Each of the limit plates is installed between the receiving plate and the first mounting frame by a pair of second bolts.

[0019] By adopting the above technical solution, the beneficial effects of the utility model are as follows:

[0020] Since the follow-up packaging device of the laparoscopic sticker includes a traction die-cutting knife seat, a follow-up packaging mechanism and a cutting knife seat, when the laparoscopic sticker is packaged, the laparoscopic sticker first passes through the traction die-cutting knife seat. In this process, the laparoscopic sticker and the bottom film pass between the first traction roller and the second traction roller, thereby completing the lamination of the bottom film. After laminating the bottom film, the laparoscopic sticker passes between the die-cutting bottom roller and the die-cutting roller, thereby completing the die-cutting of the shape of the laparoscopic sticker. After the die-cutting of the shape is completed, the laparoscopic sticker enters the upper packaging film and the lower packaging film, passes through the follow-up packaging mechanism after being pressed by the pressing plate. In this process, driven by the packaging cylinder, the upper packaging template moves toward the direction close to the laparoscopic sticker, and reciprocates in the vertical direction, driving the rotating shaft driving motor. The lower packaging template moves toward the direction close to the laparoscopic patch, thus completing the packaging of the laparoscopic patch in a section. During this process, the follower frame moves along the moving direction of the laparoscopic patch under the drive of the lead screw drive motor. After the laparoscopic patch in a section is packaged, the follower frame moves to the unpackaged area under the drive of the lead screw drive motor to continue packaging the laparoscopic patch. This reciprocating process can complete the packaging of all laparoscopic patches, and the packaged laparoscopic patches enter the cutting knife seat for cutting. In the utility model, during the packaging process of the laparoscopic patch, the follower frame moves along with the movement of the laparoscopic patch, thereby realizing the follow-up packaging of the laparoscopic patch, so that the laparoscopic patch does not need to move forward intermittently, thereby improving the production efficiency of the laparoscopic patch.

[0021] Since the laparotomy sticker follow-up packaging device includes a traction die-cutting knife seat, and the traction die-cutting knife seat is provided with an adjustable traction component and a die-cutting component, the traction die-cutting knife seat realizes the combination of traction and die-cutting functions, shortens the distance between the traction and die-cutting processes, and thus reduces the space area occupied by the device. In the utility model, the setting of the adjustable traction component not only realizes the traction function, but also realizes the pressing of the laparotomy sticker and the bottom mold. The setting of the adjustment component makes the distance between the first traction roller and the second traction roller adjustable, so as to adapt to the material strips of different thicknesses, and improves the application scope of the device. The setting of the limiting groove and the limiting block is used to limit the rotation angle of the adjustment plate, so as to avoid the gears on the first traction roller and the second traction roller from being disengaged and the gear teeth from being broken. The setting of the limiting bolt can further limit the rotation angle of the adjustment plate, so as to adapt to the meshing conditions of gears of different models. The setting of the mounting plate means that when the first traction roller needs to be replaced, it is only necessary to remove the mounting plate, and there is no need to remove all the adjustment components, so that the replacement of the first traction roller is more convenient.

[0022] The material receiving assembly includes an upper support frame and a lower support frame installed on the material receiving plate. The upper support frame is used for supporting and guiding the upper packaging film, and the lower support frame is used for supporting and guiding the lower packaging film. The cut lap-cut sticker passes through between the die-cutting bottom roller and the die-cutting roller, and then enters between the upper packaging film and the lower packaging film. With the traction of the upper packaging film and the lower packaging film, the upper packaging film, the lap-cut sticker and the lower packaging film move between the pressing plate and the material receiving plate, and enter the next process after being pressed by the material receiving plate and the pressing plate. The setting of the pressing plate and the material receiving plate makes the upper packaging film, the lap-cut sticker and the lower packaging film fit better. The setting of the guide inclined plate is used for guiding the lower packaging film to avoid scratches on the lower packaging film by the first mounting frame.

[0023] Since the laparotomy patch follow-up packaging device includes a cutting knife seat, a stabilizing traction assembly is provided upstream of the cutting knife seat, and the first stabilizing traction roller is connected to the fourth driving mechanism by a gear transmission, so that when the stabilizing traction assembly is installed on the cutting knife seat, the fourth driving mechanism will not interfere with the cutting knife seat, thereby making the installation positions of the first stabilizing traction roller and the second stabilizing traction roller closer to the cutting bottom roller and the cutting roller, thereby making the laparotomy patch more stable during cutting.
