[0002] In swing roller chain sorting machine, swing roller chain relies on the height difference of each level guide rail, realizes the size of swing roller chain roll gap in each classification, thereby completes the sorting work to the material above swing roller chain.
[0003] The previous swing roller roll gap adjusting guide rail mainly has two ways, gradually reduces formula guide rail and ladder reduces formula guide rail respectively. Gradually reduces formula guide rail, when using, can only adjust swing roller roll gap to the maximum value of each level in the end, just can sort out the maximum material of each level in the end, due to the influence of material size and shape and other factors, material will have a great probability to be transported to the next level, like this, the classification effect of swing roller is reduced. Ladder low formula guide rail, guide rail is in the straight state in each level, swing roller roll gap is always in the maximum value in the level range, like this, the sorting precision is improved, but the transition roller way between two levels, transition slope is larger, swing roller is easy to hit the guide rail of next level when the equipment runs fast, causes equipment damage and larger noise.
