Detailed Implementation

[0026] The application will be further described in detail below with reference to the drawings. It is necessary to point out here that the following specific embodiments are only used to further illustrate the application and cannot be understood as limiting the scope of protection of the application. Those skilled in the art can make some non-essential improvements and adjustments to the application according to the above application content.

[0027] Please refer to Figure 1 and Figure 2 , a sizing device for textile yarn of down jacket fabric, comprising a groove body 2, the yarn is intermittently transmitted through the inside of the groove body 2, a plurality of rod members 3 are uniformly arranged in the circumferential direction of the groove body 2, the rod members 3 are arranged in the form of surrounding the yarn transmission path and are hollow inside, a needle tube 4 is arranged on each of the rod members 3, a plurality of sizing holes 8 are uniformly arranged on the sharp end of the needle tube 4, and the plurality of rod members 3 can be synchronously moved radially so that the needle tube 4 pierces the yarn, and the sizing device further comprises a grouting mechanism 10 for conveying sizing liquid into the rod members 3 during the stroke of the needle tube 4 piercing the yarn.

[0028] It should be noted that the sizing device is suitable for sizing relatively thick yarn, and the diameter of the needle tube 4 is relatively small, so that the yarn will not be substantially damaged when the needle tube 4 pierces the yarn; in addition, the needle tubes 4 arranged on any two rod members 3 are staggered to avoid needle collision when piercing the yarn.

[0029] A suitable amount of sizing liquid is injected into the groove body 2, the yarn is intermittently transmitted through the inside of the groove body 2 according to a certain path, that is, the yarn stops for a certain period of time after transmitting a certain length, during the period of time when the yarn stops transmitting, the plurality of rod members 3 synchronously move radially towards the yarn so that the needle tube 4 pierces the yarn, at the same time, the grouting mechanism 10 conveys sizing liquid into the rod members 3, and then the sizing liquid is divided into each needle tube 4 and discharged through the sizing hole 8, during the stroke of the needle tube 4 piercing the yarn, part of the sizing holes 8 are always located inside the yarn so that part of the discharged sizing liquid always penetrates and diffuses directly inside the yarn, realizing the penetration of the yarn from inside and outside to ensure the sizing effect of the yarn, after the plurality of rod members 3 synchronously move radially towards the yarn to a certain stroke, the plurality of rod members 3 will be reset, after the plurality of rod members 3 are reset, the yarn transmission action is performed again, and the yarn sizing operation is performed in this way; the radial movement of the plurality of rod members 3 and the discharge of the sizing liquid from the sizing hole 8 on the needle tube 4 (equivalent to undercurrent) both promote the flow of the sizing liquid, thereby facilitating the penetration of the sizing liquid into the yarn.

[0030] Further, the sizing device further comprises a plurality of guide wheels for guiding the yarn to transmit according to a set path.

[0031] Further, the sizing device further comprises a material conveying mechanism 5 for realizing intermittent conveying of the yarn, the material conveying mechanism 5 comprising two material conveying wheels (the yarn is located between the two material conveying wheels, and a gear transmission structure is arranged between the two material conveying wheels) and a driving member (such as a stepping motor, a servo motor, etc.) for driving the two material conveying wheels to rotate intermittently in opposite directions, and the corresponding control technology for controlling the driving member to start and stop is prior art, which will not be described herein.

[0032] Further, the sizing device further comprises a sizing plate 6 for scraping off the excess sizing liquid on the surface of the yarn, the sizing plate 6 being provided with through holes (not shown in the figure) matching the thickness of the yarn, and the yarn conveying path passes through the through holes.

[0033] Please refer to Figure 1 , Figure 3 and Figure 4 , in an embodiment of the present application, the sizing device further comprises a driving mechanism 9 for realizing synchronous radial movement of the plurality of rods 3; The driving mechanism 9 comprises a first mounting member 901 arranged in the groove body 2 and a driving ring 906 arranged around the plurality of rods 3, the first mounting member 901 is provided with a first sliding groove 902 corresponding to the rod 3 in the circumferential direction, a first sliding block 903 is slidingly arranged in the first sliding groove 902, and a first return spring 904 is arranged between the first sliding block 903 and the inward end of the first sliding groove 902, the plurality of rods 3 are fixedly arranged through the corresponding first sliding blocks 903, each of the rods 3 is provided with a first wedge-shaped member 907, the inner side of the driving ring 906 is in contact with the inclined side of each of the plurality of first wedge-shaped members 907, and the driving mechanism 9 further comprises an extension member 908 for driving the driving ring 906 to move along the axial direction of the rod 3, and the extension member 908 is a waterproof electric telescopic rod.

[0034] In the embodiment, the angle is shown in Figure 3 , under the cooperation of the driving ring 906 and the first wedge-shaped member 907, the extension member 908 is extended to drive the driving ring 906 to move towards the first mounting member 901, thereby driving the plurality of rods 3 to move radially towards the yarn, and the needle tube 4 is driven to pierce the yarn, the extension member 908 is retracted to drive the driving ring 906 to move away from the first mounting member 901, and under the action of the first return spring 904, the plurality of rods 3 are reset by moving radially away from the yarn.

[0035] Further, in the embodiment, the first mounting member 901 is further provided with a wire passing hole 905 for the yarn to pass through.

[0036] Based on the previous embodiment, please refer to Figure 1 , Figure 3 and Figure 5In one embodiment of the present invention, the grouting mechanism 10 includes an annular component 1001 disposed in the tank 2. The annular component 1001 is hollow inside and is provided with a matching sealing piston 1003 (also annular). A liquid guide pipe 1002 is provided between the annular component 1001 and each rod 3. A plurality of connecting rods 1004 are provided between the drive ring 906 and the sealing piston 1003. A plurality of liquid inlets 1005 are also provided on the annular component 1001. A first one-way valve 1006 is provided at each liquid inlet 1005, allowing only external grout to enter the annular component 1001. A second one-way valve 1007 is provided on each liquid guide pipe 1002, allowing only the grout in the annular component 1001 to be discharged into the rod 3.

[0037] In this embodiment, with Figure 3 As shown in the diagram, when the telescopic component 908 extends, it drives the drive ring 906 to move towards the first mounting component 901 (i.e., multiple rods 3 move radially towards the yarn so that the needle 4 pierces the yarn), simultaneously driving the sealing piston 1003 to move towards the first mounting component 901. The slurry inside the annular component 1001 is pushed into the multiple rods 3 by the squeezing action of the sealing piston 1003, thus delivering the slurry into the rods 3 during the stroke of the needle 4 piercing the yarn. When the telescopic component 908 contracts, it drives the drive ring 906 to move away from the first mounting component 901 (i.e., multiple rods 3 move radially away from the yarn to reset), simultaneously driving the sealing piston 1003 to move away from the first mounting component 901. Under the action of negative pressure suction, part of the slurry in the tank 2 enters the annular component 1001 through the inlet 1005 for "filling", thus circulating.

[0038] Based on the previous embodiment, please refer to Figure 1 , Figures 6 to 8 In one embodiment of the present invention, the sizing device includes a repair mechanism 7 for repairing puncture holes in the yarn; The repair mechanism 7 includes a cylinder 701 rotatably disposed in the groove 2 and a reciprocating assembly for driving the cylinder 701 to reciprocate. The cylinder 701 is provided with a through-type thread channel 703 for yarn to pass through. The thread channel 703 is evenly (densely) arranged with touching protrusions 704 for contacting the yarn. The reciprocating assembly includes a second mounting member 705 disposed in the groove 2. The second mounting member 705 is provided with a second sliding groove 706. A second slider 707 capable of reciprocating sliding is engaged in the second sliding groove 706. The cylindrical wall of the cylinder 701 is provided with a spiral groove 702. The second slider 707 is provided with a drive rod 708 whose outer diameter is adapted to the groove width of the spiral groove 702. One end of the drive rod 708 away from the second slider 707 is located in the spiral groove 702. A second return spring 709 is provided between one end of the second slider 707 and the second slide groove 706. A slide rod 710 is also provided on the second slider 707. A support rod 712 is provided on the drive ring 906. A plurality of symmetrical second wedge-shaped members 713 are arranged on the support rod 712. A rolling wheel 711 is provided at the end of the slide rod 710 away from the second slider 707. The inclined sides of the plurality of second wedge-shaped members 713 can all contact and abut against the tread surface of the rolling wheel 711.

[0039] In this embodiment, when the needle tube 4 punctures the yarn, it leaves a certain needle hole in the yarn. The yarn transmission path passes through the yarn channel 703, and the touching protrusion 704 in the yarn channel 703 contacts the yarn. When the telescopic member 908 drives the drive ring 906 to move back and forth, the support rod 712 moves laterally accordingly, so that multiple second wedges 713 alternately contact and abut against the tread surface of the rolling wheel 711. Under the action of the second return spring 709, during the process of multiple second wedges 713 alternately contacting and abutting against the tread surface of the rolling wheel 711, the second slider 707 is in a state of up and down reciprocating sliding (with... Figure 6 (Explained from the angle shown), that is, the drive rod 708 is also in a reciprocating motion state. Under the action of the drive rod 708 and the spiral groove 702, the cylinder 701 is driven to rotate back and forth. When the cylinder 701 rotates back and forth, the stroking protrusion 704 in the yarn channel 703 repeatedly contacts the yarn, thereby playing the role of repeatedly rubbing the yarn in both directions, and realizing the smoothing and repair of the puncture needle holes on the yarn.

[0040] Furthermore, in this embodiment, the touch protrusion 704 is made of soft silicone material.

[0041] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
