However, such a structure is complicated, requires a plurality of steps, and is not ideal for solving the problem of the cloth having good air permeability. An automatic picking device for textile cloth disclosed in Chinese patent (application number: CN201910199163.X, application date: 2019, 3 and 15) comprises a cloth conveying unit and a picking unit, wherein a fixed seat is arranged at the top of an operation bottom surface, the picking unit is arranged at the front part of the cloth conveying unit, and the textile cloth is sucked and placed into the picking unit through the cloth conveying unit; the picking unit comprises a material receiving underframe fixed at the top of the operation bottom surface, and a pair of material receiving transverse moving frames which are oppositely arranged are arranged on the fixed seats at the two sides of the top of the material receiving underframe; a transverse supporting plate is fixed between the two material receiving transverse frames, a folding material receiving plate is arranged on the side part of the transverse supporting plate, and a plurality of material receiving suction rods are arranged at the bottom of the folding material receiving plate; the lower end part of the material receiving suction rod is communicated and connected with a material receiving sucker. This structure does not solve the problem of the limitation of suction by the suction cup.

The cloth picking device and the cloth picking unit of the sewing equipment disclosed in Chinese patent (application No. CN201610032620.2, application date: 2016, 1 and 19) comprise at least one pair of sharp object fixing plates, at least one pair of corresponding sharp object penetration adjusting devices and sharp object inclined moving devices, wherein at least one sharp object is obliquely fixed on each sharp object fixing plate, the sharp object penetration adjusting devices can adjust the angle of the sharp object penetrating into the cloth, the sharp object inclined moving devices ensure that the sharp objects penetrate into the cloth at a fixed inclination angle and a set depth, each pair of sharp object fixing plates are bilaterally symmetrical in the same vertical plane, the sharp objects on the sharp object inclined moving devices are bilaterally symmetrical, the sharp objects are driven to upwards shrink by the sharp object inclined moving devices, and the cloth can be put down under the effect of simultaneous upwards shrinking of the left and right sharp objects. This patent solves the problem of picking up of air-permeable cloth. However, each sharps fixing plate is driven by one moving device to enable the sharps to stretch and contract, and two moving devices are needed for one pair of sharps fixing plates, so that the cost is high. Moreover, only single-layer laid cloth can be picked up, for a stack of multi-layer cloth, the height of each picked up cloth is reduced a little, and the next layer of cloth cannot be accurately corresponded when the cloth is picked up again, so that the structure cannot be applied.
