Description
Technical field
The present invention relates to shredder field, especially a kind of shredder double blade cutting edge and its processing technology.
Background technique
Shredder is combed by blade, the paper of one group of rotation and drive motor forms.Paper is among the blade being mutually twisted
It is sent into, is divided into many tiny scraps of paper, to achieve the purpose that secrecy.Commonly crushing type shredder basic functional principle is
It is set on cutter shaft with cutting blade collocation spacer ring, drives two groups of parallel and relative rotation using motor and mate gear device
Cutter shaft pair, the paper passed through is cut into fragment using the shearing force of formation.
At present in industry, the cutting edge that cutting edge generally uses single side to put the first edge on a knife or a pair of scissors, generally by 2 single dege blade mirror symmetries
And it is superimposed to form V-shaped, achieve the effect that there are cutting edge in single dege blade two sides.The single dege blade being so superimposed, knife when superposition
There are gaps between piece and blade, and there are paper jam risks.Stack combinations at least need 2 blades, i.e. work in-process, need to process
2 blades, processing cost are higher.
Summary of the invention
The technical problem to be solved by the present invention is overcome the deficiencies in the existing technology, a kind of design is provided rationally, processing side
Just, it can effectively ensure that cutting edge intensity, avoid that cut paper holding paper occurs, production cost is effectively reduced, saves the shredded paper of operation resource
