[0002] Warping is an important step in weaving. Its purpose is to arrange a certain number of cheese yarns into a certain width according to the designed length, and wind them parallely onto the warping beam or weaving beam to prepare for the warp yarn system that constitutes the fabric. In the process of the yarn being drawn out from the creel and wound onto the warping beam, a certain tension needs to be applied to the yarn so that the yarn can be wound onto the warping beam more evenly.

[0003] To this end, the Chinese patent technical document with announcement number CN219314248U discloses a yarn tension adjustment device, including a workbench, on which four yarn guide mechanisms are installed, a primary tension adjustment mechanism is installed between the two yarn guide mechanisms in the middle, and a secondary tension adjustment mechanism is installed between the two yarn guide mechanisms on both sides. The primary tension adjustment mechanism is arranged in the same manner as the secondary tension adjustment mechanism, and the height of the primary tension adjustment mechanism is higher than the two secondary tension adjustment mechanisms.

[0004] In the above technical solution, the yarn drawn out from the creel is supported mainly by adjusting the lifting and lowering of the roller to achieve adjustment of the yarn tension. However, the adjustment range of the yarn tension by only adjusting the lifting and lowering of the roller is limited. Summary of the Invention

[0018] like Figures 1 to 3 As shown, the utility model discloses a tension adjustment device of a segmented warping machine, comprising a frame 1, a symmetrical frame connecting flange 101 is provided on the frame 1, a mounting plate 2 is provided between the frame connecting flanges 101 on both sides, one end of the mounting plate 2 is rotatably connected to the frame connecting flanges 101 on both sides, and the other end is an extended end, a symmetrical machine base 3 is provided on the mounting plate 2, and a liftable adjusting roller 4 is provided between the machine bases 3 on both sides, a circumferential adjusting device is provided on the frame 1, the circumferential adjusting device is used to drive the mounting plate 2 to rotate with the connection with the frame connecting flange 101 as the rotation center, when the tension of the yarn led out from the creel upstream is adjusted, the mounting plate 2 is driven to rotate by the circumferential adjusting device to realize the adjustment roller 4 supporting the yarn in the circumferential direction, and the adjustment roller 4 can be lifted and lowered along the machine base 3 to realize the adjustment of the linear direction of the adjustment roller 4, so that the adjustment roller 4 can adjust the tension of the yarn at more angles, thereby expanding the adjustment range of the yarn tension and improving the flexibility of use.

[0019] In this embodiment, the specific structure of the circumferential adjustment device includes a mounting seat 51, which is fixed to the frame 1, and a mounting cavity 511 is provided in the mounting seat 51. A first screw 52 is rotatably connected in the mounting cavity 511. Guide grooves 512 are provided on both sides of the mounting seat 51. A connecting block 53 that can be threadedly matched with the first screw 52 is sleeved on the outer periphery of the first screw 52. Connecting rods 54 extending toward the guide grooves 512 are provided on both sides of the connecting block 53. The connecting rods 54 are coupled to the guide grooves 512. A mounting plate connecting flange 21 is symmetrically provided at the bottom of the mounting plate 2. A push rod 55 is provided between the mounting plate connecting flange 21 and the connecting rod 54. One end of the push rod 55 is rotatably connected to the mounting plate connecting flange. 21, one end is rotatably connected to the connecting rod 54, wherein one end of the first screw 52 extends outside the mounting cavity 511 to facilitate the installation of the corresponding rotating handwheel, and the connecting rod 54 is coupled with the guide groove 512 to play a guiding role when the connecting block 53 moves. Therefore, by rotating the first screw 52, the connecting block 53 which is sleeved on the outer periphery of the first screw 52 and forms a threaded fit can move along the direction of the first screw 52 as the first screw 52 rotates. As the connecting block 53 moves, it can drive the push rod 55 to pull the mounting plate 2 to rotate with the connection with the frame connecting flange 101 as the rotation center, thereby realizing the circumferential adjustment of the adjusting roller 4.

[0020] In this embodiment, a downwardly recessed connecting groove 22 is provided on the mounting plate 2, and a bidirectional screw 6 is rotatably connected in the connecting groove 22. The machine bases 3 on both sides are respectively mounted on the two ends of the bidirectional screw 6 and respectively form a threaded fit. The machine base 3 is coupled with the connecting groove 22, and one end of the bidirectional screw 6 extends outside the connecting groove 22 to facilitate the connection of the corresponding rotating handwheel, and the machine base 3 is coupled with the connecting groove 22, which can play a guiding role when the machine base 3 moves. Therefore, by rotating the bidirectional screw 6, the machine bases 3 that are respectively mounted on the two ends of the bidirectional screw 6 and respectively form a threaded fit can move toward or away from each other along the direction of the bidirectional screw 6, so that the distance between the machine bases 3 on both sides can be adjusted, thereby facilitating the installation of the adjustment roller 4.

[0021] In this embodiment, the structure for lifting and lowering the adjusting roller 4 is that a mounting groove 31 with a notch facing the adjusting roller 4 is further provided on the machine base 3, and a second screw 7 and a guide rod 8 are respectively provided in the mounting grooves 31 on both sides. The outer periphery of the second screw 7 and the outer periphery of the guide rod 8 are respectively provided with a first mounting block 9 that can form a threaded fit with the second screw 7 and a second mounting block 10 that forms a guide fit with the guide rod 8. The first mounting block 9 and the second mounting block 10 are respectively coupled to the mounting grooves 31 on both sides, and one end of the second screw 7 extends outside the mounting groove 31 to facilitate connection with the corresponding rotating handwheel. Therefore, by rotating the second screw 7, the first mounting block 9 that is mounted on the outer periphery of the second screw 7 and forms a threaded fit with the second screw 7 can move along the direction of the second screw 7 as the second screw 7 rotates. During the movement of the first mounting block 9, the second mounting block 10 can slide along the guide rod 8, thereby guiding the movement of the first mounting block 9. The structure for connecting the adjusting roller 4 to the machine base 3 is that the first mounting block 9 and the second mounting block 10 are both rotatably connected with a sleeve 11 on the side facing the adjusting roller 4. The sleeve 11 is used to be sleeved on the end of the adjusting roller 4. After the sleeve 11 is sleeved on the end of the adjusting roller 4, the adjusting roller 4 can be fixed by the friction generated between the two. Therefore, by connecting the adjusting roller 4 with the first mounting block 9 and the second mounting block 10, the connection with the machine base 3 can be achieved. In this way, the adjusting roller 4 can be raised and lowered with the movement of the first mounting block 9 and the second mounting block 10. After the sleeve 11 is sleeved on the end of the adjusting roller 4, the machine bases 3 on both sides can be driven to move toward each other by rotating the bidirectional screw 6 to limit the axial position of the adjusting roller 4, thereby ensuring the stability of the adjusting roller 4 after installation. Similarly, by rotating the bidirectional screw 6 to drive the machine bases 3 on both sides to move away from each other, the end of the adjusting roller 4 can be pulled out from the sleeve 11, thereby facilitating the disassembly of the adjusting roller 4.

[0022] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
