Then, setting an initial reference position of the preliminary wire 4: inserting a sufficient length of the prepared wire 4 from the inlet hole 19 of the movable wire pressing mechanism 15b into the inlet hole 19 of the fixed wire pressing mechanism 15a until the prepared wire 4 enters the tunnel 25, and at the same time, driving the cutter 22 to descend to the intersection of the long hole 26 and the tunnel 25 by the cutter lifting cylinder 24; next, the pressing head cylinder 20 of the movable wire pressing mechanism 15b drives the corresponding pressing head 18 to press the prepared wire 4, the fixed wire pressing mechanism 15a is fixed, the wire conveying cylinder 21 drives the movable wire pressing mechanism 15b to move towards the fixed wire pressing mechanism 15a, and the movable wire pressing mechanism 15b drives the prepared wire 4 to move synchronously until the front end of the prepared wire 4 abuts against one side of the cutting knife 22; finally, a pressing head cylinder 20 of the fixed wire pressing mechanism 15a drives a corresponding pressing head 18 to press the prepared wire 4, and a movable wire pressing mechanism 15b loosens the prepared wire 4, is driven by a wire conveying cylinder 21 and returns to the initial position; at this time, the setting of the initial reference position of the preliminary wire 4 is completed, and the preset length is set as the stroke of driving the movable wire pressing mechanism 15b each time by the wire conveying cylinder 21, and the stroke is called as a preset stroke; before feeding, the length of the preparation threads 4 is an initial length, the initial length of the preparation threads 4 is larger than the total number of thread holes 6 on the brush disc 8 multiplied by a preset length, and the initial length of the preparation threads 4 is 3600mm-5000 mm.

As shown in fig. 6 and 7, the shredding operation is then performed: firstly, a cutter 22 is driven to rise by a cutter lifting cylinder 24, meanwhile, a prepared wire 4 is tightly pressed by a movable wire pressing mechanism 15b, and then the prepared wire 4 is loosened by a fixed wire pressing mechanism 15 a; next, the wire conveying cylinder 21 drives the movable wire pressing mechanism 15b to move a preset stroke distance to the fixed wire pressing mechanism 15a, and the movable wire pressing mechanism 15b drives the prepared wire 4 to move synchronously, so that the distance from the front end of the prepared wire 4 to exceed the cutting knife 22 is the preset length; at this time, the fixed wire pressing mechanism 15a presses the preliminary wire 4, and the movable wire pressing mechanism 15b loosens the preliminary wire 4; the cutter 22 is driven by the cutter lifting cylinder 24 to descend and cut off the prepared material wire 4 to obtain a section of cut-off material wire 5 with a preset length, and meanwhile, the movable wire pressing mechanism 15b moves away from the fixed wire pressing mechanism 15a until the initial position is reached; after the shredding is completed, the cutter 22 is raised to the initial position; the leading end of the cut thread 5 has now left the tunnel 25 and the slot 45 and is suspended between the brush plate 8 and the thread cutting mechanism 10.

As shown in fig. 6-10, then the threading work is carried out: firstly, the guide piece cylinder 33 drives the guide piece 32 to the guide hole 34 to align with the material wire path, and then drives the guide piece 32 to approach the brush disc 8 until the guide hole 34 aligns with the working wire hole 6a, in the process, the guide hole 34 and the working wire hole 6a are at the same height, and the two guide arms 35 are closed; meanwhile, the movable wire pressing mechanism 15b is enabled to press the prepared wire 4, then the fixed pressing mechanism is enabled to release the prepared wire 4, the wire conveying cylinder 21 drives the movable wire pressing mechanism 15b to move towards the fixed wire pressing mechanism 15a for a preset stroke distance, the cut-off wire 5 is pushed towards the direction of the brush disc 8 by the prepared wire 4 and enters the working wire hole 6a after passing through the guide hole 34 to complete wire threading, and the front end and the rear end of the cut-off wire 5 are respectively abutted against the bearing baffle 44 and the supporting table 43; finally, the guide 32 is driven away from the brush plate 8 by the guide cylinder 33; then, the first opening-closing air cylinder 36 drives the two guide arms 35 to be separated, so that the guide holes 34 can leave the wire path, the guide piece 32 is driven to be away from the wire path, and the first opening-closing air cylinder 36 drives the two guide arms 35 to be closed; meanwhile, the wire feeding mechanism 1 performs one-time wire cutting operation.

After the new round of filament cutting work is finished and before the new round of filament threading work is carried out, the filament bending and lantern ring work needs to be finished on the cut-off material filaments 5 which are arranged in the working filament holes 6a at present.
