The conveying speed of the mechanism is consistent. 9. The intelligent material plasticizing single-line production system according to claim 1, wherein the cutting mechanism includes a support frame and a meter counter and a cutting knife installed on the support frame, and the support frame is provided with A transmission hole that matches the shape of the plastic product, the cutting knife is set in the transmission hole, the meter counter detects the length of the plastic product passing through the transmission hole in real time and controls when the plastic product passes through the preset length The cutting knife performs cutting, and the controller is connected with the meter counter to control the work of the meter counter and adjust the value of the preset length in the meter counter. 10. The intelligent material plasticizing single-line production system according to claim 1, wherein the control temperature corresponding to the cooling mechanism has at least two levels, and the controller controls the temperature of the plastic product after the cooling mechanism is cooled. When the temperature exceeds the corresponding level of control temperature, the corresponding number of sprinkler heads is controlled to be turned on, and the number of sprinkler heads corresponding to the low level of control temperature is smaller than the number of sprinkler heads corresponding to the high level of control temperature.
