Abstract
The utility model discloses a cutting knife device in the stenograph, which comprises a machine frame (1); a guide groove (2) fixed on the machine frame; a screw groupware (3) arranged in the guide groove; an electric motor transmission component (5) driving the screw rotating; a cutting knife component (4) which is driven by the screw component and slides along the guide groove; the utility model is characterized in that: the utility model also comprises a cutting knife rack (7) parallel to the guide groove which is arranged on the machine frame, and a gear (45) joggled with the rack and arranged on the cutting knife component. As a circular knife blade is additionally arranged on the traditional cutting knife in the utility model For radial rotation, compared with the prior art, the cutting knife can produce high speed rotation when moving in a straight line so as to form a motion cutting, with high cutting off efficiency and tidy and nice cutting profile.
Description
Technical field
The utility model relates to duplicating machine, relates in particular to the duplicating machine cutter sweep.
Background technology
The cutter sweep of tradition duplicating machine is divided into two kinds: one, scissor cutting knife, and its advantage is simple in structure, and is with low cost; Shortcoming is stuck easily, and it is higher to shear fault rate; Two, roller cutting knife, it rotates by the driven by motor screw rod, blade produces mobile with the rotation of screw rod, the cutting paper, the advantage of roller cutting knife is that sound is less, easily processing, and shortcoming is because the rotation of cutter when rolling is to be close to the subsides shear surface to realize, the situation of or not when changeing when often occurring is so it is higher to shear fault rate.
The utility model content
In view of this, the purpose of this utility model is to solve the technical problem that prior art exists, and proposes a kind of easy and simple to handle, duplicating machine cutter sweep that cutting efficiency is high.
The technical scheme that the utility model proposes is: a kind of duplicating machine cutter sweep, comprise frame, be fixed in guide groove on the frame, be located at screw arbor assembly in the guide groove, drive motor transmission component that screw rod rotates and drive by described screw arbor assembly, cutter assembly along described guide groove slides is characterized in that: comprise that also parallel described guide groove is located at the cutting knife tooth bar on the frame and is located on the described cutter assembly and described tooth bar meshed gears.
Described cutter assembly comprises Cutter apron, and the one side is provided with a pin that snaps in the screw rod; Opposite side is provided with one, is connected with cutting knife, gear, cutting knife spring and cutter supporter in turn on the described axle, and described cutter supporter is fixed by screw and Cutter apron.
In an embodiment of the present utility model, also comprise and be located at frame one end, make the travel switch of described cutter assembly reversion.
The utility model has increased the radially rotation of circular shear blade on traditional cutting knife basis, compared with prior art, cutting knife produces rotation at a high speed when straight line moves, form scroll-diced, cuts off efficient height, tangent plane neat appearance.

Fig. 2 is the schematic diagram that the utility model guide groove, screw arbor assembly and cutter assembly cooperate;
Fig. 3 is the utility model cutter assembly and the schematic diagram that cooperates of tooth bar;
Fig. 4 is for being the utility model work schematic diagram.
The specific embodiment
For making the purpose of this utility model, technical scheme, advantage clearer and more definite, clear, be described in further detail below in conjunction with the specific embodiment and accompanying drawing.
As shown in Figure 1, the duplicating machine cutter sweep that the utility model proposes comprises frame 1; Be fixed in guide groove 2 on the frame by screw; Be located at the screw arbor assembly 3 in the guide groove; Drive the motor transmission component 5 that screw rod rotates; With drive the cutter assembly 4 that slides along described guide groove by described screw arbor assembly; Also comprise parallel described guide groove 2, be located at the cutting knife tooth bar 7 on the frame and be located on the described cutter assembly 4 and described tooth bar 7 meshed gears 45.
As depicted in figs. 1 and 2, cutter assembly 4 comprises Cutter apron 41, the one side is provided with a pin 46 that snaps in the screw rod, opposite side is provided with one 47, be connected with round cutter 42, gear 45, cutting knife spring 44 and cutter supporter 43 in turn on the axle 47, cutter supporter 43 both sides are provided with through hole, and fixing by screw and Cutter apron 41.Gear 45 and tooth bar 7 engagements, when gear 45 when tooth bar rotates, drive cutting knife and rotate, as shown in Figure 3.
One end of frame also is provided with and forms switch 8, has limit sensors on it, and travel switch 8 can make cutter assembly 4 along the guide groove reversion.The other end of frame is provided with location switch, and when the cutter assembly reversion put in place, motor stopped operating.
Fig. 4 is the utility model work schematic diagram.During work, when receiving, cutter motor shears instruction, even motor is applied in 12V voltage, the high-speed counterclockwise rotation of motor, and the screw rod in the rotation guide slot rotates, because the pin on the cutter assembly 4 is stuck in the tooth of screw rod, thereby the drive cutter assembly moves along the guide groove straight line, at this moment, directly promote round cutter 42 motions on the Cutter apron, in-line gears 45 on the round cutter 42 and tooth bar 7 engagements, produce rotation thus, like this round cutter not only straight line move, and produce rotation, form scroll-diced.
When cutting knife 42 moves to the terminal of guide groove 2 and touches limit sensors 8, the cutter motor counter-rotating, cutting knife moves rapidly along former route, and up to being activated to bit switch, cutter motor stops operating, and waits for next shearing instruction.
The utility model increases the radially rotation of circular shear blade on the basis of traditional round cutter, make it produce rotation at a high speed when straight line moves, and forms scroll-diced, is beneficial to cut-out more, trims edition paper.
Though the utility model is described with reference to above-mentioned better embodiment; but those skilled in the art will be appreciated that; above-mentioned better embodiment only is used for illustrating the utility model; be not to be used for limiting protection domain of the present utility model; any within spirit of the present utility model and principle scope; any modification of being done, equivalence replacement, improvement etc. all should be included within the rights protection scope of the present utility model.
