Description

Technical Field

[0001] This utility model relates to the field of texturing yarn production technology, specifically a texturing yarn rolling guide device. Background Technology

[0002] A texturing machine is a textile machine that can process untwisted yarns such as polyester and polypropylene into elastic yarns with medium to low elasticity through false twisting. The yarn is wound into a core under the traction of the texturing machine's traction wheel. During the process of the traction wheel pulling the yarn, yarn deviation often occurs. Therefore, texturing machines are generally equipped with a yarn guide device to correct the yarn in real time and prevent deviation. Currently, the yarn guide device includes a bracket and rollers; the yarn is guided by the rollers before entering the traction wheel.

[0003] The existing Chinese utility model patent with publication number CN222715530U discloses a yarn guiding device for a texturing machine, relating to the field of textile processing technology. The device includes a frame base and a yarn guiding device. The yarn guiding device comprises two sliders, two springs, two rotating rods, and two yarn guiding discs. The two sliders are slidably sleeved on the surface of the guiding rods and slidably connected inside a groove. The two springs are slidably sleeved on the left and right ends of the guiding rods, with one end of each spring fixedly connected to the surface of the two sliders and the other end fixedly connected to the inner wall of the groove. When the yarn gradually moves downwards, it rotates on the surface of the rotating rods through friction with the surface of the yarn guiding discs. This prevents the yarn from rubbing against the surfaces of the two yarn guiding discs, thus avoiding yarn breakage and preventing damage to the yarn guiding discs due to friction, extending the service life of the yarn guiding discs.

[0004] The aforementioned yarn guiding device guides the yarn through a yarn guide disc. The size of the yarn guide disc is fixed, making it unsuitable for yarns of different diameters and limiting its applicability. Furthermore, the yarn guiding device typically achieves a certain tension on the yarn by staggering the installation positions of the yarn guide discs. The position of the yarn guide disc is usually adjusted by a lead screw, which requires rotating the lead screw during adjustment. This method cannot quickly adjust the position of the yarn guide disc. Utility Model Content

[0017] Beneficial effects:

[0018] (1) The elasticized wire rolling guide device, through the setting of the support spring, since the distance adjustment component at the center of the support frame is suspended at the center of the support frame through the connecting pipe, the support spring is initially in a compressed state, and the center distance adjustment component is vertically offset from the distance adjustment components on both sides of the support frame. By adjusting the strength of the current passed into the electromagnet, the magnetic strength of the electromagnet is adjusted, so as to adjust the magnitude of the upward force on the central slide groove of the support frame, thereby changing the compression of the support spring, so as to adjust the position of the distance adjustment component at the center of the support frame.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-4 This utility model provides a technical solution: a spring-loaded yarn rolling guide device, including a support frame 1, with a guide mechanism 2 disposed above the support frame 1.

[0027] Tension adjustment component 21, located inside support frame 1, is used to adjust the tension of the elastic wire. Tension adjustment component 21 includes an electromagnet 211 fixedly installed at the bottom of support frame 1 and a limiting tube 212 at the top of support frame 1. A connecting column 213 is inserted inside the limiting tube 212, and a support spring 214 is inserted outside the connecting column 213. A guide rod 215 is inserted at the top of support frame 1. Tension adjustment component 21 also includes a permanent magnet 216 fixedly installed at the bottom of distance adjustment component 22. Electromagnet 211 is fixedly installed at the center of the bottom of support frame 1. The connecting column 213 has an annular protrusion structure on its outer side. The cavity of limiting tube 212 fits into the outer edge of the annular protrusion structure of connecting column 213, and the bottom end fits into connecting column 213. Connecting column 213 and limiting tube 212 form a sliding connection. Permanent magnet 216 is fixedly installed below guide rail 221.

[0028] Specifically, the support frame 1 can limit the position of the distance adjustment component 22. The electromagnet 211 can generate a repulsive force between itself and the permanent magnet 216 after being energized, thereby applying an upward force to the distance adjustment component 22 at the center of the support frame 1. The limiting tube 212 can limit the movement direction of the connecting column 213. The bottom end of the connecting column 213 is fixedly connected to the top end of the slide groove at the center of the support frame 1. The distance adjustment component 22 at the center of the support frame 1 is suspended at the center of the support frame 1 through the connecting tube and the support spring 214 is compressed. The strength of the current flowing into the electromagnet 211 is adjusted to adjust the magnetic strength of the electromagnet 211, thereby adjusting the magnitude of the upward force on the slide groove at the center of the support frame 1, thereby changing the compression of the support spring 214, so as to adjust the position of the distance adjustment component 22 at the center of the support frame 1.

[0029] The distance adjustment assembly 22 is used to adjust the tension of the limit assembly 23 in the same group. The distance adjustment assembly 22 includes a guide rail 221 set inside the support frame 1. A slider 222 is fitted inside the guide rail 221. A connecting rod 223 is movably installed at one end of the slider 222. A transmission block 224 is movably installed at the other end of the connecting rod 223. An adjusting cylinder 225 is fixedly installed on one side of the transmission block 224. A limit frame 226 is fixedly installed at the rear end of the adjusting cylinder 225. There are three sets of distance adjustment assemblies 22, which are respectively installed at the center of the support frame 1 and on the front and rear sides. The guide rail 221 is welded from the mounting structure with grooves on both sides and metal plates at the top and bottom ends. The slider 222 and the guide rail 221 are slidably connected. The two ends of the connecting rod 223 are rotatably connected to the slider 222 and the transmission block 224, respectively. One end of the limit frame 226 is fixedly connected to the guide rail 221.

[0030] Specifically, the guide rail 221 can limit the position of the slider 222. The slider 222 is installed inside the guide rail 221 in a mirror image symmetrically. The relative position between the transmission block 224 and the guide rail 221 is adjusted by adjusting the extension and retraction of the cylinder 225. This causes the transmission block 224 to drive the connecting rod 223 to adjust the distance between the sliders 222, thereby adjusting the distance between the limiting components 23 installed inside the sliders 222, so that the distance between the limiting components 23 matches the diameter of the wire.

[0031] The limiting component 23 includes a limiting disk 231 disposed inside the distance adjustment component 22. A bearing 232 is inserted and installed on one side of the limiting disk 231, and a lead screw 233 is fixedly installed on the other side of the limiting disk 231. A limiting block 234 is movably installed on the outside of the lead screw 233, and a movable disk 235 is fixedly installed on the outside of the limiting block 234. A copper ring 236 is clamped between the movable disk 235 and the limiting disk 231. The limiting disk 231 is rotatably connected to the slider 222 through the bearing 232. The limiting block 234 is installed on the outside of the lead screw 233 through the threaded structure of the lead screw 233. The movable disk 235 is slidably connected to the limiting block 234, the lead screw 233 and the limiting disk 231. The outer surface of the copper ring 236 has an arc-shaped structure, and an annular reinforcing rib is provided at the center of the inner side of the copper ring 236.

[0032] Specifically, the limiting plate 231 can limit the position of the movable plate 235 through the lead screw 233 and the limiting block 234. The movable plate 235 can apply a certain preload to the copper ring 236 through the cooperation of the limiting block 234 and the limiting plate 231 to prevent the copper ring 236 from moving. Since the copper ring 236 has a certain deformation capacity, the pressure on both sides of the copper ring 236 can be adjusted by rotating the limiting block 234. Due to the setting of the internal reinforcing ribs of the copper ring 236, the deformation area of ​​the copper ring 236 when it is subjected to force on both sides is located on both sides of the arc structure, so as to adjust the round corner of the outer arc structure of the copper ring 236 to match the diameter of the wire.

[0033] Specifically, the model of the regulating cylinder 225 is SCA2-00-50B-70. In addition, all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0034] During operation, the center distance adjustment component 22 of the support frame 1 is suspended from the center of the support frame 1 via a connecting pipe. The support spring 214 is initially in a compressed state. The center distance adjustment component 22 is vertically offset from the distance adjustment components 22 on both sides of the support frame 1. The strength of the current flowing through the electromagnet 211 is adjusted to change the magnetic strength of the electromagnet 211, thereby adjusting the upward force on the central slide groove of the support frame 1. This changes the compression of the support spring 214, facilitating the adjustment of the position of the center distance adjustment component 22 of the support frame 1. This method allows for rapid adjustment of the wire tension. The slider 222 is installed symmetrically inside the guide rail 221. The transmission block 224 and the guide rail 221 are adjusted by regulating the extension and retraction of the cylinder 225. The relative position between 21 is used to drive the transmission block 224 to drive the connecting rod 223 to adjust the distance between the sliders 222, thereby adjusting the distance between the limiting components 23 installed in the sliders 222, so that the spacing between the limiting components 23 matches the wire diameter. Since the copper ring 236 has a certain deformation capacity, the pressure on both sides of the copper ring 236 is adjusted by rotating the limiting block 234. Due to the setting of the reinforcing ribs inside the copper ring 236, the deformation area of ​​the copper ring 236 when subjected to force on both sides is located on both sides of the arc structure, so as to adjust the round corner of the outer arc structure of the copper ring 236 to match the wire diameter, so that the copper ring 236 can fit with wires of different diameters. The distance adjustment component 22 is used to adjust the distance between the limiting components 23 to expand the applicable range.
