Description

Technical Field

[0001] This invention relates to the field of textile fabric processing equipment, specifically to a shaping and processing equipment for intelligent temperature-regulating textile fabric production. Background Technology

[0002] As consumers increasingly demand comfort and functionality in clothing, intelligent temperature-regulating textiles, with their ability to automatically adjust perceived temperature based on changes in ambient or body temperature, have gained widespread application in the textile industry. Heat setting, a crucial finishing process for these fabrics, directly determines two core quality aspects: smoothness and temperature regulation. Wrinkles remaining before the fabric enters the high-temperature environment will be permanently cured, rendering it a defective product. The stability of the temperature-regulating function is also critical; the phase-change temperature-regulating materials within the fabric are extremely sensitive to temperature. Temperature deviations from the optimal range (e.g., decomposition above 60℃ or inability to set below 45℃) or excessively rapid temperature changes will cause the fabric to lose its core temperature-regulating properties. Therefore, non-destructive, high-precision flattening and precise zoned temperature control are the core technical points for the heat setting process of intelligent temperature-regulating fabrics.

[0003] Currently, the fabric smoothing process before setting mainly relies on two methods: manual smoothing and mechanical smoothing devices. Manual smoothing is labor-intensive and inefficient, and its quality depends heavily on the worker's experience and focus, making it a bottleneck for overall efficiency and quality improvement on continuous, high-speed production lines. Simple mechanical devices such as threaded smoothing rollers and air-cushion spreaders can only solve the problem of fabric edge curling; they are ineffective at addressing the fine wrinkles caused by stacking and compression. Furthermore, mechanical contact can easily scratch the surface of thin, highly sensitive intelligent temperature-regulating fabrics, leading to product scrap.

[0004] To address the aforementioned issues, the industry has seen the emergence of shaping and processing equipment, such as the one disclosed in patent CN120138919A. This equipment, by adding a tension adjustment component, a heat recovery box, and a double-sided heating structure, mitigates some of the shortcomings of traditional equipment: the tension adjustment component can adjust the spacing and height of the conveyor rollers in real time, reducing wrinkles caused by uneven tension; the heat recovery box can recover some waste heat, reducing energy consumption. However, this equipment still has unavoidable technical shortcomings in meeting the core processing requirements of intelligent temperature-regulating fabrics, specifically: Firstly, the smoothing precision is insufficient, and the risk of minor wrinkles and mechanical damage remains. This equipment relies solely on a passive mode of indirectly preventing wrinkles by adjusting tension, lacking an active, multi-stage, interconnected smoothing mechanism. For the minor wrinkles generated during the stacking and conveying of intelligent temperature-regulating fabrics, simply changing the spacing of the conveyor rollers cannot effectively smooth them out; moreover, its tension adjustment relies on mechanical contact structures such as lead screws and hydraulic telescopic mechanisms, which still pose a risk of stretching deformation or surface scratches for highly elastic and sensitive fabrics, making it difficult to meet the requirements of high-end fabrics for physical integrity.

[0005] Secondly, the temperature control lacks zoned and dynamic adaptation capabilities, resulting in a high risk of functional failure. The device employs an integrated heating mode. Although it monitors temperature thresholds through an array of temperature sensors, it lacks specific temperature zones, failing to match the phased temperature requirements of the intelligent temperature-regulating fabric during preheating, main shaping, and functional curing. The preheating stage requires slow heating to avoid internal stress; the main shaping stage requires a constant temperature (e.g., 50-55℃) to ensure shape stability; and the functional curing stage requires gradient cooling to lock in temperature regulation performance. Furthermore, its temperature regulation relies solely on passive logic of heat dissipation and recycling after exceeding limits, lacking dynamic control over heating, holding, and cooling rates. This can easily lead to irreversible failure of the phase change material due to temperature fluctuations or excessively rapid changes.

[0006] Third, the lack of wrinkle detection and targeted smoothing results in poor fabric flatness consistency. The equipment lacks a wrinkle detection device, relying solely on tension data to indirectly determine fabric smoothness, thus failing to identify minor local wrinkles. Furthermore, the absence of a targeted smoothing structure means that even if wrinkles are detected, the only solution is to adjust the overall tension, leading to inconsistent flatness across different areas of the fabric and affecting product quality uniformity. Summary of the Invention

[0007] The purpose of this invention is to overcome the above-mentioned problems.

[0008] To achieve the above objectives, the technical solution adopted by the present invention to solve its technical problem is as follows: Design a setting and finishing equipment for intelligent temperature-controlled textile fabric production, the specific solution of which is as follows: A shaping and processing equipment for intelligent temperature-regulating textile fabric production includes a processing box and a conveying system installed inside the processing box. The processing box is also equipped with a multi-stage flattening system, an electromagnetic drive system, and a zoned temperature control system. The conveying system includes multiple conveyor rollers arranged along the fabric conveying path. The multi-stage flattening system includes a first-stage flattening mechanism, a second-stage flattening mechanism, and a third-stage flattening mechanism arranged sequentially along the fabric conveying direction. The first-stage flattening mechanism is used to perform basic wrinkle removal on the fabric, and the second-stage flattening mechanism is used to press and sweep the fabric after the first-stage flattening. The two form a stepped ironing cooperation. The electromagnetic drive system includes a piston cylinder, a piston assembly disposed within the piston cylinder, an electromagnetic coil assembly disposed outside the piston cylinder, and a one-way valve connected to the intake and exhaust pipes. The electromagnetic drive system is connected to a multi-stage paving system through the intake and exhaust pipes. The zoned temperature control system is located downstream of the multi-stage paving system and is divided into multiple independent temperature zones along the fabric conveying direction.

[0009] Furthermore, the primary leveling mechanism includes a push rod cylinder, a blade body, a central rotating shaft, a flap door assembly, a ratchet mechanism, and a push rod; The pushrod cylinder body is equipped with a main air inlet, which is connected to the electromagnetic drive system through a pipe; The blade body is rotatably mounted in the push rod cylinder via a central rotating shaft, located on one side of the main air intake. The flap assembly is located on the other side of the main air intake and is hinged to the inner wall of the push rod cylinder. The flap assembly includes a flap body, a hinge shaft and a door torsion spring. The flap body is configured to open in one direction toward the rotation direction of the blade body. The push rod is fixedly connected to the central rotating shaft; The trapdoor body and the blade body work together under the action of high-pressure gas to form a variable-volume sealed air chamber.

[0010] Furthermore, the central rotating shaft is equipped with a central air passage and radial vents; The push rod has an L-shaped structure, including a vertical section connected to the central pivot and a horizontal section extending along the width of the fabric; The push rod has an air passage that connects to the central air passage. The inner wall of the air passage is equipped with an auxiliary heating element to heat the push rod and the airflow passing through it simultaneously. The horizontal section of the side wall is evenly provided with multiple small jet holes.

[0011] Furthermore, the secondary leveling mechanism includes a sweeping rod cylinder, fixed blades, drive blades, a hollow fixed rotating shaft, a telescopic drive assembly, and a sweeping rod; The fixed blade is fixed inside the sweeper cylinder, and the drive blade is coaxially set with the fixed blade through a hollow fixed rotating shaft; The fixed blades and the drive blades divide the inside of the sweeper cylinder into a drive chamber and a guide chamber; The hollow fixed rotating shaft has an axial channel inside, and the side wall of the axial channel has a vent hole that is always connected to the drive cavity. The sweeping rod is a long strip structure that extends along the width of the fabric, and its end is fixedly connected to the end of the hollow telescopic rod. The drive chamber is equipped with a drive air inlet, which is connected to the electromagnetic drive system. The bottom of the guide cavity is equipped with a pressure relief and exhaust port.

[0012] Furthermore, a return torsion spring is provided between the drive blade and the sweeper cylinder; When the drive blade rotates under air pressure until the pressure relief port connects with the drive chamber, the drive chamber is depressurized, and the drive blade is reset by the action of the reset torsion spring.

[0013] Furthermore, the telescopic drive assembly includes a hollow guide rod, a hollow telescopic rod, and a pre-tensioned compression spring; One end of the hollow guide rod is connected to the hollow fixed rotating shaft, and its internal channel is connected to the axial channel; The hollow telescopic rod and the hollow guide rod slide together. The pre-tensioning compression spring is positioned between the hollow guide rod and the hollow telescopic rod.

[0014] Furthermore, the three-tiered paving mechanism includes: The infrared detection device includes an infrared transmitter and an infrared receiver to monitor the surface condition of the fabric. The signal processing module is electrically connected to the infrared detection device; The jetting system includes a main air duct, multiple zone branch pipes, and jet nozzles, with each zone branch pipe equipped with an independent control valve.

[0015] Furthermore, the zoned temperature control system includes: The three independent temperature zones are, in order along the fabric conveying direction, the preheating zone, the main shaping zone, and the functional curing zone, with heat insulation panels between each temperature zone; Three independent heating devices are installed in their respective temperature zones; Multiple infrared temperature sensors are installed inside each temperature zone to monitor the surface temperature in real time; The temperature control module is electrically connected to the heating device and infrared temperature sensor, and achieves independent temperature control of each temperature zone through a PLC controller.

[0016] A method for setting textile fabrics based on a setting equipment for intelligent temperature-regulating textile fabric production includes the following steps: S1. Input the fabric to be processed into the processing box and convey it along the set path by the conveyor rollers; S2. The push rod of the first-level flattening mechanism performs lifting and circular motion to perform preliminary mechanical flattening and wrinkle removal on the fabric, while the hot airflow ejected by the push rod softens the fibers. S3. The sweeping bar of the secondary flattening mechanism performs downward pressure and arc sweeping motion, pressing the fabric tightly against the push bar surface to enhance the wrinkle removal effect, and using its friction to assist in delivering the fabric; S4. The three-stage smoothing mechanism detects the surface condition of the fabric through an infrared detection device and controls the air jet device to precisely smooth out the wrinkled areas with air jets. S5. The laid-out fabric is conveyed to the zoned temperature control system, where it is sequentially heated and shaped through the preheating zone, main shaping zone, and functional curing zone. S6. Output the shaped fabric.

[0017] Furthermore, step S3 specifically includes the following steps: S31. As the push rod lifts the fabric upward and forms a supporting curved surface, the sweeping rod moves downward simultaneously; S32. The sweeping bar contacts the fabric and presses it firmly against the lifting surface of the push bar; S33. Under the clamping state, the sweeping bar sweeps in an arc with the rotation of the drive blade, smoothing the material and delivering it forward using friction. S34. After delivery is completed, the sweeping bar retracts upward and resets, and the push bar resets simultaneously.

[0018] The beneficial effects of this invention are: 1. The first-level mechanism uses mechanical push rods and hot airflow to quickly rough flatten the fabric and eliminate large wrinkles; the second-level mechanism uses a combination of pressing and sweeping actions to eliminate internal fiber stress and fine wrinkles; the third-level mechanism uses infrared detection to perform pinpoint air jet finishing, overcoming the limitations of a single flattening method and ensuring that the fabric reaches a near-flat state before entering the high-temperature setting zone.

[0019] 2. The heating and setting zone is divided into three independent temperature zones, which are monitored in real time by infrared sensors to ensure a perfect match between the temperature curve and the fabric setting process. At the same time, the heat absorption cover assembly can efficiently recover excess heat and convert it into electrical energy for storage and reuse through thermoelectric power generation technology, effectively solving the problems of high energy consumption and low thermal efficiency of traditional setting equipment, thus achieving both environmental protection and economic benefits.

[0020] 3. This invention, through the design of pipeline air path distribution and action phase connection between the electromagnetically driven piston and the first and second stage leveling mechanisms, allows a single piston to reciprocate and drive the first stage push rod to lift the fabric and the second stage sweeping rod to compact and sweep, and then reset sequentially, through synchronous gas output and orderly depressurization. This achieves non-interference collaborative leveling of the two-stage mechanisms under a single power source, significantly reducing the energy consumption of traditional multi-pump systems and improving the coordination accuracy of mechanism actions.

[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments, and not all embodiments.

[0024] In the description of this invention, it should be understood that the terms "front", "rear", "left", "right", "upper", "lower", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0025] refer to Figure 1-15This invention provides an intelligent temperature-controlled textile fabric production and setting equipment, including a processing chamber 1, a conveying system, a multi-stage flattening system, an electromagnetic drive system, and a zoned temperature control system. Each system is modularly integrated within the processing chamber 1 and functionally divided into a feeding area, a flattening processing area, a heating and setting area, and a discharging area. Each area is continuously and stably conveyed by conveyor rollers 2 of the conveying system. The zoned temperature control system adopts a sealed structure design. An observation window 74 is provided on the side wall of the processing chamber 1, allowing operators to monitor the fabric processing status in real time. An inspection door is also provided for convenient equipment maintenance. The interior of the chamber is insulated to effectively prevent heat loss and reduce energy consumption.

[0026] In practical implementation, the conveying system includes multiple conveyor rollers 2, which are arranged along the fabric conveying route and cooperate with multiple systems. Specifically, in the feeding area, a set of conveyor rollers 2 is responsible for receiving and guiding the fabric to be processed; in the flattening area, conveyor rollers 2 are interspersed before and after the primary, secondary, and tertiary flattening mechanisms to support and stably convey the fabric before and after each flattening action; in the heating and setting area, conveyor rollers 2 are evenly distributed at the inlet and outlet and inside of the preheating area 70, the main setting area 71, and the functional curing area 72 to ensure that the fabric moves smoothly and remains flat during heating; in the discharge area, the conveyor rollers 2 smoothly output the set fabric. All conveyor rollers 2 are driven by stepper motors, their surfaces are covered with an anti-slip rubber layer, and their speed can be steplessly adjusted by a PLC control system to adapt to the conveying requirements of different fabrics.

[0027] In practical implementation, the electromagnetic drive system is located at the bottom of the feeding area and includes a piston cylinder 3, a piston assembly 30, an electromagnetic coil group, a one-way valve, an intake and exhaust pipe, and a circulation pipe. The piston cylinder 3 has a rectangular cavity structure with end caps at both ends. The end caps are fixed to the cylinder with bolts, and a sealing gasket is provided on the inside of the end cap to ensure the sealing of the cylinder. Multiple electromagnetic coil mounting slots are provided on the side wall of the cylinder. The mounting slots are evenly arranged along the circumference of the cylinder and are divided into two groups according to color. The electromagnetic coils in each group are symmetrically arranged to form a magnetic pole opposing structure.

[0028] The piston assembly 30 includes a piston body and a sealing ring. The piston body is slidably disposed inside the piston cylinder 3. The outer side wall of the piston body fits against the inner side wall of the cylinder. The sealing ring is fitted into the annular groove of the piston body to ensure the sealing performance between the piston and the cylinder and prevent gas leakage.

[0029] The electromagnetic coil assembly includes a first set of electromagnetic coils and a second set of electromagnetic coils. The two sets of coils are respectively installed in corresponding mounting slots on the side wall of the cylinder. The coils are wound with high-temperature resistant enameled wire, and the coil leads are electrically connected to a PLC controller. The controller controls the current direction and on / off state of the coils. An internal electromagnetic coil is located inside the piston body. The current direction of the internal electromagnetic coil remains constant, ensuring its magnetic pole direction is fixed, and creating an attractive or repulsive force with the electromagnetic coil assembly on the outside of the cylinder.

[0030] The one-way valve includes an intake one-way valve and an exhaust one-way valve. The intake one-way valve is installed on the intake pipe of the piston cylinder 3 and only allows gas to enter the cylinder from the outside or the circulation pipe. The exhaust one-way valve is installed on the exhaust pipe of the piston cylinder 3 and only allows gas to be discharged from the cylinder to the components of the paving system, thus preventing gas backflow.

[0031] The intake and exhaust pipes include a main intake pipe and a main exhaust pipe. One end of the main intake pipe is connected to an external air source, and the other end is connected to the intake port of the piston cylinder 3. One end of the main exhaust pipe is connected to the exhaust port of the piston cylinder 3, and the other end is connected to the intake ports of the push rod 45 assembly and the sweep rod assembly through the main pipe 31 and the branch pipe 32, respectively.

[0032] In practice, the PLC controller of the electromagnetic drive system is electrically connected to each detection device of the leveling system. Based on the detection signals, it adjusts the current parameters of the electromagnetic coil in real time to control the piston's movement speed and gas output pressure. A flow controller is installed on the air intake pipe of the piston cylinder 3 to regulate the gas flow rate entering the cylinder and adapt to the gas requirements of different leveling mechanisms.

[0033] When the equipment starts, the PLC controller supplies a positive current to the first set of electromagnetic coils, causing these coils to generate magnetic poles opposite to those of the piston's internal coil, creating a repulsive force. Simultaneously, a reverse current is supplied to the second set of electromagnetic coils, causing these coils to generate magnetic poles identical to those of the piston's internal coil, creating an attractive force. Under the combined action of the repulsive and attractive forces, the piston slides rapidly along the cylinder towards the second set of coils. The gas inside the cylinder is compressed, the inlet check valve closes, and the outlet check valve opens. The compressed gas is then transported through the main outlet pipe to the push rod 45 assembly, the sweeping rod assembly, and the jetting device 60, providing power for the leveling action.

[0034] When the piston moves to the end of the cylinder, the PLC controller switches the current direction of the two sets of electromagnetic coils: the first set of coils receives a reverse current, generating the same magnetic pole as the piston's internal coil, creating an attractive force; the second set of coils receives a forward current, generating the opposite magnetic pole to the piston's internal coil, creating a repulsive force. Under the action of the attractive and repulsive forces, the piston returns to its original position along the cylinder towards the first set of coils. At this time, a negative pressure is formed inside the cylinder, the intake check valve opens, and gas from the external air source and the circulation pipe enters the cylinder to replenish the gas volume, preparing for the next compression.

[0035] By alternately switching the current direction of the two sets of electromagnetic coils, the piston can reciprocate linearly within the cylinder, continuously generating compressed gas and providing stable and continuous power for the multi-stage leveling mechanism.

[0036] Example 1 In practice, the flattening treatment area is equipped with a multi-level flattening system, which includes a first-level flattening mechanism, a second-level flattening mechanism, and a third-level flattening mechanism. The three mechanisms are arranged sequentially along the fabric conveying direction to achieve a step-by-step flattening from coarse adjustment to fine adjustment, ensuring that the fabric is wrinkle-free and stretch-free before entering the heating and setting area.

[0037] In practical implementation, the primary leveling mechanism, as a coarse adjustment mechanism, is mainly used to quickly eliminate large wrinkles and stacking on the fabric surface caused by winding and conveying. It includes push rod cylinder 4, blade assembly, flap door assembly, reset torsion spring, ratchet mechanism 43, push rod 45 and auxiliary heating element.

[0038] The push rod cylinder 4 is a cylindrical cavity structure, which is horizontally installed on the side wall inside the processing box 1. The top of the cylinder is provided with a main air inlet 40, which is connected to the main air outlet of the electromagnetic drive system through an air pipe. The cylinder body of the push rod cylinder 4 is sealed to the ratchet mechanism 43.

[0039] In specific implementation, the blade assembly includes a blade body 41, a central rotating shaft 42, and a bushing. The blade body 41 is made of lightweight, high-strength alloy material and has a fan-shaped structure to ensure sufficient thrust and stroke. The outer edge of the blade body 41 is tightly fitted with the inner wall of the push rod cylinder 4 to prevent air leakage. In the initial position, the end of the blade body 41 is located downstream of the main air intake 40. The central rotating shaft 42 is a hollow shaft structure. One end of it is rotatably supported on the center of the inner wall of the push rod cylinder 4 through a bushing and bearing. The other end passes through the center of the ratchet mechanism 43 and is fixedly connected to the push rod 45. The interior of the central rotating shaft 42 is a central air passage, and multiple radial ventilation holes 420 are opened near the main air intake 40. These radial ventilation holes 420 connect the central air passage with the internal space of the cylinder.

[0040] In practice, the flap assembly is installed on the inner wall of the push rod cylinder 4. In its initial position, it is located upstream of the main air inlet 40. Its function is to cooperate with the blade assembly to form a variable-volume sealed air chamber. It includes the flap body 44, the hinge shaft, and the flap torsion spring, which allows it to open only in one direction. The flap body 44 is made of stainless steel plate, and its shape matches the inner wall of the cylinder. It can form an effective seal when closed. A silicone sealing gasket is embedded around the edge of the flap to enhance airtightness. The flap body 44 is rotatably mounted on the bracket on the inner wall of the cylinder through the hinge shaft. The flap torsion spring is sleeved on the hinge shaft, with one end fixed to the flap body 44 and the other end fixed to the protrusion on the side wall of the cylinder. Under normal conditions, the flap torsion spring is in its natural state, pressing the flap body 44 against the stop surface of the cylinder to keep it closed, thus forming an initial sealed air chamber together with the blade body 41 of the blade assembly.

[0041] In practical implementation, the ratchet mechanism 43 limits the blade assembly to rotate only in one direction, ensuring the stability of the push rod 45's movement trajectory and preventing it from rotating in the opposite direction when the gas pressure is released or reset, thereby preventing unnecessary pulling or damage to the fabric. The ratchet mechanism 43 is an annular shell structure, with its outer edge sealed to the inner wall of the push rod cylinder 4, forming a sealed cavity inside, and an air hole connected to the main air inlet 40 is provided at the top. A ring of ratchet teeth is machined on the inner wall of the ratchet mechanism 43. On the outer edge of the fan-shaped blade body 41 of the blade assembly, corresponding to the position of the ratchet teeth, there is a retractable pawl 410. A small compression spring is provided between the pawl 410 and the blade body 41, keeping the pawl 410 always pressed against the ratchet teeth. When the blade body 41 rotates clockwise, the pawl 410 can smoothly slide past the ratchet teeth. When the blade body 41 has a tendency to rotate counterclockwise, the pawl 410 will rigidly engage with the tooth surface of the ratchet teeth, thereby preventing it from rotating in the opposite direction. A magnet 411 is provided on the top of the pawl 410, and a magnet 412 is provided on the inner wall of the ratchet mechanism 43. The magnet 411 and the magnet 412 attract each other, and the magnet 412 is located at the position corresponding to the initial position of the blade body 41, which is used to drive the blade body 41 to reset.

[0042] In practice, the push rod 45 is the actuating end that directly acts on the fabric. It is made of metal tubing and is L-shaped. One end of the push rod is fixedly connected to the outer end of the central rotating shaft 42 of the blade assembly and is connected to the central air passage of the central rotating shaft 42. The other end of the push rod is perpendicular to the direction of the fabric's movement and its length is slightly greater than the maximum width of the fabric being processed to ensure that it can cover the entire width of the fabric. On the lower side wall of the horizontal section of the push rod 45, there are multiple air jet holes 451 with a diameter of 0.5-1mm. These air jet holes 451 are connected to the air passage inside the push rod 45 and then connected to the internal space of the cylinder through the radial ventilation hole 420 of the central rotating shaft 42. To enhance the smoothing effect, an auxiliary heating element is embedded inside the side wall of the push rod cylinder 4. This heating element is preferably an electric heating wire, such as Cr20Ni80 high-temperature resistance wire, which is wound around the inner wall of the push rod 45. The heating wire is electrically connected to the temperature control module of the equipment, and can heat the push rod 45 to a preset temperature as needed. At the same time, it heats the airflow inside the push rod 45. The heated push rod 45 can not only physically smooth out wrinkles, but also soften the fabric fibers, reduce their frictional resistance and internal stress during the smoothing process, and achieve a softer and more effective smoothing.

[0043] In practice, the main air inlet 40 of the push rod cylinder 4 of the first-stage paving mechanism is connected to the main air outlet pipe of the electromagnetic drive system through a pipe. An electromagnetic flow regulating valve is connected in series on the pipe. This valve is electrically connected to the PLC control system and can adjust the gas pressure and flow rate entering the cylinder according to the material, thickness and other characteristics of the fabric, thereby controlling the rotation speed and thrust of the push rod 45.

[0044] The specific working process of the first-stage leveling mechanism is as follows: When the high-pressure gas output by the electromagnetic drive system enters the push rod cylinder 4 through the main air inlet 40 and enters the ratchet structure through the air hole, the gas is confined in the initial closed air chamber formed by the flap door body 44 and the blade body 41 because the flap door assembly is in a closed state. As the gas continues to be filled, the pressure in the air chamber rises rapidly. When the pressure in the air chamber reaches the preset threshold and is sufficient to overcome the resistance of the blade assembly rotation, the high-pressure gas will push the blade body 41 to rotate in a clockwise direction. The blade body 41 drives the central rotating shaft 42 to rotate synchronously, thereby driving the push rod 45 to perform circular motion with the central rotating shaft 42 as the center. During the circular motion of push rod 45, its horizontal section gradually rises from below the conveyor roller 2, contacts and gently lifts the fabric, and then moves with the fabric, initially smoothing and flattening the folds formed by stacking and squeezing in the horizontal direction. At the same time, due to the increase in pressure inside the cylinder, some high-pressure gas enters the central air passage through the radial ventilation hole 420 of the central rotating shaft 42, then flows through the internal air passage of push rod 45, and finally is ejected at high speed from the jet hole 451 of its horizontal section. This airflow blows onto the surface of the fabric being smoothed by the machine, further smoothing the fine folds that are difficult to eliminate by mechanical action, and softening the fibers, thus improving the smoothing effect. When the blade body 41 rotates to the point where its outer edge is about to contact the free end of the trapdoor body 44, with the continuous action of gas pressure and the mechanical compression of the blade body 41, the trapdoor body 44 begins to overcome the elastic force of the door torsion spring and rotates counterclockwise around the hinge axis to achieve the opening action. This allows the high-pressure gas in the cylinder to be quickly depressurized through the channel between the opened trapdoor and the blade body 41, preparing for the next cycle. After the gas is depressurized, the blade assembly loses its driving force. When the gas pressure disappears, the magnetic pull pulls the blade and push rod 45 back to the initial position. During the reset process, due to the one-way locking action of the ratchet mechanism 43, the blade assembly will not rotate counterclockwise, ensuring the stability of the reset path. After the blade is reset, the trapdoor body 44 closes again under the action of the door torsion spring, waiting for the next working cycle. Through the above cyclic process, the primary leveling mechanism achieves continuous and efficient coarse leveling of the fabric.

[0045] Example 2 The secondary leveling mechanism eliminates residual fine wrinkles and internal fiber stress in the fabric through a combination of pressing, sweeping, and delivering actions. Its lifting synergy with the primary leveling mechanism prevents fabric instability caused by airflow disturbances and ensures the fabric fully adheres to the primary push rod 45, enhancing the initial leveling effect. The secondary leveling mechanism mainly consists of a sweeping rod cylinder 5, fixed blades 50, drive blades 51, a hollow fixed rotating shaft 52, a telescopic drive assembly, a sweeping rod 53, and a reset assembly.

[0046] In practice, the sweeping rod cylinder 5 is an integrated cavity structure, fixedly connected to the inner wall of the processing box 1, and located downstream of the first-stage leveling mechanism. The interior of the sweeping rod cylinder 5 forms functional zones through the cooperation of fixed blades 50 and drive blades 51. A drive air inlet 54 is located at the top of the sweeping rod cylinder 5, connected to the auxiliary air outlet of the electromagnetic drive system via a branch pipe 32 equipped with a pressure sensor. The pressure sensor is electrically connected to the PLC control system, providing real-time feedback of the cavity pressure data to ensure the drive force matches the fabric characteristics. A pressure relief exhaust port 55 is located at the bottom of the sweeping rod cylinder 5, corresponding to the bottom of the guide cavity, with a one-way pressure relief valve to ensure unidirectional gas discharge.

[0047] In specific implementation, the fixed blade 50 is a circular metal sheet made of stainless steel. Its outer diameter is adapted to the inner wall of the sweeper cylinder 5. It is sealed to the side wall of the cylinder by circumferential welding and fixedly installed at half the axial position of the cylinder. It divides the inside of the cylinder into two independent spaces, the upper one being the drive chamber for power output and the lower one being the guide chamber for motion guidance. The fixed blade 50 has a bearing mounting hole in the center for mounting the support bearing of the hollow fixed rotating shaft 52.

[0048] In practice, the drive blade 51 is also made of stainless steel. Its outer contour slides against the inner wall of the sweeper cylinder 5, and its edge is embedded with a high-temperature and wear-resistant fluororubber sealing strip to form a sliding seal, ensuring that the internal pressure of the drive cavity does not leak. It can efficiently convert gas pressure into rotational torque around the hollow fixed shaft 52. The drive blade 51 and the fixed blade 50 are arranged coaxially to form the sealing boundary of the drive cavity. The torsion spring in the reset assembly is fitted on the outside of the hollow fixed shaft 52. One end of the torsion spring is fixed to the side of the drive blade 51 by a buckle, and the other end is anchored to the protrusion on the side wall of the cylinder. When the drive blade 51 rotates, the torsion spring is twisted and stores force. When the pressure is released, the blade 51 is driven to reset quickly through the elastic restoring force.

[0049] The hollow fixed rotating shaft 52 has a stepped hollow shaft structure. One end is rotatably mounted in the central hole of the fixed blade 50 via a bearing, and the other end passes through the side wall of the sweeping rod cylinder 5 and extends to the outside. A rotating sealing sleeve is provided at the penetration point between the shaft and the side wall of the cylinder. A vent hole is provided on the side wall of the rotating shaft corresponding to the position of the drive cavity to introduce the high-pressure gas in the drive cavity into the internal channel of the rotating shaft, providing extension and retraction power for the telescopic drive assembly. The axial channel of the rotating shaft is connected to the radial vent hole 420 to form a complete air conduction path.

[0050] In practical implementation, the telescopic drive assembly includes a hollow guide rod 56, a hollow telescopic rod 57, and a pre-tensioned compression spring. The hollow guide rod 56 has an L-shaped structure and is made of lightweight, high-strength aluminum alloy. Its horizontal section is fixedly connected to the extended end of the hollow fixed rotating shaft 52, and its internal channel is fully connected to the axial channel of the rotating shaft to ensure smooth gas flow. The vertical section of the hollow guide rod 56 is cylindrical. The hollow telescopic rod 57 also has an L-shaped structure and is made of the same material as the hollow guide rod 56. Its vertical section is fitted onto the outside of the vertical section of the hollow guide rod 56 with a clearance fit. The hollow telescopic rod 57 has an annular limiting platform inside. A pre-compression spring is installed between the hollow telescopic rod 57 and the hollow guide rod 56. One end of the spring abuts against the limiting platform inside the hollow telescopic rod 57, and the other end is fixed to the end step of the vertical section of the hollow guide rod 56. Under normal conditions, the spring is in a pre-compressed state, pulling the hollow telescopic rod 57 towards the hollow guide rod 56, thus placing the sweeping rod 53 in a retracted, ready-to-go position. The horizontal section of the hollow telescopic rod 57 extends perpendicular to the fabric conveying direction, forming a rigid frame for the sweeping rod 53. Its length is slightly greater than the maximum width of the processed fabric, ensuring that the sweeping range completely covers the fabric width.

[0051] In practice, the sweeping bar 53 consists of a rigid frame and a flexible actuator. The flexible actuator is a long strip of flexible rubber that is fixed to the bottom of the rigid frame with bolts. The rubber strip is made of silicone and has fine anti-slip texture on its surface. It has sufficient clamping force to smooth out wrinkles and avoids scratching the surface of sensitive fabrics. At the same time, its high coefficient of friction can drive the fabric to the subsequent conveying roller 2 during the sweeping process, so as to achieve the simultaneous flattening and conveying.

[0052] In practice, the center distance between the secondary flattening mechanism and the primary flattening mechanism is set to 1.5 to 2 times the rotation diameter of the primary mechanism push rod 45. This distance ensures that after the fabric is lifted and initially flattened by the primary push rod 45, it can immediately enter the working range of the secondary mechanism, avoiding new wrinkles caused by gravity sagging in the middle section, and also provides sufficient movement space for the sweeping action of the secondary mechanism. During operation, the primary mechanism push rod 45 rotates clockwise, lifting the fabric upwards and initially ironing it with hot air; the secondary mechanism sweeping rod rotates counterclockwise with the drive blade 51, pressing the fabric downwards. When the fabric is lifted by the primary push rod 45 and forms a slight arc, the secondary sweeping rod precisely applies downward pressure to the fabric surface, firmly pressing the fabric onto the primary push rod 45, ensuring full contact between the two, thus offsetting the influence of airflow disturbance and enhancing the wrinkle-relieving effect through pressure.

[0053] The specific working process of the secondary leveling mechanism is as follows: When the high-pressure gas from the electromagnetic drive system enters the drive chamber of the sweeping rod cylinder 5 through the branch pipe 32 and the drive air inlet 54, the gas pressure first acts on the upper surface of the drive blade 51. In the initial stage, the pressure overcomes the preload of the torsion spring and the elastic force of the compression spring in the telescopic drive assembly, pushing the drive blade 51 to rotate counterclockwise around the hollow fixed rotating shaft 52. At the same time, the hollow fixed rotating shaft 52 rotates synchronously with the drive blade 51. During this process, some of the high-pressure gas in the drive chamber enters the axial channel of the rotating shaft through the radial ventilation hole 420 on the side wall of the hollow fixed rotating shaft 52, then flows through the internal channel of the hollow guide rod 56, and finally enters the gap between the hollow telescopic rod 57 and the guide rod. The gas pressure pushes the telescopic rod to extend outward along the vertical section of the guide rod, driving the sweeping rod 53 to move downward synchronously and gradually approach the fabric surface.

[0054] As the gas pressure continues to increase, the rotation angle of the drive blade 51 continuously increases. After the sweeping bar 53 extends to its final position, the flexible rubber strip at its bottom completely adheres to the fabric surface, forming a stable pressing force. At this time, the sweeping bar sweeps in an arc along with the counterclockwise rotation of the drive blade 51. On the one hand, it thoroughly compacts and smooths the fine wrinkles caused by the elastic shrinkage of the fibers after the first stage of flattening. On the other hand, through the friction between the rubber strip and the fabric, it smoothly delivers the fabric to the subsequent conveying roller 2. During this process, the fabric is tightly pressed against the first-stage pusher 45. The full contact between the two not only avoids the shaking caused by the airflow but also allows the hot airflow effect of the first-stage pusher 45 to continue, further softening the fibers and eliminating internal stress.

[0055] When the drive blade 51 rotates to the lower semicircular position of the drive chamber of the sweeping rod cylinder 5, the drive chamber is connected to the outside through the pressure relief port 55 at the bottom of the cylinder. The high-pressure gas in the chamber is quickly discharged through the one-way pressure relief valve, and the pressure in the chamber drops sharply. At this time, the compression spring in the telescopic drive assembly returns to the pre-compression state, pulling the hollow telescopic rod 57 back towards the guide rod. The sweeping rod 53 moves upward synchronously, detaching from the fabric surface to avoid stretching deformation caused by friction with the fabric during the reset process. At the same time, the torsion spring releases the stored elastic potential energy, driving the drive blade 51 to rotate in the opposite direction around the hollow fixed rotating shaft 52 until it returns to the initial position. The hollow fixed rotating shaft 52, the guide rod, and the telescopic rod also reset, waiting for the next high-pressure gas input to achieve uninterrupted fine-tuning and smoothing of the continuously conveyed fabric.

[0056] Example 3 The three-stage paving mechanism includes an infrared detection device 6, a signal processing module, an air jet device 60, and a control valve assembly. The infrared detection device 6 includes an infrared transmitter, an infrared receiver, and a mounting bracket. The mounting bracket is fixed inside the processing housing 1 and located behind the sweeping rod assembly. The infrared transmitter and infrared receiver are symmetrically mounted on the mounting bracket to form a through-beam detection structure, and the detection range covers the entire width and thickness direction of the fabric.

[0057] The signal processing module includes a signal amplifier, an A / D converter, and a PLC controller. The output of the infrared receiver is electrically connected to the signal amplifier, the output of the signal amplifier is electrically connected to the A / D converter, and the output of the A / D converter is electrically connected to the PLC controller. This module is used to convert infrared detection signals into digital signals to identify wrinkles and overlapping areas on the fabric surface.

[0058] The jetting device 60 includes a main air duct, zone branch pipes, jet nozzles, and a mounting beam. The main air duct is connected to the outlet pipe of the electromagnetic drive system. The zone branch pipes are evenly arranged along the length of the mounting beam, and each zone branch pipe is connected to the main air duct. Each zone branch pipe is equipped with an independent control valve, which is electrically connected to a PLC controller to achieve independent zone control. The jet nozzles are installed at the bottom of the zone branch pipes, facing the fabric surface. The jetting angle of the nozzles can be adjusted by adjusting the bracket to ensure that the airflow can accurately act on the wrinkled area.

[0059] In practice, the infrared detection device 6 is installed at a height 5-10cm above the fabric surface to ensure the accuracy of the detection signal and avoid false detections caused by fabric vibration. The detection frequencies of the infrared transmitter and receiver are matched with the fabric conveying speed to ensure real-time capture of changes in the fabric surface condition.

[0060] The mounting beam of the jetting device 60 is parallel to the width direction of the processing box 1. The number of zoned branch pipes is determined according to the fabric width, generally one zoned branch pipe is set every 10cm to ensure that the detected wrinkled areas can be accurately positioned for jetting. The control valve group uses electromagnetic valves with a response time of no more than 10ms to ensure that the jetting channel can be opened or closed in a timely manner, avoiding energy waste caused by ineffective jetting.

[0061] When the fabric passes through the infrared detection device 6, the infrared light emitted by the infrared emitter passes through the fabric and is received by the infrared receiver. If there are wrinkles or overlaps on the fabric surface, the amount of infrared light transmitted will change. The infrared receiver converts the changing light signal into an electrical signal, which is then amplified by a signal amplifier and converted into a digital signal by an A / D converter and transmitted to the PLC controller. The PLC controller analyzes and processes the signal to determine the specific location and area of ​​the wrinkles. Then, it sends an opening signal to the control valve on the corresponding branch pipe. The control valve opens, and high-pressure gas is precisely injected into the wrinkled area through the jet nozzle. The impact force of the airflow smooths out the wrinkles, achieving three-level precise smoothing.

[0062] Once the infrared detection device 6 detects that the fabric surface is flat, the PLC controller sends a shut-off signal to the control valve to stop the air jet, ensuring that the air jet operation is only performed when needed, thereby improving energy efficiency.

[0063] Example 4 The heating and shaping zone is equipped with a zoned precision temperature control system, including the heating and shaping zone itself, three sets of heating devices 7, temperature detection sensors, heat absorption cover assembly 73, and temperature control module. The heating and shaping zone is located in the middle of the processing chamber 1 and is divided into three independent temperature zones along the fabric conveying direction: a preheating section 70, a main shaping section 71, and a functional curing section 72. Each temperature zone is separated by a heat insulation plate made of high-temperature resistant insulation material to prevent heat transfer between temperature zones and ensure the temperature independence of each zone.

[0064] In practical implementation, the heating device 7 includes an eddy current converter, heating wires, and a mounting frame. Three sets of heating devices 7 are installed inside the three temperature zones respectively. The mounting frame is fixed to the side wall of the processing chamber 1. The heating wires are evenly distributed on the mounting frame, parallel to the fabric conveying direction. The input end of the heating wire is electrically connected to the eddy current converter, which converts electrical energy into heat energy, releasing heat through the heating wire to achieve temperature zone heating. The power of the heating wire in each temperature zone can be independently adjusted. The preheating section 70 has a lower power, the main shaping section 71 has the highest power, and the functional curing section 72 has a power between the two, adapting to the requirements of the temperature curve.

[0065] In practice, the temperature detection sensor is an infrared temperature sensor. Multiple sensors are installed inside each temperature zone, evenly distributed on the top and sides of the temperature zone. The detection end of the sensor faces the fabric surface to detect the temperature of the fabric and the temperature inside the temperature zone in real time. The output end of the sensor is electrically connected to the temperature control module to transmit the temperature signal to the controller.

[0066] In specific implementation, the heat absorption hood assembly 73 includes a heat absorption hood body, an air pump, and a connecting pipe. The heat absorption hood body has an arc-shaped structure and is installed at the bottom of each temperature zone, communicating with the interior of the temperature zone. The interior of the heat absorption hood body is equipped with heat-conducting fins to enhance heat absorption efficiency. The air pump is installed outside the processing box 1 and is connected to the heat absorption hood body through the connecting pipe. The pipe is equipped with an electromagnetic valve, which is electrically connected to the temperature control module to control the opening and closing of the pipe. The other end of the connecting pipe is connected to the heat energy recovery device to transport the absorbed excess heat to the recovery device.

[0067] In specific implementation, the temperature control module includes a PLC controller, a temperature setting unit, and a power adjustment unit. The temperature setting unit is used to preset the temperature curves (heating rate, holding temperature, and cooling rate) of three temperature zones. The power adjustment unit is electrically connected to the eddy current converter of the heating device 7 and adjusts the input power of the heating wire according to the signal of the temperature detection sensor. The PLC controller is electrically connected to the air pump and the solenoid valve to control the start and stop of the heat absorption hood assembly 73.

[0068] In practice, the heating devices 7 of the three temperature zones are arranged sequentially along the fabric conveying direction, with the preheating section 70 at the front, the main shaping section 71 in the middle, and the functional curing section 72 at the rear. Fabric channels are provided on the heat insulation plates between the temperature zones, with the channel width slightly larger than the fabric width to ensure smooth fabric passage while reducing heat leakage. The temperature detection sensors are installed away from the direct radiation range of the heating devices 7 to avoid detection errors.

[0069] In practice, when the fabric enters the heating and setting zone, it first enters the preheating section 70. The temperature control module activates the heating device 7 in the preheating section 70, and the heating wire releases heat to gradually raise the temperature of the preheating zone to the preset preheating temperature (generally 80-120℃). The heating rate is controlled at 5-10℃ / min by the power adjustment unit to avoid sudden temperature rises that could damage the fabric fibers. The temperature detection sensor monitors the temperature of the preheating section 70 in real time. When the temperature reaches the preset value, the power adjustment unit adjusts the power of the heating wire to maintain a constant temperature.

[0070] In practice, after passing through the preheating section 70, the fabric enters the main setting section 71. The heating device 7 of the main setting section 71 is fully powered, rapidly raising the temperature of the set area to the preset main setting temperature (generally 150-200℃). This temperature is the optimal setting temperature for the intelligent temperature-regulating fabric, ensuring the fabric's dimensional stability and functional characteristics. The temperature control module adjusts the power of the heating wire in real time based on the signal from the temperature detection sensor, keeping the temperature fluctuation range of the main setting section 71 within ±2℃ to prevent excessively high temperatures from causing the intelligent temperature-regulating material to malfunction.

[0071] In practice, after the fabric leaves the main shaping section 71, it enters the functional curing section 72. The temperature control module controls the heating device 7 in this area to gradually reduce its power, so that the temperature in the temperature zone drops to 100-120℃ at a preset cooling rate (3-8℃ / min), thus heat-preserving and curing the fabric and ensuring the stable and long-lasting functional characteristics of the intelligent temperature-regulating material. The temperature detection sensor monitors the cooling process in real time. If the cooling rate is too fast, the power adjustment unit appropriately increases the power of the heating wire; if the cooling rate is too slow, the power is reduced to ensure that the temperature curve meets the preset requirements.

[0072] In practice, when the temperature sensor detects that the temperature of a certain temperature zone exceeds the preset upper limit, the temperature control module immediately sends a start signal to the heat absorption shroud assembly 73 of that temperature zone. The solenoid valve opens, the air pump starts, and the heat absorption shroud absorbs excess heat from inside the temperature zone. The heat-conducting fins increase the heat absorption area and improve heat absorption efficiency. The absorbed heat is transported to the heat recovery unit through connecting pipes for energy conversion and heat recovery. When the temperature of the temperature zone drops to the preset range, the temperature control module controls the air pump to stop working, the solenoid valve to close, and the heat absorption shroud assembly 73 stops absorbing heat.

[0073] The heat recovery system includes a heat recovery unit, an energy conversion module, an energy storage unit, and power supply pipelines. The heat recovery unit adopts a waste heat boiler structure and has internal heat exchange tubes. One end of the heat exchange tubes is connected to the connecting pipe of the heat absorption hood assembly 73, and the other end is connected to the exhaust pipe, which extends to the outside of the processing chamber 1 to discharge the low-temperature gas after heat exchange. The heat exchange tubes are equipped with an insulation layer to reduce heat loss, and the inside of the recovery unit is filled with a heat-conducting medium to enhance heat exchange efficiency.

[0074] The energy conversion module includes a thermoelectric generator and a rectifier. The thermoelectric generator is installed on the outer wall of the heat exchange tube of the heat recovery unit and generates electricity by utilizing the temperature difference between the high-temperature gas inside the heat exchange tube and the external environment. The rectifier is electrically connected to the thermoelectric generator and converts the generated alternating current into direct current to charge the energy storage unit and power the equipment.

[0075] The energy storage unit uses a lithium battery pack, installed outside the processing housing 1, and electrically connected to the rectifier to store converted electrical energy. The energy storage unit is equipped with a charging protection module to prevent overcharging and battery damage. The power supply system includes power lines and an inverter. The inverter is electrically connected to the energy storage unit, converting DC power to AC power, which is then transmitted through the power lines to the eddy current converter and other electrical components of the equipment (such as the PLC controller and detection devices), thus achieving energy recycling.

[0076] The heat exchange tubes of the heat recovery unit are sealed to the connecting pipes of the heat absorption hood assembly 73 to ensure that high-temperature gas will not leak. A temperature sensor is installed on the pipe to detect the temperature of the gas entering the recovery unit in real time. When the temperature is below 50°C, the PLC controller closes the solenoid valve of the pipe to prevent low-temperature gas from entering the recovery unit and affecting the recovery efficiency.

[0077] When the heat absorption hood assembly 73 transfers excess heat to the heat recovery unit, the high-temperature gas flows through the heat exchange tubes and exchanges heat with the heat-conducting medium outside the tubes. The temperature of the heat-conducting medium rises, creating a temperature difference with the external environment. The thermoelectric generator produces electricity under the influence of this temperature difference. The generated electricity is converted into direct current by a rectifier. Part of it is directly transmitted to the eddy current converter through the power line to power the heating device 7; the other part is sent to the energy storage unit for storage. When the equipment is initially started up or when the amount of heat recovered is insufficient, the energy storage unit releases electrical energy to ensure stable operation of the equipment.

[0078] A voltage stabilizer is installed on the power supply pipeline to regulate the output voltage and ensure that the power supply voltage meets the equipment's power requirements (220V / 380V). The energy conversion module is electrically connected to the PLC controller to monitor the amount of electricity generated and the power of the energy storage unit in real time. When the energy storage unit is fully charged, the PLC controller controls the rectifier to stop charging to avoid overcharging. When the power is lower than a preset threshold, the energy stored in the energy storage unit is used first, and the remaining part is supplemented by the external power grid.

[0079] The overall workflow of a textile fabric setting method based on an intelligent temperature-regulating textile fabric production setting equipment is as follows: First, after the operator turns on the main power of the equipment, the processing parameters are input through the PLC, including the stepless speed adjustment of the conveyor roller 2 set according to the fabric material, the gas pressure of the first-level flattening mechanism, the clamping force threshold of the second-level flattening mechanism, the air jet response sensitivity of the third-level zone, and the temperature curves of the three temperature zones of the heating and shaping zone (preheating section 7080-120℃, main shaping section 71150-200℃, functional curing section 72100-120℃), heating rate (5-10℃ / min), cooling rate (3-8℃ / min), etc. Finally, the zone temperature control system starts preheating, the heating device 7 heats up through the eddy current converter, the temperature detection sensor provides real-time feedback, the temperature control module dynamically adjusts the power to make the three temperature zones reach the preset state, and at the same time the electromagnetic drive system starts the no-load circulation to discharge the residual gas in the pipeline.

[0080] After the start-up preparation is completed, the feeding and continuous conveying stage begins. The operator fixes the roll of fabric to be processed in the feeding area. The starting end of the fabric passes through the guide roller and adheres to the surface of the conveying roller 2. After the conveying system is started, the stepper motor drives multiple conveying rollers 2 to operate synchronously at a preset speed. The conveying is continuous and stable along the route of the feeding area, the flattening treatment area, the heating and shaping area, and the discharge area. The PLC control system monitors the conveying speed in real time and fine-tunes the speed according to the feedback signals from subsequent processing stages to ensure that the conveying and each processing action are coordinated and matched.

[0081] After the fabric enters the flattening treatment area, it undergoes three stages of flattening. During the first stage, the electromagnetic drive system delivers high-pressure gas to the push rod cylinder 4. The gas enters the closed air chamber formed by the flap door and blades. Once the pressure reaches a preset threshold, it pushes the blades to rotate clockwise, causing the L-shaped push rod 45 to move in a circular motion. The horizontal section of the push rod 45 lifts the fabric, smoothing large wrinkles. Simultaneously, some of the high-pressure gas is ejected through the air passage from the jet nozzle 451 to soften the fibers and smooth fine wrinkles. After the blades rotate and squeeze the flap door to open and release pressure, they reset under the attraction of the magnet and the limit of the ratchet mechanism 43. The flap door also closes with the torsion spring and enters the next cycle. During the second stage, the high-pressure gas enters the drive chamber of the sweeping rod cylinder 5. The drive blade 51 is rotated counterclockwise and the torsion spring stores energy. At the same time, the gas-driven telescopic component extends the sweeping rod 53, and the flexible rubber strip adheres to the fabric. As the drive blade 51 sweeps along the arc, it compacts the fine wrinkles and delivers the fabric. At this time, it works with the first-stage push rod 45 to press the fabric and enhance its effect. When the drive blade 51 rotates to the pressure relief port, the gas is discharged, and the compression spring and torsion spring drive the component to reset. During the three-stage flattening, the infrared detection device 6 scans the fabric. The change in infrared light transmittance caused by the wrinkled area is transmitted to the PLC after signal processing. The PLC controls the corresponding zone solenoid valve to open, and high-pressure gas is precisely sprayed through the nozzle to smooth the wrinkles. After the fabric is detected to be flat, the valve closes.

[0082] The laid-out fabric enters the heating and setting zone for precise temperature control in different zones: First, it enters the preheating section 70, where the heating device 7 operates at low power, raising the temperature to 80-120℃ at a rate of 5-10℃ / min. Temperature sensors provide real-time feedback, and the temperature control module fine-tunes the power to maintain a constant temperature. Next, it enters the main setting section 71, where the heating device 7 operates at full power, rapidly raising the temperature to 150-200℃. The temperature control module precisely adjusts the power to ensure that temperature fluctuations are controlled within ±2℃. If the temperature exceeds the upper limit, the heat absorption cover assembly 73 is activated to absorb excess heat. Then, it enters the functional curing section 72, where the heating device 7 gradually reduces its power, lowering the temperature to 100-120℃ at a rate of 3-8℃ / min. Sensors monitor the cooling process, and adjust the power to correct any abnormalities. The high-temperature gas absorbed by the heat absorption hood is transported to the heat recovery unit through pipelines. After heat exchange with the heat transfer medium through heat exchange tubes, the thermoelectric generator uses the temperature difference to generate electricity. After conversion by the rectifier, part of the electricity is directly supplied to the electrical components of the equipment, and the other part is stored in the lithium battery pack. When the energy storage unit is low on power, it releases the electricity first, and the remaining part is supplemented by the external power grid, thus realizing the recycling of energy.

A method for setting and processing textile fabrics based on a setting and processing equipment for intelligent temperature-regulating textile fabric production according to any one of claims 1-8, characterized in that, Includes the following steps: S1. Input the fabric to be processed into the processing box (1) and convey it along the set path by the conveyor roller (2); S2. The push rod (45) of the first-level flattening mechanism performs lifting and circular motion to perform preliminary mechanical flattening and wrinkle removal on the fabric, while the hot airflow ejected by the push rod (45) softens the fibers. S3. The sweeping bar (53) of the secondary flattening mechanism performs downward pressure and arc sweeping motion, pressing the fabric tightly against the surface of the push bar (45) to enhance the wrinkle removal effect, and using its friction to assist in delivering the fabric; S4. The three-stage flattening mechanism detects the surface condition of the fabric through an infrared detection device (6) and controls the air jet device (60) to precisely air jet flatten the wrinkled areas; S5. The fabric that has been laid flat is transported to the zoned temperature control system, so that it passes through the preheating zone (70), the main shaping zone (71) and the functional curing zone (72) in sequence for gradient heating and shaping; S6. Output the shaped fabric.

10. The textile fabric finishing process according to claim 9, characterized in that, Step S3 specifically includes the following steps: S31. When the push rod (45) lifts the fabric upward and forms a supporting curved surface, the sweep rod (53) moves downward simultaneously; S32. The sweeping bar (53) contacts the fabric and presses it against the lifting surface of the push bar (45); S33. The sweeping bar (53) sweeps in an arc with the rotation of the drive blade (51) while in a clamped state, smoothing the material and delivering it forward by means of friction. S34. After delivery is completed, the sweeping bar (53) retracts upward and resets, and the push bar (45) resets simultaneously.
