The temperature monitoring system includes a temperature sensor, a temperature controller, and a temperature display screen 615 for displaying a temperature value. The pressure monitoring system includes a pressure sensor built into the lift cylinder 601, a pressure controller, and a pressure display screen 616 for displaying pressure values. The lifting driving mechanism is arranged on the L-shaped support, the upper part of the L-shaped support 617 is provided with a coaming 614 surrounding the lifting driving mechanism, and the temperature display screen 615 and the pressure display screen 616 are arranged on the front surface of the coaming 614, so that an operator can visually check the working temperature and pressure of the scalding head 609 conveniently. The bottom surface of first metal block is equipped with the long-temperature cloth 618 of teflon, the relative both sides of the long-temperature cloth 618 of teflon turn over to the top of first metal block upwards, connect through spring 619 between the relative both sides of the long-temperature cloth 618 of teflon, make the long-temperature cloth 618 of teflon can wrap up first metal block tightly, the hot pressure face of the hot head 609 that scalds of convenient clearance of setting up of the long-temperature cloth 618 of teflon. The temperature and pressure of the hot stamping head 609 can be monitored, and when equipment is debugged, the equipment can be debugged quickly according to the temperature and pressure which are displayed visually; the operator can reduce the working state of the thermal transfer printing head in real time, so that the hot head 609 is at the optimal working temperature and pressure, and the thermal transfer printing effect is improved.
