Abstract

A box adhering machine with a rack-gear-pair precise transverse moving mechanism on a folding part comprises a first transmission pair and a second transmission pair. The first transmission pair is composed by a screw and a nut sleeve. The second transmission pair comprises a straight rack and gears meshed with the straight rack, wherein the straight rack is milled by two bottom ends of a long roller, and each gear is fixed on a gear shaft. The long roller is fixed on frame and penetrates a left crossbeam and a right crossbeam through a guide sleeve fixedly connected with the crossbeams. Each gear shaft is fixed on one side of the corresponding crossbeam, two ends of the gear shaft are connected with a connecting shaft through connecting sleeves respectively, and the connecting shaft is connected with the straight rack gear pairs which are located in the front of and at the rear crossbeam and have the same parts. Same mechanisms are mounted on the lateral sides of the left crossbeam and the right crossbeam. When the screw drives the crossbeams to move transversely, the gears on the gear shafts on one side of the crossbeams move transversely along with the crossbeams, the gears meshed with the fixed straight rack are forced to rotate so as to drive the corresponding connecting sleeves and connecting shafts to rotate at the same time, the rotation is then transmitted to the front and rear identical mechanisms, and synchronous transverse moving of the crossbeams is achieved.

Description

Folding part is provided with the case binder of the accurate transverse-moving mechanism of rack-pinion

Technical field

The present invention relates to a kind of production cardboard, post-production equipment---the corrugated board tapping machine of the package packing machine of carton, particularly relates to a kind of corrugated board tapping machine by impression folded, glued mode, and its folding part is provided with the accurate transverse-moving mechanism of rack-pinion.

Background technology

Corrugated board tapping machine is widely used a kind of package packing machine, its primary structure as shown in Figure 1, comprise paper feed unit 11, folding unit 12, coating unit 13, arrange output unit 14, each unit is unified under the effect of power-equipment and transmission mechanism to cooperate in harmony, and jointly completes the paper feeding of cardboard, folding, gluing and arrangement and exports.Folding part is wherein provided with the accurate transverse-moving mechanism of rack-pinion, and this mechanism adopts two groups of transmissions, and one group is made up of a rhizoid bar and a nut sleeve, by the rotation of screw mandrel, drives large Beam laterally to move left and right; Another group is made up of a spur rack and a gears meshing, spur rack is formed by the bottom milling of a long roller, long roller is fixed in frame, long roller is run through by the guide pin bushing be fixedly connected with large Beam and between the large Beam in left and right, gear is fixed on a gear shaft, gear shaft is fixed on the side of large Beam by the bearing block at two ends, and its two ends are connected with a connecting axle by a coupling sleeve again respectively, and connecting axle is connected with the rack-pinion having same part be loaded on before and after large Beam again by coupling sleeve; Identical mechanism is all equipped with in the side that the large Beam in left and right is corresponding, reaches the accurate traversing object of large Beam by this mechanism.Existing corrugated board tapping machine, as shown in Figure 2, it comprises the long roller 22 of kink between the large Beam in both sides, folding part 23 of case binder to the primary structure of the traversing mode of the large Beam in its folding part, and long roller is fixed in frame, and large Beam can left and right slippage on long roller; In the corner, side of large Beam, upper and lower four rolling 231 is housed, between upper bottom roller, has a guide rail 232, roller can on guide rail roll-sliding; The transmission that one group of screw mandrel 21 forms with nut sleeve 211 is respectively housed above the large Beam in left and right, and rotary screw rod, large Beam is by roller transverse shifting under the guiding of guide rail.At large Beam mono-side-lower, folding bar 233 and lower support wheel 234 on one are housed, upper folding bar targeted by the Indentation position of cardboard, and lower support wheel, by cardboard lifting, forms the folding of certain angle; Cardboard 24 completes the conveying of cardboard, folding, painting glue bond under having the extruding of the lower delivery wheel roller 242 of flat belt by the upper delivery wheel roller 241 between large Beam and cover, then enters arrangement output unit.

Along with the progress of technology, the productivity ratio of corrugated board tapping machine is more and more higher, now just develop with the speed of 60 to 250 per minute per minute, the raising of this productivity ratio, the frequency requiring paper feeding certainly will be brought to accelerate, the transmission of cardboard is more stable, impression location is more accurate, realize this goal, it is not all right that the large Beam of traditional corrugated board tapping machine drives roller to carry out traversing mode at slide on rails by screw mandrel swivel nut, due to the gap of long roller and large Beam guide pin bushing, and the gap between feed screw nut's cover, add before and after large Beam and have longer distance, therefore the upper folding bar 233 at front and back two place will the Indentation position of substantial deviation cardboard, cause folding cardboard crooked, have a strong impact on the quality of paperboard bonding, percent defective improves greatly, in order to improve paperboard bonding quality, reduce and consume, must the price of both expensive go to purchase high-grade corrugated board tapping machine, this adds very large burden to a large amount of medium and small Carbon enterprises, cause heavy losses, go down for a long time and certainly will affect the production of carton.Thus a kind of raising that can meet speed of production on the corrugated board tapping machine of traditional traversing large Beam of mode of being overlapped by feed screw nut is needed, high-quality product can be bonded out again, adapt to the needs of different Carbon enterprise development, existing technical method, be the requirement that can not be applicable to market, user has strong complaints.

Summary of the invention

Object of the present invention, it is the case binder in order to provide a kind of folding part to be provided with the accurate transverse-moving mechanism of rack-pinion, to ensure to seek to overcome because speed of production is fast on the corrugated board tapping machine of traditional traversing large Beam of mode of being overlapped by feed screw nut, cause impression to locate the indefinite phenomenon of incorrect, folding size variation and affect the solution of carton quality, to ensure to accomplish that speed of production is fast, bonding quality is good, improves to maximum work quality and precision.
