DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] In order to clearly and completely describe the purpose and technical solution of the present utility model, and make the advantages more clear, the following further details the embodiments of the present utility model with reference to the drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present utility model, rather than all of the embodiments, and are only used to explain the embodiments of the present utility model, and are not used to limit the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1 - 4, the present utility model provides a technical solution: a drafting mechanism for blended yarns. The drafting mechanism for blended yarns includes: a base 1, on the top of which a support frame 3 is fixed; a rotating circular plate 5, on the end surface of which a roller shaft 10 is provided, and a winding roller 9 is connected to the surface of the roller shaft 10. The middle surface of the rotating circular plate 5 is connected to the output end of a motor 6. A groove is formed at the bottom of the winding roller 9; the groove is inserted on the output end of a hydraulic cylinder 7; and a slide rail 11 is arranged on the top surface of the base 1 and the bottom of the winding roller 9. On the surface of the support frame 3, a first conveying roller 2 and a second conveying roller 4 are provided. The heights of the first conveying roller 2 and the second conveying roller 4 are the same. On the other surface of the support frame 3, the motor 6 and the hydraulic cylinder 7 are inserted. When the winding roller 9 is full, the motor 6 is started, and the rotating circular plate 5 rotates, so that the upper and lower winding rollers 9 will change positions, and the full winding roller 9 is changed to the lower position.

[0023] A rotating ring 15 is connected to the middle of the surface of the rotating circular plate 5. A gear ring 13 is inserted on the surface of the rotating ring 15. The inner side of one side of the gear ring 13 is a tooth surface. On the surface of the rotating ring 15, a protruding column is provided. A gear 16 is inserted on the surface of the protruding column. The gear 16 is meshed and connected with the tooth surface of the gear ring 13. During this process, the rotating circular plate 5 will drive the rotating ring 15 to rotate together, and the rotating ring 15 will drive the gear 16 to rotate together. Since the gear 16 and the tooth surface of the gear ring 13 are meshed, the gear 16 will rotate, and the gear 16 will drive the limiting plate 17 to rotate. The limiting plate 17 drives the limiting column 14 to move. Since one end of the limiting column 14 is inserted into the inside of the limiting block 18, and the limiting block 18 is fixed on the gear ring 13, the limiting column 14 will make a linear reciprocating movement, and the limiting column 14 drives the blade 12 to cut the yarn.

[0024] A limiting plate 17 is provided on the surface of the gear 16. One end of the limiting plate 17 is inserted into the protruding main body on the surface of the rotating ring 15. The other end of the limiting plate 17 is connected to a limiting column 14. A blade 12 is provided on the surface of the limiting column 14. A support bar 8 is provided on the surface of the gear ring 13. The other end of the support bar 8 is fixed on the support frame 3. A limiting block 18 is provided on the surface of the gear ring 13. A limiting hole is formed on the surface of the limiting block 18, and the limiting column 14 is connected to the inside of the limiting hole. When the full winding roller 9 is changed to the lower position, the yarn has been cut by the blade 12. The groove of the roller shaft 10 will be clamped on the output end of the hydraulic cylinder 7. The hydraulic cylinder 7 is started to pull out the roller shaft 10, and the full winding roller 9 falls on the slide rail 11 and slides to a position where it is easy to collect.

[0025] During actual use, when the winding roller 9 is full, the motor 6 starts, the rotating circular plate 5 rotates, causing the upper and lower winding rollers 9 to change positions. The full winding roller 9 is switched to the lower position. During this process, the rotating circular plate 5 drives the rotating ring 15 to rotate together, and the rotating ring 15 drives the gear 16 to rotate together. Since the gear 16 meshes with the surface of the gear ring 13, the gear 16 rotates. The gear 16 drives the limiting plate 17 to rotate, and the limiting plate 17 drives the limiting column 14 to move. Since one end of the limiting column 14 is inserted into the inside of the limiting block 18, and the limiting block 18 is fixed on the gear ring 13, the limiting column 14 will make a linear reciprocating movement. The limiting column 14 drives the blade 12 to cut the yarn. When the full winding roller 9 is switched to the lower position, the yarn has been cut by the blade 12. The groove of the roller shaft 10 will be clamped to the output end of the hydraulic cylinder 7. The hydraulic cylinder 7 starts to pull out the roller shaft 10, and the full winding roller 9 falls on the slide rail 11 and slides to a position where it is easy to collect.

[0026] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
