[0031] The line feeding mechanism includes two servo motors 5 connected by bolt on one of mounting rib 4, two rotating shafts 6 rotatably connected between several mounting ribs 4, one end of two rotating shafts 6 is fixed to the output shaft of two servo motors 5 respectively, two groups of line feeding wheels 7 fixed to two rotating shafts 6 respectively, several guide cylinders 8 welded on several mounting ribs 4 respectively, several groups of tensioning wheels 9 rotatably connected on several mounting ribs 4 respectively, the number of each group of tensioning wheels 9 is three.

[0032] The line cutting mechanism includes arch frame 10 fixed to arch frame 3, several threading grooves are opened on arch frame 10, cutter holder 11 slidably connected to arch frame 3, two return springs 12 arranged between cutter holder 11 and arch frame 3, transmission assembly arranged on rack 1, electric sliding block 2 and arch frame 3.

[0033] The transmission assembly includes two sliding frames 13 slidably connected to rack 1, two sliding frames 13 are fixed to two electric sliding blocks 2 respectively, two groups of racks 14 fixed to two sliding frames 13 respectively, electric sliding block 2 drives rack 14 to move through sliding frame 13, cam frame 15 rotatably connected to one side of arch frame 3, one side of cam frame 15 contacts one side of cutter holder 11, two overrunning clutches 16 fixed to both sides of cam frame 15 respectively, two gears 17 fixed to the outer circle of two overrunning clutches 16 respectively, rack 14 drives cam frame 15 to rotate through gear 17 and overrunning clutch 16, in turn drives cutter holder 11 to move.

[0034] ​At the beginning, the worker places a bundle of paper tubes in the rack 1, so that the paper tubes are located between the arched frame 3 and the pushing frame 31. After the paper tubes are placed, the worker pulls one end of the lead from the wire reel of the wire laying device, and then passes it through the three tensioning wheels 9, the two wire feeding wheels 7 and the guide cylinder 8, and makes the end of the lead enter the threading slot of the arch frame 10. After the lead is threaded, the worker controls the electric sliding block 2 to move, which drives the pushing frame 31 and the sliding frame 13 to move. The pushing frame 31 moves and contacts one side of the paper tube, and drives the paper tube to move. When the row of paper tubes farthest from the pushing frame 31 moves to the lower side of the guide cylinder 8, the worker stops the electric sliding block 2, and starts the output shaft of the two servo motors 5 to rotate towards each other. The two servo motors 5 drive the two rotating shafts 6 to rotate towards each other, and the two rotating shafts 6 drive the two groups of wire feeding wheels 7 to rotate towards each other, so as to push the lower end of the lead into the paper tube. The tensioning wheel 9 can keep the lead tight. When the lead moves downward to the required length, the worker stops the servo motor 5, and controls the electric sliding block 2 to continue moving for a distance of one paper tube diameter. The sliding frame 13 continues to move and drives one of the racks 14 to engage with the gear 17, and drives the gear 17 to rotate. The gear 17 drives the cam frame 15 to rotate through the overrunning clutch 16. The cam frame 15 pushes the cutter frame 11 towards the opposite direction of the arch frame 10. The return spring 12 is compressed, and the cutter frame 11 cuts off all the leads. Through the above operation, multiple paper tubes can be inserted with leads at one time, and the insertion efficiency is improved. The cam frame 15 continues to rotate and no longer compresses the cutter frame 11. The return spring 12 rebounds and drives the cutter frame 11 to move reversely to reset. The rack 14 continues to move and disengages from the gear 17. The pushing frame 31 continues to move and pushes the next row of paper tubes to move to the lower side of the guide cylinder 8. Then the worker repeats the above operation until the leads are inserted into each row of paper tubes. After the leads are inserted into each paper tube, the worker controls the electric sliding block 2 to move reversely. The electric sliding block 2 reversely moves and drives the pushing frame 31 and the sliding frame 13 to move reversely. The sliding frame 13 reversely moves and drives the rack 14 to move reversely. The rack 14 reversely moves and engages with the gear 17 and reversely rotates the gear 17. Under the action of the overrunning clutch 16, the cam frame 15 does not rotate. After the sliding frame 13 resets to the initial position, the rack 14 disengages from the gear 17. Then the worker takes away the paper tubes with inserted leads, which is convenient for the next work.

[0035] In the embodiment 1, the two groups of wire feeding wheels 7 are rotatably connected to the rotating shaft 6. Figure 1 In the embodiment 1, the two groups of wire feeding wheels 7 are rotatably connected to the rotating shaft 6.
