The feature is that it further includes: The constant tension mechanism 200 and the limiting mechanism 300, wherein the limiting mechanism 300 further includes: The upper right side of the mounting plate 100 is fixedly connected to the lower end of the vertical fixing plate 301. The upper left side of the vertical fixing plate 301 is rotatably connected to the second rotating long shaft 302. The left and right ends of the second rotating long shaft 302 pass through and are slidably connected to the upper end of the fixing short plate 303 to facilitate the limiting of the spandex covering yarn. The upper left side of the fixing short plate 303 is fixedly connected to the semi-circular limiting block 304. A square box 311 is fixedly connected to the middle of the interior of the vertical fixing plate 301. The middle of the fixing short plate 303 is slidably connected to the inner side of the top groove of the square box 311. An adjustment mechanism 305 is provided in the middle of the inner side of the square box 311. The regulating mechanism 305 also includes: The rack 306 is fixedly connected to the right end of the fixed short plate 303 at its lower end, and the back of the left end of the rack 306 meshes with the front end of the gear 307. The rack 306 is mirror-image positioned at the front and rear of the gear 307 and is slidably connected to the inside of the square box 311. The through hole inside the gear 307 is fixedly connected to the middle of the rotating short shaft 308. The upper end of the rotating short shaft 308 is fixedly connected to a fixed turntable 309. The fixed turntable 309 is rotatably connected to the through hole in the middle of the top surface of the square box 311 to facilitate fixing the gear 307. The lower end of the rotating short shaft 308 passes through and is rotatably connected to the middle of the bottom of the square box 311. The lower end of the rotating short shaft 308 is fixedly connected to an adjustment handle 310 to facilitate adjusting the distance between the semicircular limit blocks 304. The constant tension mechanism 200 also includes: The L-shaped fixed plate 201 is fixedly connected to the upper end of the mounting plate 100 at the front center of the left side. A pneumatic push rod 202 is fixedly connected to the top surface of the L-shaped fixed plate 201. The output shaft of the pneumatic push rod 202 passes through and is slidably connected to the bottom of the upper end of the L-shaped fixed plate 201. An L-shaped mounting block 203 is fixedly connected to the end of the output shaft of the pneumatic push rod 202. The inner end of the L-shaped mounting block 203 is fixedly connected to the inner groove of the L-shaped fixed plate 201. A fixed short shaft 205 is fixedly connected to the lower part of the right side of the L-shaped fixed plate 201.

The lower left side of the L-shaped fixing plate 201 is rotatably connected to the end of the first rotating long shaft 206. The first rotating long shaft 206 is elastically connected to the hollow roller 208 through the fixing spring 207, which facilitates the hollow roller 208 to shift around the first rotating long shaft 206 as the center, thereby reducing the pressure of the compression roller 204 and the hollow roller 208 on the spandex covered yarn and preventing yarn breakage. The inner end of the fixing spring 207 is distributed in a ring shape and equidistantly on the outside of the first rotating long shaft 206 so that the hollow roller 208 can shift smoothly, and the outer end of the fixing spring 207 is fixedly connected to the inner side of the hollow roller 208.

[0018] The working principle of a constant tension winding device for spandex-coated yarn based on the above embodiments is as follows: The spandex covered yarn passes through the bottom of the first guide roller 101, through the hollow roller 208, from back to front between the hollow roller 208 and the extrusion roller 204, through the top surface of the extrusion roller 204, through the second guide roller 102 and the second rotating long shaft 302, and is wound by the winding roller 103. By rotating the adjustment handle 310 of the adjustment mechanism 305, the short shaft 308 is driven to rotate, which in turn drives the gear 307 and the fixed turntable 309 to rotate, which in turn drives the rack 306 to rotate and move, which in turn drives the fixed short plate 303 to move, thereby adjusting the distance between the semi-circular limit block 304 on the left and right sides of the second long shaft 302, thereby limiting the horizontal displacement that occurs when the spandex covered yarn is wound. The pneumatic push rod 202 output shaft pushes the L-shaped mounting block 203 to move inside the L-shaped fixing plate 201, thereby causing the extrusion roller 204 to move. This causes the extrusion roller 204 to press down on the hollow roller 208, so as to apply a constant tension to the wound spandex covered yarn. At the same time, the hollow roller 208 is offset by the fixed spring 207 on the first rotational long axis 206, thereby reducing the pressure of the extrusion roller 204 and the hollow roller 208 on the spandex covered yarn and preventing yarn breakage.

[0019] This utility model provides an improved constant tension winding device for spandex covered yarn. By setting a constant tension mechanism 200 to compress and stretch the wound spandex covered yarn, the tension fluctuation of the spandex covered yarn is reduced. By fixing the spring 207, the hollow roller 208 is displaced when it is pressed down by the extrusion roller 204, so as to avoid excessive compression of the spandex covered yarn and breakage. By setting a limiting mechanism 300, the adjustment mechanism 305 can easily adjust the distance between the semi-circular limiting blocks 304, thus limiting the horizontal displacement of the spandex covered yarn during winding.
