At zero degrees, the air paths of the suction nozzle 40 and the first blowing nozzle 50 are smooth, the suction nozzle 40 sucks the signature 300, the first blowing nozzle 50 blows air to the pile of the signatures 300 to 70 degrees, the air path of the paper sucking air hole 311 on the paper conveying belt 31 is smooth, the signatures 300 are adsorbed on the paper conveying belt 31, 70 degrees to 90 degrees, the first blowing nozzle 50 stretches into the space between the lowest signature 300 and the rest of the signatures 300 to blow air, 100 degrees, the first blowing nozzle 50 stretches out of the air path to close, 120 degrees, the suction nozzle 40 closes, 130 degrees, the second blowing nozzle 60 blows air upwards to assist in feeding the signatures, 180 degrees, the paper conveying belt 31 starts to deliver the signatures 300 to the paper conveying roller 33, the paper sucking air hole 311 on the paper conveying belt 31 closes, the air path of the paper sucking air hole 312 is smooth, 200 degrees, the second blowing nozzle 60 closes, 240 degrees, the air path of the first blowing nozzle 50 is smooth, the air path of the next feeding the signatures 300 starts to blow air until the next feeding signature, 260 degrees, the paper blowing hole 312 on the paper conveying belt 31 closes, the next feeding is completed, the next feeding is ready to convey the signatures to 360 degrees.
The application has the following technical effects: the collating and feeding of the books are carried out by adopting a belt, the paging and feeding of the books are completely controlled by adopting a gas circuit, the abrasion is small, and the collating and feeding machine is very suitable for the thin-distribution of the books; the speed is high, and the structure is simple; the direction of transfer of signature 300 is consistent with the direction of toggle lever 200, reducing the damage to the signature tail from toggle lever 200.
The foregoing description is only of the preferred embodiments of the present application and is not intended to limit the scope of the application, and all equivalent structural changes made by the description of the present application and the accompanying drawings or direct/indirect application in other related technical fields are included in the scope of the application.
