Characteristics of the present invention are:
When letter and the pressure that separates belt pulley spare are excessive, separating belt pulley takes differential to separate, namely take the form of intermittent adjusting microinching, repeatedly provide stiction to letter, because stiction is greater than force of sliding friction, therefore letter still can be driven by belt and move forward, until reach the position of setting;
Utilize the suction-operated of inlet valve, the nearest head of distance separation belt pulley seals letter and can be attracted on the separation belt pulley, and itself and adjacent letter are separated, thus easier single the envelope in the passage that enters the separation belt pulley;
Utilize structures such as separating the anterior damping fin 1 that arranges of delivery wheel, damping fin fixed block 2, separate and be provided with corresponding groove 7 on the belt pulley, so that letter with separate belt pulley move forward a bit of after, enter in the slit between damping fin 1 and the groove 7, be the slightly attitude of fold, because the slit between damping fin 1 and the groove 7 is very little, add the autoregulation of damping fin fixed block 2 rear springs, can effectively reduce the above letter of two envelopes and enter probability in the slit, separate failed probability thereby effectively reduce single envelope.
In case two envelope letters have entered in the slit between damping fin 1 and the groove 7 simultaneously, this moment, letter was excessive with the pressure that separates between the belt pulley, servomotor 6 drives the separation belt pulley and carries out adjusting microinching, because the coefficient of friction of damping fin self is larger, damping fin and the second envelope letter produce larger frictional force, and the frictional force of two envelope letter spares is less, so two envelope letters gradually are imbricated and separate under the drive of belt adjusting microinching, after two envelope letters separate fully, the first envelope letter enters the subsequent delivery passage, the second envelope letter progressively moves forward under the drive of belt, finishes single envelope and separates.
Beneficial effect of the present invention is:
1) greatly reduce letter and be forced through tightly, can't drive by separated belt pulley, thus the jammed probability of letter.
2) prevent that effectively the simultaneously separated belt pulley of the above letter of two envelopes or two envelopes from driving, thereby single envelope is separated failed probability.
3) in case two envelope letters, still can continue single envelope separation by the split tunnel of while carry over score from belt pulley, and it is simple to be newly equipped with interposed structure, need not other power set or detection method.
4) efficient and success rate that letter sorting list envelope is separated have greatly been improved.
