[0016] III) Beneficial effects:

[0017] Compared with the prior art, the sample yarn auxiliary dyeing device has the following beneficial effects:

[0018] 1. The utility model connects the two ends of the yarn to the pressure rod and the round rod respectively, and then the sample yarn can be wound when the center column rotates relative to the end plate. The power telescopic rod controls the center column to move downward to immerse the yarn wound on the center column into the dye solution in the dye box, and then controls the center column to reverse, so that the yarn on the surface of the center column gradually relaxes. The relaxed yarn can fully contact with the dye, and then the yarn is wound around the surface of the center column while the center column continues to rotate, thereby reducing the tension on the yarn and effectively preventing the yarn from being deformed.

[0019] 2. The utility model uses the pressure telescopic rod and the slot. When the center column moves downward to make the pressure telescopic rod contact the bottom surface of the dye box, the pressure telescopic rod initially rotates with the end plate, and the pressure telescopic rod enters the slot, which can ensure that the end plate will not rotate relative to the center column.

[0020] 3. The utility model uses an inner toothed disc, teeth installed on the inner side and a spring telescopic rod. The spring telescopic rod pushes the teeth to engage with the inner toothed disc. After the central column tightens the yarn, when the worm wheel continues to rotate, the worm wheel drives the spring telescopic rod to be dislocated relative to the tooth-groove structure of the inner toothed disc. At this time, the spring telescopic rod continuously expands and contracts to ensure that the central column does not exert a large pulling force on the yarn, thereby preventing the yarn from being deformed due to the large pulling force.

[0029] like Figure 1-6As shown, the utility model provides a technical solution: a sample yarn auxiliary dyeing device, comprising a dye box 1 and a movable frame 2, the movable frame 2 is located above the dye box 1, the bottom surface of the movable frame 2 is fixedly connected to two power telescopic rods 3, the lower ends of the two power telescopic rods 3 are respectively fixedly connected to the left and right sides of the dye box 1, a central column 8 is arranged inside the dye box 1, the outer surface of the central column 8 is rotatably sleeved with two end plates 4, the two end plates 4 are fixedly connected by a round rod 14, the bottom surface of the end plate 4 located below is fixedly connected to a pressure telescopic rod 10, the inner bottom wall of the dye box 1 and located below the central column 8 are provided with a plurality of card slots 11, the pressure telescopic rod 10 is inserted into the card slot After being inserted into the groove 11, it can be ensured that the center column 8 rotates in an offset manner with the end plate 4, so that the center column 8 can stably wind and release the yarn. The distance between the slot 11 and the center column 8 is equal to the distance between the pressure telescopic rod 10 and the center column 8. Multiple slots 11 are distributed in a circular array around the axis of the center column 8. Multiple half plates 5 are arranged between the two end plates 4. The half plate 5 located on the left side of the center column 8 is fixedly connected with the adjacent half plate 5 located on the right side of the center column 8 by two bolts. The end plate 4 and the half plate 5 are both perforated structures, and the half plate 5 is a semi-disc structure. By controlling the number of half plates 5, different numbers of sample yarns can be dyed, and the upper surface of the center column 8 rotates to penetrate the bottom surface of the movable frame 2.

[0030] A power structure 7 is installed on the surface of the movable frame 2. The power structure 7 includes a power box 701, a transverse axis 702, a worm wheel 703 and a worm 704. The movable frame 2 is rotatably sleeved on both ends of the transverse axis 702. The power box 701 is fixedly connected to the right side of the movable frame 2. The worm 704 is fixedly sleeved on the outer surface of the transverse axis 702. The worm wheel 703 is meshed with the worm 704. The right end of the transverse axis 702 is fixedly connected to the output end of the power box 701. The power box 701 can drive multiple transverse axes 702 to rotate synchronously. The power box 701 can drive the transverse axes 702 to rotate forward and backward. The power structure 7 is connected to the upper end of the central column 8 through a buffer structure 6. The buffer structure 6 includes an inner toothed disc 601 and teeth 602. The inner toothed disc 601 and the central column 8 is fixedly connected, the lower end of the worm wheel 703 is rotatably inserted into the upper surface of the inner toothed disk 601, the teeth 602 are meshed with the inner ring surface of the inner toothed disk 601, the teeth 602 are connected to the circumferential side of the worm 704 through the spring telescopic rod 603, the inner ring surface of the inner toothed disk 601 is a plurality of tooth-groove structures, the number of teeth 602 on the inner side of the inner toothed disk 601 is multiple and distributed in an array around the axis of the inner toothed disk 601, after the central column 8 is tightened around the yarn, when the worm wheel 703 continues to rotate, the teeth 602 and the tooth-groove structures of the inner toothed disk 601 are misaligned, and at the same time, the spring telescopic rod 603 is continuously compressed, and the maximum pulling force of the central column 8 on the yarn is limited, which effectively prevents the yarn from being deformed by a large pulling force and causing yarn damage.

[0031] The circumferential surface of the center column 8 is connected with a pressure rod 9 by bolts. A groove 13 is opened on the circumferential surface of the center column 8. The pressure rod 9 is located inside the groove 13. The shape of the groove 13 is V-shaped. One end of the yarn is connected to the round rod 14, and then the other end of the yarn is located between the pressure rod 9 and the groove 13. The bolts are turned to push the pressure rod 9 to press the yarn, and the two ends of the yarn are pressed. When the center column 8 rotates forward and backward, the yarn can be wound and unwound.

[0032] The bottom surface of the movable frame 2 and the left and right sides of the dye box 1 are fixedly connected with a stabilizing rod 12. The dye box 1 is slidably sleeved on the outer surface of the stabilizing rod 12. When the power telescopic rod 3 drives the movable frame 2 to move up and down, it drives the stabilizing rod 12 to slide on the side of the dye box 1, thereby stably ensuring the movable frame 2 to move up and down.

[0033] Working principle: connect one end of the sample yarn to the round rod 14, place the other end of the yarn between the pressure rod 9 and the center column 8, then push the pressure rod 9 and the groove 13 by turning the bolt to clamp the yarn, start the power box 701 to drive the multiple horizontal shafts 702 to rotate, the worm 704 drives the teeth 602 to move the inner gear plate 601 by meshing with the worm wheel 703, so that the center column 8 winds the yarn to the surface, and the power telescopic rod 3 drives the center column 8 to move downward by pulling the movable frame 2, and immerses the yarn wound on the center column 8 into the dye solution in the dye box 1. When the center column 8 moves downward to make the pressure telescopic rod 10 contact with the bottom surface of the dye box 1, the pressure telescopic rod 10 is pressed against the bottom surface of the dye box 1. When the rod 10 initially follows the rotation of the end disk 4, the pressure telescopic rod 10 enters the slot 11, which can ensure that the end disk 4 will not rotate relative to the center column 8. Then, the power box 701 is used to control the center column 8 to reverse, so that the yarn on the surface of the center column 8 gradually relaxes. The relaxed yarn can fully contact the dye. Then, as the center column 8 continues to rotate, the yarn is wound around the surface of the center column 8. After the center column 8 tightens the yarn, when the worm gear 703 continues to rotate, the worm gear 703 drives the spring telescopic rod 603 to be dislocated relative to the toothed structure of the inner tooth disk 601. At this time, the spring telescopic rod 603 continues to expand and contract, ensuring that the center column 8 does not exert a large pulling force on the yarn.
