PURPOSE: A speed regulator of a laminator is provided to prevent defective lamination due to an shortage of driving force attendant upon low voltage applied to a drive motor when laminating a thick material at low speed, by controlling a speed ratio conversion which is convertible according to speed acceleration or deceleration on a driving force transmission path from the drive motor to a drive roller. CONSTITUTION: A speed regulator of a laminator comprises a housing(10) installed at a body of the laminator; a input shaft(14) installed in the housing and supplied with power from a drive motor(12); a multi-stage gear(16) of driving side including a reduction gear(16a) and a multiplying gear(16b) which are rotated together being installed at the input shaft; a multi-stage gear(20) of driven side including a reduction gear(20a) and a multiplying gear(20b) which are respectively engaged to the reduction gear and the multiplying gear of driving side; a hollow output shaft(18) installing the multi-stage gear of driven side at the housing to be capable of idling; and a shift gear(26) movably installed in the axial direction of the output shaft to regulate a power transmission route between the multi-stage gear of driving side and the multi-stage gear of driven side. |
