An automatic embossing device for plastic floor tile comprises a main frame, a pressing wheel module, a tape supply control wheel module, a position mark sensing module, a tape tension-balancing module, and a tape supply module. When the pressing process for plastic floor tile is performed, the rotation speed of the pressing wheel is first set. The rotation speed of the tape supply control wheel is then set. A zero-point position of rotation angle on the pressing wheel is randomly set. A computer is used to partition and determine a plurality of angle positions; The computer is used to compare the signal of the angle position to that of the position mark on the printed tape to obtain a time difference when the pressing process starts. A distance difference is obtained from the time difference. The computer is used to calculate out the speed compensation according to the rotation speed of the tape supply, control wheel and to adjust immediately the rotation speed of the tape supply control wheel. The angle position and the position mark on the printed tape can thus be kept synchronous at any time. The shift between the pattern on the pressing wheel and the printed pattern on the tape is input to the computer. The computer uses the shift to adjust automatically the zero-point position of rotation angle on the pressing wheel. The pattern on the pressing wheel overlaps the printed pattern on the tape. Normal position adjustment process is then performed. The rotation is thus automatic and continuous.
