Heat transfer machine for taper objects
For the decoration of cups, it has always been the battleground for special printing processes. Due to the rich colors and expressive power of heat transfer printing, heat transfer printing technology plays an important role in the decoration of cups. For a cylindrical cup, its unfolded surface is a cuboid, which can be done well with an ordinary surface heat transfer machine, but for a cup with a considerable amount of taper, due to its large end and small end After the surface is unfolded, it presents a fan shape, so the transfer of the thermal transfer film will be unbalanced. The large end needs to turn over a longer arc length, and the small end needs to turn over a shorter arc length. In order to accurately transfer the thermal transfer film to the cup in proportion, a heat transfer machine specially used for tapered cups has been developed, which will be installed on the fan-shaped track mechanism according to the thermal transfer film. During the process, the thermal transfer film is rotated at different angles according to the arc lengths of the big end and the small end of the fan, and the pattern of the tapered cup is transferred very accurately.
Theoretically speaking, the cups have a certain taper. If you want to transfer accurately, you must use a taper transfer machine, but if the taper is not too large, you can also use an ordinary thermal transfer machine, but we have to accept the small The graphics and text are deformed.
The heat transfer machine for tapered cups is the same as the ordinary heat transfer machine. It needs to make a jig, and it needs the perfect cooperation of three elements: the heat transfer film and the silicone roller.
