On the basis of the embodiment 1 or the embodiment 2, the embodiment can realize the automation of the whole device, and the specific structure is that the respective thread suction ports (8 and 10) in the first thread suction mechanism and the second thread suction mechanism are internally provided with electromagnetic valves for controlling, and the automatic switch of the thread suction ports can be controlled through the electromagnetic valves; the electromagnetic valve is connected with the wire breaking device, and the wire breaking device is controlled to be opened and closed through the electromagnetic valve; a broken wire detection device 24 is arranged near the upper part of the second wire suction mechanism, and a photoelectric sensing element is arranged in the broken wire detection device 24; the electromagnetic valve and the photoelectric sensing element are controlled by PIC;
the flow of the tubular type drafting non-woven fabric automatic spinning-in device based on the structure is as follows:
a. when the wire is broken, the photoelectric sensing element of the wire breakage detection device 24 acts to transmit a signal to the PLC;
b, the PLC sends out an instruction, the electromagnetic valve in the filament sucking port 8 of the first filament sucking mechanism is closed, the filament breaking device cuts the filament, and then the electromagnetic valve of the filament sucking port 10 of the second filament sucking mechanism is opened to suck the filament;
c. after the set time, the electromagnetic valve of the thread suction port 10 of the second thread suction mechanism is closed, the thread cutting device cuts the thread, then the electromagnetic valve in the thread suction port 10 of the first thread suction mechanism is opened, the thread is sucked, and normal production can be realized;
d. the waste silk generated in the process is collected to the waste silk collecting device 22;
before the tows enter the filament sucking port 8 of the first filament sucking mechanism in the step c, the tows need to be gathered to the position above the filament sucking port 8 of the first filament sucking mechanism by means of the filament gathering device 23 on one side of the second filament sucking mechanism.
