Background

When the cloth is cut, the cloth is required to be smooth and has no folds, the shape of the cut cloth can be ensured to meet the cutting requirement, and the cut cloth piece is ensured not to be separated from the cloth. Because the cutter for cutting cloth has high working frequency and high working precision, the cut cloth piece is easy to contact with the cutter and damage the cutter after being separated. Therefore, when the cloth is sewn, the cloth is paved on a platform, the cloth is fixed, the cloth is kept flat and has no wrinkles, and the cut cloth piece can be fixed, so that the cloth can be cut. The common mode of fixed cloth has the mode of vacuum adsorption, sets up a plurality of negative pressure holes on the platform, adopts the vacuum pump to be connected with the negative pressure hole, makes the negative pressure hole form the negative pressure to adsorb fixedly to the cloth.

However, in one aspect, the fixing manner of the negative pressure adsorption requires continuous operation of the vacuum pump, which is high in energy consumption, resulting in a problem of high production cost. On the other hand, when cutting a multi-layer cloth, it is difficult to fix the cloth on the upper layer by negative pressure suction. The effect of negative pressure adsorption is affected by the air permeability of the cloth, for example, as the number of layers of the cloth increases, the air permeability of the cloth is poorer, and thus the adsorption effect on the uppermost cloth is poorer; for another example, in the classification of cloth, leather is one of the cloth, but the leather itself has poor air permeability, and even the fixation of two layers of leather cannot be realized by adopting a negative pressure adsorption mode. There is a problem in that the fixing effect on the multi-layer cloth is poor.
