In a specific embodiment of the present invention, middle side part all was provided with indication by nip 9 before and after described binary channels was gone into paper safety cover plate 2 upper surfaces.Thereby conveniently push.
In a specific embodiment of the present invention, the cross section of described paper inlet 11 is semicircle, and described shake-up parts 21 are to touch cam.
In a specific embodiment of the present invention, described novel double-channel paper-feeding safety structure of paper shredder also comprises the paper sheet thickness detection device (not shown), and described paper sheet thickness detection device is installed in the described paper inlet 11.When being installed to shredder, checkout gear can be connected with the shredder control circuit, thereby can realize protection according to the break-make of going into paper quantity control circuit that detects.When common field, can only need one group of paper sheet thickness detection device (light-operated or touch pole), go into paper safety cover plate 2 by binary channels and open formed two paper of going into of going into the paper passage but then need two groups of paper sheet thickness detection devices to be respectively applied for detection at non-common field at paper inlet 11.
In a specific embodiment of the present invention, described binary channels is gone into paper safety cover plate 2 middle parts and is also had into CD passage 19, describedly goes into CD passage 19 and is positioned at described shredded paper cutter shaft top.Promptly go into CD passage 19 and be communicated with paper inlet 11, the width of going into CD passage 19 is generally 1.2mm, the long 150mm that is generally, thereby when not opening binary channels and go into paper safety cover plate 2, by pressing the power switch that is provided with on the shredder loam cake 1, going into CD passage 19 can broken CD or card, and go into paper safety cover plate 2 when opening when binary channels, go into CD passage 19 owing to go into that paper safety cover plate 2 rotates thereby not above the shredded paper cutter shaft with binary channels, inwall by paper inlet 11 blocks, can't go into CD passage 19 broken CD or cards by this, and can shredded paper by the paper passage of opening of going into.
Preferably, described shredder loam cake 1 also has into card path, and described shredder also comprises broken card cutter shaft, describedly goes into card path and is positioned at described broken card cutter shaft top.The width of going into card path is generally 1.2mm, the long 150mm that is generally, when wanting card such as broken CD or credit card, need not to open binary channels equally and go into the power switch that paper safety cover plate 2 just can directly be pressed setting on the shredder loam cake 1, insertion CD or card are pulverized in going into card path, and go under the situation of paper safety cover plate 2 opening binary channels, still can in going into card path, insert CD or card is pulverized.
See also Fig. 3～Fig. 6, when above-mentioned each parts are assembled, to touch safety switch 3 is fixed on first shaft seat 12, the rotating shaft 14 of first shaft seat 12 and second shaft seat 13 is penetrated the shredder binary channels respectively goes in the axis hole 6 of first side panel 4 on the paper safety cover plate 2 and second side panel 5, with screw first shaft seat 12 and second shaft seat 13 are fixed in the shredder loam cake 1 again, assembling position as shown in Figure 4, as shown in Figure 5, cross section is as shown in Figure 6 after assembling.
During use, see also shown in Figure 6, when the shredder binary channels is gone into paper safety cover plate 2 when being in closed condition, convex tendon 8 is positioned at standby groove 17, the shake-up cam that the shredder binary channels is gone on the paper safety cover plate 2 does not contact the contact 18 of touching safety switch 3 this moment, owing to touch the power supply of safety switch 3 control shredders, this moment, shredder was in off-position, paper inlet 11 is in closed condition, can guarantee the safety to the person when therefore being in this state.Partial enlarged drawing as shown in Figure 7.At this moment, can go into CD passage 19 or go into broken CD or card in the card path by pressing the power switch that is provided with on the shredder loam cake 1.
In the time will carrying out shredded paper, press the shredder binary channels and go into one of them indication on paper safety cover plate 2 both sides by nip 9, the shredder binary channels guiding muscle 22 of going into paper safety cover plate 2 forms one with paper inlet 11 (semicircle opening) and goes into the paper passage like this, the high point of cam 7 one ends that the shredder binary channels is gone on the paper safety cover plate 2 can be pushed shake-up safety switch 3 this moment, promptly touch cam extruding contact 18, thereby connection power supply, make whole shredder be in "on" position, this moment, convex tendon 8 was arranged in one of them work groove 16, user this moment can go into the paper passage of going into that the paper safety cover plate opens for 2 times by the shredder binary channels and carry out shredded paper; As shown in Figure 8.At this moment, simultaneously broken CD or card in going into card path, but can not be in going into CD passage 19 broken CD or card go into paper safety cover plate 2 with binary channels and rotate thereby not above the shredded paper cutter shaft, blocked because go into CD passage 19 by the inwall of paper inlet 11.
Go into the paper passage as what will use another side, see also Fig. 9, press the shredder binary channels and go into the indication of paper safety cover plate 2 another sides by nip 9, the shredder binary channels guiding muscle 22 of going into paper safety cover plate 2 forms another with paper inlet 11 (semicircle opening) and goes into the paper passage like this, in like manner, the shredder binary channels is gone into the cam of paper safety cover plate 2 can push shake-up safety switch 37 this moments, promptly touch the high point of cam 7 other ends extruding contact 18, thereby connection power supply, make whole shredder be in "on" position, this moment, convex tendon 8 was arranged in another work groove 16, and the user can carry out shredded paper by the paper passage of going into that the shredder binary channels is gone under the paper safety cover plate 2 this moment.
In working order down, have when leaveing no choice but the product of mincing and entering, will rotate binary channels and go into paper safety cover plate 2, described shake-up cam acts on the contact 18 of described shake-up safety switch 3, thereby closes described shake-up safety switch 3; Going into paper safety cover plate 2 in described shredder binary channels closes in the closed procedure, the shake-up cam of described cam 7 acts on the contact 18 of described shake-up safety switch 3 once more, thereby close described shake-up safety switch 3, that is to say, thereby the cam 7 that the shredder binary channels is gone on the paper safety cover plate 2 is pushed the break-make of the contact 18 control shredder power supplys of described shake-up safety switch 3 by touching cam.
To sum up, novel double-channel paper-feeding safety structure of paper shredder design of the present invention is ingenious, easy to use, has security, economy.
In this specification, the present invention is described with reference to its certain embodiments.But, still can make various modifications and conversion obviously and not deviate from the spirit and scope of the present invention.Therefore, specification and accompanying drawing are regarded in an illustrative, rather than a restrictive.
