AI Technical Summary
The existing air jet loom yarn guide mechanism is inconvenient to fix, and it is difficult to adjust the tightness of the internal yarn, which may cause too much force during the winding process to cause the yarn to break.
A yarn guide mechanism including a guide mechanism and a limiting mechanism is designed. By combining a carrier spring and a guide roller, the yarn is adjusted to prevent too fast tension; the limiting mechanism prevents excessive rotation of the threaded rod by the combination of the bending plate and the rubber plate, and prevents excessive tension of the yarn.
It effectively prevents the yarn from being tightened too quickly during the adjustment process and causes breakage, while ensuring that the yarn is suitable during the winding process, improving weaving efficiency and product quality.

DETAILED DESCRIPTION
[0022] like Figure 1-Figure 4As shown, the utility model provides a technical solution: a yarn guiding mechanism of an air-jet loom for producing towels, comprising a sleeve plate 1, a support block 2 is slidably connected to the inner wall of the sleeve plate 1, a threaded rod 3 is rotatably connected to the bottom wall of the support block 2, the support block 2 can be moved upward by twisting the threaded rod 3, the threaded rod 3 is connected to the internal thread of the sleeve plate 1, a guide mechanism 4 is arranged inside the support block 2, and a limiting mechanism 5 is arranged inside the support block 2.
[0023] In this embodiment, a guide mechanism 4 is provided inside the support block 2. Through the setting of the load-bearing spring 42 in the guide mechanism 4, the support rod 41 can drive the guide roller 44 inside the fixed frame 43 to move downward during the adjustment process, so that the guide roller 44 has a certain adjustment distance for the yarn during the adjustment process, thereby preventing the yarn from being tightened too quickly and causing breakage.
[0024] In this embodiment, a limiting mechanism 5 is provided inside the support block 2. When the bottom end of the bent plate 53 in the limiting mechanism 5 is squeezed by the support rod 41 during the adjustment process, the bent plate 53 can drive the rubber plate 54 to move in the direction of the threaded rod 3 to squeeze the outer wall of the threaded rod 3, so that the threaded rod 3 cannot continue to rotate, thereby preventing the guide roller 44 from continuing to move upward and causing the yarn to be too tight and break.
[0025] The above-mentioned guiding mechanism 4 includes a supporting rod 41, which passes through the interior of the supporting block 2. A load-bearing spring 42 is sleeved on the outer wall of the supporting rod 41, one end of the load-bearing spring 42 is fixedly connected to the bottom wall of the supporting block 2, and the other end of the load-bearing spring 42 is fixedly connected to the outer wall of the supporting rod 41. Through the setting of the load-bearing spring 42, the supporting rod 41 can drive the guide roller 44 inside the fixed frame 43 to move downward to prevent the yarn from being quickly tightened and broken during the adjustment process. A fixed frame 43 is fixedly installed at the end of the supporting rod 41. The guide roller 44 inside the fixed frame 43 is driven upward by the support block 2 to tighten the internal yarn. The inner wall of the fixed frame 43 is rotatably connected to the guide roller 44, and the yarn is guided by passing through the top of the guide roller 44. A push plate 45 is fixedly installed at the end of the supporting rod 41.
[0026] The above-mentioned limiting mechanism 5 includes a rotating rod 51, which is rotatably connected to the inner wall of the support block 2, and a torsion spring 52 is sleeved on the outer wall of the rotating rod 51, one end of the torsion spring 52 is fixedly connected to the inner wall of the support block 2, and the other end of the torsion spring 52 is fixedly connected to the outer wall of the rotating rod 51. A bent plate 53 is fixedly installed on the outer wall of the rotating rod 51, and the end of the bent plate 53 is located at the bottom of the push plate 45. The push plate 45 moves downward to squeeze the bottom end of the bent plate 53, so that the bent plate 53 can drive the rubber plate 54 on the outer wall to rotate around the rotating rod 51, and a rubber plate 54 is fixedly installed on the outer wall of the bent plate 53. The bent plate 53 drives the rubber plate 54 to move in the direction of the threaded rod 3 to squeeze the outer wall of the threaded rod 3, so that the threaded rod 3 cannot continue to rotate, thereby preventing the guide roller 44 from continuing to move upward and causing the yarn to be too tight and broken. The rubber plate 54 is set to be semicircular, and the rubber plate 54 is located on the side of the threaded rod 3.
[0027] The threaded rod 3 is then rotated to move the support block 2 upward, thereby causing the support block 2 to drive the guide roller 44 inside the fixed frame 43 to move upward to tighten the internal yarn. The support rod 41 is configured with the load-bearing spring 42 to drive the guide roller 44 inside the fixed frame 43 to move downward to prevent the yarn from being quickly tightened and broken during the adjustment process. At the same time, during the adjustment process, the support rod 41 drives the push plate 45 on the bottom wall to move downward, and then the push plate 45 moves downward to squeeze the bottom end of the bent plate 53, thereby causing the bent plate 53 to drive the rubber plate 54 on the outer wall to rotate around the rotating rod 51, and then the bent plate 53 drives the rubber plate 54 to move in the direction of the threaded rod 3. Finally, the threaded rod 3 is squeezed by the rubber plate 54, so that the threaded rod 3 cannot continue to rotate, thereby preventing the guide roller 44 from continuing to move upward, causing the yarn to be too tight and broken. After the adjustment is completed, it is convenient to guide and transmit the yarn.
[0028] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
