[0002] Generally, fiber fabrics are usually contaminated by dust and chemicals after production. Dyed fiber fabrics need to be pre-washed after washing to prevent dehydration, while fiber fabrics used for clothing purposes need to be pre-washed to prevent deformation of the fabrics caused by heat. When a large amount of fiber fabrics that are washed and contain moisture need to be dried quickly at the same time, a dryer is usually used because natural drying is restricted by time and place. Existing fiber fabric dryers include: a supply roller for transferring washed fiber fabrics, a drying unit for drying fiber fabrics, a transfer roller for transferring fiber fabrics that have passed through the drying unit to a side cavity, and these units are connected to form a fiber fabric drying device.
[0003] The hot air dryer in the prior art can usually only dry one side of the fabric, that is, it cannot dry the upper and lower surfaces of the fabric at the same time, and the drying efficiency will be greatly reduced due to the uneven distribution of hot air flow in the drying oven. In view of the above problems, a solution is proposed below. Utility Model Content

A motor 18 is installed on one side of the oven 1. The output shaft of the motor 18 is fixedly connected to one end of the gear a16. The gear a16 can be driven to rotate by the rotation of the motor 18. Since the gear b17 is respectively meshed with the two gears a16, the two gears a16 can be rotated simultaneously through the gear b17, and the rotation directions are opposite. Finally, the two drying rollers 2 can be rotated simultaneously to facilitate the transmission of the fabric, and the upper and lower surfaces of the fabric can be laminated and dried at the same time.

[0022] A cavity 3 is provided in each drying roller 2, and a plurality of air vents 4 are respectively provided on the surfaces of the two drying rollers 2, and the plurality of air vents 4 are respectively communicated with the cavity 3. An air supply disk 5 is provided at one end of each drying roller 2, and the air supply disk 5 is rotatably connected to the drying roller 2.
