[0023] In a further preferred embodiment of the present invention, Figure 1 , 2 As shown, the trimming mechanism 8 includes: a lifting plate 9 is arranged on the top of the lifting frame 5, a connecting rod 10 is fixedly connected to the middle of the lifting plate 9, and a cutting wheel 11 is rotatably connected inside the connecting rod 10; two hydraulic cylinders 12 are arranged on both sides of the top of the lifting plate 9, and the tops of the hydraulic cylinders 12 are fixedly connected to the adjusting blocks 13, and a bidirectional screw 14 is rotatably connected to the frame 1 near the adjusting blocks 13, and the two adjusting blocks 13 are respectively threadedly connected to the outer surfaces of the two ends of the bidirectional screw 14.

The telescopic end of the hydraulic cylinder 12 drives the lifting plate 9, and the lifting plate 9 drives the connecting rod 10 and the lifting frame 5. When the positioning roller 7 moves to the laminating body 4, the telescopic end of the hydraulic cylinder 12 continues to drive the lifting plate 9 to move downward, and the lifting plate 9 drives the cutting wheel 11 through the connecting rod 10, so that the cutting wheel 11 can contact the laminating body 4.

[0025] In a further preferred embodiment of the present invention, Figure 1 , 5 As shown, one end of the bidirectional screw 14 passes through the frame 1 and extends to the handle 15 , and the handle 15 is fixedly connected to the bidirectional screw 14 .
