The length of half identical whole fixed blade during helical form cutting edge rotation half-turn to two circle.
Transmission mechanism, rotating blade, fixed blade, support, position sensor, control system are installed on the base, and shell is provided with protective cover, and Hall element is housed in the cover.When the protective cover of paper cutting apparatus was opened, the Hall element signal was to control system, and control system is sent signal quits work rotating blade immediately, finishes when protective cover is closed again to reset.
Paper cutting apparatus is equipped with black mark sensor, and black mark sensor is finished accurate location by the black mark on the identification paper, realizes accurately cutting a sheet of paper.Paper cutting apparatus has a plurality of black mark installation of sensors position, makes paper cutting apparatus can be suitable for different paper.
Begin rotation (the paper delivery drive motors stops simultaneously) behind the driving signal that the drive motors receiving control system sends, by transmission mechanism driven rotary blade rotation, make the occlusal position continuous moving of rotating blade and fixed blade realize automatic cutting, cut a sheet of paper the position sensor feedback signal installed on rotating blade one end when finishing to control system, control system sends a signal to drive motors again, drive motors driven rotary blade is resetted, finish automatic cutting one time.
One end of rotating blade is equipped with operating grip, and cutting a sheet of paper of paper cutting apparatus namely can be finished in manual operation, also can realize automation control.Can't automatic cutting or during some special circumstances when paper cutting apparatus occurring, can finish and cut a sheet of paper or rotating blade is resetted by rotating the handle of installing on the rotating blade.
The beneficial effects of the utility model are that the structure of rotating blade and fixed blade and cutting guarantee to cut a sheet of paper accurately and reliably.Be applicable to the paper cutting apparatus of printer, paper or the bill of having printed data can be downcut, thereby make printer have the function of automatic cutting.Can be automatically with manually combine, finish and cut a sheet of paper or rotating blade is resetted by rotating the handle of installing on the rotating blade.
Description of drawings:
Below in conjunction with accompanying drawing and specific embodiments the utility model is described in further detail.
Fig. 1 is the 3D view of the utility model device.
Fig. 2 is for removing the 3D view of shell, protective cover and handle.
Fig. 3 is the top view of rotating blade, fixed blade and support assembling.
The specific embodiment
The below is according to Fig. 1-3 explanation the utility model embodiment, and present embodiment is the application example that paper cutting apparatus is installed in printer end.
As depicted in figs. 1 and 2, paper cutting apparatus is made of shell 1, protective cover 2, black mark sensor 3, handle 4, Hall element 5, left socle 6, rotating blade 7, fixed blade 8, right support 10, rotating blade position sensor 11, elastic bar 12, control system 13, base 14, drive motors 15, transmission mechanism 16 etc.Rotating blade 7 and fixed blade 8 that transmission mechanism 16, rotating blade position sensor 11, handle 4 are installed are installed on the base 14 by left socle 6, right support 10, Hall element 5 is contained in an end of protective cover 2, protective cover 2 is installed on the shell 1, and shell 1 and base 14 are fixed by screw attachment.Fixedly cutting edge 8a on the fixed blade can contact with rotating blade 7 all the time, and is closely reliable for making this contact, connects with right support 10 by elastic bar 12 at an end of fixed blade 8.A plurality of black mark installation of sensors position is arranged on the protective cover 2, and black mark sensor 3 is followed according to the width of paper and is installed on the suitable position.
Printed the paper of data or bill and 9 entered paper cutting apparatus along the path, do not received when cutting a sheet of paper order when control system 13, paper cutting apparatus is in initial position, and this moment rotates blade 7a and counteredge 8a has enough gaps to be convenient to paper delivery; After control system 13 receives the order of cutting a sheet of paper, paper position signal according to black mark sensor 3 feedbacks, send after treatment instruction, make paper or bill stop motion, drive motors 15 begins to rotate simultaneously, transmission mechanism 16 passes to rotating blade 7 with rotatablely moving of drive motors 15, rotating blade 7 begins to rotate, make rotation blade 7a begin gradually to contact with counteredge 8a and contact point is moved from left to right, finish the signal of rear rotating blade position sensor 11 perception of cutting a sheet of paper and pass to baking system 13, send instruction after control system 13 is processed through signal and make paper cutting apparatus get back to initial position, finish once and cut a sheet of paper.
