A ball screw 17 is fixedly connected to one side of the bevel gear 16. The outer periphery of the ball screw 17 is threadedly connected to a threaded sleeve 8. By setting the power motor 13, the bevel gear 15 is driven to rotate by the power motor 13. At the same time, the ball screw 17 is driven to rotate by the bevel gear 15, and then the cutting wire cuts the foam, so that the production efficiency is significantly improved and the product quality is more stable.

[0027] Among them, two guide rails 18 are fixedly connected to the surface of the workbench 1. Two clamping plates 19 are slidably connected to the outer peripheries of the two guide rails 18. A servo motor 20 is bolted to the lower part of the central end of the workbench 1. By setting the clamping plates 19, it is ensured that the foam will not deviate during cutting, and the clamping plates 19 can also be adjusted to ensure that they are suitable for foam boards of different sizes.

[0028] Among them, the output end of the servo motor 20 passes through the workbench 1 and is drivingly connected to a turntable 21. A storage groove 22 is formed on the surface of the turntable 21. A limit pin 23 is rotatably connected to the inside of the storage groove 22.

[0032] Working principle: When in use, first place the foam to be cut on the surface of the workbench 1, then limit the foam by moving two clamping plates 19. Start the power motor 13, the power motor 13 drives the rotating shaft 14 to rotate, the rotating shaft 14 drives the bevel gear 15 to rotate, the bevel gear 15 drives the cone gear 16 to rotate, and at the same time drives the ball screw 17 to rotate, so that the moving frame 2 moves horizontally on the horizontal slide rail. Start the drive motor 3, the output end of the drive motor 3 drives the rotating shaft 4 to rotate, and at the same time drives the driving wheels 5 at both ends to rotate. The driving wheels 5 drive the driven wheels 7 to rotate through the toothed belt 6, and at the same time drive the limiting plate 11 fixed on the surface of the toothed belt 6 to move. Then let the slider 10 change in the vertical direction along the cylinder 9, and finally realize the change in the height direction of the cutting wire 12. By starting the servo motor 20, the servo motor 20 drives the turntable 21 to rotate. The limiting pins 23 on the surface of the turntable 21 can be stored in the storage groove 22 when not in use. The limiting pins 23 can fix the foam to prevent deviation, so as to achieve the purpose of cutting foams of different shapes. The waste bin 25 can collect the foam generated during cutting. The dust and foam chips can be extracted and collected through the dust suction box 24, which can avoid the flying of foam chips in the factory building and polluting the environment. It enters the inside of the dust removal box 26 through the telescopic hose 27.
