[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Reference Figure 1-6 A fabric washing machine includes a frame 1, three partitions 2 are arranged in parallel on the inner side of the frame 1, a washing chamber is formed between two adjacent partitions 2, two guide rollers 3 are installed in parallel on the upper inner side of the washing chamber, and two wrapping rollers 4 are installed in parallel on the lower inner side of the washing chamber. Two hollow plates 5 are rotatably installed on the side wall of the cleaning chamber. A cleaning roller 6 is movably installed at the bottom side of the hollow plate 5. The other end of the cleaning roller 6 is rotatably connected to a positioning plate 7, which is rotatably installed on the other side wall of the cleaning chamber. Two arc-shaped telescopic rods 8 are symmetrically installed on the side wall of the cleaning chamber. The movable ends of the two arc-shaped telescopic rods 8 are fixedly connected to the side of the hollow plate 5. A compression spring 9 is provided inside the arc-shaped telescopic rod 8, and the arc-shaped telescopic rod 8 can compress the compression spring 9 when it extends or retracts. A motor 10 is installed at the top of the outer side of the hollow plate 5. One end of the output shaft of the motor 10 movably passes through to the upper inner side of the hollow plate 5 and is fixedly connected to a pulley 11. One end of the cleaning roller 6 movably passes through to the lower inner side of the hollow plate 5 via a shaft and is also fixedly connected to a pulley 11. The two pulleys 11 are connected by a transmission belt. The above-mentioned technical solution, during the fabric washing and conveying process, involves the fabric being wound around the guide roller 3 on one side, then exiting from below the two wrapping rollers 4, and finally exiting from above the guide roller 3 on the other side. The distance between the two guide rollers 3 is relatively large, while the distance between the two wrapping rollers 4 is relatively small, forming an overall inverted trapezoidal structure. During fabric conveying, the two washing rollers 6 respectively adhere to the fabric at the two inclined surfaces of the trapezoidal structure. The washing rollers 6 are driven to rotate by the motor 10 in conjunction with the pulley 11 and the transmission belt. With a soft-bristled structure, the cleaning chamber is filled with cleaning fluid, which covers the cleaning roller 6. This allows the cleaning roller 6 to brush the fabric surface during rotation. The arc-shaped telescopic rod 8 has a built-in compression spring 9. Initially, the compression spring 9 pushes the telescopic end of the arc-shaped telescopic rod 8 to its maximum range, causing the telescopic end of the arc-shaped telescopic rod 8 to drive the cleaning roller 6 on the hollow plate 5 to press against the fabric surface, ensuring full contact with the fabric. The compression spring 9 provides flexible compensation space, preventing the fabric from breaking due to excessive tension caused by the rotation of the cleaning roller 6.

[0020] A stirring rod 12 is installed in the middle of the inner side of each of the two cleaning chambers. Stirring blades are evenly distributed on the outer side of the stirring rod 12. A motor 2 13 is installed on the outer wall of the frame 1. One end of the output shaft of the motor 2 13 is connected to the shaft end of one of the stirring rods 12. The other ends of the two stirring rods 12 move through the side wall of the frame 1 and are fixedly connected to a pulley 2 14. The two pulleys 2 14 are connected by a transmission belt. In the above-mentioned technical solution, the stirring rod 12 is set in the inverted trapezoidal structure space formed by the guide roller 3 and the wrapping roller 4. By rotating the stirring rod 12, the stirring blade can stir the cleaning liquid, causing the water in the cleaning chamber to fluctuate and impact the surface of the fabric, thereby improving the cleaning effect of the fabric. Additionally, it should be noted that the two cleaning chambers can be filled with liquids of different temperatures, and can be used in conjunction with existing temperature control devices to achieve the desired cleaning environment for the fabric.

[0021] Both the hollow plate 5 and the positioning plate 7 are fixedly connected to the outer side of the movable column 15. Arc-shaped holes are opened on both sides of the frame 1 at the positions corresponding to the movable column 15, and the movable column 15 is slidably set inside the arc-shaped hole. The above-mentioned technical solution, through the setting of movable column 15 and arc-shaped hole, can limit the range of motion of hollow plate 5 and improve its stability. Its range of motion is small, and during movement, the arc-shaped telescopic rod 8 can squeeze and compress spring 9 through its telescopic end.

[0022] A baffle 16 is installed on the inner side of the rear end of the frame 1, and a spray chamber is formed between the baffle 16 and the adjacent partition 2. Two guide rollers 17 are installed in parallel above the inner side of the spray chamber, and two cloth-winding rollers 18 are installed in parallel below the inner side of the spray chamber. Perforated plates 19 are installed on both sides below the two cloth-winding rollers 18. An extrusion plate 26 is provided above the perforated plate 19. Slide seats 24 are fixedly connected to the top of both ends of the extrusion plate 26. The slide seats 24 are slidably connected to the outside of the slide rail 23, and the slide rail 23 is fixedly connected to the inner wall of the frame 1. A rotating column 25 is fixedly connected to the side of the slide seat 24. The outside of the rotating column 25 is rotatably sleeved on the linkage plate 22. A rotating column 21 is movably sleeved on the top of the linkage plate 22. The end of the rotating column 21 is fixedly connected to the side edge of the rotating disk 20, and the middle of the rotating disk 20 is rotatably installed on the side wall of the frame 1 through a shaft. Motors 28 are installed on both sides of the frame 1. Two sets of spray pipe groups 27 are installed in parallel inside the spray chamber. Multiple spray heads are evenly installed below the spray pipe groups 27. In the above-mentioned technical solution, the two guide rollers 17 and the two wrapping rollers 18 are also arranged in an inverted trapezoidal structure, and the distance between the two wrapping rollers 18 is relatively large to provide space for the extrusion plate 26 to function. The fabric passes over the bottom of the two wrapping rollers 18, and the section of the fabric between the two wrapping rollers 18 is parallel. The perforated plate 19 is located below the fabric to provide support for the fabric, and the perforated plate 19 has a perforated structure to facilitate water discharge and extrusion by the extrusion plate 26. During the fabric conveying process, the motor is started. 28 drives the rotating disk 20 to rotate. The rotation of the rotating disk 20 will drive the slide block 24 to reciprocate linearly along the slide rail 23 through the linkage plate 22, thereby driving the extrusion plate 26 to continuously beat the surface of the fabric, thereby pressing out the sewage inside the fabric. A spray pipe group 27 is set behind each extrusion plate 26. With its function, the fabric can be thoroughly rinsed, thereby providing a fabric cleaning effect. The spray pipe group 27 consists of multiple spray pipes, the ends of which are connected by pipes, and the pipes are connected to the external water supply equipment.

[0023] A pulley 29 is also fitted on the outer side of the central shaft of the rotating disk 20. The two pulleys 29 on the same side are connected by a transmission belt. One end of the output shaft of the motor 28 is connected to the end of one of the shafts of the rotating disk 20. The above-mentioned technical solution, through the action of pulley 29, allows one side motor 28 to simultaneously drive the two rotating disks 20 on the same side to rotate synchronously.

[0024] A feed roller assembly 30 is movably mounted at the front end of the frame 1. Two guide rollers 31 are mounted parallel to each other behind the feed roller assembly 30 on the frame 1. A brush roller assembly 32 is installed between the two guide rollers 31. The brush roller assembly 32 consists of two brush rollers arranged vertically. A motor 4 33 is mounted on the side of the frame 1. One end of the output shaft of the motor 4 33 is connected to the shaft end of one of the brush rollers. The other end of the brush roller shaft passes through the frame 1 and is fixedly connected to a gear 34. The two gears 34 mesh with each other. The above-mentioned technical solution uses a feed roller group 30 consisting of two feed rollers, one above the other. Initially, the fabric passes through the two feed rollers and then wraps around the two guide rollers 31. The fabric is in a parallel section between the two guide rollers 31. Two brush rollers are placed on the upper and lower sides of the fabric, respectively. The rotation of the brush rollers can clean the surface of the fabric and initially remove dust and impurities from its surface.

[0025] Hollow seats 35 are installed on both sides of the inner wall of the frame 1. Multiple air nozzles are evenly installed on one side of the hollow seat 35, and the other side of the hollow seat 35 is connected to an external air supply device through an air pipe 36. The two hollow seats 35 are at different heights and are both located behind the brush roller group 32. In the above-mentioned technical solution, the jet nozzle is connected to the external air supply equipment through the hollow seat 35, thereby spraying high-pressure gas. Of the two hollow seats 35, one is placed above the fabric conveyor and the other is placed below, so that the jet nozzle can blow air onto the fabric surface to further remove dust and impurities from the fabric surface.

[0026] The rear end of the frame 1 is provided with two sets of parallel extrusion rollers 37 and guide rollers 38. The extrusion rollers 37 consists of two extrusion rollers that are flush with each other. The above-mentioned technical solution, through the extrusion roller group 37, can squeeze out the moisture in the fabric when it is conveyed out, which facilitates its subsequent drying.

[0027] Working principle: When the fabric is washed and conveyed, it first passes through the feed roller group 30 at the head, and then wraps around the two guide rollers 31 and the adjacent guide roller 3. Then it wraps around the two wrapping rollers 4 below, and then wraps around the guide roller 3 above, conveying the fabric in an inverted trapezoidal structure. The fabric conveying structure is the same in the two washing chambers. After exiting the washing chamber, the fabric enters the spray chamber, which is also conveyed in an inverted trapezoidal structure. Finally, it wraps around the two extrusion roller groups 37 and the guide roller 38 above in sequence.

[0028] As the fabric passes through the two guide rollers 31, dust and impurities on the fabric surface are pre-removed by the brush roller group 32 and the air nozzle. Then, it passes through the cleaning chambers, each equipped with a water pump to continuously supply water. The water pump is fixed to the side wall of the cleaning chamber by a stainless steel bracket. One end of the bracket is screwed to the middle of the side wall, and the water pump is bolted to the other end. The bracket has a certain length to maintain a distance between the water pump and the cleaning chamber, preventing overflowing waste liquid from damaging the pump. The suspended design of the water pump also prevents waste liquid flowing onto the ground from affecting its operation. A waterproof cover can be installed on the outside of the water pump as needed to reduce the impact of the external environment. The water pump's outlet is connected to an extension tube. The water supply pipe at the bottom of the washing chamber continuously supplies water to the washing chamber as liquid overflows. The water supply pipe extends into the bottom of the washing chamber to better push the wastewater out, maintaining the cleanliness of the liquid in the washing chamber. The washing roller 6 rotates and contacts the fabric surface, while the stirring rod 12 agitates the liquid in the washing chamber, thus thoroughly cleaning the fabric. After washing, the fabric, still soaked in liquid, passes through the spray chamber. The extrusion plate 26 moves up and down to pat the fabric surface, while the spray pipe rinses the fabric, thus removing the wastewater and improving the cleaning effect. Finally, the cleaned fabric passes through the extrusion roller group 37 to remove excess water, facilitating subsequent drying. The frame 1 has corresponding water inlets and drains on both sides.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
