Description

Technical Field

[0001] This utility model relates to the field of yarn guiding technology for winding machines, specifically to a yarn guiding device for winding machines. Background Technology

[0002] Winding machines are specialized equipment in the textile industry. As the final step in spinning and the first step in weaving, winding plays a crucial "bridge" role, thus holding an important position in the textile field. When the yarn moves on the winding machine, it is guided by a yarn guide assembly.

[0003] During the movement of the yarn, it needs to repeatedly rub against the guiding device. At the same time, when the yarn is subjected to excessive tension, it is easy for the yarn to break frequently, reducing the quality of the yarn. When the yarn breaks, the thread end is easy to fall off the device and fall to the ground, which can lead to a long time to find the thread end during subsequent yarn pulling. Based on this, this solution provides a yarn guiding device for a winding machine to solve the above-mentioned problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, a yarn guiding device for a winding machine is provided. This technical solution solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A yarn guiding device for a winding machine includes a base plate. A first guide assembly, a second guide assembly, and a tensioning assembly are fixedly installed on the base plate. The first guide assembly and the second guide assembly have identical overall structures and are symmetrically arranged on both sides of the tensioning assembly. The first guide assembly includes a base fixedly installed on the base plate. A lifting frame is slidably connected to the base, and a drive unit for driving the lifting frame is provided on the base. A mounting seat one is fixedly installed at the top of the lifting frame. A pressure roller is rotatably installed on the mounting seat one. A mounting seat two is fixedly installed at the top of the base on the lower side of the pressure roller. A yarn groove wheel is rotatably installed inside the mounting seat two.

[0007] Preferably, the drive unit includes an electric push rod fixedly mounted on the base, the output shaft of the electric push rod is fixedly connected to a push plate, a protrusion is provided on the lower side of the push plate, one end of the protrusion is fixedly connected to the lifting frame, and a spring is fixedly connected between the lifting frame and the inner wall of the base.

[0008] Preferably, a sliding groove 1 is provided through the inner walls on both sides of the base for sliding with the lifting frame, and a sliding groove 2 is provided through the right end of the base for sliding with the protruding plate.

[0009] Preferably, the tensioning assembly includes a frame fixedly mounted on a base plate, with guide roller 1 and guide roller 2 rotatably mounted on both sides of the front end of the frame, and a rotating shaft rotatably mounted at the middle of the front end of the frame; a rotating frame is fixedly mounted at the front end of the rotating shaft, with tension line wheel 1 and tension line wheel 2 rotatably mounted at both ends of the rotating frame, a fixed plate fixedly connected to the rear end of the rotating frame, and a torsion spring sleeved on the rear end surface of the rotating frame, with both ends of the torsion spring fixedly connected to the fixed plate and the frame, respectively.

[0010] Preferably, the frame is provided with guide groove 1 and guide groove 2 for limiting the rotation of the rotating frame. Guide groove 1 and guide groove 2 are coaxially arranged with the central axis of the rotating shaft, and guide post 1 and guide post 2 are fixedly connected to the rear ends of the rotating frame respectively. Guide post 1 and guide post 2 are slidably connected to guide groove 1 and guide groove 2 respectively.

[0011] Preferably, a yarn breakage detector is fixedly installed on the rotating frame between tension sheave one and tension sheave two.

[0012] Compared with the prior art, the present invention proposes a yarn guiding device for a winding machine, which has the following beneficial effects:

[0013] 1. This utility model includes a first guide component and a second guide component. The overall structure of the first guide component and the second guide component are exactly the same, and their functions are also the same. Taking the first guide component as an example: when the electric push rod is not activated, the spring force and the fixed connection between the spring and the lifting frame allow the pressure roller to press gently against the lower yarn groove wheel. This pressure can both clamp the yarn to prevent it from falling off and prevent excessive wear or breakage of the yarn due to excessive pressure. When a yarn breakage is detected, the electric push rod is quickly activated, pushing the push plate, compressing the spring, and driving the lifting frame and pressure roller to press down as a whole, thereby quickly pressing down the broken yarn. This makes it convenient for operators to quickly find and deal with the yarn end, effectively avoiding the cumbersome and time-consuming situation when pulling the yarn.

[0014] 2. This utility model includes a tensioning assembly, in which the yarn sequentially winds around guide roller one, tension wheel one, tension wheel two, and guide roller two, forming an "S"-shaped winding path. When the yarn tension increases, tension wheels one and two are driven by the yarn tension, causing the rotating frame to rotate around the rotating axis, and the torsion spring is twisted to generate a reverse elastic restoring force. When the yarn tension decreases, the torsion spring resets and drives the rotating frame to rotate in the opposite direction, and the tension wheels actively engage with the loose yarn. This effectively improves the elastic adjustment mechanism formed by the torsion spring and the rotating frame, achieving real-time buffering of yarn tension fluctuations, maintaining constant tension, and preventing the yarn from breaking due to excessive tension or wrinkling due to insufficient tension. Furthermore, when the rotating frame rotates, the maximum rotation angle of the rotating frame is limited by the sliding of guide posts one and two along coaxially arranged guide grooves one and two. Simultaneously, when the yarn breaks, a yarn breakage detector located between tension wheels one and two triggers a signal to achieve machine stop protection. Attached Figure Description

[0024] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0025] Reference Figure 1 As shown, a yarn guiding device for a winding machine includes a base plate 1, on which a first guiding component 2, a second guiding component 3 and a tensioning component 4 are fixedly installed. The first guiding component 2 and the second guiding component 3 have the same overall structure and are symmetrically arranged on both sides of the tensioning component 4.

[0026] Furthermore, the symmetrical design of the first guide component 2 and the second guide component 3 ensures that the yarn is subjected to uniform force during the guiding process, effectively reducing uneven wear and vibration, thereby improving the stability of the yarn during movement.

[0027] Reference Figure 2 As shown, specifically in this embodiment, the first guide component 2 includes a base 201 fixedly installed on the base plate 1, a lifting frame 202 slidably connected to the base 201, and a drive unit for driving the lifting frame 202 is provided on the base 201. A mounting seat 1 207 is fixedly installed at the top of the lifting frame 202, a pressure roller 208 is rotatably installed on the mounting seat 1 207, and a mounting seat 209 fixedly installed at the top of the base 201 is provided on the lower side of the pressure roller 208. A grooved wheel 2010 is rotatably installed inside the mounting seat 209.

[0028] Furthermore, the yarn is guided by the pressure roller 208 and the grooved roller 2010 to ensure smooth passage of the yarn and reduce friction and wear.

[0029] Reference Figure 2-3 As shown, specifically in this embodiment, the drive unit includes an electric push rod 2011 fixedly installed on the base 201. The output shaft of the electric push rod 2011 is fixedly connected to a push plate 2012. A protruding plate 203 is provided on the lower side of the push plate 2012. One end of the protruding plate 203 is fixedly connected to the lifting frame 202. A spring 206 is fixedly connected between the lifting frame 202 and the inner wall of the base 201.

[0030] Furthermore: When the electric push rod 2011 is not activated, the elastic force of the spring 206, through its connection with the lifting frame 202, causes the pressure roller 208 to press gently against the lower yarn groove roller 2010. This pressure is sufficient to clamp the yarn and prevent it from slipping off, without causing excessive wear or breakage due to excessive pressure. When a yarn breakage is detected, the electric push rod 2011 quickly activates, pushing the push plate 2012, compressing the spring 206, and causing the lifting frame 202 and pressure roller 208 to press down as a whole, thereby quickly pressing down the broken yarn. This facilitates the operator in quickly locating and handling the yarn end, effectively avoiding the cumbersome and time-consuming process of pulling the yarn.

[0031] Reference Figure 2-3 As shown, specifically in this embodiment, both sides of the inner wall of the base 201 are provided with a sliding groove 204 for sliding with the lifting frame 202, and the right end of the base 201 is provided with a sliding groove 205 for sliding with the protrusion 203.

[0032] Furthermore: the lifting frame 202 slides in the first slide groove 204, and the protruding plate 203 slides in the second slide groove 205, guiding the lifting frame 202 to move in a straight line. The design of the slide grooves ensures accurate movement trajectory, prevents deviation or jamming, and can improve structural rigidity and stability, and reduce wear and maintenance requirements.

[0033] Reference Figure 4-5 As shown, specifically in this embodiment, the tensioning assembly 4 includes a frame 401 fixedly mounted on the base plate 1. Guide roller 1 402 and guide roller 2 403 are rotatably mounted on both sides of the front end of the frame 401, and a rotating shaft 404 is rotatably mounted on the middle of the front end of the frame 401. A rotating frame 405 is fixedly mounted on the front end of the rotating shaft 404. Tension line wheel 1 407 and tension line wheel 2 408 are rotatably mounted on both ends of the rotating frame 405, and a fixing plate 4013 is fixedly connected to the rear end of the rotating frame 405. A torsion spring 4014 is sleeved on the rear end surface of the rotating frame 405, and both ends of the torsion spring 4014 are fixedly connected to the fixing plate 4013 and the frame 401, respectively.

[0034] Furthermore, in the tensioning assembly 4, the yarn sequentially winds around guide roller 1 402, tension wheel 1 407, tension wheel 2 408, and guide roller 2 403, forming an "S"-shaped winding path. When the yarn tension increases, tension wheels 1 407 and 2 408 are driven by the yarn tension, causing the rotating frame 405 to rotate around the rotating shaft 404, and the torsion spring 4014 is twisted to generate a reverse elastic restoring force. When the yarn tension decreases, the torsion spring 4014 resets and drives the rotating frame 405 to rotate in the opposite direction, and the tension wheels actively engage with the loose yarn. The torsion spring 4014 and the rotating frame 405 effectively form an elastic adjustment mechanism, achieving real-time buffering of yarn tension fluctuations, maintaining constant tension, and preventing the yarn from breaking due to excessive tension or wrinkling due to insufficient tension.

[0035] Reference Figure 4-5 As shown, specifically in this embodiment, the frame 401 is provided with a guide groove 409 and a guide groove 4010 for limiting the rotation of the rotating frame 405. The guide groove 409 and the guide groove 4010 are coaxially arranged with the central axis of the rotating shaft 404, and the rear ends of the rotating frame 405 are respectively fixedly connected with guide posts 4011 and 4012. The guide posts 4011 and 4012 are slidably connected to the guide groove 409 and the guide groove 4010 respectively.

[0036] Furthermore, guide post 4011 and guide post 4012 slide within guide groove 409 and guide groove 4010 respectively, limiting the rotation angle of rotating frame 405, ensuring that tension sheave 407 and tension sheave 408 move within a safe range, and preventing excessive rotation from damaging the components.

[0037] Reference Figure 4-5 As shown, specifically in this embodiment, a yarn breakage detector 406 is fixedly installed on the rotating frame 405 between tension sheave 1 407 and tension sheave 2 408.

[0038] Furthermore, the yarn breakage detector 406 monitors the yarn status in real time and sends a signal when a yarn breakage is detected, triggering a shutdown or alarm. This enables timely detection of yarn breakage issues, reduces production interruptions and material waste, and improves automation and production efficiency.

[0039] The working principle of this utility model is as follows: the yarn passes through the first guide component 2, the tensioning component 4 and the second guide component 3 in sequence. The overall structure of the first guide component 2 and the second guide component 3 are exactly the same, and their functions are also the same. Taking the first guide component 2 as an example: when the electric push rod 2011 is not started, the elastic force of the spring 206 causes the pressure roller 208 to press against the lower grooved wheel 2010 with a gentle pressure through the connection with the lifting frame 202. This pressure can both clamp the yarn so that it does not fall off, and will not cause excessive wear or breakage of the yarn due to excessive pressure.

[0040] In tensioning assembly 4, the yarn sequentially winds around guide roller 1 402, tension wheel 1 407, tension wheel 2 408, and guide roller 2 403, forming an "S"-shaped winding path. When the yarn tension increases, tension wheel 1 407 and tension wheel 2 408 are driven by the yarn tension, causing the rotating frame 405 to rotate around the rotating shaft 404, and the torsion spring 4014 is twisted to generate a reverse elastic restoring force. When the yarn tension decreases, the torsion spring 4014 resets and drives the rotating frame 405 to rotate in the opposite direction, and the tension wheel actively engages with the loose yarn. The torsion spring 4014 and the rotating frame 405 effectively form an elastic adjustment mechanism to achieve real-time buffering of yarn tension fluctuations, maintain constant tension, and prevent the yarn from breaking due to excessive tension or wrinkling due to insufficient tension.

[0041] A yarn breakage detector 406 is fixedly installed on the rotating frame 405 between tension roller 1 407 and tension roller 2 408. The yarn breakage detector 406 monitors the yarn status in real time and sends a signal when a yarn breakage is detected. The electric push rod 2011 of the first guide assembly 2 and the corresponding components of the second guide assembly 3 are quickly activated, pushing the push plate 2012, compressing the spring 206, and driving the lifting frame 202 and the pressure roller 208 to press down as a whole, thereby quickly pressing down the broken yarn. This makes it easier for operators to quickly find and deal with the yarn end, effectively avoiding the cumbersome and time-consuming situation when pulling the yarn.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
