Description

Technical Field

[0001] This utility model relates to the field of textile technology, specifically to a high-efficiency yarn guide disc body. Background Technology

[0002] A guide roller, also known as a yarn guide roller, is a main drive roller that pulls the warp yarns out of a set of warp beams. The guide roller keeps the tension of the yarn bundle constant, unaffected by the back-and-forth movement of the guide, thus maintaining a constant winding speed, and can also change the direction of the yarn bundle.

[0003] A yarn guide plate typically consists of a plate body, bearings, a support frame, and an adjustment device. The plate body is the main component of the drafting guide plate, usually made of metal or plastic, and has appropriate channels or slots to allow yarn or cable to pass through smoothly. Existing plate bodies are disc-shaped with rounded sides. This shape results in low production efficiency and fabrics that are not soft enough. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency wire guide disc body to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A high-efficiency guide wire disc body includes a top surface, a bottom surface, and a side surface. The side surface is disposed between the top surface and the bottom surface. The side surface includes a first arc portion, a second arc portion, and a third arc portion. The first arc portion is connected to the top surface, the third arc portion is connected to the bottom surface, and the second arc portion is disposed between the first arc portion and the third arc portion. The first arc portion and the third arc portion have the same radius (R-angle), and the radius (R-angle) of the second arc portion is greater than the radius (R-angle) of either the first arc portion or the third arc portion.

[0007] In one possible implementation, a through hole is formed at the center of the top surface for mounting the disc onto the bearing.

[0008] In one possible implementation, a mounting groove is formed on the top surface.

[0009] In one possible implementation, the mounting groove is a recess with a right-angled triangular cross-section.

[0010] In one possible implementation, the roughness of the first arc portion and the third arc portion are the same, and the roughness of the first arc portion or the third arc portion is greater than the roughness of the second arc portion.

[0011] In one possible implementation, the radius (R) of the first or third arc portion is in the range of 1.5-2; the radius (R) of the second arc portion is in the range of 5.5-6.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] By changing the side of the guide disc from a single arc to three arc sections with different radius angles, the spinning efficiency of the guide disc and the softness of the woven fabric can be effectively improved. The mounting groove on the disc body can be connected to the reinforcing plate, etc., to improve the stability of the guide disc. Attached Figure Description

[0017] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0018] like Figure 1-3 As shown, a high-efficiency guide wire disc body includes a top surface 2, a bottom surface 5, and a side surface 1. The side surface 1 is located between the top surface 2 and the bottom surface 5. The side surface 1 includes a first arc portion 11, a second arc portion 12, and a third arc portion 13. The first arc portion 11 is connected to the top surface 2, the third arc portion 13 is connected to the bottom surface 5, and the second arc portion 12 is located between the first arc portion 11 and the third arc portion 13. The first arc portion 11 and the third arc portion 13 have the same radius (R-angle), and the R-angle of the second arc portion 12 is greater than the R-angle of either the first arc portion 11 or the third arc portion 13. Specifically, the R-angle of the first arc portion 11 or the third arc portion 13 ranges from 1.5 to 2, and the R-angle of the second arc portion 12 ranges from 5.5 to 6. The first arc portion 11 and the third arc portion 13 have the same surface roughness, and the surface roughness of the first arc portion 11 or the third arc portion 13 is greater than the surface roughness of the second arc portion 12. The surface roughness Ra of the first arc portion 11 and the third arc portion 13 ranges from 0.5 to 0.9, and the surface roughness Ra of the second arc portion 12 ranges from 0.4 to 0.8.

[0019] The side surface 1 of the guide disc is changed from a semi-circular arc to a D-shape with a small radius (R) near the top surface 2 and bottom surface 5, and a large radius (R) in the middle. The roughness of the part with the small radius (R) is greater than that of the part with the large radius (R). This allows the yarn to slide more easily from the center of the side surface 1 of the guide disc to the edge when weaving, effectively improving weaving efficiency and making the produced fabric softer.

[0020] Furthermore, a through hole 4 is formed at the center of the top surface 2, which is used to mount the disc onto the bearing. A mounting groove 3 is formed on the top surface 2. The mounting groove 3 is a recess with a right-angled triangular cross-section. The mounting groove 3 allows for additional fixation of the guide wire disc, such as by connecting a cylindrical reinforcing plate within the groove, reducing the centrifugal force on the guide wire disc during high-speed rotation, thereby improving the stability of the guide wire disc during high-speed rotation.
