Description

Technical Field

[0001] The utility model relates to the technical field of polyester yarn winding, in particular to a polyester yarn anti-breakage winding mechanism. Background Art

[0002] In the textile production process, polyester yarn winding is a key step. Traditional winding devices are prone to polyester yarn breakage due to uneven tension or mechanical failure, affecting production efficiency and product quality.

[0003] In Chinese Patent 202322502347.3, the utility model relates to the field of polyester yarn manufacturing technology and discloses a polyester yarn anti-fracture winding structure. The utility model includes a turntable with two rotating rollers symmetrically arranged on the turntable. The rollers rotate through bearings embedded in the turntable, and a ball bearing is embedded in the rear end face of the turntable, and a threaded rod is embedded in the inner ring of the ball bearing. In this way, the threaded rod can rotate relative to the turntable, and the polyester yarn is interlaced and wound around the two rollers and then wound onto the polyester yarn winding drum. The utility model is to draw out the polyester yarn through the cooling and forming of the polyester yarn through the two rollers and then be wound onto the polyester yarn winding drum. When the tightness of the polyester yarn changes, the corresponding traction force will be applied to the turntable through the rollers, thereby causing the turntable to rotate accordingly.

[0004] The existing anti-break winding mechanism for polyester yarn adapts to the tension change of polyester yarn by the back-and-forth rotation of the turntable to prevent it from breaking. However, the tension must first be converted into the rotation of the turntable before it can be buffered. If the polyester yarn is not adjusted or relaxed in time, the polyester yarn is very easy to break. The existing device uses an elastic rope for buffering. Long-term back-and-forth pulling will cause the elastic rope to wear, the elasticity to decrease, and the adjustment effect will also decrease.

[0026] Example 1

[0027] like Figure 1 As shown, a polyester yarn anti-breakage winding mechanism includes a winding device base plate 1, a polyester yarn anti-breakage buffer component 2 is installed on the top of the winding device base plate 1, and a polyester yarn guide component 3 is provided on the side of the polyester yarn anti-breakage buffer component 2, and a polyester yarn winding component 4 is provided on the other side of the polyester yarn guide component 3.

When the silk thread is tight, the silk thread can pull the first U-shaped holder 205 to shrink downward, reduce the height difference between the downward pressing holders 213 on both sides, and then buffer the silk thread to prevent the silk thread from being too tight and causing breakage. A buffer spring 202 is arranged under the U-shaped holder to facilitate real-time adaptive adjustment according to the state of the silk thread. The structure is simple and the adjustment is timely, which is convenient for preventing the polyester silk thread from being too tight and causing breakage.

[0029] like Figure 5As shown, a polyester yarn anti-breaking winding mechanism, the polyester yarn guide component 3 includes a guide chute 301, the outer wall of the guide chute 301 is installed with a first servo motor 302, and the output end of the first servo motor 302 is fixedly connected to a ball screw 303, and the external thread of the ball screw 303 is connected to a ball nut 304, the top of the ball nut 304 is fixedly connected to a support vertical rod 305, and the top of the support vertical rod 305 is fixedly connected to a polyester yarn guide ring 306, the ball screw 303 is connected to the support through the ball nut 304. The vertical support rod 305 constitutes a transmission structure, and the polyester yarn guide ring 306 forms a sliding structure with the guide groove 301 through the vertical support rod 305. The ball screw 303 and the ball nut 304 cooperate with each other to move the polyester yarn guide ring 306 back and forth, and then move the polyester yarn passing through it back and forth, so that it can be wound at different positions on the polyester yarn winding drum 404, and move back and forth at a uniform speed, so as to prevent the polyester yarn from being wound too much or too little at a certain position on the polyester yarn winding drum 404 during the winding process.

[0030] like Figure 2 As shown, a polyester yarn anti-breakage winding mechanism, the polyester yarn winding component 4 is used to wind the polyester yarn, the limiting column 407 forms an elastic structure with the winding roller 402 through the return spring 406, and the winding roller 402 forms a rotating structure with the third rotating shaft 408, the rotating ball 409 and the support column 410, the limiting baffle 405 and the limiting column 407 cooperate with each other to facilitate the limitation of the polyester yarn winding drum 404, and the limiting column 407 can be pressed inward and contracted so that the polyester yarn winding drum 404 can be removed after the winding is completed, and a rotating ball 409 is provided at the connection between the third rotating shaft 408 and the support column 410 to reduce the friction between the third rotating shaft 408 and the support column 410.

[0031] Working principle: The internal structure of the pressing base 213 is consistent with that of the first U-shaped base 205 and the second U-shaped base 209. First, tighten the fixing bolt 212 and rotate to open the second U-shaped base 209. The polyester thread transmitted from the upstream thread supply mechanism is placed on the pressing base 213 and the first rotating wheel 207 on the inner wall of the first U-shaped base 205 in sequence. Then, the second U-shaped base 209 is rotated to close and fixed with the fixing bolt 212. Then, the polyester thread is passed through the polyester thread guide ring 306 and its end is fixed on the polyester thread winding drum 404.

[0032] When winding, the second servo motor 401 and the first servo motor 302 are started, and the output end of the second servo motor 401 rotates together with the polyester yarn winding drum 404 through the winding roller 402, so that the polyester yarn can be wound on the outer wall of the polyester yarn winding drum 404. At the same time, the output end of the first servo motor 302 drives the ball screw 303 to rotate forward and backward. When the ball screw 303 rotates forward and backward, the ball nut 304 will move back and forth outside it, and then drive the polyester yarn guide ring 306 to move back and forth through the supporting vertical rod 305, so that the polyester yarn can be wound on different positions on the polyester yarn winding drum 404.

[0033] The buffer spring 202 can be positioned at a certain height against the first U-shaped holder 205, and interact with the downward pressing holders 213 on both sides thereof, so that the polyester thread before winding is in a tensioned state. When the polyester thread is suddenly tightened due to uneven supply of the upstream thread, the thread can press the first rotating wheel 207 downward, contracting the buffer spring 202, thereby reducing the height difference between the first rotating wheel 207 and the downward pressing holders 213 on both sides, buffering the thread during release and preventing it from being too tight and breaking.

[0034] When winding is completed, pull out the limit pin 411, move backward to remove the support column 410, and then press inward to retract the limit column 407 into the interior of the winding roller 402, and then slide outward to remove the polyester thread winding drum 404 and the polyester thread wrapped around it.

[0035] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention as claimed.
