Description

Technical Field

[0001] The utility model relates to the technical field of textile production, in particular to a constant-pressure shock-absorbing yarn guide. Background Art

[0002] Textile machinery is a general term for various mechanical devices used to process natural or chemical fibers into desired textiles. Broadly speaking, this term also includes chemical machinery used to produce chemical fibers. Textile machinery is the means of production and the material foundation of the textile industry. Its technological level, quality, and manufacturing costs are directly related to its development. Wire guides, the yarn guiding components of textile machinery, operate in concert, working in the same horizontal and directional directions to guide multiple strands of yarn to the braiding machinery, fulfilling the yarn-to-thread process.

[0003] Since the yarn surface is not always straight during yarn manufacturing, some yarn surfaces have higher friction and some have lower friction, resulting in inconsistent yarn tension in the transmission path during yarn transmission. If the yarn tension is too high, it will cause yarn strain or even yarn breakage.

[0004] Based on this, a constant pressure shock absorbing wire guide is now provided, which can eliminate the disadvantages of the existing device. Utility Model Content

[0005] The purpose of the utility model is to provide a constant pressure shock absorbing wire guide to solve the problems in the background technology.

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0023] In one embodiment, Figure 1-Figure 3 As shown, a constant pressure shock-absorbing wire guide comprises: a base 100, the upper end of the base 100 is fixedly connected to a wire guide plate 200, a wire guide hole 201 is provided in the middle of the wire guide plate 200, a wire guide groove 202 is provided on the side of the wire guide hole 201, a groove 203 is provided on the wire guide plate 200, the groove 203 is located above the wire guide groove 202, an anti-jump wire mechanism is provided in the groove 203, and the anti-jump wire mechanism comprises a baffle 301, a rotating shaft 302 is fixedly connected to the baffle 301, the rotating shaft 302 is rotatably connected in the groove 203, and the rotating shaft 302 is rotatably connected to the groove 203. The shaft 302 is movably connected to the torsion spring 303, one end of the torsion spring 303 is fixedly connected to the wire guide plate 200, and the other end of the torsion spring 303 is fixedly connected to the fixed plate 304. The fixed plate 304 is fixed in the groove 203. When the baffle 301 is rotated, the torsion spring 303 is deformed, giving the baffle 301 a reset force, and the yarn is placed in the wire guide hole 201. After releasing the hand, the torsion spring 303 helps the baffle 301 to rotate and return to its original position, closing the connection between the wire guide hole 201 and the wire guide groove 202, thereby restricting the silk thread in the wire guide hole from leaving the wire guide hole, which has a restrictive effect on the silk thread.

[0024] In this embodiment, if Figure 2 As shown, a shock absorbing member is provided at the lower end of the base 100, and the shock absorbing member includes a damping rod 401, one end of the damping rod 401 is fixed to the lower end of the base 100, and the other end of the damping rod 401 extends into the damping cylinder 402, and the damping rod 401 is fixedly connected to a piston 403 at one end of the damping cylinder 402, and the piston 403 is provided with two through holes 404, and the outer cover of the damping rod 401 is connected to a sealing ring 405, and the sealing ring 405 is fixed to the upper end of the damping cylinder 402. The lower end of 402 is fixedly connected to the fixing seat 406, and the outer shell of the damping cylinder 402 is connected to the spring 407. One end of the spring 407 is fixed to the lower end of the base 100, and the other end of the spring 407 is fixed to the upper end of the fixing seat 406. When the base 100 moves downward, the spring 407 is compressed, and the damping rod 401 drives the piston 403 to move downward. The damping oil 408 flows through the through hole 404, slowing down the too fast movement of the piston 403, thereby maintaining the stability of the tension of the yarn on the transmission path and ensuring that the yarn is not stretched or broken.

[0025] In one embodiment, Figure 1 As shown, the lower end of the fixing seat 406 is fixedly connected to the mounting ring 500, which facilitates fixing the yarn guide on the textile machine.

[0026] In one embodiment, Figure 2 As shown, the sealing ring 405 is located above the piston 403, sealing the gap between the damping rod 401 and the damping cylinder 402 to prevent the damping oil 408 from flowing out.

[0027] In one embodiment, Figure 2 As shown, damping oil 408 is provided inside the damping cylinder 402 and is located below the sealing ring 405. The damping oil 408 increases damping through its viscosity, so that the yarn maintains a stable tension on the transmission path.

[0028] In one embodiment, Figure 1 As shown, the surface of the baffle 301 is in contact with the wire guide plate 200 , closing the connection between the wire guide hole 201 and the wire guide groove 202 , thereby restricting the wire in the wire guide hole 201 from leaving the wire guide hole 201 .

[0029] In one embodiment, Figure 3 As shown, the fixing plate 304 is perpendicular to the baffle 301, ensuring that after the baffle 301 rotates, the torsion spring 303 provides a restoring force to the baffle 301.

[0030] In one embodiment, Figure 1 As shown, the wire guide plate 200 is made of ceramic material, which has high hardness, high strength and excellent corrosion resistance.

[0031] The above embodiment discloses a constant pressure shock-absorbing yarn guide, in which the yarn guide is fixed to the textile machine by means of a mounting ring 500, the baffle 301 is rotated, the torsion spring 303 is deformed, and a reset force is applied to the baffle 301, and the yarn is placed in the wire guide hole 201. After the hand is released, the torsion spring 303 helps the baffle 301 to rotate and return to its original position, closing the connection between the wire guide hole 201 and the wire guide groove 202, thereby restricting the wire in the wire guide hole from leaving the wire guide hole, which has a restrictive effect on the wire. When the yarn is working, the base 100 is pressed down, and the base 100 moves up and down, the spring 407 is compressed and rebounds, and the damping rod 401 drives the piston 403 to move up and down in the damping cylinder 402, and the damping oil 408 flows through the through hole 404, slowing down the movement speed of the piston 403 and slowing down the too fast rebound of the spring 407, thereby maintaining the stability of the tension of the yarn on the transmission path and ensuring that the yarn is not stretched or broken.

[0032] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
