Limiting grooves 112 are provided on the inner walls on both sides of the through grooves 111. The outer walls of the limiting protrusions 221 and the limiting grooves 112 are slidably connected. The connecting plate 22 extends through the through grooves 111 to the outside of the dehydration box 1. Telescopic springs are provided on the outer side of the connecting plate 22. The telescopic spring rod 25 provides movement space for the running nonwoven fabric, preventing blockage and hindering its movement. Adjusting plates 26 are fixedly connected to the upper ends of the left and right telescopic spring rods 25. Mounting plates 28 are fixedly connected to the upper surface of the dehydration tank 1, located at the front and rear sides of the vacuum suction chamber 11. An adjusting rod 27 is threaded into one mounting plate 28, and a guide rod 29 is slidably connected into the other mounting plate 28. This adjustable structure allows for adjustment of the distance between the adsorption cylinder 21 and the arc-shaped plate 24, preventing excessive compression and damage. The fiber structure allows for easy adjustment by the user from the outside of the dehydration tank 1. Adjustment rod 27 and guide rod 29 are respectively located at the front and rear ends of the adjustment plate 26. A support plate 23 is fixedly connected between the front and rear connecting plates 22, and an arc-shaped plate 24 is fixedly connected between the left and right support plates 23. Rollers 241 are rotatably connected to the grooves arranged in the arc-shaped plate 24. An adsorption cylinder 21 is rotatably connected inside the vacuum suction chamber 11 and above the arc-shaped plate 24. Adsorption holes 211 are arranged on the outer surface of the adsorption cylinder 21. The front end of the 21 has an adsorption port 212. A connecting pipe 213 is provided in the adsorption port 212 through a bearing. The connecting pipe 213 extends through the dehydration box 1 to the outside of the dehydration box 1. A vacuum pump 214 is installed at the water outlet end of the connecting pipe 213. A water storage tank 215 is installed at the water outlet end of the vacuum pump 214. By sequentially setting a vacuum water absorption chamber 11, a pneumatic dehydration chamber 12 and an infrared drying chamber 13 in the dehydration box 1, efficient dehydration is achieved while protecting the fiber structure. The vacuum water absorption chamber 11 adopts a negative pressure dehydration method, which can efficiently remove free water.

[0030] like Figure 2 As shown, an airflow jet pipe 121 is fixedly connected inside the air pressure dehydration chamber 12. The airflow jet pipe 121 has nozzles 122 arranged at a 45° angle. The nozzles 122 form an acute angle with the running direction of the nonwoven fabric. A high-pressure centrifugal fan 123 is installed at the air inlet end of the airflow jet pipe 121.

The movement of the nonwoven fabric causes the adsorption cylinder 21 to rotate, and at the same time, the vacuum pump 214 is activated to generate negative pressure, so that the air pressure in the adsorption cylinder 21 is lower than the external atmospheric pressure, thereby forming a negative pressure environment. When the nonwoven fabric is squeezed, the water in it is drawn into the adsorption cylinder 21 through the adsorption holes 211, and enters the water storage tank 215 through the connecting pipe 213, thus achieving dewatering; the pneumatic dewatering chamber 12 is provided with obliquely arranged nozzles 122, so that the airflow generates an outward component force along the fabric surface while penetrating the nonwoven fabric, promoting the peeling of surface moisture; carbon fiber quartz tubes are arranged in the infrared drying chamber 13, which are linked with the pre-dewatering unit for further dewatering;

[0033] When the nonwoven fabric is squeezed, in order to avoid excessive compression and damage to the fiber structure, the user can rotate the adjusting rod 27 to move the adjusting plate 26 up and down, thereby moving the connecting plate 22 up and down, so as to adjust the distance between the adsorption cylinder 21 and the arc plate 24.
