Description

Technical Field

[0001] This invention relates to the field of curtain cleaning technology, specifically to an automatic curtain cleaning and drying machine. Background Technology

[0002] For a long time, curtain cleaning has mainly relied on two traditional models: home cleaning and professional dry cleaning. Both suffer from inherent drawbacks of fragmented processes and disjointed steps. In a home setting, cleaning curtains involves a complete process: disassembling the curtains, moving them to the cleaning area, hand wiping / machine washing, air drying, and reinstalling them. Each step requires independent manual operation—disassembly requires climbing to remove the curtain hooks, moving them involves dealing with the weight of the heavy curtains, air drying requires a lot of space and is affected by the weather, and reinstallation requires precise alignment with the hanging rod. The entire process is time-consuming and labor-intensive, often taking 1-2 days to clean the curtains of an average apartment. While the dry cleaning model eliminates the need for home cleaning, it still suffers from fragmentation. Users must pack the disassembled curtains and deliver them to the store, where they are then sorted, stored, and queued for cleaning. After cleaning, users must return to pick up the curtains and reinstall them themselves. The entire cycle typically takes 3-7 days, and the multiple transfers in between increase curtain management costs.

[0003] The core pain points of traditional decentralized cleaning models lie in two dimensions: efficiency and waste. In terms of efficiency, household manual cleaning is limited by manpower and tools, and cleaning a single set of curtains takes a long time and cannot handle multiple sets of curtains at the same time. Although dry cleaners have professional equipment, they are limited by the segmented operation process of "receiving-sorting-cleaning-drying-collection", which makes it impossible to achieve continuous production. The capacity of a single shift is usually only a few dozen sets, which is difficult to meet the large-scale curtain cleaning needs of hotels, office buildings, apartment buildings and other similar establishments. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an automatic curtain washing and drying all-in-one machine, which solves the problems of large curtains being difficult to wash at home using a washing machine or by hand, and the high cost and long time required to go to a dry cleaner.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automatic curtain washing and drying integrated machine, comprising a housing, wherein the housing is provided with a washing area, a drying area, and an air-drying area, which are separated by partitions. The washing area is provided with multiple sets of pressure rollers, multiple sets of brush rollers, and a spraying mechanism.

The active adjusting sprocket and the transmission sprocket are connected by a chain drive, and the transmission sprocket is fixedly connected to the upper surface of one of the drying steering sprockets.

[0009] Preferably, the spraying mechanism includes a pre-wetting nozzle, a detergent nozzle one, a detergent nozzle two, a clean water nozzle one, a clean water nozzle two, and a clean water nozzle three. The pre-wetting nozzle, detergent nozzle one, detergent nozzle two, clean water nozzle one, clean water nozzle two, and clean water nozzle three are all fixedly connected inside the cleaning zone, and the pressure roller group and the brush roller group are rotatably connected inside the cleaning zone.

[0010] Preferably, the arrangement of the pressure roller group, brush roller group, and spraying mechanism is as follows: the pre-wetting nozzle is located near the cleaning inlet, followed by a pressure roller group, a detergent spray head one, a brush roller group, a pressure roller group, a detergent spray head two, a brush roller group, a pressure roller group, a clean water spray head one, a brush roller group, a pressure roller group, a clean water spray head two, a brush roller group, and a clean water spray head three. The pressure roller group, brush roller group, and spraying mechanism are arranged in sequence from the cleaning inlet to the drying inlet.

[0011] Preferably, the passive brush roller assembly and the air knife assembly are located on both sides of the curtain, the air duct assembly is arranged in an N-shape along the transmission direction of chain three, and the outer wall of the air duct assembly has multiple sets of openings, all of which face the curtain.

[0012] Preferably, a first pad and a second pad are provided on the lower side of the fixed plate in the open area, and the first pad and the second pad are respectively close to the washing inlet and the drying outlet.

[0013] Preferably, each of the pressure roller groups has an output sprocket two fixedly connected to its top end. The output sprocket two is connected to a chain one. The chain one is connected in series with the output sprocket two, the auxiliary sprocket one, and the active adjustment sprocket two. The active adjustment sprocket two is fixedly connected to the outer wall of the air-drying steering sprocket. The auxiliary sprocket one is rotatably connected to the inside of the housing.

[0014] Preferably, each of the brush roller groups is fixedly connected to an output sprocket one, the output sprocket one is connected to a chain two, the chain two is connected in series with the output sprocket one, the active adjustment sprocket three and the auxiliary sprocket two, the active adjustment sprocket three is fixedly connected to a speed regulating motor, the speed regulating motor is fixedly connected to the lower surface of the housing on the fixed plate in the open area, and the auxiliary sprocket two is rotatably connected inside the housing.

[0015] Working principle: First, in the open curtain hanging area, the operator neatly arranges the curtains to be washed for the same customer on the double-bar platform, and hangs the upper hooks of the curtains one by one on the oval hanging rings below the conveyor chain. After starting the equipment, the speed-regulating motor drives the chain to run along the closed-loop guide rail, smoothly moving the curtains into the cleaning area inside the chamber.

[0016] Upon entering the cleaning area, the curtains undergo a fully automatic cleaning process: first, pre-wetting nozzles spray clean water on both sides; then, they are squeezed by pressure rollers and sprayed with detergent; next, high-speed rotating soft-bristled brush rollers perform deep cleaning; finally, they are rinsed three times by multiple sets of clean water nozzles, with the pressure rollers draining water and the brushes cleaning alternately during the process. All spraying and brushing actions are automatically started and stopped by light-controlled switches and solenoid valves, achieving precise cleaning.

[0017] After washing, the curtains are transferred to the draining area, where they pass through a combination of vertically positioned air knives and passive brush rollers. The air knives blow out high-pressure airflow, which, combined with the rotating brush rollers, effectively removes a large amount of moisture from the surface of the curtains. The curtains then enter the drying area, traveling nearly 10 meters along a pre-set N-shaped guide rail on the top of the drying chamber. Four perforated hot air pipes continuously blow hot air onto both sides of the curtains, achieving uniform and efficient drying.

[0018] Finally, the dried curtains are moved out of the cabinet by a chain and returned to the open curtain collection area. Operators remove the curtains from the hanging rings and neatly stack them on the double-bar curtain collection platform until all the customer's curtains have been collected. The entire process requires no manual handling or transfer, achieving fully automated continuous operation from hanging, washing, dehydrating, drying to curtain collection.

[0019] This invention provides an automatic curtain washing and drying machine. It has the following beneficial effects:

[0020] 1. This invention, through its open operating area and closed functional area structure, seamlessly connects the washing area, air-drying area, and drying area using a closed-loop conveyor mechanism. The entire process of hanging, washing, dehydrating, drying, and removing curtains requires no manual transfer, thus changing the traditional decentralized cleaning model. This significantly improves operational efficiency while avoiding secondary pollution and damage during curtain transfer.

[0021] 2. The cleaning area of ​​this invention is scientifically arranged with six sets of nozzles of different functions, following the logic of pre-wetting - detergent spraying - multiple rinses with clean water. These nozzles, along with a light-controlled switch and a solenoid valve, enable automatic start and stop, ensuring even liquid coverage of both sides of the curtains. Alternating sets of pressure rollers and brush rollers are used. The pressure rollers rotate in sync with the curtains, preventing deformation and assisting in cleaning. The brush rollers rotate 2-3 times faster than the curtains, efficiently removing stains. Furthermore, the hard pressure rollers and soft polyester fiber bristles ensure thorough cleaning while avoiding damage to thin curtain materials.

[0022] 3. The drying zone of this invention employs a combination of air blades and passive brush rollers. High-pressure airflow works in conjunction with the brush rollers that rotate synchronously with the curtains, saving energy for subsequent drying. The drying zone extends the curtain travel distance through an N-shaped guide rail layout, with symmetrically arranged air ducts at the top and bottom. Small directional round holes are opened in the duct walls, ensuring that hot air can evenly cover both sides of the curtains, preventing localized dampness or excessive drying. This process design, which involves dehydration followed by drying, significantly reduces energy consumption and eliminates the need for forceful wringing, preventing the curtains from deforming or wrinkling after drying, thus eliminating the need for additional ironing.

[0023] 4. The two sets of pads in the open area of ​​this invention allow curtains from the same customer to be stacked together. The curtain straps are secured above the double bars, eliminating the need for handling and sorting when hanging or removing curtains. The chain of the conveyor mechanism has an oval hanging ring fixed under the single-sided curved plate, facilitating quick hooking and unhooking of curtains. The operator only needs to complete two simple steps: hooking and unhooking, which reduces physical exertion and ensures that the customer's curtains are not mixed up. Attached Figure Description

[0033] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see the appendix Figure 1 -Appendix Figure 5 This invention provides an automatic curtain washing and drying machine, including a housing 1. The housing 1 has a washing zone 2, a drying zone 3, and an air-drying zone 4 inside. The washing zone 2, drying zone 3, and air-drying zone 4 are separated by partitions. The washing zone 2 has multiple sets of pressure rollers 6, multiple sets of brush rollers 7, and a spraying mechanism 8 inside. An open area fixing plate 18 is fixedly connected to the outer wall of the housing 1. The housing 1 and the open area fixing plate 18 are connected to a conveying mechanism 5. The washing zone 2 has a washing inlet 21. The drying zone 3 has a drying outlet 22. The air-drying zone 4 has an air-drying outlet 24 and an air-drying inlet 23. At least one set of passive brush rollers 15 and an air knife 16 are fixedly connected inside the air-drying zone 4. An air duct 17 is fixedly connected inside the drying zone 3. A hanging pipe 28 is fixedly connected to the lower surface of the open area fixing plate 18.

[0035] Specifically, the cabinet 1 is made of high-strength steel structure, with an overall rectangular shape. Its internal dimensions are 4.5 meters long, 3 meters high, and 1.5 meters wide, providing ample working space for the entire curtain washing and drying process. The interior of cabinet 1 is functionally divided by rationally arranged partitions. Specifically, a left and right partition is placed 0.5 meters from the wide side of cabinet 1, extending to 0.5 meters from the other end. A horizontal partition is also placed at the same level as the middle partition, parallel to the side width, with an opening only below the guide rail for curtains to pass through. This partition design creates three relatively independent and functionally defined areas inside cabinet 1: washing area 2, drying area 3, and air-drying area 4. Each of the three areas has an inspection door on one outer wall for easy maintenance. The washing area 2 integrates multiple sets of pressure rollers 6, multiple sets of brush rollers 7, and a spray mechanism 8. These components work together to complete the curtain washing operation. An open area fixing plate 18 is fixedly connected to the outer wall of the housing 1. This fixing plate, together with the housing 1, supports and connects to the conveying mechanism 5, which provides power and guidance for the movement of the curtains between different areas. To ensure smooth entry and exit of the curtains between areas, the washing area 2 is equipped with a washing inlet 21, the drying area 3 is equipped with a drying outlet 22, and the air-drying area 4 is equipped with an air-drying outlet 24 and an air-drying inlet 23. The size of each inlet and outlet is adapted to the curtains' passage requirements to ensure unobstructed entry and exit. At least one set of passive brush rollers 15 and air knife 16 are fixedly connected inside the air-drying area 4. The two sets of components work together to dehydrate the curtains. An air duct 17 is fixedly connected inside the drying area 3. The air duct 17 is responsible for supplying hot air to the drying area 3 to achieve the drying operation of the curtains. The entire equipment has a compact and reasonable structural design, with clear division of labor among its components and areas. The hanging pipe 28 is equipped with two sets corresponding to the washing inlet 21 and the drying outlet 22 respectively. One set of hanging pipe 28 has two round pipes, and the curtain hook is inserted between the two round pipes, which makes it convenient to hang the curtain before washing and collect it after washing.

[0036] Please see the appendix Figure 6 The conveying mechanism 5 includes an inlet sprocket 501, an outlet sprocket 502, multiple air-drying steering sprockets 503, multiple drying steering sprockets 504, a chain 27, and a guide rail. The inlet sprocket 501 and the outlet sprocket 502 are rotatably connected to the lower surface of the open area fixed plate 18. The air-drying steering sprocket 503 is rotatably connected to the inside of the air-drying area 4. The drying steering sprocket 504 is rotatably connected to the inside of the drying area 3. Each single-sided curved plate of the chain 27 has a hanging ring fixedly connected to its lower surface.

[0037] Specifically, the conveying mechanism 5, serving as the core power and guiding structure for the movement of the curtains between different areas of the equipment, comprises an inlet sprocket 501, an outlet sprocket 502, multiple air-drying steering sprockets 503, multiple drying steering sprockets 504, chain 27, and guide rails. The inlet sprocket 501 and outlet sprocket 502 are rotatably connected to the lower surface of the open area fixing plate 18, corresponding to the positions of the washing inlet 21 and drying outlet 22 respectively, providing initial and final support for the closed-loop transmission of chain 27. The air-drying steering sprockets 503 are rotatably connected inside the air-drying zone 4, with two sprockets configured according to the spatial layout and transmission requirements of the air-drying zone 4, corresponding to the turning positions of the curtains entering and leaving the air-drying zone 4 respectively, ensuring smooth turning of the curtains within the air-drying zone 4. The drying steering sprockets 504 are rotatably connected inside the drying zone 3, with multiple sprockets configured according to the design requirements of the N-shaped transmission path in the drying zone 3, used to guide chain 27 to form an N-shaped transmission trajectory within the drying zone 3. Chain 3 27 is the core transmission component of the entire conveyor mechanism 5. Each of its single-sided curved plates has a fixed hanging ring on its lower surface, shaped like an oval about the size of a little finger. This design facilitates the hanging and unhooking of curtain hooks, improving operational convenience. The guide rails are set in the same direction as the transmission of chain 3 27. Part of the guide rail is installed on the top inner wall of housing 1, and part is installed below the n-shaped square tube below the fixed plate 18 in the open area. The guide rails on the top inner wall of housing 1 are arranged in an N-shape in the drying zone 3. The guide rails in the open area smoothly connect with the guide rails on the top inner wall of housing 1, forming a complete closed-loop guide rail. Chain 3 27 runs smoothly within the guide rails, ensuring that the curtains move at a uniform speed, thus guaranteeing precise operation in each process.

[0038] Please see the appendix Figure 6 The transmission method of the conveying mechanism 5 is as follows: Chain 3 27 is connected to the inlet sprocket 501 through the outlet sprocket 502. Chain 3 27 on the outer wall of the inlet sprocket 501 passes through the air drying inlet 23 and connects to the air drying steering sprocket 503 on one side for steering. Chain 3 27 is connected to the air drying steering sprockets 503 on both sides. Chain 3 27 passes through the outlet sprocket 502 on the other side and passes through the air drying outlet 24 to connect to the drying steering sprocket 504. Chain 3 27 and the drying steering sprocket 504 are set as N type. Chain 3 27 passes through the drying steering sprocket 504 and passes through the drying outlet 22 to connect to the outlet sprocket 502. Chain 3 27 completes closed-loop transmission. The guide rail is set along the transmission direction of chain 3 27.

[0039] Specifically, the conveying mechanism 5 ensures that the curtains can smoothly pass through each functional area in sequence to complete the entire process. The specific transmission path is as follows: Chain 3 27 forms an initial connection with the inlet sprocket 501 through the outlet sprocket 502. Chain 3 27 on the outer wall of the inlet sprocket 501 passes through the washing inlet 21 into the housing 1, and then passes through the drying inlet 23 to connect to the drying deflector sprocket 503 on one side. The first turn is achieved through the drying deflector sprocket 503, allowing the curtains to enter the drying area 4. Chain 3 27 connects to the drying deflector sprockets 503 on both sides in the drying area 4. Guided by the two drying deflector sprockets 503, the curtains complete the dehydration process in the drying area 4 and then exit from the drying outlet 24. Chain 3 27, exiting from the drying outlet 24, connects to the drying guide sprocket 504. Guided by multiple drying guide sprockets 504, chain 3 27 and the drying guide sprockets 504 cooperate to form an N-shaped transmission trajectory. This N-shaped layout effectively extends the travel distance of the curtains within the drying zone 3, ensuring drying effectiveness. After operating in the drying zone 3, chain 3 27 passes through the drying outlet 22 and connects to the outlet sprocket 502, thus completing a full closed-loop transmission. The guide rail is strictly set along the transmission direction of chain 3 27, providing guidance and support for the operation of chain 3 27 throughout the entire process. This ensures that chain 3 27 does not deviate or jam during transmission, thereby guaranteeing the smoothness and continuity of the curtains' movement between different areas, allowing for the orderly connection of the washing, dehydration, and drying processes.

[0040] Please see the appendix Figure 6 The conveying mechanism 5 also includes an active adjusting sprocket 505 and a transmission sprocket 506. The active adjusting sprocket 505 is fixedly connected to a speed regulating motor, which is fixedly connected to the outer wall of the housing 1. The active adjusting sprocket 505 and the transmission sprocket 506 are connected by a chain drive, and the transmission sprocket 506 is fixedly connected to the upper surface of one of the drying steering sprockets 504.

[0041] Specifically, the conveying mechanism 5 also includes an active adjusting sprocket 505 and a transmission sprocket 506. These two components ensure stable transmission and speed regulation of the conveying mechanism 5. The active adjusting sprocket 505 is fixedly connected to a speed-regulating motor, which is fixedly connected to the outer wall of the housing 1, specifically near the drying zone 3. This location facilitates connection and subsequent maintenance of the motor to the active adjusting sprocket 505. The active adjusting sprocket 505 and the transmission sprocket 506 are connected by a chain drive to ensure the stability and accuracy of power transmission. The transmission sprocket 506 is fixedly connected to the upper surface of one of the drying guide sprockets 504, and the two are coaxially fixed, allowing the rotation of the transmission sprocket 506 to directly drive the drying guide sprocket 504 to rotate synchronously, thereby providing power for the transmission of chain 3 27. The speed-regulating motor has an adjustable speed range. By adjusting the speed of the speed-regulating motor, the rotation speed of the active adjustment sprocket 505 can be changed. This speed is then transmitted to the drying guide sprocket 504 via the transmission sprocket 506, ultimately adjusting the transmission speed of the chain 27 to suit the washing and drying needs of curtains of different materials and thicknesses. Simultaneously, the active adjustment sprocket 505 also has the function of adjusting the tension of the chain 27. By adjusting the installation position of the active adjustment sprocket 505, the tension of the chain 27 can be effectively adjusted, preventing the chain 27 from becoming too loose or too tight during long-term operation, thus ensuring the smoothness of the transmission and the service life of the conveyor mechanism 5.

[0042] Please see the appendix Figure 5 The spraying mechanism 8 includes a pre-wetting nozzle 801, a detergent nozzle 1 802, a detergent nozzle 2 803, a clean water nozzle 1 804, a clean water nozzle 2 805, and a clean water nozzle 3 806. The pre-wetting nozzle 801, detergent nozzle 1 802, detergent nozzle 2 803, clean water nozzle 1 804, clean water nozzle 2 805, and clean water nozzle 3 806 are all fixedly connected inside the cleaning zone 2. The pressure roller group 6 and the brush roller group 7 are both rotatably connected inside the cleaning zone 2.

[0043] Specifically, the spray mechanism 8 is a key component for curtain cleaning. It includes a pre-wetting nozzle 801, a detergent nozzle 1 802, a detergent nozzle 2 803, a clean water nozzle 1 804, a clean water nozzle 2 805, and a clean water nozzle 3 806. These nozzles work together according to the different needs of the cleaning process to complete the curtain cleaning operation. All nozzles are fixedly connected inside the cleaning area 2, specifically on opposite sides of the cleaning area 2, arranged in a vertical straight line. Each group of nozzles consists of 8-12 nozzles connected in series. This arrangement ensures that the liquid sprayed from the nozzles evenly covers both sides of the curtains, guaranteeing a good cleaning effect. The spray mechanism 8 also incorporates a solenoid valve and a light-controlled switch for automatic control. The light-controlled switch can detect the position of the curtains in real time. When the curtains reach the corresponding nozzle area, the solenoid valve is automatically triggered to open, and the nozzles begin spraying liquid. When the curtains leave, the solenoid valve automatically closes, achieving efficient resource utilization. Both the pressure roller group 6 and the brush roller group 7 are rotatably connected inside the cleaning zone 2 via bearings. The roller body surface of the pressure roller group 6 has a gear-shaped structure; the roller body surface of the brush roller group 7 is provided with soft bristles made of polyester fiber, which is soft and elastic, and can avoid damaging the curtains while cleaning them. The two groups of components work together with the spray mechanism 8 to achieve deep cleaning of the curtains.

[0044] Please see the appendix Figure 5 The arrangement of the pressure roller group 6, the brush roller group 7, and the spraying mechanism 8 is as follows: the pre-wetting nozzle 801 is located near the cleaning inlet 21, followed by a group of pressure roller group 6, a group of detergent nozzle 1 802, a group of brush roller group 7, a group of pressure roller group 6, a group of detergent nozzle 2 803, a group of brush roller group 7, a group of pressure roller group 6, a group of clean water nozzle 1 804, a group of brush roller group 7, a group of pressure roller group 6, a group of clean water nozzle 2 805, a group of brush roller group 7, a group of clean water nozzle 3 806, and the pressure roller group 6, brush roller group 7, and spraying mechanism 8 are arranged in sequence from the cleaning inlet 21 to the drying inlet 23.

[0045] Specifically, the order in which the pressure roller group 6, the brush roller group 7, and the spray mechanism 8 are arranged in the cleaning area 2 strictly follows the logical flow of curtain cleaning, proceeding sequentially from the cleaning inlet 21 to the drying inlet 23, ensuring that the cleaning operation is carried out in an orderly and efficient manner. The pre-wetting nozzle 801 is located at the very front, closest to the cleaning inlet 21. The pre-wetting nozzle 801 first sprays clean water onto both sides of the curtains entering the cleaning area 2, achieving pre-wetting treatment and preparing them for subsequent cleaning. Following the pre-wetting nozzle 801, the following are arranged in sequence: a pressure roller group 6, a detergent spray head 1 802, a brush roller group 7, a pressure roller group 6, a detergent spray head 2 803, a brush roller group 7, a pressure roller group 6, a clean water spray head 1 804, a brush roller group 7, a pressure roller group 6, a clean water spray head 2 805, a brush roller group 7, and a clean water spray head 3 806. The spacing between adjacent components is set at 0.3 meters, which is adapted to the curtain's running speed, ensuring sufficient working time for each process. The rotation direction and speed of the pressure roller group 6 are completely consistent with the direction and speed of the curtain, mainly serving to compress the curtain to prevent deformation, assist in cleaning, and guide the curtain's movement. The rotation direction of the brush roller group 7 is consistent with the direction of the curtain, but its speed is much faster than the curtain's running speed. The high-speed rotating brush can effectively remove stains from the surface of the curtain. Detergent spray nozzles 1 (802) and 2 (803) spray detergent onto both sides of the curtain at different stages, ensuring that the detergent can fully cover and penetrate the stains. Water spray nozzles 1 (804), 2 (805), and 3 (806) rinse the curtain multiple times in sequence, gradually removing detergent and residual stains from the curtain, ultimately achieving a thorough cleaning of the curtain.

[0046] Please see the appendix Figure 5 The passive brush roller assembly 15 and the air knife assembly 16 are located on both sides of the curtain, and the air duct assembly 17 is arranged in an N-shape along the transmission direction of the chain 3 27. The outer wall of the air duct assembly 17 has multiple sets of openings, all of which face the curtain.

[0047] Specifically, the passive brush roller assembly 15 and the air knife assembly 16 within the drying zone 4 are the core components for dehydrating the curtains. They are located on either side of the curtain and correspond to its running path. The spacing between them is designed based on the thickness of common curtains to ensure smooth passage while achieving good dehydration. The passive brush roller assembly 15 consists of a single roller with soft bristles on its surface. It rotates passively, driven by the curtain. When the curtain moves under the drive of the conveyor mechanism 5, it contacts the bristles of the passive brush roller assembly 15, causing the roller to rotate. During rotation, the bristles comb the curtain surface and assist in removing moisture. The air knife assembly 16 has a uniformly wide outlet and can blow out high-pressure airflow. Both the air knife assembly 16 and the passive brush roller assembly 15 are 2.95 meters long, matching the height of the curtain to ensure complete coverage of its entire width. The air duct assembly 17 in drying zone 3 is arranged in an N-shape along the N-shaped drive direction of chain 3 27. This layout perfectly matches the running trajectory of the curtains in drying zone 3, ensuring that the curtains are exposed to hot air throughout the entire drying process. There are four air duct assemblies 17, installed on both sides above the guide rail and at the bottom directly below the guide rail, symmetrically distributed vertically. The outer wall of the air duct assembly 17 has multiple sets of openings, with 20-30 small round holes per meter of air duct, each with a diameter of 0.5 cm. All openings face the curtains, some openings are perpendicular to the curtains, and some openings are slightly inclined towards the direction of curtain movement. This design ensures that hot air is evenly and comprehensively blown onto both sides of the curtains, quickly removing moisture from the curtains and achieving efficient drying.

[0048] Please see the appendix Figure 1 The lower side of the fixed plate 18 in the open area is provided with a pad 19 and a pad 20, which are close to the washing inlet 21 and the drying outlet 22, respectively.

[0049] Specifically, two support platforms, 19 and 20, are installed on the underside of the fixed plate 18 in the open area, providing a stable support platform for hanging, retrieving, and stacking curtains. Both platforms are uniformly designed with a length of 2 meters, a width of 0.5 meters, and a height of 1.5 meters, adapting to the working space of the open area and the size of the curtains. Platform 19 is located near the washing inlet 21 of the washing area 2, and platform 20 is located near the drying outlet 22 of the drying area 3. Both are 0.3 meters away from the fixed plate 18 in the open area, facilitating operation when hanging and retrieving curtains. Above each platform are two parallel circular tubes, 5 centimeters in diameter, resembling double bars. The distance between the two tubes is adjustable within the range of 6-10 centimeters, achieved through adjusting bolts at both ends, accommodating curtains of different widths. When hanging curtains, the operator can neatly arrange curtains from the same customer to be washed in a single line between the two tubes of the drying platform 19, with the curtain straps secured above the tubes to prevent curtains from different customers from getting mixed up. When removing curtains, the operator unloads each curtain from the drying outlet 22 and neatly stacks them between the two tubes of the drying platform 20, continuing this process until all curtains from the same customer have been removed. This design not only significantly reduces the operator's workload but also effectively prevents curtains from getting mixed up, improving operational efficiency and service quality.

[0050] Please see the appendix Figure 7 The top of each pressure roller group 6 is fixedly connected to an output sprocket 2 10. The output sprocket 2 10 is connected to a chain 1 25. The chain 1 25 is connected in series with the output sprocket 2 10, the auxiliary sprocket 1 12, and the active adjustment sprocket 2 11. The active adjustment sprocket 2 11 is fixedly connected to the outer wall of the air drying steering sprocket 503, and the auxiliary sprocket 1 12 is rotatably connected to the inside of the housing 1.

[0051] Specifically, each pressure roller group 6 has an output sprocket 2 10 fixedly connected to its top. The output sprocket 2 10 is coaxially fixed with the roller body of the pressure roller group 6, ensuring that the output sprocket 2 10 can rotate synchronously with the pressure roller group 6. The output sprocket 2 10 is connected to a chain 25. The chain 25 connects all the output sprockets 2 10 of the pressure roller group 6, the auxiliary sprocket 1 12, and the active adjusting sprocket 2 11 in series to form a complete transmission system, ensuring that all pressure roller groups 6 can rotate synchronously. The auxiliary sprocket 1 12 is rotatably connected inside the housing 1, specifically installed above the inside of the cleaning area 2, and at the same height as the output sprocket 2 10. Its main function is to change the transmission direction of the chain 25 and assist in adjusting the tension of the chain 25 to ensure the smooth operation of the transmission system. Active adjusting sprocket 2 11 is fixedly connected to drying steering sprocket 503. The drying steering sprocket 503 drives the active adjusting sprocket 2 11 to rotate, which in turn transmits the rotational speed to all output sprockets 2 10 via chain 1 25, ultimately achieving synchronous adjustment of the rotational speed of all pressure roller groups 6. The rotational speed range of the pressure roller group 6 is typically designed to be 0.5-1 m / min, precisely matching the running speed of the curtains and ensuring that the pressure roller group 6 plays its optimal role in assisting cleaning and guiding the movement of the curtains.

[0052] Please see the appendix Figure 8 The top of each brush roller group 7 is fixedly connected to an output sprocket 1 9. The output sprocket 1 9 is connected to a chain 26. The chain 26 is connected in series with the output sprocket 1 9, the active adjustment sprocket 3 13, and the auxiliary sprocket 2 14. The active adjustment sprocket 3 13 is fixedly connected to a speed regulating motor. The speed regulating motor is fixedly connected to the lower surface of the housing 1 on the open area fixing plate 18. The auxiliary sprocket 2 14 is rotatably connected inside the housing 1.

[0053] Specifically, each brush roller assembly 7 has an output sprocket 9 fixedly connected to its top. The output sprocket 9 is coaxially fixed with the roller body of the brush roller assembly 7, ensuring that the rotation of the output sprocket 9 directly drives the brush roller assembly 7 to rotate synchronously. The output sprocket 9 is connected to a chain 26, which is made of the same material as chain 25. Chain 26 connects all the output sprockets 9 of the brush roller assembly 7 in series with the active adjusting sprocket 3 13 and the auxiliary sprocket 2 14, forming a complete transmission link, enabling all brush roller assemblies 7 to achieve unified speed regulation and synchronous rotation. The auxiliary sprocket 2 14 is rotatably connected inside the housing 1, and is rationally distributed according to the transmission path of chain 2 26, mainly serving to guide and adjust the tension of chain 2 26. The active adjusting sprocket 3 13 is fixedly connected to a speed-regulating motor, which is fixedly connected to the lower surface of the fixed plate 18 in the open area of ​​the housing 1. The installation position facilitates motor heat dissipation and subsequent inspection and maintenance. The speed-regulating motor has a wide speed adjustment range, which can meet the high-speed rotation requirements of the brush roller assembly 7. Its speed is set to be 2-3 times higher than the running speed of the curtains. The high-speed rotating brushes can deeply remove stains from the surface of the curtains, improving the cleaning effect. By adjusting the speed of this speed-regulating motor, the rotation speed of the active adjustment sprocket 3 13 can be changed, which is then transmitted to all output sprockets 1 9 through chain 2 26, realizing the synchronous adjustment of the speed of all brush roller assemblies 7 to adapt to the cleaning needs of curtains with different levels of stains and materials.
