[0013] Further, the side wall of the ring body is provided with an adjusting air pump, and the adjusting air pump is communicated with the pressure chamber.

[0014] The yarn feeding and guiding device provided by the present application has the following beneficial effects: when the spool is fed and wound, the spool is fixed on the fixing table, the initial thread is pressed between the spool and the fixing table after passing through the thread hook, the negative pressure in the pressure chamber is adjusted by the air pump according to the specification of the yarn, then the feeding and winding are started and the electric telescopic rod is retracted to release the limitation of the thread hook, the motor drives the passive gear ring through the driving gear to rotate the winding ring, the thread hook rotates around the spool to feed, the thread hook keeps the tension of the yarn by the negative pressure adsorption piston of the adjusting rod, when the yarn is in the balanced state, the position of the adjusting rod is in the balanced state, as the feeding proceeds, the tension of the yarn changes, for example, if the winding ring rotates clockwise to feed, if the current yarn is in the tight state, it indicates that the length of the yarn from the discharge end to the feeding end is shorter than that in the balanced state, at this time, the yarn pulls out the adjusting rod outward, so that the rotation of the thread hook lags behind the rotation of the winding ring to prevent the thread hook from pulling off the yarn, if the current yarn is in the loose state, it indicates that the length of the yarn from the discharge end to the feeding end is longer than that in the balanced state, at this time, the adjusting rod is retracted into the arc tube under the action of the negative pressure of the pressure chamber, so that the rotation of the thread hook is ahead of the rotation of the winding ring to tighten the yarn and prevent the yarn from winding, when the adjusting rod extends and retracts in the arc tube, the volume change of the closed space surrounded by the pressure chamber, the arc tube and the piston is relatively small compared with the volume of the pressure chamber, so the tension change of the yarn caused by the negative pressure is small, which can provide the yarn with nearly constant tension in different states of the yarn to ensure the quality of the winding, at the same time, the tension caused by the negative pressure can be flexibly adjusted, and the height of the winding ring can be flexibly controlled by the electric control screw, which can cope with the feeding of yarns of various specifications.

[0029] Furthermore, the height adjustment mechanism 2 includes a slider 201 and a C-shaped groove 202. The slider 201 has a screw hole 206, which is threadedly engaged with the electric control screw 105. The slider 201 is slidably disposed in the slide groove 104. The C-shaped groove 202 is disposed on the side of the slider 201 away from the slide groove 104. The bottom wall of the C-shaped groove 202 has an arc groove 203. The bottom of the top wall of the C-shaped groove 202 is provided with a motor 204. The bottom of the motor 204 is provided with a drive gear 205, which is connected to the output end of the motor 204.

[0030] Furthermore, the winding ring 3 includes a ring body 301, an annular groove 304 is formed on the inner wall of the ring body 301, a pressure chamber 305 is formed inside the ring body 301, the pressure chamber 305 is arranged in a ring and surrounds the outside of the annular groove 304, an arc tube 307 is provided inside the annular groove 304, the arc tube 307 is arranged in a semi-circular shape and communicates with the pressure chamber 305, and the adjusting rod 4 is slidably arranged inside the arc tube 307.

[0031] Furthermore, the bottom of the ring body 301 is provided with a retaining ring 302, which is slidably disposed in the arc groove 203. The top of the ring body 301 is provided with a passive gear ring 303. The passive gear ring 303, the retaining ring 302 and the ring body 301 are coaxially arranged, and the passive gear ring 303 meshes with the driving gear 205.

[0032] Furthermore, the adjusting rod 4 includes an arc rod 401, a piston 402, and a hook 403. The arc rod 401 is slidably disposed inside the arc tube 307. The piston 402 is disposed at one end of the arc rod 401 located inside the arc tube 307 and is in contact with the inner wall of the arc tube 307. The hook 403 is disposed at one end of the arc rod 401 located outside the arc tube 307.

[0033] Furthermore, a boss 309 is provided on the inner side of the ring 301, and an electric telescopic rod 310 is provided at the bottom end of the boss 309. The distance from the electric telescopic rod 310 to the center of the ring 301 is the same as the distance from the hook 403 to the center of the ring 301.

[0034] Furthermore, the inner walls at both ends of the arc tube 307 are respectively provided with limiting plates 308. The inner diameter of the limiting plates 308 is smaller than the diameter of the piston 402 and larger than the diameter of the arc rod 401.

[0035] Furthermore, the side wall of the ring 301 is provided with an adjusting air pump 306, which is connected to the pressure chamber 305.

[0036] In practical use, firstly, select the corresponding fixing platform 102 according to the specifications of the spool and fix it with screws 103. Insert the spool into the protrusion of the fixing platform 102 and fix it. Then, pass the initial thread end through the hanging hook 403 and press it between the spool and the fixing platform 102. Then, adjust the negative pressure in the pressure chamber 305 according to the specifications of the yarn. Then, start feeding and winding the yarn and retract the electric telescopic rod 310 to release the limit on the hanging hook 403. The motor 204 drives the passive gear ring 303 through the active gear 205 to make the winding ring 3 rotate. The hanging hook 403 rotates around the spool to feed the yarn. The adjusting rod 4 uses the negative pressure of the pressure chamber 305 to attract the piston 402 to keep the hanging hook 403 maintaining the tension of the yarn on the yarn. The electric control screw 105 controls the height adjustment mechanism 2 to move up and down through the screw hole 206 to adjust the shape of the yarn winding. When the yarn is in a balanced state, the position of the adjusting rod 4 is in a balanced state. As feeding continues, the tension of the yarn will change to wind the yarn. Taking the clockwise rotation of the yarn loop 3 as an example, if the yarn is currently taut, it means that the length from the yarn outlet to the yarn feed end is shorter than in the balanced state. In this case, the yarn will pull the adjusting rod 4 outward, causing the rotation of the hanging hook 403 to lag behind the rotation of the winding loop 3, preventing the hanging hook 403 from breaking the yarn. If the yarn is currently loose, it means that the length from the yarn outlet to the yarn feed end is longer than in the balanced state. In this case, under the negative pressure of the pressure chamber 305... When the adjusting rod 4 retracts into the arc tube 307, the rotation of the hanging hook 403 precedes the rotation of the winding ring 3, tightening the yarn and preventing it from tangling. When the adjusting rod 4 extends and retracts within the arc tube 307, the volume change of the sealed space formed by the pressure chamber 305, the arc tube 307, and the piston 402 is relatively small compared to the volume of the pressure chamber 305. Therefore, the change in tension on the yarn caused by the negative pressure is minimal, providing a nearly constant tension to the yarn in different states.
