A second lead screw 213 is fixedly installed at the center of the second coupling 212. A second nut mounting seat 214 is threadedly connected to the outside of the second lead screw 213. When in use, the staff pre-enter the processing code of the shape to be cut into the overall control box 106. After the first motor 206 receives the control signal, it outputs the required rotational speed and torque. The power is transmitted through the first coupling 205 to drive the first lead screw 202 to rotate, thereby driving the first nut mounting seat 203 to perform a linear reciprocating motion in the front-rear direction. Under the connection and fixation of the rectangular column 211, it further drives the second motor 210, the second coupling 212, the second lead screw 213 and the second nut mounting seat 214 to complete the linear reciprocating motion in the front-rear direction. After the second motor 210 receives the corresponding rotational speed and torque signals, under the connection of the second coupling 212, it drives the second lead screw 213 to rotate, further driving the second nut mounting seat 214 to achieve a linear reciprocating motion in the left-right direction. The precise linear reciprocating motions in the front-rear direction and the left-right direction cooperate with each other, enabling the cutting assembly to precisely cut out the shape required by the sponge plate body 104, achieving the shaping and cutting effect of the sponge plate body 104. The overall structure is reliable, the operation process is stable, greatly reducing the labor intensity of manual operation. And due to the reduction of human errors, the cutting accuracy is improved, and the waste of materials is effectively controlled, thus improving the utilization efficiency of resources.

A laser cutter 303 is fixedly installed at the bottom of the fixing plate 301. A laser cutting head 304 is fixedly installed at the bottom of the laser cutter 303. The fixing plate 301 is externally threadedly connected with fixing screws 302. During use, the fixing plate 301 plays a role in connecting and fixing. The laser cutter 303 generates a high-energy laser beam through internal work. After the laser cutting head 304 receives the laser beam, it focuses it onto a tiny point. The focused laser beam irradiates the sponge board body 104. The high energy of the laser quickly heats the material of the sponge board body 104 to form a cutting line to complete the cutting work on the sponge board body 104. The overall cutting accuracy is relatively high, the operation is simple, the production efficiency is improved. Laser cutting is a non-contact cutting method, thus avoiding material deformation, improving the quality of the sponge board body 104, and enhancing durability.

When in use, the operator pre-enters the processing code of the shape to be cut into the main control box 106. After the first motor 206 receives the control signal, it outputs the required rotational speed and torque. The power is transmitted through the first coupling 205 to drive the first lead screw 202 to rotate, thereby driving the first nut mount 203 to perform a linear reciprocating motion in the front-rear direction. Under the connection and fixation of the rectangular column 211, the second motor 210, the second coupling 212, the second lead screw 213 and the second nut mount 214 are further driven to complete the linear reciprocating motion in the front-rear direction. After the second motor 210 receives the corresponding rotational speed and torque signals, under the connection of the second coupling 212, it drives the second lead screw 213 to rotate, further driving the second nut mount 214 to achieve a linear reciprocating motion in the left-right direction. The precise linear reciprocating motions in the front-rear direction and the left-right direction cooperate with each other, enabling the cutting assembly to accurately cut out the shape required by the sponge board body 104, achieving the shaping and cutting effect of the sponge board body 104. The overall structure is reliable and the operation process is stable, greatly reducing the labor intensity of manual operation. Moreover, due to the reduction of human errors, the cutting accuracy is improved, and the waste of materials is effectively controlled, thereby improving the utilization efficiency of resources. The fixing plate 301 is fixedly installed at the bottom of the second nut mount 214. The laser cutter 303 is fixedly installed at the bottom of the fixing plate 301. The laser cutting head 304 is fixedly installed at the bottom of the laser cutter 303. When in use, the fixing plate 301 plays a role of connection and fixation. The laser cutter 303 generates a high-energy laser beam through internal work. After the laser cutting head 304 receives the laser beam, it focuses it on a tiny point. The focused laser beam irradiates the sponge board body 104. The high energy of the laser quickly heats the material of the sponge board body 104 to form a cutting line to complete the cutting work of the sponge board body 104. The overall cutting accuracy is relatively high, the operation is simple, and the production efficiency is improved. Laser cutting is a non-contact cutting method, thus avoiding material deformation, improving the quality of the sponge board body 104, and enhancing its durability.
