[0037] The needle suction component 6 is a strong magnet, and a plurality of needle suction components 6 are arranged on the same track 5 and sequentially arranged in the rotation direction of the track 5 to form a needle suction ring. One needle suction ring can be arranged on the track 5, and the width of the needle suction ring is not less than four fifths of the width of the track 5. Of course, when the size of the needle suction component 6 is small, the needle suction component 6 can be uniformly arranged on the surface of the track 5 to form a matrix structure. Two (or three, or more) needle suction rings can be arranged on the track 5.

[0038] A needle head collecting plate 7 is arranged above the track frame 1 and fixed relative to the track frame 1, which is used to collect the needle heads sucked by the needle suction component 6.

When a plurality of needle suction rings are arranged on the track 5, the spacing between the needle suction rings is not greater than 2mm. The lower end edge of the needle head collecting plate 7 is lower than the outer side of the needle suction component 6. When the needle heads falling on the ground are sucked by the needle suction ring and move on the track 5, they will be stopped by the needle head collecting plate 7 when they move to the needle head collecting plate 7. The needle suction ring (needle suction component 6) is used to pick up the needle heads, and the needle head collecting plate 7 is used to collect the needle heads.

[0039] The track group further comprises a motor for outputting torque, which is a servo motor that can rotate in both forward and reverse directions.
