The composite fabric is output by the cloth outlet roller 3 and is conveyed forward on the transfer printing platform 2 through the transfer printing platform 2, the heat transfer film is preheated through the heat conduction belt 9 on the preheating roller 8 after being output by the film outlet roller 5, so that the temperature of the heat transfer film before entering the heat transfer printing roller 7 is relatively increased, and the actual temperature of the heat transfer printing roller 7 only needs to be slightly higher than the required temperature of the heat transfer film under the condition that the heat transfer film needs to reach the required temperature, and the heat transfer film can be quickly heated to the required temperature. Compared with the prior art, the temperature difference between the temperature of the thermal transfer film before entering the thermal transfer roller 7 and the temperature required for transfer printing is small after the thermal transfer film is preheated, so that the heating temperature rise amplitude of the thermal transfer roller 7 in the transfer process of the thermal transfer film is small, the temperature of the thermal transfer roller 7 can be set to be lower than that of the conventional thermal transfer roller 7, the thermal transfer film can reach the required temperature in the transfer process, the temperature of the thermal transfer roller 7 is lower, and the conditions of film shrinkage and the like caused by overlarge heating temperature difference of the thermal transfer film can be avoided, so that the thermal transfer process is stable and reliable. After the thermal transfer printing is finished, when the thermal transfer film is separated from the composite fabric, a blocking roller 10 is used for blocking the thermal transfer film and the composite fabric, and the composite fabric at the thermal transfer printing position can be fluctuated in the separation process of the thermal transfer film and the composite fabric to influence the thermal transfer printing effect.

The preheating roller 8 is internally provided with a heating element, and the thermal transfer roller 7 is also internally provided with a heating element, which are all existing products, and specific structures are not described herein.

The ventilation groove 12 is axially consistent with the baffle roller 10, namely, the length direction of the ventilation groove is perpendicular to the conveying direction of the composite fabric. The air in the ventilation groove 12 is extracted outwards by the exhaust fan 14, and the top of the ventilation groove 12 is covered by the composite fabric, so that negative pressure is formed in the ventilation groove 12, and certain adsorption capacity is generated on the composite fabric, so that the composite fabric is locally adsorbed on the transfer printing platform 2, and the composite fabric is more stable in separation from the heat transfer film. The arrangement of the isolation net 15 on the ventilation groove 12 can prevent the normal and stable forward conveying of the composite fabric from being influenced by the fact that the composite fabric is adsorbed inside the ventilation groove 12.
