[0009] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Example

[0010] like Figure 1As shown, a needle exchange sheath feeding mechanism includes a vibration plate 1, and the vibration plate 1 can adopt the vibration plate structure of the safety syringe needle seat feeding device disclosed in the publication (announcement) number: CN217894276U, and can also adopt the vibration plate for directional sorting and conveying of injection needle seats disclosed in the publication (announcement) number: CN112093428A, and can also adopt the vibration plate structure of the automatic directional feeding machine of the blood collection needle hard seat disclosed in the publication (announcement) number: CN105109931A. As long as the structure of the material channel is matched with the shape of the sheath, the vibration plate 1 adjusts the sheath to feed in the same state with the open end facing upward, and the vibration plate 1 The discharge end of the vibrating plate 1 is provided with an inclined receiving plate 6, and a group of receiving grooves are provided on the receiving plate 6. The sleeve directly falls into the receiving groove along the inclined discharge end. The receiving plate 6 is arranged on the slider 3, and the slider 3 is slidably arranged on the first guide rail 4.
