A transmission roller 3 for transmitting yarn is rotatably connected to the side wall of the support plate 2. A movable plate 4 is slidably connected to the side wall of the support plate 2. A driving device for moving the movable plate 4 is provided on the side wall of the support plate 2. The driving device includes a receiving groove 19 provided on the side wall of the support plate 2. A lead screw 20 is rotatably connected to the inner wall of the receiving groove 19. A nut seat 21 is sleeved on the lead screw 20. The nut seat 21 is fixedly connected to the movable plate 4. A motor 22 for driving the lead screw 20 to rotate is fixedly installed on the support plate 2. The motor 22 is a servo motor. The output shaft of the motor 22 is connected to one end of the lead screw 20.

[0023] Tensioning rollers are rotatably connected to the side wall of the movable plate 4. The tensioning rollers include multiple arrayed roller bodies. Each adjacent roller body is fixedly connected to a partition plate 5. The number of partition plates 5 corresponds to the number of roller bodies. Each roller body includes a fixing rod 6. One end of the fixing rod 6 closest to the movable plate 4 is fixedly connected to the movable plate 4. The other two ends of the fixing rod 6 are fixedly connected to the partition plates 5 on both sides. Liftable tensioning plates 7 are provided on the upper and lower sides of the fixing rod 6. A telescopic rod is provided between the tensioning plates 7 and the fixing rod 6. Lifting devices for controlling the lifting and lowering of the tensioning plates 7 are provided on several partition plates 5.

[0024] The lifting device includes a groove 8 on the side wall of the partition plate 5. A bidirectional lead screw 9 is rotatably connected to the inner wall of the groove 8. Nut seats 10 are fitted on both the left-hand and right-hand threaded sections of the bidirectional lead screw 9. Trapezoidal blocks 11 are fixedly connected to the side walls of the nut seats 10 on both sides. A channel 23 is formed between the upper and lower tension plates 7 for the trapezoidal blocks 11 to be inserted. The side walls of the trapezoidal blocks 11 that contact the upper and lower tension plates 7 are inclined. The slope of the trapezoidal block 11 is lower at the end closer to the channel 23 than at the end farther away from the channel 23. A drive assembly for driving the bidirectional lead screw 9 to rotate is provided on the side wall of the partition plate 5.

[0025] The drive assembly includes a worm gear 12 fixedly connected to one end of a bidirectional lead screw 9. Two symmetrically distributed protrusions 14 are fixedly connected to the side wall of the partition plate 5. A worm 13 that meshes with the worm gear 12 is rotatably connected between the two protrusions 14. A knob 15 is fixedly connected to one end of the worm 13. By holding the knob 15, the worm gear 12 and the bidirectional lead screw 9 can be rotated through the worm 13. After moving the trapezoidal block 11 to a suitable position, the rotation of the worm 13 can be stopped.

[0026] The telescopic rod includes a support rod 16 fixedly connected to the surface of the fixed rod 6. A groove is provided at one end of the support rod 16 near the tension plate 7. A slide rod 17 is slidably connected to the groove. One end of the slide rod 17 is fixedly connected to the tension plate 7. An elastic element 18 is fixedly connected between the other end of the slide rod 17 and the inner wall of the groove. The elastic element 18 is a return spring. Both ends of the elastic element 18 are fixedly connected to the inner wall of the groove and the slide rod 17, respectively.

[0027] Working principle: When it is necessary to adjust the tension of the same batch of yarns as a whole, the motor 22 drives the lead screw 20 to rotate forward and backward. The forward and backward rotation of the lead screw 20 can drive the nut seat 21 to move up and down along the lead screw 20. The nut seat 21 can then drive the moving plate 4 and the entire tensioning roller fixed on the moving plate 4 to rise and fall. The tension of the yarn can be adjusted as a whole through the movement of the tensioning roller. When the tension of individual yarns in the same batch of yarns is different, the tensioning plate 7 corresponding to that yarn can be raised and lowered. By holding the knob 15, the worm gear 13 can be driven to rotate forward and backward. The forward and backward rotation of the worm gear 13 can drive the bidirectional lead screw 9 to rotate forward and backward through the worm wheel 12. The bidirectional lead screw 9 can then be adjusted through the nut seats on both sides. Nut seat 10 moves the trapezoidal blocks 11 on both sides closer or further apart. When the trapezoidal blocks 11 on both sides move closer together under the action of nut seat 10 and are continuously squeezed into the channel 23, the higher part of the slope of the trapezoidal block 11 will contact the tensioning plates 7 on the upper and lower sides. The trapezoidal block 11 can then move the tensioning plates 7 on both sides further apart. During the movement of the tensioning plates 7, the slide rod 17 will move along the slide groove. At this time, the elastic element 18 is in a stretched state. Conversely, when the trapezoidal blocks 11 on both sides move further apart, the tensioning plates 7 on the upper and lower sides can move closer together through the elastic restoring force of the elastic element 18 until they contact the surface of the trapezoidal block 11, so as to achieve targeted small-amplitude adjustment of the tension force and make the adjustment of the tension force more flexible.

All technical solutions falling within the scope of this utility model's concept are protected.
