Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-2, the present invention provides a technical solution: a yarn feeding roller comprises a support 10 and a yarn feeding roller 20, wherein one end of the yarn feeding roller 20 is provided with a mounting hole 21. The inner wall of the mounting hole 21 is provided with a key groove 211, and the key groove 211 extends along the axial direction. One end of the yarn feeding roller 20 provided with the mounting hole 21 is sleeved with a driven gear 30; the other end of the yarn feeding roller 20 far away from the mounting hole 21 is connected with a mounting shaft 22. The outer peripheral surface of the mounting shaft 22 is provided with a connection key 221. Two first and

second fixing plates

40 and 50 are oppositely disposed to the support 10. The first fixing plate 40 is provided with a positioning shaft 41 for connecting with the mounting hole 21. The second fixing plate 50 is provided with a positioning hole 51 for mounting the mounting shaft 22; the plurality of yarn feeding rollers 20 are connected through the matching of the mounting holes 21 and the mounting shafts 22 and are arranged between the first fixing plate 40 and the second fixing plate 50 which are oppositely arranged; the yarn feeding roller 20 close to the second fixing plate 50 is connected with a transmission gear 60 positioned at the other side of the second fixing plate 50; the transmission gear 60 is connected with a driving motor 70; the driving motor 70 is provided on the stand 10.
