Technical Field

[0001] The utility model relates to the technical field of textile machinery, in particular to a yarn feeding roller assembly. Background Art

[0002] A yarn feeding roller assembly is required when transporting the yarn.

[0003] When the yarn is transported by the yarn feed roller, the yarn transport tension is different. When the transported yarn is relatively loose, the transported yarn is not in sufficient contact with the yarn feed roller, which may easily cause unstable transport. When the transported yarn is relatively taut, it may easily cause the yarn to break. In order to solve the above problems, a yarn feed roller group is proposed in this application. Utility Model Content

[0004] The purpose of the present utility model is to solve the shortcomings existing in the prior art, and a yarn feeding roller group is proposed, which can automatically adjust the position of the tensioning roller according to the tensioning force of the yarn by setting an adjustment mechanism, thereby ensuring the stability and safety of the yarn transportation; and the device can dry and remove dust from the yarn, and is highly practical.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0008] Preferably, a limiting groove is provided on the yarn feeding roller, and the yarn is located in the limiting groove and is arranged against the inner wall thereof.

[0009] Preferably, the plurality of nozzles are all connected to the air outlet pipe, and the plurality of nozzles are distributed at equal intervals.

[0010] Preferably, each of the hollow rods is connected to a yarn feeding roller, and the yarn feeding roller is hollow.

DETAILED DESCRIPTION

[0020] 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 the embodiments.

[0021] Reference Figure 1-Figure 3 The yarn feeding roller 3 is provided with a U-shaped seat 1, and a yarn feeding roller 3 is provided above the U-shaped seat 1. A limiting groove 4 is provided on the yarn feeding roller 3. The yarn 15 is located in the limiting groove 4 and is set against its inner wall, so that the yarn 15 can be fed. The front and rear ends of the yarn feeding roller 3 are coaxially fixedly connected with a hollow rod 2. Each hollow rod 2 is connected to the yarn feeding roller 3. The yarn feeding roller 3 is hollow. Each hollow rod 2 passes through the U-shaped seat 1 and is rotatably connected to it. Each hollow rod 2 is fixedly connected to a rotary joint 7. The side wall of the U-shaped seat 1 is fixedly connected with an electric hot air blower 5, and the electric hot air blower 5 is fixedly connected to a connecting pipe 6. The connecting pipe 6 is coaxially fixedly connected to the rotary joint 7 on the front side, and the yarn feeding roller 3 is filled with hot air to increase its surface temperature, so as to dry the yarn 15 for feeding.

[0022] The rotary joint 7 on the rear side is coaxially fixedly connected to an air outlet pipe 8, which passes through the U-shaped seat 1 and is fixedly connected thereto. A plurality of nozzles 9 are fixedly connected to the bottom of the air outlet pipe 8, and the plurality of nozzles 9 are all connected to the air outlet pipe 8. The plurality of nozzles 9 are distributed at equal intervals, and the nozzles 9 are arranged above the yarn 15. The air is discharged through the nozzles 9 to blow away the dust attached to the outer wall of the yarn 15 being fed, thereby achieving dust removal.

[0023] A tensioning roller 14 is provided above the U-shaped seat 1, and two adjusting mechanisms are provided between the tensioning roller 14 and the U-shaped seat 1. The adjusting mechanism includes a limit block 12 coaxially rotatably connected to the tensioning roller 14. A sliding groove 10 is penetrated through the U-shaped seat 1, and the inner wall of the sliding groove 10 is fixedly connected to two sliding rods 11. The two sliding rods 11 both penetrate the limit block 12 and are slidably connected thereto. The side wall of the limit block 12 is fixedly connected with a spring 13, and the spring 13 is fixedly connected to the inner wall of the sliding groove 10. The outer walls of the yarn feeding roller 3 and the tensioning roller 14 are jointly wound with yarn 15. When the yarn 15 is relaxed, the tensioning roller 14 moves in the direction away from the yarn feeding roller 3. When the yarn 15 is tightened, the tensioning roller 14 moves in the direction close to the yarn feeding roller 3, thereby achieving appropriate tensioning force of the yarn 15.

[0024] In the present invention, during the yarn feeding process, the yarn 15 contacts the outer wall of the yarn feeding roller 3 and the outer wall of the tensioning roller 14. The transportation of the yarn 15 can drive the yarn feeding roller 3 and the tensioning roller 14 to rotate, thereby realizing the transportation of the yarn 15. The hot air generated by the electric hot air blower 5 is injected into the yarn feeding roller 3 through the connecting pipe 6 and the hollow rod 2 on the front side, so that the yarn feeding roller 3 is filled with hot air, thereby heating the outer wall of the yarn feeding roller 3 to dry the conveyed yarn 15, and the excess air in the yarn feeding roller 3 is ejected through the hollow rod 2 on the rear side, the air outlet pipe 8 and the multiple nozzles 9. , and ensures the high temperature of the yarn feeding roller 3, realizes the blowing of the conveyed yarn 15, blows off the dust attached to the outer wall of the yarn 15, and ensures the cleanliness of the surface of the yarn 15; when the yarn 15 is conveyed, the yarn 15 contacts the outer wall of the tensioning roller 14. When the tensioning force of the yarn 15 changes, the tensioning roller 14 moves and drives the limit block 12 to slide on the sliding rod 11. During this process, the spring 13 expands and contracts accordingly, and the tensioning roller 14 changes its position according to the tensioning force of the yarn 15, so that the yarn 15 is stretched and straightened, and the yarn 15 is conveyed well.

[0025] The utility model solves the problem of different yarn conveying tension in the prior art by providing an adjustment mechanism. When the conveyed yarn is relatively loose, the conveyed yarn is not in sufficient contact with the yarn feed roller, which easily leads to unstable conveying. When the conveyed yarn is relatively taut, the yarn is easily broken.
