The other end of the wedge block 18 is set to a triangular inclined surface structure 20 and the triangular inclined surface structure 20 extends into the through groove 16. The triangular structure of the wedge block 18 is an equilateral triangle structure, which is convenient for the cotton yarn rod 10 to be pressed into the receiving groove 17 when it contacts the triangular inclined surface. The wedge block 18 is connected to a driving handle 21 placed outside the matching disk 15. The cotton yarn rod 10 is provided with a wedge-shaped hole 22 that matches the wedge block 18. The wedge-shaped hole 22 matches the wedge block 18, so that the wedge block 18 can lock and clamp the cotton yarn rod 10 in the two-side directions of the cotton yarn rod 10;

[0036] The driving handle 21 is provided with a plurality of groups of anti-skid rubber particles 23.

After contacting the triangular inclined surface of the wedge block 18, the wedge block 18 is driven to move toward the bottom of the accommodating groove 17, and the spring 19 is compressed at the same time. When the wedge-shaped hole 22 on the cotton yarn rod 10 reaches the position of the wedge block 18, under the action of the spring 19, the wedge block 18 is inserted into the wedge-shaped hole 22. The two groups of wedge blocks 18 lock and clamp the cotton yarn rod 10. When unlocking is required, it is only necessary to push the driving handle 21 so that the triangular inclined surface structure 20 of the wedge block 18 is disengaged from the wedge-shaped hole 22 on the cotton yarn rod 10, thereby realizing the disengagement of the cotton yarn rod 10. The present embodiment facilitates the replacement of the cotton yarn rod 10 and is stable and reliable during rotation.

[0038] Embodiment 3, on the basis of embodiment 1, the dust collecting device 14 includes a mounting hole 24 opened on the partition 12, the mounting hole 24 is a rectangular frame structure, an air inducer is installed in the mounting hole 24, the air inducer includes a bypass pipe 25 installed on the partition 12, and a circumferentially closed bypass pipe 25 is installed in the mounting hole 24 along its inner frame direction, the bypass pipe 25 is extended through the inner edge line of the mounting hole 24 and is in a closed state in the circumference, and an overflow cutout 26 is opened in the bypass pipe 25 along its bypass direction, the overflow cutout 26 is formed by the open ends of the bypass pipe 25 staggered with each other, the direction of the overflow cutout 26 is set in the direction away from the center of the bracket 1, and the overflow cutout 26 is also extended along the inner edge line of the mounting hole 24. The cut is formed due to the staggered ends of the bypass pipe 25. From the cross-sectional direction, it can be obviously seen that the bypass pipe 25 meets the requirements. Aerodynamic design, one side is wider and the other side is narrower, the inner side has a straight transition, and the outer side has a smooth transition, ensuring that the wind in the duct can smoothly flow out through the overflow cutout 26, thereby forming a wind ring and forming a negative pressure, thereby increasing the ventilation volume. This principle is similar to the principle of a bladeless fan. The absence of blades greatly increases the safety of the system and increases the throughput by several times, quickly sucking the generated dust into the center of the bypass duct 25. A base 27 is installed at the lower end of the mounting hole 24, and a turbine and a motor are installed in the base 27. The base 27 is connected to the bypass duct 25 through a connecting pipe. The turbine and the motor are connected. The motor drives the worm gear to work, and then the wind is transported to the bypass duct 25 through the turbine. An air inlet hole is set on the base 27 for air intake. The direction of the turbine operation is to introduce wind into the bypass duct 25.

[0039] A dust hood 28 arranged on one side of the air outlet of the bypass duct 25 is installed on the rear end surface of the mounting hole 24. The opening of the dust hood 28 is larger than the inner circle of the mounting hole 24. The dust hood 28 is used to collect the wind mixed with dust sucked into the mounting hole 24. The opening of the dust hood 28 is larger than the inner circle of the rectangular frame to ensure that the inner circle of the rectangular frame can be fully covered so that the wind in the bypass duct 25 can all enter the dust hood 28. A gap is left between the dust hood 28 and the end of the mounting hole 24. The gap is to ensure pressure balance. The gap should not be too large to prevent wind from flowing out from the gap. In order to reduce the effect of dust collection, the motor and the controller are electrically connected. When this embodiment is in use, the controller drives the motor to drive the turbine to work, and the wind is introduced into the base 27 through the air inlet hole. The wind enters the bypass duct 25 from the connecting pipe, and a negative pressure wind zone is formed in the bypass duct 25. Then the wind is introduced into the dust collecting hood 28. Since there are no fan blades, dust and cotton wool will not be hung on the fan blades, so that the dust and cotton wool can be concentrated in the dust collecting hood 28, and then discharged to the outside of the bracket 1 through the dust collecting pipe 29, thereby achieving the purpose of dust removal.

[0040] When the utility model is used, the cotton yarn rolls to be classified are firstly sleeved on the cotton yarn rod 10. After the sleeve is sleeved, the two ends of the cotton yarn rod 10 are placed between the two sets of driving sprockets 4 in the same longitudinal direction. The cotton yarn rod 10 is clamped between the two sets of driving sprockets 4 by the clamping device 11, and the cotton yarn rod 10 is placed between the two sets of matching disks 15. One end of the cotton yarn rod 10 moves toward the center direction of the matching disk 15 through the through groove 16. After contacting the triangular inclined surface of the wedge block 18, the driving wedge block 18 is driven. The block 18 moves toward the bottom of the accommodating groove 17, and the spring 19 is compressed at the same time. When the wedge-shaped hole 22 on the cotton yarn rod 10 reaches the position of the wedge-shaped block 18, under the action of the spring 19, the wedge-shaped block 18 is inserted into the wedge-shaped hole 22. The two sets of wedge blocks 18 lock and clamp the cotton yarn rod 10. When unlocking is required, it is only necessary to push the driving handle 21 so that the triangular inclined surface structure 20 of the wedge-shaped block 18 is disengaged from the wedge-shaped hole 22 on the cotton yarn rod 10, and the cotton yarn can be unlocked. The disengagement work of the rod 10, this embodiment is convenient for the replacement of the cotton yarn rod 10, and is stable and reliable during the rotation process. When dust removal work is needed, the two sets of driving motors 30 will be turned on by the controller to work, driving the two sets of chains 6 to rotate. The rotation of the chain 6 causes the two sets of driving sprockets 4 to rotate, thereby driving the cotton yarn rod 10 to rotate, and the cotton yarn on the cotton yarn rod 10 with cotton yarn is wound on the cotton yarn roll of the adjacent cotton yarn rod 10. During the winding process, the wound cotton yarn is dusted by the dust suction device 14, and the controller drives the motor to drive the turbine to work, and the wind is introduced into the base 27 through the air inlet hole. The wind enters the bypass pipe 25 from the connecting pipe, and a negative pressure wind zone is formed in the bypass pipe 25. Then the wind is introduced into the dust collecting cover 28. Due to the absence of fan blades, dust and cotton wool will not be hung on the fan blades, so that the dust and cotton wool can be concentrated in the dust collecting cover 28, and then discharged to the outside of the bracket 1 through the dust collecting pipe 29, thereby achieving the purpose of dust removal.

[0041] When in use, the utility model places the rolled cotton yarn on the placing plate 3 for display, and the cotton yarns of different specifications can be placed on the two placing plates 3 respectively, so as to achieve the purpose of classified storage, and the purpose of dust removal is achieved along with the winding of the cotton yarn rolls, so as to ensure the storage and display effects, the placing process is simple and convenient to operate, and the dust removal process does not involve fan blades, so as to avoid the adhesion of dust and cotton wool, the dust removal effect is ideal, the practicability is strong, and it is suitable for promotion.
