[0023] Please refer to Figures 1-3 , the present invention provides a technical solution: a feeding mechanism of a film laminating machine and the film laminating machine, including a base 1, an adjusting mechanism and a limiting mechanism. A chassis 2 is arranged on the side of the base 1, and a support rod 3, a first conveying roller 6, a support plate 8 and a second conveying roller 7 are arranged above the base 1. The adjusting mechanism is arranged above the support plate 8.

[0024] Further, the adjusting mechanism includes a slide rail 9, a bidirectional lead screw 10, a knob 11 and a lead screw slider 12. The slide rail 9 is fixed on the support plate 8. One end of the bidirectional lead screw 10 is rotatably connected in the slide rail 9, the other end of the bidirectional lead screw 10 penetrates through the slide rail 9 and is connected to the knob 11. Two lead screw sliders 12 are symmetrically threadedly connected on the bidirectional lead screw 10, and a limiting mechanism is arranged below each lead screw slider 12; by rotating the bidirectional lead screw 10, the bidirectional lead screw 10 is used to drive the lead screw sliders 12 to move relative to each other, so as to realize the adjustment of the distance between the limiting mechanisms.

[0025] Further, the limiting mechanism includes a vertical lead screw 13, an adjusting block 15, a suspension rod 16, a connecting plate 17 and a limiting roller 18. The vertical lead screw 13 is fixed on the lead screw slider 12, the adjusting block 15 is threadedly connected to the vertical lead screw 13, the suspension rod 16 is fixed on the adjusting block 15, the connecting plate 17 is fixed at the end of the suspension rod 16, and the limiting roller 18 is rotatably connected to the connecting plate 17. The two sides of the film are limited by the limiting roller 18 to prevent the film from shifting during transportation, and the height of the limiting roller 18 can be adjusted by rotating the adjusting block 15.

[0026] Further, an installation roller 4 is arranged on the support rod 3, and a film roll 5 is arranged on the installation roller 4. The film is conveyed by a first conveying roller 6 and a second conveying roller 7.

[0032] In summary, when the present device is in use, the film on the film roll 5 passes above the first conveying roller 6, then passes between the limiting rollers 18 in the limiting mechanism, and then passes below the second conveying roller 7 for conveyance. During this process, since the two sides of the film are limited by the limiting rollers 18, the position of the film can be effectively prevented from shifting. When it is necessary to adjust the distance between the limiting mechanisms, only need to rotate the knob 11 to drive the bidirectional lead screw 10 to rotate, use the bidirectional lead screw 10 to drive the two lead screw sliders 12 to move relative to each other, and use the lead screw sliders 12 to drive the limiting mechanisms to move, so as to adjust the distance between the limiting mechanisms. The height of the limiting roller 18 can also be adjusted by rotating the adjusting block 15, so that the adjusting block 15 moves on the vertical lead screw 13, the adjusting block 15 drives the suspension rod 16 to move, the suspension rod 16 drives the connecting plate 17 and the limiting roller 18 to move, so as to adjust the height of the limiting roller 18.
