Abstract
The utility model discloses an independent driving device for the printing roller of a flexographic press, which comprises a second driven gear fixed on the printing roller, a first driven gear rotatably arranged on an embossing roller or a screen roller, and a driving gear engaged with the first driven gear and driven by a power device, wherein the first driven gear is engaged with the second driven gear. The independent driving device for the printing roller of the flexographic press has a simple structure, solves the problem that two many mechanical vibrations exist in independent power in the prior art, and improves the reliability of operation.
Description
Technical field
The utility model relates to the flexible printing machine technical field, is specifically related to a kind of version roll driving apparatus of flexible printing machine.
Background technology
As shown in Figure 1, flexible printing machine comprises tangent successively net roller 2, version roller 3 and roller platen 1, printing ink is transferred to the printing elements that is fixed on edition roller 3 through net roller 2, and the squeegee pressure between version roller 3 and roller platen 1 is transferred to the printing ink on the forme above the printable fabric then.Gear-driven traditional flexible printing machine, as shown in Figure 2, roller platen 1 directly is connected with power set, fixedly connected driving gear 5 on roller platen 1, the driven gear 6 of version fixedly connected and driving gear 5 engagements on the roller 3, thus the power resources of version roller 3 and roller platen 1 in same power, the printing girth of this tradition flexible printing machine is subjected to the restriction of gear, can only the printing plate cylinder gear printing length of the integral multiple of driven gear 6 pitches just, and can not realize printing arbitrarily the requirement of girth.At present, the settling mode that can realize printing arbitrarily girth is to adopt independent power directly to drive the version roller 3 (as shown in Figure 3) of gearless, but owing to version roller 3 diameters produce size variation (as the size variation of version roller 3 among Fig. 1) along with the needs of printing girth, the shaft core position of different-diameter version roller moves along the perpendicular bisector of roller platen 1 with net roller 2 both lines of centres.When changing different-diameter version roller, need realize that it fixes by slide block device 4, because version roller 3 connects as one with motor 7, motor 7 positions change along with the change of version roll shaft heart position, the complex structure that causes slide block device, make difficult cost height, and movably motor brings more mechanical oscillation, causes printing trouble.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of flexible printing machine version roller drive device simple in structure is provided, overcomes the problem that there are more mechanical oscillation in independent power in the prior art, improve the reliability of work.
For solving the problems of the technologies described above, the technical solution of the utility model is: flexible printing machine version roller drive device comprises second driven gear that is fixed on edition roller; First driven gear on roller platen or the net roller is located in rotation, described first driven gear and the engagement of described second driven gear; Driving gear with described first driven gear engagement by the power set driving.
As a kind of optimized technical scheme, described first driven gear rotates and is located on the described roller platen.
As another kind of optimized technical scheme, described first driven gear rotates and is located on the described net roller.
After having adopted technique scheme, the beneficial effects of the utility model are: the utility model keeps being used for fixing in the prior art slide block device inconvenience of edition roller, change the connected mode of higher level's driven wheel of traditional flexible printing machine version roller, be rotatably assorted by fixedly connected becoming, middle idle wheel as the driving of version roller, drive by the independent power that fixedly installs then, realize the purpose of flexible printing machine version roller drive.The utility model is simple in structure, low cost of manufacture; Independent power is fixed, has eliminated mechanical oscillation, the functional reliability height.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the fundamental diagram of flexible printing machine.
Fig. 2 is traditional flexible printing machine gear transmission structure schematic diagram of the prior art;
Fig. 3 is an independent power-actuated roller structure schematic diagram of the prior art.
Fig. 4 is the structure principle chart of the utility model embodiment one;
Fig. 5 is the structure principle chart of the utility model embodiment two.
Among the figure: 1. roller platen, 2. net roller, 3. edition roller, 4. carriage, 5. driving gear, 6. second driven gear, 7. motor, 8. first driven gear, 9. driving gear, 10. power set.
The specific embodiment
Embodiment one
As shown in Figure 4, a kind of flexible printing machine version roller drive device, it comprises second driven gear 6 that is fixed on edition roller 3; First driven gear 8 on the roller platen 1 is located in rotation, this first driven gear 8 and 6 engagements of second driven gear; Also comprise driving gear 9 by power set 10 drivings with 8 engagements of first driven gear.Wherein, power set 10 are fixed on the press rack, and it can adopt servomotor, also can adopt other known power set to realize.
Operation principle: adopt independent power set 10 to drive driving gears 9,, be delivered to second driven gear 6 on edition roller 3 and drive version rollers 3 and rotate, thereby realize the drive of version roller 3 through first driven gear 8 that rotates around roller platen 1 axle center.Simultaneously, roller platen 1 also drives by another power set (not shown), keeps the linear velocity unanimity of two rollers.
As shown in Figure 1, when needs change printing length, select the version roller 3 of respective diameters, by slide block device 4 of the prior art this edition roller 3 is installed and fixed and get final product, then by the drive of the realization of the drive device in the present embodiment version roller 3.Therefore, the novel requirement that can realize any printing length of this use, and the power set 10 that drive version roller 3 are fixed, have eliminated mechanical oscillation, the functional reliability height.
Embodiment two
As shown in Figure 5, the difference of present embodiment and embodiment one is that first driven gear 8 rotates and is located on the net roller 2, the independent power device 10 that is fixed on the press rack drives driving gear 9, through first driven gear 8 that rotates around net roller 2 axle center, second driven gear 6 that is delivered on edition roller 3 drives 3 rotations of version roller, thereby realizes the drive of version roller 3.Can realize the requirement of any printing length equally, and the power set that drive version roller 3 are fixed, have eliminated mechanical oscillation, the functional reliability height.
