylinder 2405 is retracted to clamp the film.

[0059] After the film clamping assembly 24 clamps the film, the motor 2 is started to vertically move the cross beam 12 upward, and at the same time, the motor roller 204 is rotated to unroll the film, and the film clamping assembly 24 vertically moves upward while clamping the film.

[0060] When the cross beam 12 is vertically moved to a suitable height (the standard of the suitable height is that the unrolled film can completely cover the top of the goods), the film pressing cylinder 504 is extended to drive the film pressing rod 503 to rotate and drive the film pressing plate 505 to move toward the film pressing support 501 until the film pressing plate 505 is parallel to and in contact with the film pressing support 501, the rubber 502 provides elastic pressing force to tightly clamp the film between the film pressing plate 505 and the film pressing support 501, at this time, the film is pressed onto the blade edge of the blade 402, the rodless cylinder 401 is started to push the mounting plate 404 to slide along the length direction of the film pressing support 501, the blade 402 moves with the mounting plate 404, and cuts the tightly pressed film. After the film is cut, the blade 402 returns to the original position.

[0061] After the film is cut, the motor 1 is started to move the cantilever 23 along the cross beam 12 to a suitable position, the film clamping cylinder 2405 is extended to release the film, the film is covered on the top of the goods, and then the goods with the film on the top are forwarded. The motor 1 and the motor 2 are reversed to return the cantilever 23 and the cross beam 12 to the initial positions, and the next cycle is started.

[0062] The above description of the disclosed embodiments enables one of ordinary skill in the art to make or use the present application. Various modifications to these embodiments will be readily apparent to those of ordinary skill in the art, and the generic principles defined herein can be applied to other embodiments without departing from the spirit or scope of the application.
