Description

Technical Field

[0001] The present invention relates to the technical field of drying devices, in particular to a drying device for producing composite fabrics, and in particular to a drying method for the drying device for producing composite fabrics. Background Art

[0002] Composite fabric is a new type of material made by bonding one or more layers of textile materials, non-woven materials and other functional materials. It is suitable for making textiles such as sofas and clothing. It is one of the indispensable fabrics for people's home life. After the composite fabric is produced, the wet composite fabric needs to be dried. This process requires the use of a drying device.

[0003] Chinese patent CN218349149U discloses a drying device for composite fabric production, including a panel table, a drying box and a fixed frame, the drying box and the fixed frame are both fixed to the top surface of the panel table, and the fixed frame is located on the right side of the drying box, there are two fixed frames, and an upper guide roller and a lower guide roller are arranged between the two fixed frames, and a feeding port is opened on both sides of the drying box, and a mounting frame is fixed to the top surface of the panel table, and an automatic winding component is arranged on the mounting frame. In the utility model, the drying box dries the composite fabric, and before drying, two turntables are rotated at the same time, so that the threaded rod moves with the moving key in the moving rail until the upper guide roller and the lower guide roller squeeze the composite fabric, so that the composite fabric squeezes out its internal moisture during the drying and conveying process, reduces the moisture contained in the composite fabric, and thus reduces the drying time of the composite fabric.

[0004] Although the above-mentioned device can dehumidify the composite fabric passing through the drying box, when facing the composite fabric with high humidity, it often takes a long time to achieve the ideal drying effect by simply increasing the temperature in the drying box. This is because although high temperature can accelerate the evaporation of water, in a high humidity environment, the water molecules are more tightly bound to the fabric fibers, and it takes a longer time of continuous heating to effectively separate them. Since the drying process needs to maintain a high temperature, heating elements such as electric heating wires need to work for a long time, resulting in a significant increase in energy consumption. This not only increases production costs, but also does not conform to the current environmental protection concept of energy conservation and emission reduction. During the drying process, the moisture on the fabric evaporates into water vapor. If these hot steams are directly discharged into the air, it will not only waste thermal energy resources, but may also have a certain impact on the environment. However, most of the existing drying devices lack an effective hot steam separation and recovery mechanism, resulting in this part of the thermal energy resources being wasted.

[0015] A drying method of a drying device for composite fabric production, comprising the following steps;

[0016] S1. Feed the composite fabric to be dried through the entrance of the drying box, ensure that the fabric is placed flatly at the preset starting position, start the synchronous clamping device, and prepare for the clamping operation of the composite fabric.

[0017] S2. The synchronous clamping device is started, and the laminating spraying device and the laminating suction device are precisely controlled to move synchronously to both sides of the composite fabric. The working ends of the two devices are opposite to each other and accurately clamp the composite fabric between them to ensure that the composite fabric maintains stability and consistency during the drying process to prevent deviation or wrinkles.

[0018] S3. The laminating spraying device starts to work, spraying the heated gas preheated by the heating device to the bottom of the composite fabric. The heated gas tightly and evenly covers the surface of the composite fabric, and uses the high temperature to accelerate the evaporation of moisture on the surface and inside of the composite fabric, thereby improving the heat transfer efficiency and making the dehumidification process faster.

[0019] S4. At the same time, the laminating suction device is started to form a strong negative pressure area above the composite fabric, which quickly sucks up the hot and humid gas that passes through the composite fabric to ensure that the moisture is effectively removed and avoid negative impact on the drying effect of the composite fabric.

[0020] S5. The sucked hot and humid gas enters the reflux dehumidification device, and is effectively filtered to recover the moisture in the gas while trying to keep the temperature of the gas. Although the temperature of the gas after dehumidification has dropped, it still maintains a relatively high temperature and then enters the heating device for reheating. The heating device adjusts the gas temperature according to actual needs to ensure that the temperature of the gas sprayed onto the composite fabric again is appropriate. The above steps form a closed circulation system, and the heated gas is continuously sprayed on the composite fabric to accelerate the evaporation of moisture, while the suction device continuously extracts, dehumidifies and reheats the hot and humid gas for reuse in the drying process.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. The device achieves rapid and uniform heating and evaporation of moisture on the surface and inside of the composite fabric through the cooperation of the innovative laminating spray pressure device and laminating suction device. The spray pressure device precisely sprays the heating gas, and the negative pressure zone formed by the suction device effectively accelerates the process of hot gas penetrating the fabric, thereby significantly improving the drying efficiency. At the same time, this close cooperation ensures the uniform distribution of heat on the fabric, avoids the problem of local overheating or uneven drying, and improves the quality consistency of the fabric after drying.

[0023] 2. The closed-loop system designed in the device, including the linkage of the reflux dehumidification device and the heating device, realizes the efficient recovery and reuse of hot steam. The hot gas after dehumidification is reheated and reused for fabric drying, which greatly reduces energy consumption. Compared with the traditional method of dehumidification by simply increasing the temperature of the box, this recycling mechanism significantly reduces production costs.

[0024] 3. The device effectively avoids direct discharge of hot steam during the drying process. It removes moisture from the steam and recovers heat energy through the reflux dehumidification device, reducing thermal pollution to the external environment. At the same time, since the demand for new heat sources is reduced, carbon emissions caused by energy consumption are also reduced, which helps protect the ecological environment.

[0039] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0040] See also Figures 1 to 12 As shown, a drying device for composite fabric production includes a high-efficiency quick-drying device installed inside a drying box 1, and the high-efficiency quick-drying device includes a laminating spraying device 2, a laminating suction device 3, a reflux dehumidification device 4, a heating device 5 and a synchronous clamping device 6; the synchronous clamping device 6 is installed on the drying box 1; the laminating spraying device 2 and the laminating suction device 3 are symmetrically installed on the synchronous clamping device 6, and the working ends of the laminating spraying device 2 and the laminating suction device 3 are relatively arranged, the laminating spraying device 2 is used to spray heating gas to the composite fabric 7, and the laminating suction device 3 is used to suck the heating gas passing through the composite fabric 7; the reflux dehumidification device 4 is arranged above the laminating suction device 3, the input end of the reflux dehumidification device 4 is connected to the output end of the laminating suction device 3, and the reflux dehumidification device 4 is used to filter and recover the heating gas; the heating device 5 is arranged beside the reflux dehumidification device 4, the input end of the heating device 5 is connected to the output end of the reflux dehumidification device 4, and the output end of the heating device 5 is connected to the input end of the laminating spraying device 2.

[0041] When the composite fabric 7 needs to enter the drying process, it is first fed in through the entrance of the drying box 1. At this time, the synchronous clamping device 6 is started, which accurately controls the synchronous movement of the laminating spraying device 2 and the laminating suction device 3, and accurately clamps the composite fabric 7 between the two. This step ensures the stability and consistency of the composite fabric 7 during the drying process and prevents the fabric from being offset or wrinkled under high-speed airflow. The laminating spraying device 2 starts to work and sprays the heated gas preheated by the heating device 5 to the bottom of the composite fabric 7. These heated gases are tightly covered on the surface of the fabric, and the high temperature is used to accelerate the evaporation of moisture on the surface and inside of the fabric. Because the spraying method is tight and uniform, the heat transfer efficiency is effectively improved, making the dehumidification process faster. At the same time, the laminating suction device 3 is started to form a strong negative pressure area, which quickly sucks up the hot and humid gas after passing through the composite fabric 7. These hot and humid gases then enter the reflux dehumidification device 4, which can effectively filter and recover the moisture in the gas while maintaining the temperature of the gas. After the dehumidification treatment, the temperature of the gas decreases but still remains at a relatively high temperature. This part of the gas then enters the heating device 5 for reheating. The heating device 5 adjusts the gas temperature according to actual needs to ensure that the temperature of the gas sprayed onto the composite fabric 7 again is appropriate, which not only ensures the dehumidification effect but also avoids energy waste. The above process forms a closed circulation system, so that the composite fabric 7 can achieve the ideal drying effect in a very short time. At the same time, due to the effective recovery and reuse of hot air, energy consumption is greatly reduced.

[0042] The close cooperation between the laminating spraying device 2 and the laminating suction device 3 enables the hot air to penetrate the composite fabric 7 more effectively, thereby improving the uniformity and depth of dehumidification. In addition, the direct contact between the heated gas and the composite fabric 7 further promotes the evaporation and diffusion of moisture, significantly improving the drying efficiency and quality. The heating device 5 is a prior art and will not be described in detail here.

[0043] See also Figure 2 , Figure 4 and Figure 5 As shown, the bonding spraying device 2 includes a first limit mounting plate 21 installed on the synchronous clamping device 6, and a plurality of first rotating mounting grooves 211 are provided on the first limit mounting plate 21. Dehumidification rollers 22 are installed inside the first rotating mounting grooves 211. The dehumidification rollers 22 are covered with air outlet holes, and a plurality of heat conducting plates are evenly distributed along the axial direction of the dehumidification roller 22. A shielding guide device 23 is installed on the first limit mounting plate 21.

[0044] The dehumidification roller 22 serves as a medium to support the composite fabric 7, and also sprays the heated gas preheated by the heating device 5 through the air outlet holes on its surface. These heated gases directly and evenly cover the surface of the composite fabric 7, and use the high temperature to accelerate the evaporation of moisture inside and on the surface of the fabric. The dehumidification roller 22 is designed with spaced heat-conducting plates inside. These heat-conducting plates not only enhance the thermal conductivity of the roller, ensuring that the heated gas can be evenly and efficiently transferred to the fabric, but also enhance the structural strength of the roller, enabling it to work stably. The shielding guide device 23 is installed on the first limiting mounting plate 21. Its main function is to accurately control the spraying range of the dehumidification roller 22, avoid waste of hot air, and ensure that the hot air can accurately act on the effective area of ​​the fabric. At the same time, the shielding guide device 23 also plays a role in guiding the limiting movement of the composite fabric 7, further preventing the fabric from shifting during the drying process.

[0045] See also Figure 4 and Figure 5 As shown, the shielding guide device 23 includes a bidirectional ball screw slide 231 installed on the side of the first limit mounting plate 21, and the movable ends of the bidirectional ball screw slide 231 are installed with mounting frames 232, and a shielding layer 233 is installed on the mounting frame 232. A guide shaft 234 is also provided on the side of the mounting frame 232.

[0046] Function of the dehumidification roller 22: As a medium for supporting the composite fabric 7, the dehumidification roller 22 not only carries the movement of the fabric during the drying process, but also sprays the heated gas preheated by the heating device 5 through the densely distributed air outlets on its surface. The heated gas directly and evenly covers the surface of the composite fabric 7, and uses the high temperature to quickly accelerate the evaporation of moisture inside and on the surface of the fabric, thereby achieving efficient dehumidification.

[0047] The bidirectional ball screw slide 231 synchronously adjusts the distance between the two mounting frames 232 through its precise control capability. This adjustment process is carried out according to the actual size of the composite fabric 7, ensuring that the mounting frame 232 can fit the two sides of the composite fabric 7, laying the foundation for the subsequent shielding and guiding work. A shielding layer 233 is installed on the mounting frame 232, and the main function of the shielding layer 233 is to accurately control the spraying range of the dehumidification roller 22. When the heated gas is sprayed from the dehumidification roller 22, the shielding layer 233 can effectively prevent the hot gas from diffusing to non-target areas, avoid the waste of hot gas, and ensure that the hot gas can accurately act on the effective area of ​​the fabric. At the same time, the shielding layer 233 also plays a certain role in heat preservation, reducing the loss of heat during the transfer process. The side of the mounting frame 232 is also provided with a guide shaft 234, which is in direct contact with the composite fabric 7 and plays a role in guiding the fabric to move in a limited position. During the drying process, the fabric moves forward steadily under the guidance of the guide shaft 234, effectively preventing the fabric from being offset due to high-speed airflow or other factors. The shielding and guiding device 23 can accurately control the spraying range and guide the movement of the fabric, further improving the drying efficiency and quality.

[0048] See also Figure 2 , Figure 4 , Figure 6 and Figure 7 As shown, the laminating suction device 3 includes a second limit mounting plate 31 arranged directly above the first limit mounting plate 21, the second limit mounting plate 31 is fixedly connected to the movable end of the synchronous clamping device 6, and a plurality of second rotating mounting grooves 311 are distributed at intervals on the second limit mounting plate 31, and a suction filter shaft 32 is installed inside the second rotating mounting grooves 311, and a suction inner shaft 321 is provided inside the suction filter shaft 32, and a filter sleeve is provided on the outer sleeve of the suction inner shaft 321, and the suction inner shaft 321 is slidably connected to the suction filter shaft 32, and the suction inner shaft 321 is synchronously connected through the synchronous connecting plate 33, and the laminating suction device 3 also includes an air suction pump 34, the input end of the air suction pump 34 is connected to the suction inner shaft 321, and the output end of the air suction pump 34 is connected to the input end of the reflux dehumidification device 4.

[0049] When the air suction pump 34 is started, negative pressure will be generated inside the suction inner shaft 321. This negative pressure is the basis for the operation of the suction device, and is used to suck up the hot and humid gas that passes through the composite fabric 7. Due to the cooperation between the suction inner shaft 321 and the filter sleeve, when negative pressure is generated, the hot and humid gas that passes through the composite fabric 7 is first sucked into the suction inner shaft 321. When these gases pass through the filter sleeve, the impurities in them will be effectively filtered out, thereby protecting subsequent equipment from damage. The filtered gas continues to be extracted by the suction pump and sent to the reflux dehumidification device 4 through a pipeline for further processing. The suction inner shaft 321 is synchronously connected through the synchronous connecting plate 33, which is convenient for synchronous disassembly and maintenance of the suction inner shaft 321 during later maintenance.

[0050] See also Figure 1 and Figure 8 As shown, the synchronous cleaning device 35 includes a lifting platform 351 arranged beside the second limiting mounting plate 31, and a mounting base 352 is provided on the top of the lifting platform 351. A plurality of docking grooves are installed on the mounting base 352, and the number of the docking grooves matches that of the suction inner shaft 321. Cleaning brushes 3521 are provided inside the docking grooves. A synchronous mounting rail 353 is also installed on the mounting base 352, and a transmission wheel 354 is installed on the synchronous mounting rail 353. A rotating drive device 355 for synchronously driving the plurality of transmission wheels 354 to rotate is also installed on the synchronous mounting rail 353.

[0051] When the filter sleeve layer needs to be cleaned, the suction inner shaft 321 is first disassembled synchronously through the synchronous connecting plate 33. Subsequently, the lifting platform 351 is operated to raise the mounting base 352 to an appropriate height, so that the suction inner shaft 321 can be smoothly moved to the top of the mounting base 352 and accurately docked in the corresponding docking groove. After the suction inner shaft 321 is docked in place, the cleaning brush 3521 is in a suitable position on the outer filter sleeve layer, ready for cleaning. The rotary drive device 355 is started to drive multiple transmission wheels 354 to rotate synchronously. The transmission wheel 354 contacts the outer surface of the suction inner shaft 321 and drives it to rotate, so that the fluff and other foreign matter on the surface of the filter sleeve layer are effectively removed under the action of the cleaning brush 3521. After cleaning, the rotary drive device 355 is turned off and the lifting platform 351 stops moving. The cleaned suction inner shaft 321 can be reinstalled on the second limit mounting plate 31 to continue working.

[0052] Through the cooperation of the synchronous mounting rail 353 and the rotating drive device 355, the automatic rotating cleaning of the suction inner shaft 321 is realized, which greatly improves the cleaning efficiency. The synchronous disassembly and installation of the suction inner shaft 321 through the synchronous connecting plate 33 simplifies the cleaning process and reduces the difficulty of operation. The design of the cleaning brush 3521 effectively protects the filter sleeve layer from mechanical damage while removing attachments and extending its service life. The lifting platform 351 and the rotating drive device 355 can be adjusted to meet the cleaning needs of the suction inner shaft 321 of different specifications and states.

[0053] See also Figure 1 , Fig. 9 , Fig.10 and Fig.11As shown, the reflux dehumidification device 4 includes a mounting track 41, an air flow channel 411 and a filter layer switching track 412 are arranged inside the mounting track 41, the air flow channel 411 is used to circulate hot air, the filter layer switching track 412 is connected to the air flow channel 411, a humidity detector is arranged in the mounting track 41, a filter layer winding switching device 44 is also installed on the mounting track 41, a quick-drying dehumidification filter layer 45 is installed on the filter layer winding switching device 44, the quick-drying dehumidification filter layer 45 passes through the mounting track 41, a pressing pipe 42 is installed on the air flow channel 411, and the reflux dehumidification device 4 also includes a first linear drive 65 for driving the pressing pipe 42 to move.

[0054] The suction pump extracts the hot and humid gas passing through the composite fabric 7 and sends it to the input end of the filter layer switching track 412 of the reflux dehumidification device 4 through a pipeline. The input end of the filter layer switching track 412 is connected to the output end of the suction pump. The filter layer switching track 412 transports the incoming hot and humid gas to the air flow channel 411 of the mounting track 41. After the hot and humid gas enters the air flow channel 411, it passes through the quick-drying dehumidification filter layer 45. In this process, the moisture in the gas is absorbed by the quick-drying dehumidification filter layer 45, and the dry hot gas continues to flow along the air flow channel 411. The humidity detector monitors the humidity of the passing gas in real time, and sends a signal when it detects that there is too much moisture in the quick-drying dehumidification filter layer 45. When the humidity detector sends a signal, the first linear drive 65 starts to drive the pressing pipeline 42 to release the pressing of the quick-drying dehumidification filter layer 45. At the same time, the filter layer winding switching device 44 starts to work, and the quick-drying dehumidification filter layer 45 that has absorbed a large amount of moisture is wound up, and switched to the next layer of dry quick-drying dehumidification filter layer 45. After the dry quick-drying dehumidification filter layer 45 moves to the filtering area, it continues to dehumidify the passing airflow. The dehumidified dry hot air continues to flow along the airflow channel 411 and enters the heating device 5 through the pressing pipe 42. The heating device 5 will reheat the gas. Effective dehumidification and recovery of gas.

The filter layer winding and switching device 44 also includes a winding mounting frame 442 at the lower end of the mounting track 41, and a winding shaft 4421 is arranged inside the winding mounting frame 442. A synchronous driving device is installed on the winding mounting frame 442, and the driving ends of the synchronous driving device are transmission-connected with the hot air circulation shaft 4411 and the winding shaft 4421.

[0056] The synchronous driving device includes a plurality of transmission gears 445 distributed on the hot air circulation shaft 4411 and the winding shaft 4421 , and a transmission chain 446 is sleeved on the transmission gears 445 . The synchronous driving device also includes a rotary driver 444 for driving the winding shaft 4421 to rotate.

[0057] The quick-drying and dehumidifying filter layer 45 is pre-wound on the reel 4421 and is in a state of being ready for use. The hot air circulation shaft 4411 is located at the upper end of the mounting track 41, and a self-rotating airflow fan 443 is installed at its air inlet end to assist air drying. The synchronous drive device transmits the power of the rotary driver 444 to the hot air circulation shaft 4411 and the reel 4421 through the transmission gear 445 and the transmission chain 446 to ensure that the two rotate synchronously. The suction pump sends the hot and humid gas passing through the composite fabric 7 into the hot air circulation shaft 4411 of the reflux dehumidification device 4, and the hot air circulation shaft 4411 guides the airflow into the airflow channel 411. In the airflow channel 411, the hot air flows through the quick-drying and dehumidifying filter layer 45, the moisture is absorbed, and the dry hot air continues to flow along the airflow channel 411. The humidity detector monitors the gas humidity in real time, and when it is found that the quick-drying and dehumidifying filter layer 45 is saturated, a signal is sent to start the switching program. The first linear drive 65 responds to the signal and drives the pressing pipe 42 to release the pressing on the current quick-drying dehumidification filter layer 45 in preparation for winding up. The synchronous drive device starts and drives the hot air circulation shaft 4411 and the winding shaft 4421 to rotate synchronously. The winding shaft 4421 releases the wet quick-drying dehumidification filter layer 45, while the hot air circulation shaft 4411 receives and wraps around these wet quick-drying dehumidification. When the wet quick-drying dehumidification filter layer 45 is completely wound onto the hot air circulation shaft 4411, the synchronous drive device continues to rotate and pulls the next layer of dry quick-drying dehumidification filter layer 45 to the filtration area to take over the dehumidification work. After the new filter layer is in place, the passing airflow continues to be dehumidified to maintain the efficient operation of the drying device.

[0058] When hot air enters from the air inlet end of the air flow shaft, it heats the outer wall of the air flow shaft, and the heated outer wall can heat the wet quick-drying dehumidification filter layer 45, while the hot air passes through the gas flow hole 4431 of the self-rotating air flow fan 443. The airflow drives the driving blade to rotate, and then drives the self-rotating air flow fan 443 to rotate, generating an outward airflow. This airflow blows to the outside of the hot air flow shaft 4411, and air-dries the wound quick-drying dehumidification filter layer 45, accelerating its drying process. The design of the device not only realizes the automatic switching of the quick-drying dehumidification filter layer 45, but also realizes the rapid air drying of the wet filter layer through the combination of the hot air flow shaft 4411 and the self-rotating air flow fan 443, which is convenient for repeated use, and ensures the continuity and stability of the dehumidification effect.

[0059] See also Fig. 9 and Fig.12As shown, the outer wall of the quick-drying and dehumidifying filter layer 45 is provided with a water vapor adsorption layer 451 , and the wall thickness of the quick-drying and dehumidifying filter layer 45 is provided with dehumidification circulation holes 452 .

[0060] The design of the quick-drying dehumidification filter layer 45 fully considers the dehumidification efficiency and reusability. The outer wall of the filter layer is provided with a water vapor adsorption layer 451, which is made of a highly efficient water-absorbing material and can quickly absorb and lock the moisture in the passing airflow. At the same time, a plurality of dehumidification circulation holes 452 are provided in the wall thickness of the filter layer. These holes provide a smooth passage for the airflow and increase the contact area between the airflow and the water vapor adsorption layer 451, so as to improve the quick-drying effect of the water vapor adsorption layer 451 and facilitate recycling.

[0061] See also Figure 1 and Figure 4 As shown, the synchronous clamping device 6 includes a fixed frame 61 installed on the drying box 1, a plurality of sliding mounting frames 62 are installed on the fixed frame 61, and each of the sliding mounting frames 62 is provided with an inclined slide rail 621. A second linear drive 43 is also installed on the fixed frame 61, and a mobile connecting frame 63 is installed at the output end of the second linear drive 43. A sliding connecting shaft 64 is installed on the mobile connecting frame 63, and the sliding connecting shaft 64 is slidably connected to the inclined slide rail 621.

[0062] When the composite fabric 7 is fed into the drying box 1 through the inlet, the second linear drive 43 is activated. Its output end pushes the mobile connecting frame 63 to move along the preset track on the fixed frame 61. The sliding connecting shaft 64 installed on the mobile connecting frame 63 is closely matched with the inclined slide rail 621 on the sliding mounting frame 62 to achieve smooth sliding of the sliding connecting frame. The bonding spraying device 2 and the bonding suction device 3 can adjust their positions synchronously with the movement of the mobile connecting frame 63, so as to achieve accurate clamping of the composite fabric 7.

[0063] Due to the sliding connection design of the sliding connection shaft 64 and the inclined slide rail 621, and the precise control of the second linear drive 43, the bonding spray device 2 and the bonding suction device 3 are highly synchronized during the clamping process. This synchronization not only ensures the stability of the composite fabric 7 during the drying process, but also avoids fabric damage or uneven drying caused by device misalignment. According to the width, thickness and other characteristics of the composite fabric 7, the synchronous clamping device 6 can adapt to composite fabrics 7 of different specifications by adjusting the position of the sliding mounting frame 62 on the fixed frame 61 and adjusting the output stroke of the second linear drive 43. This flexibility enables the drying device to be widely used in the drying process of various composite fabrics 7.

[0064] A drying method of a drying device for composite fabric production, comprising the following steps;

[0065] S1, feeding the composite fabric 7 to be dried through the entrance of the drying box 1, ensuring that the fabric is placed flatly at the preset starting position, starting the synchronous clamping device 6, and preparing to perform the clamping operation of the composite fabric 7;

[0066] S2, the synchronous clamping device 6 is started, and the laminating spraying device 2 and the laminating suction device 3 are precisely controlled to synchronously move to the two sides of the composite fabric 7, and the working ends of the two are opposite to each other and accurately clamp the composite fabric 7 between them, so as to ensure that the composite fabric 7 maintains stability and consistency during the drying process and prevents deviation or wrinkles;

[0067] S3, the laminating spraying device 2 starts to work, spraying the heated gas preheated by the heating device 5 to the bottom of the composite fabric 7, and the heated gas tightly and evenly covers the surface of the composite fabric 7, using the high temperature to accelerate the evaporation of water on the surface and inside of the composite fabric 7, thereby improving the heat transfer efficiency and making the dehumidification process faster;

[0068] S4. At the same time, the laminating suction device 3 is started to form a strong negative pressure area above the composite fabric 7, which quickly sucks up the hot and humid gas that passes through the composite fabric 7, ensuring that the moisture is effectively removed to avoid negative impact on the drying effect of the composite fabric 7;

[0069] S5. The sucked hot and humid gas enters the reflux dehumidification device 4, and is effectively filtered to recover the moisture in the gas while keeping the temperature of the gas as much as possible. Although the temperature of the gas after dehumidification has dropped, it still maintains a relatively high temperature, and then enters the heating device 5 for reheating. The heating device 5 adjusts the gas temperature according to actual needs to ensure that the temperature of the gas sprayed onto the composite fabric 7 again is appropriate. The above steps form a closed circulation system, and the heated gas is continuously sprayed on the composite fabric 7 to accelerate the evaporation of moisture, while the suction device continuously extracts, dehumidifies and reheats the hot and humid gas, and reuses it in the drying process.

[0070] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
