[0002] Thermal transfer printing first uses printing to print special printing dyes onto transfer paper, and then transfers the dyes onto fabrics through heating and pressurization. Specifically, it is based on the sublimation characteristics of disperse dyes, selects disperse dyes with a sublimation temperature range of 180-240°C, mixes them with slurry to make color ink, and prints the color ink onto transfer paper according to different patterns and design requirements. The transfer paper with patterns and designs is brought into close contact with the fabric, and processed on a transfer printing machine at 200-230°C for 10-30s. The dye is transferred from the printing paper to the fabric and diffuses into the fabric to achieve the purpose of coloring.

[0003] During the pre-treatment process of thermal transfer printing, it is necessary to convey the fabric. In the prior art, the fabric roll is generally sleeved on the conveying device, so that the outer end of the fabric is connected to the winding device, and the winding device is wound to drive the fabric roll on the conveying device to rotate so that the fabric is separated from the fabric roll. The fabric can be pre-treated during this conveying process, so as to realize the conveying of the fabric roll. During this conveying process, the fabric can be pre-treated, but when a roll of fabric is processed, it is necessary to remove the current roll and replace it with a new roll. The existing conveying device is troublesome and laborious to disassemble the roll. Generally, it is disassembled and installed by rotating the bolts multiple times, thereby reducing the efficiency of fabric printing and the practicability of the conveying device.
