Technical Field

[0001] This utility model relates to the field of polyester spinning technology, specifically to a spinning device for pre-oriented polyester yarn. Background Technology

[0002] Polyester pre-oriented yarn is an important intermediate product in synthetic fiber production, characterized by moderate orientation and stable structure, and is widely used in textiles, apparel, and industrial yarns. With the textile industry's increasing demand for high-performance, multi-functional yarns, ply spinning technology has become a key process for optimizing POY performance. By combining multiple monofilaments, the strength, uniformity, and processing performance of the yarn can be significantly improved, meeting the higher requirements of downstream texturing and weaving processes.

[0003] According to CN220642031U, a doubling machine that can improve spinning quality is disclosed. This technology addresses the problem that existing take-up rollers are rotatably connected between two mounting parts, making disassembly and replacement inconvenient after the surface of the take-up roller is fully wound with plied yarn, increasing workload and reducing work efficiency. The proposed solution includes a base; a doubling assembly, with a first fixing plate fixedly connected to the top of the base, and the doubling assembly located on one side of the first fixing plate for combining yarns; a second rotating shaft, with a third fixing plate fixedly connected to the top of the base, and the second rotating shaft rotatably connected within the third fixing plate for placing the take-up roller; a set of positioning components is provided within the second rotating shaft to fix the take-up roller to the surface of the second rotating shaft; reducing workload and effectively improving work efficiency.

[0004] Existing polyester pre-oriented yarn twisting and spinning equipment generally suffers from inconvenient adjustment and poor versatility when fixing rolls of different diameters. Traditional equipment usually uses fixed-size support plates or manual adjustment mechanisms, which makes it cumbersome and time-consuming to change rolls, and it is difficult to ensure the clamping stability of rolls of different specifications, affecting the continuity and efficiency of subsequent twisting and spinning. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a spinning device for pre-oriented polyester yarn. By automatically adjusting the spacing of the support plates, it adapts to different roll diameters, improving versatility. The guide wheel rolling and double-guide design ensure stable translation, avoiding jamming and skew, and achieving efficient and precise roll fixing and unfixing, thus enhancing the adaptability and reliability of the equipment.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a spinning device for pre-oriented polyester yarn, comprising a frame, wherein a supply mechanism is provided on the frame for fixing polyester yarn rolls, and the supply mechanism includes:

[0007] The main component includes several bearing seats fixed inside the frame, a shaft cylinder rotatably mounted on the bearing seats, a circular plate fixed to the upper outer wall of the shaft cylinder, several circumferentially distributed support plates slidably mounted on the upper end of the circular plate, connecting rods pivotally connected to the upper and lower ends of the inner side of the support plates, a guide plate pivotally connected between the two connecting rods, and guide grooves opened at the upper and lower ends of the guide plate, an outer cylinder slidably mounted on the upper end of the shaft cylinder, a first ring seat fixed to the upper and lower ends of the outer wall of the outer cylinder, a first cam rotatably mounted on the outer end of the first ring seat, and the first cam is located in the guide groove;

[0008] The drive assembly is located inside the rack and is used to control the main components.

[0014] Beneficial effects

[0015] This invention provides a spinning apparatus for pre-oriented polyester yarn. Compared with the prior art, it has the following advantages:

[0016] 1. The output end of the electric push rod drives the shaft to move. The shaft, in conjunction with the outer cylinder, drives the first ring seat. The first ring seat, through the first cam and the guide groove, drives the guide plate. The guide plate, through the connecting rod, drives the support plate to move horizontally. At the same time, the distance between the support plate and the shaft is automatically adjusted to fix and release the polyester filament roll. Furthermore, through the automatic adjustment of the support plate distance, it can adapt to polyester filament rolls of different diameters, improving versatility.

[0017] 2. When the support plate moves horizontally, it drives the guide wheel to roll along the circular plate, ensuring the stability of the support plate during the horizontal movement and avoiding jamming; and when the guide plate moves, it drives the second ring seat to move along the outer cylinder through the balance groove and the second cam. At the same time, the second cam also moves along the inside of the balance groove, realizing the cooperation between the second cam and the balance groove to form a dual guiding mechanism, which counteracts the lateral force when the guide plate moves and prevents the structure from tilting.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1 - Figure 4 This utility model provides a technical solution: a spinning device for pre-oriented polyester yarn, including a frame 1, on which a supply mechanism 2 is provided for fixing polyester yarn rolls, the supply mechanism 2 including:

[0025] The main component 21 includes several bearing seats 211 fixed inside the frame 1. A shaft cylinder 212 is rotatably mounted on the bearing seat 211. A circular plate 213 is fixed on the upper outer wall of the shaft cylinder 212. Several circumferentially distributed support plates 214 are slidably mounted on the upper end of the circular plate 213. A connecting rod 215 is pivotally connected to the upper and lower ends of the inner side of the support plate 214. A guide plate 216 is pivotally connected between the two connecting rods 215. A guide groove 217 is opened at both the upper and lower ends of the guide plate 216. An outer cylinder 218 is slidably mounted on the upper end of the shaft cylinder 212. A first ring seat 219 is fixed at both the upper and lower ends of the outer wall of the outer cylinder 218. A first cam 2110 is rotatably mounted on the outer end of the first ring seat 219, and the first cam 2110 is located in the guide groove 217.

[0026] The drive component 22 is located inside the rack 1 and is used to control the main component 21.

[0027] In this embodiment, the first ring seat 219 is driven by the shaft 221 in conjunction with the outer cylinder 218. The first ring seat 219 drives the guide plate 216 through the first cam 2110 in conjunction with the guide groove 217. The guide plate 216 drives the support plate 214 to move through the connecting rod 215. At the same time, the distance between the support plate 214 and the shaft is automatically adjusted to fix and release the polyester filament roll. Furthermore, the automatic adjustment of the distance between the support plates 214 can accommodate polyester filament rolls of different diameters, improving versatility.

[0028] Specifically, the main component 21 also includes two guide wheels 2111 that are rotatably mounted on both sides of the lower end of the support plate 214.

[0029] In this embodiment, when the support plate 214 is translated, the guide wheel 2111 is driven to roll along the circular plate 213 to ensure that the translation process of the support plate 214 is stable and to avoid jamming.

[0030] Specifically, the main body component 21 also includes a balance groove 2112 opened inside the guide plate 216, a second ring seat 2113 slidably installed on the outer wall of the outer cylinder 218, a second cam 2114 rotatably installed on the outer end of the second ring seat 2113, and the second cam 2114 is located in the balance groove 2112.

[0031] In this embodiment, when the guide plate 216 moves, the second ring seat 2113 moves along the outer cylinder 218 through the balance groove 2112 and the second cam 2114. At the same time, the second cam 2114 also moves along the inside of the balance groove 2112, so that the second cam 2114 and the balance groove 2112 cooperate to form a dual guiding mechanism, which counteracts the lateral force when the guide plate 216 moves and prevents the structure from tilting.

[0032] Specifically, the drive assembly 22 includes a shaft 221 that is slidably mounted inside the shaft seat 211, and the upper end of the shaft 221 is fixed to the upper end of the outer cylinder 218. Several electric push rods 222 are installed inside the frame 1 and are used to drive the shaft 221 to rotate.

[0033] In this embodiment, the shaft 221 is moved by the output end of the electric push rod 222.

[0034] Specifically, the drive assembly 22 also includes a driven pulley 223 fixed to the lower outer wall of the shaft seat 211. Several motors 224 are installed inside the frame 1. A drive pulley 225 is fixed to the output end of the motor 224. A belt 226 is installed between the drive pulley 225 and the driven pulley 223.

[0035] In this embodiment, the output end of the motor 224 drives the active pulley 225 to rotate in conjunction with the belt 226 to drive the driven pulley 223 to rotate. The driven pulley 223 drives the drum fixed on the main body component 21 to take in and unload the polyester filament.

[0036] Specifically, the supply mechanism 2 also includes several uprights 23 fixed on the frame 1, with guide wheels 24 rotatably mounted on the upper end of the uprights 23, and a bundling device 25 fixed at one end of the frame 1.

[0037] In this embodiment, the guide wheel 24 guides the path of the single filament, reducing friction and fuzz generation, and ensuring that the polyester filament has uniform tension before entering the bundling device 25 for twisting.

[0038] The working principle and usage process of this utility model are as follows: First, the output end of the electric push rod 222 drives the shaft 221 to move. The shaft 221, in conjunction with the outer cylinder 218, drives the first ring seat 219. The first ring seat 219, through the first cam 2110 and in conjunction with the guide groove 217, drives the guide plate 216. The guide plate 216, through the connecting rod 215, drives the support plate 214 to move horizontally. At the same time, the distance between the support plate 214 and the shaft is automatically adjusted to fix and release the polyester filament roll. Furthermore, through the automatic adjustment of the distance between the support plates 214, it can adapt to polyester filament rolls of different diameters, improving versatility.

[0039] Meanwhile, when the support plate 214 moves, it drives the guide wheel 2111 to roll along the circular plate 213, ensuring the stability of the support plate 214 during the translation process and avoiding jamming; and when the guide plate 216 moves, it drives the second ring seat 2113 to move along the outer cylinder 218 through the balance groove 2112 in cooperation with the second cam 2114. At the same time, the second cam 2114 also moves along the inside of the balance groove 2112, realizing the cooperation between the second cam 2114 and the balance groove 2112 to form a dual guiding mechanism, which counteracts the lateral force when the guide plate 216 moves and prevents the structure from tilting.

[0040] Then, the output end of the motor 224 drives the active pulley 225 to rotate in conjunction with the belt 226 to drive the driven pulley 223 to rotate. The driven pulley 223 drives the drum fixed on the main component 21 to take in and unwind the polyester filaments. In addition, the guide wheel 24 guides the path of the single filaments to reduce friction and fuzz generation, ensuring that the tension of the polyester filaments is uniform before entering the bundling device 25 for plying.
