Feature of the present invention is:
When the pressure of letter and separated belt pulley part is excessive, separated belt pulley takes differential separated, take the form of intermittent adjusting microinching, repeatedly to letter, provide stiction, because stiction is greater than force of sliding friction, therefore letter still can be driven and move forward by belt, until reach the position of setting;
Utilize the suction-operated of inlet valve, the nearest head of the separated belt pulley of distance seals letter and can be attracted on separated belt pulley, itself and adjacent letter are separated, thereby more easily single envelope enters in the passage of separated belt pulley;
Utilize the structures such as the anterior damping fin 1 arranging of separated delivery wheel, damping fin fixed block 2, on separated belt pulley, be provided with corresponding groove 7, make letter with separated belt pulley move forward a bit of after, enter in the gap between damping fin 1 and groove 7, be the attitude of fold slightly, because the gap between damping fin 1 and 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 the probability in gap, thereby effectively reduce the separated failed probability of single envelope.
Once two envelope letters have entered in the gap between damping fin 1 and groove 7 simultaneously, now letter is excessive with the pressure between separated belt pulley, servomotor 6 drives separated belt pulley to carry 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 parts is less, so two envelope letters are gradually imbricated and separate under the drive of belt adjusting microinching, after the complete separation of two envelope letters, the first envelope letter enters subsequent delivery passage, the second envelope letter progressively moves forward under the drive of belt, complete single envelope separated.
Beneficial effect of the present invention is:
1) greatly reduce letter and be forced through tightly, cannot drive by separated belt pulley, thus the jammed probability of letter.
2) effectively prevent that the simultaneously separated belt pulley of the above letter of two envelopes or two envelopes from driving, thus the separated failed probability of single envelope.
3) once two envelope letters by while carry over score the split tunnel from belt pulley, still can continue single envelope separated, and it is simple to be newly equipped with interposed structure, without other power set or detection method.
4) greatly improve letter sorting list and sealed separated efficiency and success rate.
