Abstract
The invention discloses a driving device for a printing unit, which comprises a first driving motor connected with an upper water ink component in the printing unit and a second driving motor connected with a lower water ink component in the printing unit, as well as a third driving motor, wherein the output end of the third driving motor is respectively connected with four printing rollers in the printing unit through transmission gear sets which are sequentially meshed. The driving device for the printing unit has the advantages of simple and compact structure, low cost, reasonable layout, simplicity in assembly and debugging, good reliability in working and the like.
Description
Technical field
The present invention is mainly concerned with the printing equipment field, refers in particular to a kind of drive unit that prints unit.
Background technology
Traditional set type roll-fed offset printing press is formed (for example being made of four printing units) by a plurality of printing units, and the type of drive of its printing unit part has two kinds.A kind of is to adopt a motor to drive the method for a printing unit separately, and promptly four each units of printing unit are driven by a motor, so just make the printing unit need the very complicated transmission device of structure.Moreover, this structure all has very high requirement to precision, the assembly technology of transmission device, and the assembly technology that needs power transmission shaft not of uniform size, travelling gear layer by layer, high accuracy mechanical processing parts, strictness could guarantee its total quality.And a motor drives a printing unit, and frame for movement is very complicated, and the noise that sends during the machine operation is big.
Another kind is to adopt each printing cylinder that independent motor-driven method is all arranged.Whole motor layout as shown in Figure 3.Wherein, following plate cylinder 1, down blanket cylinder 2, go up blanket cylinder 3, go up plate cylinder 4 by a motor-driven independently, the end of above-mentioned cylinder directly links to each other with motor by transmission mechanism.Transfer motion power is from motor, and through reductor, by finally reaching printing cylinder behind drive sleeve, ball spline, the pin, its transmission link is more again, and structure is comparatively loaded down with trivial details.Though this method has been simplified driving-chain, reduced processing and installation difficulty, make motor realize direct head roll, but increased the connector (ball spline) and the support member (many collar bearings) of a lot of costlinesses.Not only caused the increase of cost, and be difficult to have guaranteed the installation accuracy (as: axiality) of these support members and associated components, each roller spare circumferentially beats etc. after the installation.Simultaneously, consider the actual motion characteristic of printing machine, corresponding plate cylinder and blanket cylinder will remain unchanged to the last phase position to beginning in operation process, could satisfy the typography requirement like this, but this needs high-precision electrical equipment control.
Summary of the invention
The technical problem to be solved in the present invention just is: at the technical problem that prior art exists, the invention provides a kind of simple and compact for structure, with low cost, rationally distributed, assembling and setting is easy, functional reliability is good printing unit drive unit.
For solving the problems of the technologies described above, the present invention by the following technical solutions:
A kind of printing unit drive unit, comprise first drive motors that links to each other with last ink assembly in the described printing unit and second drive motors that links to each other with following ink assembly in the described printing unit, it is characterized in that: also comprise the 3rd drive motors, the output of described the 3rd drive motors links to each other with four printing cylinders in the printing unit respectively by the driving gear set of engagement successively.
As a further improvement on the present invention:
Be furnished with blanket cylinder in the described printing unit from top to bottom successively, go up plate cylinder, following plate cylinder and following blanket cylinder.
The two ends of described printing cylinder are fixed on the frame of printing unit by roller bearings.
Compared with prior art, the invention has the advantages that:
1, the present invention prints the unit drive unit, simple and compact for structure, with low cost, rationally distributed, assembling and setting is easy, functional reliability good, it adopts meshed transmission gear, the corresponding plate cylinder of easier assurance is consistent to the last phase position to beginning with blanket cylinder, reduces the control difficulty of electric control system;
2, after the present invention uses, each printing unit quadruplet ball spline capable of reducing using, the many collar bearings of quadruplet and two servomotors and respective drive system;
3, after the present invention used, the printing machine driving face was made a whole set of grease-box, and the printing machine complete machine structure is optimized more with rationally, and is quite favourable concerning designer and user.Simultaneously, upper and lower ink assembly is driven by individual motor respectively, makes it have very high complete machine operating flexibility, for example: ink wash, change forme and blanket etc., can operate high efficiency separately in situation about not influencing mutually.Adopt this design can save the indispensable edition mechanism of circumferentially drawing in the traditional printing equipment, its function can realize circumferential chromatography adjustment by corresponding servomotor.

The specific embodiment
Below with reference to Figure of description and specific embodiment the present invention is described in further details.
As depicted in figs. 1 and 2, the present invention prints the unit drive unit, comprise first drive motors 5 that links to each other with last ink assembly 7 in the printing unit and second drive motors 6 that links to each other with following ink assembly 8 in the printing unit, first drive motors 5 is used for driving separately upward, and ink assembly 7, the second drive motors 6 are used for driving separately ink assembly 8 down.The present invention also comprises the 3rd drive motors 9, the output of the 3rd drive motors 9 links to each other with four printing cylinders in the printing unit respectively by the driving gear set 11 of engagement successively, the power of such the 3rd drive motors 9 outputs can pass to every printing cylinder successively through driving gear set 11.The 3rd drive motors 9 can be installed in the end of cylinder according to actual needs, perhaps a side of end.In actual use, can in four printing cylinders, select one as the benchmark cylinder, with synchronism and the stationarity that guarantees four printing cylinders.For example, can select down blanket cylinder 2 as the benchmark cylinder.
As from the foregoing, printing unit drive unit has kept simplifying the advantage of traditional shaftless printing press driving-chain structure among the present invention, and this technical scheme has been simplified the driving face body structure, only adopts common gear drive group, reduces design, processing and assembly difficulty significantly.The present invention further can form the whole transmission lubrication of single printing unit, reduces printing unit manufacturing cost, and the control of order printing unit is simplified.
In the present embodiment, last two printing cylinders are last forme blanket cylinder 4 and the last blanket cylinder of from top to bottom arranging 3 in the printing unit, and following two printing cylinders are following blanket cylinder 2 and the following plate cylinder of from top to bottom arranging 1 in the printing unit.The two ends of printing cylinder are fixed on the frame 14 of printing unit by roller bearings 13.Above-mentioned each motor all can adopt servomotor.
Below only be preferred implementation of the present invention, protection scope of the present invention also not only is confined to the foregoing description, and all technical schemes that belongs under the thinking of the present invention all belong to protection scope of the present invention.Should be pointed out that for those skilled in the art the some improvements and modifications not breaking away under the principle of the invention prerequisite should be considered as protection scope of the present invention.
