Abstract
The utility model discloses a direct drive mechanism of a printing unit. The direct drive mechanism of the printing unit comprises a drive motor, an impression cylinder, a rubber blanket cylinder and a plate cylinder, wherein the drive motor is connected with the impression cylinder through a first transmission mechanism to drive the impression cylinder, and the impression cylinder, the rubber blanket cylinder and the plate cylinder are driven by gears. According to the direct drive mechanism of the printing unit, an independent motor is used for driving cylinders of various printing elements, a transmission face box structure is simplified, the difficulty for designing, processing and assembling is lowered, and printing precision is guaranteed. Meanwhile, a servo motor is used for driving, and the circumferential direction overprinting adjustment of the printing unit is achieved.
Description
Technical field
The utility model relates to the printing mechanism field, relates in particular to a kind of printing unit and directly drives mechanism.
Background technology
The type of drive of traditional printing unit is: adopt the method for printing element in all printing units of a motor-driven, between each printing element by gear drive.Use the printing set structure of this driving method very complicated.Simultaneously, this structure has very high requirement to precision, the assembly technology of transmission device, need have power transmission shaft not of uniform size, transmission layer by layer this take turns, high accuracy mechanical processing parts, strict assembly technology, could guarantee its total quality.And a motor drives a printing unit, and mechanical mechanism is very complicated, and the noise that sends during the machine operation is big.
Summary of the invention
The purpose of this utility model is to provide a kind of printing unit of simplifying driving-chain, reduction processing and installation difficulty directly to drive mechanism.
1. to achieve these goals, the printing unit that the utility model provides directly drives mechanism, comprise: drive motors, impression cylinder, blanket cylinder and plate cylinder, drive motors links to each other with impression cylinder by first transmission mechanism, drive impression cylinder, impression cylinder, blanket cylinder and plate cylinder are by gear drive.
In some embodiments, impression cylinder, blanket cylinder and plate cylinder distribute in the printing unit from the bottom to top, and be tangent between two adjacent cylinders.
In some embodiments, drive motors is servomotor.
Printing unit of the present utility model directly drives mechanism, and is simple and compact for structure, rationally distributed.Assembling and setting is easy, functional reliability good.Adopt printing element of a motor-driven, make it have very high complete machine operability, be independent of each other, improved operating efficiency.Reduce transmission simultaneously, improved the printing precision of printing unit.Adopt driven by servomotor, realized the circumferential chromatography adjustment of printing unit.
Description of drawings
Fig. 1 directly drives the structural principle schematic diagram of mechanism for the printing unit of a kind of embodiment of the utility model.
The specific embodiment
Come the utility model is described in further detail explanation below in conjunction with drawings and the specific embodiments.
Fig. 1 has shown that schematically the printing unit according to a kind of embodiment of the utility model directly drives mechanism.
As shown in the figure, the straight driving mechanism of printing unit for the printing unit of the present utility model comprises: drive motors 10 and a printing element.
In this embodiment of the present utility model, printing element is distributed with impression cylinder 1, blanket cylinder 2 and plate cylinder 3 from the bottom to top successively.Wherein, impression cylinder 1 is tangent with blanket cylinder 2, blanket cylinder 2 and plate cylinder 3, and impression cylinder 1, blanket cylinder 2 and plate cylinder 3 two ends are fixed on the frame of printing unit by roller bearings.
In sum, printing unit of the present utility model directly drives mechanism, adopts the cylinder of independent each printing element of motor-driven, has simplified the driving face body structure, has reduced the difficulty of its design, processing and assembling, has guaranteed the precision of printing.Simultaneously, adopt driven by servomotor, realized the circumferential chromatography adjustment of printing unit.
