[0015] The present invention has the following advantages: The present invention provides an efficient and energy-saving double-layer water washing device for printing polyester fabrics through improvement. Compared with the same type of equipment, the following improvements are made: In the present invention, by providing a water washing assembly, the nozzles installed on the surfaces of the hollow circular rod I and the hollow circular rod II are arranged to be inclined. When the fabric between the fabric guiding roller II and the winding roller is in a vertical state, the angles between the nozzles and the vertical fabric are the same, ensuring that the heights of the cleaning liquid sprayed by the nozzles on both sides of the fabric during cleaning are the same, so that the same cleaning effect can be obtained on both sides of the fabric, avoiding the situation where one side is cleaned cleanly while the other side is not thoroughly cleaned, and at the same time avoiding damage to the fabric strength. The air pump injects gas into the water tank to increase the pressure, so that the cleaning liquid in the water tank can flow into the hollow circular rod I and the hollow circular rod II through the rigid pipe and the spring pipe and be sprayed from the nozzles to clean the fabric. This pressure-driven method can ensure the full utilization of the cleaning liquid, avoid waste of the cleaning liquid, and at the same time ensure the high efficiency of the cleaning process. The motor drives the winding roller to rotate, so that the fabric on the fabric winding roller is continuously wound onto the winding roller. During the movement of the fabric, the cleaning liquid is automatically sprayed from the nozzles for cleaning, realizing the automation of the water washing process, reducing manual intervention, and improving production efficiency.

[0016] The double - layer water - washing device for printing of an efficient - energy - saving polyester fabric in the present invention is provided with an angle - adjusting component. When the fabric wound on the winding roller increases and the fabric conveying speed continuously increases, the rotating roller, the clamping plate and the sliding rod move synchronously, driving components such as the counterweight ball and the L - shaped rod one to move. Then, through the meshing relationship between gear one and the upper tooth rod, and gear two and the lower tooth rod, the hollow round rod one and the hollow round rod two move in opposite directions simultaneously, realizing the adjustment of the nozzle angle. When the conveying speed is relatively fast, increasing the included angle appropriately can ensure that the cleaning liquid can achieve a good cleaning effect at different fabric conveying speeds during the rapid movement of the fabric.

[0017] The double - layer water - washing device for printing of an efficient - energy - saving polyester fabric in the present invention is provided with a pressure - adjusting component. As the fabric conveying speed increases, the L - shaped rod two moves to drive the connecting shaft to fit and slide on the trapezoidal plate, causing the trapezoidal plate to move downward and compress the spring one, increasing the force exerted on the semi - rubber ball. Since part of the gas in the water tank originally flows out through the gap between the semi - rubber ball and the round tube to maintain the air pressure stability, when the downward force exerted on the semi - rubber ball increases, the gap becomes smaller, the leakage amount of the gas inside the water tank decreases, and the air pressure rises. The speed at which the cleaning liquid flows out along the inside of the nozzle increases. This automatic adjustment mechanism can adjust the flushing pressure in real - time according to the change of the fabric conveying speed, ensuring an appropriate flushing pressure at different conveying speeds, and thus guaranteeing the cleaning effect. The pressure - adjusting component adjusts the gas leakage amount through the gap between the semi - rubber ball and the round tube, maintaining the air pressure inside the water tank within a certain range, avoiding adverse effects on the cleaning process caused by too high or too low air pressure, and ensuring the stability and reliability of the device operation.

The top ends of the side rods 513 are fixedly connected to the carrier plate 510, and the side rods 513 are slidably connected to the cross plate 55.

[0031] Working principle: During use, the rotating shaft of the fabric winding roller 2 is placed inside the inclined groove 31, so that the fabric wound on the surface of the fabric winding roller 2 bypasses the fabric guiding roller 1 32 and the fabric guiding roller 2 33, and one end of the fabric is fixed on the winding roller 34. The fabric guiding roller 2 33 is located below the winding roller 34, and when one end of the fabric is just fixed on the winding roller 34, the fabric between the fabric guiding roller 2 33 and the winding roller 34 is in a vertical state. During cleaning, the spray nozzles 311 respectively installed on the surfaces of the hollow round rod 1 310 and the hollow round rod 2 312 are both inclined. And when the fabric between the fabric guiding roller 2 33 and the winding roller 34 is in a vertical state, the angles between the spray nozzles 311 respectively installed on the surfaces of the hollow round rod 1 310 and the hollow round rod 2 312 and the vertical fabric are the same, thereby ensuring that the heights of the spray nozzles 311 spraying the cleaning liquid on both sides of the fabric are the same during cleaning on both sides of the fabric, and ensuring the cleaning effect on both sides of the fabric; The winding roller 34 can be placed on the support block 36, so that the square rod 38 passes through the inside of the square groove 39 and is inserted into the inside of the hollow shaft 37. When the motor 35 operates, it can drive the winding roller 34 to rotate, and thus the fabric on the surface of the fabric winding roller 2 can be wound on the winding roller 34. When the fabric is wound on the winding roller 34, the air pump 314 operates to inject gas into the inside of the water tank 313, so that the pressure inside the water tank 313 increases. One end of the rigid tube 317 located in the water tank 313 is close to the inner bottom surface of the water tank 313. Therefore, when the air pressure inside the water tank 313 increases, the cleaning liquid inside the water tank 313 can be injected into the inside of the rigid tube 317, and then the cleaning liquid inside the water tank 313 flows into the inside of the hollow round rod 1 310 and the hollow round rod 2 312 along the inside of the rigid tube 317 and the spring tube 316, and thus the two sides of the fabric can be cleaned to avoid damage to the fabric strength; When the fabric wound around the surface of the take-up roller 34 increases, due to the operation of the motor 35, the rotation speed of the hollow shaft 37 always remains unchanged. As a result, the conveying speed of the fabric continuously increases, which in turn drives the synchronous movement of the rotating roller 41, the clamping plate 42, and the sliding rod 43. The sliding rod 43 pulls the counterweight ball 412 upward. The movement of the sliding rod 43 drives the synchronous movement of the first L-shaped rod 45 and the second L-shaped rod 51. The movement of the first L-shaped rod 45 drives the synchronous movement of the connecting rod 410, the lower toothed rod 49, and the upper toothed rod 46, thereby driving the simultaneous reverse movement of the first hollow round rod 310 and the second hollow round rod 312. The upper toothed rod 46 is located above the first gear 47, and the lower toothed rod 49 is located below the second gear 48. Due to the meshing relationship between the first gear 47 and the upper toothed rod 46, and the meshing relationship between the second gear 48 and the lower toothed rod 49, the first hollow round rod 310 and the second hollow round rod 312 are driven to move in opposite directions simultaneously, realizing the adjustment of the angle of the nozzle 311 to adapt to the cleaning requirements at different conveying speeds. When the fabric wound around the surface of the take-up roller 34 increases and the conveying speed of the fabric between the first hollow round rod 310 and the second hollow round rod 312 continuously increases, the second hollow round rod 312 rotates counterclockwise, and the first hollow round rod 310 rotates clockwise. Thus, when the conveying speed is relatively fast, the included angle is appropriately increased, enabling the cleaning liquid to better disperse and cover the surface of the fabric during the rapid movement of the fabric, achieving precise cleaning; The movement of the second L-shaped rod 51 drives the synchronous movement of the coupling shaft 53 through the U-shaped rod 52, causing the coupling shaft 53 to slide along the trapezoidal plate 54. Since the upper surface of the trapezoidal plate 54 is provided with an inclined cutting surface, the movement of the coupling shaft 53 will cause the trapezoidal plate 54 to move downward. The downward movement of the trapezoidal plate 54 squeezes the first spring 56, and thus the force exerted on the semi-rubber ball 57 increases synchronously. Since when gas is injected into the water tank 313 through the air pump 314, the force exerted by the gas inside the water tank 313 on the semi-rubber ball 57 increases, and part of the gas flows out along the gap between the semi-rubber ball 57 and the round tube 59 to maintain the air pressure inside the water tank 313 within a certain range. When the downward force exerted on the semi-rubber ball 57 increases, the gap between the semi-rubber ball 57 and the round tube 59 becomes smaller, and the leakage of the gas inside the water tank 313 decreases, and the internal air pressure increases. At this time, the flow rate of the cleaning liquid flowing out along the inside of the nozzle 311 increases, realizing the automatic adjustment of the flushing pressure with the change of the fabric conveying speed and ensuring the cleaning effect.
