Description

Technical Field

[0001] This utility model relates to the field of garment production and processing equipment technology, and in particular to a high-efficiency hot circulation rapid ironing device for garment production. Background Technology

[0002] Ironing, a crucial step in garment production, primarily aims to eliminate wrinkles and shape garments, thereby enhancing their overall appearance and wearing quality. With the rapid development of the garment industry, existing ironing equipment has made significant progress in operation, automation, and ironing effectiveness. Various advanced ironing technologies and equipment are constantly emerging, providing diverse solutions for garment manufacturers. Currently, the ironing equipment on the market mainly includes traditional steam irons, electric irons, and some high-end ironing equipment integrated with automated control systems. These devices play a vital role in improving ironing efficiency and quality.

[0003] However, existing ironing technologies still suffer from low energy efficiency. Traditional ironing processes generate large amounts of high-temperature, high-humidity steam, which is typically released directly into the work environment. This not only results in significant energy waste (the steam contains a large amount of latent and sensible heat that is not effectively utilized), but also leads to a sharp increase in humidity and temperature in the workshop, worsening working conditions and potentially harming workers' health. While some high-end ironing equipment on the market may integrate rudimentary steam management systems, these systems often focus on steam generation and jet control, with insufficient consideration given to the effective recovery and reuse of waste steam generated after ironing. Even when some equipment attempts to recover heat, its structure is often complex, manufacturing costs are high, or recovery efficiency is low, making it difficult to widely apply and promote in ordinary garment manufacturing enterprises that prioritize cost-effectiveness.

[0004] Therefore, how to develop an ironing device with a relatively compact structure, controllable manufacturing cost, good ironing effect, and efficient recovery and recycling of the heat steam energy generated during the ironing process, so as to achieve the goals of energy saving, consumption reduction, improvement of working environment and improvement of overall production efficiency, is a technical problem that urgently needs to be solved in the field of garment ironing equipment. Utility Model Content

[0005] The technical problem to be solved by this utility model is to address the low energy utilization rate of existing ironing equipment, the direct emission of hot steam generated during ironing leading to energy waste and deterioration of the working environment, as mentioned in the background art. This invention provides a high-efficiency thermal circulation rapid ironing device for garment production that can effectively capture and recover hot steam and hot air penetrating clothing during ironing, use the recovered heat energy to preheat the medium entering the ironing system, and simultaneously condense the steam to reduce the emission of hot and humid gases, improve the working environment, and ensure a relatively reasonable device structure, easy integration, and maintain fast and efficient ironing performance.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A high-efficiency heat circulation rapid ironing device for garment production includes a frame, an ironing unit mounted on the frame, and a heat circulation system.

[0008] The ironing unit includes a lower ironing board and an upper ironing head that can be raised and lowered relative to the lower ironing board;

[0009] The lower ironing board is horizontally fixed on the frame, and its upper surface forms the ironing working surface. The lower ironing board is equipped with a first heating device, and several suction holes are evenly opened on the ironing working surface.

[0010] The upper ironing head is located above the lower ironing board and is connected to the frame via a lifting mechanism. The upper ironing head is equipped with a second heating device.

[0011] The heat cycle system includes:

[0012] The heat recovery chamber is located below the lower ironing plate and is connected to the suction through hole on the lower ironing plate.

[0013] The ventilation guiding device includes a ventilation fan, the air inlet of which is connected to the heat recovery chamber through a first connecting pipe;

[0014] The preheating and condensing integrated device has its inlet connected to the outlet of the exhaust fan via a second connecting pipe. The device integrates a heat exchange preheating channel and a condensation collection area.

[0015] Preferably, the heat exchange preheating channel is provided with a serpentine pipeline consisting of multiple serpentine tubes.

[0016] Preferably, the outer wall of the preheating and condensing integrated device is provided with heat dissipation fins, and the condensation collection area inside is provided with cooling coils.

[0017] Preferably, one end of the first heating device is provided with a medium inlet, which is connected to one end of the heat exchange preheating channel.

[0018] Preferably, the inner wall of the heat recovery chamber and the outer wall of the connecting pipe are covered with a layer of thermal insulation material.

[0019] Preferably, the rapid ironing device further includes a garment tensioning mechanism, which is disposed on both sides of the working surface of the lower ironing plate and includes at least two pairs of adjustable garment clamps.

[0020] The beneficial effects of this utility model include the following:

[0021] By constructing a complete closed-loop heat energy recovery and reuse circuit, the specially designed heat recovery chamber actively captures the high-temperature and high-humidity steam that penetrates the clothing after ironing. Then, through the integrated preheating and condensation device, the heat energy contained in the steam is efficiently transferred to the working medium entering the system, directly reducing the initial energy input required to heat these media. This significantly reduces the overall operating energy consumption of the device and improves energy utilization efficiency.

[0022] The active ventilation system in the heat circulation system can quickly and effectively remove excess moisture from the inside and surface of clothes during the ironing process while recovering heat, shortening the drying time of clothes, speeding up the overall ironing rhythm, and obtaining a smoother, drier iron with better shaping effect.

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments, but these specific embodiments do not limit the scope of protection of the present invention in any way. Example

[0027] like Figure 1-2As shown, a high-efficiency thermal circulation rapid ironing device for garment production includes a frame 1, an ironing unit, a garment tensioning mechanism, and a thermal circulation system. This device is mainly used in the ironing process of garment production and processing. It can efficiently recover the hot steam and hot air generated during ironing, achieving thermal energy recycling, significantly reducing energy consumption, and improving the working environment.

[0028] The frame 1 is the basic support structure for the entire device. The bottom of the frame 1 is equipped with adjustable support feet to ensure that the device is installed horizontally under different ground conditions and to ensure the stability of the device.

[0029] The ironing unit is the core working component of the device, including a lower ironing plate 2 and an upper ironing head 5. The lower ironing plate 2 is horizontally fixed on the frame 1, and its upper surface forms a flat ironing work surface. The lower ironing plate 2 is equipped with a first heating device 3, which uses steam heating to provide a uniform and stable heating temperature for the lower ironing plate 2. Several suction holes 4 are evenly distributed on the ironing work surface of the lower ironing plate 2. These suction holes 4 have a moderate diameter, which effectively guides steam and hot air downwards without damaging the clothing.

[0030] The upper ironing head 5 is located directly above the lower ironing plate 2 and is connected to the frame 1 via a lifting mechanism 6. The lifting mechanism 6 is driven by a cylinder or a servo motor to achieve the vertical lifting movement of the upper ironing head 5. The upper ironing head 5 is equipped with a second heating device 7 (electric heating), which works in conjunction with the heating system of the lower ironing plate 2 to form a double-sided heating ironing method. The lower surface of the upper ironing head 5 is designed to be flat and match the working surface of the lower ironing plate 2 to ensure uniform pressure on the clothes.

[0031] The garment tensioning mechanism is located on the edge of the working surface of the lower ironing plate 2, and includes four pairs of adjustable garment clamps 8. Each pair of garment clamps 8 is located on the four edges of the lower ironing plate 2, and can symmetrically clamp different parts of the garment. The garment clamps 8 have a structure that can slide and lock along the guide rails on the edge of the lower ironing plate 2. The operator can quickly adjust the clamping position and lock it. The clamping surface of the clamps 8 is covered with a soft material (such as rubber or plastic) to prevent damage to the garment, while providing sufficient friction to ensure that the garment is firmly tensioned.

[0032] The heat circulation system includes a heat recovery chamber 9, an exhaust fan, and an integrated preheating and condensation unit.

[0033] The heat recovery chamber 9 is a sealed box structure located directly below the lower ironing plate 2. The top opening of the heat recovery chamber 9 directly connects to all the suction holes 4 on the lower ironing plate 2, forming a completely enclosed collection space. The heat recovery chamber 9 effectively collects hot steam and hot air penetrating the clothing and the lower ironing plate 2 without causing excessive airflow resistance. The inner wall of the heat recovery chamber 9 is covered with a layer of thermal insulation material to minimize heat loss during collection. An outlet flange is located on the side of the heat recovery chamber 9 for connecting to the subsequent piping system.

[0034] The ventilation system includes an exhaust fan 10 and a connecting duct system. The exhaust fan 10 is a variable frequency speed-regulating centrifugal fan. The air inlet of the exhaust fan 10 is connected to the outlet of the heat recovery chamber 9 via a first connecting duct 11. The duct connection uses a sealed flange structure to ensure good airtightness. The exhaust fan 10 can generate a stable negative pressure, actively extracting the hot steam and hot air collected in the heat recovery chamber 9. The exhaust fan 10 is equipped with a variable frequency controller, and its airflow can be precisely adjusted according to the type and thickness of the ironing fabric and the ironing process parameters to achieve an optimal balance between steam penetration and heat recovery efficiency.

[0035] The integrated preheating and condensing unit is a key component of the heat circulation system. Its inlet is connected to the outlet of the exhaust fan via a second connecting pipe 12. The unit adopts a vertical rectangular cabinet structure, integrating two functional areas: a heat exchange preheating channel 13 and a condensation collection area 15.

[0036] The heat exchange preheating channel 13 is located at the top of the device. Multiple serpentine tubes 14 are spirally distributed within the heat exchange preheating channel 13, forming a serpentine pipeline, which increases the heat exchange area. The medium to be heated flows through these serpentine tubes 14, exchanging heat fully with the high-temperature steam and hot air entering from the second connecting pipe 12. The serpentine tubes 14 are made of copper tubes with good thermal conductivity and moderate wall thickness, ensuring both sufficient strength and good heat transfer effect. During the heat exchange process, the heat from the high-temperature steam and hot air is effectively transferred to the medium to be heated inside the tubes, realizing the recovery and utilization of heat energy.

[0037] Inside the integrated preheating and condensing unit, the high-temperature, high-humidity gas entering from the second connecting pipe 12 first enters the heat exchange preheating channel 13. Within this channel 13, the gas makes full contact with and efficiently passes over the outer surface of the serpentine tube bundle 14 to achieve optimal heat exchange efficiency. During this process, the gas releases most of its sensible heat and some of its latent heat, causing its temperature to decrease. It then flows from the outlet of the heat exchange preheating channel 13 to the lower condensation collection area 15.

[0038] Upon entering the condensation collection zone 15, the gas flow rate slows down and comes into further contact with multiple condensation plates 16 inclined on the inner wall of the cabinet, causing the water vapor carried within to fully condense into liquid water. The temperature of the treated non-condensable gas (mainly air and a small amount of incompletely condensed water vapor) has been significantly reduced, and it is finally discharged into the atmosphere through the exhaust port 22 on the device housing. To prevent external debris from entering or condensate from splashing out, the exhaust port 22 is equipped with a dustproof mesh cover. The bottom of the condensation collection zone 15 is equipped with a condensate collection tank 17 and a drain outlet, which discharges the gas from the device through a drain pipe 18. In addition, the outer wall of the preheating and condensation integrated device housing is also equipped with heat dissipation fins to enhance the overall heat dissipation effect, further improve condensation efficiency, and ensure that the steam is liquefied as completely as possible.

[0039] In specific heat recovery applications, before entering the heating core, a portion of the steam generator's inlet pipe of this device carries the medium to be heated through the heat exchange preheating channel 13 of the integrated preheating and condensing unit. The medium to be heated is the inlet water supplied to the first heating device 3 (i.e., the steam generator) of the lower ironing board 2. After exiting from the water source 19, the steam generator's inlet pipe is first introduced to the inlet 20 of the integrated preheating and condensing unit. The medium to be heated in this preheating section of the inlet pipe meanders through the heat exchange preheating channel 13 inside the integrated preheating and condensing unit, exchanging heat with the high-temperature steam and hot air entering from the second connecting pipe 12. The preheated water is then led out from the outlet 21 of the medium to be heated and connected to the inlet of the steam generator. This increases the water temperature entering the steam generator, thereby reducing the heat input required for the steam generator to heat the water to working steam, achieving efficient heat energy recycling.

[0040] To further optimize the heat circulation effect, the outer walls of the heat recovery chamber 9, connecting pipes, and the integrated preheating and condensation unit are all covered with a layer of thermal insulation material. The insulation material uses high-efficiency insulation cotton, which has good thermal insulation performance and high temperature resistance, and can minimize heat loss during transportation and processing.

[0041] The working principle and method of the above-mentioned high-efficiency heat circulation rapid ironing device for garment production are as follows:

[0042] The first step involves the operator laying the garment to be ironed flat on the working surface of the lower ironing board 2, ensuring that the garment is free of obvious wrinkles and overlaps. Then, the operator adjusts the positions of the various clamps 8 in the garment tensioning mechanism to accommodate the size and shape of the garment. The operator slides the clamps 8 along the guide rail to the appropriate position, and then activates the clamping function of the clamps 8 to apply appropriate tension to the garment, ensuring that it remains flat during ironing and preventing the formation of new wrinkles.

[0043] The second step involves activating the heating system of the ironing unit. The first heating device 3 begins heating the lower ironing board 2, while the second heating device 7 simultaneously heats the upper ironing head 5. The temperature control system precisely controls the temperature of the upper and lower heating devices based on the characteristics of the garment fabric and the ironing process requirements. During the heating process, if steam heating is used, the steam generated by the steam generator is preheated by an integrated preheating and condensing device before entering the heating channel, achieving efficient utilization of thermal energy.

[0044] Third, once the ironing unit reaches the preset temperature, the operator activates the lifting mechanism 6, causing the upper ironing head 5 to slowly descend to the position where it contacts the clothing. The lifting mechanism 6 precisely controls the descent speed and the final pressing force to ensure that even and appropriate pressure is applied to the clothing. Simultaneously, the heat circulation system is activated, and the variable frequency fan in the exhaust guide device starts working, generating negative pressure in the heat recovery chamber 9.

[0045] Fourthly, during the ironing process, the high-temperature steam generated by the lower ironing board 2 and the upper ironing head 5 penetrates the clothing fibers, eliminating wrinkles and setting the garment's shape. The hot steam and hot air penetrating the clothing are guided into the heat recovery chamber 9 through the suction holes 4 on the working surface of the lower ironing board 2. The heat recovery chamber 9 gathers and collects this dispersed hot steam and hot air, forming a concentrated high-temperature and high-humidity airflow.

[0046] Fifth, the exhaust fan 10 extracts the collected hot steam and hot air from the heat recovery chamber 9 through the first connecting pipe 11, and transports them to the preheating and condensing integrated device through the second connecting pipe 12. In the heat exchange preheating channel 13 of the preheating and condensing integrated device, the high-temperature steam and hot air fully exchange heat with the medium to be heated flowing inside the pipe, transferring the heat energy they carry to the medium to be heated, thus realizing the recovery and utilization of heat energy.

[0047] In the sixth step, the steam, having undergone heat exchange and cooled, continues to flow downwards into the condensation and collection zone 15. Within the condensation zone 15, the steam is further cooled and gradually condenses into liquid water, significantly reducing the amount of high-temperature, high-humidity gas emitted into the workshop environment. The condensed liquid water collects in the collection tank 17 and is discharged through the drainage pipe 18 in the drainage system, achieving water resource recovery. A small amount of low-temperature gas, after condensation, is discharged through the exhaust port 22; its temperature and humidity are greatly reduced, having a negligible impact on the working environment.

[0048] Step 7: After ironing, the operator raises the ironing head 5 to detach it from the garment surface. The heating and ventilation systems are then turned off, the garment tensioning mechanism is released, and the ironed garment is removed. Throughout the ironing process, the heat circulation system operates continuously, constantly recovering and utilizing the heat generated during ironing, significantly reducing the device's energy consumption.

[0049] Throughout the operation, the variable frequency speed control exhaust fan 10 can adjust the airflow according to the ironing needs of different fabrics. For thicker or denser fabrics, the exhaust volume can be increased to enhance the penetration of steam and the removal of moisture; for thinner or fragile fabrics, the exhaust volume can be reduced to avoid excessive negative pressure damaging the fabric. This flexible adjustment capability ensures the device's adaptability to various types of fabrics.

[0050] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any innovative improvements or substitutions based on the present invention should fall within the scope of the claims of the present invention. Furthermore, the parameters, materials, and processes mentioned in the above embodiments are not unique. Without departing from the technical essence of the present invention, those skilled in the art can make various alternative choices, and these alternative solutions should also be considered to fall within the scope of protection of the present invention.
