Description

Technical Field

[0001] The invention relates to the technical field of textile technology, in particular to a textile oven with uniform heating. Background Art

[0002] Textile ovens are core equipment in finishing processes such as printing, dyeing, setting, and drying. Their heating uniformity directly impacts the color fastness, shrinkage, and hand quality of fiber materials. With the increasing popularity of high-count, high-density fabrics (such as 60S / 2 combed cotton and ultrafine polyester fibers) and functional fabrics (waterproof, breathable, and antimicrobial coatings), the industry is placing higher demands on oven temperature control accuracy (±1°C), dynamic humidity regulation (RH ±5%), and energy efficiency. However, existing textile ovens still suffer from uneven heat distribution. Traditional ovens utilize single-sided straight tube heating or fixed deflector designs, which concentrate heat in localized areas. This can lead to yellowing of fabric edges and coating thickness variations exceeding 10%. Fixed deflector structures are unable to adapt to varying fabric weights, resulting in thick fabrics being prone to "burnt on the outside, wet on the inside" drying, increasing rework rates by 15%-20%.

[0003] In recent years, the industry has attempted to improve through technologies such as CFD flow field simulation and modular sensing, but there are problems such as high cost and poor adaptability of modification. Therefore, there is an urgent need for an integrated solution that takes into account heating uniformity, dynamic response and economy. Summary of the Invention

[0015] The technical solution adopted by the present invention can achieve the following beneficial effects: 1. The present invention provides a uniformly heated textile oven, comprising a heating module equipped with an electric heating tube group and a heat-conducting radiation plate. The electric heating tube group is evenly distributed along the circumference of the oven body, and the surface of the heat-conducting radiation plate is provided with a nano-infrared radiation coating. The electric heating tube group and the heat-conducting radiation plate with the nano-infrared radiation coating work together to achieve uniform heating of the fabric in the oven, while improving heating efficiency. The oven also includes a hot air circulation device and a temperature detection module for feedback control, achieving a temperature fluctuation within the heating chamber of ≤±1.5°C, improving uniformity by more than 40% compared to traditional equipment, while reducing energy consumption by 15%-18%, and solving the problems of product color difference and excessive shrinkage caused by the uneven thermal field in the textile oven.

[0016] 2. The surface of the guide plate in the hot air circulation device is equipped with a wavy guide groove. This wavy guide groove optimizes the hot air diffusion path through airflow segmentation and three-dimensional disturbance. Combined with the angle adjustment mechanism driven by a servo motor (with an accuracy of ±0.1°), it dynamically adjusts to the weight requirements of different fabrics (for example, thick fabrics automatically switch to vertical airflow), reducing the standard deviation of the temperature field by 30% and shortening the response time to within 5 seconds, significantly improving process adaptability.

At the same time, it reduces the frequency of manual cleaning and reduces labor costs.

[0020] 6. The uniformly heated textile drying oven provided by the present invention also includes a humidity regulation module, which includes a condensation dehumidification unit and a steam humidification unit.

The fuzzy logic operation module dynamically adjusts the hot air circulation parameters based on changes in the temperature gradient. The PID + fuzzy logic composite control algorithm constantly suppresses temperature overshoot within a small range. Compared with traditional PID control, the response speed is increased by 2 times. Especially when the fabric load suddenly increases or decreases, it can still maintain a ±1°C fluctuation, ensuring continuous production quality consistency and improving equipment operation stability.

[0022] 8. The oven body is equipped with a self-cleaning device, which includes an ultrasonic cleaning head and a high-pressure air blowing port.

[0027] To make the objectives, technical solutions, and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other implementations obtained by those of ordinary skill in the art without inventive effort are within the scope of protection of the present invention.

It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0029] Textile ovens are core equipment for printing, dyeing, shaping, and drying processes, and their heating uniformity directly impacts product quality. With the increasing popularity of high-count, high-density fabrics and functional fabrics, the industry's requirements for temperature control accuracy, dynamic humidity regulation, and energy efficiency have significantly increased. However, existing equipment faces the following bottlenecks: 1. Uneven heat distribution: Traditional ovens use single-sided straight tube heating or fixed deflector designs, which concentrate heat in a localized area (measured temperature differences exceeding ±6°C). This can lead to yellowing of fabric edges and coating thickness variations exceeding 10%. Fixed deflector structures cannot adapt to the weight variations of different fabrics, and thick fabrics are prone to "burning on the outside and getting wet on the inside" when drying, increasing rework rates by 15%-20%.

[0030] 2. Slow dynamic response: Most equipment relies on manual damper adjustment, requiring downtime of over 30 minutes to switch between materials, resulting in significant capacity loss. Lack of multi-parameter coupled control means humidity fluctuations can easily cause excessive shrinkage of hygroscopic fibers, necessitating secondary shaping.

[0031] 3. Energy efficiency and maintenance challenges: Traditional deflectors create significant wind resistance (drag coefficient of up to 2.5), accounting for up to 40% of fan energy consumption. Fiber lint permanently adheres to the surface of the heating element, reducing thermal efficiency by 20%-30%, necessitating frequent manual cleaning.

[0032] 4. Inadequate safety protection: The single temperature sensor has a response delay exceeding 10 seconds to sudden airflow disturbances, posing a risk of localized overheating. The system also lacks intelligent anti-misoperation features, resulting in an industry-wide accident rate of 0.3 per 1,000 units per year.

[0033] In recent years, the industry has attempted improvements through technologies such as CFD flow field simulation and modular sensing, but these have faced challenges such as high costs and poor adaptability. An integrated solution that balances heating uniformity, dynamic response, and cost-effectiveness is urgently needed.

[0034] The following is combined with Figures 1 to 7 , a textile oven 1 with uniform heating provided by the present application is described in detail through specific embodiments and application scenarios.

[0035] Some embodiments of the present invention provide a textile oven 1 with uniform heating, comprising an oven body 10, wherein a heating chamber 100 is provided in the oven body 10; a heating module 11, wherein the heating module 11 comprises an electric heating pipe group 110 and a heat-conducting radiation plate 111, wherein the electric heating pipe group 110 is evenly distributed along the circumference of the oven body 10, and the surface of the heat-conducting radiation plate 111 is provided with a nano-infrared radiation coating; a hot air circulation device 12, wherein the hot air circulation device 12 comprises an axial flow fan 120, a guide air duct 121 and a guide plate 122, wherein the guide plate 122 is connected to the oven body 10 via an angle adjustment mechanism 123; and a temperature detection module 13, wherein the temperature detection module 13 comprises an infrared temperature sensor. The array and the feedback controller are integrated into one; wherein, the heating module 11, the hot air circulation device 12 and the temperature detection module 13 work together through a control unit 16; it can be understood that the electric heating pipe group 110 and the heat-conducting radiation plate 111 coated with a nano-infrared radiation coating work together to achieve uniform heating of the fabric in the oven and improve the heating efficiency; it also includes feedback control of the hot air circulation device 12 and the temperature detection module 13 to achieve temperature fluctuations in the heating chamber ≤±1.5°C, which improves uniformity by more than 40% compared with traditional equipment, while reducing energy consumption by 15%-18%, solving the problems of product color difference and excessive shrinkage caused by uneven thermal field in the textile oven.

[0036] As an optional embodiment, the nano-infrared radiation coating can be an Al2O3-SiO2 composite nano-coating, the emissivity of which is ε≥0.92, which can effectively reflect most of the heat generated by the electric heating tube group, thereby facilitating heat concentration and improving drying efficiency.

[0037] Specifically, a conveying device 19 is provided in the oven body 10. The fabric is transported by the conveying device 19 into the oven body 10 and the heating chamber 100 to implement a series of drying, heating, dehumidification and other process operations.

[0038] Furthermore, a wavy guide groove 1220 is provided on the surface of the guide plate 122, and the angle adjustment mechanism 123 includes a servo motor and an angle encoder. Specifically, the servo motor is connected to the rotating shaft of the guide plate 122 through a coupling; specifically, the wavy guide groove 1220 can effectively suppress the boundary layer separation phenomenon, and solve the local temperature deviation problem caused by the "eddy current dead zone" in the traditional oven. The wavy guide groove 1220 optimizes the hot air diffusion path through airflow segmentation and three-dimensional disturbance, and cooperates with the angle adjustment mechanism driven by the servo motor (±0.1° accuracy) to dynamically match the grammage requirements of different fabrics (such as automatic switching of vertical airflow for thick fabrics). In actual use, the standard deviation of the temperature field is reduced by 30%, the response time is shortened to within 5 seconds, and the process adaptability is significantly improved.

[0039] Specifically, in order to improve the stability of the equipment and the hot air flow effect, the feedback frequency of the angle encoder is set to ≥10Hz, and the angle adjustment dead zone range is ±2°.

[0040] For further information, please refer to Figure 2 and Figure 5 The inner wall of the heating chamber 100 is provided with a composite insulation layer 101, and the composite insulation layer 101 includes a ceramic fiber layer 1010, a vacuum insulation panel 1011 and an aerogel insulation layer 1012 from the inside to the outside.

[0041] Specifically, the ceramic fiber layer 1010 (inner layer) is resistant to high temperatures and thermal shock, directly blocks heat leakage, and reflects infrared radiation back to the heating chamber; the vacuum insulation panel 1011 (middle layer) uses the extremely low thermal conductivity of the vacuum environment (close to 0.008 W / (m·K)) as a core insulation barrier; the aerogel insulation layer 1012 (outer layer) is an ultra-lightweight porous material that further blocks residual heat, while being waterproof and fireproof, and protecting the internal structure; in actual operation, a composite insulation layer is set with a thermal conductivity coefficient of ≤0.02W / (m·K), which saves more than 25% energy compared to traditional rock wool insulation layers, and the surface temperature of the oven is ≤45°C, reducing heat loss while improving workshop environmental safety.

[0042] Furthermore, the thickness of the composite thermal insulation layer 101 is 80-120 mm.

[0043] Optionally, the thickness of the ceramic fiber layer 1010 is 30-50 mm, the thickness of the vacuum insulation panel 1011 is 20-30 mm, and the thickness of the aerogel insulation layer 1012 is 30-40 mm; it can be understood that limiting the thickness of the composite insulation layer 101 can achieve good insulation effect without squeezing the heating volume of the heating chamber 100, while the materials are used reasonably to improve economic benefits.

[0044] Furthermore, a vibration dust removal device 14 is provided at the bottom of the oven body 10. The vibration dust removal device 14 includes an electromagnetic vibrator 140 and a shock-absorbing spring group 141. The electromagnetic vibrator 140 is connected to the control unit 16. The electromagnetic vibrator 140 removes fiber fluff accumulated on the surface of the electric heating tube group 110 through the resonance effect, and combines with the shock-absorbing spring group 141 to reduce mechanical impact, which can effectively reduce the thermal efficiency attenuation rate and reduce heat loss. At the same time, it reduces the frequency of manual cleaning and reduces labor costs.

[0045] Specifically, the vibration frequency of the electromagnetic vibrator 140 is 20-50 Hz. It is understandable that in order to further improve the vibration dust cleaning effect, the vibration frequency of the electromagnetic vibrator 140 corresponds to 0.8-1.2 times the natural frequency of the structure of the oven body 10.

[0046] Furthermore, some embodiments of the present invention disclose a textile oven 1 with uniform heating, which also includes a humidity control module 15. The humidity control module 15 includes a condensation and dehumidification unit 150 and a steam humidification unit 151. The condensation and dehumidification unit 150 includes a compressor, an evaporator and a drain solenoid valve 1501. The steam humidification unit 151 includes an electrode humidifier 1510 and a humidity sensor 1511. Specifically, this embodiment adopts a compression and evaporation integrated machine 1500.

[0047] It is understandable that textiles often go through processes such as high-temperature dehumidification-low-temperature moisturizing-steam setting during the heating and drying process. The humidity requirements of textiles are different in each process. The condensation dehumidification unit 150 drives the refrigerant circulation through the compressor to form a low-temperature zone on the evaporator surface, so that the moisture in the air is condensed into liquid water and discharged through the drain solenoid valve 1501, and the dehumidification efficiency reaches more than 90%; and the electrode humidifier 1510 in the steam humidification unit 151 generates saturated steam through current control, which quickly increases the humidity to the process requirements; the condensation dehumidification and steam humidification dual-mode linkage supports seamless switching between low-temperature and low-humidity drying of wool and high-temperature and high-humidity setting of polyester, prevents differences in fiber shrinkage and static electricity accumulation caused by humidity fluctuations, supports drying most textile products made of different materials on the market, and reduces process debugging time.

[0048] Furthermore, the control unit 16 includes a PID temperature controller 160 and a fuzzy logic operation module 161. The integral time Ti of the PID temperature controller 160 is 30-60s, and the differential time Td is 5-10s. The fuzzy logic operation module 161 dynamically adjusts the hot air circulation parameters according to the temperature gradient change. It can be understood that the fuzzy logic operation module 161 adjusts the hot air circulation parameters in real time by analyzing the temperature gradient change rate of the infrared temperature sensor array. The PID+fuzzy logic composite control algorithm always suppresses the temperature overshoot within a smaller range, thereby improving the accuracy. Compared with traditional PID control, the response speed is increased by 2 times, especially when the fabric load suddenly increases or decreases, it can still maintain a ±1°C fluctuation, ensuring the consistency of continuous production quality and improving the stability of equipment operation.

[0049] Optionally, the AI ​​control (such as neural network prediction) interface can be expanded in the fuzzy logic module 161, and the fuzzy rule base can be optimized through historical data training; the temperature and humidity in the cavity can be controlled more accurately by combining the humidity sensor 1511 signal to predict the trend of fiber moisture content changes.

[0050] For further information, please refer to Figure 7The oven body 10 is equipped with a self-cleaning device 17 comprising an ultrasonic cleaning head 170 and a high-pressure air blowing port 171. Understandably, traditional textile ovens rely on manual maintenance, resulting in blind spots for cleaning (such as gaps between heating tubes and at corners in the air duct), which can lead to localized overheating or airflow disturbances after long-term operation. This solution integrates ultrasonic cleaning and air blowing cleaning into the oven system, enabling online automated cleaning and ensuring continuous production. The dual cleaning mode of ultrasonic cleaning and high-pressure air blowing automatically removes residue from the chamber walls during the equipment's standby period, effectively reducing downtime for maintenance and preventing secondary contamination of coated fabrics by chemical cleaning agents.

[0051] Specifically, in routine daily cleaning, the ultrasonic cleaning head 170 is set to a power of 20-40kHz, and the high-frequency vibration produces a cavitation effect, which destroys fiber debris and oil stains attached to the inner wall of the chamber, the guide plate and other surfaces, and is particularly suitable for removing micron-level pollutants on the surface of the nano-infrared radiation coating; the high-pressure air blowing port 171 is set to 0.4-0.8MPa compressed air pulse jet to quickly remove large particle residues (such as broken yarn ends, dust agglomerates), forming a complementary cleaning mode with the ultrasonic wave; optionally, a brush head can also be set in the oven body, first use the brush head to clean the pollutants that are easier to clean, and then perform the ultrasonic and air blowing cleaning modes to further improve the cleaning effect.

[0052] Furthermore, a safety protection component 18 is provided at the front of the oven body 10 . The safety protection component 18 includes an observation window 180 , an infrared sensor 181 and an emergency brake button 182 . The infrared sensor 181 is connected to the control unit 16 .

[0053] Specifically, observation window 180 provides a transparent monitoring interface. Made of heat-resistant tempered glass or quartz glass, it allows operators to observe the internal status of heating chamber 100 (e.g., textile drying progress, abnormal smoke emission, etc.) in real time, avoiding safety risks caused by unintentional operation. Infrared sensor 181 uses non-contact detection with a detection range of 50-200 cm. When a person or foreign object enters the danger zone, a trigger signal is transmitted to control unit 16, automatically shutting off power to heating module 11 or hot air circulation device 12. Emergency stop button 182 utilizes a mechanical physical circuit breaker, enabling manual forced shutdown in the event of a sudden fault (e.g., overtemperature alarm, fire), ensuring the safety of both personnel and equipment.

[0054] Its overall warning logic is: the observation window 180 provides the first level of manual warning; the infrared sensor 181 realizes the second level of automatic warning; the emergency brake button 182 serves as the final physical insurance; forming a three-level safety closed loop of "monitoring-warning-intervention", which significantly reduces the accident rate and contributes to safe production.

[0055] Specifically, the power-off priority of the emergency brake button 182 is set to the highest level.

[0056] It is understandable that when the oven is working, the temperature of the box body is high after a long period of heating. The operator may accidentally touch the box body when observing the working status inside the oven, causing burns. The infrared sensor 181 and the emergency brake button 182 are linked and controlled to quickly cut off the power supply when the operator accidentally touches the door body. Combined with the high-temperature resistant glass design of the observation window 180, the safety accident rate is effectively reduced.

[0057] Compared with the prior art, the textile oven with uniform heating provided by the present invention has the following beneficial effects: 1. The present invention provides a uniformly heated textile oven, comprising a heating module equipped with an electric heating tube group and a heat-conducting radiation plate. The electric heating tube group is evenly distributed along the circumference of the oven body, and the surface of the heat-conducting radiation plate is provided with a nano-infrared radiation coating. The electric heating tube group and the heat-conducting radiation plate with the nano-infrared radiation coating work together to achieve uniform heating of the fabric in the oven, while improving heating efficiency. The oven also includes a hot air circulation device and a temperature detection module for feedback control, achieving a temperature fluctuation within the heating chamber of ≤±1.5°C, improving uniformity by more than 40% compared to traditional equipment, while reducing energy consumption by 15%-18%, and solving the problems of product color difference and excessive shrinkage caused by the uneven thermal field in the textile oven.

[0058] 2. The surface of the guide plate in the hot air circulation device is equipped with a wavy guide groove. This wavy guide groove optimizes the hot air diffusion path through airflow segmentation and three-dimensional disturbance. Combined with the angle adjustment mechanism driven by a servo motor (with an accuracy of ±0.1°), it dynamically adjusts to the weight requirements of different fabrics (for example, thick fabrics automatically switch to vertical airflow), reducing the standard deviation of the temperature field by 30% and shortening the response time to within 5 seconds, significantly improving process adaptability.

[0059] 3. A composite insulation layer is provided on the inner wall of the heating chamber. The composite insulation layer includes a ceramic fiber layer, a vacuum insulation panel, and an aerogel insulation layer from the inside out. The composite insulation layer has a thermal conductivity of ≤0.02W / (m·K), which saves more than 25% energy compared to traditional rock wool insulation. The oven surface temperature is ≤45°C, reducing heat loss while improving workshop environmental safety.

[0060] 4. Limiting the thickness of the composite insulation layer can achieve good insulation effect without squeezing the heating volume of the heating chamber. At the same time, the material is used reasonably to improve economic benefits.

[0061] 5. A vibration dust removal device is provided at the bottom of the oven body. The vibration dust removal device includes an electromagnetic vibrator and a shock-absorbing spring group. The electromagnetic vibrator is connected to the control unit. The electromagnetic vibrator removes the fiber fluff accumulated on the surface of the heating tube through the resonance effect. Combined with the shock-absorbing spring group, it reduces mechanical shock, which can effectively reduce the thermal efficiency attenuation rate and heat loss. At the same time, it reduces the frequency of manual cleaning and reduces labor costs.

[0062] 6. The uniformly heated textile drying oven provided by the present invention also includes a humidity regulation module, which includes a condensation dehumidification unit and a steam humidification unit. The condensation dehumidification unit includes a compressor, an evaporator and a drain solenoid valve, and the steam humidification unit includes an electrode humidifier and a humidity sensor. The condensation dehumidification and steam humidification dual-mode linkage supports seamless switching between low-temperature and low-humidity drying of wool and high-temperature and high-humidity shaping of polyester, supports drying most textile products made of different materials on the market, and reduces process debugging time.

The PID temperature controller has an integral time Ti of 30-60s and a differential time Td of 5-10s. The fuzzy logic operation module dynamically adjusts the hot air circulation parameters based on changes in the temperature gradient. The PID + fuzzy logic composite control algorithm always suppresses temperature overshoot within a small range. Compared with traditional PID control, the response speed is increased by 2 times. Especially when the fabric load suddenly increases or decreases, it can still maintain a ±1°C fluctuation, ensuring continuous production quality consistency and improving equipment operation stability.

The dual cleaning mode of ultrasonic cleaning + high-pressure air blowing can automatically remove residues on the inner wall of the chamber during the equipment standby period, effectively reducing downtime for maintenance and avoiding secondary contamination of the coated fabric by chemical cleaning agents.

[0065] 9. A safety protection component is provided at the front of the oven body, which includes an observation window, an infrared sensor and an emergency brake button. The infrared sensor is connected to the control unit. When the oven is working, the temperature of the oven body is high after a long period of heating.
