Description

Technical Field

[0001] This invention relates to the field of garment pressing control technology, specifically to a garment pressing temperature and pressure linkage control device. Background Technology

[0002] The garment pressing temperature and pressure linkage control device refers to the control device that coordinates temperature control and pressure control during the pressing process of garments (finished sewn clothing). It is used to apply precisely controlled high temperature and pressure to garments or fabrics to achieve process purposes such as wrinkle removal, shaping, bonding or printing curing. Ironing and shaping is a key process that determines the appearance quality and wearing effect of garments. At present, the conventional operation method for ironing and shaping garments in the industry is as follows: the operator first manually flattens and arranges the garment, smooths out the wrinkles, and then uses an ironing machine to perform a one-time pressing operation along the surface of the garment. During the sewing and folding process, residual rotational stress accumulates inside the fibers of garment fabrics. When the operator manually smooths out the wrinkles, the fibers will rebound under the action of elastic recovery force, causing the area that was just smoothed to wrinkle again in a short time. Because there is no secondary smoothing mechanism for pre-smoothing or auxiliary shaping in front of and around the sides of the ironing head, the fabric in a certain area is still in a natural relaxed or wrinkled rebound state before the ironing head reaches a certain area. When the ironing head passes directly over the wrinkled area that has not been completely smoothed out, the fabric in the wrinkled area is forced to be pressed and shaped under the combined action of pressure and high temperature, forming hard indentation wrinkles that are difficult to eliminate, affecting the overall ironing effect and visual consistency of the garment. Therefore, it is necessary to design a garment pressing temperature and pressure linkage control device. By using a secondary flattening mechanism during the pressing process, the rotational stress of the fabric can be eliminated and the formation of indentations and wrinkles can be prevented, thereby fundamentally solving the above-mentioned technical problems and improving the quality and production efficiency of garment pressing. Summary of the Invention

[0003] The purpose of this invention is to provide a garment pressing temperature and pressure linkage control device, which solves the problems mentioned in the background art.

[0004] To achieve this objective, the present invention adopts the following technical solution: A garment pressing temperature and pressure linkage control device includes a pressing frame, a mounting platform on the top of the pressing frame, a control panel on the front of the mounting platform for switching preset pressing parameters corresponding to the garment, a temperature and pressure control device on the right side of the pressing frame for controlling the steam temperature and pressure according to different fabrics, a negative pressure pressing platform on the top of the mounting platform, a pressing iron on the top of the negative pressure pressing platform, and a leveling scraper, a leveling roller and an auxiliary roller mounted on the outer edge of the pressing iron by a fixing component. The leveling scraper, the leveling roller and the auxiliary roller are arranged sequentially from front to back along the ironing direction and are located in front of the pressing working surface at the bottom of the pressing iron, for pre-scraping and pre-removing of garment wrinkles by roller pressing before ironing. The iron includes an iron body with an operating handle on top and an on / off button at the bottom for controlling steam discharge. An air inlet pipe is installed on one side of the iron body, and several steam discharge holes are located at the bottom. A temperature and pressure sensor is installed in the air inlet pipe for monitoring temperature and pressure. The signal output of the temperature and pressure sensor is electrically connected to the signal input of a temperature and pressure control device. The temperature and pressure control device is electrically connected to an external steam generator for signal interaction, forming a closed-loop temperature and pressure control system with parameter preset, real-time monitoring, and feedback adjustment.

[0005] Furthermore, the fixing assembly includes a protective shell fixedly installed on the outer wall of the iron body, a roller pressing mechanism, and a scraping mechanism. The scraping mechanism includes a positioning frame fixedly installed on the outer side of the inner wall of the protective shell. A limiting cavity is opened inside the positioning frame. A plurality of abutment springs are evenly installed on the top wall of the limiting cavity. The movable end of each abutment spring is fixedly installed with the same limiting slide. The limiting slide is located in the limiting cavity and slides in a limited manner.

[0006] Furthermore, a connecting seat is fixedly installed at the bottom of the limiting slide, and the bottom of the connecting seat is fixedly connected to the leveling scraper. The abutment spring provides a downward elastic preload to the leveling scraper, so that the leveling scraper can adapt to changes in fabric thickness and maintain a contact pressure when it comes into contact with the garment fabric.

[0007] Furthermore, the roller pressing mechanism includes an air inlet chamber opened inside the leveling roller. The leveling roller is rotatably mounted on the inner side of the inner wall of the protective shell. The hollow roller shaft of the leveling roller passes through the protective shell and extends to the outside. The hollow roller shaft of the leveling roller is connected to an air supply pipe through a leak-proof bearing. The air supply pipe is connected to the steam pipe inside the iron body.

[0008] Furthermore, the outer wall of the leveling roller is evenly provided with several mounting grooves in a circumferential direction. Fixing frames are fixedly installed on both sides of the inner wall of the air inlet cavity at positions corresponding to the mounting grooves. The inner wall of each fixing frame is provided with an embedded groove. A positioning shaft is vertically installed on the inner wall of each embedded groove. A sliding mounting block is slidably installed on the outer wall of the positioning shaft. The side of the sliding mounting block near the auxiliary roller is rotatably connected to its roller shaft. A return spring is installed between the sliding mounting block and the inner wall of the embedded groove and sleeved on the outer wall of the positioning shaft. One end of the return spring is fixedly connected to the bottom wall of the sliding mounting block, and the other end of the return spring is fixedly connected to the bottom wall of the embedded groove.

[0009] Furthermore, multiple auxiliary rollers are evenly distributed circumferentially along the outer wall of the leveling roller. The outer wall of the auxiliary roller protrudes from the outer wall of the leveling roller, so that the auxiliary roller contacts the garment fabric before the leveling roller. When the leveling roller drives the auxiliary roller to roll and level the garment, the force mounting groove of the auxiliary roller retracts back into the inner wall of the air inlet cavity, so that the steam inside the air inlet cavity is discharged outward through the mounting groove, and the garment wrinkles are pre-removed by steam.

[0010] Furthermore, a pipe guiding mechanism is installed on the rear wall of the heat press frame. The pipe guiding mechanism includes a mounting horizontal plate fixedly installed on the rear part of the outer wall of the heat press frame. An L-shaped upright is fixedly installed on the rear wall of the mounting horizontal plate. A horizontal frame is fixedly installed at the front end of the L-shaped upright. A rolling cavity is opened in the inner wall of the horizontal frame. A roller groove is opened in the inner wall of the rolling cavity. A movable roller is rotatably installed in the inner wall of the roller groove.

[0011] Furthermore, a follower block is installed between the axles of the movable roller, and a conveying pipe is installed on the inner wall of the follower block. The top end of the conveying pipe is connected to the air outlet of the external steam generator, and the bottom end of the conveying pipe is connected to the air inlet pipe. The movable roller reciprocates along the roller groove, driving the follower block and the conveying pipe to adaptively follow and guide the movement of the pressing iron to prevent the conveying pipe from getting tangled or pulled.

[0012] Furthermore, the negative pressure heat treatment platform includes a platform body with an internal cavity, the rear wall of the platform body is connected to an external negative pressure device through a pipe, a placement platform is installed on the top of the platform body, and an adsorption plate with multiple micropores on its surface is installed on the inner wall of the placement platform.

[0013] Furthermore, a protective sleeve is fitted onto the outer wall of the placement platform and the adsorption plate for placing garments for wrinkle removal during processing. The negative pressure device generates a downward adsorption force on the garments through the internal cavity of the platform body and the micropores on the adsorption plate, keeping the garments flat and fitted during the ironing process and preventing the fabric from shifting or wrinkling under the action of the secondary flattening mechanism.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. This garment pressing temperature and pressure linkage control device features a pre-flattening mechanism in front of the iron pressing surface, consisting of a scraper for pre-smoothing and a roller for pre-removing wrinkles. This mechanism releases residual rotational stress within the fabric in stages. First, the elastic floating flattening scraper pushes forward the rebound folds, and then the humid steam softens the fibers and, combined with roller pressing, further stretches and shapes the fabric. This ensures that the fabric remains stretched before the main pressing process, completely avoiding the risk of folds being forcibly pressed together. Compared to traditional single-pressing processes, this significantly reduces the fold rebound rate of the fabric after ironing, and significantly improves the smoothness and visual consistency of the garment surface, effectively reducing subsequent rework and repair processes.

[0015] 2. This garment pressing temperature and pressure linkage control device uses a control panel to store process parameters for various fabrics. Combined with real-time monitoring and feedback from the temperature and pressure sensors on the iron itself, the temperature and pressure control equipment dynamically regulates the external steam generator in a closed loop. This achieves one-click matching and stable output of steam temperature and pressure throughout the process. It can quickly adapt to the optimal temperature and pressure parameters based on the characteristics of different fabrics, avoiding problems such as fabric damage from excessively high temperatures or poor shaping due to insufficient pressure. Simultaneously, it can offset fluctuations in steam parameters during long-term operation, ensuring consistent garment quality across different batches and ironing areas, and significantly reducing reliance on operator experience and technique.

[0016] 3. This garment pressing temperature and pressure linkage control device uses a negative pressure pressing platform with microporous adsorption plates. It uses uniform negative pressure to stretch and fix the garment, initially releasing the fiber rotation stress. This not only avoids fabric displacement during ironing but also helps to suppress the natural rebound tendency of wrinkles. The negative pressure fixing and pre-flattening mechanism work together to simultaneously complete the fabric fixing and wrinkle flattening operations. There is no need for operators to repeatedly manually adjust the fabric, which greatly reduces the intensity and time consumption of manual flattening operations. It is especially suitable for continuous ironing operations of large-area garments such as coats and shirts, effectively improving the output efficiency per unit time.

[0017] 4. The garment pressing temperature and pressure linkage control device features a spring-floating structure for the flattening scraper, which adapts to changes in fabric thickness and seam protrusions, ensuring uniform bonding pressure without scratching delicate fabrics. The flattening roller adopts a contact-type adaptive steam outlet structure, opening the steam outlet to output steam when in contact with the fabric and automatically sealing the steam outlet when separating to reduce ineffective steam loss. It is also equipped with a follow-up pipeline guide mechanism, allowing the steam delivery pipe to move flexibly with the iron without pulling or tangling, thus broadening the device's adaptability to different types and thicknesses of garments.

[0018] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0023] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component positioned centrally in the connection.

[0025] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0026] Please see Figures 1-16This invention provides a garment pressing temperature and pressure linkage control device, including a pressing machine frame 1, a mounting platform 3 on the top of the pressing machine frame 1, a control panel 4 on the front of the mounting platform 3 for switching preset pressing parameters corresponding to the garment, a temperature and pressure control device 2 on the right side of the pressing machine frame 1 for controlling the steam temperature and pressure according to different fabrics, a negative pressure pressing platform 5 on the top of the mounting platform 3, a pressing iron 7 on the top of the negative pressure pressing platform 5, a leveling scraper 9, a leveling roller 10 and an auxiliary roller 11 are installed on the outer edge of the pressing iron 7 by a fixing component 8, the leveling scraper 9, the leveling roller 10 and the auxiliary roller 11 are arranged from front to back along the ironing direction, and are located in front of the bottom pressing working surface of the pressing iron 7, for pre-scraping and pre-removing of garment wrinkles by roller pressing before ironing; The iron 7 includes an iron body 72, an operating handle 71 mounted on the top of the iron body 72, and an on / off button mounted on the bottom of the operating handle 71 for controlling the steam discharge. An air inlet pipe 73 is mounted on one side of the iron body 72, and several steam discharge holes are opened at the bottom of the iron body 72. A temperature and pressure sensor 74 for temperature and pressure monitoring is installed in the air inlet pipe 73. The signal output terminal of the temperature and pressure sensor 74 is electrically connected to the signal input terminal of the temperature and pressure control device 2. The temperature and pressure control device 2 is electrically connected to an external steam generating device for signal interaction, forming a closed loop of temperature and pressure linkage control with parameter preset, real-time monitoring, and feedback adjustment.

[0027] In this implementation scheme, by arranging the leveling scraper 9, leveling roller 10, and auxiliary roller 11 in front of the pressing work surface of the pressing iron 7, a step-by-step ironing process of pre-leveling and main pressing is constructed. This can fully release the residual rotational stress inside the fabric fibers before the main pressing process, avoiding the defect of wrinkles being forcibly pressed together under high temperature and high pressure to form hard indentations. At the same time, relying on the closed-loop control link formed by the temperature and pressure sensor 74 and the temperature and pressure control device 2, real-time dynamic calibration of steam parameters is achieved, ensuring the adaptability of ironing processes for different fabrics, and implementing the core control logic of temperature and pressure linkage from a structural level.

[0028] Specifically, the fixing component 8 includes a protective shell 81 fixedly installed on the outer wall of the iron body 72, a roller pressing mechanism 82, and a scraping mechanism 83. The scraping mechanism 83 includes a positioning frame 831 fixedly installed on the outer side of the inner wall of the protective shell 81. A limiting cavity 832 is opened inside the positioning frame 831. Several abutment springs 833 are evenly installed on the top wall of the limiting cavity 832. The movable end of each abutment spring 833 is fixedly installed with the same limiting slide 834. The limiting slide 834 is located in the inner wall of the limiting cavity 832 and slides in a limited manner.

[0029] In this embodiment, the circumferential limitation of the limiting slide 834 by the limiting cavity 832 and the elastic support of the abutment spring 833 are combined to provide a stable vertical floating degree of freedom for the leveling scraper 9. This ensures the structural rigidity during the leveling operation and can automatically adjust the vertical position according to the undulation of the fabric surface, avoiding the problem of scraper jamming and fabric scratching caused by uneven fabric thickness or seam protrusion, and improving the adaptability and operational stability of the pre-leveling process.

[0030] Specifically, a connecting seat 835 is fixedly installed at the bottom of the limiting slide 834. The bottom of the connecting seat 835 is fixedly connected to the leveling scraper 9. The abutment spring 833 provides a downward elastic preload to the leveling scraper 9, so that the leveling scraper 9 can adapt to changes in fabric thickness and maintain a close fit pressure when it comes into contact with the garment fabric.

[0031] In this embodiment, the abutment spring 833 transmits a constant elastic preload to the flattening scraper 9 through the connecting seat 835, so that the scraper always adheres to the fabric surface with uniform pressure. During the ironing process, the rebounding folds can be gradually pushed and stretched along the direction of travel, further releasing the residual rotational stress inside the fibers, improving the uniformity of fold flattening and work efficiency, while avoiding local fold residue caused by uneven flattening force during manual operation.

[0032] Specifically, the rolling mechanism 82 includes an air inlet chamber 826 opened inside the leveling roller 10. The leveling roller 10 is rotatably mounted on the inner side of the inner wall of the protective housing 81. The hollow roller shaft of the leveling roller 10 passes through the protective housing 81 and extends to the outside. The hollow roller shaft of the leveling roller 10 is connected to an air supply pipe 827 through a leak-proof bearing. The air supply pipe 827 is connected to the steam pipe inside the iron body 72.

[0033] In this embodiment, the air inlet chamber 826 of the leveling roller 10 takes the main steam source of the iron body 72 through the air supply pipe 827. At the same time, it can ensure that the steam temperature and pressure parameters of the pre-wrinkle removal process and the main pressing process are consistent, so that the fabric fibers can obtain the wet heat softening effect that matches the main pressing in the pre-leveling stage, and ensure the process synergy between the front and back processes.

[0034] Specifically, the outer wall of the leveling roller 10 is provided with a number of mounting grooves 828 evenly distributed in the circumference. On both sides of the inner wall of the air inlet chamber 826, and at the positions corresponding to the mounting grooves 828, a fixing frame 821 is fixedly installed. The inner wall of the fixing frame 821 is provided with an embedded groove 822. The inner wall of the embedded groove 822 is vertically installed with a positioning shaft 823. A sliding mounting block 825 is slidably installed on the outer wall of the positioning shaft 823. The side of the sliding mounting block 825 near the auxiliary roller 11 is rotatably connected to its roller shaft. A return spring 824 is installed between the sliding mounting block 825 and the inner wall of the embedded groove 822 and sleeved on the outer wall of the positioning shaft 823. One end of the return spring 824 is fixedly connected to the bottom wall of the sliding mounting block 825, and the other end of the return spring 824 is fixedly connected to the bottom wall of the embedded groove 822.

[0035] In this embodiment, the sliding guide provided by the inner groove 822 of the fixing frame 821 and the positioning shaft 823 for the sliding mounting block 825, combined with the elastic reset action of the reset spring 824, enables the auxiliary roller 11 to have stable telescopic rebound capability, which can provide sufficient contact pressure for the auxiliary roller 11 to ensure the rolling effect, and can automatically reset and seal the mounting groove 828 when it is separated from the fabric, thus realizing adaptive control of steam on and off from the mechanical structure level.

[0036] Specifically, multiple auxiliary rollers 11 are evenly distributed around the outer wall of the leveling roller 10. The outer wall of the auxiliary rollers 11 protrudes from the outer wall of the leveling roller 10, so that the auxiliary rollers 11 contact the garment fabric before the leveling roller 10. When the leveling roller 10 drives the auxiliary rollers 11 to roll and level the garment, the auxiliary rollers 11 are retracted into the inner wall of the air inlet chamber 826 by the force mounting groove 828, so that the steam inside the air inlet chamber 826 is discharged outward through the mounting groove 828, and the garment wrinkles are pre-removed by steam.

[0037] In this implementation scheme, by means of the structural design of the auxiliary roller 11 protruding from the roller surface, the roller first contacts and contracts under force, the mounting groove 828 opens to release steam, and the roller surface follows up with the roller pressing in a continuous operation. The steam can directly act on the fabric area that has just been scraped flat, quickly soften the fiber structure and eliminate residual internal stress, and complete the secondary pre-wrinkle removal in conjunction with the roller pressing action of the leveling roller 10. This process allows the fabric to be in a relaxed and softened state before reaching the main pressing work, fundamentally eliminating the formation of hard indentations, while improving the final shaping effect and reducing the wrinkle rebound rate.

[0038] Specifically, a pipe guiding mechanism 6 is installed on the rear wall of the heat press frame 1. The pipe guiding mechanism 6 includes a mounting plate 61 fixedly installed on the rear part of the outer wall of the heat press frame 1. An L-shaped upright 62 is fixedly installed on the rear wall of the mounting plate 61. A transverse frame 63 is fixedly installed at the front end of the L-shaped upright 62. A rolling cavity 64 is opened in the inner wall of the transverse frame 63. A roller groove 65 is opened in the inner wall of the rolling cavity 64. A movable roller 66 is rotatably installed in the inner wall of the roller groove 65.

[0039] In this embodiment, the mounting plate 61 and the L-shaped upright 62 form a stable support structure, providing a reliable installation foundation for the horizontal frame 63. The cooperative design of the rolling cavity 64 and the roller groove 65 provides a limited rolling path for the movable roller 66, which not only ensures the smooth movement of the pipeline but also restricts the vertical movement of the follower block 67, avoiding the problem of shaking or knotting of the conveying pipe 68 during the follow-up process.

[0040] Specifically, a follower block 67 is installed between the axles of the movable roller 66, and a conveying pipe 68 is installed on the inner wall of the follower block 67. The top end of the conveying pipe 68 is connected to the air outlet of the external steam generator, and the bottom end of the conveying pipe 68 is connected to the air inlet pipe 73. The movable roller 66 reciprocates along the roller groove 65, driving the follower block 67 and the conveying pipe 68 to adaptively follow and guide the movement of the pressing iron 7 to prevent the conveying pipe 68 from getting tangled or pulled.

[0041] In this implementation scheme, the follower block 67 rolls with low resistance within the transverse frame 63 via the movable roller 66, and can move synchronously with the lateral movement of the pressing iron 7 without jamming. This effectively straightens the direction of the delivery pipe 68, avoiding problems such as pulling, tangling, and knotting of the pipe when the iron moves over a large range. It not only ensures the pressure stability of the steam delivery, but also expands the operating range of the iron, improving the smoothness and safety of the operator's work.

[0042] Specifically, the negative pressure heat treatment platform 5 includes a platform body 54 with an internal cavity. The rear wall of the platform body 54 is connected to an external negative pressure device through a pipe. A placement platform 52 is installed on the top of the platform body 54. An adsorption plate 53 with multiple micropores on its surface is installed on the inner wall of the placement platform 52.

[0043] In this embodiment, the internal cavity of the platform body 54 serves as a negative pressure buffer chamber, which can keep the microporous air pressure in each area of ​​the adsorption plate 53 uniform and consistent, forming a uniform adsorption force in a surface area. This uniform negative pressure can stretch and expand the fabric along the plane, suppressing the natural rebound tendency of wrinkles, and providing a stable working foundation for subsequent pre-flattening and pressing processes.

[0044] Specifically, a protective sleeve 51 is fitted onto the outer wall of the placement platform 52 and the adsorption plate 53 for placing garments for wrinkle removal. The negative pressure device generates a downward adsorption force on the garments through the internal cavity of the platform body 54 and the micropores on the adsorption plate 53, so that the garments remain flat and close together during the ironing process, preventing the fabric from shifting or wrinkling under the action of the secondary flattening mechanism.

[0045] In this implementation scheme, the breathable and high-temperature resistant protective cover 51 can not only evenly transmit the negative pressure adsorption force, but also prevent the fabric from directly contacting the hard adsorption plate 53, thus avoiding wear or burn marks and protecting the surface quality of the garment. The downward pulling force generated by negative pressure adsorption can fix the garment on the table. Combined with the pushing action of the pre-positioned secondary flattening mechanism, it effectively prevents the fabric from shifting or wrinkling during the scraping and rolling process, ensuring the flattening effect of the pre-flattening process and further improving the stability of the overall ironing quality.

[0046] Working principle of the garment pressing temperature and pressure linkage control device: The ironing operator selects the corresponding preset pressing parameters through the control panel 4 at the front of the operating platform 3 according to the type of garment fabric to be ironed. Each set of preset parameters includes the target steam temperature value and the target delivery pressure value. The control panel 4 then outputs a control signal to the temperature and pressure control device 2. The temperature and pressure control device 2 controls the steam temperature and pressure output by the external steam generator to match the selected preset parameters, ensuring that the steam output matches the fabric characteristics during the subsequent pressing process.

[0047] The garment to be ironed is placed on the area at the top of the placement platform 52 and the adsorption plate 53. Since the protective sleeve 51 is attached to the outside of the placement platform 52 and the adsorption plate 53, after the garment is placed in the area of ​​the adsorption plate 53, the external negative pressure equipment is activated to draw air into the platform body 54 through the pipeline to form a negative pressure, so that the multiple micropore areas on the surface of the adsorption plate 53 form a uniform negative pressure adsorption area, and the garment placed on the top of the protective sleeve 51 is adsorbed and fixed downward. The staff roughly smooths out the parts of the garment that need ironing. Because residual rotational stress has accumulated inside the fibers during the sewing and folding process, when the operator manually smooths out the wrinkles, the fibers will rebound under the action of elastic recovery force, causing the area that was just smoothed to wrinkle again. At this time, the uniform negative pressure adsorption force generated by the adsorption plate 53 can apply a continuous downward restraining force to the garment fabric, effectively inhibiting the rebound of some wrinkles with less elasticity, so that the fabric remains relatively flat and ready for ironing on a macroscopic level. The introduction of negative pressure adsorption force can suppress shallow wrinkles with less elasticity. For deep wrinkles with greater internal rotational stress and stronger elasticity, it is still necessary to rely on subsequent secondary smoothing for active intervention.

[0048] The operator uses the handle 71 to move the iron body 72 and the air inlet pipe 73 simultaneously. The iron body 72 is placed at the starting position of the garment to be ironed. Then, the operator presses the on / off button at the bottom of the handle 71, so that the external steam enters the iron body 72 through the delivery pipe 68 and the air inlet pipe 73, and the high-temperature steam is discharged from several exhaust holes at the bottom. Simultaneously, the operator pushes the handle 71 to move the iron body 72 towards the direction of the wrinkles. As the iron body 72 is pushed forward, it will simultaneously drive the protective shell 81, the leveling scraper 9, and the leveling roller 10 to move. Along the direction of travel of the pressing iron 7, the leveling scraper 9, the auxiliary roller 11, the leveling roller 10, and the iron body 72 will act on the garment fabric in sequence, forming a progressive leveling process. During the advancement process, the positioning frame 831 drives the limiting slide 834, connecting seat 835 and leveling scraper 9 to level along the pressing direction. Since the bottom surface of the leveling scraper 9 is lower than the bottom surface of the iron body 72, the leveling scraper 9 contacts the garment fabric before the iron body 72, and pre-scrapes the rebound folds in front of the traveling direction before the iron body 72 arrives. The abutment spring 833 installed inside the limiting cavity 832 applies a continuous downward elastic preload to the limiting slide 834, so that the leveling scraper 9 can adapt to changes in fabric thickness and maintain constant bonding pressure when it comes into contact with the garment fabric. When the local thickness of the fabric increases, the limiting slide 834 slides upward along the inner wall of the limiting cavity 832 to compress the abutment spring 833, so as to avoid excessive scraping pressure and damage to the fabric fibers. When the local thickness of the fabric decreases, the abutment spring 833 releases elastic potential energy to push the limiting slide 834 downward, so as to ensure that the leveling scraper 9 always maintains effective contact with the fabric and no blind spots in scraping occur. The pre-scraping action of the leveling scraper 9 forces the resilient wrinkled fibers to flatten them into a smooth state, creating conditions for subsequent steam softening and roller pressing. Through the process sequence of first scraping and then pressing, the fabric fibers are heat-set in a naturally flattened state, effectively avoiding irreversible indentation defects caused by forced pressing.

[0049] When the leveling roller 10 rolls inside the protective shell 81 along the pushing direction of the iron body 72, it will drive the auxiliary roller 11 to roll synchronously inside the mounting groove 828. Since the outer wall of the auxiliary roller 11 protrudes from the outer wall of the leveling roller 10, the auxiliary roller 11 contacts the garment fabric before the leveling roller 10, and performs the first round of roller pressure contact on the fabric that has been pre-scraped flat by the leveling scraper 9. When the leveling roller 10 drives the auxiliary roller 11 to roll and level the garment, the auxiliary roller 11 is subjected to the reaction force of the fabric and contracts into the air inlet chamber 826 along the mounting groove 828. At this time, the mounting groove 828 is in the open state. The steam inside the air inlet chamber 826 is precisely discharged outward through the mounting groove 828 to the contact area between the auxiliary roller 11 and the fabric. The high temperature steam softens the fabric fibers at the roller pressing contact point, thereby releasing the residual rotational stress accumulated inside the fibers. Combined with the rolling pressure of the leveling roller 10, the softened wrinkled fibers are pre-wrinkled and pre-shaped by roller pressing. After the auxiliary roller 11 rolls over the fabric surface, under the elastic restoring force of the return spring 824, it pushes the sliding mounting block 825 back along the outer wall of the positioning shaft 823 and guides it to slide and reset in the inner groove 822 of the fixed frame 821. The auxiliary roller 11 is then reset and protrudes out of the outer wall of the leveling roller 10 again. At the same time, the sliding mounting block 825 seals the mounting groove 828 to prevent steam from overflowing through the mounting groove 828 in a non-contact state, causing energy waste and safety hazards. The linkage opening and closing structure of the auxiliary roller 11 and the mounting groove 828 in this device realizes a dynamic process closed loop of roller contact, steam release, fiber softening, stress release and roller shaping. The steam is released only at the moment when the auxiliary roller 11 actually contacts the fabric, which not only ensures that the steam energy is concentrated on the wrinkled area, but also avoids the ineffective steam diffusion in non-working areas, which significantly improves the steam utilization efficiency and wrinkle removal accuracy. The roller pressing action of the auxiliary roller 11 makes the fabric fibers accept steam softening under pressure. The steam softening under roller pressure can more thoroughly eliminate the elastic energy stored inside the fibers, so that the fabric will no longer rebound when pressed by the iron body 72 in the subsequent process.

[0050] After the pre-smoothing by the leveling scraper 9 and the pre-wrinkle removal by the steam rollers 11 and 10, the garment fabric is in a flat state and the fiber rotation stress is fully released. At this time, the soleplate of the iron body 72 reaches this area to perform comprehensive ironing and wrinkle removal and final heat setting of the garment folds. Since the fabric fibers have completed stress release and preliminary setting in the secondary pretreatment, the ironing action of the iron body 72 completes the final temperature curing and setting. There is no need to force the unflattened folds with excessive pressure, thereby completely avoiding the generation of hard indentations and wrinkles, and ensuring the overall ironing effect and visual consistency of the garment.

[0051] When the iron body 72 moves on the negative pressure ironing platform 5, it will drive the air inlet pipe 73 and the delivery pipe 68 to move synchronously. The delivery pipe 68 drives the follower block 67 and the movable roller 66 to move in the inner wall of the horizontal frame 63. The movable roller 66 rolls freely in the inner wall of the roller groove 65 of the rolling cavity 64, while the follower block 67 moves in the interior of the horizontal frame 63. The follow-up design of the pipeline guiding mechanism 6 ensures that the delivery pipe 68 remains naturally suspended during the large-scale movement of the iron body 72, preventing the delivery pipe 68 from being entangled, pulled, or excessively bent, which would reduce the internal cross-sectional area of ​​the steam pipeline and cause fluctuations in steam delivery pressure, thus affecting the temperature and pressure control device 2's regulation of steam parameters. Throughout the ironing process, the temperature and pressure sensor 74 built into the iron body 72 monitors the steam delivery pressure and temperature in real time and feeds the collected signals back to the control panel 4. The control panel 4 compares the actual temperature and pressure values ​​with the preset target values ​​in real time. When a deviation is detected that exceeds the allowable threshold, the control panel 4 sends an adjustment command to the temperature and pressure control device 2. The temperature and pressure control device 2 immediately adjusts the output parameters of the external steam generator, so that the steam temperature and pressure are always maintained within the preset parameter range, forming a closed-loop control loop of acquisition, comparison, adjustment, and execution. This achieves dynamic compensation and maintenance of temperature and pressure parameters, ensuring that the secondary smoothing mechanism operates under good temperature and pressure conditions throughout the entire process, making the release of fiber rotational stress and heat setting effect consistent and repeatable.

[0052] In summary, this device employs a progressive process—negative pressure adsorption to suppress rebound, pre-smoothing with a leveling scraper 9, pre-wrinkle removal with steam rollers 11, and full-body pressing and shaping with an iron 72—coupled with real-time support from a closed-loop temperature and pressure control system. This solves the problem of wrinkles and rebound caused by the rotational stress of garment fabric fibers, allowing the fabric fibers to undergo final heat setting in a naturally flattened and stress-released state. This fundamentally eliminates the conditions for the formation of hard indentations and wrinkles, significantly improving the quality and production efficiency of garment pressing.
