Then, the conveying module 3 continues to drive the clamping device 310 to move away from the feeding module, pulls the end of the packaging film to move forward, and pulls out a certain length of packaging film to cover the upper surface of the bottom of the working platform.

file into:

As shown in FIGS. 6-7 , through the program setting of the automatic control system or the manual command input of the user interaction module, the automatic control system controls the rotation of the lift motor 402 , and the lift motor 402 drives the screw 405 Rotating, the screw 405 drives the edge banding knife 401 to descend to the worktable 101 , and the edge banding function of the edge banding knife 401 is turned off at this time.

The document is put into the document inlet on the top of the edge-sealing knife of the edge-sealing device, and is stacked on the worktable 101 covered with the packaging film through the cavity of the edge-sealing knife. After the document falls on the worktable 101 , a control command is input through the user interaction module, the lifting motor 402 is rotated to make the edge banding knife 401 rise, and the edge banding knife is returned to the upper end of the bracket 102 .

Packaging film folding and edge sealing:

As shown in FIG. 8 , the conveying motor 301 continues to rotate in the same direction, so that the clamping device 310 bypasses the sprocket 302 and turns over to the upper side of the conveyor belt 303 , and then the clamping device 310 moves toward the feeding module 2 .

As shown in FIG. 9 , the elevating motor 402 drives the screw 405 to rotate, and drives the edge-sealing knife 401 of the edge-sealing device to lower and compress the packaging film. At this time, the edge-sealing function of the edge-sealing knife 401 is turned on. At least three edges of the packaging film are edge-sealed and the packaging film is cut. In order to prevent the document from moving during edge sealing, the pressing plate 404 can be used to press the document. Preferably, before the edge sealing knife 401 is lowered for edge sealing, the turning motor rotates to drive the pressing plate 404 downward. Rotate and hold down the document and packaging film.

Unloading, storage and reset:

After the edge sealing is completed, the turning motor rotates to drive the pressing plate 404 to turn up and return to the original position. Subsequently, the edge banding knife 401 rises and resets. The automatic control system controls the rotation of the unloading roller 501, thereby driving the unloading belt 502 to rotate to send the packaged documents to the unloading port 503, and the unloading port 503 is controlled to open through the unloading plate . The packaged documents are discharged from the discharge port 503 and fall into the storage drawer 504 . The conveying motor 301 continues to rotate, and drives the clamping device 310 to return to the lower side of the sprocket 302 at the feeding end of the conveying module 3 for the next edge sealing. When the storage capacity of the storage drawer 504 reaches a predetermined position, the limit alarm 13.2 gives an alarm and stops the file packaging.
