[0030] Please refer to Figures 1 to 6, the present utility model discloses an on-line film laminating device 10 for PETG high-gloss film. The on-line film laminating device 10 for PETG high-gloss film includes a frame 100, an unwinding mechanism 200, a roller pressing mechanism 300 and a winding mechanism 400. The unwinding mechanism 200, the roller pressing mechanism 300 and the winding mechanism 400 are all installed on the frame 100. The PETG high-gloss film coil is sleeved on the unwinding mechanism 200. The free end of the PETG high-gloss film is roller pressed by the roller pressing mechanism 300, and then is wound by the winding mechanism 400 to complete winding. The on-line film laminating device 10 for PETG high-gloss film further includes a cutting mechanism 500. The cutting mechanism 500 is installed on the frame 100 and is arranged between the roller pressing mechanism 300 and the unwinding mechanism 200. The free end of the PETG high-gloss film coil is connected to the winding mechanism 400 through the cutting mechanism 500 after being roller pressed by the roller pressing mechanism 300. When the winding mechanism 400 winds a preset length of PETG high-gloss film, the cutting mechanism 500 cuts the PETG high-gloss film to complete the on-line film laminating process of the PETG high-gloss film. Specifically, the cutting mechanism 500 includes a cutting roller 510, a rotating shaft group 520 and a driving unit 530. The rotating shaft group 520 is respectively rotatably installed on both sides of the frame 100. The two ends of the cutting roller 510 are respectively correspondingly connected to the rotating shaft group 520, so that the cutting roller 510 can rotate relative to the frame 100. The driving unit 530 is installed on one side of the frame 100 corresponding to the rotating shaft group 520. And the output end of the driving unit 530 is drivingly connected to the rotating shaft group 520. Thus, the driving unit 530 can drive the cutting roller 510 to rotate relative to the frame 100 through the rotating shaft group 520. Among them, the cutting roller 510 is set as a deformable roller body with a straight notch a on its side surface. And the cutting roller 510 is provided with a support assembly. The straight notch a extends from one end of the cutting roller 510 to the other end. A cutter 511 is arranged on one side wall of the straight notch a. One end of the support assembly is arranged inside the cutting roller 510. Thus, when the roller pressing mechanism 300 completes the roller pressing process of the PETG high-gloss film with a preset length, the support assembly can support the cutting roller 510 to deform from the inside of the cutting roller 510. At this time, the cutter 511 on one side of the straight notch a swings outwards to cut the PETG high-gloss film wound on the surface of the cutting roller 510, so as to complete the on-line film laminating process of the PETG high-gloss film. The on-line film laminating device 10 for PETG high-gloss film of the present utility model effectively improves the production efficiency, effectively reduces the labor cost, and simultaneously improves the cutting accuracy of the PETG high-gloss film through the automatic unwinding and winding, automatic roller pressing and automatic cutting of the PETG high-gloss film. In one embodiment, both the unwinding mechanism 200 and the winding mechanism 400 are set as air expanding shafts.

[0031] Further, the support assembly includes a support shaft 512, a plurality of linkage units, and a plurality of connecting rods 513. The support shaft 512 is disposed between the rotating shaft groups 520. Moreover, both ends of the support shaft 512 are respectively connected to the rotating shaft groups 520 on both sides; a plurality of linkage units are disposed on the side surface of the support shaft 512; a plurality of connecting rods 513 are respectively disposed on the inner wall surface of the cutting roller 510 along the length extension direction of the cutting roller 510; the end of each linkage unit away from the support shaft 512 is correspondingly connected to a plurality of connecting rods 513. Thus, when the rotating shaft group 520 drives the support shaft 512 to axially move, the plurality of linkage units respectively drive the plurality of connecting rods 513 to expand outward, so that the cutting roller 510 expands outward along the straight notch a, and further enables the cutter 511 to cut the PETG high-gloss film. Specifically, each linkage unit includes a first connection block 514, a plurality of linkage rods 515, and a plurality of second connection blocks 516. The first connection block 514 is connected to the side surface of the support shaft 512. The plurality of linkage rods 515 are radially disposed on the side surface of the first connection block 514. Moreover, one end of each linkage rod 515 facing the first connection block 514 is hinged to the surface of the first connection block 514, and one end of each linkage rod 515 facing away from the first connection block 514 is hinged to a second connection block 516; the plurality of second connection blocks 516 are respectively correspondingly connected to the plurality of connecting rods 513. Thus, when the support shaft 512 moves laterally, the plurality of linkage rods 515 swing in a direction away from the support shaft 512, and then drive the plurality of connecting rods 513 to deform outward from the inside of the cutting roller 510, thereby promoting the expansion of the straight notch a, and further enabling the cutter 511 to swing and cut off the PETG high-gloss film.

[0032] Further, the support assembly further includes a driving cylinder 517 and a driving seat 518. The driving cylinder 517 is disposed at the other end of the frame 100 relative to the driving unit 530. The output end of the driving cylinder 517 is connected to the driving seat 518, and the driving seat 518 is connected to the corresponding rotating shaft group 520. Thus, the driving cylinder 517 can drive the rotating shaft group 520 to axially move relative to the cutting roller 510 through the driving seat 518, and then drive the support shaft 512 and a plurality of linkage units to realize the internal support of the cutting roller 510.

[0033] Further, the rotating shaft group 520 includes two rotating shafts 521 and two buffer members 522. The opposite ends of the two rotating shafts 521 are respectively rotatably connected to the frame 100, and the two buffer members 522 are respectively disposed in cooperation between the corresponding rotating shafts 521 and the frame 100. After the cutting roller 510 completes the cutting work, the driving cylinder 517 drives the driving seat 518 to reset. During this process, the two rotating shafts 521 complete the driving reset through the corresponding buffer members 522.

[0034] Furthermore, the rolling mechanism 300 includes two molding rollers 310 which are arranged in cooperation. Moreover, both ends of each molding roller 310 are respectively connected to the frame 100 correspondingly, so that the two molding rollers 310 can rotate collaboratively under the drive of a motor to perform an on-line film pressing process on the PETG high-gloss film.

[0035] In summary, the on-line film pressing device for PETG high-gloss film disclosed by the present utility model can cut the PETG high-gloss film through a cutting mechanism to complete the on-line film pressing process of the PETG high-gloss film. The cutting roller is set as a deformable roller body with straight notches on the side surface. In addition, the cutting roller is provided with a support assembly. The straight notches extend from one end of the cutting roller to the other end. A cutter is arranged on one side wall of the straight notch. One end of the support assembly is arranged inside the cutting roller. Thus, when the rolling mechanism completes the rolling process of the PETG high-gloss film with a preset length, the support assembly can support the deformation of the cutting roller from inside the cutting roller. At this time, the cutter on one side of the straight notch swings outwards to cut the PETG high-gloss film wound around the surface of the cutting roller, thereby completing the on-line film pressing process of the PETG high-gloss film. The on-line film pressing device for PETG high-gloss film of the present utility model effectively improves the production efficiency, effectively reduces the labor cost, and simultaneously improves the cutting accuracy of the PETG high-gloss film through the automatic rewinding and unreeling, automatic rolling, and automatic cutting of the PETG high-gloss film.

For the sake of concise description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0037] The above-described embodiments only represent several implementation manners of the present utility model. The description is relatively specific and detailed, but it cannot be understood as a limitation to the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model.
