Rubber mixing process based on liquid natural rubber

According to the rubber mixing process based on the liquid natural rubber, a mixing tank is included, a feeding tank is embedded in the middle of the top end of the mixing tank, a hoisting seat located in the mixing tank is arranged below the feeding tank, a transmission shaft is movably installed at the bottom end of the hoisting seat, and the outer side face of the transmission shaft is fixedly sleeved with a heating pipe. According to the automatic quantitative material injection device, rotary power is converted into vertical reciprocating motion again after being converted into the rotary power, automatic material injection and automatic material injection stopping are achieved through the vertical reciprocating motion, and the automatic quantitative material injection process in unit time is achieved through a touch switch due to cooperation of an electromagnetic valve and vertical reciprocating motion of a piston plate; quantitative feeding of the rubber additive in unit time is realized, the problems
