The first air suction device 3 comprises a first air suction plate 31, two first pipes 32, two second pipes 33, two three-way pipes 34 and two first air pumps 35, the first air suction plate 31 is installed at the lower end of the bottom frame 1, an air suction cavity is formed in the first air suction plate 31, the left end and the right end of the air suction cavity are communicated with the two first pipes 32, a three-way pipe 34 is connected between the first pipe 32 and the second pipe 33, the three-way pipe 34 is installed on the bottom frame 1, a first air pump 35 is installed on the three-way pipe 34, the first air pump 35 is communicated with the three-way pipe 34, during specific work, external air is sucked into the air suction cavity and the air cavity 293 through the first air pump 35, and accordingly air suction is performed on base cloth and middle-layer cloth.

Rubber pad 294 on evenly set up the gas pocket, the gas pocket is linked together with air cavity 293, seted up corresponding hole on the L type frame 27, and correspond hole and air cavity 293 on the initial position displacement board 291 and be corresponding the intercommunications relation, guaranteed that the gas in air cavity 293 can enter into No. two pipes 33 smoothly, when displacement board 291 moves to the outside, at this moment, gas pocket and air cavity 293 are no longer aimed at, air cavity 293 loses the lower terminal surface that suction no longer was held to middle floor's cloth, the degree of difficulty that displacement board 291 moved to the outside has been reduced greatly, the upper end of No. two pipes 33 with correspond the jogged joint.

The second air suction device 5 comprises a fixed air cylinder 51, a connecting frame 52, a second air suction plate 53, a second air pump 54 and a positioning piece 55, the fixed air cylinder 51 is installed on the inner side wall of the movable frame 4, the ejection end of the fixed air cylinder 51 is installed on the connecting frame 52, the connecting frames 52 are connected with the second air suction plate 53 through a pin shaft, a main cavity is formed in the second air suction plate 53 and communicated with the second air pump 54, the second air pump 54 is installed on the second air suction plate 53, the positioning piece 55 is embedded in the connecting frame 52, the lower end face of the positioning piece 55 is tightly attached to the upper end face of the second air suction plate 53, the surface layer cloth is flatly placed on the second air suction plate 53 to be air-sucked and positioned, then the positioning piece 55 is drawn out, the second air suction plate 53 is turned over to arrange the surface layer cloth downwards, the positioning piece 55 is inserted again, so as to position the angle of the second air suction plate 53, and during specific work, the second air pump 54 sucks the outside air into the main chamber, thereby performing air suction positioning on the surface cloth.

The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are given by way of illustration of the principles of the present invention, and that various changes and modifications may be made without departing from the spirit and scope of the invention as defined by the appended claims. The scope of the invention is defined by the appended claims and equivalents thereof.
