Description

Technical Field

[0001] This utility model relates to the field of textile machinery technology, specifically to a yarn spinning tensioner. Background Technology

[0002] Maintaining proper yarn tension during yarn spinning is crucial for ensuring uniform fabric tension and improving production efficiency. Traditional yarn tensioning devices suffer from problems such as inconvenient adjustment and poor stability, leading to uneven yarn tension and affecting textile quality. Therefore, developing a yarn spinning tensioner has broad application prospects.

[0003] Referring to the yarn tensioner in the warp knitting machine with announcement number CN205133928U, it includes a rod-shaped connecting rod with a disc-shaped pressure plate sleeved on the connecting rod. There are two pressure plates: pressure plate one and pressure plate two. Both pressure plate one and pressure plate two are equipped with springs. Under the elastic force of the springs, pressure plate one tends to fit against pressure plate two. A material passage for yarn to pass through is formed between pressure plate one and pressure plate two. The yarn tensioner in this warp knitting machine has a compact structure. As can be seen from the above, although this tensioner can be used well to tension textile yarns, it is usually not convenient to roll and flatten the yarn, making the yarn prone to bending, which affects the yarn tensioning effect and often troubles users. Utility Model Content

[0004] The purpose of this invention is to provide a yarn tensioner to solve the problem mentioned in the background art that although the tensioner can be used well to tension textile yarns, it is usually not convenient to roll and flatten the yarn, making the yarn prone to bending and thus affecting the yarn tensioning effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a yarn textile tensioner, comprising a base plate, a vertical plate at the top of the base plate, a tensioning seat on one side of the surface of the vertical plate, a base plate on the surface of the vertical plate on one side of the tensioning seat, side connecting frames on both sides of the top of the base plate, a lower pressure roller rotatably mounted on the lower inner wall between the side connecting frames, an upper pressure roller above the lower pressure roller, a nut seat at the top of each side connecting frame, a threaded pin threaded into the internal thread of the nut seat, and the top of the threaded pin extending... The bottom end of the threaded pin extends to the outside of the nut seat and is rotatably connected to one end of the upper pressure roller. A bearing is provided on the vertical plate surface of the base plate away from the tension seat. A disc is installed on the end of the bearing away from the vertical plate. A winding roller is provided at the center of the disc surface. A limiting disc is provided on the inner wall of the disc outside the bearing. A linkage arm is rotatably installed on the vertical plate surface on one side of the limiting disc. A limiting roller is installed on the outer wall of the linkage arm through a bracket. The outer wall of the limiting roller contacts the outer wall of the limiting disc.

[0006] Preferably, a first limiting cavity is provided on one side of the tensioning seat, and a first limiting seat is slidably connected inside the first limiting cavity. A first tensioning roller is installed on the surface of the first limiting seat. The tension of the yarn is adjusted by setting the first tensioning roller.

[0007] Preferably, a second limiting cavity is provided inside the tensioning seat on one side of the first limiting cavity, and a second limiting seat is slidably connected inside the second limiting cavity. A second tensioning roller is installed on the surface of the second limiting seat. The tension of the yarn is adjusted by setting the second tensioning roller.

[0008] Preferably, a first threaded rod is threadedly installed at the top of the tensioning seat at the first limiting cavity position. The bottom end of the first threaded rod is rotatably connected to the top end of the first limiting seat. A first handle is installed at the top end of the first threaded rod. By rotating the first handle, the first threaded rod is driven to rotate and slide up and down at the top of the tensioning seat.

[0009] Preferably, a second threaded rod is threadedly installed at the top of the tensioning seat at the second limiting cavity position. The bottom end of the second threaded rod is rotatably connected to the top end of the second limiting seat. A second handle is installed at the top end of the second threaded rod. By rotating the second handle, the second threaded rod is driven to rotate and slide up and down at the top of the tensioning seat.

[0010] Preferably, a spring telescopic component is rotatably mounted on the surface of the upright plate on one side of the linkage arm via a bracket. The end of the spring telescopic component away from the upright plate is connected to the inner wall of the linkage arm. The spring telescopic component is provided to apply elastic pressure to the linkage arm.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the yarn textile tensioner not only reduces the phenomenon of yarn bending, but also reduces the phenomenon of yarn loosening and falling off the outer wall of the winding roller, so as to ensure the tensioning effect of the tensioner on the yarn when it is used, and achieves the purpose of easy adjustment of yarn tension.

[0012] (1) By turning the threaded pin, the threaded pin rotates and slides inside the nut seat, so that the threaded pin drives the upper pressure roller to rise and fall, thereby adjusting the distance between the upper pressure roller and the lower pressure roller. When the yarn on the outer wall of the winding roller is passed between the upper pressure roller and the lower pressure roller and then passed under the second tension roller or the first tension roller, and the yarn is transmitted and wound, the upper pressure roller and the lower pressure roller can roll and flatten the yarn to reduce the phenomenon of yarn bending, thereby ensuring the tensioning effect of the tensioner on the yarn when it is used.

[0013] (2) The spring extension component applies elastic pressure to the linkage arm, so that the linkage arm drives the limiting roller to elastically abut against the outer wall of the limiting plate. When the yarn on the outer wall of the winding roller is unwound, the limiting roller abuts against the outer wall of the limiting plate to limit the phenomenon of the winding roller rotating due to inertia. This can reduce the phenomenon of the yarn on the outer wall of the winding roller becoming loose and falling off, thereby improving the unwinding tension effect of the yarn.

[0014] (3) By rotating the first handle and the second handle, the first threaded rod and the second threaded rod are respectively driven to rotate and slide on the top of the tensioning seat, so that the first limiting seat and the second limiting seat are respectively driven to slide inside the first limiting cavity and the second limiting cavity. The height of the first tensioning roller and the second tensioning roller can be adjusted as needed according to the tightness of the yarn, thereby achieving the purpose of easily adjusting the yarn tension.

[0027] A second threaded rod 12 is threadedly installed at the top of the tensioning seat 3 at the second limiting cavity 9 position. The bottom end of the second threaded rod 12 is rotatably connected to the top end of the second limiting seat 10. A second handle 13 is installed at the top end of the second threaded rod 12.

[0028] In use, by rotating the second handle 13, the second threaded rod 12 is driven to rotate and slide up and down on the top of the tensioning seat 3;

[0029] A base plate 14 is provided on the surface of the vertical plate 2 on one side of the tensioning seat 3. Side connecting frames 22 are provided on both sides of the top of the base plate 14. A lower pressure roller 23 is rotatably mounted on the lower inner wall between the side connecting frames 22. An upper pressure roller 24 is provided above the lower pressure roller 23. A nut seat 25 is provided on the top of each side connecting frame 22. A threaded pin 26 is threaded into the internal thread of the nut seat 25. The top end of the threaded pin 26 extends to the outside of the nut seat 25, and the bottom end of the threaded pin 26 extends to the outside of the nut seat 25 and is rotatably connected to one end of the upper pressure roller 24. A bearing 21 is provided on the surface of the vertical plate 2 on the side of plate 14 away from the tension seat 3. A disc 15 is installed on the end of the bearing 21 away from the vertical plate 2. A winding roller 16 is provided at the center of the surface of the disc 15. A limiting disc 20 is provided on the inner wall of the disc 15 outside the bearing 21. A linkage arm 17 is rotatably installed on the surface of the vertical plate 2 on the side of the limiting disc 20. A spring telescopic component 18 is rotatably installed on the surface of the vertical plate 2 on the side of the linkage arm 17 through a bracket. The end of the spring telescopic component 18 away from the vertical plate 2 is connected to the inner wall of the linkage arm 17.

[0030] In use, the spring telescopic member 18 is provided to apply elastic pressure to the linkage arm 17;

[0031] A limiting roller 19 is installed on the outer wall of the linkage arm 17 via a bracket, and the outer wall of the limiting roller 19 contacts the outer wall of the limiting plate 20.

[0032] In this embodiment, the yarn roller is first fitted onto the outer wall of the winding roller 16. By turning the threaded pin 26, the threaded pin 26 rotates and slides inside the nut seat 25, causing the threaded pin 26 to drive the upper pressure roller 24 to rise and fall, thus adjusting the distance between the upper pressure roller 24 and the lower pressure roller 23. When the yarn fitted onto the outer wall of the winding roller 16 is passed between the upper pressure roller 24 and the lower pressure roller 23 and then passed under the second tension roller 11 or the first tension roller 6, and the yarn is being transported and wound, the upper pressure roller 24 and the lower pressure roller 23 can roll and flatten the yarn to reduce the phenomenon of yarn bending. Then, by rotating the first handle 8 and the second handle 13, the first threaded rod 7 and the second threaded rod 12 are respectively driven to the tension seat 3. The top of the device rotates and slides, causing the first limiting seat 5 and the second limiting seat 10 to slide inside the first limiting cavity 4 and the second limiting cavity 9, respectively. This allows the height of the first tensioning roller 6 and the second tensioning roller 11 to be adjusted as needed according to the tightness of the yarn, making it easy to adjust the yarn tension. Finally, the spring telescopic member 18 applies elastic pressure to the linkage arm 17, causing the linkage arm 17 to drive the limiting roller 19 to elastically abut against the outer wall of the limiting plate 20. When the yarn on the outer wall of the winding roller 16 is unwound, the limiting roller 19 abuts against the outer wall of the limiting plate 20, thus limiting the rotation of the winding roller 16 due to inertia. This effectively reduces the loosening and falling off of the yarn on the outer wall of the winding roller 16, thereby completing the use of the yarn textile tensioner.
