Description

Technical Field

[0001] This utility model belongs to the field of nylon thread production and processing technology, and specifically relates to a hot-heating device for winding nylon thread. Background Technology

[0002] In the production of nylon yarn, winding and heat setting are two key and closely related processes. In traditional processes, after nylon yarn is spun, it is first wound onto a reel or paper tube using a winding device to form a spool. The spool is then transferred to a separate heat setting device for heat treatment to eliminate internal stress, stabilize the molecular structure, and improve the yarn's strength and dimensional stability. However, this step-by-step processing method has many technical drawbacks and has become a bottleneck restricting the efficient and high-quality production of nylon yarn.

[0003] First, in existing technologies, winding and heat setting are separate processes requiring multiple manual or mechanical transfers. This not only increases the complexity of the production process but also easily leads to thread contamination, scratches, or uneven tension during handling, affecting the final product quality. Second, because heat setting occurs after winding, the internal stress generated during winding cannot be released in time, resulting in uneven setting. Especially under high-tension winding conditions, the coil is prone to a "memory effect," causing rebound or deformation during subsequent use, severely impacting the performance of the nylon thread. Furthermore, traditional heat setting equipment is mostly batch-processing, with high energy consumption and low efficiency, making it difficult to meet the demands of modern high-speed continuous production.

[0004] A more prominent problem is that existing winding equipment generally lacks online heat treatment capabilities, making it impossible to apply controllable heat to the nylon thread in real time during the winding process. This results in the thread remaining in a high-energy state during winding, leading to defects such as uneven shrinkage, coil collapse, or interlayer slippage after cooling. This problem is particularly severe when producing high-strength, high-modulus nylon threads. Therefore, how to organically integrate winding and heat setting processes to achieve online synchronous processing has become a pressing technical challenge in this field.

[0005] Although some studies have attempted to add heating elements to winding machines, most of these methods are simple in structure, result in uneven heating, and cannot dynamically adjust the temperature according to parameters such as thread speed and tension. This leads to unstable heat setting results and may even damage the nylon thread due to localized overheating. Therefore, the current technology lacks an integrated nylon thread winding and heat setting device that is structurally sound, precisely controlled, and can be seamlessly integrated with high-speed spinning equipment.

[0006] In summary, the main technical problems existing in the prior art include: the separation of the winding and heating processes leads to low efficiency and unstable yarn quality; the lack of online heat setting function makes it impossible to eliminate internal stress in a timely manner; uneven heating and inaccurate control affect the setting effect; and low device integration makes it difficult to adapt to existing production equipment. This utility model is proposed to solve the above-mentioned technical problems. Utility Model Content

Detailed Implementation

[0023] The embodiments of this utility model are described in detail below, with reference to Figures 1 to 4This utility model provides a hot-heating device for winding nylon thread, including: a frame 10000, a fixed frame 20000, a hot-heating assembly 30000, and a winding assembly 40000. The fixed frame 20000, the hot-heating assembly 30000, and the winding assembly 40000 are fixed inside the frame 10000 from top to bottom. The hot-heating assembly 30000 includes a back plate 3100 and multiple hot-heating devices 3500 arranged side by side on the back plate 3100. The back plate 3100 is fixed to a fixed shaft plate 2100 on the fixed frame 20000. Hot-heating cylinders 3580 are fixed on both sides of the back plate 3100. The hot-heating device 3500 includes a slider device 3510 and a movable frame 352 that engages with the slider device 3510. 0. The movable frame 3520 can move up and down with the slider device 3510. A knife holder assembly 3530 is provided below the movable frame 3520. A heating tube 3560 and a thermocouple 3570 are nested inside the knife holder assembly 3530. A rolling wheel 3540 and a take-up device 3550 are provided at the bottom of the knife holder assembly 3530. The heating tube 3560 is connected to the rolling wheel 3540 to heat the rolling wheel 3540. The rolling wheel 3540 heats the tail thread evenly by rolling. The take-up device 3550 is used to take up and cut the thread. A heat insulation plate 5000 is provided between the heating assembly 30000 and the winding assembly 40000. A guide needle 4300 is provided below the winding assembly 40000. The guide needle 4300 is used to guide the nylon thread to the designated position on the take-up spool. This utility model proposes a nylon thread winding and heating device that realizes a process flow logic of upper support, middle heating, and lower winding. This allows the nylon thread to sequentially undergo heating, shaping, guiding, and winding in the vertical direction, resulting in a smooth flow and the shortest path. This effectively avoids problems such as thread jumping and uneven tension caused by structural chaos in traditional equipment. Multiple heating devices 3500 are arranged side-by-side on the back plate 3100, supporting multi-station synchronous heating. This device overcomes the technical bottlenecks of traditional winding and heating separation, excessive manual intervention, and unstable quality. It achieves online synchronous heating and shaping and automatic finishing of the nylon thread during winding. The heating component 30000, combined with the slider device 3510, L-shaped moving frame 3520, knife holder assembly 3530, and rolling wheel 3540, achieves high-temperature rolling uniform heating, effectively eliminating thread tail stress, preventing springback, and improving shaping quality. Simultaneously, the spring 3400 buffer and limiting plate structure ensures adaptive pressure adjustment, protecting the integrity of the thread. Furthermore, the integrated take-up device 3550 and the inclined blade 3551 enable automatic cutting, completing the integrated hot-cutting operation and significantly improving production efficiency.

[0024] Furthermore, referring to Figure 4The wire winding and heating device proposed in this application includes a slider device 3510 comprising a snap-fit ​​block 3511 and a moving block 3512. The first side of the snap-fit ​​block 3511 snaps into the back plate 3100. The snap-fit ​​block 3511 has grooves 3513 on both sides. The first side of the moving block 3512 has a first slot 3514. The second side of the snap-fit ​​block 3511 can snap into the first slot 3514. The first slot 3514 has protrusions 3515 on both sides. The protrusions 3515 can snap into the grooves 3513, so that the moving block 3512 can move up and down along the snap-fit ​​block 3511. This application achieves sliding guidance between the moving block 3512 and the locking block 3511 through the cooperation of the groove 3513 and the protrusion 3515. This avoids the additional installation space and high-precision machining requirements required by traditional guide rail structures, simplifies the assembly process, and reduces manufacturing costs. Secondly, the locking structure uses surface contact instead of point contact, which has strong load-bearing capacity and good vibration resistance, ensuring that there is no loosening or displacement during high-speed up-and-down movement, thus improving the stability and reliability of the slider device 3510. Furthermore, this structure allows the moving block 3512 to slide up and down along the locking block 3511, providing the roller 3540 with vertical movement freedom. Under the action of the spring 3400, it can adapt to changes in the diameter or tension fluctuations of the nylon thread, achieving flexible clamping and preventing damage to the thread or uneven heat treatment caused by insufficient pressure due to rigid contact. Furthermore, the movable frame 3520 of the wire winding and heating device proposed in this application has an L-shaped structure. The movable frame 3520 has a long limb 3521 and a short limb 3522. The long limb 3521 is vertically fixed on the back plate 3100 for mounting the movable block 3512. The first side of the long limb 3521 is provided with a second slot 3523, and the second side of the movable block 3512 can be engaged with the second slot 3523, so that the movable block 3512 drives the movable frame 3520 to move up and down. The L-shaped structure has superior mechanical properties. The long limb 3521 provides vertical support stiffness, while the short limb 3522 serves as a lateral extension arm for mounting the tool holder assembly 3530, forming a stable cantilever support structure that can withstand the weight and impact force of the wire rolling wheel 3540 in the heating state, preventing structural deformation or vibration. Moreover, engaging the movable block 3512 with the second slot 3523 of the long limb 3521 makes the power transmission path clear and direct, reduces intermediate connecting parts, and improves transmission efficiency and response speed. Furthermore, this structure ensures that the movement trajectory of the roller 3540 is perpendicularly aligned with the direction of travel of the nylon thread, guaranteeing that the roller 3540 can roll and press evenly over the end of the thread, avoiding uneven pressing or damage to the thread caused by bias pressure.

[0025] Furthermore, referring to Figure 3The tool holder assembly 3530 includes a tool holder fixing frame 3531 and a tool holder 3532. The tool holder fixing frame 3531 is fixed to the short limb 3522, and the tool holder 3532 is fixed to the side of the tool holder fixing frame 3531. A heat insulation plate 5000 is fixed between the tool holder fixing frame 3531 and the tool holder 3532. The side of the tool holder fixing frame 3531 is provided with a locking plate 3533, which can be locked onto the upper side of the short limb 3522 to fix the tool holder fixing frame 3531 to the movable frame 3520. The blade holder 3532 is fixed to the lower side of the blade holder fixing frame 3531. The upper surface of the blade holder 3532 has multiple parallel through holes 3534, into which the heating element 3560 and thermocouple 3570 can be inserted. The lower surface of the blade holder 3532 has a baffle 3535 and a support rod 3536. The wire rolling wheel 3540 can be fitted onto the support rod 3536, so that the baffle 3535 is fixed to both sides of the wire rolling wheel 3540. A wire take-up device 3550 is provided on one side of the baffle 3535, and the lower end of the take-up device 3550 has an inclined blade 3551. The blade holder fixing frame 3531 serves as an intermediate connector, firmly mounting the blade holder 3532 to the short limb 3522 of the movable frame 3520, ensuring that the blade holder 3532 moves up and down synchronously with the movable frame 3520, achieving precise control of the wire heating action. The tool holder 3532 is fixed to the side of the tool holder fixing frame 3531, forming a horizontal installation structure, which facilitates the layout and maintenance of components such as the heating element 3560, thermocouple 3570, and roller 3540. More importantly, a heat insulation plate 5000 is set between the tool holder fixing frame 3531 and the tool holder 3532, forming a crucial thermal isolation barrier. Since the heating element 3560 operates at a temperature as high as 380℃, if heat is directly conducted to the tool holder fixing frame 3531 and the moving frame 3520, it may cause thermal expansion, deformation, or even damage to the metal parts, affecting the motion accuracy and equipment lifespan. Of course, this application does not limit the specific material of the heat insulation plate 5000. Preferably, the heat insulation plate 5000 is made of ceramic or fiberglass material. The heat insulation plate 5000 effectively blocks the conduction path of high temperature to the structural components, protecting the precision moving parts above and ensuring long-term stable operation of the equipment. At the same time, the heat insulation plate 5000 can also prevent heat from diffusing upward to the back plate 3100 or the slider device 3510, avoiding affecting the normal operation of other components. The through-hole 3534 design allows the heating element 3560 and thermocouple 3570 to be vertically inserted into the knife holder 3532, ensuring secure installation and good contact. This guarantees efficient heat transfer to the roller 3540, while the thermocouple 3570 can monitor the temperature in real time, achieving closed-loop control. Of course, this application does not limit the specific number of through-holes 3534; preferably, there are two through-holes 3534. (Refer to...) Figure 3The support rod 3536 and the baffle 3535 cooperate to form an axial limiting structure for the rolling wheel 3540, preventing axial displacement or detachment during rolling and ensuring a stable and reliable hot-pressing process. The rolling wheel 3540 is sleeved on the support rod 3536 and can rotate freely. It contacts the nylon thread tail through rolling rather than static pressing, reducing friction damage and achieving uniform heat transfer to avoid local overheating and carbonization. Of course, this application does not limit the specific location of the take-up device 3550. Preferably, the take-up device 3550 is integrated into one side of the baffle 3535. Its inclined blade 3551 can automatically press down after hot-pressing, using the inclined plane principle to cut the thread and complete the automatic tailing. The inclined design makes the cutting force more concentrated, the cut cleaner, and avoids fraying or residue.

[0026] Furthermore, the hot-rolling assembly 30000 also includes an upper limit plate 3200 and a lower limit plate 3300 fixed to the upper and lower end faces of the back plate 3100. A spring 3400 is provided between the upper limit plate 3200 and the slider device 3510. The spring 3400 is used for cushioning to ensure that the rolling wheel 3540 and the nylon thread are in contact. This design solves the key problem of pressure control during high-temperature rolling. The upper limit plate 3200 and the lower limit plate 3300 together constitute the motion limiting structure of the slider device 3510, preventing its vertical movement from exceeding the safe range and avoiding equipment damage or safety accidents. The upper limit plate 3200 limits the upward height of the slider to ensure that the rolling wheel 3540 is completely disengaged from the thread when not in operation; the lower limit plate 3300 prevents the slider from excessively pressing down, which could damage the thread or overload the structure. Of course, this application does not limit the fixing method of the upper and lower limit plates 3200, 3300 and the back plate 3100. Preferably, the upper and lower limit plates 3200, 3300 are fixed to the back plate 3100 by screws. The spring 3400 is disposed between the upper limit plate 3200 and the slider device 3510, providing a downward elastic preload, so that the rolling wheel 3540 can continue to adhere to the surface of the nylon thread after descending. Even if there are slight fluctuations in the thread diameter or changes in tension, the pressure can be adaptively adjusted to achieve "flexible pressing". This buffering mechanism effectively avoids impact damage caused by rigid contact and protects the surface integrity of the nylon thread. At the same time, the constant elastic pressure ensures stable contact thermal resistance between the rolling wheel 3540 and the thread, uniform heat transfer, and consistent heat-pressing effect. Furthermore, referring to... Figure 1 and Figure 2This application proposes a semi-enclosed mounting chamber 1100 inside the frame 10000 of the winding and coiling device. The fixing frame 20000, the hot-heating assembly 30000, and the winding assembly 40000 are all fixed inside the mounting chamber 1100. The fixing frame 20000 is located above the hot-heating assembly 30000, and the winding assembly 40000 is located below it. An operating platform 1200 is located at the front of the mounting chamber 1100, and an electrical box 1300 is located on the side of the frame 10000. Below the electrical box 1300 are two openable storage cabinets 1400. The semi-enclosed mounting chamber 1100 centrally encapsulates the core functional components, forming an independent working area, effectively preventing external dust and oil from entering, protecting precision components, and extending equipment life. Simultaneously, the chamber structure enhances the overall rigidity of the frame 10000, reducing operational vibration. The operating platform 1200, located at the front, is used to place the parts after winding and hot-heating.

[0027] Furthermore, the fixed frame 20000 includes a fixed shaft plate 2100, a lighting fixed sheet metal 2200, and an anti-skid wire fixing rod 2300, which are fixed above the fixed shaft plate 2100. The fixed shaft plate 2100 serves as the core mounting reference, providing a stable connection for the back plate 3100, slider device 3510, etc., ensuring the installation accuracy of the heat-setting assembly 30000. The lighting fixed sheet metal 2200 is used to install lighting fixtures, providing sufficient light to the operating area, especially at night or in low-light conditions, facilitating operators to observe the wire condition, heat-setting effect, and equipment operation, thus improving operational safety and accuracy. The anti-skid wire fixing rod 2300 is positioned appropriately above to limit the vertical jump of the nylon wire during high-speed operation, preventing it from detaching from the guide wheel or tangling on other components, thus avoiding "skid wire" malfunctions. This rod is typically a smooth metal rod with a polished surface or a wear-resistant sleeve to reduce frictional damage to the wire. All three components are integrated into a single fixed frame 20000, resulting in a compact structure and easy installation. More importantly, this design organically combines functional auxiliary components (lighting, anti-drop wires) with structural support components (fixed shaft plate 2100), avoiding structural confusion and insufficient strength issues that can result from later additions. The position of the anti-drop wire pole is adjustable to accommodate different wire diameters and tension requirements.

[0028] Furthermore, the winding assembly 40000 includes a wire guide rod 4100, with multiple parallel felt fasteners 4200 above the wire guide rod 4100, multiple parallel guide pins 4300 below the wire guide rod 4100, and multiple parallel winding spindles 4400 below the wire guide rod 4100. The side plate of the winding spindle 4400 has a wire clamp 4500. This design achieves precise control throughout the winding process. The wire guide rod 4100 is used for reciprocating movement to achieve uniform distribution of the nylon thread on the take-up spool, preventing interlayer compression or gaps. The felt fasteners 4200 are used to install felt strips; the felt makes slight contact with the surface of the nylon thread, serving a cleaning function to remove dust and oil, ensuring the thread enters the take-up area cleanly and preventing impurities from affecting the winding quality or contaminating the winding roller 3540. The guide pins 4300 precisely guide the thread into the starting position of the take-up spool, ensuring a neat first turn and avoiding tangled thread at the beginning. Multiple parallel guide pins 4300 can accommodate multi-station winding needs. The winding spindle 4400 drives the take-up shaft to rotate, achieving constant tension winding. The excess wire clamp 4500 is located on the side plate of the spindle and is used to clamp the wire tail during roll changes or machine stops to prevent it from loosening, springing back, or tangling, facilitating quick splicing of the next roll and improving work continuity and efficiency.

[0029] When the winding and heating device of this application is in operation, the operator sequentially passes the end of the nylon thread through the guide needle, tension adjusting roller, and excess thread clamp 4500, guiding it to the starting position of the take-up shaft. Then, the thread end is passed through the felt assembly and finally introduced into the roller 3540 area of ​​the heating unit. At this time, the take-up shaft is in standby mode, and the excess thread clamp 4500 is in a clamping state, fixing the thread end and preventing it from loosening. After the equipment is started, the main drive motor drives the take-up shaft to rotate, generating initial winding tension. The control system issues a command, and the excess thread clamp 4500 automatically releases. Under the action of tension, the nylon thread is driven forward by the take-up shaft, and the first turn of thread begins to wind onto the I-beam or paper tube, achieving stable winding. As the nylon thread passes through the tension adjusting roller, the system monitors and adjusts the tension in real time to ensure constant tension during winding, avoiding damage to the thread due to excessive tightness or slippage between layers due to excessive looseness. Simultaneously, the guide needle precisely guides the thread, working in conjunction with the thread laying mechanism to achieve uniform winding, ensuring the coil is neat and tight. When the nylon thread passes through the heat-setting assembly 30000, the heating element 3560 is energized and heated to the set temperature (e.g., 380℃), and the heat is transferred to the roller 3540 through the heat-conducting structure. Thermocouple 3570 detects the temperature in real time and feeds the signal back to the temperature control system to achieve closed-loop temperature control. Under the elastic pressure of spring 3400, the slider moves downward along the guide rail on the fixed shaft plate 2100, driving the roller 3540 to press the nylon thread. During the movement, the nylon thread comes into contact with the high-temperature roller 3540, the surface softens due to heat, and the internal stress is released, completing the online heat setting of "winding and heating at the same time". Multiple heat-setting units 3500 are arranged in parallel to ensure that the thread is uniformly heated in different positions, improving the consistency of setting. When a roll of nylon thread is wound and the equipment stops, the control system automatically triggers the action of the excess thread clamp 4500 to close it and clamp the current thread end to prevent the thread end from springing back or loosening. At this point, the winding shaft stops rotating, and the operator can change rolls, cut threads, or remove finished thread rolls.
