In one embodiment: the buffer device 5 is a balance cylinder, when the air pressure of the balance cylinder is controlled to be P1 in the empty load state, the gravity of the sliding plate box 21 is slightly larger than the supporting force of the balance cylinder, and the difference value of the gravity and the supporting force is maintained at a constant value, so that the screw rod is jointed with the sliding plate box 21, and the clearance is eliminated. When the load state is carried out, the air pressure of the balance cylinder is increased to be P2, so that the sum of the gravity of the slide plate box 21 and the piece 7 to be cut is slightly larger than the supporting force of the balance cylinder, and the difference value of the gravity and the gravity is maintained to be a constant value. When the state is cutting, the piece 7 to be cut is then subjected to tension in the wire web upwards, which can be detected by the load cell. The supporting force provided by the balancing cylinder needs to be dynamically adjusted in real time at the moment, so that the sum of the weights of the sliding plate box 21 and the piece 7 to be cut is ensured to be slightly larger than the sum of the supporting force of the balancing cylinder and the tension of the wire mesh. Alternatively, the supporting force of the balancing cylinder may be adjusted stepwise in the cutting state, for example, the supporting force is reduced by a preset force value every time a preset distance is fed. Therefore, along with the progress of cutting, the gravity of the slide plate box 21 is certain, and the gravity of the cutting material is reduced along with the progress of cutting, and the acting force through the air cylinder is changed at the moment, so that under the same wire mesh tension, the difference value between the supporting force of the air cylinder and the sum of the gravity of the slide plate box 21 and the gravity of the piece 7 to be cut is kept in a certain preset interval, the load cell works stably, and the deviation of the detection value of the load cell is avoided.
