The invention discloses a flocking fabric thermo printing device which comprises a base, a support column and a pump seat, wherein a working table is arranged on the base, a gravity sensor is arrangedin the working table, locating blocks are arranged on the two sides of the working table, a control main engine is arranged on the side surface of the base, a display screen is arranged on the surface of the control main engine, and a control keyboard is arranged by the side of the display screen. The flocking fabric thermo printing device has the advantages that by the aid of a feedback controlloop formed by a temperature sensor, the control main engine and a heating plate, automatic temperature control heating can be realized, constant-temperature thermo printing can be performed to the fabric, the thermo printing processing quality is guaranteed, at the same time, by the aid of a feedback control loop formed by the gravity sensor, the control main engine and an air pump, the intensityduring thermo printing can be controlled to the preset value in real time, the situation that the fabric is damaged due to too large intensity or the processing efficiency is affected by too small intensity is prevented, the thermo printing processing quality is further guaranteed, and the use is convenient.
