[0024] The present invention provides a cutting mechanism for a foam cutter, including: a frame 1, a Y-axis driving device 2, an X-axis driving device 3, a Z-axis driving device 4, and a cutting tool device 5. The number of the Y-axis driving devices 2 is two groups, and the two groups of Y-axis driving devices 2 are respectively arranged on both sides of the frame 1. The X-axis driving device 3 is arranged on the Y-axis driving device 2, the Z-axis driving device 4 is arranged on the X-axis driving device 3, and the cutting tool device 5 is arranged on the Z-axis driving device 4. The cutting tool device 5 is used for cutting the foam.

[0025] It can be understood that the Y-axis driving device 2 can drive the X-axis driving device 3 to move back and forth, the X-axis driving device 3 can drive the Z-axis driving device 4 to move left and right, and the Z-axis driving device 4 can drive the cutting tool device 5 to move up and down, that is, it can drive the cutting tool device 5 to move back and forth, left and right, and up and down, so that the cutting tool device 5 can automatically and accurately move to the cutting position to cut the foam. For example, the following control method can be adopted to cut the foam: first drive the cutting tool device 5 to move above the foam, then drive the cutting tool device 5 to descend through the Z-axis driving device 4, and further drive the cutting tool device 5 to move back and forth or left and right through the Y-axis driving device 2 or the X-axis driving device 3 to cut the foam; of course, other control methods can also be adopted according to specific requirements, and no more restrictions are imposed here.

[0026] In this embodiment, the Y-axis driving device 2 includes a Y-axis slide rail, a Y-axis rack, a first motor 21, a first gear 22, and a first slide plate 23. The Y-axis rack and the Y-axis slide rail are arranged parallel to each other vertically on the side of the frame 1. The motor shaft of the first motor 21 is connected to the first gear 22, the first gear 22 meshes with the Y-axis rack, the first motor 21 is installed on the outside of the first slide plate 23, and the inside of the first slide plate 23 is slidably arranged on the Y-axis slide rail. The first motor 21 drives the first gear 22 to rotate. Since the first gear 22 meshes with the Y-axis rack, the first slide plate 23 can slide back and forth along the Y-axis slide rail. The structures of the two groups of Y-axis driving devices 2 in this embodiment are the same.

[0027] Further, the X-axis driving device 3 specifically includes a mounting bracket 31, an X-axis slide rail 32, an X-axis rack 33, a second motor 34, a second gear, and a second slide plate 35.

The motor shaft of the second motor 34 is connected to the second gear, the second gear meshes with the X-axis rack 33, and the inside of the second slide plate 35 is slidably arranged on the X-axis slide rail 32. It can be understood that the forward and backward sliding of the above two first slide plates 23 can drive the mounting bracket 31 to move forward and backward, that is, drive the entire X-axis driving device 3 to move forward and backward; in addition, the second motor 34 drives the second gear to rotate. Since the second gear meshes with the X-axis rack 33, the second slide plate 35 can slide left and right along the X-axis slide rail 32. The number of the above X-axis slide rails 32 is preferably two.

[0028] In addition, in this embodiment, the Z-axis driving device 4 includes a Z-axis mounting plate 41, a Z-axis slide rail 42, a third motor 43, and a lead screw 44.

The motor shaft of the third motor 43 is connected to the lead screw 44; the cutting tool device 5 includes a tool holder 51 and a tool head 52. The tool holder 51 is slidably arranged on the Z-axis slide rail 42 through a slider, the tool holder 51 is also threadedly connected to the lead screw 44, and the tool head 52 is arranged at the bottom of the tool holder 51. The left and right sliding of the above second slide plate 35 can drive the Z-axis mounting plate 41 to move left and right, that is, drive the entire Z-axis driving device 4 to move left and right; in addition, the third motor 43 drives the lead screw 44 to rotate. Since the lead screw 44 is threadedly connected to the tool holder 51, the cutting tool device 5 can slide up and down along the Z-axis slide rail 42. The number of the Z-axis slide rails 42 is preferably two. In addition, the cutting tool device 5 can also adopt other cutting tool structures in the prior art, and no excessive restrictions are imposed here.
