Abstract
The utility model belongs to the technical field of printing, and particularly relates to a printer structure for avoiding printing waste. The utility model separately and independently drives the power of the printing roller and the printing roller, the printing roller is driven by an independent servo motor, the machine is started after each stop, the printing roller and the ink roller can be driven by the precision of the operation of the servo motor according to actual conditions, the whole circle of the printing roller and the ink roller is rotated oppositely before the whole operation of the equipment, after the ink on the printing plate is well moistened, the printing roller and the printing roller are pressed, and the printing roller and the base material synchronously run along with the whole printer. Since the printing position does not change, the color register between the printing units is not affected. The plate roller which is well moistened with the ink is a qualified product with good printing effect once the printing is started, and the product qualification rate is greatly improved.
Description
Technical Field
The utility model relates to a printer structure for avoiding printing waste, and belongs to the technical field of printing.
Background
The printing plate roller and the printing roller of the conventional printing mode printing unit are linked, and generally adopt gear transmission. When the printing substrate is replaced or maintained at each stop, the printing substrate and the printing substrate are separated from each other by a certain gap, but the printing substrate and the printing substrate are always kept to run or still at the same time due to linkage.
The printing roller and the base material synchronously run, and as a certain time interval is reserved between the printing roller and the base material, the printing plate is dried during restarting, so that the base material at the head section is not printed or printed cleanly, and the printing on the printing plate can be recovered to print normally after being well wetted by the ink roller, but in the process, the printing roller can also rotate, so that the printing position is changed, namely, printing is started in the ink wetting process, the printing quality at the head section of a product is reduced, the quality of the product is unqualified, and the base material is wasted.
In order to solve the problems, customers require a reversing function (reversing and reprinting), so that the equipment is required to lengthen the occupied space, the production cost is increased greatly, reprinting can also cause double image printing of the section because deviation correction and tension errors cannot be completely overlapped, and the problem that the product is unqualified cannot be solved.
Disclosure of Invention
According to the defects in the prior art, the technical problems to be solved by the utility model are as follows: the printer structure capable of avoiding printing waste is provided, and the product qualification rate is improved.
The utility model relates to a printer structure for avoiding printing waste, which comprises a plurality of groups of printing units, wherein the printing units comprise printing plate rollers and printing receiving rollers which can be pressed and separated under the action of a driving device, and the printing plate rollers and the printing receiving rollers are driven by a servo motor respectively.
The printing plate roller and the printing roller are respectively arranged on the frame I and the frame II through bearings, and are connected with respective servo motors through respective couplings.
Preferably, the driving device is a ball screw driven by an air cylinder or a motor.
The surface of the printing plate roller is provided with a printing plate.
The printing mode of the utility model separately and independently drives the power of the printing receiving roller and the power of the printing plate roller, and the power of the printing receiving roller and the power of the printing plate roller are not linked. The printing plate roller is driven by an independent servo motor, and is started after each stop, the printing plate roller and the ink roller can be driven to rotate by an integral circle according to the actual condition through the precision of the operation of the servo motor before the whole operation of the equipment, after the ink on the printing plate is well moistened, the printing plate roller and the printing receiving roller are pressed, and the printing plate roller and the printing receiving roller synchronously operate along with the whole printing machine and the base material.
Compared with the prior art, the utility model has the following beneficial effects:
according to the printer structure for avoiding printing waste, the printing roller is driven by the servo motor to rotate for integer circles before operation, and the printing position is not changed, so that the color register among printing units is not affected. The plate roller which is well moistened with the ink is a qualified product with good printing effect once the printing is started, the waste of a base material caused by poor printing effect due to the drying of the ink after the shutdown is avoided, and the product qualification rate is greatly improved.

Fig. 1 is a schematic structural view of the present utility model.
In the figure: 1. a printing unit; 2. a plate roller; 3. a print receiving roller; 4. printing plate; 5. a bearing; 6. a coupling; 7. a servo motor; 8. an ink roller; 9. a frame I; 10. and a frame II.
Detailed Description
The utility model will be further illustrated with reference to specific examples.
However, the description of the present utility model is merely an embodiment of a structural or even functional description, and the scope of the claims of the present utility model is not limited by the embodiments described herein.
For example, the embodiments may have various modifications and various forms, and it is to be understood that the scope of the claims of the present utility model includes equivalents capable of realizing the technical idea.
As shown in fig. 1, the present embodiment is implemented by the following technical scheme: the printing unit 1 comprises a printing plate roller 2 and a printing roller 3 which can be pressed and separated under the action of a cylinder or a motor-driven ball screw, a printing plate 4 is arranged on the surface of the printing plate roller 2, and the printing plate roller 2 and the printing roller 3 are driven by a servo motor 7.
In this embodiment, both ends of the plate roller 2 and the printing roller 3 are respectively disposed on a frame I9 and a frame II10 through bearings 5, and the plate roller 2 and the printing roller 3 are connected to respective servo motors 7 through respective couplings 6.
In this embodiment, the power of the printing roller 3 and the power of the printing plate roller 2 are separately and independently driven, and the two are not linked. The printing plate roller 2 is driven by an independent servo motor, and is started after each stop, the printing plate roller 2 and the ink roller 8 can be driven by the precision of the operation of the servo motor according to actual conditions, and are counter-rotated for an integer circle before the whole operation of the device, after the ink on the printing plate is well moistened, the printing plate roller 2 and the printing receiving roller 3 are pressed together, and synchronously operate along with the whole printer and the substrate. The printing roller is driven by the servo motor to rotate for integer circles before operation, and the printing position is not changed, so that the color register among all printing units is not affected. The plate roller which is well moistened with the ink is a qualified product with good printing effect once the printing is started, the waste of a base material caused by poor printing effect due to the drying of the ink after the shutdown is avoided, and the product qualification rate is greatly improved.
Of course, the foregoing is merely preferred embodiments of the present utility model and is not to be construed as limiting the scope of the embodiments of the present utility model. The present utility model is not limited to the above examples, and those skilled in the art will appreciate that the present utility model is capable of equally varying and improving within the spirit and scope of the present utility model.
