Description
Technical field
The utility model relates to roll web flexographic printing wire stabbing train line, particularly a kind of binding line thin-book longitudinally cutting device.
Background technology
The flexographic printing train line promptly is whole crosscut and rip cutting operation through folding, behind flat, is cut to the thin basis of predetermined dimension.Wherein rip cutting direction is the streamline length direction along train line, and transverse direction is the width along streamline.
In the rip cutting operation, vertically cutting thin longitudinal knife (upper slitter), the following cutter interoperation of originally leaning on finishes, following cutter is horizontally fixed on the rack table, several longitudinal knife is installed on the main shaft that is arranged on rack table top, the main shaft section is circular, and longitudinal knife inclination certain angle, main shaft are inclined relative to horizontal the rectilinear motion up and down of certain angle under the effect of driving mechanism, and the edge of a knife of longitudinal knife is finished the rip cutting operation with the edge of a knife closure of following cutter from the bottom to top gradually.But several longitudinal knife is cut in thin this process simultaneously can produce very big power, because the restriction of main axis stiffness can produce bending when cutting book, drives longitudinal knife and twists, and makes book back breach, influence books quality and aesthetic measure, even produces and bump cutter, the damage blade.The workman often need carry out maintenance activity, has reduced efficient, has increased maintenance cost.
Summary of the invention
The utility model provides a kind of not yielding at above-mentioned the deficiencies in the prior art, can reduce thin this longitudinal cutting device that longitudinal knife damages.
The technical solution of the utility model is achieved in that
A kind of binding line thin-book longitudinally cutting device, this device comprises the crossbeam and the axis of guide of big rigidity, linear bearing and crossbeam driving mechanism, the axis of guide is inclined relative to horizontal setting and runs through crossbeam, linear bearing be sheathed on the axis of guide outer and both be slidingly connected, linear bearing is arranged in the crossbeam and with crossbeam fixedlys connected, fixedly connected with train line frame wallboard in the two ends of the axis of guide, the two ends of crossbeam link to each other with the crossbeam driving mechanism, crossbeam slides up and down at the effect lower edge of the crossbeam driving mechanism axis of guide, is equipped with many longitudinal knife side by side in the bottom of crossbeam.
Described longitudinal knife is made up of cutter hub and blade, and blade is removably mounted on the cutter hub.Longitudinal knife makes split-type structural, is convenient to the maintenance and the replacing of blade.
As preferably, blade is to be fixed on the cutter hub by screw.Have the advantage of convenient disassembly is installed firmly.
The edge of a knife of longitudinal knife and the angle of horizontal plane are important design parameters, can increase sharpness when cutting book for making, reduce stressedly, and as preferably, the edge of a knife of described blade and the angle of horizontal plane are 15 °～40 °.
As preferably, the angle of the described edge of a knife and horizontal plane is 35 °.Be the angle that adopts about 20 degree in the prior art, and the utility model make and has further reduced impact by rip cutting process proper extension through repeatedly drawing employing 35 degree angles after the practice, facts have proved that effect is fine, is better than the setting of other angle.
As preferably, bottom at crossbeam is provided with groove, in groove, be fixed with and insert, in described inserting, tiltedly be provided with a T type guide groove, in T type guide groove, be provided with T type slide block along the crossbeam length direction, T type slide block and T type guide groove are slidingly connected, T type slide block bottom is provided with internal thread hole, tiltedly is provided with through hole at cutter hub, and screw is tightened after passing the internal thread hole of through hole and T type slide block, T type slide block is pressed on the step surface of T type guide groove, thereby cutter hub is fixed on the crossbeam.Longitudinal knife of the present utility model is easier for installation, owing to adopted rational constraint, only need tighten screw and just a longitudinal knife can be fixed, and unclamp this screw, and the longitudinal knife cutter hub can slide along T type guide groove again, moves on any one position.
As preferably, on cutter hub, be provided with through hole, one knife bar passes the through hole of each cutter hub successively, one end of knife bar is provided with anchor ear, the other end is provided with internal thread hole, be provided with adjustment screw in internal thread hole, be arranged with the adjustment piece on the knife bar between the two adjacent cutter hubs, the two ends of described adjustment piece offset with adjacent two cutter hubs respectively.When needs change the specification of book, need to change the spacing between two cuttves of longitudinal knife, at this moment, only need to change the adjustment piece between the two adjacent longitudinal knives, select the adjustment piece of different length according to books size needs, mobile again anchor ear is tightened to the longitudinal knife outside again after the replacing, will be enclosed within the several adjustment pieces on the knife bar and several longitudinal knife is fixedly clamped.
As preferably, described crossbeam driving mechanism comprises crank a, connecting rod a, crank b, axle, crank c and connecting rod b, wherein, the end of crank a connects power source, the end of the other end and connecting rod a is hinged, and the other end of connecting rod a and crank b are hinged, links to each other by axle between crank b and the crank c, crank b is connected with axle key, be provided with hold-fast body on crank c, crank c links to each other by hold-fast body with axle, crank c and connecting rod b are hinged, and the end of connecting rod b and crossbeam is hinged.Existing main shaft drives mechanism adopts the eccentric shaft drives structure, eccentric shaft rotates outputting power drive main shaft and moves up and down, the shortcoming of this structure is that eccentric shaft is because self rigidity deficiency, on the bigger basis of exerting oneself, be easy to generate flexural deformation, and longitudinal knife is offset, cutting the book section has burr, bright and clean inadequately, influences the cutting knife effect.Crossbeam driving mechanism of the present utility model adopts brace and connecting rod framework, and it is bigger to exert oneself, and each member stress is reasonable, and the section of the book of cutting is bright and clean, no burr.
