A Blowing and Suction System for Letter Separation and Conveying

Abstract

The invention relates to an air blowing and inhaling system for letter separating and conveying. The air blowing and inhaling system is characterized in that an air blowing hole is formed in a letter supplying belt of a letter supplying module for letter separating, an air nozzle is distributed under the air blowing hole and communicated with an air source connection port, and an air blowing opening of the air nozzle is upward. An air supplying system is arranged under or beside the letter supplying module and comprises an air inlet pipe communicated with a filtering device, the filtering device is communicated with a vortex fan, the vortex fan is communicated with a blowing pipe, an air inlet pipe and an air outlet pipe are provided with a bypass decompression pipe respectively, and the bypass decompression valves adjust inhaling and blowing flow through throttle valves. The air inlet pipe is communicated with an inhaling pipe on an inhaling module of the separating mechanism of the letter supplying module, and an air blowing pipe is communicated with the air source connection port on the letter supplying module.

Description

technical field [0001] The invention relates to a blowing and suction system for separating and conveying letters, which belongs to the technical field of letter sorting and conveying. Background technique [0002] The automatic sorting equipment for letters is used to separate the letters one by one, and the letters are clamped by a pair of belts and then conveyed backwards. [0003] This automatic sorting equipment includes a letter supply module, see Figure 2-3 , a stack of letters stands upright on the letter supply belt 2, and moves forward along the direction of the letter supply belt under the double action of the letter supply push plate 3 and the letter supply belt 2 until the first letter touches the separation mechanism 1; the separation mechanism 1 The structure see Figure 4-7 , the separation mechanism 1 is provided with a suction module 101, the specific structure of the suction module 101 can be found in Figure 8 , including the suction pipe 101b and the ...

AI Technical Summary

Problems solved by technology

[0005] The technical problem to be solved by the present invention is: the letter supply module of the existing automatic sorting equipment, when the letter is pushed, it is easy to cause the distance between adjacent letters to be too small, that is, the letter is pressed too tightly, resulting in separation by the separation mechanism. Sometimes it is difficult to separate the single seal, or even stuck
