The specific embodiment
Content of the present invention is easier to be expressly understood in order to make, and the below is according to specific embodiment and by reference to the accompanying drawings, and the present invention is further detailed explanation,
as shown in Fig. 1 ~ 8, a kind of automatic paper cutting device of multi-joint chain type paper bill printer, comprise stationary knife installing rack 13, moving knife installing rack 14, stationary knife 5, moving knife 6 with stationary knife 5 cooperations, the spacing guiding mechanism of moving knife and drive that moving knife 6 slides up and down on moving knife installing rack 14 and and stationary knife 5 coordinate the drive transmission device of realizing that cut paper moves, stationary knife installing rack 13 is fixedly connected with moving knife installing rack 14, stationary knife 5 is arranged on stationary knife installing rack 13, moving knife 6 is arranged on moving knife installing rack 14, be equipped with on stationary knife installing rack 13 and make stationary knife 5 have certain curvature and make stationary knife 5 bend towards gradually the bending structure of moving knife 6 one sides to the middle part of stationary knife 5 by the position, both sides of stationary knife 5, be provided with the middle part cutting edge face 6-1 lower than both sides position on moving knife 6.
As shown in Figure 1, the bending structure comprises a plurality of stationary knife bending screws 15, a plurality of stationary knife bending screws 15 are screwed on stationary knife installing rack 13, and be positioned at stationary knife 5 sides, and the nail tip section of a plurality of stationary knife bending screws 15 props up stationary knife 5, and the be screwed into degree of depth of each stationary knife bending screw 15 on stationary knife installing rack 13 increases gradually from stationary knife 5 positions, both sides to stationary knife 5 middle parts.
Certainly, also has the another one mode, a plurality of stationary knife bending screws 15 also can be screwed on moving knife installing rack 14 and be positioned at moving knife 6 one sides, and in this case, the be screwed into degree of depth of each stationary knife bending screw 15 on moving knife installing rack 14 reduces gradually from stationary knife 5 positions, both sides to stationary knife 5 middle parts.Above-mentioned dual mode is all to realize making stationary knife 5 to bend towards gradually moving knife 6 one sides by the position, both sides of stationary knife 5 to the middle part of stationary knife 5.
As shown in Figure 2, the spacing guiding mechanism of moving knife comprises the moving knife guide rail 7 that is arranged on moving knife installing rack 14, and moving knife 6 is sliding to be fitted in moving knife guide rail 7.
As shown in Figure 3, drive transmission device comprises motor 12, multi-stage speed-reducing gear train 10 and moving knife power transmission shaft 11, have chute hole 6-2 on moving knife 6, moving knife power transmission shaft 11 is fixedly connected on the perisporium of afterbody gear of multi-stage speed-reducing gear train 10, form the cam drive mode, motor 12 is flexibly connected with multi-stage speed-reducing gear train 10, and when motor 12 action, moving knife power transmission shaft 11 slides in chute hole 6-2.
As shown in Figure 3, moving knife guide rail 7 inner sleeves have preloading spring 8, and an end of preloading spring 8 is against on moving knife installing rack 14, the other end of preloading spring 8 compress moving knife 6 in case make moving knife 6 in the cut paper process with stationary knife 5 close contacts.
As shown in Figure 3, moving knife guide rail 7 is provided with two, is arranged on respectively the both sides of moving knife installing rack 14, and the dual-side of moving knife 6 is joined with two moving knife guide rails 7 are sliding respectively.
As shown in Fig. 4 ~ 6, cutting edge face 6-1 is the high V character form structures in middle low both sides, but is not limited to this.
As shown in Figure 3, Internal baffle 9 is installed on moving knife installing rack 14, multi-stage speed-reducing gear train 10 is arranged in Internal baffle 9.
The curvature of the bending of stationary knife 5 is 0.0125 m
-1, its radius of curvature is 8000mm, but is not limited to this.
The course of work of printer of the present invention is as follows:
As shown in Fig. 7,8, the bill printer 1 chain type paper 2 of packing into, start bill printer 1, require to carry out paper feed and print corresponding contents according to printing, after printing end, to the cut paper position, automatic paper cutting device 3 carries out the cut paper action to bill printer 1 with 2 paper feedings of chain type paper, chain type paper 2 is cut off by the specification of setting, lead paper and outer cover assembly 4 and guarantee that the chain type paper 2 that downcuts sends by the position of design.
The operation principle of cut paper of the present invention is as follows:
The rotation of the main shaft of motor 12 passes to each gear rotation of multi-stage speed-reducing gear train 10, and the rotating speed that reaches motor 12 slows down, simultaneously with the moment of torsion transmission and be amplified on the afterbody gear of multi-stage speed-reducing gear train 10.
By the circular motion that is connected to the moving knife power transmission shaft 11 on the afterbody gear, the chute hole 6-2 of two racetrack in lower end by moving knife 6 is converted into moving up and down of moving knife 6.
By the cooperation of moving knife guide rail 7 and moving knife 6, the left and right directions that moving knife 6 is moved up and down limits.
Because the lower end side locating hole of moving knife guide rail 7 is inserted in the screw surface that is screwed in the corresponding screwed hole of moving knife installing rack, the axis of all moving knife guide rail 7 relative lower end side locating holes can swing.
Moving knife 6 and stationary knife 5 guarantee to contact reliably in the shearing motion process because the effect of preloading spring 8 remains certain pretightning force.
When moving knife 6 moved upward, the cutting edge face 6-1 of moving knife 6 must be pressed the mode that point contacts with stationary knife 5 curved cutting edges to the centre by two ends, and pointwise is smoothly sheared, and shearing force is little, and otch is bright and clean; When the shearing motion that makes progress is completed, moving knife 6 moves downward, according to the shape of the stationary knife cutting edge of the cutting edge face 6-1 of moving knife 6 and the regulation curvature that is bent, the mode that the cutting edge face 6-1 of moving knife 6 and stationary knife 5 curved cutting edges must be contacted by point to two ends by the centre, the smooth-going separation of pointwise, one of self-assembling formation is from sharp effect, guaranteed the long-life of cutting knife, it has avoided cut paper burr, winding and paper jam phenomenon easily to occur, and the cut paper otch is bright and clean, cutting is reliable, has realized the multi-layered paper cutting.
Above-described specific embodiment; purpose of the present invention, technical scheme and beneficial effect are further described; institute is understood that; the above is only specific embodiments of the invention; be not limited to the present invention; within the spirit and principles in the present invention all, any modification of making, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
