Cutter provided by the invention changes turning to of drive 41 by the rotation direction of adjusting motor 31, can realize the conversion of the pattern of entirely cutting and hemisection pattern.Fig. 6 a is structural representation when movable blade is positioned at initial position in the time entirely cutting pattern according to the cutter of first embodiment of the invention, and Fig. 6 b is structural representation when movable blade is positioned at final position in the time entirely cutting pattern according to the cutter of first embodiment of the invention.Introduce the course of work in the time entirely cutting pattern of cutter provided by the invention below in conjunction with Fig. 6 a, Fig. 6 b.
As shown in Figure 6 a, under original state, movable blade 2 lays respectively at transfer passage both sides, the preset distance setting of being separated by with fixed blade 1.
As shown in Figure 6 b, when cutter is entirely cutting while starting cut paper under pattern, motor 31 drives drive 41 to rotate around fixed axis 42 with first direction by worm screw 32, the second post 432 butts of the first end in the oval hole 413 of drive 41 and driving-disc 43, driving-disc 43 rotates around fixed axis 42 with drive 41, now, distance between the drive post 433 of driving-disc 43 and the axle center of fixed axis 42 (being also the axle center of drive 41) is the first predetermined eccentric throw d1, drive post 433 drive embed wheel 44 on one side drive hole 61 in around self axis rotation, move to the direction near fixed blade 1 on one side, embed wheel 44 drives attached plate 6 to drive movable blade 2 to move to the direction near fixed blade 1 in the close direction moving process of fixed blade 1, first the guide portion 23 that is positioned at movable blade 2 two ends is contacted with fixed blade 1.Along with drive 41 is rotated further, the blade 21 of movable blade 2 and fixed blade 1 constantly contact movement, and when drive 41 rotates 180 while spending, movable blade 2 overlaps with fixed blade 1 completely, the concave indentation 24 that is movable blade 2 middle parts also overlaps with fixed blade 1, and printing paper is completely severed.
When the rotational angle of drive 41 is greater than after 180 degree, along with drive 41 is rotated further, embed wheel 44 on one side drive hole 61 in around self axis rotation, on one side to moving away from the direction of fixed blade 1, drive movable blade 2 to moving away from the direction of fixed blade 1, when drive 41 starts to rotate a circle from initial position (i.e. 360 degree), be reset to position shown in Fig. 6 a, cutter completes a cut paper action.
Fig. 7 is the structural representation while being positioned at final position according to the cutter of first embodiment of the invention movable blade when the hemisection pattern.Introduce the course of work when the hemisection pattern of cutter provided by the invention below in conjunction with Fig. 7.
As shown in Figure 7, in the time that cutter starts cut paper under hemisection pattern, motor 31 drives drive 41 to rotate around fixed axis 42 with the second direction contrary with first direction by worm screw 32, driving-disc 43 is with respect to drive 41 dislocation that rotates, the second post 432 butts of second end in the oval hole 413 of drive 41 and driving-disc 43, driving-disc 43 rotates around fixed axis 42 with drive 41, now, distance between the drive post 433 of driving-disc 43 and the axle center of fixed axis 42 (being also the axle center of drive 41) is the second predetermined eccentric throw d2, and d2<d1, drive post 433 drive embed wheel 44 on one side drive hole 61 in around self axis rotation, move to the direction near fixed blade 1 on one side, embed wheel 44 drives attached plate 6 to drive movable blade 2 to move to the direction near fixed blade 1 in the close direction moving process of fixed blade 1, because the radius of gyration of the drive post 433 of driving-disc 43 now reduces, therefore the drive post 433 of driving-disc 43 drives embedding wheel 44 to diminish with respect to the displacement of fixed blade 1, when drive 41 rotates 180 while spending, the blade 21 of movable blade 2 overlaps with fixed blade 1, and the concave indentation 24 at the middle part of movable blade 2 and the fixed blade preset distance of being still separated by, therefore printing paper middle part is not cut off.
When the rotational angle of drive 41 is greater than after 180 degree, along with drive 41 is rotated further, embed wheel 44 on one side drive hole 61 in around self axis rotation, on one side to moving away from the direction of fixed blade 1, when drive 41 starts to rotate a circle from initial position (i.e. 360 degree), movable blade 2 is reset to initial position, and cutter completes a cut paper action.
Cutter provided by the invention comprises fixed blade and movable blade assembly, wherein movable blade assembly comprises movable blade, driven unit and at least one transmission component, wherein transmission component comprises drive, driving-disc, and embedding wheel, drive and driven unit are in transmission connection, on drive, be provided with a circular hole and an oval hole, be provided with and circular hole and oval hole peg graft respectively the first post and the second post that coordinate in a side of driving-disc, be provided with and embed the peg graft drive post that coordinates of wheel at the opposite side of driving-disc, embedding wheel pegs graft and coordinates with the attached plate that is connected with movable blade.
In the time that the motor of driven unit rotates with direction initialization, driving drive is rotated in a first direction, the second post butt of the first end in the oval hole of drive and driving-disc, now the axle center spacing distance of drive post and drive is the first predetermined eccentric throw d1, the drive post of driving-disc drives the displacement that embeds the relative fixed blade of wheel drive movable blade can make the blade of movable blade overlap completely with fixed blade, entirely cuts thereby realize, in the time that the motor of driven unit rotates with the direction contrary with direction initialization, drive drive to rotate with the second direction contrary with first direction, driving-disc 43 is with respect to drive 41 dislocation that rotates, the second post butt of second end in the oval hole of drive and driving-disc, now the axle center spacing distance of the drive post of driving-disc and drive is the second predetermined eccentric throw d2, and d2<d1, therefore, the drive post of driving-disc drives to embed to take turns and drives movable blade to reduce with respect to the displacement of fixed blade, the blade of movable blade can not be overlapped completely with fixed blade, thereby realize hemisection.
Cutter provided by the invention turns to adjust turning to of drive by what adjust motor, can automatically realize the conversion of the pattern of entirely cutting and hemisection pattern, pass through hand disassembly screw with cutter of the prior art, adjust movable blade and realize and entirely cutting or hemisection pattern photograph ratio with respect to the position of fixed blade, cutter ease for use provided by the invention is strong.
