The invention relates to plastic product production equipment with toxic gas eliminating and drying functions. The plastic product production equipment comprises a main body, wherein a drying box, a driving mechanism, a drying mechanism, a treating mechanism, a melting box and a production box are arranged in the main body, wherein the driving mechanism comprises a motor, a first gear, a transmission shaft, a second gear, a third gear and a rotary shaft; the drying mechanism comprises a fourth gear, a cross beam, a communicating pipe and two mixing units; and the treating mechanism comprises aheating unit, an extraction unit, an air supplying unit and a combustion unit. The plastic product production equipment with toxic gas eliminating and drying functions can dry raw materials through the drying mechanism to prevent surface coarseness of a product as a result of water in the raw materials or air bubbles in a plastic melt. Therefore, the plastic product production equipment can extract harmful gas generated by melting a plastic through the treating mechanism and heat the melting box by combusting the harmful gas, so that the energy sources are saved.
