[0002] In the fabric production process, washing and drying equipment is an indispensable key device. Most existing fabric washing and drying devices use unidirectional hot air drying, which results in uneven heating of the fabric surface, leading to low drying efficiency, inconsistent drying levels, and negatively impacting the quality of subsequent processing. Furthermore, the fixed internal drying structure of existing devices makes it difficult to flexibly adjust to fabrics of different thicknesses and materials, resulting in poor applicability. In addition, insufficient sealing between drying pipes can easily cause hot air leakage, reducing energy efficiency and posing certain safety hazards. With the fabric manufacturing industry's increasing demands for product quality and production efficiency, developing a highly efficient, flexible, and well-sealed fabric washing and drying device has become an urgent problem to be solved.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a technical solution:

[0021] In this technical solution, a fabric washing and drying device includes a drying chamber 1. A conveyor roller frame 2 is mounted on the front side wall of the drying chamber 1, and a receiving roller frame 3 is mounted on the rear side wall of the drying chamber 1. A fabric conveying roller 4 is mounted on the conveyor roller frame 2, and a fabric receiving roller 7 is mounted on the receiving roller frame 3. A fabric conveying port 6 is provided through the side wall of the drying chamber 1. A fabric body 5 is wound around the outside of the fabric conveying roller 4, and the end of the fabric body 5 passes through the fabric conveying port 6 before being wound. Outside the fabric receiving roller 7, through holes 18 are provided on both the left and right side walls of the drying chamber 1. A U-shaped drying tube 11 is inserted into one through hole 18, and a straight drying tube 14 is inserted into the other through hole 18. The straight drying tube 14 is located at the lower end of the U-shaped drying tube 11, and the fabric body 5 is located between the straight drying tube 14 and the U-shaped drying tube 11. Electric push rods 15 are installed on both sides of the bottom end of the U-shaped drying tube 11, and the ends of the electric push rods 15 are connected to the straight drying tube 14.

[0022] The drying chamber 1 serves as the main frame of the entire device, providing installation and operating space for the internal structure. It can be made of 5mm thick stainless steel plate, offering excellent high-temperature and corrosion resistance. Its dimensions can be designed to be 2000mm long, 1200mm wide, and 1500mm high. The conveyor roller frame 2 and the receiving roller frame 3 are bolted to the side wall of the drying chamber 1. The distance between them can be adjusted according to actual production needs, generally between 1500-2000mm, ensuring that the fabric body 5 can be fully unfolded within the drying chamber 1. The fabric conveyor roller 4 and the fabric receiving roller 7 are both made of hollow steel pipe with an outer diameter of 100mm and an anti-slip surface. They are driven by a 1.5kW motor with a speed of 10-30r / min to achieve uniform conveying and receiving of the fabric body 5. The size of the fabric conveying port 6 is designed according to the width of the fabric body 5, and is usually 20-30mm larger than the width of the fabric to ensure that the fabric can pass through smoothly. A rubber sealing strip is set at the edge of the conveying port to prevent hot air from leaking out of the dryer box 1.

[0023] The system is equipped with a variable frequency speed control motor and a PLC control system. Sensors monitor the fabric's conveying speed and tension in real time, automatically adjusting the motor speed to ensure stable fabric conveying. Additionally, a fabric correction device can be added to prevent fabric deviation during conveying, which could affect drying performance.

[0024] The diameter of the through hole 18 is designed based on the outer diameter of the U-shaped drying tube 11 and the straight drying tube 14, and is generally 5-10mm larger than the tube diameter to ensure a certain degree of sealing after the drying tube is installed. A high-temperature resistant sealing ring can be set at the edge of the through hole 18. Both the U-shaped drying tube 11 and the straight drying tube 14 are made of seamless steel tubes with good thermal conductivity, a tube diameter of 50mm, a tube wall thickness of 3mm, and a high-temperature resistant anti-corrosion coating on their surface. The open end of the U-shaped drying tube 11 faces the fabric body 5, and the upper surface of the straight drying tube 14 also faces the fabric body 5. The initial distance between the two can be set to 100-200mm and adjusted by the electric push rod 15. The electric push rod 15 can be a DTZ-100 model with a stroke of 100mm and a thrust of 500N, which can realize the precise vertical movement of the straight drying tube 14 to adapt to the drying needs of fabrics of different thicknesses.

[0025] A support bracket can be installed inside the dryer chamber 1, and the drying tube can be fixed to the bracket with bolts to enhance the stability of the drying tube. Meanwhile, the hot air inlet and outlet settings for the drying tube are not mentioned. A hot air inlet can be installed at one end of the U-shaped drying tube 11, and a hot air outlet can be installed at one end of the straight drying tube 14 to ensure smooth flow of hot air within the drying tube.

[0026] In some technical solutions, a dryer 8 is installed at the top of the dryer box 1, and a converter 9 is installed at the output end of the dryer 8. The end of the U-shaped drying tube 11 is connected to the left side of the converter 9, and the other end of the converter 9 is equipped with an L-shaped drying tube 10. The L-shaped drying tube 10 is connected to the straight drying tube 14 through a connecting component 17.

[0027] Dryer 8 can be an industrial hot air circulating dryer, model HR-50, with a rated power of 30kW and a maximum temperature of 200℃, providing a stable hot air source. The adapter 9 is made of high-temperature and corrosion-resistant metal, possessing excellent sealing and connection strength. Its interface dimensions match the output end of dryer 8, the U-shaped drying pipe 11, and the L-shaped drying pipe 10. The material and diameter of the L-shaped drying pipe 10 are consistent with the U-shaped drying pipe 11 and the straight drying pipe 14. Its bending angle is 90°, and its length is designed according to the internal space of the dryer chamber 1 and the hot air delivery requirements, generally 500-800mm. The L-shaped drying pipe 10 is connected to the straight drying pipe 14 via the connecting assembly 17, forming a complete hot air delivery channel, ensuring that hot air can be evenly blown out from the drying port 13 to dry the fabric body 5.

[0028] A temperature sensor and flow control valve are added to monitor and adjust the hot air temperature and flow rate in real time, ensuring the stability of the drying effect. While the specific connection method for adapter 9 is not specified, a flange connection can be used, secured with bolts and fitted with a sealing gasket to ensure a tight and reliable connection.

[0029] In some technical solutions, the end of the straight drying tube 14 is provided with an opening 16, and the connecting assembly 17 includes a sealing cylinder 172 installed in the opening 16 and a telescopic tube 171 installed at the bottom of the L-shaped drying tube 10. The inner wall of the sealing cylinder 172 is provided with an internal thread 173, and the outer wall of the telescopic tube 171 is provided with an external thread 174. The internal thread 173 and the external thread 174 are matched.

[0030] The diameter of the opening 16 is 2-3 mm larger than the outer diameter of the sealing cylinder 172, ensuring that the sealing cylinder 172 can be tightly embedded into the end of the straight drying tube 14. The length of the sealing cylinder 172 is 80-100 mm, the pitch of the internal thread 173 is 2 mm, and the thread angle is 60°, providing good engagement performance. The length of the telescopic tube 171 can be designed according to actual needs, generally 100-150 mm, with a telescopic range of 30-50 mm. The external thread 174 matches the internal thread 173. By rotating the telescopic tube 171, the L-shaped drying tube 10 and the straight drying tube 14 can be quickly connected and disconnected. During installation, high-temperature resistant sealant can be applied to the threaded connection to further enhance the sealing performance.

[0031] In some technical solutions, the sealing cylinder 172 is provided with rubber pads a176 and b175 inside, and rubber pads a176 and b175 are sleeved on the outside of the telescopic tube 171. Rubber blocks 177 are evenly and equidistantly installed at the edges between rubber pads a176 and b175.

[0032] Both rubber gaskets A176 and B175 are made of high-temperature resistant and aging-resistant silicone rubber, with a thickness of 5mm. Their inner diameter matches the outer diameter of the telescopic tube 171, and their outer diameter matches the inner diameter of the sealing cylinder 172, allowing them to fit tightly against the inner walls of both tubes. Rubber block 177 has a height of 10mm and a width of 8mm, made of the same material as the rubber gaskets, and is evenly distributed between rubber gaskets A176 and B175, forming a multi-layered sealing structure to effectively prevent hot air leakage. During installation, rubber gasket A176 is positioned closer to the straight drying tube 14, and rubber gasket B175 is positioned closer to the L-shaped drying tube 10, further enhancing the sealing effect.

[0033] A removable end cap can be provided at the end of the sealing cylinder 172 to facilitate regular inspection and replacement of the rubber gasket and rubber block. At the same time, an anti-stick coating can be applied to the surface of the rubber gasket and rubber block to prevent them from sticking to the telescopic tube 171 at high temperatures, thereby improving the convenience of maintenance.

[0034] In some technical solutions, drying ports 13 are provided at the top of the straight drying tube 14 and the bottom of the U-shaped drying tube 11.

[0035] The drying port 13 is elongated, with a length matching the drying tube and a width of 10-15 mm. Its edges are rounded to prevent scratching the fabric body 5. A guide plate with a 45° angle is installed inside the drying port 13 to ensure even distribution of hot air to the fabric body 5, improving drying efficiency. The number of drying ports 13 can be determined based on the length of the drying tube and hot air requirements; generally, one drying port 13 is installed every 200-300 mm to ensure the fabric body 5 is adequately heated.

[0036] A protective net can be installed on the outside of the drying port 13 to prevent debris from entering the drying pipe and affecting the flow of hot air and the drying effect. At the same time, an adjustment device, such as an adjustable louver structure, can be added to the drying port 13 to adjust the blowing angle and flow rate of hot air according to the material and thickness of the fabric.

[0037] In some technical solutions, a vent 12 is provided at the top of the drying chamber 1.

[0038] The vent 12 is circular or square in shape, and its area is designed according to the internal space and ventilation requirements of the drying chamber 1, generally 0.1-0.2㎡. An axial flow fan, model T35-11, with an air volume of 3000-5000m³ / h, is installed at the vent 12 to force out the hot and humid air inside the drying chamber 1, ensuring air circulation and maintaining a stable temperature inside the chamber. Simultaneously, a filter screen is installed on the outside of the vent 12 to filter dust and impurities in the air, preventing them from entering the drying chamber 1 and contaminating the fabric body 5.

[0039] A temperature and humidity sensor can be added to monitor the temperature and humidity inside the drying chamber 1 in real time. When the temperature and humidity exceed the set range, the axial flow fan will automatically start to ventilate and ensure the stability of the drying environment. In addition, an opening and closing adjustment device for the air vent 12, such as an electric louver, can be installed to adjust the air volume according to different stages of the drying process.

[0040] I. Fabric Conveying Process and Principle

[0041] The fabric body 5 is initially wound around the fabric conveying roller 4. After the equipment is started, the variable frequency speed control motor drives the fabric conveying roller 4 to rotate at a speed of 10-30 r / min. Under the power of the motor, the fabric body 5 begins to move forward along the conveying direction. At the same time, the fabric collecting roller 7 rotates synchronously under the drive of another motor to collect the fabric body 5.

[0042] During the fabric conveying process, tension sensors installed near the fabric conveying roller 4 and the fabric collecting roller 7 monitor the fabric tension in real time. When the tension changes, the sensor transmits a signal to the PLC control system. The PLC control system automatically adjusts the speed of the variable frequency speed control motor according to preset parameters to ensure that the fabric body 5 is conveyed at a stable speed and with appropriate tension, avoiding fabric slack or breakage. In addition, the fabric correction device detects the fabric position in real time through photoelectric sensors. Once fabric deviation is detected, the correction mechanism is immediately activated to adjust the fabric, ensuring accurate conveying path of the fabric in the drying chamber 1 and providing stable conditions for the subsequent drying process.

[0043] II. Hot air generation and transmission process and principle

[0044] After the dryer 8 (model HR-50, rated power 30kW, maximum temperature up to 200℃) is started, the internal heating element starts working, heating the air to form hot air. The hot air enters the converter 9 through the output end of the dryer 8. The converter 9 adopts a flange connection, which is fixed with bolts and equipped with a sealing gasket to ensure that the hot air will not leak from the connection.

[0045] Hot air is split at the converter 9, with one part entering the U-shaped drying tube 11 and the other part entering the L-shaped drying tube 10. The U-shaped drying tube 11 and the L-shaped drying tube 10 are connected to the straight drying tube 14 via the connecting assembly 17. In the connecting assembly 17, the telescopic tube 171 (length 100-150mm, telescopic range 30-50mm) is telescopically extended and retracted via a spring telescopic structure. Its outer thread 174 engages with the inner thread 173 of the sealing cylinder 172 (length 80-100mm). High-temperature resistant sealant is applied to the threaded connection. At the same time, the rubber gaskets a176, b175, and rubber block 177 inside the sealing cylinder 172 form a multiple seal to ensure that the hot air does not leak during transportation. The hot air passes through the U-shaped drying tube 11, the L-shaped drying tube 10, and the straight drying tube 14 in sequence. During the flow inside the tubes, it is evenly blown out through the drying port 13 opened on the drying tube.

[0046] III. Fabric Drying Process and Principle

[0047] After the fabric body 5 enters the dryer chamber 1, it is positioned between the U-shaped drying tube 11 and the straight drying tube 14. The open end of the U-shaped drying tube 11 and the upper surface of the straight drying tube 14 both face the fabric body 5, with an initial distance of 100-200mm between them. This distance can be adjusted by the electric push rod 15 (model DTZ-100, stroke 100mm, thrust 500N). For fabrics of different thicknesses, the electric push rod 15 adjusts the position of the straight drying tube 14 according to the control system commands, maintaining a suitable distance between the drying tube and the fabric to ensure that the hot air can effectively act on the fabric.

[0048] Hot air blown from drying port 13 (long and narrow, the same length as the drying pipe, 10-15mm wide, with a 45° baffle inside) is evenly directed onto the upper and lower surfaces of the fabric body 5 by the baffle, achieving double-sided drying. The hot air makes full contact with the fabric, removing moisture and achieving rapid drying. Drying ports 13 are spaced 200-300mm apart, and a protective net is installed on the outside to prevent debris from entering. The blowing angle and flow rate of the hot air can be adjusted by regulating the louver structure to accommodate the drying needs of different fabric materials.

[0049] IV. Ventilation Process and Principle

[0050] During the drying process, a large amount of hot and humid air is generated inside the dryer chamber 1. At this time, the axial flow fan (model T35-11, air volume 3000-5000 m³ / h) installed at the vent 12 starts, forcibly expelling the hot and humid air from the dryer chamber 1. The filter screen installed on the outside of the vent 12 effectively filters dust and impurities in the air, preventing them from entering the dryer chamber 1 and contaminating the fabric.

[0051] Meanwhile, a temperature and humidity sensor installed near the vent 12 monitors the temperature and humidity inside the drying chamber 1 in real time. When the temperature and humidity exceed the set range, the sensor transmits a signal to the control system, which automatically adjusts the speed of the axial fan to accelerate ventilation; or controls the opening and closing of the electric louvers of the vent 12 to adjust the ventilation volume and maintain the stability of the temperature and humidity inside the drying chamber 1, providing a good environmental condition for fabric drying.
