Technical Field

[0001] The utility model belongs to the technical field of textile equipment, and specifically relates to an adjustable nylon yarn guide structure. Background Art

[0002] Nylon has good wear resistance, high breaking strength, excellent resilience and fatigue resistance, and low density. It is the lightest fiber except for polyethylene and polypropylene. It is usually mixed with other fibers for warp knitting. When the yarn is transmitted, in order to ensure that the yarn is accurately placed on the knitting needle, a yarn guide is usually used to guide the yarn. However, in actual operation, the existing yarn guide cannot adjust the nylon transmission tension in real time, resulting in more wrinkles in the subsequent warp knitted fabric. In addition, when the yarn tension is abnormal, it is easy to break the yarn or curl.

[0003] In order to solve the deficiencies of the existing technology, people have conducted long-term exploration and proposed various solutions. For example, a Chinese patent document discloses a yarn guide frame [201820567821.7], which includes a frame, a yarn guide frame, a yarn guide groove, a guide roller, a tension sensor, a pulling mechanism and yarn, the yarn guide frame is arranged at the front end of the frame, the yarn guide frame is provided with a plurality of yarn guide grooves, two guide rollers are located behind the yarn guide frame and connected to the frame, a tension sensor is arranged between the yarn guide frame and the guide roller, a tension sensor is arranged between the guide roller and the pulling mechanism, and the tension sensor is connected to the frame, a pulling mechanism is arranged behind the frame, and the yarn is pulled by the pulling mechanism and comes out of the yarn guide frame and passes around the tension sensor and the guide roller in sequence.

DETAILED DESCRIPTION

[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0023] like Figure 1-4 As shown, an adjustable nylon yarn guiding structure includes a yarn guide frame body 1 assembled with a yarn guide, and a plurality of yarn guide wheels 2 are rotatably mounted on the yarn guide frame body 1, and each yarn guide wheel 2 is respectively pressed against the nylon yarn. A limit frame body 3 is movably mounted on the yarn guide frame body 1, and the limit frame body 3 has a separation plate 4 arranged between the yarn guide wheels 2, and the separation plates 4 are respectively provided with yarn guide holes 41 for the yarn to pass through, and each yarn passes through the yarn guide hole 41 and is pressed against the yarn guide wheel 2, and their transmission does not interfere with each other. A lifting component 5 is installed between the limit frame body 3 and the yarn guide frame body 1, and a swing component 6 is installed between the separation plate 4 and the yarn guide hole 41. When the swing component 6 drives the separation plate 4 to swing and adjust the orientation of the yarn guide hole 41, the yarn guide frame body 1 is lifted and lowered as a whole for adaptive adjustment.

[0024] Specifically, in order to facilitate the assembly and fixation of the yarn guide frame 1, it specifically includes a vertically arranged and long strip yarn guide plate 11, and each yarn guide wheel 2 is arranged equidistantly along the yarn guide plate 11. The upper and lower ends of the yarn guide plate 11 are respectively connected to a support plate 12 with a mounting hole through reinforcing ribs, and the yarn guide wheel 2 is movably connected to the yarn guide plate 11 through a telescopic assembly. The support plate 12 is assembled with the corresponding yarn guide through a threaded member inserted into the mounting hole.

[0025] In depth, the telescopic assembly independently adjusts the relative distance between each yarn guide wheel 2 and the yarn guide frame body 1, including an electric push rod 13 installed on the yarn guide plate 11, the telescopic end of the electric push rod 13 is perpendicular to the yarn guide plate 11, and the yarn guide wheel 2 is rotatably connected to the telescopic end of the electric push rod 13. A rotating bearing is also provided between the yarn guide frame body 1 and the telescopic end of the electric push rod 13 to improve its rotational lubricity.

[0026] Further, similar to the conventional transmission wheel structure, the yarn guide wheel 2 in the present application includes a main wheel body 21, the outer side of the main wheel body 21 is coated with a wear-resistant layer 22, the wear-resistant layer 22 is provided with a yarn guide groove 23 for yarn compression along the circumferential direction, and the side of the yarn guide wheel 2 opposite to the yarn guide plate 11 is provided with a mutually meshing locking groove 24 and a locking protrusion 25. When the telescopic assembly drives the yarn guide wheel 2 to fit with the yarn guide plate 11, the locking groove 24 and the locking protrusion 25 are meshed to achieve the locking and fixing of the yarn guide wheel 2, and the yarn stops being conducted in this state.

[0027] Furthermore, the lifting assembly 5 drives the limit frame 3 to move up and down by means of a screw transmission, and includes a lifting motor 51 installed on the yarn guide frame 1, and the output end of the lifting motor 51 is connected to a lifting screw 52, ​​and the lifting screw 52 is threadedly connected to the limit frame 3, and a limit groove 53 and a limit bar 54 extending in the vertical direction and slidably connected are installed between the end of the limit frame 3 and the yarn guide frame 1. The lifting motor 51 provides a driving torque, and when the limit frame 3 slides down, the isolation plate 4 and the yarn guide hole 41 also drop down.

[0028] In addition, the limiting frame 3 is provided with swing seats 31 corresponding to the isolation plates 4 one by one, the ends of the isolation plates 4 are rotatably connected to the swing seats 31, and the isolation plates 4 are provided with yarn guide notches 42 extending from the edges of the isolation plates 4 to the yarn guide holes 41. A notch is reserved at the lower end of the swing seats 31 for inserting the isolation plates 4, and the swing seats 31 are arranged equidistantly.

[0029] At the same time, the swing assembly 6 drives each isolation plate 4 to swing synchronously, including a swing motor 61 installed on the limit frame 3, the output end of the swing motor 61 is connected to a swing rod 62 that passes through each swing seat 31, and a swing gear 63 is fixed on the swing rod 62. The swing gear 63 is meshed with a swing toothed disk 64 installed on the isolation plate 4 for transmission. Since the transmission ratio of the swing gear 63 and the swing toothed disk 64 is different, the swing angle of each isolation plate 4 is also different.

[0030] It can be seen that in order to facilitate the quick assembly of the swing assembly 6, the swing toothed disc 64 is fixedly connected to the isolation plate 4 through a screw, and a spline is provided between the swing gear 63 and the swing rod 62. The swing toothed disc 64 and the swing gear 63 can be disassembled and replaced to adjust their transmission ratio, thereby adapting to different yarn tension adjustment requirements.

[0031] Obviously, a yarn guide block 7 corresponding to the yarn guide wheel 2 is installed on the top of the yarn guide frame 1 to gather and conduct the yarn, and a yarn inlet hole 71 is opened on the yarn guide block 7 to guide the yarn to extend vertically downward. A sensor element is usually installed on the yarn guide block 7 to sense the yarn state, and an alarm message is sent immediately when it breaks.

[0032] Preferably, the yarn inlet hole 71 extends in the vertical direction and the upper and lower ends are chamfered to protect the yarn and prevent the yarn from being broken by friction with the yarn inlet hole 71 during high-speed conduction.

[0033] To sum up, the principle of this embodiment is that the yarn guide frame 1 guides the transmission of multiple groups of yarns, wherein each yarn is respectively pressed against the yarn guide wheel 2 and passes through the isolation plate 4; when the limiting frame 3 drives the isolation plate 4 to rise and fall, the swing assembly 6 also drives the isolation plate 4 to flip and adjust the position of the yarn guide hole 41, thereby realizing flexible adjustment of the yarn tensioning force.
