The specific embodiment
In order to understand the technical solution of the utility model better, below by embodiment particularly and be described in detail in conjunction with the accompanying drawings:
See also Fig. 1 and Fig. 2, the top of die-cutting machine is provided with the upper mounting plate 11 that is fixed, and the below of die-cutting machine is provided with by the lower platform that can move up and down 12 of toggle link drive mechanism, the following transverse plane of upper mounting plate 11 is provided with cross cutting knife plate (not shown), and the bottom surface of lower platform 12 is uniform fixes four first little (not shown).
The toggle link driving mechanism that is used for automatic die cutter of the present utility model is connected between lower platform 12 and the base 10, and first of the relative lower platform 12 little axle is fixed with four second little axles 100 on this base 10.The toggle link driving mechanism comprises a bent axle 20, four connecting rods 23, four upper elbow levers 21 and four lower elbow levers 22, wherein the main shaft of bent axle 20 middle part is provided with a worm gear 24 and is respectively equipped with a pair of crank throw on the main shaft of the both sides of worm gear 24, four connecting rods 23 are fixed on the crank throw separately, and the outer end of every connecting rod 23 is respectively simultaneously hinged with an end of an end of a upper elbow lever 21 and a lower elbow lever 22, four upper elbow lever 21 1 ends are separately installed with upper elbow lever bearing shell 210, and upper elbow lever 21 and the first little axle that is positioned at lower platform 12 bottom surfaces are rotationally connected; The other end of four lower elbow levers 22 is separately installed with lower elbow lever bearing shell 220, and lower elbow lever 22 and the second little axle 100 that is positioned on the base 10 are rotationally connected.
The component parts of the toggle link driving mechanism that is used for automatic die cutter of the present utility model is consistent with the toggle link driving mechanism component parts of prior art, but the toggle link driving mechanism that is used for automatic die cutter of the present utility model can make the paper product of cross cutting knife plate contraposition on lower platform that is fixed on the upper mounting plate realize shearing application of force cross cutting by two kinds of technical schemes.
See also Fig. 3 a and Fig. 3 b, the first kind of technical scheme that is used for the toggle link driving mechanism of automatic die cutter of the present utility model is: two crank throws 201,202 of every pair of crank throw are provided with dorsad with 180 °, the alignment of shafts O of bent axle 20 is lower than hinged center G, the D of connecting rod 23 and upper elbow lever 21 and lower elbow lever 22, and promptly the horizontal level of the alignment of shafts O of bent axle 20 is lower than the horizontal level one coverage Δ B of hinged center G, the D of connecting rod 23 outer ends on every pair of crank throw and upper elbow lever 21 and lower elbow lever 22.The hinged upper elbow lever 21 in two connecting rod outer ends is respectively A, B with the pin joint of lower platform 12 front and back ends, and lower elbow lever 22 is respectively H, E with the anchor point of base 10 front and back ends.Do to rotate at the uniform velocity continuously when bent axle 20 is driven by active force, by connecting rod 23, upper elbow lever 21 and lower elbow lever 22 are swung, thereby formed moving up and down of lower platform 12.When turning round to the C1 position, crank throw 202 (sees Fig. 3 a), upper elbow lever 21 is the extreme higher position with the pin joint B of lower platform 12 rear ends, this moment, another crank throw 201 was in the F1 position, because OD＞OG, so BE＞AH has a difference in height Δ D between pin joint A, the B of upper elbow lever 21 and lower platform 12 front and back ends; In like manner, when crank throw 201 turned round to F2 (seeing Fig. 3 b) position, upper elbow lever 21 was the extreme higher position with the pin joint A of lower platform 12 front ends.A cycle of activity, formed lower platform 12 table tops from A-P to the shearing application of force cross cutting of page.
See also Fig. 3 c and Fig. 3 d, the second kind of technical scheme that is used for the toggle link driving mechanism of automatic die cutter of the present utility model is: two of every pair of crank throw crank throws 201,202 all are provided with dorsad in the mode less than 180 ° on the bent axle 20, and promptly the angle α between the vertical join line of the spindle centerline of center line of these two crank throws 201,202 and bent axle is less than 180 °; The alignment of shafts O of bent axle 20 and connecting rod 23 are in same horizontal level with hinge joint center C, the D of upper elbow lever 21 and lower elbow lever 22.When crank throw 202 turns round to C1 (seeing Fig. 3 c) position, upper elbow lever 21 is the extreme higher position with the anchor point B of lower platform 12 rear ends, this moment, another crank throw 201 was in the F1 position, because OD＞OG, so BE＞AH has a difference in height Δ D between anchor point A, the B of upper elbow lever 21 and lower platform 12 front and back ends; In like manner, when crank throw 201 turned round to F2 (seeing Fig. 3 d) position, upper elbow lever 21 was the extreme higher position with the anchor point A of lower platform 12 front ends.A cycle of activity, formed lower platform 12 table tops from A-P to the shearing application of force cross cutting of page.
Cross cutting pressure can calculate by the geometric figure among Fig. 4:
Δ F=Δ L/L=(Δ H/tg θ)/L, wherein,
θ be upper elbow lever 21 with the anchor point A of lower platform 12 front and back ends, when B is up to the extreme higher position, the front and back pivot angle of lower platform 12;
L is the maximum length of paper product;
Δ L is that upper elbow lever 21 is with the anchor point A of lower platform 12 front and back ends, paper product contacted the length of the cross cutting edge of a knife when B was up to the extreme higher position;
Δ H is a upper elbow lever 21 and the anchor point A of lower platform 12 front and back ends, the shearing thickness of paper product when B is up to the extreme higher position;
Get L=1200mm, Δ H=0.3mm, θ=0.06 °
ΔF＝(0.3/tg0.06)/1200＝23.87％
From calculating, the maximum norm shear force of this die-cutting machine is reduced to 23.87% of original cross cutting power.
Above-mentioned two kinds of technical schemes all make lower platform be slightly to wave shape up, even the front end of lower platform table top and rear end successively do not enter the extreme higher position simultaneously, can make the paper product of cross cutting knife plate contraposition on lower platform that is fixed on the upper mounting plate realize shearing application of force cross cutting, the cross cutting power of this mode reduces significantly than the cross cutting power of prior art, and then the physical dimension of die-cutting machine can not increased to some extent along with the paper product of the big specification of cross cutting.
Those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the utility model, and be not to be used as qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in claims scope of the present utility model variation, the modification of the above embodiment.
