[0029] A specific application of this embodiment is that the present invention includes four steps during use, namely, a needle material orientation part, a needle material screening part, a needle material transmission part and a secondary needle arrangement part, as shown in the action flow chart of Question 10, which is as follows;

[0030] Needle material orientation part: Pour an appropriate amount of needle material from the positioning frame 3 into the vibration guide groove 2 from top to bottom. The vibration motor drives the vibration guide groove 2 to vibrate back and forth. The raw material needles are initially oriented after passing through the vibration guide groove 2, and then fall into the horizontal needle frame 1201 part of the screen needle frame 12. Most of the needles will be vertically mounted on the screen needle frame 12, and a small number of needles will deviate from the position. Fig. 9As shown, the structure of the needle raw material generally includes a large-sized needle tail and a needle tip. The groove width of the screen needle frame 12 is larger than the needle tip diameter and slightly smaller than the needle tail diameter. Even if the raw material needle falls horizontally into the needle groove 1203, it will be flipped to a vertical direction because the force point is close to the needle tail and gravity.

[0031] Needle material screening part: Motor 10 drives the gear in the gear protection frame 4 to rotate, and the push plate 5 is extended through the rack on the top of the push plate 5 that cooperates with the gear. Then the motor 2 6 drives the ball screw 7 to rotate, and the push plate 5 makes a linear motion to push the needle material from the horizontal needle rack 1201 part of the screening needle rack 12 into the inclined needle rack 1202 part. Then the motor 10 reverses to retract the push plate 5 first, and then resets it. The needles on the inclined needle rack 1202 slide to the needle outlet 13 by gravity, which is used to place the needles of a small number of the arranged needle materials that are deviated from the position and fall from the gap between the needle grooves 1203, so as to realize the screening and separation of the needle materials.

[0032] Needle material conveying part: a small number of needles that have deviated from their positions fall from the gaps between the needle grooves to the ramp plate 18. Under the action of the guide plate 17, the needle material slides into the guide pipe 8 at the bottom, and finally slides into the belt protection frame 1 under the action of gravity, ready for secondary needle arrangement.

[0033] Secondary needle arrangement part: the pulley 14 rotates, and the needle sweeping plate 16 rotates attached to the belt 15. The rotation of the needle sweeping plate 16 will sweep the needle raw materials transported in by the guide pipe 8 onto the vertical baffle. When it rises to a certain height, the needle sweeping plate 16 has an inclination, so the needle raw materials will slide down to the positioning frame 3 for secondary needle arrangement.

[0034] The above embodiments are only used to illustrate the technical solutions of the present invention. The protection scope of the present invention is not limited to the description scope of the above embodiments. Any modifications and changes made to the present invention by those skilled in the art without creativity shall fall within the protection scope of the present invention.
