[0037] Among them, the loading component includes a fixed ring 10 arranged on the other side of the processing box 2, and a fixed component is arranged inside the fixed ring 10. Both sides of the fixed ring 10 are fixedly connected with pull ropes 9. The two pull ropes 9 are installed on the outer wall of the winding shaft 7. The two winding shafts 7 are rotatably installed inside the processing box 2, and one end of the two winding shafts 7 is installed with a first motor 8.

[0038] When preparing antibacterial and dustproof composite yarn, the composite yarn is first installed on the outer wall of the feed roller 3, and one end of the composite yarn is installed in the fixing ring 10 through the fixing component, and then the two first motors 8 are started at the same time to drive the winding shaft 7 to rotate, so that the winding shaft 7 close to the fixing ring 10 rotates to unwind the pull rope 9, and the winding shaft 7 away from the fixing ring 10 rotates to reel in the pull rope 9, driving the fixing ring 10 to pass through the processing box 2 to the other side, so that the fixing ring 10 pulls the composite yarn through the processing box 2 to make it immersed in the antibacterial agent, and then the end of the composite yarn is taken out of the fixing ring 10 and installed inside the feed roller 4, and finally the antibacterial agent is added to the processing box 2 through the liquid inlet pipe 5 for processing. The loading method is simple and convenient, and the operating efficiency is improved.

[0039] like Figures 1 to 7 As shown, the fixing assembly includes a fixing plate 11 arranged inside the fixing ring 10, and two fixing plates 11 are symmetrically arranged. A pressure plate 20 is installed inside each of the two fixing plates 11. The pressure plate 20 is slidably installed inside the fixing plate 11, and a second spring 21 is arranged between the pressure plate 20 and the fixing plate 11.

[0040] When installing the composite yarn, the composite yarn is placed inside the two fixing plates 11, and the elasticity of the second spring 21 causes the pressing plate 20 to press the composite yarn outward, thereby fixing it, preventing the composite yarn from falling off from the inside when the fixing ring 10 drives the composite yarn to move, thereby improving the stability during loading.

[0041] like Figure 7 As shown, a first threaded rod 12 is rotatably installed inside the fixing ring 10, and the first threaded rod 12 is embedded in the fixing plate 11. A first bevel gear 13 is fixedly installed on the outer wall of the first threaded rod 12. A second bevel gear 14 is meshingly connected to one side of the first bevel gear 13, and a first rotating shaft 15 is fixedly installed on one end of the second bevel gear 14. A sliding groove 16 is provided on the outer wall of the first rotating shaft 15, and a slider 17 is slidably connected to the inner wall of the sliding groove 16, and the slider 17 is fixedly installed on the inner wall of the pressure rod 18.

[0042] Two threads with opposite thread directions are arranged on the outer wall of the first threaded rod 12, so as to enable the two fixing plates 11 to move in opposite directions;

[0043] When the composite yarn needs to be taken out, the pressure rod 18 is pressed into the fixed ring 10. The movement of the pressure rod 18 drives the movement of the slider 17, so that the slider 17 slides on the inner wall of the slide groove 16, forcing the first rotating shaft 15 to rotate. The rotation of the first rotating shaft 15 drives the rotation of the second bevel gear 14. The rotation of the second bevel gear 14 drives the rotation of the first bevel gear 13. The rotation of the first bevel gear 13 drives the rotation of the first threaded rod 12. The rotation of the first threaded rod 12 drives the two fixed plates 11 to move outward to loosen the composite yarn, which can be quickly loosened, thereby improving the convenience of operation.

[0044] like Figure 6 As shown, the pressure rod 18 is slidably mounted on the outer wall of the first rotating shaft 15 , and a first spring 19 is arranged inside the pressure rod 18 .

[0045] When the pressure rod 18 is pressed into the fixing ring 10, the first spring 19 is deformed by force to store elastic potential energy. When the pressure rod 18 is released, the elastic potential energy is released by the first spring 19 to reverse and reset the first rotating shaft 15, so as to quickly fix or remove the composite yarn.

[0046] like Figures 1 to 7 As shown, two pressure rods 18 are provided, and the two pressure rods 18 are respectively provided on both sides of the fixing ring 10 .

[0047] It enables workers to operate from both sides, further improving the convenience of operation.

[0048] like Figures 1 to 7 As shown, a plurality of fixing rings 10 are provided.

[0049] Multiple groups of composite yarns can be loaded at one time, thereby improving the preparation efficiency of the device.

[0050] like Figure 1 and Figure 2 As shown, the pressing assembly includes a pressing roller 22 arranged inside the processing box 2, and two pressing rollers 22 are provided. The two pressing rollers 22 are fixedly connected by a connecting plate 23, and a first movable plate 24 is fixedly installed on the top of the connecting plate 23. The internal thread of the first movable plate 24 is connected to a third threaded rod 32, and the third threaded rod 32 is rotatably installed inside the processing box 2, and a second motor 33 is installed on the bottom end of the third threaded rod 32.

[0051] When the composite yarn is installed, the third threaded rod 32 is driven to rotate by the second motor 33. The rotation of the third threaded rod 32 drives the first movable plate 24 to move downward. The movement of the first movable plate 24 drives the movement of the connecting plate 23. The movement of the connecting plate 23 drives the movement of the pressing roller 22, so that the pressing roller 22 presses down the composite yarn so that it is completely immersed in the antibacterial agent to ensure the preparation effect of the antibacterial and dustproof composite yarn.

[0052] like Figure 2 As shown, a material guide roller 25 is installed inside the processing box 2, and the material guide roller 25 is arranged below the pull rope 9.

[0054] When the third threaded rod 32 rotates, the second rotating shaft 26 is driven to rotate through the pulley set 31. The rotation of the second rotating shaft 26 drives the rotation of the second gear 30. The rotation of the second gear 30 drives the rotation of the first gear 29. The rotation of the first gear 29 drives the rotation of the second threaded rod 28. The rotation of the second threaded rod 28 drives the second movable plate 27 to move downward. The movement of the second movable plate 27 drives the guide roller 25 to move, so that the two guide rollers 25 clamp the composite yarn. When the composite yarn is soaked and wound, pressure is generated on the composite yarn through the two guide rollers 25 to discharge excess antibacterial agent.

[0055] The inner wall diameter of the first gear 29 is ten N times the inner wall diameter of the second gear 30 , and N is a positive integer.

[0056] When the first gear 29 is driven to rotate by the second gear 30 , the speed at which the second moving plate 27 moves downward is reduced.

[0060] S3: Then the pressure rod 18 is pressed into the fixing ring 10, and the movement of the pressure rod 18 drives the movement of the slider 17, so that the slider 17 slides on the inner wall of the slide groove 16 to force the first rotating shaft 15 to rotate, and the rotation of the first rotating shaft 15 drives the rotation of the second bevel gear 14, and the rotation of the second bevel gear 14 drives the rotation of the first bevel gear 13, and the rotation of the first bevel gear 13 drives the rotation of the first threaded rod 12, and the rotation of the first threaded rod 12 drives the two fixing plates 11 to move outward to loosen the composite yarn and install it to the outer wall of the receiving roller 4;

[0061] S4: The third threaded rod 32 is driven to rotate by the second motor 33, and the rotation of the third threaded rod 32 drives the first movable plate 24 to move downward, and the movement of the first movable plate 24 drives the movement of the connecting plate 23, and the movement of the connecting plate 23 drives the movement of the nip roller 22, so that the nip roller 22 presses down the composite yarn to make it completely immersed in the antibacterial agent;

[0062] S5: Finally, an antibacterial agent is added into the treatment box 2 through the liquid inlet pipe 5 to process it.

[0063] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
