[0037] Example 2

[0038] Reference Figures 5-6 A foam box cutting device, the adjusting mechanism includes a second fixed plate 13, a rotating rod 14, a rotating gear 15, a moving rack 16 and a clamping plate 17. The second fixed plate 13 is fixed on both sides of the base plate 1. The rotating rod 14 is rotatably connected to the inner side of one side of the second fixed plate 13. The rotating gear 15 is fixed to the outer side of the rotating rod 14. The moving rack 16 is meshed with the bottom of the rotating gear 15. The moving rack 16 is slidably connected to the base plate 1 and the second fixed plate 13. The clamping plate 17 is fixed to one side of the moving rack 16 and is slidably connected to the base plate 1.

[0039] The adjustment mechanism also includes a clamping plate 17, a worm gear 18, a worm 19 and a knob 20.

[0040] The adjustable mechanism allows for precise positioning of the foam box on the base plate 1, resulting in more accurate cutting of the foam box.

[0041] Both ends of the bottom of the clamping plate 17 are fixed with I-shaped guide plates 21. The I-shaped guide plates 21 are located inside the base plate 1 and are slidably connected to the base plate 1. The design of the I-shaped guide plates 21 guides the movement of the clamping plate 17.

[0042] A connecting reinforcing plate 22 is fixed to the bottom of the second fixed plate 13. The connecting reinforcing plate 22 is fixedly connected to the base plate 1 and provides support for the second fixed plate 13.

[0043] The usage process of the foam box cutting device provided by this utility model is as follows: When it is necessary to cut the foam box, place the foam box on the base plate 1, and mark the position to be cut on the foam box.

[0044] Then rotate the knob 20. Since the knob 20 is fixedly connected to the worm gear 19, and the worm gear 19 is meshed with the worm wheel 18, the rotation of the knob 20 drives the worm wheel 18 to rotate, which in turn causes the rotating rod 14, which is fixedly connected to the worm wheel 18, to rotate as well. The rotating rod 14 is fixedly connected to the rotating gear 15, and the rotating gear 15 is meshed with the moving rack 16. Thus, the rotation of the knob 20 drives the moving rack 16 to move through the rotating gear 15, which causes the clamping plate 17, which is fixedly connected to the moving rack 16, to move on the top of the base plate 1. This causes the clamping plates 17 on both sides to contact the foam box simultaneously. By adjusting the knobs 20 on both sides, the horizontal marking line on the foam box is positioned at the bottom of the heating wire 4.

[0045] Since the first fixed motor 6 is equipped with a 5G Bluetooth module, the first fixed motor 6 is started by an external controller. The output end of the first fixed motor 6 drives the first bevel gear 7 to move. The first bevel gear 7 meshes with the second bevel gear 8. The second bevel gear 8 is fixedly connected to the transmission rod 9. Thus, the rotation of the first bevel gear 7 drives the two third bevel gears 10 fixed to the transmission rod 9 to rotate. Since the third bevel gear 10 meshes with the fourth bevel gear 11, and the fourth bevel gear 11 is fixedly connected to the lead screw 12, which is threadedly connected to the sliding plate 3, the rotation of the first bevel gear 7 drives the heating wire 4 fixed to the sliding plate 3 to move to the top through the lead screw 12 and the sliding plate 3. At this time, the heating wire 4 is energized to cut the foam box.
