A discharging push rod 7 is arranged in the discharging hopper 4 at a position opposite to the adjusting door, and one end of the discharging push rod 7 far away from the adjusting door is connected with a discharging cylinder 8; therefore, the blanking cylinder 8 can drive the blanking push rod 7 to move towards the adjusting door, so that the outer wire is pushed out from the elastic adjusting door 6. After adopting above-mentioned structure, the unloading process is: the external thread enters the blanking hopper 4 through the blanking barrel 2 and slides to the position of the adjusting door along the inclined anti-nesting bottom 9 at the bottom of the blanking hopper 4; the blanking push rod 7 is driven by the blanking cylinder 8 to push the outer wire to move towards the direction of the adjusting door; the outer wire further extrudes the elastic adjusting door 6, the elastic adjusting door 6 generates elastic deformation, and the outer wire falls to the starting end of the sequencing unit; the feeding push rod 7 retracts, and the outer wires which do not fall off are pressed back into the feeding hopper 4 under the elastic action of the elastic adjusting door 6.

Referring to fig. 1, 2 and 3, the sorting unit of the automatic external thread feeder includes a striker plate 10, a sorting rail 11, a linear vibration feeder 12 and a carding mechanism 13.

And the outer wire with the required posture is continuously conveyed on the sequencing track 11 through the carding holes. And because the sorting track 11 is V-shaped or U-shaped, the posture of the outer silk is not changed any more in the transportation process, thereby realizing automatic sorting and posture adjustment.

Referring to fig. 8 and 9, the feeding unit of the automatic external thread feeding machine comprises a pushing mechanism and a pushing cylinder 18. The material pushing mechanism is arranged at the tail end of the sequencing track 11 and comprises a material pushing block 19 and a material pushing support 20; the pusher blocks 19 are arranged on both sides of the sequencing rail 11 opposite to the feed end of the tapping machine scraper-trough conveyor 1.

Referring to fig. 1, 2, 4, 5, 6, 7 and 10, the control circuit unit of the automatic external thread feeder comprises a control chip PLC, a correlation photoelectric switch 17, an in-position sensor and a full-material sensor. The signal input end of the control chip PLC is connected with the correlation photoelectric switch 17, the in-place sensor and the full-material sensor, and the signal output end of the control chip PLC is connected with the blanking cylinder 8, the material combing cylinder 14, the material pushing cylinder 18 and the material combing cylinder 14. The emitter of the correlation photoelectric switch 17 is arranged on one side of the starting end of the sequencing track 11, and the receiver is arranged on the other side of the sequencing track 11 in a matching way. The correlation photoelectric switch 17 will detect whether there is an external thread at the start of the sequencing unit. If the photoelectric switch 17 does not detect the external thread, the control chip PLC drives the discharging cylinder 8, and the discharging push rod 7 is driven by the discharging cylinder 8 to push the external thread in the discharging hopper 4, so that the external thread falls to the starting end of the sequencing track 11 from the discharging hopper 4. An in-position sensor is mounted at the end of the sequencing track 11 and functions to determine whether the outer wire reaches the reach of the pusher mechanism. The full material sensor is arranged on the tapping machine slide 1 and is used for determining whether an external thread exists on the tapping machine slide 1. The blanking cylinder 8 is responsible for controlling whether the plastic push rod 14 carries out pushing operation or not. The material combing cylinder 14 is responsible for controlling whether the material combing mechanism 13 carries out material combing operation or not. The pushing cylinder 18 is responsible for controlling whether the pushing block 19 pushes the outer wire from the end of the sequencing unit onto the tapping machine scraper-trough conveyer 1. The control circuit unit works as follows: when the opposite photoelectric switch 17 cannot detect that the starting end of the sequencing unit has the external thread, the control chip PLC controls the blanking cylinder 8 to work, and the blanking cylinder 8 drives the blanking push rod 7 to perform blanking operation; when the in-place sensor detects the outer wire and the full-material sensor does not detect the outer wire, the control chip PLC controls the material pushing cylinder 18 to drive the material pushing mechanism to perform material pushing operation; the control chip PLC controls the material combing cylinder 14 to periodically push the material combing cylinder to comb the material.

This automatic change outer silk material loading machine's use does: (1) the outer wire enters the blanking hopper 4 through the blanking barrel 2 and slides in the blanking hopper 4 along the anti-nesting bottom 9 to the regulating gate.

Then, the feeding push rod 7 is retracted, and the outer wire which does not fall down is pressed back into the lower hopper 4 under the elastic action of the elastic adjusting door 6.

(2) The outer wire drops to the initiating terminal of sequencing track 11 from the discharge end of hopper 4 down, through blockking of striker plate 10. The outer wires are carried along the sorting rail 11 under the vibration of the linear vibration feeder 12. Because the sorting track 11 is a V-shaped strip track, the posture of the outer wire can be continuously adjusted in the transportation process to meet the requirement, and after encountering the material combing mechanism 13, the outer wire which does not meet the form requirement can not enter the material combing hole formed by the combination of the rear material combing rubber plate 15 and the front material combing rubber plate 16, and is pushed back to the starting end of the sorting track 11 by the material combing mechanism 13 driven by the material combing cylinder 14. And the outer wire with the required posture continues to move on the sequencing track 11 through the carding hole. And since the sorting track 11 is V-shaped, the attitude of the outer wire will not change during transport.

(3) When the in-place sensor detects the outer wire and the full-material sensor cannot detect the outer wire, the control chip PLC controls the material pushing cylinder 18 to drive the material pushing block 19 to vertically push the outer wire to the inlet of the tapping machine scraper-trough conveyer 1 through the material pushing support 20, and the outer wire enters the tapping machine scraper-trough conveyer 1.
