Description
Technical field
The utility model belongs to office equipment field more particularly to a kind of paper feeding mechanism.
Background technology
In existing presser type shredder, paper feed port is generally located on the center line of paper placement area, in paper feed port both sides
Paper feeding wheel is equipped with, paper is positioned on paper placement area, and paper is compressed by pressboard, what the paper feeding wheels of both sides compressed pressboard
Paper folds, and the fold line of paper is overlapped with the center line of paper, and both sides feed roller needs to bring the paper of half into respectively, that is, needs
It brings full size into and is sent into paper feed port, then enter in paper shredder and crush from paper feed port, could start to bring into next
Paper is opened, causes the problem of paper feeding speed is slow, shredded paper efficiency is low.
Therefore it is badly in need of a kind of to improve paper feeding speed to improve the paper feeding mechanism of shredded paper efficiency.
Utility model content
The purpose of this utility model is to provide a kind of paper feeding mechanism, it can be achieved that the quick paper feed of shredder, improves shredded paper
Efficiency and it is not easy paperboard.
The another object of the utility model is to provide that a kind of can be not easy that paperboard, paper feeding speed are fast, shredded paper is efficient broken
Paper machine.
The utility model provides a kind of paper feeding mechanism, including rack, is installed on putting cardboard, be installed in the rack
Paper-pressing part in the rack is arranged on the opposite feed roller of the paper feed port put on cardboard and position and to paper wall, institute
It states to put and paper placement area is formed on cardboard to place paper, the paper-pressing part is put positioned at described above cardboard, and the paper-pressing part is opposite
Cardboard folding is put to compress the paper put on cardboard in described, and the paper feed port is arranged on the one side of the paper placement area center line
And there is certain distance with the center line of the paper placement area, the feed roller is installed in the rack and positioned at the paper feed port
On one side away from center line, it is described support paper wall be located at the paper feed port close to the one side of center line and with feed roller cooperation
Form a paper-feeding passage, the feed roller is rotated and coordinated described is located at feed roller to the paper that paper wall compresses the paper-pressing part
The part of one side folds along the paper feed port and is conveyed into the paper feed port.
Compared with prior art, during the utility model paper feed, paper is pressed on and put on cardboard by paper-pressing part, due to paper feed port
There is certain distance with the position of feed roller arrangement and the center line of paper placement area, therefore the fold line of the paper not center line with paper
It folds, paper is divided into two parts by paper feed port, and the area of a portion is larger to be known as large area part, the area of another part
Smaller to be known as small area part, feed roller is located at one side of the paper feed port away from center line, therefore during feed roller rotation, in a collection of paper
Small area part first folds feeding paper feed port to movement at paper feed port and along fold line, and large area part is after thereafter by shredded paper
