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 rubber and roll 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 drive unit that is used to print unit.
For solving the problems of the technologies described above, the present invention by the following technical solutions:
A kind of drive unit that is used to print 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: comprise that also the 3rd drive motors and 4 wheel driven move motor, the output of described the 3rd drive motors links to each other with last two printing cylinders in the printing unit by first driving gear set, and the output of the moving motor of described 4 wheel driven links to each other with following two printing cylinders in the printing unit by second driving gear set.
As a further improvement on the present invention:
Last two printing cylinders are last plate cylinder and the last blanket cylinder of from top to bottom arranging in the described printing unit, and following two printing cylinders are following blanket cylinder and the following plate cylinder of from top to bottom arranging in the described printing unit.
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 is used to print the drive unit of unit, simple and compact for structure, with low cost, rationally distributed, assembling and setting is easy, functional reliability good, it adopts and carries out meshed transmission gear between corresponding forme and the blanket cylinder, 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 is used to print the drive unit of 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 and the moving motor 10 of 4 wheel driven, the output of the 3rd drive motors 9 links to each other with last two printing cylinders in the printing unit by first driving gear set 11, and promptly the 3rd drive motors 9 rotates by last two printing cylinders in the driving of the gears engaged in the first driving gear set 11 printing unit.Following two printing cylinders linked to each other during the output of the moving motor 10 of 4 wheel driven passed through second driving gear set 12 and prints unit, and promptly the moving motor 10 of 4 wheel driven drives by the gears engaged in second driving gear set 12 and prints following two printing cylinders rotation in the unit.The moving motor 10 of the 3rd drive motors 9 and 4 wheel driven can be installed in the end of cylinder, perhaps a side of end according to actual needs.
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.
