The feeding device also includes a limiting assembly 40, and the limiting assembly 40 includes: a first positioning plate 41 and a second positioning plate 42, which are relatively arranged on the first side and the second side of the bearing surface 21, and a limiting space is formed between the first positioning plate 41 and the second positioning plate 42.

[0040] The material channel assembly in this embodiment is also provided with a third screening section 203, and the third screening section 203 is connected to the first turning section 204. A limiting assembly is provided in the third screening section 203 to form a limiting space, which only allows the upright soft needle seat 10 to pass through, while the lying soft needle seat 10 and the inclined soft needle seat 10 are blocked outside the limiting assembly and fall into the material bin. The first limiting plate and the second limiting plate are arranged perpendicular to the bearing surface.

[0041] The material channel assembly also includes a second material turning section 205, on which a turning bar 26 is provided. The turning bar 26 is arranged on the second side of the bearing surface 21 and gradually extends toward the top of the guide surface 22 along the conveying direction, so that the soft needle seat 10 moves along the turning bar 26 and rotates from the first side of the bearing surface 21 to the second side.

[0042] The second turning section 205 in this embodiment is connected to the third screening section 203 to turn over the soft needle seat 10 that has fallen down or has not been erected after passing through the third screening section 203 to an upright position. Specifically, a turning bar that gradually extends inward and upward is arranged on the outer side of the bearing surface of the second turning section 205, so that the soft needle seat 10 gradually stands up inward along one end of the outer side of the bearing surface under the guidance of the turning bar, and finally leans against the guide surface, so that the support body 12 of the soft needle seat 10 rotates from the bearing surface 21 to the guide surface 22.
