[0012] A nylon-polyester fabric dyeing and finishing method comprises the following steps: S1. Prepare the dyes needed for dyeing and finishing of nylon and polyester fabrics, and check the functions of the equipment. Then place the nylon and polyester fabric placement rollers between the side panels and fix them. S2. After the nylon / polyester fabric placing roller is fixed, the nylon / polyester fabric passes under the pressing roller, passes over the top roller, passes through the squeezing roller and the guide groove, and is finally connected to the traction machine; S3, according to the thickness of the cloth, the driving motor drives the driving gear to rotate, and the driving gear rotates to drive the latch, the moving plate and the moving mounting block to move, so that the moving mounting blocks on the surfaces of the two sets of moving plates move toward the static mounting blocks, so that the squeezing rollers on the sides of the moving mounting blocks and the static mounting blocks approach each other, thereby squeezing the cloth; S4, injecting dye into the dyeing box to complete dyeing and finishing of the nylon-polyester fabric in the dyeing box, the nylon-polyester fabric carrying the dye will be squeezed by the squeezing roller, and the squeezed dye falls onto the surface of the unloading plate, and the surface of the unloading plate is provided with a plurality of unloading holes, and the dye enters the storage bin through the unloading holes, is poured into the unloading port through the guide plate, and returns to the inside of the dyeing box through the unloading port; S5. Real-time observation of the tension of nylon-polyester fabrics. When the nylon-polyester fabrics overlap and the tension is insufficient, the servo motor is used to drive the gear on the surface of the rotating rod to rotate. The rotation of the gear drives another rotating rod to rotate through the chain, so that the two sets of rotating rods rotate synchronously. Since the rotating rod is fixedly connected to the threaded rod, the two threaded rods will drive the pressure roller or the top roller to move during the synchronous rotation, thereby changing the tension of the fabric; S6.

After adapting to the thickness of the fabric, the fabric passes through the guide groove and is connected to the traction machine, so that the traction machine pulls the fabric. During the dyeing and finishing of the fabric, if the tension of the fabric needs to be adjusted, the gear on the surface of the rotating rod can be driven to rotate by the set servo motor. The rotation of the gear will drive another rotating rod to rotate through the chain, so that the two sets of rotating rods rotate synchronously. Since the rotating rod is fixedly connected to the threaded rod, the two threaded rods will drive the pressure roller or the top roller to move during the synchronous rotation, thereby changing the tension of the fabric, improving the practicality of the device, and avoiding the uneven dyeing and finishing caused by the stacking of fabrics; 2. During the dyeing and finishing process of the cloth, the cloth will be squeezed by the squeezing roller, and the squeezed dye will fall onto the surface of the unloading plate. The surface of the unloading plate is provided with several unloading holes.

5. The dyeing and finishing equipment for nylon and polyester fabrics according to claim 1, characterized in that: The recycling component comprises a material storage bin (513), the material storage bin (513) being located at the bottom of the extrusion bin (501), a material discharge plate (510) being arranged on the top of the material storage bin (513), the material discharge plate (510) being provided with a plurality of material discharge holes (511), a material guide plate (512) being arranged inside the material storage bin (513), the material guide plate (512) being arranged in an inclined manner, a material discharge port (514) being arranged on a side of the material storage bin (513) close to the impregnation and dyeing box (101), the material discharge port (514) being connected to the material storage bin (513) and the impregnation and dyeing box (101), and a material return plate (515) being arranged on a side of the material discharge port (514) close to the impregnation and dyeing box (101).

6. A method for dyeing and finishing nylon / polyester fabrics, applied to a nylon / polyester fabric dyeing and finishing device according to claims 1 to 5, characterized in that: Includes the following steps: S1, preparing the dyes required for dyeing and finishing of nylon and polyester fabrics, and checking the functions of the equipment, and then placing the nylon and polyester fabric placement roller (4) between the side plates (3) and fixing them; S2, after the nylon / polyester fabric placement roller (4) is fixed, the nylon / polyester fabric passes from under the pressing roller (105), passes from above the top roller (106), then passes through the squeezing roller (503) and the guide groove (516), and finally is connected to the traction machine (6); S3, according to the thickness of the cloth, the driving motor (504) drives the driving gear (509) to rotate, and the driving gear (509) drives the latching teeth (508), the movable plate (506) and the movable mounting block (507) to move, so that the movable mounting blocks (507) on the surfaces of the two sets of movable plates (506) move toward the static mounting blocks (519), so that the squeezing rollers (503) on the sides of the movable mounting blocks (507) and the static mounting blocks (519) are brought closer to each other, thereby squeezing the cloth; S4, injecting dye into the dyeing box (101) to complete dyeing and finishing of the nylon / polyester fabric in the dyeing box (101); the nylon / polyester fabric carrying the dye is squeezed by the squeezing roller (503); the squeezed dye falls onto the surface of the unloading plate (510); a plurality of unloading holes (511) are provided on the surface of the unloading plate (510); the dye enters the interior of the storage bin (513) through the unloading holes (511); is poured into the unloading port (514) through the guide plate (512), and returns to the interior of the dyeing box (101) through the unloading port (514); S5, real-time observation of the tension of the nylon-polyester fabric. When the nylon-polyester fabric overlaps and the tension is insufficient, the servo motor (109) is used to drive the gear on the surface of the rotating rod (108) to rotate. The rotation of the gear drives another rotating rod (108) to rotate through the chain (107), so that the two sets of rotating rods (108) rotate synchronously. Since the rotating rod (108) is fixedly connected to the threaded rod (103), the two threaded rods (103) will drive the pressure roller (105) or the top roller (106) to move during the synchronous rotation, thereby changing the tension of the fabric; S6. After dyeing and finishing, the entire device is cleaned.
