A control method of feeding weight of plastic particles based on speed regulating motor and weight feedback is characterized in that it includes a central processor (71), which is electrically connected to a motor controller (72), and the motor controller (72) drives a actuator (73) to drive a controlled object (74) to complete an operation, so that a mixing bin (4) outputs the corresponding amount of materials, and characterized in that a detection device (75) is set on the controlled object (74), and the detection device (75) is communicated with the central processor (71).

A machine learning method includes: acquiring a state variable including at least one first evaluation parameter related to performance evaluation of a kneaded product and at least one kneading condition; calculating a reward for a decision result of the at least one kneading condition based on the state variable; updating a function for deciding the at least one kneading condition from the state variable based on the reward; and by repeating the update of the function, deciding a kneading condition under which the reward obtained becomes maximum, in which the at least one first evaluation parameter includes at least one of physical properties and shape characteristics related to the kneaded product.

Glycerin and sodium polyacrylate may be mixed at a first mixing speed for a first mixing time. Free water and a fibrillated cellulose mixture may be added to second mixer and mixed at a second mixing time speed for a second mixing time. The glycerin and the sodium polyacrylate may be mixed with the free water and fibrillated cellulose mixture at a third mixing speed for a third mixing time. One or more of sodium citrate, sodium bicarbonate, and sodium benzoate may be added and mixed at a fourth mixing speed for a fourth mixing time. Sodium carbonate may be added and mixed at a fifth mixing speed for a fifth mixing time. A surfactant mixture and optionally fragrances may be added and mixed at a sixth mixing speed for a sixth mixing time to form a final mixture, which may be transferred to molds, dehydrated, and removed.

A rubber composition manufacturing method comprising an operation in which an intermeshing internal kneader is used to knead at least rubber, silica, and silane coupling agent, wherein the operation comprises a first step in which kneading which is accompanied by increase in kneading temperature is carried out during an initial phase of the operation; kneading is carried out during the first step while a ram is maintained in a state in which it is at a first position which is higher than a lowermost position within a range of movement of which the ram is capable; and during the first step, an effective volume when the ram is at the first position is 105% to 120% relative to a value of 100% for an effective volume when the ram is at the lowermost position.
