Description

Technical Field

[0001] This utility model relates to a tension adjustment device for antistatic blended flame-retardant yarn, belonging to the field of yarn processing technology. Background Technology

[0002] Antistatic blended flame-retardant yarn is a high-performance yarn that combines antistatic and flame-retardant properties. It is typically made by finely blending natural fibers with flame-retardant and antistatic synthetic fibers, effectively preventing static electricity buildup while providing excellent fire resistance. Its antistatic properties reduce the harmful effects of static electricity on the human body, making it particularly suitable for high-tech industries and electronic equipment manufacturing where strict static electricity control is required; while its flame-retardant function slows the spread of flames, reducing the risk of fire accidents.

[0003] Existing yarn tension regulating devices, lacking real-time yarn tension detection capabilities, cannot accurately monitor yarn tension changes or automatically adjust the position of the guide rollers. This leads to unstable yarn tension, resulting in problems such as yarn slack or excessive tension. Consequently, the uniformity and precision of the yarn during weaving or sewing are affected. Overly tight yarn may cause fabric stretching deformation or excessive wear of machine parts, while overly loose yarn may cause yarn breakage or uneven fabric surface, thereby reducing product quality and production efficiency.

[0004] To address this, a tension adjustment device for antistatic blended flame-retardant yarns is proposed. Utility Model Content

[0025] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0026] Example 1

[0027] like Figure 1-5As shown, this utility model embodiment provides a tension adjustment device for antistatic blended flame-retardant yarn, including a frame 1. Guide rollers 2 are movably connected to the left and right sides of the inner side of the frame 1. An adjustment component 3 is provided on the inner side of the frame 1. The adjustment component 3 includes a servo motor 301, a transmission gear 302, a toothed plate 303, a positioning rod 304, a tension detection device 305, an electromagnetic coil 306, a connecting rod 307, a connecting frame 308, and a guide wheel 309. The transmission gear 302 is movably connected to the rear side of the frame 1. The toothed plates 303 are located on the left and right sides of the surface of the transmission gear 302, and the two toothed plates 303 mesh with the left and right sides of the surface of the transmission gear 302. The tension detection device 305 is fixedly connected to the inner side of the positioning rod 304. The electromagnetic coil 306 is located on the inner side of the frame 1. Inside the tension detection device 305, and electrically connected to the tension detection device 305 through electrodes, the connecting rod 307 is fixedly connected to the other end of the electromagnetic coil 306, the connecting frame 308 is fixedly connected to the lower end of the connecting rod 307, and the guide wheel 309 is movably connected to the inside of the connecting frame 308 through a rotating shaft. The tension detection device 305, electromagnetic coil 306, connecting rod 307, connecting frame 308 and guide wheel 309 are all several in number and are equidistantly distributed along the inner side of the two positioning rods 304. The positioning rods 304 are bolted to the front side of the two toothed plates 303, and the two positioning rods 304 are obliquely symmetrically arranged. The servo motor 301 is fixedly connected to the inside of the frame 1, and the output end of the servo motor 301 is fixedly connected to the transmission gear 302.

[0028] By adjusting the settings of component 3, yarn tension can be detected in real time and the position of the guide roller can be automatically adjusted. This maintains the stability of yarn tension, reduces yarn breakage and equipment wear, improves production efficiency and fabric quality, reduces manual intervention, adapts to various production needs, ensures yarn uniformity and flame retardant properties, and thus improves product quality and safety.

[0029] Example 2

[0030] In one embodiment, through slots 310 are provided on both the left and right sides of the rear side of the frame 1. The positioning rod 304 extends through the through slots 310 to the inner side of the frame 1. Guide slots 311 are provided on both the left and right sides of the inner side of the through slots 310. Guide blocks 312 are fixedly installed on both the left and right sides of the positioning rod 304. The guide blocks 312 are slidably connected to the inner side of the guide slots 311. Slide grooves 4 are provided on both the left and right sides of the inner side of the frame 1. The end of the positioning rod 304 away from the toothed plate 303 is slidably connected to the inner side of the slide groove 4.

[0031] The through groove 310 ensures that the positioning rod 304 moves along a predetermined trajectory. The guide groove 311 and guide block 312 connect the toothed plate 303, improving the stability of the toothed plate 303 during movement and preventing it from falling off. The sliding groove 4 further enhances the stability of the positioning rod 304 during movement.

[0032] In operation, this invention works as follows: After the yarn passes through the surface of the guide roller 2 and below the left guide wheel 309 and above the right guide wheel 309, it can be wound up by an external winding device. During winding, the guide wheel 309 is stretched outwards due to tension. This stretching of the guide wheel 309 causes the connecting frame 308 and connecting rod 307 to move inwards, stretching the electromagnetic coil 306. The tension of the electromagnetic coil 306 changes at this time, and this change is detected by the tension detection device 305. The test is analyzed. When the tension needs to be adjusted after the test, the servo motor 301 can be started to drive the transmission gear 302 at the output end to rotate. During the rotation, the transmission gear 302 causes the tooth plates 303 on both sides to move longitudinally in opposite directions through the meshing of the teeth, which drives the positioning rod 304 to move. This causes the tension detection device 305, electromagnetic coil 306, connecting rod 307, connecting frame 308 and guide wheel 309 to move, stretching or loosening the yarn to adjust the yarn tension.

[0033] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
