Description

Technical Field

[0001] This invention relates to the field of intelligent drying equipment technology, specifically to a drying device and drying method for preparing cloud-feel fabrics. Background Technology

[0002] With the continuous improvement of people's living conditions and the pursuit of higher comfort, people have put forward higher requirements for the fabric and style of sleepwear, making the selection of fabric crucial. Currently, a cloud-feel sleep-aiding sleepwear fabric has been developed. This cloud-feel fabric exhibits excellent performance in terms of thermal and moisture comfort and contact comfort. It mainly adopts a large jacquard double or triple air-layer structure, with a loose fabric structure and soft hand feel. Finishing mainly addresses the issues of fabric shrinkage and wrinkling, with the main processes being drying and pre-shrinking.

[0003] During the drying process described above, a preliminary drying step involving stretching and shaping is first performed. Then, a secondary drying process is conducted using a drum dryer, during which steam is introduced. Steam causes the fibers to shrink significantly. After hot air drying, cold air is used to further release the fiber stress, resulting in minimal shrinkage after washing, thus meeting the requirements for garment application. However, the fabric surface after the secondary drying is significantly wrinkled and uneven. Therefore, the fabric undergoes a pre-shrinking process after the secondary drying to smooth the surface.

[0004] Currently, during the secondary drying process, workers must first manually pack the fabric into individual bags. This prevents tangling and friction between the fabrics, and also makes it easier to place the entire piece of fabric into the dryer. Furthermore, the divided fabric is more usable for subsequent applications. After the fabric is packed into its individual bags, workers place the bags into the drying drum, then start the drying process. The rotating drum humidifies, dries, and cools the fabric in the bags. This drying process is not only cumbersome but also requires a significant investment of manpower, which remains a challenge for those skilled in the art. Summary of the Invention

[0005] The purpose of this invention is to provide a drying device and drying method for preparing cloud-feel fabrics, so as to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a drying device for preparing cloud-feel fabric, comprising an outer box, a drying cylinder, a fan box, and a synchronization pipe; A control terminal is installed on the front surface of the outer casing. An alarm is installed on the top of the control terminal. A support ring is fixedly installed in the middle of the front surface of the outer casing. An exhaust box is passed through the bottom of the support ring. A filter box is connected through the bottom of the exhaust box. A temperature and humidity sensor is also installed at the connection between the exhaust box and the filter box. The drying cylinder is composed of a cylindrical plate and an air inlet plate. The surface of the air inlet plate is evenly provided with several airflow holes. Inside the drying cylinder, several baffles are arranged with the central axis as the center line. An isolation cavity is formed between every two baffles. A pressure plate is movably installed inside each isolation cavity. A support cylinder seat is provided at the rear end of the drying cylinder. The front end and rear end of the drying cylinder are rotatably connected to the support ring and the support cylinder seat, respectively. A drive unit is provided on one side of the lower part of the drying cylinder. A drive belt is connected between the output end of the drive unit and the outer wall of the drying cylinder. A refrigerant circulation system is provided at the lower part of the drying cylinder. The fan box is connected to the dry gas output end of the refrigerant circulation system. The air outlet end of the fan box is connected to an air supply box. The other end of the air supply box is connected to the inside of the support cylinder. The inside of the air supply box is connected to a steam pipe. The synchronizing pipe is fixedly connected to the middle of the drying cylinder along the central axis. Several auxiliary air holes are evenly opened on the non-contact surface between the synchronizing pipe and the partition. The open end of the synchronizing pipe passes through the air inlet plate. The inner wall of the open end of the synchronizing pipe is connected to an auxiliary air pipe through a bearing. An air pump is connected to the auxiliary air pipe. The air inlet end of the air pump is connected to a control valve through a pipe. The other end of the control valve is connected to the air outlet pipe of the fan box.

[0007] The present invention further describes a drying method for preparing cloud-like fabric, comprising: The first step is for the user to unpack the fabric from a continuous state into rolls, place each roll of fabric into the isolation chamber, close the chamber door, and set the operating parameters required for the drying process on the control terminal. The second step is to enter the steam humidification stage. On the one hand, the fabric is intermittently humidified by steam pipes, and on the other hand, the fan box and refrigerant circulation system are started. Steam mixed with heated dry gas enters the interior of the drying cylinder, and the drying cylinder runs at the humidification speed until the humidification time ends. The third step is to enter the stop-steam drying stage. The steam pipe stops steam humidification, while the fan box and refrigerant circulation system continue to run, and the temperature remains constant. The drying drum runs at the drying speed until the drying time ends. The fourth step is the natural heat dissipation stage. After the steam drying process is completed, the inside of the drying equipment drops to room temperature, the refrigerant circulation system is turned off, the fan box is running, and natural air dissipation is carried out inside. The drying drum runs at the heat dissipation speed until the heat dissipation time is over. After the heat dissipation is over, the drying equipment stops working, and the user takes out the fabric and performs the next operation.

[0008] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: The present invention adopts the setting of isolation chamber, pressure plate, temperature and humidity sensor and synchronization tube to isolate and divide the fabric in the drying cylinder. This not only eliminates the need for users to waste a lot of manpower to pack the fabric, but also allows the fabric to be dried in a relaxed and tension-free state. In addition, it realizes a multi-stage drying process and can intelligently adjust the drying process according to the actual drying effect, so that the internal stress of the fabric is fully released, effectively reducing and stabilizing its shrinkage rate.

Detailed Implementation

[0010] The following detailed, non-limiting description of the technical solution of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0011] Please see Figures 1 to 13 The present invention provides a technical solution: a drying device for preparing cloud-feel fabric. In this embodiment, one set is used as an example. It should be noted that when performing the batch drying process of fabric, the drying device is set up in multiple sets in a row. Specifically, it includes an outer box 1, with the side of the outer box 1 facing the user operation as the front side. A control terminal 3 is installed on the front surface of the outer box 1. The control terminal 3 is connected to the electrical components inside the drying device and is used to control and display the content of the drying process. An alarm is also installed on the top of the control terminal 3. When an abnormal phenomenon is detected inside the drying device, the alarm will perform an alarm operation to inform the user to perform a safety inspection of the equipment in time, so as to improve the safety of the equipment use.

[0012] See Figures 1 to 2 An air inlet is provided at the bottom of one side of the outer casing 1. An air inlet valve is provided at the air inlet to control the opening and closing of the air inlet. An air duct is also provided inside the outer casing 1. The air inlet is used to introduce gas from the external space into the outer casing 1. The air duct is used to ensure that the gas can flow out normally inside the outer casing 1 according to the set air duct direction. The air inlet and the air duct are conventional settings and are not shown in the figure. The interior of the outer box 1 is hollow. A support ring 2 is fixedly installed in the middle of the front surface of the outer box 1. The support ring 2 includes an outer ring that contacts the external space of the outer box 1 and an inner ring that contacts the internal space of the outer box 1. The outer ring of the support ring 2 is movably connected to the box door 4. When the box door 4 is engaged with the inner ring of the outer ring, it is in a sealed engagement state. One side of the box door is hinged to the front surface of the outer box 1. The inner ring is rotatably connected to the drying cylinder 5, so that the fabric is dried in a relaxed and tension-free state. This rotatable connection method includes, but is not limited to, bearing connection. The inner ring is used to support the front end of the drying cylinder 5. The user puts the fabric into the drying cylinder 5 by opening the box door 4. During the drying process, the box door 4 is sealed and engaged with the support ring 2.

[0013] Furthermore, the drying cylinder 5 is integrally formed by a cylindrical plate and an air inlet plate 6. The air inlet plate 6 is located at the rear end of the cylindrical plate, and several airflow holes are evenly distributed on the surface of the air inlet plate 6. The heated drying gas enters the interior of the drying cylinder 5 through these airflow holes to perform the drying process on the fabric. Inside the drying cylinder 5, several partitions 7 are arranged around the central axis, such as... Figure 6 As shown, a partition seat 21 is fixedly connected between the end of a partition 7 away from the central axis of the drying cylinder 5 and the inner wall of the drying cylinder 5 to support and fix the partition 7. Preferably, a plurality of flow holes are evenly opened on the surface of the partition 7 to further improve the flow of the drying air and expand the contact area between the air and the fabric to improve the drying efficiency. In addition, an isolation chamber 8 is formed between every two partitions 7. The interior of the isolation chamber 8 is used to isolate and place the divided fabric. Furthermore, its capacity is sufficient and it can remain fixed, thus replacing the use of the original cloth bag. Users can directly put the divided fabric into the corresponding isolation chamber 8. This saves the use of cloth bags and eliminates the need for users to waste a lot of manpower to pack the fabric and then put it into the drying cylinder 5. The isolation chamber 8 not only realizes the separate placement of the fabric and reduces the stacking and tangling between the fabrics, but also greatly improves the drying efficiency and drying effect of the fabric by utilizing the flow holes on the partitions 7 and the sufficient capacity of the isolation chamber 8.

[0014] In addition, the angle between each pair of partitions 7 determines the size of the space that the isolation cavity 8 can accommodate. The partitions 7 shown in this figure are evenly distributed, so the space size of the isolation cavity 8 is consistent.

[0015] See Figures 3 to 4The rear end of the drying cylinder 5 is rotatably connected to a support cylinder seat 13. This rotatable connection method includes, but is not limited to, bearing connection. The support cylinder seat 13 is used to stably support the rear end of the drying cylinder 5. A drive unit 15 is provided on the lower side of the drying cylinder 5. The fixed end of the drive unit 15 is fixedly installed inside the outer casing 1 through the frame. A transmission belt 14 is connected between the output end of the drive unit 15 and the outer wall of the drying cylinder 5. The output power of the drive unit 15 determines the rotation speed of the drying cylinder 5. When the drive unit 15 is started through the control terminal 3, the output end of the drive unit 15 drives the drying cylinder 5 to rotate at a corresponding speed through the transmission belt 14. The inner ring of the support ring 2 and the support cylinder seat 13 respectively provide stable support for the front and rear ends of the drying cylinder 5 in the stationary and rotating states.

[0016] See Figures 5 to 6 A refrigerant circulation system is installed below the drying cylinder 5 to assist in the airflow circulation heating and drying process. Specifically, the refrigerant circulation system includes a compressor 30, a gas drying chamber 33, a drying filter 35, and a gas-liquid separator 31. The compressor 30 is used to compress Freon refrigerant into a high-temperature, high-pressure gas. The gas drying chamber 33 includes a front chamber and a rear chamber that are connected to each other. An evaporator is installed inside the front chamber to absorb heat and cool the flowing airflow. Water vapor in the airflow forms condensate, and the gas achieves preliminary low-temperature drying. A condenser is installed inside the rear chamber to discharge heat. The flowing gas achieves high-temperature drying under the action of the discharged heat. The output end of the compressor 30 is connected to the input end of the condenser through a pipe. The output end of the compressor is connected to the input end of the dryer filter 35 through a pipe. The output end of the dryer filter 35 is connected to the capillary tube and then to the input end of the evaporator. The output end of the evaporator is connected to the input end of the gas-liquid separator 31 through a pipe. The output end of the gas-liquid separator 31 is connected to the input end of the compressor 30 through a pipe. The compressor 30 first compresses the refrigerant into a high-temperature, high-pressure gas and sends it to the condenser. Taking Freon as an example, the refrigerant in the condenser becomes a high-temperature liquid and releases heat to the outside. The refrigerant then passes through the dryer filter 35 and the capillary tube into the evaporator. After entering the evaporator, it absorbs heat and becomes a low-pressure gas. Then it returns to the compressor 30 through the gas-liquid separator 31, thus realizing the refrigerant circulation process. When the airflow or high-temperature humid airflow flows through the evaporator and condenser, the airflow completes low-temperature drying and high-temperature drying. When the airflow flows through the evaporator, the water vapor in it is heated and forms condensate that flows downward. The outer casing 1 is also equipped with a liquid collection tank 34. At the bottom of the gas drying box 33, corresponding to the position of the evaporator, a water pump is connected to the bottom of the gas drying box 33 through a pipe. The output end of the water pump is connected to the liquid collection tank 34. The liquid collection tank 34 has a built-in liquid level detector to monitor the internal water level and prevent overflow. The liquid collection tank 34 can be used to directly store liquid. Alternatively, the liquid collection tank 34 can be directly connected to a water tank for collecting condensate through a separate pipe. The water tank can be easily removed for condensate removal to prevent overflow. This will not be described in detail here.

[0017] Furthermore, a fan box 16 is connected to the rear end of the gas drying chamber 33. Preferably, a turbine fan is installed in the fan box 16. The air inlet of the fan box 16 is connected to the rear cavity where the condenser is located. The air outlet of the fan box 16 is connected to an air supply box 29. The other end of the air supply box 29 is connected to the interior of the support cylinder seat 13. When the refrigerant in the condenser becomes a high-temperature liquid and releases heat to the outside, the dry gas that was originally dehumidified by the evaporator is heated by the released heat and flows through the fan box 16, the air supply box 29 and the support cylinder seat 13. The heated dry gas finally enters the interior of the drying cylinder 5 through the airflow hole of the air inlet plate 6 and dries the fabric. When the drive unit 15 drives the drying cylinder 5 to rotate, the refrigerant circulation system can be started simultaneously, thereby realizing the heating and drying process of the fabric inside the cylinder.

[0018] A cooling fan 32 is provided on the front side of the compressor 30 to ensure that airflow can flow over the surface of the compressor 30 and remove its heat, so that it can operate normally.

[0019] Furthermore, the air supply box 29 is internally connected to a steam pipe 36, which is used to inject steam into the drying cylinder 5. It should be noted that after the cloud-feel fabric is placed in the cylinder, it needs to be intermittently humidified with steam for a period of time, then the steam is stopped for a period of time to dry, and finally it is naturally air-dried and cooled for a period of time, so as to fully release the internal stress of the fabric and reduce and stabilize its shrinkage rate. The steam pipe 36 is equipped with an electrically controlled valve to control the intermittent discharge of steam in the pipe. In addition, the input end of the steam pipe 36 is connected to an external steam generator, which is used to directly supply steam and is not used in conjunction with the relevant heating equipment inside the outer casing 1.

[0020] Further, see Figures 7 to 9A synchronizing pipe 12 is fixedly connected to the center of the drying cylinder 5 along the central axis. The synchronizing pipe 12 has a hollow internal structure, and the side of the synchronizing pipe 12 facing the support ring 2 is a closed end. The surface of the synchronizing pipe 12 is fixedly connected to the end of the partition plate 7 away from the partition plate seat 21, which further improves the support stability of the partition plate 7. Several auxiliary air holes 121 are evenly opened on the non-contact surface between the synchronizing pipe 12 and the partition plate 7. The several auxiliary air holes 121 face the isolation cavity 8 at their respective positions. The end of the synchronizing pipe 12 away from the closed end is set as an open end. The open end of the synchronizing pipe 12 passes through the air inlet plate 6, and a support member 20 is connected to its outer surface by a bearing. The support member 20 is fixedly supported. The synchronous tube 12 is supported inside the support cylinder 13 to effectively improve its support stability. The inner wall of the open end of the synchronous tube 12 is connected to an auxiliary air pipe 19 through a bearing. The auxiliary air pipe 19 is connected to a vacuum pump 17. The air inlet of the vacuum pump 17 is connected to a control valve 18 through a pipe. The other end of the control valve 18 is connected to the air outlet pipe of the fan box 16. When the vacuum pump 17 is started, some of the heated drying gas is directly sprayed out through the auxiliary air pipe 19 and the auxiliary air holes 121 in each isolation chamber 8, thereby effectively improving the drying effect of the fabric placed in each isolation chamber 8. This operation is an auxiliary option, and whether to activate the auxiliary option will be determined based on the actual drying effect.

[0021] Further, see Figures 11 to 12 Each isolation chamber 8 has a pressure plate 11 movably installed inside. The front and rear ends of the pressure plate 11 are respectively slidably connected to a support slide rod 9. The two ends of the support slide rod 9 are respectively fixedly connected to the synchronization pipe 12 and the drying cylinder 5. A support elastic body 10 is wound around the surface of the support slide rod 9. One end of the support elastic body 10 is fixedly connected to the pressure plate 11, and the other end of the support elastic body 10 is fixed to the end of the support slide rod 9 near the drying cylinder 5. In the initial state where the pressure plate 11 is not under force, the pressure plate 11 covers the outer surface of the auxiliary air hole 121 in the same isolation chamber 8. To avoid quality problems caused by direct blowing and snagging, the pressure plate 11 is set to effectively prevent the auxiliary air hole 121 from directly contacting the fabric in the corresponding isolation chamber 8, thus ensuring its quality. When the auxiliary air hole 121 sprays dry gas outward, the sprayed dry gas applies a centrifugal force to the pressure plate 11. The pressure plate 11 slides along the surface of the support slide bar 9, and the support elastic body 10 is compressed by the sliding action of the pressure plate 11. The dry gas is sprayed into the interior of the isolation chamber 8 through the auxiliary air hole 121 to achieve the drying process of the fabric. It should also be noted that the sliding distance of the pressure plate 11 along the surface of the support slide rod 9 is related to the airflow pressure and the position of the isolation cavity 8. For example, as shown in... Figure 12As shown, when drying gas is sprayed into the isolation chamber 8 located directly below the synchronization tube 12, the fabric will move away from the synchronization tube 12 and tend to gather at the bottom of the isolation chamber 8 at that position due to gravity and centrifugal force. At this time, the sliding distance of the pressure plate 11 is the maximum. Similarly, the sliding distance of the pressure plate 11 located directly above the synchronization tube 12 is the minimum. In addition, the pressure plates 11 at different positions can perform different degrees of light pressure on the fabric in the isolation chamber 8 by setting different sliding distances, thereby improving the relaxation of the fabric after drying in the isolation chamber 8.

[0022] Furthermore, an exhaust box 22 extends through the bottom of the support ring 2, and a filter box 23 is connected through the bottom of the exhaust box 22. A filter screen is installed inside the filter box 23 to filter out lint from the airflow. A temperature and humidity sensor is also installed at the connection between the exhaust box 22 and the filter box 23. The temperature and humidity sensor is connected to the control terminal 3 and displays the temperature and humidity data in real time. For example... Figure 6 As shown, a gas inflow space is left between the front end of the gas drying chamber 33 and the inner wall of the outer chamber 1, for the gas filtered by the filter chamber 23 or directly introduced by the air duct to flow in, thereby using the fan box 16 as a power source to perform the gas circulation process in the outer chamber 1; specifically, the filter chamber 23 is provided with an exhaust port one facing the inside of the outer chamber 1, and the filter chamber 23 is provided with an exhaust port two facing the outside of the outer chamber 1. An exhaust valve is provided at the exhaust port two. The exhaust port one is used to discharge the filtered gas into the inside of the outer chamber 1. Under the operation of the fan box 16, the filtered gas enters the inside of the gas drying chamber 33 through the gas inflow space, and the exhaust port two is used to discharge part of the filtered gas into the outside of the outer chamber 1 after the exhaust valve is opened. During the circulating drying of the fabric, the inlet valve and outlet valve are closed, and a heat pump-type closed circulation is formed inside the outer box 1. That is, the gas inside the outer box 1 is formed into an airflow in a certain airflow direction under the action of the fan box 16 and the refrigerant circulation system. Specifically, the airflow passes through the inside of the outer box 1, the gas inflow space, the gas drying box 33, the fan box 16, the support cylinder seat 13, the drying cylinder 5, the exhaust box 22, the exhaust port 1, and the inside of the outer box 1 in sequence to complete the closed circulation of the gas and complete the circulating drying of the fabric.

[0023] Further, see Figure 13A symmetrically arranged support sensing component is provided below the front end of the drying cylinder 5. A convex frame 24 is fixedly connected below the support sensing component. The convex frame 24 is fixedly supported on the inner bottom surface of the outer casing 1. Specifically, the support sensing component includes a support wheel 26. The support wheel 26 abuts against the cylinder wall of the drying cylinder 5. A concave frame is rotatably connected to the middle of the support wheel 26 through a shaft. A vibration damping support part 25 is fixedly connected to the bottom of the concave frame. The vibration damping support part 25 is set with reference to a vibration damping damper. The bottom of the vibration damping support part 25 is fixedly connected to the top of the convex frame 24. When the drying cylinder 5 is stationary, the support wheel 26 further applies support force to the cylinder wall of the drying cylinder 5 through the vibration damping support part 25 and the convex frame 24. When the drying cylinder 5 is rotating, the support wheel 26 improves the body stability of the drying cylinder 5 when rotating through the vibration damping effect of the vibration damping support part 25. Furthermore, two concave frames are positioned on the same horizontal line and a horizontal plate 27 is fixedly connected between the bottoms of the two concave frames. A pressure sensor 28 is installed between the bottom of the horizontal plate 27 and the convex frame 24. The pressure sensor 28 is connected to the control terminal 3 and transmits pressure data in real time. The control terminal 3 effectively judges the rotational stability of the drying cylinder 5 based on the pressure data. When an abnormality occurs in the drying cylinder 5, the alarm will be activated.

[0024] In this embodiment, when using the drying equipment for preparing cloud-feel fabric, the drying method is as follows: The first step is for the user to unravel the fabric from a continuous state into rolls, and place each roll of fabric into the isolation chamber 8 so that the fabric can be dried in a relaxed and tension-free state. After the fabric is placed, the door 4 is closed, and the operating parameters required for the drying process are set at the control terminal 3. The drying process includes a steam humidification stage, a stop-steam drying stage, and a natural heat dissipation stage. The operating parameters include at least the steam flow rate, steam discharge temperature, humidification speed and humidification time of the drying cylinder 5, drying speed and drying time of the drying cylinder 5, and heat dissipation speed and heat dissipation time of the drying cylinder 5.

[0025] The second step is to enter the steam humidification stage. On the one hand, the steam pipe 36 is used to intermittently humidify the fabric with steam. On the other hand, the fan box 16 and the refrigerant circulation system are started. Steam mixed with the heated dry gas enters the interior of the drying cylinder 5. The drying cylinder 5 runs at the humidification speed until the humidification time ends. Specifically, when the electrically controlled valve is opened and the fan box 16 is started, steam and heated dry gas intermittently humidify the fabric in the isolation chamber 8 through the air supply box 29 and the air inlet plate 6. The steam pipe 36 performs the intermittent humidification process by opening and closing the electrically controlled valve. For example, the temperature of the steam high-temperature humidification is set at 100°C. The output end of the drive unit 15 drives the drying cylinder 5 to rotate in both directions through the transmission belt 14. The total rotation time is set at 30 minutes, and the total rotation time is consistent with the humidification time. After the fabric is humidified at high temperature, the high-temperature humid air enters the gas drying chamber 33 through the exhaust box 22 and the filter box 23 according to the internal airflow circulation path. The evaporator inside the gas drying chamber 33 first condenses and cools the high-temperature humid air, turning it into low-temperature dry gas. The low-temperature dry gas is then condensed into heated dry gas by the condenser, and then mixed with the steam in the air supply box 29. The above process is repeated to complete the steam humidification process.

[0026] Furthermore, in the aforementioned steam humidification process, a temperature and humidity sensor monitors and displays the temperature and humidity data after the steam flows through the fabric in real time, which is recorded as the actual humidification temperature T. act and the actual humidification humidity RH act The user inputs the preset humidification temperature T in advance at the control terminal 3. pre and preset humidification humidity RH pre In the steam humidification process, the control terminal 3 monitors in real time whether the actual humidification temperature reaches the preset humidification temperature within the first specified time and whether the actual humidification humidity reaches the preset humidification humidity within the second specified time. For example, the first specified time is denoted as S1, and the second specified time is denoted as S2, wherein preferably 5min≤S1≤20min and 5min≤S2≤20min; When the actual humidification temperature T is monitored act The preset humidification temperature T was not reached within the first specified time S1. pre If the actual humidification temperature is temporarily below the set value, the steam generator connected to steam pipe 36 will increase the steam discharge temperature to help the actual humidification temperature of the fabric reach the preset humidification temperature as quickly as possible. After reaching the preset humidification temperature, the steam discharge temperature will return to the original set value. When the actual humidification temperature Tact has been detected to have reached the preset humidification temperature T within the first specified time S1, the steam discharge temperature will be adjusted accordingly. pre When the temperature reaches the set point, it indicates that the humidification temperature has been reached, and the steam will maintain its discharge temperature. When the actual humidification humidity (RH) is monitored act The preset humidification humidity (RH) was not reached within the second specified time S2. preIf the humidification humidity is temporarily insufficient, the steam generator connected to steam pipe 36 will increase the steam flow rate to help the fabric reach the preset humidification humidity as quickly as possible. After reaching the preset humidification humidity, the modified steam flow rate will be maintained until the high-temperature humidification process is completed. When the actual humidification humidity (RH) is detected... act The preset humidification humidity (RH) has been reached within the second specified time S2. pre When the humidity reaches the set level, the steam flow rate will be maintained. If the actual humidification temperature or the actual humidification humidity fails to reach the preset humidification temperature or humidity before the end of the steam humidification process, it indicates that the fabric has not been adequately humidified at high temperature and the internal stress of the fabric cannot be fully released in subsequent stages. Therefore, the alarm will be activated, the next stage will be paused, and the user will be notified to check the equipment in a timely manner.

[0027] When the actual humidification temperature and the preset humidification humidity both meet the standards before the steam humidification process ends, the next stage will begin.

[0028] The third step is to enter the drying stage after steaming stops; steam pipe 36 stops steam humidification, fan box 16 and refrigerant circulation system continue to run, temperature remains constant, and drying cylinder 5 runs at drying speed until the drying time ends. Specifically, when the fan box 16 is started, the heated drying gas follows the operating path of the steam humidification stage, and most of the gas remains in a circulating state to heat, dehumidify, and dry the fabric of the drying cylinder 5; for example, the output end of the drive unit 15 drives the drying cylinder 5 to rotate in both directions through the transmission belt 14, and the total rotation time is set to 60 minutes, which is consistent with the drying time.

[0029] During the drying phase after steaming stops, the temperature and humidity sensors continue to monitor and display the temperature and humidity data in real time, which is recorded as the actual drying temperature Td. act and actual dry humidity RHd act Similarly, the user inputs the preset drying temperature Td in advance at the control terminal 3. pre and preset dry humidity RHd pre For example, in the stop-steam drying process, the control terminal 3 monitors in real time whether the actual drying temperature reaches the preset drying temperature within the third specified time and whether the actual drying humidity reaches the preset drying humidity within the fourth specified time; the third specified time is recorded as S3, the second specified time is recorded as S4, preferably 0 < S3 ≤ 30 min, 0 < S4 ≤ 40 min, this range can be set according to actual production requirements, but cannot exceed 85% of the drying time, and the remaining time should be used to fully dry the moisture inside the fabric fibers under the condition that the temperature and humidity inside the drum meet the standards; Specifically, the judgment requirement is as follows: Control terminal 3 measures the actual drying temperature Td during the stop-drying stage using a temperature and humidity sensor. act The preset drying temperature Td was not reached within the third specified time S3. pre Or the actual dry humidity RHd act The preset dry humidity RHd was not reached within the fourth specified time S4. pre When the heating gas entering the drying cylinder 5 through the airflow hole fails to fully heat the fabric in the isolation chamber 8, it is necessary to improve the drying efficiency. Therefore, the control terminal 3 will start the air pump 17. Part of the heated drying gas is diverted at the air supply box 29 and sprayed directly through the auxiliary air pipe 19 and the auxiliary air hole 121 in each isolation chamber 8. Thus, the airflow hole and the auxiliary air hole 121 apply multi-directional heating gas to the fabric in the isolation chamber 8 to improve the drying efficiency of the fabric, thereby achieving full heating and drying of the fabric. In addition, the pressure plate 11 can also perform light pressure on the fabric in the isolation chamber 8 to varying degrees during this process, improving the relaxation of the fabric after drying, which is convenient for subsequent processing.

[0030] The fan box 16 can determine whether to increase the operating power based on the actual amount of fabric to be dried, so as to increase the flow rate of the circulating drying gas; the amount of fabric to be dried can be preset by the user at the control terminal 3.

[0031] The fourth step is the natural heat dissipation stage. After the steam drying process is completed, the inside of the drying equipment drops to room temperature, the refrigerant circulation system is shut down, the fan box 16 is running, and the inlet and outlet valves are opened. External natural air enters the outer box 1 through the inlet and air duct, mixes with the dry gas inside the outer box 1, and then enters the gas drying chamber 33, drying cylinder 5, and exhaust box 22 through the gas flow space. Both exhaust port 1 and exhaust port 2 are kept open. Some of the natural air with heat is discharged from exhaust port 2, and some is discharged from exhaust port 1 into the outer box 1 to mix with the newly entered natural air for natural air circulation and heat dissipation. The continuously entering natural air continuously dilutes and cools the original dry gas in the outer box 1 and carries it out, thereby allowing the interior of the outer box 1 to undergo natural air heat dissipation. The drying cylinder 5 runs at the heat dissipation speed until the heat dissipation time ends, so that the internal stress inside the fabric is completely released. Specifically, the output end of the drive unit 15 drives the drying cylinder 5 to rotate in both directions via the transmission belt 14. The total rotation time is set to 30 minutes, and the total rotation time is consistent with the heat dissipation time.

[0032] After the heat dissipation is complete, the drying equipment stops working, and the user can remove the fabric and proceed to the next step.

[0033] In addition, during the rotation of the drying cylinder 5, the pressure sensor 28 judges the vibration abnormality based on the measured pressure data. It judges whether there is a rotation abnormality by the fluctuation amplitude of the pressure data. For example, when the fluctuation amplitude is greater than the preset amplitude, it indicates that the rotation of the drying cylinder 5 is abnormal, the alarm will be activated, and the drying equipment will suspend the drying process to ensure that the drying process can be effectively performed and to ensure the safety of the equipment during operation.
