[0030] See also Figure 1-Figure 9 The present invention provides two technical solutions, which specifically include the following embodiments:

[0031] Example 1: Reference Figure 1-Figure 9 An automatic cutting device for sponge production and processing includes a machine body 1, a conveyor belt 2 is rotatably connected inside the machine body 1, and is used to transport a sponge board body 3. A positioning plate 9 is fixed above the machine body 1, and a right-angle transmission frame 10 is slidably installed inside the positioning plate 9. The right-angle transmission frame 10 is used to move synchronously with the sponge board body 3; a middle slide 11 is slidably connected to the right-angle transmission frame 10, and a laser cutting device 12 is slidably installed at the bottom of the middle slide 11. The laser cutting device 12 can translate with the right-angle transmission frame 10, keep synchronization with the transported sponge board body 3 and perform cutting operations. The laser cutting device 12 is an existing device and is used to transport the sponge board body 3. The sponge board body 3 is cut by the laser cutting device 12. When the sponge board body 3 is being transported, when the cutting position of the sponge board body 3 reaches directly below the laser cutting device 12, the right-angle transmission frame 10 can drive the middle slide 11 and the laser cutting device 12 to move, and keep the same speed as the sponge board body 3. At this time, as the middle slide 11 slides downward, the laser cutting device 12 can contact with the sponge board body 3, and the cutting operation is completed by the translation of the laser cutting device 12. After the cutting is completed, the laser cutting device 12 is reset upward, and the right-angle transmission frame 10 drives the laser cutting device 12 to reset and then perform a secondary cutting operation, which ensures the continuity of the operation and effectively improves the operation efficiency of the equipment.

[0032] A bottom pressure plate 14 is provided at the bottom of the middle slide 11, and a plurality of limit slide bars 13 are fixed on the top surface of the bottom pressure plate 14.
