Description
Technical field
The present invention and a kind of printer auxiliary equipment, particularly a kind of paper-cutting device for printer.
Background technology
Along with the modern development of China, at industry-by-industry, such as instrument and meter, supermarket, convenience store, postal service, bank, tobacco monopolization, public utilities are checked meter, the field such as movable police system, mobile government system gradually adopts Possum, and the printer be arranged on Possum must with automatic paper-cutting function.At present, the cut paper structure of printer is divided into two kinds usually.The first is flat knife cut paper structure, its structure be moving knife and stationary knife shear and withdrawing time cutting edge between be plane contact, this design result in moving knife and stationary knife, and mutually to overlay power larger, easily there is face contact wear in moving knife and stationary knife, service life is shorter, in addition, also require that the installation quality of fit of moving knife and stationary knife is higher; The second is rotary paper-cutting cutter cut paper structure, it mainly adopts motor by multi-stage gear group or worm and gear combination deceleration rotary cutting, moving knife and stationary knife are sheared and withdrawing process is point cantact, the power that overlays applied between moving knife, stationary knife is very little, therefore the wearing and tearing of moving knife and stationary knife reach minimum, cutter life is longer, but the cut paper ability of this cut paper structure is less, be difficult to the paper that shearing thickness is larger, because the static distance of moving knife and stationary knife is less, easily occur the situation of paperboard, fault rate is higher.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of paper-cutting device for printer, has long service life and higher cut paper ability, failure rate is low.
In order to solve the problems of the technologies described above, a kind of paper-cutting device for printer of the present invention, comprise a left side, right-cut tool support, left, right-cut tool support is provided with the stationary knife group and movable cutter set of working in coordination, described stationary knife group is provided with ledger-plate, described movable cutter set two ends respectively with a left side, the pivot joint of right-cut tool support, the swinging end of movable cutter set is provided with the cutting blade with this ledger-plate corresponding matching, the moving knife sword lateral inclination of described cutting blade is arranged, ledger-plate has stationary knife sword, the transverse projection of this moving knife sword overlaps with the transverse projection of stationary knife sword, wherein the transverse projection of moving knife sword is circular arc, the pivot joint center superposition at its center of circle and movable cutter set two ends.
As the improvement of technique scheme, arc-shaped curvature portion is provided with on described cutting blade, with the close one end of ledger-plate, described moving knife sword extends to arc-shaped curvature portion along cutting blade shape, on moving knife sword, one end close with stationary knife sword contact with described stationary knife sword, and the transverse projection of described moving knife sword overlaps with the transverse projection of stationary knife sword.
As the improvement of technique scheme, the cutting angle of described stationary knife sword is right angle or acute angle.
As the improvement of technique scheme, described stationary knife group and movable cutter set make both keep in touch by blade by elastic mechanism.Described elastic mechanism is extension spring or torsion spring.
As the improvement of technique scheme, described movable cutter set bottom is provided with horizontal moving knife paper-finding frame, and this moving knife paper-finding frame is arranged with the paper guiding sheet tilted to paper feed direction, and this paper guiding sheet end edge is near described moving knife sword.
As the improvement of technique scheme, be provided with paper-finding frame above described stationary knife group, stationary knife group be provided with the stationary knife lateral paper guide relative with paper-finding frame on this, this stationary knife lateral paper guide tilts to be clamped on stationary knife seat by ledger-plate.
As the improvement of technique scheme, the outbound course of described stationary knife group and movable cutter set is provided with lower lateral paper guide, and described lower lateral paper guide is positioned at below movable cutter set.Go back holder housing between described left and right cutter supporter, described stationary knife group and movable cutter set are arranged in this housing.
The invention has the beneficial effects as follows: in this paper-cutting device for printer, movable cutter set is articulated between left and right cutter supporter, cutting blade is arranged at the swinging end of movable cutter set, cut off by the staggered scraps of paper be clipped between the two that make that are dynamic, stationary knife sword when movable cutter set swings, because movable cutter set adopts swing mode to cut the scraps of paper, its amplitude of fluctuation is larger, the momentum of cutting blade motion is larger, and the ply of paper that once can cut off is more, improves the ability to work of paper cutter; On the other hand, moving knife sword can reach larger distance with stationary knife sword when being separated, and avoids and encounters moving knife sword or stationary knife sword when paper exports and the phenomenon that occurs paperboard.And, the transverse projection of moving knife sword overlaps with the transverse projection of stationary knife sword, the transverse projection of moving knife sword is circular arc, the pivot joint center superposition at its center of circle and movable cutter set two ends, this architectural feature makes movable cutter set swing moving knife sword and stationary knife sword when cutting and remain laminating in working angles, ensures cutting effect, and avoids the danger of touching cutter, reduce the wearing and tearing of blade, extend the service life of paper cutter.
