Description

Technical Field

[0001] The utility model belongs to the field of non-alkali glass fiber yarn spinning, and particularly relates to a tensioning device for non-alkali glass fiber yarn spinning. Background Art

[0002] At present, the tensioning device for non-alkali glass fiber yarn spinning usually adjusts the tension by adjusting the height of the tensioning roller. To a certain extent, this method can meet the basic tensioning requirements, but many disadvantages have also emerged in practical applications.

[0003] First of all, when tensioning and adjusting different-width non-alkali glass fiber yarns during transportation, due to the lack of suitable limiting components, the position of the yarn is likely to shift. This will not only affect the tensioning effect of the yarn, but may also cause quality problems in the subsequent processing of the yarn. For example, the offset yarn may break away from the tensioning roller and rub against other parts of the equipment, resulting in damage or breakage of the yarn surface, thus interrupting the conveying work. And different-width yarns require different degrees of tension, but due to the interference of position offset, it is very difficult to accurately adjust to the appropriate tension.

[0004] In view of this, we have proposed a tensioning device for non-alkali glass fiber yarn spinning. Summary of the Utility Model

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1 to 4 , the present utility model provides a technical solution: a tensioning device for non-alkali fiberglass yarn spinning, including: a support base 1, a concave plate 6 and a tensioning roller 7. The tensioning roller 7 is arranged above the inside of the concave plate 6. A limit ring 8 is respectively arranged on the front and rear sides of the tensioning roller 7. A plurality of groups of universal balls 16 are respectively installed on the inner walls of the two limit rings 8;

[0026] A driving ring 12 is respectively connected to the lower sides of the two limit rings 8 through a connecting rod 15. A rotating screw 10 is installed inside the driving ring 12. A separating ring 11 is installed in the middle of the rotating screw 10. A servo motor 9 is installed on the right side of the concave plate 6. The output shaft of the servo motor 9 is connected to the rotating screw 10;

[0027] The thread directions on the front and rear sides of the rotating screw 10 are opposite with the separating ring 11 as the center. The inner walls of the driving rings 12 are respectively provided with internal threads matching the rotating screw 10. The driving rings 12 and the rotating screw 10 are rotationally connected through threads.

[0028] The front side of the rotating screw 10 is a left-handed thread, and the rear side is a right-handed thread.

[0029] The multiple groups of universal balls 16 are installed at equal intervals in a ring shape. The ball parts of the multiple groups of universal balls 16 all face the tensioning roller 7 and are in contact with it.

[0030] A bearing is installed at the rear end of the rotating screw 10. The bearing is installed on the inner side above the concave plate 6, and the rear end of the rotating screw 10 is connected to the inner side of the bearing.

[0031] A central box 5 is provided below the concave plate 6. A cavity 13 is provided inside the central box 5. The lower end of the concave plate 6 extends into the cavity 13. An electric push rod 14 is installed in the cavity 13, and the upper end of the electric push rod 14 contacts the concave plate 6.

[0032] The support base 1 is installed below the central box 5.

[0033] A roller plate 2 is installed on each of the left and right sides above the support base 1. A first rotating roller 4 is installed above the front roller plate 2, and a second rotating roller 3 is installed above the rear roller plate 2.

[0034] Please refer to Figures 1 to 3 , as the first embodiment of the present utility model: In actual use, the non-alkali fiberglass yarn spinning is passed around the first rotating roller 4, the tensioning roller 7 and the second rotating roller 3 for the transportation of the non-alkali fiberglass yarn spinning. When passing around the tensioning roller 7, it can pass above or below the tensioning roller 7 according to actual needs. When it is necessary to adjust the tension during the transportation of the non-alkali fiberglass yarn spinning, the electric push rod 14 drives the concave plate 6 to move up and down in the cavity 13, so as to drive the tensioning roller 7 to move up and down to adjust the use height. When the non-alkali fiberglass yarn spinning is located below the tensioning roller 7, by pressing down the tensioning roller 7, the tension can be increased. When it is in the upper position, by raising the tensioning roller 7 to lift the non-alkali fiberglass yarn spinning, the tension can be increased, so as to facilitate the flexible adjustment of the tension during the transportation process.

[0035] Please refer to Figure 1 , Figure 2 and Figure 4 , as the second embodiment of the present utility model: Before the transportation of the non-alkali fiberglass yarn spinning, the servo motor 9 can be driven to drive the rotating screw 10 to rotate. The rotating screw 10 rotates in the two driving rings 12, so as to drive the two driving rings 12 to move. The two driving rings 12 can respectively drive the two limiting rings 8 to move through the connecting rods 15. When the limiting rings 8 move, they can drive the universal balls 16 to slide along the outer side of the tensioning roller 7, and when the tensioning roller 7 rotates, it can also drive the ball parts of the universal balls 16 to rotate, so that the limiting rings 8 are not easy to affect the rotation of the tensioning roller 7;

[0036] When the servo motor 9 rotates forward, the two limiting rings 8 approach each other. When the servo motor 9 rotates in reverse, the two limiting rings 8 move away from each other. Furthermore, the distance between the two limiting rings 8 can be adjusted according to the non-alkali fiberglass yarn spinning with different widths, so as to limit the non-alkali fiberglass yarn spinning during transportation and prevent its position from shifting and causing damage. And because the limiting rings 8 make the position of the non-alkali fiberglass yarn spinning during transportation not easy to shift, it is convenient to accurately adjust to the appropriate tension.

[0037] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
