Further, the cylindrical structure 71 has a step 72, and when the slide plate 31 slides to the left side of the step, the atmospheric hole 14 communicates with the communication position of the fourth chamber 32.

The working process is as follows: high-pressure gas is introduced into the right end of the first passage, low-pressure gas is introduced into the second passage 12, the low-pressure gas opens the check valve 9, the check valve enters the buffer tank 10, the cylinder 7 further enters the cylinder body 7 to push the piston rod 8, the piston rod 8 drives the eccentric wheel 5 to rotate for a certain angle through the matching of the chute 65 and the eccentric column 64, the eccentric wheel drives the first valve block 6 to rotate through the mounting seat 4, the first valve block 6 no longer blocks the first valve port of the first passage 2, the high-pressure gas further enters the fourth passage 15, and then enters the fifth chamber two 41 and the third chamber one outer cavity 29, so that the two parts become high pressure, the third diaphragm 39 is driven to bulge leftwards by the pressure difference between the fifth chamber two 41 and the fifth chamber one 40, the third diaphragm 39 sequentially drives the third valve seat 42, the third spring 44, the push rod 38, the sliding plate 31, the second valve rod 35 and the third valve rod 36 to move leftwards, the second valve rod 35 drives the second diaphragm 25, as mentioned above, when the valve plate 26 is raised to the left, the first third cavity inner cavity 28 and the first third cavity outer cavity 29 are conducted, the high-pressure gas at the first third cavity outer cavity 29 enters the first third cavity inner cavity 28, the high-pressure gas enters the second chamber second 19 through the fourth valve port 30, the second chamber second 19 becomes high-pressure, so that a pressure difference is generated between the second chamber second and the second chamber first 18, the first diaphragm 17 is forced to rise to the left, the first valve rod 23 is driven to move to the left, the first valve rod 23 no longer blocks the third valve port 23, the second passage 12 is conducted with the third passage 13, the low-pressure gas at the second passage 12 enters the sixth passage 49, in the process, the sliding plate 31 continues to move to the left, when the sliding plate moves to the left side of the step 72, a certain gap is generated between the sliding plate 31 and the cylindrical structure 71, so that the large air hole 14 is conducted with the first fourth cavity 32, the high pressure of the fourth chamber one 32 is slowly reduced under the influence of the atmospheric pressure, and simultaneously, the air pressure of the buffer tank 10 communicated with the fourth chamber one 32 is also slowly reduced until the pressures on the two sides of the piston rod 8 are balanced, the piston rod 8 is reset, the eccentric wheel 5 and the first valve block 6 are driven to reset, the first valve port of the first channel 2 is closed, then, all structures in the first shell 11 are reset, and the process is repeated in cycles, so that the effect of periodically conveying low-pressure air to the sixth channel 49 is achieved. On the other hand, the low-pressure gas entering the sixth channel 49 directly enters the jet channel 56 of the jet negative-pressure suction mechanism through the sixth chamber 50 and the seventh channel 51 (the second valve block 54 is at the right side at the beginning, the sixth chamber 50 is just communicated with the seventh channel 51, the second valve block 54 just blocks the eighth channel 52), the jet channel 56 forms negative pressure at the negative pressure channel 57, the negative pressure acts on the suction cavity 60 of the suction nozzle 59, the purpose of sucking the label 74 is achieved, meanwhile, the low-pressure gas of the third channel 13 also passes through the ninth channel 53, enters the sixth chamber 50 through the ninth channel 53 and acts on the right side of the second valve block 54, because the pressure-bearing area of the right side of the second valve block 54 is larger than that of the left side of the second valve block 54, the second valve block 54 gradually moves to the left, then blocks the seventh channel 51 and leads the eighth channel 52 to the sixth chamber 50, the low-pressure gas enters the blowing disc 62 through the eighth channel 52, finally, the label 74 is blown from the blowing port 63 of the blowing tray to be separated. It should be noted that, one end of the label 74 is pressed by a human hand at first, then the motor 48 drives the third housing 46 to turn over for a certain angle, the suction nozzle 59 presses the other end of the label 74 to suck the label 74, and then the third housing 46 turns over for a certain angle, so that the suction nozzle 59 can pull the other end of the label 74 upwards, the label 74 is as flat as possible and not easy to wrinkle, at this time, sewing is performed, and after the sewing is finished, the suction nozzle 59 does not suck the label 74 and the air blowing disc 62 blows air towards the label 74, so that the label 74 falls down naturally.
