[0041] Working principle: when the printing object is put into the device, the printing object will contact the first roller 5, and since the first roller 5 is in close contact with the second roller 7, the printing object will generate different degrees of pressure on the first roller 5 after contacting the first roller 5, which will drive the sliding block 3 to move upward to give the spring 4 pressure. When the spring 4 is subjected to pressure, it will deform, and at this time, the pressure received by the spring 4 will be transmitted to the pressure sensor 6 at the other end, so as to assist the pressure sensor 6 and the control panel 24 to adjust the height of the sliding seat 19, realize automatic and accurate pressure adjustment, and solve the problems of blurred pattern and uneven color in the transfer process;
[0042] In this process, the pressure sensor 6 converts the pressure transmitted by the spring 4 into an electric signal, and the CUP inside the control panel 24 converts the data for calculation.

In this way, heat can be efficiently transmitted from the hot plate to the surface of the printing object, and uniform heat transmission to the transfer area is ensured. In this process, the heat shield 13 plays a role in reducing heat loss, so that heat can be more concentrated for the transfer process, and the problem that ink cannot be fully and accurately transferred to the surface of the printing object in the transfer process is solved.
