After separation block 7, paper feeding roller 5 continues to drive a piece of paper to enter paperboard upset lid 10 and upper slitter lid a piece of paper Paper feed channel 13 between 11, paper feed channel 13 is communicated with the shredded paper mouth 11a on upper slitter lid 11, therefore passes through paper feed channel 13 Guide effect can ensure that paper can stably enter in shredded paper mouth 11a and carries out shredded paper.When the front end of paper enter into broken In paper mouth 11a and when contacting with the paper shredding blade 2 rotating in shredded paper mouth 11a, due to taking paper needs, paper shredding blade speed is more than Paper feeding roller speed, paper shredding blade 2 can produce a driving force continuing to move along to paper, now makes under comprehensive active force The speed obtaining paper is more than the speed of paper feeding roller 5, leads to take the clutch driving link 4b on reel 4 to take off with clutch driven member 4a phase From, clutch driven member 4a no longer with taking reel 4 together to rotate, and still part is contacted with paper feeding roller 5 due to the end of paper, Therefore now drive clutch driven member 4a freely rotatable with respect to taking reel 4 by paper, the frictional force between paper feeding roller 5 and paper Relatively reduced so that paper more stably can carry out shredded paper completely into in shredded paper mouth 11a.

If now paperboard or mistake press reverse key, so that motor 1 is inverted, take reel 4 to reversely rotate, take reel 4 On take the clutch driving link 4b on reel to return to the driving inclined-plane bottom of clutch actuator, clutch actuator lose driving make With taking the clutch driving link 4b and clutch driven member 4a on reel to be separated, paper feeding roller 5 is freely rotatable, would not cause to take paper Paperboard at wheel.

Paper when entering in shredded paper mouth 11a and contacting with paper shredding blade 2, can cut to paper by the paper shredding blade 2 of rotation Broken.And when paper stuck between paper shredding blade 2 when, user can first stop shredder, is then lifted up positioned at casing 1 table again The outer end of the paperboard upset lid 10 at the breach 1a of face, paperboard upset lid 10 is turned out and beats with respect to its inner pin joint Open, the shredded paper mouth 11a on upper slitter lid 11 exposes outside, the paper in the stuck mouth 11a in shredded paper can directly be taken out by user, card After dead paper takes out, then paperboard upset lid 10 is covered back restart shredder again.

In addition, in order to prevent shredder from putting on paper disc no in the case of paper, putting paper disc and make with paper feeding roller directly contact Become paper feeding roller and put paper disc damage, the bottom that this automatic paper crusher passes through putting paper disc 3 arranges sensing chip 20 and grooved photoelectric transfer Sensor come to realize to put have or not on paper disc 3 paper placement detection.In the state of putting paper disc 3 no paper placement, sensing chip 20 It is rotated up under the active force of torsion spring, and so that the larger one end of sensing chip 20 is stretched out outside bar hole 3c, positioned at putting paper disc 3 bottom Trough type photoelectric sensor be not triggered, now can determine that and put on paper disc 3 no paper, even if shredder starts, motor two 17 also will not start, and put paper disc and also will not go up lift.And when there being paper to put into, due to the torsion very little of torsion spring, therefore paper meeting One end larger for sensing chip 20 is overcome the effect of torsion spring to rotate down around pin joint, the larger one end of sensing chip 20 is passed through Bar hole 3c to the rotated down putting paper disc 3, can pass through when turning to, when the larger one end of sensing chip 20, the bottom putting paper disc 3 And trigger trough type photoelectric sensor, now can determine that to put that paper is had on paper disc 3, motor 2 17 starts.

Specific embodiment described herein is only explanation for example to present invention spirit.The affiliated technology of the present invention is led The technical staff in domain can be made various modifications or supplement or replaced using similar mode to described specific embodiment Generation, but the spirit without departing from the present invention or surmount scope defined in appended claims.
