Heat transfer printing equipment with high printing quality

The invention relates to heat transfer printing equipment with high printing quality. The heat transfer printing equipment comprises a stand, a frame, a charging barrel fixing mold core, and a heat transfer printing frame connected with the frame through a lead screw, wherein the heat transfer printing frame comprises a heat transfer printing frame body, a heat transfer printing film guide frame and a heat transfer printing roller; a heat transfer printing film inlet roller and a waste film collecting roller are respectively mounted at the two ends of the heat transfer printing film guide frame; and a manual adjusting device and a laser calibrator are arranged on each of the heat transfer printing film inlet roller and the waste film collecting roller. The distance between the heat transfer printing roller and the charging barrel fixing mold core is changed and adjusted through the lead screw, so that the pressure therebetween can be adjusted to an optimal value; a printed pattern is guaranteed to be parallel to a charging barrel through the laser calibrators so as to improve the printing quality; a photoelectric sensor is arranged on the heat transfer printing film guide frame, and the control end of the photoelectric sensor is connected with the cylinder for detecting a heat transfer printing film control point; the cylinder automatically drives the heat transfer printing roller to vertically move to finish the printing, so that the efficiency is improved; and a temperature sensor is arranged in the heat transfer printing roller, and the control end of the temperature sensor is connected with heating equipment of the heat transfer printing roller for controlling the temperature of the heat transfer printing roller so as to guarantee the printing quality.
