Abstract
Description
Technical Field
[0001] This utility model relates to the field of textile technology, specifically to a yarn guiding device for sewing thread production. Background Technology
[0002] First, a large number of short fibers are aggregated into loose cotton thread. Then, the cotton thread is pulled out little by little and twisted into fine cotton thread. The cotton thread becomes longer after twisting. In modern spinning, a doubling machine is used to perform one of the processes.
[0003] According to the public announcement of a yarn guiding device for a yarn doubling machine for sewing thread production (Announcement No.: CN213387235U3), the above application can reduce the frequency of thread breakage when operating on the same type of thread, and the yarn guiding component can operate on multiple strands of yarn, effectively improving the practicality of the equipment.
[0004] However, in actual use, when the above-mentioned equipment guides the yarn to make contact with the guide groove on the guide seat, the yarn constantly contacts the guide groove, causing friction and breakage, which in turn affects the yarn guiding effect. In view of this, we propose a yarn guiding device for sewing thread production. Utility Model Content
[0005] The purpose of this invention is to provide a yarn guiding device for sewing thread production, so as to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a yarn guiding device for sewing thread production, comprising a bracket, a motor fixedly mounted on the side wall of the bracket, a threaded rod fixedly mounted on the output end of the motor, a sliding block being drivenly connected to the arc surface of the threaded rod, a wire seat fixedly mounted on the upper surface of the sliding block, a protective mechanism provided on the arc surface of the wire seat, and a promoting mechanism provided on the arc surface of the wire seat, the protective mechanism comprising:
[0007] The mounting groove is formed on the surface of the wire seat, and a circular hole is formed on the inner wall of the mounting groove. A return spring is fixedly connected to the inner wall of the circular hole.
[0008] A straight rod is fixedly connected to the end of the return spring away from the circular hole. A guide platform is fixedly installed at the end of the straight rod away from the return spring, and a circular protrusion is fixedly installed on the arc surface of the guide platform.
[0009] Preferably, the promoting mechanism includes a chute formed on the inner wall of the mounting groove, and a limiting rod is fixedly mounted on the arc surface of the guide platform, with a ball disposed inside the limiting rod.
[0010] Preferably, the end of the limiting rod is provided with a circular groove, and the ball is disposed inside the circular groove, allowing the ball to slide inside the circular groove.
[0011] Preferably, the surface of the guide platform is arc-shaped, which allows the yarn to pass through the conductor seat more smoothly.
[0012] Preferably, both the straight rod and the return spring are disposed inside the circular hole, so that the straight rod and the return spring can move stably inside the circular hole.
[0013] Preferably, the number of circular holes is set to several, and the several circular holes are arranged in a circumferential array on the inner wall of the mounting groove. The arrangement of multiple circular holes facilitates the installation of multiple straight rods and return springs, thereby allowing the guide platform to better buffer the impact when guiding the yarn.
[0014] Preferably, the mounting groove is adapted to the shape of the guide platform, thereby enabling the guide platform to move inside the mounting groove.
[0015] Compared with the prior art, this utility model provides a yarn guiding device for sewing thread production, which has the following beneficial effects:
[0016] 1. This yarn guiding device for sewing thread production, by setting up a protective mechanism, allows the yarn to pass smoothly through the guide platform of the guide seat, with its arc-shaped surface and circular protrusion working together; when the yarn exerts impact pressure on the guide platform, the guide platform, with the cooperation of the straight rod and the return spring, adaptively moves slightly along the circular hole, thereby effectively buffering the pressure, reducing friction, and significantly reducing the risk of yarn breakage.
[0017] 2. This yarn guiding device for sewing thread production, by setting up a promoting mechanism and a limiting rod in conjunction with a ball, allows the limiting rod to move inside the slide groove. The setting of multiple limiting rods makes the movement of the guide table more stable, ensuring the guidance of the yarn. Attached Figure Description

[0023] like Figures 1-4 As shown, this utility model provides a technical solution: a yarn guiding device for sewing thread production, including a bracket 1, a motor 5 fixedly installed on the side wall of the bracket 1, a threaded rod 2 fixedly installed at the output end of the motor 5, a sliding block 6 connected to the arc surface of the threaded rod 2, a wire seat 7 fixedly installed on the upper surface of the sliding block 6, a protective mechanism 3 provided on the arc surface of the wire seat 7, and a promoting mechanism 4 provided on the arc surface of the wire seat 7. The protective mechanism 3 includes a mounting groove 301, a round hole 302, a return spring 303, a straight rod 304, a guide platform 305, and a circular protrusion 306.
[0024] In one embodiment of this utility model, the mounting groove 301 is formed on the surface of the wire seat 7, and the inner wall of the mounting groove 301 is provided with a circular hole 302. A reset spring 303 is fixedly connected to the inner wall of the circular hole 302. A straight rod 304 is fixedly connected to the end of the reset spring 303 away from the circular hole 302. A guide platform 305 is fixedly installed at the end of the straight rod 304 away from the reset spring 303. A circular protrusion 306 is fixedly installed on the arc surface of the guide platform 305.
[0025] In addition, the promoting mechanism 4 includes a slide 401, which is formed on the inner wall of the mounting groove 301. A limit rod 402 is fixedly installed on the arc surface of the guide platform 305. A ball 403 is provided inside the limit rod 402. A circular groove is formed at the end of the limit rod 402. The ball 403 is disposed inside the circular groove and can slide inside the circular groove.
[0026] In this embodiment of the invention, the surface of the guide platform 305 is arc-shaped, allowing the yarn to pass more smoothly through the wire seat 7. The straight rod 304 and the return spring 303 are both disposed inside the circular hole 302, allowing them to move stably within the circular hole 302. Several circular holes 302 are arranged in a circumferential array on the inner wall of the mounting groove 301. The arrangement of multiple circular holes 302 facilitates the mounting of multiple straight rods 304 and return springs 303, thus allowing the guide platform 305 to better buffer the impact during yarn guidance. The shape of the mounting groove 301 matches that of the guide platform 305, enabling the guide platform 305 to move within the mounting groove 301. The end of the threaded rod 2 away from the motor 5 is rotatably connected to the side wall of the bracket 1. A crossbar is fixedly installed on the side wall of the bracket 1 to limit the movement of the sliding block 6 on the arc surface of the threaded rod 2.
[0027] In this invention, when the yarn passes through the guide platform 305 of the conductor seat 7, its arc-shaped surface works in conjunction with the annular protrusion 306 to ensure a smooth transition for the yarn. When the yarn exerts impact pressure on the guide platform 305, the guide platform 305, with the cooperation of the straight rod 304 and the return spring 303, adaptively moves slightly along the circular hole 302, thereby effectively buffering the pressure, reducing friction, and significantly reducing the risk of yarn breakage.
[0028] Furthermore, the setting of the limiting rod 402 in conjunction with the ball 403 allows the limiting rod 402 to move inside the slide groove 401. The setting of multiple limiting rods 402 makes the guide table 305 more stable when moving, ensuring the guidance of the yarn. The motor 5 drives the sliding block 6 on the threaded rod 2 to move linearly on the arc surface of the threaded rod 2, thereby moving the wire seat 7 to adjust the position of the wire and ensure the effect of the wire.
[0029] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
