[0023] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and do not necessarily describe a specific order or sequence.

[0024] The terms "include" and "have" and any variations thereof in the specification and claims of the present application are intended to cover non-exclusive inclusion, for example, a process, method, system, product or device that includes a series of steps or units does not have to be limited to only those steps or units clearly listed, but can include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0025] As Figures 1-5 shown in the dyeing and drying device of the fleece fabric, comprising a receiving assembly 1 for receiving fuel dripping from the fleece fabric, the specific structure of the receiving assembly 1 comprises a sewer 101, the upper end of the sewer 101 is open, comprising two side walls and a bottom plate, the top of the side wall of the sewer 101 is provided with a hot air circulation assembly 2 capable of generating circulating hot air flow, the hot air circulation assembly 2 has a plurality of hot air circulation assemblies 2, which are arranged equidistantly along the extension direction of the sewer 101, so that the hot air flow received by the fleece fabric is more uniform.

[0026] The hot air circulation assembly 2 comprises a return straight pipe 201 fixedly connected with the top surface of the side wall of the sewer 101, and the upper end of the return straight pipe 201 is fixedly connected with an exhaust elbow 204 through a fan 203. The end of the exhaust elbow 204 away from the fan 203 is downwardly fixedly connected with a flow collecting square pipe 205. In fact, the hot air circulation assembly 2 comprises two return straight pipes 201, and the structures of the two return straight pipes 201 are symmetrical to each other. The upper end of each return straight pipe 201 is connected with the air inlet end of one fan 203, and the air outlet end of each fan 203 is independently connected with one exhaust elbow 204. The ends of the two exhaust elbows 204 are fixedly connected with one flow collecting square pipe 205, and an electric heating rod 206 is arranged in the flow collecting square pipe 205, for heating the airflow, thereby accelerating the evaporation of the solvent on the surface of the velvet fabric.

[0027] The opposite inner wall of the sewer 101 is provided with a stepped groove extending to the top surface, and the bottom surface of the stepped groove is on the same water surface. The sewer 101 is provided with a manhole cover plate 103 in the stepped groove, so the manhole cover plate 103 is also horizontal. Since the longitudinal depth of the stepped groove is less than the thickness of the manhole cover plate 103, the manhole cover plate 103 protrudes from the upper surface of the sewer 101. The two ends of the sewer 101 are fixedly connected with downwardly curved and extended flow discharge bridges 102, for guiding the pigment liquid flowing and collected from the two ends of the sewer 101 downwardly. The manhole cover plate 103 is provided with flow guide grooves 104 penetrating through the upper and lower surfaces. The densely arranged flow guide grooves 104 form a mesh shape, allowing the pigment liquid to flow downwardly, but not allowing the velvet fabric to pass through, so as to prevent the velvet fabric from falling into the sewer 101 which is relatively messy and dirty in color comparison. Since the manhole cover plate 103 has many holes and directly contacts with the hot airflow, the surface of the manhole cover plate 103 is dried relatively quickly. Even if the manhole cover plate 103 contacts with the velvet fabric, the fabric body is not easily contaminated. Therefore, it is necessary to set the manhole cover plate 103. The two return straight pipes 201 of the hot air circulation assembly 2 are provided with backflow openings 202 in the opposite side walls. The hot airflow slightly passing through the velvet fabric enters the return straight pipe 201 through the backflow opening 202. The inner bottom surface of the backflow opening 202 is flush with the upper surface of the manhole cover plate 103, so as to reduce the resistance of the airflow entering the backflow opening 202 and reduce the working noise.

[0028] The printing and dyeing drying device of the still velvet fabric includes a pair of support frames 3, all the hot air circulation assemblies 2 are located between the pair of support frames 3, the upper end of the pair of support frames 3 is constrained by a straight and not easy to deform hard cloth drying rod 4, the cloth drying rod 4 can be placed on the velvet fabric body 5, the cloth drying rod 4 can pass through all the hot air circulation assemblies 2, so that the velvet fabric body 5 is located between the backflow straight pipes 201 and below the flow collecting square pipe 205, and fully contacts with the hot air flow, the specific structure of the support frame 3 includes a vertical column 301, the lower end of the vertical column 301 is fixedly connected with a foot plate 302 which is larger in size and heavier, although the foot plate 302 is relatively difficult to move, but it is usually fixedly connected with the ground to ensure the stability relative to the main part of the drying device, the upper end of the vertical column 301 is fixedly connected with a bracket 303 made of wear-resistant material, the bracket 303 is provided with a sliding groove 304, the sliding groove 304 is a right V-shaped, the bottom of the V-shaped is a circular arc, and is used for cooperating with the cloth drying rod 4 to form a sliding pair, so that the cloth drying rod 4 moves on the bracket 303, and the velvet fabric body 5 enters or leaves the drying area surrounded by the hot air circulation assemblies 2.

[0029] Working principle: in order to facilitate the placement and removal of the velvet fabric body 5, one of the two support frames 3 is very close to one end of the main part of the drying device, and the other is away from the other end of the main part of the drying device, in order to make the velvet fabric body 5 completely leave the hot air area, the distance between the two support frames 3 is at least twice the total length of the arrangement of all the hot air circulation assemblies 2, and the placement width of the velvet fabric body 5 on the cloth drying rod 4 should not be greater than the total length of the side-by-side arrangement of all the hot air circulation assemblies 2, in order to ensure that the cloth drying rod 4 is always in contact with the two brackets 303, the length of the cloth drying rod 4 is at least three times the total length of the arrangement of the hot air circulation assemblies 2; in use, first make the cloth drying rod 4 move away from the support frame 3 away from the main part of the drying device, then place the just printed and dyed velvet fabric body 5 on the cloth drying rod 4 between the support frame 3 and the hot air circulation assembly 2, then push the cloth drying rod 4 in the opposite direction, so that the velvet fabric body 5 enters the space surrounded by the hot air circulation assembly 2, the velvet fabric body 5 is located above the well cover plate 103, the dropped pigment enters the sewer 101 through the flow guide groove 104, the fan 203 is started and the electric heating rod 206 is powered on, the fan 203 draws out the air in the backflow straight pipe 201, negative pressure is generated, the atmosphere outside the fan 203 is pressed into the supplement from the backflow port 202, the pressurized air enters the flow collecting square pipe 205 through the exhaust elbow pipe 204 and is heated by the electric heating rod 206 to become a high-temperature gas flow in contact with the velvet fabric body 5, so as to take away the solvent adsorbed by the velvet fabric body 5 and make it dry quickly, after drying is completed, the fan 203 is closed, the electric heating rod 206 is powered off, and then the cloth drying rod 4 is pulled out, the velvet fabric body 5 is naturally exposed from the main part of the drying device, and finally it can be taken off from the cloth drying rod 4.
