[0026] In order to more clearly understand the technical means of the utility model and implement it according to the contents of the specification, the specific implementation methods of the utility model are further described in detail below in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0027] This specific embodiment relates to a cloth drying device, such as Figure 1 As shown, it includes a drying box 100, and the drying box 100 is used to dry cloth or other fabrics. The drying box 100 is used to dry the fabric by drawing hot dry gas into the box. The temperature of the fabric is controlled by a temperature control system during the drying process. The drying box 100 is usually made of metal materials, such as steel or aluminum. Several transport rollers 200 are arranged at intervals in the drying box 100. The surface of the transport roller 200 can be covered with rubber to prevent the cloth from being scratched by the transport roller 200 during the transportation of the cloth. A drying area for the cloth to pass through is provided between two adjacent transport rollers 200. The drying area is an area in the direction of cloth movement and located between the transport rollers 200. The cloth is dried in the drying area. The gas after drying contains organic solvents, such as alcohols, ketones, ethers, etc., which will affect the health of the staff, so the gas needs to be recovered and processed.

[0028] like Figures 1 to 3 As shown, this specific embodiment also includes a blowing unit 300 arranged above the transport roller 200 and a heating unit used in conjunction with the blowing unit 300, and the heating unit includes a heating wire arranged in the blowing unit 300. The heating unit heats the temperature in the drying machine box 100 to 55°C-105°C. Among them, the drying temperature of cotton fabrics is generally between 55°C and 95°C; the drying temperature of synthetic fiber fabrics, such as polyester and nylon, is generally between 95°C and 105°C. The blowing unit 300 is used for blowing and drying fabrics. A first bracket 310 for mounting the blowing unit 300 is provided on the inner wall of the drying machine box 100, and the first bracket 310 is formed by splicing long strips of metal brackets. The blowing unit 300 blows air from top to bottom, and the fabric is located on the air flow path generated by the blowing unit 300. The blowing unit 300 includes air outlet nozzles 320 evenly spaced on the first bracket 310, and the air outlet of the air outlet nozzles 320 faces the cloth. Hot air flows out through the air outlet nozzles 320. The uniform arrangement can make the gas blown on the cloth more uniform, thereby achieving a better drying effect. The blowing unit 300 also includes an air outlet duct connected to the air outlet nozzles 320, and the other end of the air outlet duct is connected to the positive pressure fan. A heating element, such as a heating wire, is also provided in the positive pressure fan to control the temperature of the wind when the wind is discharged.

[0029] like Figures 1 to 3As shown, this specific embodiment also includes a dehumidification unit 400 arranged in the drying area, and the dehumidification unit 400 is used to recover the airflow blown on the fabric, and the airflow contains printing paste, alcohols in the solvent, ethers and other chemicals. A second bracket 410 for mounting the dehumidification unit 400 is arranged on the inner wall of the drying machine box 100. The second bracket 410 is installed along the length direction of the drying machine box 100. The dehumidification unit 400 includes suction nozzles evenly spaced on the second bracket 410, and the air inlet of the suction nozzle faces the fabric. The gas blown by the air outlet nozzle 320 in the air outlet unit will be blown on the fabric and then recovered by the suction nozzle, thereby forming an airflow for drying the fabric. The second bracket 410 includes a left bracket 411 and a right bracket 412 that are symmetrically arranged, and the suction nozzles on the left bracket 411 and the suction nozzles on the right bracket 412 are staggered, so that the suction nozzles can absorb the airflow in the drying machine box 100 more evenly. The dehumidification unit 400 also includes an air inlet duct connected to the air suction nozzle, and the other end of the air inlet duct is connected to the dehumidifier. The gas flow is driven by the dehumidifier. The dehumidifier includes an air inlet, an evaporator, a compressor, a condenser, a control system, an air outlet duct, a drain pipe and a dryer, so as to dehumidify the drying device. The dehumidifier is used to reduce the humidity inside the drying device, so that the ink on the surface of the cloth is difficult to smudge during the drying process of the cloth, thereby improving the product quality of the cloth. At the same time, the dehumidifier cooperates with the positive pressure fan, and the moisture on the cloth is easier to discharge, so that the drying effect is better. In order to deal with the exhaust gas absorbed by the dehumidification unit 400, an exhaust system connected to the air inlet duct can also be set to discharge the inhaled gas to the external environment or for further treatment.

[0030] like Figure 3 As shown, a filter screen is also provided on the air outlet nozzle 320 and the air inlet nozzle. To filter the gas passing through the air outlet nozzle 320 or the air inlet nozzle. A silencer 321 is wrapped on the outer peripheral wall of the air outlet nozzle 320 and the air inlet nozzle. The air outlet nozzle 320 or the air inlet nozzle is passed through the silencer 321, so that the silencer 321 can reduce the sound when the air outlet nozzle 320 is working. The silencer 321 can be in a circular ring shape and sleeved on the air outlet nozzle 320 or the air inlet nozzle, or it can be in other shapes.

[0031] Embodiment 2: Compared with Embodiment 1, Embodiment 2 is different in that the arrangement of the transport rollers 200 is different. In Embodiment 1, the transport rollers 200 are evenly spaced along the length direction of the drying cabinet 100 .

[0032] like Figures 4 to 6As shown, in the second embodiment, the transport roller 200 includes an upper roller 210 and a lower roller 220 located below the upper roller 210. When the cloth passes through the transport roller, it is first squeezed and then transported by the subsequent transport roller 200. The subsequent transport rollers are staggered up and down, so that the cloth will be wavy during transportation, the drying time of the cloth in the drying box 100 will be extended, the air blowing during drying will be more uniform, and the drying effect of the cloth will be better.

[0033] Working principle: Through the cooperation between the blowing unit 300 whose air outlet is located on the cloth and the dehumidifying unit 400 whose air inlet is located on the cloth, an air flow for drying the cloth is formed above the cloth, so that the cloth can be dried by the air flow after passing through the conveying roller 200, thereby improving the drying efficiency of the cloth. At the same time, the air outlet nozzle 320 in the blowing unit 300 and the air inlet nozzle in the dehumidifying unit 400 are evenly distributed on the drying machine box 100, so that the air flow blowing on the cloth is more uniform.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the technical principle of the present invention, and these improvements and modifications should also be regarded as within the protection scope of the present invention.
