Description

Technical Field

[0001] This utility model relates to the technical field of chemical fiber production equipment, specifically to a multi-specification flexible traction component for pre-oriented polyester POY yarn. Background Technology

[0002] Polyester POY pre-oriented yarn, also known as high-speed spinning, is an incompletely stretched fiber made from polyester (PET) through melt spinning. Polyester POY pre-oriented yarn is an important intermediate raw material for the production of various polyester filament products. Through further stretching, texturing and other post-processing, it can be made into polyester yarn with different properties, such as drawn textured yarn (DTY) and fully drawn yarn (FDY), which are used to weave various clothing fabrics, home textiles and other products.

[0003] Referring to the patent document: Patent Publication No. CN215159881U, Patent Publication Date 2021-12-14, a flexible winding device based on ultra-bright polyester pre-oriented yarn is disclosed. The device includes a machine body, which, from left to right, has a winding area, a passing area, and a releasing area. A front box and a rear box are located on the front and rear sides of the passing area. A partition is fixedly connected to the middle of the interior of both the front and rear boxes. A first tension member is located at the bottom of the partition in both the front and rear boxes, and a second tension member is located on the upper left side of the interior cavity of both the front and rear boxes. This flexible winding device based on ultra-bright polyester pre-oriented yarn utilizes a driving wheel to drive a driven wheel, thereby initiating the winding of the first yarn core. During winding, the elastic components of the first and second tension members buffer the oriented yarn, preventing uneven releasing speeds during the releasing process that could lead to tangled polyester oriented yarns, thus improving production speed and ensuring smooth operation.

[0004] Based on the search of patent numbers and the shortcomings of existing technologies, the following was found:

[0005] In the production of pre-oriented polyester POY yarn in the prior art, the traction assembly is a key component to ensure production continuity and guide the yarn. However, in actual use, the guide traction wheels in the traction assembly are mostly fixed, and the position of the traction wheels cannot be adjusted according to the production path required by the product to transport it to different processing environments. For example, if traditional equipment is connected to texturing or stretching equipment for further processing, or if other processing is required after winding, the position of the traction rollers cannot be flexibly switched so that the yarn can be guided in different directions for different processing steps under the same traction mechanism.

[0006] Therefore, this utility model provides a multi-specification flexible traction assembly for pre-oriented polyester POY yarn. Utility Model Content

[0007] To address the problem that existing traction components for yarn are mostly fixed and cannot change the movement path of the yarn, thus only enabling unidirectional yarn transport, the purpose of this invention is to provide a multi-specification flexible traction component for polyester POY pre-oriented yarn.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a multi-specification flexible traction assembly for pre-oriented polyester POY yarn, comprising a housing, wherein a traction mechanism is provided on one side of the housing for guiding and traction of the yarn, the traction mechanism comprising:

[0009] The guide assembly includes a mounting shell disposed on one side of the outer casing. Two symmetrically distributed drive gears are rotatably mounted on one side of the mounting shell. A drive link is fixedly mounted on the middle of one side of each of the two drive gears, and the two drive links are mirror-distributed. A drive assembly is provided on one side of one of the drive gears. Limit gears are rotatably mounted on one side of each end of the two drive links, and the two limit gears are meshed with the drive gears. Deflection links are rotatably mounted on the other side of each end of the two drive links. One side of each deflection link is fixedly mounted on the middle of one side of the limit gear. A moving block is rotatably mounted on one end of each deflection link. A moving traction roller is fixedly mounted on one side of each moving block. An initial traction roller is mounted on the upper part of the outer casing, and two symmetrically distributed guide traction rollers are mounted on the lower part of the outer casing.

[0010] The cleaning mechanism is used to remove burrs from the outer surface of the produced yarn.

[0011] Preferably, the cleaning mechanism includes a servo motor fixedly installed on one side of the upper part of the outer casing, and two symmetrically distributed cleaning rollers are rotatably installed on the upper part of the outer casing, one end of which is fixedly installed on the drive end of the servo motor.

[0012] Preferably, the drive assembly includes a drive motor fixed to one side of the upper part of the mounting housing, and one of the drive gears is fixedly mounted on the drive end of the drive motor at the middle of one side.

[0013] Preferably, the two drive gears are connected by a synchronous belt drive, and the two cleaning rollers are connected by a transmission belt drive.

[0014] Preferably, two symmetrically distributed moving slots are provided on one side of the outer shell, and two moving blocks are slidably engaged inside the moving slots.

[0015] Preferably, two symmetrically distributed limiting grooves are provided on the other side of the outer shell, and one end of the two movable traction rollers is slidably locked in the middle of the limiting grooves.

[0016] Preferably, the mounting shell has symmetrically distributed annular grooves in the middle of one side, and the middle of one end of each of the two limiting gears is slidably engaged in the middle of the annular groove.

[0017] Beneficial effects

[0018] This invention provides a multi-specification flexible traction assembly for pre-oriented polyester POY yarn. Compared with the prior art, it has the following advantages:

[0019] 1. This application uses a drive motor to drive a drive gear to rotate, and a synchronous belt to make the two drive gears run synchronously. The drive linkage deflects accordingly, causing the limit gear to rotate around the outside of the drive gear. This causes the deflection linkage to push the moving block to move in the moving groove, realizing the interchange of the positions of the upper and lower moving traction rollers. This allows for a rapid change of the thread path. Under the limiting of this guide component, the thread can be conveyed to different processing equipment, improving the equipment's versatility and production efficiency.

[0020] 2. This application uses a servo motor to drive the cleaning roller to rotate in the opposite direction to the direction of the yarn movement, and the two cleaning rollers operate synchronously through a transmission belt. No matter how the yarn path changes, there is always one cleaning roller in contact with the yarn. The nylon bristles on its surface comb and scrape the outer surface of the yarn, remove burrs in time, ensure the yarn surface is smooth, and provide high-quality raw materials for subsequent processing.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0027] Please see Figure 1-4 This utility model provides a technical solution: a multi-specification flexible traction assembly for pre-oriented polyester POY yarn, including a housing 1, with a traction mechanism 2 on one side of the housing 1 for guiding and traction of the yarn. The traction mechanism 2 includes:

[0028] The guide assembly 21 includes a mounting shell 211 disposed on one side of the outer casing 1. Two symmetrically distributed drive gears 213 are rotatably mounted on one side of the mounting shell 211. Drive connecting rods 215 are fixedly mounted on the middle of one side of each of the two drive gears 213, and the two drive connecting rods 215 are mirror-distributed, such that when the two drive gears 213 rotate synchronously, the deflection directions of the two drive connecting rods 215 are different, thus causing the movement directions of the two moving blocks 216 to be different. The drive connecting rods 215 are made of high-strength aluminum alloy with a rectangular hollow cross-section, reducing weight while ensuring torsional stiffness. One of the drive gears 213... A drive assembly is provided on the side. Limiting gears 214 are rotatably mounted on one side of the ends of the two drive links 215. The two limiting gears 214 are meshed with the drive gears 213. Deflection links 2151 are rotatably mounted on the other side of the ends of the two drive links 215. One side of the two deflection links 2151 is fixedly mounted on the middle of one side of the limiting gears 214. A moving block 216 is rotatably mounted on one end of the two deflection links 2151. A moving traction roller 217 is fixedly mounted on one side of the two moving blocks 216. An initial traction roller 218 is installed on the upper part of the outer shell 1. Two symmetrically distributed guide traction rollers 219 are installed on the lower part of the outer shell 1.

[0029] Cleaning mechanism 22 is used to remove burrs from the outer surface of the produced yarn.

[0030] The cleaning mechanism 22 includes a servo motor 221 fixedly installed on one side of the upper part of the outer casing 1. The servo motor 221 is an AC permanent magnet synchronous servo motor. The servo motor 221 is connected to the circuit through a dedicated servo driver. The rotation speed of the servo motor 221 is controlled by connecting to the control system. Two symmetrically distributed cleaning rollers 222 are rotatably installed on the upper part of the outer casing 1. The surface of the cleaning rollers 222 is wrapped with high-toughness nylon bristles. One end of one of the cleaning rollers 222 is fixedly installed on the drive end of the servo motor 221.

[0031] The drive assembly includes a drive motor 212 fixed on one side of the upper part of the mounting housing 211. The drive motor 212 is a servo planetary geared motor, which is connected to the circuit through a dedicated servo driver. At the same time, the driver is connected to the control system of the yarn production equipment through a communication interface. The control system controls the start and stop of the drive motor 212, thereby adjusting the yarn conveying path. One of the drive gears 213 is fixedly installed on the drive end of the drive motor 212 at the middle of one side.

[0032] Two drive gears 213 are connected by a synchronous belt drive. The synchronous belt is a polyurethane synchronous belt drive with trapezoidal teeth, which has the characteristics of high transmission efficiency and low noise. Two cleaning rollers 222 are connected by a transmission belt drive.

[0033] Two symmetrically distributed moving slots 2161 are provided on one side of the outer shell 1. Two moving blocks 216 are slidably locked inside the moving slots 2161. The cross-section of the moving slots 2161 is T-shaped to ensure the smoothness and stability of the movement of the moving blocks 216.

[0034] Two symmetrically distributed limiting grooves 2171 are provided on the other side of the outer shell 1. One end of the two movable traction rollers 217 is slidably locked in the middle of the limiting grooves 2171. The limiting grooves 2171 play a radial limiting role on the movable traction rollers 217, ensuring that the movable traction rollers 217 can move stably.

[0035] A symmetrically distributed annular groove 2141 is provided on the middle of one side of the mounting housing 211. The middle of one end of each of the two limiting gears 214 is slidably locked in the middle of the annular groove 2141. The annular groove 2141 provides guidance and support for the rotation of the limiting gears 214.

[0036] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0037] During operation, the path of its yarn through the traction roller can be from... Figure 3 As can be seen, the wire first enters the interior of the outer casing 1 through the initial traction roller 218, passes through the middle of the upper moving traction roller 217, and then passes through the middle of the lower moving traction roller 217. The upper moving traction roller 217 and the lower moving traction roller 217 are always misaligned. After the wire passes through the lower moving traction roller 217, it reaches the lower part of the guide traction roller 219 on the side away from the lower moving traction roller 217, thereby conducting the wire out for collection or into other processing equipment.

[0038] When it is necessary to adjust the path through which the thread passes, the drive motor 212 can be started to drive the drive gear 213 to rotate. Under the transmission of the synchronous belt, the two drive gears 213 rotate synchronously, which causes the two drive linkages 215 to deflect, causing the meshing limit gear 214 to rotate around the outside of the drive gear 213, that is, causing the deflection linkage 2151 to deflect. The initial directions of the two drive linkages 215 are mirror images. When rotating, one deflects upward and the other deflects downward. Under the limitation of the moving block 216 by the moving groove 2161, the two moving blocks 216 can be moved relative to each other by the movement and deflection of the deflection linkage 2151. This causes the positions of the upper and lower moving traction rollers 217 to be exchanged relative to each other. As a result, the lower moving traction roller 217 is farthest from the guide traction roller 219 on the side that delivers the thread, thereby changing the path of the thread.

[0039] While guiding and conveying the yarn, the two cleaning rollers 222 rotate synchronously under the drive of the servo motor 221 and the transmission belt, and the rotation direction is opposite to the direction in which the yarn enters, thereby removing the burrs generated on the outer surface of the yarn. The two cleaning rollers 222 are set so that no matter which side the yarn path changes to, one cleaning roller 222 is in contact with the yarn, thereby removing the burrs generated on its outer surface.
