Opening machine mixing process is divided into three stages: wrapping rollers, eating powder and refining.
The operation process is good as follows: the raw rubber or plastic rubber, mother rubber, etc. along the side of the big tooth wheel into the two rollers in the seam of the opener, the roller distance control in 3-4 mm, rolling 3 a 4 minutes. clock, so that it wrapped in the front roller, the formation of smooth and gapless roller rubber, at this time all the rubber will be removed, the roller distance to 10 - 11 mm, and then put the rubber into the za smelting for 1 minute. About. According to the number of wrapped roll rubber cut down part of the remaining rubber, so that the end of the wrapped roll rubber to maintain a certain amount of accumulation of rubber.

Then according to the order of the material to add with the agent, will be with the agent rolled into the rubber in this process for the process of eating powder, plus filler should pay attention to let the powder naturally into the rubber and the Rubber fully mixed, do not take the cutter too early, while gradually widen the roller distance, in order to maintain the number of stacked rubber in the appropriate range, to be all the powder to listen to eat up After the powder is all listened to and eaten, cast the remaining rubber under the cut, by the central cutter to the two ends, and then slowly add liquid softener, continue to roll for 4-5 minutes, to be all mixed well, cut the next Volume, to reduce the stacking section, the purpose of refining is to make the rubber material into a further mixing of uniform uniform, refining method has a slanting knife method, (eight knife method) to play the bundle operation method, to play the triangular Bundle method and pounding glue method (super method) and so on several kinds, more effective is the eight knife method, that is, along the roller axial parallel direction at an angle of 45 ° angle to roll cut, left and right kinds of four times, turnover Refining 3-4 minutes, refining is completed, and then a time to adjust the roller distance to 4-5 mm, with the cut down method to supplement refining 2-3 times, the next piece of parking. The roller temperature is controlled at 45°C About. The whole mixing process is completed.
