Abstract
The utility model discloses a composite motion cutter mechanism of a digitally controlled paper cutter, which comprises a transmission pulley, a worm, a worm wheel and a cutting bed, wherein the transmission pulley is connected with a driving wheel of a motor, the worm is connected with a wheel shaft of a transmission belt, the worm wheel is meshed with the worm and the cutting bed is provided with a blade. A left slider in a left slideway and a right slider in a right slideway of the cutting bed are fixed on a frame of the paper cutter, which is above the cutting bed. The two slide ways are not in parallel to each other. An S point at the lower part of one side of the left slideway is connected with the worm wheel through a crank link mechanism. The blade of the composite motion cutter mechanism of the utility model horizontally moves and rotates to form a cutting angle. Therefore, the cutting force is obviously reduced so that the cut-in actions become stable. Thus, the cutting accuracy is improved and the automatically controlled paper cutting motion with high speed and high accuracy is realized.
Description
Technical field
The utility model relates to a kind of device of paper cutter, particularly a kind of compound motion cutter bed mechanism of numerical control slitter.
Background technology
The cutter bed of tradition paper cutter all adopts two suspension rods, simplex pull rod, flatly moving type motion, because shearing impact power was bigger when it cut, blade rust and relevant stressed member are damaged, to cut precision low thereby cause, flaws such as the antiquarian that promptly cuts is inconsistent, burr produce waste product then.Therefore, the cutter bed mechanism of traditional paper cutter is difficult to satisfy numerical control slitter to high speed, high-precision requirement.In order to realize high speed, high-precision automatic control cut paper motion, cutter bed mechanism is one of improved key device of paper cutter.
Summary of the invention
The purpose of this utility model provide a kind of have incision steadily, response speed is fast, cut the precision height, the numerical control slitter compound motion cutter bed mechanism of easy to adjust and reliable operation, with realize at a high speed, high-precision automatic control cut paper motion.
For achieving the above object, the technical solution adopted in the utility model is: a kind of compound motion cutter bed mechanism of numerical control slitter, comprise the drive pulley that connects the motor driving wheel, the worm screw that is connected with pulley shaft, and the worm gear of worm engaging, be provided with the cutter bed of blade, left slider in the left slideway of described cutter bed, the right slide block in the right slideway are fixed on the cut paper frame of cutter bed top, and two slideways are not parallel each other; The S point of described cutter bed left side slideway one side-lower is connected with worm gear by toggle.
In the such scheme, toggle comprises crank, the cutter bed pull bar that is connected with worm gear, is provided with adjusting screw(rod) between described crank and the cutter bed pull bar; Described drive pulley one side is provided with brake coupling; This brake coupling is a hydraulic cylinder.
The utility model is compared with traditional paper cutter bed motion, its beneficial effect is: because the cutter bed adopts the structure of composite motion, be that blade existing translation when cutting paper has the formation of rotation cutting angle again, therefore can significantly reduce the power of cutting, impulsive force when having reduced the blade incision, incision is become steadily, cut precision, further can prolong the service life of blade thereby improved.

Fig. 2 is the enlarged drawing of the toggle among Fig. 1.
Fig. 3 is the utility model compound motion cutter bed mechanism cut paper view.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
As shown in Figure 1, a kind of compound motion cutter bed mechanism of numerical control slitter, comprise the drive pulley 2 that connects motor 1 driving wheel, the worm gear 5 that meshes with 2 worm screws that are connected 4 of drive pulley, with worm screw 4, the cutter bed 6 that is provided with blade 7, left slider 8 on the cutter bed 6 in the left slideway 10, the right slide block 9 in the right slideway 11 are fixed on the cut paper frame of cutter bed 6 tops, and left slideway 10, right slideway 11 are not parallel each other; The S point of cutter bed 6 left slideway 10 1 side-lowers is connected with worm gear 5 by toggle I; The turning cylinder of worm screw 4 is fixed on bearing group 12,13 and 14; The turning cylinder of worm gear 5 is also fixed.
As shown in Figure 2, toggle I comprises crank 24, the cutter bed pull bar 20 that is connected with worm gear 5, and the crank axle 25 of crank 24 is connected with worm gear 5; One end of cutter bed pull bar 20 is connected with the S point of cutter bed 6, and the other end is provided with adjusting screw(rod) 22, and is locked by nut 21; Crank 24 is connected with check screw 26 by nut 23 with adjusting screw(rod) 22; Consider that blade 7 width after using one section period sharpening reduces, and in order to prevent that blade behind the sharpening, cutting edge from tilting, so be provided with the structure of above-mentioned adjusting screw(rod) 22 at cutter bed pull bar 20; Check screw 26 is parts that play overload protective function, it is broken when preventing that cutter bed 6 is hit overload in the course of the work, crank 24 is separated with cutter bed pull bar 20, and then can protect other part.
Technical scheme according to embodiment 1, described drive pulley 2 one sides also can be provided with brake coupling 3, this brake coupling 3 can be a hydraulic jack, its piston is provided with brake shoe with respect to drive pulley 2 one sides, when motor 1 starting and stopping, hydraulic cylinder is by the clutch to drive pulley 2 of the control section control piston brake shoe of numerical control slitter, thereby can reduce drive pulley 2 start-stop inertia to reduce the impact of tool setting bed 6 motions, improves the stationarity when cutting a sheet of paper.
As shown in Figure 3, operation principle of the present utility model is, for can cutter relieving bed 6 at the volley except glide along oblique line move, cut power and the impulsive force of the rotation that also has a trace when reducing to cut paper, thereby be designed to the left and right sides slideway 10,11 of cutter bed 6 not parallel, be that left slideway 10 inclination alpha and right slideway 11 angle of inclination beta are unequal, thereby make cutter bed 6 that rotational motion be arranged when gliding.When cutting, cutter bed 6 is under the drive of toggle I, on the one hand along the tiltedly translation down of S point, cutter bed 6 rotates around the S point again simultaneously, the first incision of blade 7 paper were piled up neatly 30 o'clock like this, had only the part on the left side to pile up neatly 30 with paper and contacted, the decline of ordering along with S, blade 7 rotates gradually, cutting angle γ reduces, and blade is sheared and cut off paper buttress 30, when blade 7 left sides almost contact with platen 31, cutting angle γ is reduced to zero, and the process of cutting is finished.
