[0019] The specific implementation of the present invention is further described below in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0020] The technical solution specifically implemented in the present invention is: like Figures 1 to 5 As shown, a finishing process of a functional fabric includes the steps of using a finishing device to perform a padding and drying treatment on a fabric 100; the finishing device includes a treatment box 1, a padding mechanism and a drying mechanism; The interior of the treatment box 1 is provided with a partition 2, and the partition 2 divides the interior space of the treatment box 1 into a padding chamber 3 and a drying chamber 4 which are connected to each other on the left and right; The padding mechanism is arranged inside the padding chamber 3; The drying mechanism is arranged inside the drying chamber 4, and the drying mechanism includes a drying guide roller 5, a heater 6 and a hot air roller assembly, the hot air roller assembly includes two hot air rollers arranged up and down, the interior of the hot air roller is a hollow structure, and a plurality of air outlet holes 7 are evenly distributed on the circumference of the hot air roller, the air outlet holes 7 are connected to the interior of the hot air roller, one end face of the hot air roller is rotatably connected to the inner wall of the drying chamber 4 through a rotating shaft 8, and the other end face of the hot air roller is provided with a mounting hole, a hot air conveying pipe 9 is fixedly penetrated on the side wall of the drying chamber 4, one end of the hot air conveying pipe 9 is connected to a hot air generating device, the other end of the hot air conveying pipe 9 passes through the mounting hole and extends to the interior of the hot air roller, and the hot air conveying pipe 9 is rotatably connected to the mounting hole of the hot air roller through a sealed bearing 10, the two hot air rollers are respectively an upper hot air roller 11 and a lower hot air roller 12, the upper hot air roller 11 is used to contact with the upper surface of the fabric 100, and the lower hot air roller 12 is used to contact with the lower surface of the fabric 100.

[0021] By adopting the above scheme, the specific process of using the post-finishing equipment to perform padding and drying treatment on the fabric 100 in the method of the present invention is as follows: The fabric 100 in the conveying process enters the processing box 1 and then enters the impregnation chamber 3 and the drying chamber 4 in turn. The impregnation mechanism is used to impregnate the fabric 100 in the impregnation chamber 3, and the drying mechanism is used to dry the fabric 100 in the drying chamber 4. The heater 6 in the drying chamber 4 is used to heat the interior of the drying chamber 4 to increase the temperature inside the drying chamber 4 to a set temperature so as to dry the fabric 100. When the fabric 100 passes between the upper hot air roller 11 and the lower hot air roller 12, the fabric 100 is heated. The upper hot air roller 11 and the lower hot air roller 12 are driven to rotate, and at the same time, the hot air delivery pipe 9 delivers hot air to the inside of the hot air roller, and the hot air roller blows out the hot air through the air outlet holes 7. The hot air blown out of the air outlet holes 7 on the hot air roller that are in contact with the fabric 100 can penetrate into the inside of the fabric 100 to accelerate the drying of the moisture inside the fabric 100. The hot air roller can also iron the fabric 100 during the rotation process, thereby making the fabric 100 smoother after drying, and the fabric 100 that has completed drying is moved out of the processing box 1.

[0022] Furthermore, the drying mechanism also includes an upper air guide cover 13 and a lower air guide cover 14, both of which are tubular. The upper air guide cover 13 is arranged above the upper hot air roller 11, and an upper air guide outlet is arranged at the bottom of the upper air guide cover 13, and the two ends of the upper air guide cover 13 are respectively fixedly connected to the inner wall of the drying chamber 4, and the lower air guide cover 14 is arranged below the lower hot air roller 12, and a lower air guide outlet is arranged at the top of the lower air guide cover 14, and the two ends of the lower air guide cover 14 are respectively fixedly connected to the inner wall of the drying chamber 4. By adopting the above scheme, the upper air guide hood 13 can guide the hot air blown out from the air outlet 7 of the upper hot air roller 11 to the upper surface of the fabric 100, thereby avoiding the loss of hot air and helping to further improve the drying efficiency; similarly, the lower air guide hood 14 can guide the hot air blown out from the air outlet 7 of the lower hot air roller 12 to the lower surface of the fabric 100, so that the upper and lower surfaces of the fabric 100 are heated evenly.

[0023] Furthermore, a dehumidifying fan 15 is provided on the top wall of the drying chamber 4. By adopting the above solution, the dehumidifying fan 15 discharges the water vapor generated during the drying process.

[0024] Furthermore, the padding mechanism includes a finishing liquid 16 and a padding guide roller 17 .

[0025] Furthermore, the finishing liquid 16 includes a fluorine-based water-proof and oil-proof agent. By adopting the above solution, the fabric 100 after the padding treatment has good oil-proof and water-proof properties.

[0026] Furthermore, the finishing equipment also includes an extrusion mechanism, which includes an extrusion box 18 and an extrusion roller assembly. The extrusion box 18 is arranged in the partition 2, and fabric passage openings 19 are respectively provided on both sides of the extrusion box 18, and the bottom plate of the extrusion box 18 is arranged at an angle, and a reflux port 20 connected to the impregnation chamber 3 is provided at the lower end of the bottom plate. The extrusion roller assembly is arranged inside the extrusion box 18, and the extrusion roller assembly includes an upper extrusion roller 21 and a lower extrusion roller 22, and the upper extrusion roller 21 is used to contact the upper surface of the fabric 100, and the lower extrusion roller 22 is used to contact the lower surface of the fabric 100. By adopting the above scheme, the fabric 100 after the padding treatment will enter the squeezing box 18, and the fabric 100 entering the squeezing box 18 will pass between the upper squeezing roller 21 and the lower squeezing roller 22, and drive the upper squeezing roller 21 and the lower squeezing roller 22 to rotate, and the upper squeezing roller 21 and the lower squeezing roller 22 squeeze the fabric 100 to squeeze out the excess finishing liquid in the fabric 100, and the squeezed finishing liquid falls into the padding chamber 3 through the reflux port 20 for reuse.

[0027] Furthermore, a knocking assembly is provided inside the extrusion box 18, and the knocking assembly is arranged on the right side of the upper extrusion roller 21, and the knocking mechanism includes a lifting bar 23, and protrusions are respectively provided at both ends of the lifting bar 23, and the protrusions are slidably connected to the inner wall of the extrusion box 18 through a vertical groove 24, and a spring 25 is connected between the top of the protrusion and the vertical groove 244, and baffles 26 are respectively provided at both ends of the upper extrusion roller 21, and a plurality of shifting blocks 27 are evenly distributed on the circumference of the baffle 26, and the shifting blocks 27 are used to contact one side of the lifting bar 23, and a plurality of knocking rods 28 are connected to the other side of the lifting bar 23, and the plurality of knocking rods 28 are arranged at equal intervals along the length direction of the lifting bar 23, and a knocking head 29 for contacting the upper surface of the fabric 100 is provided at the bottom end of the knocking rod 28. By adopting the above scheme, when the upper squeezing roller 21 rotates, it will drive the baffle 26 to rotate. The baffle 26 can limit the displacement of the fabric 100 during the conveying process, and the baffle 26 will drive multiple shifting blocks 27 to contact the lifting bar 23 in sequence during the rotation process. After the shifting blocks 27 contact the lifting bar 23, they can lift the lifting bar 23 and compress the spring 25. When the shifting blocks 27 are separated from the lifting bar 23, the lifting bar 23 will drive the knocking rod 28 to drop rapidly under the elastic force of the spring 26, so that the knocking rod 28 knocks the fabric 100 through the knocking head 29, thereby knocking down the finishing liquid droplets attached to the surface of the fabric 100 to avoid affecting the subsequent drying efficiency. The knocked finishing liquid droplets fall into the immersion chamber 3 through the reflux port 20 for reuse.

[0028] Furthermore, a fabric inlet 30 is provided on the side wall of the padding chamber 3 , and a fabric outlet 31 is provided on the side wall of the drying chamber 4 .

[0029] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
