Description

Technical Field

[0001] This utility model relates to the field of textile equipment technology, and in particular to a yarn guiding device for a doubling machine. Background Technology

[0002] In the textile industry, the doubling machine is an important piece of equipment widely used in the yarn twisting process. Twisting is a key step in yarn manufacturing, aiming to improve the strength and stability of the yarn by twisting the fibers. The performance of the doubling machine directly affects the quality of the yarn and production efficiency.

[0003] Traditional twisting machines mostly use a fixed guide roller design, meaning the distance between the rollers is not adjustable. While this design can meet basic twisting requirements to some extent, its adaptability is insufficient when dealing with yarns of different specifications and materials. Due to differences in the thickness, stiffness, and other physical properties of yarns, a fixed-gap guide roller device can hardly guarantee that all yarns maintain optimal tension and stability during the twisting process. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a thread guiding device for a twisting machine.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] This utility model discloses a thread guiding device for a doubling twister, comprising:

[0007] The main body of the doubling twister has three sets of yarn reels installed inside. A mounting frame is also installed inside the main body, and three sets of guide rollers are mounted externally to the mounting frame. These guide rollers are rotatably mounted on the outside of the mounting frame.

[0008] The wire guide assembly includes a mounting plate, a drive motor, a rotating rod, a main gear, a secondary gear, a bidirectional lead screw, two connecting rods, a wire guide roller, a support plate, and a moving block.

[0009] As a preferred embodiment of this utility model, the mounting plate is fixedly installed on the top of the body of the twisting machine. The mounting plate has an installation groove inside. The drive motor is installed on the left side of the mounting plate. The right end of the rotating rod is rotatably connected to the inner right wall of the installation groove. The left end of the rotating rod is fixedly connected to the rotating shaft of the drive motor.

[0010] As a preferred embodiment of this utility model, the main gear is fixedly installed on both outer sides of the rotating rod, the support plate is fixedly installed on both inner walls of both inner sides of the twisting machine body, and the bidirectional lead screw is rotatably installed on the top of the support plate.

[0011] In a preferred embodiment of this utility model, the top ends of the bidirectional lead screws extend into the interior of the mounting groove and are fixedly mounted with the auxiliary gears. The auxiliary gears are meshed with the main gears, and the bidirectional lead screws are movably connected to the main body of the twisting machine and the mounting plate, respectively.

[0012] As a preferred embodiment of this utility model, the outer surfaces of the threads on both sides of the bidirectional lead screw are threaded with movable blocks, and the connecting rods are fixedly installed between the movable blocks on both sides of the twisting machine body. Three guide rollers are rotatably installed on the outside of the connecting rods.

[0013] As a preferred technical solution of this utility model, the positions of the three sets of yarn wheels, the three sets of guide rollers, and the three guide rollers are respectively corresponding.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention uses a drive motor to drive the rotation of the main gear, which in turn drives the rotation of the secondary gear and the bidirectional lead screw. The rotation of the bidirectional lead screw drives the moving blocks on both sides to move simultaneously, which in turn moves the connecting rod and the guide roller. This allows for adjustment of the distance between the guide rollers. By adjusting the distance between the guide rollers, the processing requirements of different yarns can be met, making the yarn more stable and uniform during twisting. Attached Figure Description

[0021] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0022] In the attached diagram, all identical reference numerals refer to the same components.

[0023] like Figure 1-3 As shown, this utility model provides a thread guiding device for a doubling twister, comprising:

[0024] The main body 1 of the doubling machine has three sets of yarn wheels 2 installed inside. A mounting frame 3 is also installed inside the main body 1. Three sets of guide rollers 4 are mounted on the outside of the mounting frame 3 and rotate around the frame.

[0025] The wire guiding assembly includes a mounting plate 5, a drive motor 6, a rotating rod 7, a main gear 8, a secondary gear 9, a bidirectional lead screw 10, two connecting rods 11, a wire guiding roller 12, a support plate 13, and a moving block 14.

[0026] Furthermore, the mounting plate 5 is fixedly installed on the top of the body 1 of the twisting machine. The mounting plate 5 has an installation groove 15 inside. The drive motor 6 is installed on the left side of the mounting plate 5. The right end of the rotating rod 7 is rotatably connected to the right wall inside the installation groove 15. The left end of the rotating rod 7 is fixedly connected to the rotating shaft of the drive motor 6.

[0027] Furthermore, main gears 8 are fixedly installed on both outer sides of the rotating rod 7, and support plates 13 are fixedly installed on both inner walls of both sides of the twisting machine body 1. A bidirectional lead screw 10 is rotatably installed on the top of the support plate 13.

[0028] Furthermore, the top of the bidirectional lead screw 10 extends into the interior of the mounting groove 15 and is fixedly mounted with a secondary gear 9. The secondary gear 9 is meshed with the main gear 8. The bidirectional lead screw 10 is movably connected to the main body 1 of the twisting machine and the mounting plate 5 respectively.

[0029] Furthermore, both sides of the double-acting screw 10 are threaded with moving blocks 14, and connecting rods 11 are fixedly installed between the moving blocks 14 on both sides of the twisting machine body 1. Three thread guide rollers 12 are rotatably installed on the outside of the connecting rods 11.

[0030] Furthermore, the positions of the three sets of yarn rollers 2, the three sets of guide rollers 4, and the three guide rollers 12 are respectively corresponding.

[0031] Working principle: Before the main body of the twisting machine starts working, the distance between the guide rollers 12 can be adjusted according to the processing requirements of different yarns. The drive motor 6 drives the main gear 8 to rotate, which in turn drives the auxiliary gear 9 and the bidirectional lead screw 10 to rotate. The rotation of the bidirectional lead screw 10 will drive the moving blocks 14 on both sides of the outside to move simultaneously, which in turn drives the connecting rod 11 and the guide rollers 12 to move, making it easy to adjust the distance between the guide rollers 12. By adjusting the distance between the guide rollers 12, the processing requirements of different yarns can be adapted, making the yarn more stable and uniform during the twisting process.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
