Abstract

The utility model relates to a registering device of a printing machine, aimed at solving the problems caused by the unbalance of the gear transmission and improving the accuracy. Three shafts 12, 13, 14 are arranged among the wall plates of the machine base of the printing machine, and the shafts are provided with circumferential and axial plate adjusting mechanisms. A gear 5, a printed gear 7 and a roll gear 9 all use cylindrical spiral gears, and the gear 5, the printed gear 7 and the roll gear 9 are sequentially engaged. The circumferential surfaces of the gear 5, the printed gear 7 and the roll gear 9 are provided with corresponding grooves, and the groove of the gear 7 is embedded with a guard plate 6. The utility model has the advantages of balanced transmission of the whole machine, transmission accuracy increase, production efficiency increase, noise decrease and convenient and reliable operation.

Description

Flexographic presses helical gear register sets

The utility model relates to printing machine, especially refers to flexographic presses helical gear register sets.

In background technology, since flexographic presses is come out, in order to print the polychrome product automatically, assemble some print couple, because printing process is a dynamic process, accurate in order to guarantee the multicolor patterns chromatography, so, solve the axial and circumferential displacement of printing forme roller at each group version roller place's assembling register sets.In the present this register sets, see shown in Figure 1, assembling motor 1 on the printing machine support, motor shaft connects axially displaceable slide block 2, slide block 2 one side shields contacts can axially movable pinion 3, assembling pinion 3 and gear wheel 4 engagements on the axle 12, the assembling gear wheel 4 and the roller 8 of undertaking the printing of on the axle 13, assembling forme roller 10 and axial adjustment handwheel 11 on the axle 14, on axle 12, also adorn spur gear and the engagement of the spur gear of the roll shaft 13 of undertaking the printing of, on the axle 13 spur gear again with axle 14 on spur gear engagement, transfer a version mechanism thereby form circumference.When needs circumferential displacement during to version, motor 1 rotates, and makes slide block 2 left and right displacement by the leading screw form, makes helical gear 3 axially displaced thereupon, because the helical teeth engagement, during parallel gear wheel 4 slippages of pinion 3, drives axle 12 and rotates; By the spur gear engagement, the rotation that makes printing forme roller 10 produce the circumference upper angle reach the purpose of circumference to version, but its weak point is the spur gear wheel transmission, brings transmission not steady, and noise is big, easily produces black thick stick on the print product, directly influences the quality of product.Its axial displacement is by manual fine-tuning axial adjustment handwheel 11, and printing forme roller 10 is axially transferred version mechanism along the displacement of axle 14 generations thereby form, and reaches axial purpose to version.

The purpose of this utility model is the problem that produces in the above-mentioned background technology, with spur gear on the roll shaft 13 of undertaking the printing of and the spur gear on the printing forme roll shaft 14, and the third wheel on the axle 12 all changes cylindric spiral gear into, solution does not steadily influence the problem of product quality because of transmission, also solved simultaneously because of assembling the axial of helical gear generation, the circumferential edition problem that interferes with each other of transferring has finally reached circumferential, axial accent version and has moved separate, complete machine stable drive, noise are little, improve the purpose of print quality

Technical solution of the present utility model is as follows:

Comprise following technology: assembled shaft 12, undertake the printing of roll shaft 13 and printing forme roll shaft 14 between printing machine support wallboard, going up the assembling circumference for three transfers version mechanism and axially transfers version mechanism, it is characterized in that: the gear 5 excessively on the axle 12, the plate roller gear 9 of undertaking the printing of on undertake the printing of gear 7 and the printing forme roll shaft 14 on the roller 13 is cylindric spiral gear, and engagement successively, on three

gears

5,7 and 9 circumferential surfaces corresponding groove is arranged, in gear 7 circumferential grooves of undertaking the printing of, inlay and to make the three gears catch 6 of synchronous shift vertically.

Accompanying drawing Fig. 1 of the present utility model is the overall work schematic diagram, and number in the figure is described as follows:

1-motor 2-slide block 3-bevel pinion 4-large helical gear 5-crosses gear

The 6-catch 7-helical gear 8-roller 9-plate roller helical gear 10-printing forme roller of undertaking the printing of of undertaking the printing of

The 11-axial adjustment handwheel 12-axle 13-roll shaft 14-printing forme roll shaft of undertaking the printing of

-ball bearing-sliding bearing

Following adjoint is described in further detail: referring to Fig. 1, at flexographic presses support both sides wallboard one side assembling motor 1 and leading screw slide block 2, assembling is three between the wallboard, promptly the axle 12, undertake the printing of roll shaft 13 and printing forme roll shaft 14, assembling pinion 3 and cross gear 5, the assembling gear wheel 4 and the roller 8 of undertaking the printing of on the axle 13 on the axle 12, buck plate roller gear 9 and printing forme roller 10 and axial adjustment handwheel 11 on the printing forme axle 14, roller 10 and helical gear 7 all assemble sliding bearing and rolling bearing here.Can move axially.Cross gear 5 also with rolling bearing and feather key assembling, equally can be axially displaced.Operation principle is like this, when needs are done circumference to version, baffle plate forces pinion 3 left and right displacement thereupon below motor 1 rotating band movable slider 2 left and right displacement, slide block 2, because gear wheel 4 is helical gears, suppose that 4 is motionless, then during pinion 3 move left and right, will rotate, thereby the gear 5 of crossing that drives on coaxial 12 also rotates, undertake the printing of gear 7 and the plate roller gear 9 of engagement will also be rotated, reach the purpose of printing forme roller 10 circumference version.When carrying out axially to version, artificial turning cylinder is to adjusting handle 11, then plate roller gear 9 and printing forme roller 10 produce synchronous axial displacement, because the utility model adopts helical gear, as not doing specially treated, to occur undertaking the printing of roller 8 and cross gear 5 and rotate an angle destroys original existing circumference to the version effect.In order to solve this difficult problem, the correspondence position that meshes at

gear

5,7,9 has Baltimore groove.Inlay catch 6 in the gear 7 performance grooves of undertaking the printing of, when gear 9 axial displacements, gear 7 and 5 synchronous axial displacements do not produce circumference and rotate like this.

Advantage of the present utility model and effect are as follows:

1, owing to adopt slant gear transmission, shakes so solved the transmission that original cylindrical straight gear transmission brings Moving big, noise is big, and to problems such as version inaccuracy, it is little to have reached transmission balance noise, and is more accurate to version, more Reliable purpose.

2, because employing circumference of gear groove studs with catch, thus make the axial displacement of the gear synchronous that is meshed, Solved because of adopt that helical gear brings axially and circumference to the problem that version interferes with each other, reached axially to version The purpose of version independently being carried out separately with circumference.

3, because complete machine adopts the helical gear transmission, thus not only transmission balance of complete machine, and also easy to operate, improved positioning accuracy, improved print quality, reduce the printing percent defective and reduced production cost.
