[0002] Thermal transfer film is a special functional printing film with a multi-layer structure, which is used to transfer patterns to the surface of an object through heat pressing. Thermal transfer film plays an important role in the modern decoration and printing industry. As an innovative surface decoration material, thermal transfer film is being adopted by more and more industries with its unique advantages. With the continuous advancement of technology and the continuous expansion of market demand, thermal transfer film will show its unique charm in more fields in the future, providing more possibilities for product decoration. The adjustment of thermal transfer film requires the use of thermal transfer film support guide components.

The object 13 to be printed is placed between the two automatic rollers 3, and the thermal transfer film body 14 is in contact with the surface of the object 13 to be printed. The electric telescopic rod 15 extends and moves with the moving block 4, so that the support rod 5 moves downward with the printing film roller 6 to be in contact with the object 13 to be printed. At this time, the fixed frame 7 moves with the support rod 5, so that the surface of the rotating shaft 12 presses the thermal transfer film body 14.
