Description

Technical Field

[0001] This invention relates to the field of fashion processing, and in particular to a hydraulic steam garment bonding device and its method for use in fashion design. Background Technology

[0002] In fashion design and production processes, it is often necessary to heat-press and bond multiple layers of square fabric for shaping. Some equipment suitable for this scenario has been disclosed in the existing technology.

[0003] For example, CN219613150U discloses a fabric bonding device for clothing design, which achieves heat-press bonding through upper and lower pressure plates and a heating plate. However, this solution has shortcomings in actual operation: its method of fixing the fabric to be bonded is relatively simple, relying solely on the opening and closing of the pressure plates for positioning. For square fashion fabrics that need to be laid flat, there is a lack of effective flattening and tensioning mechanisms, making it easy for wrinkles or positional shifts to occur when the fabric is placed. If the fabric cannot be guaranteed to be in a uniform, taut, and wrinkle-free state before heat pressing, it will directly affect the uniformity and bonding strength of the adhesive layer, leading to quality problems such as bubbles and delamination on the surface of the finished product, which is particularly difficult to meet the requirements of fashion design with high precision requirements. For example, a cooling and shaping device for a hot melt bonding machine, disclosed in announcement number CN201197395Y, utilizes circulating cooling water to cool the upper pressure plate, thereby accelerating the shaping of the bonded fabric. However, it relies primarily on a single liquid circulation channel, resulting in limited cooling efficiency. If the bonded fabric does not receive rapid and sufficient forced cooling before being removed from the pressure plate, it is highly susceptible to localized deformation during natural cooling and shrinkage, damaging the newly formed bonded structure. This is especially true for large square sheets, where the difference in cooling rates between the edges and the center exacerbates internal stress and warping, leading to poor product shaping and ultimately affecting the dimensional stability and smoothness of the garment components. Summary of the Invention

[0004] To overcome the above shortcomings, the present invention provides a hydraulic steam garment bonding device and method for fashion design, aiming to improve the problem of poor bonding effect of square garment sheets affecting the quality of fashion.

[0005] This invention is implemented as follows: This invention provides a hydraulic steam garment bonding device for fashion design, comprising a vertical frame, on which a lower pressure plate and an upper pressure plate are arranged for pressing square garment sheets, and further comprising: The shaping section includes four sets of movable supports, each set of movable supports is equipped with a Y-shaped lifting support, and each set of Y-shaped lifting supports is equipped with a fixture for clamping the right-angle end of the fashion square sheet. The fixture includes two symmetrically distributed T-shaped clamping members, and each of the two T-shaped clamping members is equipped with a telescopic capsule. The two telescopic capsules are filled with cold air to flexibly clamp the right-angle end of the fashion square sheet. A heating section is disposed in a lower pressure plate and includes an electric heating wire built into the lower pressure plate. A heat-conducting mesh is mounted on the lower pressure plate and laid on the electric heating wire. The heat dissipation section is disposed on the upper pressure plate and includes a heat-conducting pipe column fixedly installed on the upper pressure plate. The upper pressure plate has a heat dissipation cavity, and the heat-conducting pipe column has a cooling cavity and a recovery cavity. Each cavity is used for circulating coolant. The upper pressure plate uses coolant to cool down the bonded fashion square sheet until it solidifies and sets.

[0006] Preferably, the vertical frame includes a four-legged base, on which four guide columns are fixedly mounted, and a fixed ceiling is fixedly connected to the four guide columns.

[0007] Preferably, the lower pressure plate is fixedly mounted on the four-legged base, and the upper pressure plate is longitudinally slidably mounted on the four guide columns, with the upper pressure plate corresponding to the lower pressure plate vertically.

[0008] Preferably, the four sets of movable supports are equidistantly distributed around the lower pressure plate, and the four sets of movable supports adjust the horizontal position of the fixer by radial movement to tighten the square sheet.

[0009] Preferably, the cold gas is helium, and the T-shaped clamp is equipped with a helium mass spectrometer leak detector for detecting whether helium is leaking.

[0010] Preferably, the heating part further includes a square annular groove formed on the lower pressure plate, and the heat-conducting mesh is fitted onto the lower pressure plate through the square annular groove.

[0011] Preferably, the lower pressure plate and the square annular groove are provided with heat-conducting elongated holes.

[0012] Preferably, the fixed ceiling is provided with a traction part for pulling the upper pressure plate vertically up and down along the guide column.

[0013] Preferably, the heat-conducting tube column is further provided with an air-cooling cavity, and a curved cold air duct extending through the air-cooling cavity extends from the air-cooling cavity.

[0014] The above-mentioned method of using a hydraulic steam garment bonding device for fashion design includes the following steps: Step S1: Place the square fashion sheet to be bonded on the heat-conducting mesh. Four movable supports, equidistant from each other around the lower pressure plate, adjust the horizontal position of their respective upper retainers by radial movement. Each retainer has a telescopic capsule in each of its two T-shaped clamping parts. At the same time, cryogenic helium is injected into the telescopic capsule to make it fully expand, thereby forming a flexible and uniform clamping force on the four right-angled ends of the square fashion sheet. Meanwhile, a helium mass spectrometer leak detector will detect whether there is a helium leak in real time to ensure the sealing and reliability of the clamping system. In step S2, after the retainer clamps the right-angle end of the fashion square sheet, the Y-shaped lifting bracket can drive the retainer to make a fine adjustment in the vertical direction, while the moving bracket continues to move slowly outward in the radial direction. The two work together to apply radial tension to the fashion square sheet, so that it is laid flat and taut on the upper surface of the lower pressure plate, providing a wrinkle-free flat state for subsequent hot pressing and bonding. In step S3, the upper pressure plate, driven by the traction unit, slides vertically downward along the four guide columns and closes with the lower pressure plate. At this time, the heating unit is activated. When the electric heating wire is energized, the heat is conducted to the heat-conducting mesh through the heat-conducting elongated holes. The fashion square sheet comes into direct contact with the heat-conducting mesh, and the heat is evenly transferred to the fashion square sheet. At the same time, the upper pressure plate applies pressure to complete the hot-press bonding. Step S4: After bonding is complete, to prevent the fabric from deforming or delaminating during natural cooling, immediately activate the cooling unit: The coolant enters the heat dissipation cavity inside the upper pressure plate from the outside, then flows into the cooling cavity in the heat-conducting pipe column, and finally flows out through the recovery cavity. The upper pressure plate quickly absorbs the heat of the bonded fabric through the coolant and forces it to cool down, so that the bonded layer can be quickly solidified and shaped. In addition, the air-cooled cavity and the curved air duct can help to dissipate heat and improve cooling efficiency. Step S5: After the shaping is completed, the traction unit drives the upper pressure plate to rise and reset. At this time, the low-temperature helium gas in the telescopic capsule is discharged or recovered, the T-shaped clamping part loses its support, and the right-angle end of the fabric is automatically released. The moving bracket and the Y-shaped lifting bracket are reset to their initial positions, and the glued and shaped fashion square sheet can be taken out from the heat-conducting mesh.

[0015] The beneficial effects of this invention are: 1. Unlike existing technologies that rely solely on pressure plates to fix fabric, this invention utilizes four sets of movable supports, a Y-shaped lifting support, and a fixing device that work together around the lower pressure plate. In particular, the fixing device employs a telescopic capsule that can be inflated with cold air, which can flexibly and evenly clamp the four corners of the fabric, avoiding damage to the fabric from rigid clamps. Subsequently, through the radial movement of the movable supports and the longitudinal fine adjustment of the Y-shaped lifting support, a controllable radial tension is actively applied to the fabric, laying it flat and taut on the surface of the lower pressure plate. This helps to avoid problems such as uneven bonding, bubbles, and delamination caused by fabric wrinkles and displacement, thereby improving bonding quality and yield.

[0016] 2. Compared to traditional simple water cooling circulation, this invention constructs a composite cooling system within the upper pressure plate, including a heat dissipation chamber, a cooling chamber, a recovery chamber, and an air-cooling chamber. It absorbs heat through coolant circulation and introduces air-cooling chambers and curved air ducts to assist in heat dissipation of the high-temperature coolant, forming a highly efficient heat exchange structure with liquid cooling as the main component and air cooling as the auxiliary component. This structure can quickly remove the heat from the bonded fabric, forcing it to cool and solidify rapidly under pressure, effectively preventing shrinkage, deformation, and warping caused by uneven natural cooling, and ensuring the long-term stability of the dimensional accuracy and appearance of the fashion square sheet.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of 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 of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example Reference Figures 1-9 A hydraulic steam garment bonding device for fashion design includes a vertical frame 1, on which a lower pressure plate 2 and an upper pressure plate 3 for pressing square garment sheets are provided. It also includes a shaping section 4, a heating section 5, and a cooling section 7, forming a closed-loop working system that completes the entire process from sheet pretreatment, hot pressing and bonding to cooling and shaping.

[0022] Reference Figure 1 and Figure 2The vertical frame 1 includes a four-legged base 11, which serves as the foundation platform for the entire machine. Shock-absorbing pads can be pre-embedded in its four support points to isolate external vibrations from interfering with the precision pressing process. Four guide columns 12 are fixedly mounted on the four-legged base 11, using a two-end fixed support method. The upper ends are securely connected to the fixed ceiling 13 via locking nuts. This not only provides a high-precision longitudinal motion reference guide for the upper pressure plate 3 but also evenly transmits the reverse force generated during the pressing process to the four-legged base 11 through the four guide columns 12, forming a symmetrical closed load-bearing frame to ensure the structural rigidity and long-term stability of the equipment under maximum pressing force. The fixed ceiling 13 is fixedly connected to the four guide columns 12, integrating the top positioning and drive installation functions of the equipment.

[0023] in: Reference Figure 4 The shaping part 4 includes a traction square plate 41 rotatably mounted on a four-legged base 11. A crossed roller bearing or slewing bearing is disposed between the traction square plate 41 and the four-legged base 11 to withstand the overturning moment generated during radial tension. A traction link 43 is connected to the end pin of the traction square plate 41. The power source of the traction square plate 41 can be a stepper motor or a servo motor, and precise angular rotation is achieved through gear meshing or synchronous belt drive. When the traction square plate 41 is rotated in a controlled manner, the traction link 43 connected to its end pin swings accordingly, converting the rotational motion into synchronous radial linear motion of four sets of moving supports 42 along the right-angle end guide rail of the four-legged base 11.

[0024] The four right-angled ends of the four-legged base 11 are each provided with a movable bracket 42. The movable bracket 42 is connected to the traction link 43 by a pin. The traction plate 41 and the traction link 43 ensure that the four fixings 45 can move toward the center or expand outward with the same speed and displacement, thereby applying a balanced radial tension to the four right-angled ends of the fashion square sheet.

[0025] One end of the traction link 43 is pinned to the eccentric shaft of the traction disk 41 via a spherical bearing, and the other end is connected to the drive pin of the movable bracket 42 via a fisheye connector, thereby forming four sets of independent and linked crank-slider mechanisms.

[0026] Each of the four sets of movable supports 42 is longitudinally equipped with a Y-shaped lifting support 44. The longitudinal movement of the Y-shaped lifting support 44 on the movable support 42 can be driven by a built-in micro electric push rod or pneumatic slide table, achieving micron-level vertical height adjustment to adapt to the clamping requirements of fabric sheets of different thicknesses. Combined with radial tension, this ensures that the fabric sheet, while reaching the predetermined tension, fits precisely against the upper surface of the lower pressure plate 2, completely eliminating interlayer gaps and wrinkles. Each of the four sets of Y-shaped lifting supports 44 is equipped with a retainer 45 for clamping the right-angled ends of the square fabric sheet during fashion.

[0027] To further explain, each set of movable brackets 42 has an independent vertical precision ball screw module built in, which drives the Y-type lifting bracket 44 to make micro-adjustments in the vertical direction. This micro-adjustment action is performed by a micro servo motor equipped with a brake function, which can maintain the position when the power is off, so as to adapt to fashion square sheets of different weights and thicknesses, ensuring that while applying radial tension, the bottom surface of the sheet can accurately form a coplanar fit with the upper surface of the lower pressure plate 2, eliminating interlayer gaps and initial wrinkles.

[0028] Furthermore, the retainer 45 is an end effector that achieves non-destructive clamping and tension transmission. It includes a ball screw 451 rotatably mounted on a Y-shaped lifting bracket 44. Inside the retainer 45, the rotation of the ball screw 451 can be driven by a micro motor. A movable nut slider 452 adapted to and connected to the ball screw 451 is slidably mounted on the Y-shaped lifting bracket 44. By opening a guide hole in the Y-shaped lifting bracket 44, the movable nut slider 452 is slidably mounted to ensure that the movable nut slider 452 only performs linear reciprocating movement. The screw shaft of the ball screw 451 is connected to a micro DC brushless motor and a harmonic reducer assembly. When the motor rotates, it drives the movable nut slider 452 to move linearly along the precision guide hole opened in the Y-shaped lifting bracket 44.

[0029] At the front end of the Y-type lifting bracket 44, two symmetrically distributed T-shaped clamping members 453 are connected by a pin. A synchronous connecting rod 454 is pin-connected between the movable nut slider 452 and the T-shaped clamping members 453. When the movable nut slider 452 moves axially along the ball screw 451, the synchronous connecting rod 454 drives the two T-shaped clamping members 453 to perform symmetrical opening and closing movements around their pin connection point. During this process, the pressure-increasing protrusion 459 fixed on the synchronous connecting rod 454 regularly abuts against and compresses the elastic boss container 457.

[0030] Both T-shaped clamps 453 have a storage cavity 455, in which a telescopic capsule 456 is fixedly installed. A flexible boss container 457 for holding cold air is fixedly connected to the ball screw 451. The flexible boss container 457 integrates a one-way air inlet valve and a safety pressure relief valve. A corrugated hose 458 communicating with the telescopic capsule 456 is connected to the flexible boss container 457. The flexible boss container 457 is made of elastic memory material. When compressed, its internal volume decreases, and the inert cold air (helium) pre-filled inside is forced into the storage cavity 455 of the telescopic capsule 456 through the corrugated hose 458 to achieve inflation and expansion.

[0031] In some embodiments, a pressure-boosting protrusion 459 is fixedly installed on the synchronizing link 454, which movably abuts against the elastic boss container 457. It should be noted that when the ball screw 451 reverses and the T-shaped clamp 453 opens, the pressure-boosting protrusion 459 releases the pressure on the elastic boss container 457. The elastic boss container 457 recovers its deformation due to its own elasticity and generates negative pressure, drawing back the helium gas in the telescopic capsule 456, thereby achieving rapid degassing and release of the clamp.

[0032] The telescopic capsule 456 operates in a sealed helium environment. In conjunction with the helium mass spectrometer leak detector integrated on the T-shaped clamp 453, it can perform high-sensitivity real-time monitoring of helium leakage. Once the leakage rate is detected to exceed the set threshold, an alarm or shutdown is triggered to ensure the non-destructive clamping of high-value fashion fabric pieces throughout the entire process.

[0033] Two telescopic capsules 456 are filled with cold gas to flexibly clamp the right-angled ends of the square sheet. The entire gas path is a closed loop. In conjunction with a helium mass spectrometer leak detector integrated on each retainer 45, online leak monitoring is performed. Any trace helium leak (detection limit as low as 10⁻¹² Pa·m) can be detected. 3 All data (s) will be captured to ensure that high-value fashion items are processed without damage throughout the entire process.

[0034] To verify the technical superiority of the shaping section 4, a comparative experiment was conducted with existing conventional technical solutions: Experiment 1: Performance Comparison of Shaping Section 4 (Flexible Clamping vs. Active Flattening) Experimental subject: square fashion fabric made of wool and silk blend of the same size (20cm×20cm).

[0035] Evaluation indicators: clamping mark index (a score of surface fiber damage based on fabric angle microscopic image analysis, 0-10 points, the lower the score, the less damage) and surface flatness after flattening (the maximum peak-to-valley value PV value of the surface measured by a 3D optical profilometer, unit: mm).

[0036] It can be known that: While the mechanical steel claws in existing technology A can provide sufficient tension (flatness PV=0.48mm), they cause severe clamping damage to the fabric fibers (index 6.5), resulting in obvious indentations and even fraying. Although the negative pressure suction cups in existing technology B protect the fabric surface (index 1.5), the lack of a precise synchronous tension mechanism leads to inconsistent and unpredictable manual flattening results, ultimately resulting in the worst flatness (PV=0.72mm), which is insufficient to meet the requirements for precision bonding.

[0037] The shaping section 4 employs a flexible capsule clamping technology, which utilizes a uniformly expanded capsule to make flexible contact with the fabric surface, resulting in almost no damage; at the same time, the synchronous radial linkage mechanism provides highly consistent and precise tension, achieving the best flattening effect.

[0038] Reference Figure 3 and Figure 5 The heating element 5 is disposed in the lower pressure plate 2, aiming to achieve efficient and uniform three-dimensional heating. It includes a heat storage chamber 51 opened in the lower pressure plate 2, a square annular groove 52 opened on the lower pressure plate 2, an electric heating wire 53 built into the heat storage chamber 51 and installed on the lower pressure plate 2. Its heat output is PID regulated by a programmable logic controller according to a preset temperature curve. A heat-conducting mesh 55 is mounted on the lower pressure plate 2 and laid on the electric heating wire 53. The heat-conducting mesh 55 is mounted on the lower pressure plate 2 through the square annular groove 52.

[0039] Furthermore, the heat-conducting mesh 55 itself adopts a metal woven mesh with a high thermal conductivity. Its square annular groove 52 has a snap-fit ​​structure that facilitates quick replacement and cleaning, while also playing a role in uniform heat distribution and temperature equalization. The control system can receive thermocouple signals embedded in the heat-conducting mesh 55 in real time, and adjust the power of the electric heating wire 53 and the speed of the exhaust fan 54 through a PID algorithm to perform closed-loop control of the hot pressing temperature. The lower pressure plate 2 and the square annular groove 52 are provided with heat-conducting elongated holes 56 that connect to the heat storage chamber 51. The lower end of the lower pressure plate 2 is provided with an exhaust fan 54 that supplies clean air to the heat storage chamber 51. The exhaust fan 54 adopts a high-temperature resistant centrifugal fan, and its air inlet can be connected in series with a high-efficiency air filter to provide the system with dust-free air with a cleanliness level of ISO Class 5.

[0040] It is worth noting that after the clean air is fully heated by the electric heating wire 53 in the heat storage chamber 51, it forms a high-speed hot airflow through the densely distributed heat-conducting elongated holes 56, which evenly blows and penetrates the fiber gaps of the fashion square sheet laid on the heat-conducting mesh 55. This design combines traditional contact heat conduction with forced convection heat transfer, which helps to shorten the time for the central layer of the fabric to reach the bonding activation temperature.

[0041] The exhaust fan 54, in conjunction with the electric heating wire 53, controls the temperature of the square fabric sheet located on the heat-conducting mesh disk 55, achieving bonding between multiple layers of fabric sheets. The heat-conducting mesh disk 55 uses a copper-based woven mesh with high thermal conductivity anisotropy, which is tensioned and installed through square annular grooves 52. It not only acts as a heat-dissipating plate for contact heat transfer, but its mesh structure also provides a pathway for hot air penetration. Thin-film thermocouples embedded at multiple locations on the heat-conducting mesh disk 55 feed back real-time temperature signals to the PLC, forming a closed-loop control circuit to ensure temperature uniformity throughout the entire working area.

[0042] To verify the technical superiority of heating element 5, a comparative experiment was conducted with existing conventional technical solutions: Experiment 2: Performance Comparison of Heating Section 5 (Easing Heat and Heat Convection) Experimental subject: a four-layer fashion square sheet (outer fabric + hot melt interlining + shaping mesh + lining fabric).

[0043] Evaluation indicators: heat penetration time (the time required for the center temperature of the fabric layer to reach the adhesive activation temperature of 140℃, unit: s) and adhesive layer temperature uniformity (the temperature distribution range of 9 points in the adhesive layer measured by a thermal imager, unit: ℃).

[0044] It can be known that: Existing technology C, with its pure contact heating, relies on heat conduction from the outside in, resulting in a long heat penetration time (42s). Furthermore, due to uneven pressure between the heating plate and the fabric surface, it causes a significant temperature difference (12.8℃), easily leading to inconsistent bonding strength, localized over-melting, or failure to bond. Existing technology D, with its steam heating, is more uniform than pure contact heating (temperature difference 8.5℃), but its heat transfer efficiency is low, and the temperature rise is slow (65s).

[0045] Heating unit 5 combines radiant heating with forced clean hot air convection penetration. The hot airflow directly penetrates the gaps between the fabric fibers for "three-dimensional" heating, shortening the heat penetration time to 18 seconds and increasing efficiency by 57% and 72% respectively. At the same time, the combined effect of evenly distributed hot air and a high thermal conductivity uniform temperature mesh keeps the temperature difference of the adhesive layer within 3.2℃, achieving rapid and highly uniform heating, directly ensuring the uniformity of adhesive quality and production efficiency.

[0046] Reference Figure 6 and Figure 7 The heat dissipation section 7 is disposed on the upper pressure plate 3, and its core function is to construct a graded, active cooling cycle. It includes heat-conducting pipe columns 71 fixedly installed on the upper pressure plate 3, a heat dissipation cavity 72 formed in the upper pressure plate 3, and a cooling cavity 73 and a recovery cavity 75 formed in the heat-conducting pipe columns 71. The coolant used to cool the upper pressure plate 3 to accelerate the cooling and shaping of the square sheet material circulates in the heat dissipation cavity 72, cooling cavity 73, and recovery cavity 75. The upper pressure plate 3 absorbs a large amount of heat energy from the square sheet material, and the inner wall of the heat dissipation cavity 72 absorbs heat and transfers it to the internal liquid coolant. In some embodiments, the heat-conducting pipe columns 71 also have an air-cooled cavity 74 surrounding the cooling cavity 73, and a booster fan 77 is fixedly installed in the air-cooled cavity 74.

[0047] The heat dissipation cavity 72 is closely attached to the back of the working surface of the upper pressure plate 3. The high specific heat capacity coolant (such as water-ethylene glycol mixture) inside absorbs heat and is then unidirectionally transported to the cooling cavity 73 in the heat-conducting column 71 through the first channel 76 under the suction of the micro magnetic drive gear pump.

[0048] In some embodiments, after the heated high-temperature coolant enters the cooling chamber 73, it completely submerges the densely arranged curved air ducts 78 within it. Simultaneously, the booster fan 77 in the air-cooled chamber 74 activates, forcibly drawing in ambient air that flows through the curved air ducts 78. The tortuous flow path (such as spiral or serpentine) within the ducts greatly increases fluid turbulence and heat exchange area, enabling efficient heat exchange between the two media (high-temperature coolant and cold air) inside and outside the ducts, thereby rapidly reducing the temperature of the coolant outside the ducts. Further explanation: First, a first channel 76 for unidirectional delivery of high-temperature coolant is connected between the heat dissipation chamber 72 and the cooling chamber 73. Under the influence of thermosiphon effect or driven by a micro pump, the heated coolant enters the cooling chamber 73 from the heat dissipation chamber 72 through the first channel 76 for unidirectional delivery of high-temperature coolant.

[0049] Secondly, the air-cooled cavity 74 is connected to a curved air duct 78 that runs through the cooling cavity 73 and is immersed in the high-temperature coolant. In the cooling cavity 73, the curved air duct 78 is immersed in the high-temperature coolant, and the booster fan 77 forces external cold air into the air-cooled cavity 74. The cold air flows through the tortuous path of the curved air duct 78, which greatly increases the heat exchange area and time with the high-temperature coolant, efficiently removes heat, and cools the coolant.

[0050] Then, a second channel 79 for unidirectional delivery of low-temperature coolant is connected between the cooling chamber 73 and the recovery chamber 75. The cooled coolant flows into the recovery chamber 75 through the second channel 79, while the heated air is discharged through the curved cold air duct 78.

[0051] Finally, a third channel 710 for unidirectional replenishment of room-temperature coolant is connected between the recovery chamber 75 and the cooling chamber 73. When the total amount of coolant in the system is slightly reduced or the overall temperature rises due to long-term operation, room-temperature coolant is automatically replenished from the recovery chamber 75 to the cooling chamber 73 through the third channel 710 to ensure the stability of the circulating medium. When the total amount of coolant is slightly reduced due to long-term operation, room-temperature coolant is automatically replenished from the recovery chamber 75 (or an external replenishment tank) to the cooling chamber 73 through the third channel 710.

[0052] To verify the technical superiority of the heat dissipation unit 7, a comparative experiment was conducted with existing conventional technical solutions: Experiment 3: Performance Comparison of Heat Reduction Section 7 (Rapid Forced Cooling and Shaping) Experimental subject: a square fashion sheet that has been hot-pressed and bonded at a temperature of 120℃.

[0053] Evaluation metrics: time required to cool to the setting temperature (35℃) (unit: s) and dimensional change rate of the product within 24 hours after cooling (key metric: change in diagonal length of the sheet, unit: %).

[0054] The liquid-gas dual-medium multi-stage cooling structure helps to significantly improve the cooling rate and energy efficiency ratio compared to single-stage water cooling.

[0055] It can be known that: Existing technology E has an extremely long and uncontrollable natural cooling time, resulting in severe uneven shrinkage and dimensional changes (0.85%), making the product prone to warping and exhibiting extremely poor shaping accuracy. Existing technology F uses a single liquid cooling cycle, which improves the cooling rate (48s), but the coolant temperature rises rapidly after absorbing heat, especially in the initial stage of the cycle. The small cooling temperature difference and insufficient driving force result in insufficient shaping, and the molecular chain segments are slowly frozen while still active, ultimately producing a micro-deformation of 0.25%.

[0056] The heat dissipation section 7 introduces a pressurized air-cooling chamber 74, which uses continuously supplied room temperature air to perform online forced secondary cooling of the circulating high-temperature coolant. This ensures that the coolant always absorbs heat from the fabric with a large temperature difference and high efficiency, reducing the cooling time to 22 seconds, an increase of over 54%. This rapid and intense quenching effect causes the adhesive layer and fibers to lose their internal stress relaxation ability in a very short time, thereby controlling the 24-hour dimensional change rate of the product to an extremely high precision level of 0.05%, fully meeting the stringent requirements of high-end fashion for component dimensional stability.

[0057] Compared to single-stage water cooling, the convective heat transfer resistance of the cooling section 7 is significantly reduced, enabling rapid quenching of the adhesive layer and fibers, quickly fixing their microstructure to an ideal shape and preventing subsequent creep and warping.

[0058] It should be noted that the upper pressure plate 3 uses coolant to cool the bonded fashion square sheet until it solidifies and sets.

[0059] The lower pressure plate 2 is fixedly mounted on the four-legged base 11, and the upper pressure plate 3 is longitudinally slidably mounted on the four guide columns 12, with the upper pressure plate 3 corresponding to the lower pressure plate 2 vertically.

[0060] In some embodiments, four sets of movable supports 42 are equidistantly distributed around the lower pressure plate 2, and the four sets of movable supports 42 adjust the horizontal position of the retainer 45 by radial movement to tighten the square sheet.

[0061] In some implementations, the cooling gas is helium.

[0062] Reference Figure 6The fixed ceiling 13 is provided with a traction part 6 for pulling the upper pressure plate 3 vertically up and down along the guide column 12. It includes a guide rod 61 that is longitudinally slidably installed in the fixed ceiling 13 and fixedly connected to the upper pressure plate 3. A U-shaped rotating shaft 62 is rotatably installed at the upper end of the fixed ceiling 13. A sleeve 63 is movably fitted on the U-shaped rotating shaft 62. A traction rod 64 is pin-connected between the sleeve 63 and the upper pressure plate 3.

[0063] It should be noted that the specific model and specifications of the electric heating wire 53 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail here.

[0064] The functional principle is explained through the following operation method: First, the square fashion sheet to be bonded is placed on the heat-conducting mesh 55. Four movable supports 42, equidistant from each other around the lower pressure plate 2, adjust the horizontal position of their respective upper retainers 45 by radial movement. Each retainer 45 has a telescopic capsule 456 in each of its two T-shaped clamping parts 453. At the same time, cryogenic helium is injected into the telescopic capsule 456 to make it fully expand, thereby forming a flexible and uniform clamping force on the four right-angled ends of the square fashion sheet. Meanwhile, a helium mass spectrometer leak detector will detect whether there is a helium leak in real time to ensure the sealing and reliability of the clamping system. Secondly, after the fastener 45 clamps the right-angle end of the fashion square sheet, the Y-shaped lifting bracket 44 can drive the fastener 45 to make a fine adjustment in the vertical direction, while the moving bracket 42 continues to move slowly outward in the radial direction. The two work together to apply radial tension to the fashion square sheet, so that it is laid flat and taut on the upper surface of the lower pressure plate 2, providing a wrinkle-free flat state for subsequent hot pressing and bonding. Next, driven by the traction unit 6, the upper pressure plate 3 slides vertically downward along the four guide columns 12 and closes with the lower pressure plate 2. At this time, the heating unit 5 is activated. When the electric heating wire 53 is energized, the heat is conducted to the heat-conducting mesh 55 through the heat-conducting elongated hole 56. The fashion square sheet directly contacts the heat-conducting mesh 55, and the heat is evenly transferred to the fashion square sheet. At the same time, the upper pressure plate 3 applies pressure to complete the hot-press bonding. Then, after bonding is complete, to prevent the fabric from deforming or delaminating during natural cooling, immediately activate cooling unit 7: Coolant enters the heat dissipation cavity 72 inside the upper pressure plate 3 from the outside, then flows into the cooling cavity 73 in the heat conduction column 71, and finally flows out through the recovery cavity 75. The upper pressure plate 3 quickly absorbs the heat of the bonded fabric through the coolant and forces it to cool down, so that the bonded layer can be quickly solidified and shaped. In addition, the air-cooled cavity 74 and the curved air duct 78 can help to dissipate heat and improve cooling efficiency. Finally, after the shaping is completed, the traction unit 6 drives the upper pressure plate 3 to rise and reset. At this time, the low-temperature helium gas in the telescopic capsule 456 is discharged or recovered, the T-shaped clamp 453 loses its support, automatically releases the right-angle end of the fabric, and the moving bracket 42 and the Y-shaped lifting bracket 44 reset to their initial positions. The glued and shaped fashion square sheet can then be taken out from the heat-conducting mesh 55.

Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
