Abstract
The utility model discloses a printing roller device suitable for local printing, including frame and support, the support is fixed in the frame, swing joint has the printing roller on the support, a printing roller pot head is equipped with first gear, characterized by still be equipped with in the frame and be independent of the driven servo motor of compression roller, the printing roller is connected with the servo motor transmission. The utility model discloses china and india's brush roll is driven by solitary servo motor, when normal printed patterns, through servo motor adjustment printing roller rotational speed, it can to make that its rotational speed is the same with the compression roller rotational speed, when two printed patterns's interval is adjusted to needs, driving servo motor with higher speed or slow down and rotate when the printing plate of printing on the roller leaves the compression roller, thereby make the printing roller accelerate the rotation or slow down to rotate, reach the mesh of two printed patterns's of regulation interval, it is very convenient to adjust, and need not change printing roller and gear, make work efficiency improve greatly.
Description
Technical field
The utility model relates to a kind of print roller device being applicable to local printing.
Background technology
At present, the device of local printing generally includes pressure roller, print roller and drop roller, one end of pressure roller, print roller and drop roller is all arranged with intermeshing gear, the gear of pressure roller is driven by motor, pressure roller, print roller and drop roller interlock during work, said structure can only change the print roller of different-diameter when printed patterns spacing is different, and the diameter change of print roller, gear in print roller also must be changed, could with the gears meshing of transmission mechanism, Renewal process is loaded down with trivial details, loses time, and operating efficiency is reduced greatly.
Summary of the invention
In view of the deficiency of background technology, technical problem to be solved in the utility model is to provide a kind of print roller device being applicable to local printing of adjustable printed patterns spacing.
For this reason, the utility model adopts following scheme to realize:
Be applicable to the print roller device of local printing, comprise frame and bearing, described bearing is fixed in frame, described bearing is connected with print roller, described print roller one end is arranged with the first gear, it is characterized in that the servomotor described frame is also provided with independent of pressure roller transmission, described print roller is connected with servo motor transmission.
Be provided with power transmission shaft between described servomotor and the first gear, described power transmission shaft one end is arranged with the second gear with the first gears meshing, and the power transmission shaft other end is arranged with the 3rd gear, the motor shaft of servomotor is arranged with the 4th gear with the 3rd gears meshing.
The advantage of the utility model contrast prior art is: print roller is by independent driven by servomotor, when normal printed patterns, by servomotor adjustment print roller rotating speed, make its rotating speed identical with pressure roller rotating speed, when needing the spacing of adjustment two printed patterns, drive servomotor acceleration or deceleration to rotate when the forme in print roller leaves pressure roller, thus make print roller accelerate to rotate or underdrive, reach the object of the spacing of adjustment two printed patterns, regulate very convenient, and print roller and gear need not be changed, operating efficiency is improved greatly.
Accompanying drawing explanation
The utility model has following accompanying drawing:
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, the print roller device of local printing that what the utility model provided be applicable to, comprise frame 9 and bearing 1, bearing 1 is fixed in frame 9, bearing 1 is connected with print roller 3, print roller 3 one end is arranged with the first gear 4, frame 9 is also provided with the servomotor 2 of separate connection print roller 3, print roller 3 and servomotor 2 are in transmission connection, power transmission shaft 5 is provided with between servomotor 2 and the first gear 4, power transmission shaft 5 one end is arranged with the second gear 6 engaged with the first gear 4, power transmission shaft 5 other end is arranged with the 3rd gear 7, the motor shaft of servomotor 2 is arranged with the 4th gear 8 engaged with the 3rd gear 7.
Utility model works principle is as follows: during normal printed patterns, servomotor 2 is driven to drive the 4th gear 8 to rotate, 4th gear 8 drives the 3rd gear 7, power transmission shaft 5 and the second gear 6 to rotate, second gear 6 drives the first gear 4 and print roller 3 to rotate, and makes print roller 3 rotating speed identical with pressure roller rotating speed; When needing the spacing of adjustment two printed patterns, drive when the forme in print roller 3 leaves pressure roller servomotor 2 acceleration or deceleration to rotate, thus make print roller 3 accelerate to rotate or underdrive, reach the object of the spacing of adjustment two printed patterns.This technical scheme is only just practical when printing plate cylinder carries out local printing, and it regulates during the spacing of printed patterns does not need to change print roller, so very practical and convenient.And when will change print roller, also do not need to change the travelling gear matched.Should use simpler.
Claims (2)
1. be applicable to the print roller device of local printing, comprise frame and bearing, described bearing is fixed in frame, described bearing is connected with print roller, described print roller one end is arranged with the first gear, it is characterized in that the servomotor described frame had independent of pressure roller transmission, described print roller is connected with servo motor transmission.
2. the print roller device being applicable to local printing according to claim 1, it is characterized in that being provided with power transmission shaft between described servomotor and the first gear, described power transmission shaft one end is arranged with the second gear with the first gears meshing, the power transmission shaft other end is arranged with the 3rd gear, the motor shaft of servomotor is arranged with the 4th gear with the 3rd gears meshing.
