It also includes cleaning mechanisms 5 respectively installed at the upper and lower ends of the two sets of composite rollers 4. A set of adjustment mechanisms 7 are fixedly connected to the rear end of the top surface of the frame 1 through a support table 6.

[0039] Specifically, the adjustment mechanism 7 can compact and position the laser film to avoid wrinkles. The laser film can pass between the two sets of composite rollers 4 and be exported by the export frame 2. The cleaning mechanism 5 can clean the outer side of the composite rollers 4 to keep the outer side of the composite rollers 4 clean.

The bottom end of the first moving plate 75 is provided with a positioning mechanism 76.

[0045] Specifically, when the screw rod 73 rotates, it can move back and forth at the top rear end of the third connecting plate 72 and drive the connecting rod 74 to move synchronously, thereby driving the first moving plate 75 to move. When the first moving plate 75 moves, it can drive the guide rod 763 to move through the guiding groove 751, thereby driving the second moving plate 762 to move, and uniformly adjusting the second moving plate 762.

And no less than two positioning wheels 764 are installed at the bottom ends of the second moving plates 762.

[0047] Specifically, when the first moving plate 75 moves, it can drive the guide rod 763 and the second moving plate 762 to move through the guide groove 751, so that the second moving plate 762 moves horizontally along the guide rod 761, and the distance between two adjacent second moving plates 762 is adjusted. The synchronous adjustment of the distance between two adjacent second moving plates 762 can be realized, the adjustment speed can be improved, and the laser film can be easily compacted and positioned by the positioning wheel 764, avoiding phenomena such as wrinkles in the laser film and ensuring the normal production of the laser film.
