Abstract
Description
Technical Field
[0001] This utility model relates to the field of textile machinery technology, specifically to a DTY textured yarn winding device. Background Technology
[0002] DTY, or stretch textured yarn, is a core material in the chemical fiber textile industry. It uses polyester chips (PET) as raw material and processes ordinary filaments (such as POY pre-oriented yarn) into crimped fibers with elasticity, fluffiness, and soft hand feel through a "high-speed spinning → stretching → texturing" process. Essentially, it gives fibers textile properties similar to natural yarn through physical deformation and is widely used in clothing, home textiles, industrial fabrics and other fields.
[0003] Referring to the patent document: Patent Publication No. CN220596627U, Patent Publication Date 2024-03-15, it discloses a DTY textured yarn winding device, including a base, a support frame fixedly connected to the top of the base, a limiting device rotatably connected to the end of the support frame, the limiting devices being symmetrically arranged, a winding drum being provided in the gap between the limiting devices, the limiting devices engaging with the winding drum, and a driving device fixedly connected to the top of the base, the driving device being connected to one of the limiting devices. This relates to the field of textile machinery technology. This DTY textured yarn winding device achieves the goal of having a support frame set at the top of the base for installing the limiting devices, and the limiting devices being symmetrically arranged. By placing the winding drum in the gap between the limiting devices and engaging it with the limiting devices, the winding drum can be installed, thereby winding the yarn. This facilitates installation and disassembly by workers and meets the usage requirements.
[0004] Based on the search of patent numbers and the shortcomings of existing technologies, the following was found:
[0005] Traditionally, when twisting DTY textured yarn, a single-station winding device is used to wind it. After the winding roller finishes winding, the machine needs to be stopped, the winding roller on the drive shaft needs to be removed, and a new winding roller needs to be installed on top. The winding roller is then fixed to the drive shaft by a fixing assembly to continue winding. This process is cumbersome and time-consuming, requiring a lot of time and multiple operators to replace the winding rollers, which increases production costs.
[0006] Therefore, this utility model provides a DTY elastic yarn winding device. Utility Model Content
[0007] To address the problem that existing collection devices mostly use single-station winding collection, resulting in long replacement times for winding shafts and affecting production efficiency, the purpose of this utility model is to provide a DTY elastic yarn winding device.
[0008] To achieve the above objectives, this utility model provides the following technical solution: a DTY (Dystyrene) yarn winding device, comprising a fixed frame, wherein two fixed frames are symmetrically distributed, and a winding mechanism is provided in the middle of the two fixed frames for winding and collecting DTY yarn. The winding mechanism includes:
[0009] The feeding assembly includes two rotating plates rotatably mounted in the middle of a fixed frame.

Two sets of driving rollers are installed on the opposite sides of the two rotating plates, and a winding roller is sleeved on the outer side of the driving rollers.
[0010] The cutting assembly, located on one side of the rotating plate, is used for cutting the elastic DTY wire.
[0011] Preferably, the cutting assembly includes two rotating shafts rotatably mounted on one side of the rotating plate, with cutting blades for mutual cooperation fixedly mounted on the outer side of each of the two rotating shafts, and gears fixedly mounted on one end of each of the two rotating shafts. The two gears are meshed with each other, and one of the rotating shafts is connected to the drive disc via a transmission belt.
[0012] Preferably, the feeding assembly further includes two fixed frames fixedly installed in the middle of the rotating plate. A set of springs is fixedly installed at the opposite ends of the two fixed frames. A mounting frame is provided on one side of each of the two fixed frames. One end of each of the two mounting frames is fixedly installed on one side of the spring. A limit roller is rotatably installed on one side of each of the two fixed frames. A top block is fixedly installed at both ends of each of the two mounting frames. Two symmetrically distributed electric push rods are fixedly installed on the opposite sides of the two rotating plates.

[0015] Preferably, the drive assembly includes a drive motor fixedly mounted on one side of the fixed frame, and the drive disk is fixedly mounted on the drive end of the drive motor at the middle of one side.
[0016] Beneficial effects
[0017] This invention provides a DTY (Dystyrene) elastic yarn winding device. Compared with the prior art, it has the following advantages:
[0018] Beneficial effects:
[0019] 1. In this application, when the winding roller on one side is completed, the drive motor drives the active disk to rotate, so that the eccentrically set drive block cooperates with the drive groove of the driven disk, driving the driven disk to rotate 180°, realizing the position exchange of the old and new winding rollers. At the same time, the electric push rod drives the limit roller to support the limit roller when changing the winding roller, avoiding the spring reset from affecting the change speed. This allows the equipment to complete the winding roller change without stopping the machine, significantly shortening the change time.
[0020] 2. This application uses a drive motor to synchronously drive the active disc and the transmission belt, which in turn drives the alloy steel cutting blades on the two rotating shafts to rotate in opposite directions. When the winding is completed, the cutting blades instantly contact and cut the spring-loaded wire. At the same time, the limiting roller maintains the tension on the spring-loaded wire under the action of the spring, preventing the wire ends from loosening after cutting, thus facilitating the subsequent sorting and collection work of the staff.

[0029] 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.
[0030] Please see Figure 1-7 This utility model provides a technical solution: a DTY (Dystyrene) yarn winding device, including a fixed frame 1, two symmetrically distributed fixed frames 1, and a winding mechanism 2 located in the middle of the two fixed frames 1 for winding and collecting DTY yarn. The winding mechanism 2 includes:
[0031] The feeding assembly 21 includes two rotating plates 211 rotatably mounted in the middle of the fixed frame 1. The rotating plates 211 are made of high-strength aluminum alloy and are rotatably connected to the fixed frame 1 through high-precision bearings to ensure smooth and stable rotation. A driven plate 216 is rotatably mounted on one side of one of the fixed frames 1, and one side of the rotating plate 211 is fixedly mounted on one side of the driven plate 216. A driving plate 213 is provided on one side of the driven plate 216, and a drive block 215 is fixedly mounted on one side of the driving plate 213. Two drive blocks 215 are provided in the middle of the driven plate 216 to cooperate with the drive block 215. The drive groove 2151 has a limit block 214 fixedly installed in the middle of one side of the drive disk 213. Two limit grooves 2141 are opened on the outer side of the driven disk 216 to cooperate with the limit block 214. A drive assembly is provided on one side of the drive disk 213. Two sets of drive rollers 219 are installed on the opposite sides of the two rotating plates 211. The drive rollers 219 are used to install and fix the winding rollers 2191. The drive rollers 219 are driven by a conventional servo motor to rotate, thereby driving the winding rollers 2191 to rotate, thus realizing the winding of the elastic DTY yarn. The winding rollers 2191 are sleeved on the outer side of the drive rollers 219.
[0032] The cutting assembly 22 is located on one side of the rotating plate 211 and is used for cutting the elastic wire DTY.
[0033] The cutting assembly 22 includes two rotating shafts 221 rotatably mounted on one side of the rotating plate 211. Cutting blades 222 that cooperate with each other are fixedly mounted on the outer side of the two rotating shafts 221. The cutting blades 222 are made of sharp alloy steel blades and have good cutting performance and durability. Gears 223 are fixedly mounted on one end of the two rotating shafts 221. The two gears 223 are meshed with each other. One of the rotating shafts 221 is connected to the drive disc 213 through a transmission belt.
[0034] The feeding assembly 21 also includes two fixed frames 217 fixedly installed in the middle of the rotating plate 211. A set of springs 2172 is fixedly installed at the opposite ends of each of the two fixed frames 217. A mounting frame 218 is provided on one side of each of the two fixed frames 217. One end of each spring 2172 is fixedly installed on one side of each of the two mounting frames 218. A limit roller 2181 is rotatably installed on one side of each of the two fixed frames 217. A top block 2182 is fixedly installed at both ends of each of the two mounting frames 218. Two symmetrically distributed electric push rods 2183 are fixedly installed on the opposite sides of each of the two rotating plates 211. The electric push rods 2183 adopt… The miniature electric push rod DR-055 is used. The electric push rod 2183 is connected to the control system of the texturing equipment via PLC. When one side of the winding roller 2191 completes winding, the main control system of the texturing equipment detects the signal and sends a command to the PLC. The PLC controls the electric push rod 2183 to start, so that the support block 2184 at its drive end extends and contacts the top block 2182, limiting the limit roller 2181, which facilitates the disassembly and replacement of the winding roller 2191 by the staff. The drive ends of both electric push rods 2183 are fixedly installed with support blocks 2184 that cooperate with the top block 2182.
[0035] Each of the two fixed frames 217 has a set of telescopic sleeves 2171 fixedly installed at opposite ends, and one end of each set of telescopic sleeves 2171 is fixedly installed in the middle of one side of the mounting frame 218.
[0036] Two symmetrically distributed grooves are provided in the middle of each of the two rotating plates 211. Multiple support blocks 2184 are slidably locked inside the grooves, and multiple top blocks 2182 are slidably locked in the middle of the grooves. The grooves can limit the support blocks 2184 and top blocks 2182, and at the same time ensure that the support blocks 2184 can stably limit and fix their top blocks 2182.
[0037] The drive assembly includes a drive motor 212 fixedly mounted on one side of the mounting frame 1. This drive motor 212 is a Delta ECMA series servo motor, model ECMA-C20807RS. The drive motor 212 is connected to the control system of the texturing equipment via a dedicated servo driver. During actual operation, the main control system of the texturing equipment monitors the production progress and winding status of the DTY texturing yarn in real time. When the winding roller 2191 needs to be replaced, the main control system sends a start command to the servo driver, which then controls the drive motor 212 to drive the active winding roller at a set speed. As the disc 213 rotates, the drive motor 212 works in conjunction with the transmission belt, gear 223, and other components in the winding device to drive the rotating shaft 221 to rotate for cutting and to drive the driven disc 216 to rotate to complete the station switching. The entire process is closely coordinated with the production rhythm of the texturing equipment to ensure seamless connection between texturing yarn production and winding. The middle of one side of the drive disc 213 is fixedly installed at the drive end of the drive motor 212. Driven by the drive motor 212, the drive disc 213 can rotate, and at the same time, the rotating shaft 221 can rotate through the transmission belt.
[0038] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
[0039] During operation, the fixed frame 1 can be fixedly installed on the texturing wire equipment with bolts. The DTY produced after texturing is driven by the drive roller 219 to rotate the winding roller 2191, so that it is wound onto the winding roller 2191. The fixed frame 1 has two winding rollers 2191 in the middle, so that it is in a double working position. As the DTY is wound, the DTY texturing wire on the winding roller 2191 can gradually become thicker. At the same time, the limiting roller 2181 can contact the texturing wire wound on the outermost layer of the winding roller 2191 under the action of the spring 2172 and rotate with it, so as to limit the winding DTY texturing wire.
[0040] After the winding roller 2191 on one side is wound, the drive motor 212 drives the drive disc 213 to rotate, which in turn drives one of the rotating shafts 221 to rotate. Through the transmission of two meshing gears 223, the two rotating shafts 221 can rotate relative to each other, so that the cutting blade 222 mounted on the outer surface of the rotating shaft 221 can simultaneously contact the DTY elastic wire and cut it. At the same time, the spring 2172 limits the limiting roller 2181 to limit the DTY elastic wire, preventing the elastic tension from disappearing and causing the wound DTY elastic wire to loosen.
[0041] This allows the eccentrically mounted drive block 215 to rotate, which in turn drives the driven disc 216 to rotate 180°. After rotating 180°, the drive block 215 moves away from the drive groove 2151, at which point the limiting block 214 enters the limiting groove 2141, thus limiting and fixing the driven disc 216. That is, for every rotation of the driving disc 213, the driven disc 216 rotates 180°, and the drive motor 212 stops working. The rotation of the driven disc 216 drives its rotating plate 211 to rotate 180°, thereby exchanging the positions of the completed winding roller 2191 and the new winding roller 2191. The operator... The DTY elastic wire can be re-fixed and installed on the winding roller 2191 for winding. On the other side, the wound winding roller 2191 can be disassembled and replaced. Before replacement, the electric actuator 2183 is activated, so that the support block 2184 and the top block 2182 come into contact with each other and limit it. This ensures that after the operator removes the winding roller 2191, the limiting roller 2181 will not quickly return to its original position under the force of the spring 2172. This makes it convenient for the operator to disassemble and install the winding roller 2191. After the operator removes it and installs the new winding roller 2191, the electric actuator 2183 returns to its original position, and the limiting roller 2181 returns to its original position under the force of the spring 2172 for the next use.
