The safety performance of the mixer has been the major concern of the major enterprises, but the solution is not to cure the root cause, the following is a technical engineer on the operation of the safety operation of the machine:
The operation of open mill personnel need two hands operation on the roller, need to turn glue and tapping, thin, triangle bag and so on, are from morning to night, the mills labor intensity is big, will cause the safety consciousness of the operators will be greatly reduced, this time is the most dangerous.
The more common method in the industry is on the left and right sides of a stop switch, but only very little, imagine, we found that hand are involved, still have time to press the switch? It's too late. That is, in the design of the mixer when it attaches great importance to the safety factor. If a device has a serious security risk, even if the price is very cheap, what happens if the loss outweighs the gain.
Open mill was first adopted by the infrared induction, later found is not feasible, because the rubber temperature has been changed, prone to error. Through continuous research, later used in the knee position, mounted on the circuit and the switch, when feeling dangerous, as long as the knee forward top, open mill immediately execute the two actions, one is immediately stopped, and then immediately reverse. This is the patent of invention. Now perhaps a lot of peers can imitate these features, but the essence is not imitation.
The essence of the drum is not immediately stop, and then is not immediately reversed. Just like driving a car, to immediately stop is difficult, the brakes to a few seconds, this is the crux of the problem.
