Embodiment Construction

[0015] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0016] Such as image 3 and figure 2 as shown in figure 1 On the basis of the structure of the electric shredder shown, a lifting controller 12 and a sensor 13 are added. The lifting controller is installed at the bottom of the platen 14, and the sensor is installed at the paper inlet of the platen 14; in order to facilitate those skilled in the art to understand this The technical solution of the invention, this embodiment takes the lifting controller 12 as the electromagnet 26 and the sensor 13 as the photoelectric sensor 21 to specifically illustrate the technical solution of the present invention. Before the file is shredded, the photoelectric sensor 21 sends an electric signal, which is amplified by the signal amplifier ci...

Abstract

The invention relates to an electric shredder which comprises a singlechip, a positive rotation drive circuit, a reverse rotation drive circuit, a motor, a sensor and a lifting controller, wherein the singlechip is connected with the positive rotation drive circuit and the reverse rotation drive circuit which are simultaneously connected with the motor; the lifting controller is arranged at the bottom of a pressboard, and the sensor is arranged at a paper feeding hole of a press board of the shredder and connected with the singlechip. The press board is far from a paper feeding roller when no paper needs to be shredded, the sensor sends a signal to the singlechip when paper needs to be shredded, the singlechip sends a control signal to the lifting controller according to a set command, and the lifting controller releases fixation to the press board and puts the paper to be shredded to be close to the paper feeding roller by utilizing the force of a spring, thereby the shredder conveniently realizes automatic paper feed, reduces the paper shredding operation for operators and enhances the work efficiency of the operators.

Description

technical field [0001] The invention belongs to the field of electric paper shredders, in particular to an electric paper shredder whose paper feeding port can be automatically opened or closed. Background technique [0002] A paper shredder is a daily office item that can quickly shred confidential documents. Such as figure 1 As shown, the traditional automatic feeding type paper shredder is made up of paper feed roller 11, platen 14, motor 18, spring 17, transmission belt 15 and paper shredder knife 16, when using, the document is placed on the platen 14, start The power supply of the paper shredder, the motor 18 drives the paper shredder knife 16 in the paper shredder to rotate through the transmission belt 15, the spring 17 supports the paper platen, and supports the documents on the paper platen to contact with the paper feed roller, and the paper feed roller 11 rotates the document The pages are fed into the shredder, and the shredder knife 16 shreds the file.
