Abstract
The utility model discloses a horizontal shifting device of a scraper of a printing machine, which is connected with the scraper of the printing machine and comprises a motor, an eccentric wheel and a connecting rod which are sequentially connected, wherein the connecting rod is connected with the scraper, and the eccentric wheel drives the scraper to horizontally and repeatedly shift through the connecting rod. According to the utility model, the independent driving of the transverse movement is provided for the scraper, so that the left-right movement of the scraper changes the track of the ink scraper on the plate roller, the friction between the edge of the scraper and the plate roller is reduced, the service lives of the scraper and the plate roller are prolonged, impurities on the scraper can be brought down, the cutter line and the flying ink are reduced, the ink scraping effect is better, and the printing quality is effectively improved.
Description
Technical Field
The utility model belongs to the technical field of printing machinery, and relates to a transverse shifting device of a scraper of a printing machine.
Background
The performance requirements of an ink blade of an intaglio printing blade as one of the important component parts of the printer are very good. Only the ink scraper with high quality has a certain improvement on the production speed and efficiency of printing, and the scraper has a very important influence on the quality of printing products.
When the printing roller of the printing machine rotates, the printing roller brings ink under the scraper, the ink has a force to the scraper, so that the ink scraper has a trend of outwards overturning, the trend is overcome through the air cylinder, the printing roller has a pressure, the ink outside the screen pit of the printing roller is forced to be scraped, in the practical application process, the ink scraper is extremely easy to produce scratches, the scraper and the printing roller can be worn, and the printing quality is seriously influenced.
Disclosure of Invention
The utility model aims to provide a transverse shifting device of a scraper of a printing machine, which reduces the friction between the cutting edge of a doctor blade and a plate roller by changing the track of an ink scraper on the plate roller.
The technical scheme includes that the transverse shifting device of the scraper of the printing machine is connected with the scraper of the printing machine and comprises a motor, an eccentric wheel and a connecting rod which are sequentially connected, wherein the connecting rod is connected with the scraper, and the eccentric wheel drives the scraper to transversely and repeatedly shift through the connecting rod.
The present utility model is also characterized in that,
the motor is a variable frequency motor.
The motor is fixed on the motor fixing base.
One end of the connecting rod is fixed with a joint bearing, and the joint bearing is positioned on the eccentric wheel.
The offset distance generated by the eccentric wheel is more than 0mm and less than 5mm.
The other end of the connecting rod is fixed with a rod end spherical bearing, an outer wire at the ball end of the rod end spherical bearing is fixed on a connecting plate through a nut, and the connecting plate is fixed on the scraper.
The connecting plate is fixed on the scraper through bolts.
The beneficial effects of the utility model are as follows:
the horizontal shifting device of the scraper of the printing machine is suitable for the scraper device of the unit type gravure printing equipment, and has the advantages of simple and compact structure and high modularization degree; the cost is low and the manufacturability is strong; through providing the independent drive of horizontal drunkenness to the scraper, the track of drunkenness change printing ink scraper on the version roller about making the scraper, lighten the friction of doctor blade and version roller, extension doctor blade and version roller's life can take the impurity on the scraper off moreover, reduces knife line, flying ink, makes the scraping ink effect better, has effectively improved print quality.
Drawings
Fig. 1 is a schematic view of a structure of a lateral shifting device of a doctor blade of a printing machine according to the present utility model.
In the figure, 01, a variable frequency motor, 02, an eccentric wheel, 03, a joint bearing, 04, a connecting rod, 05, a rod end spherical bearing, 06, a motor fixing base, 07, a connecting plate, 08, a scraper and 09, and a connecting plate.
Detailed Description
The utility model will be described in detail below with reference to the drawings and the detailed description.
The utility model 1. A horizontal shifting device of a scraper of a printing machine is connected with a scraper 08 of the printing machine, and as shown in figure 1, the horizontal shifting device comprises a motor 01, an eccentric wheel 02 and a connecting rod 04 which are sequentially connected, wherein the connecting rod 04 is connected with the scraper 08, the motor 01 drives the eccentric wheel 02 to rotate, and the eccentric wheel 02 drives the scraper 08 to horizontally and repeatedly shift through the connecting rod 04.
The motor is fixed on motor unable adjustment base 06, and motor 01 is inverter motor, through adjusting inverter motor rotational speed in order to adjust the frequency of scraper 08 drunkenness.
One end of the connecting rod 04 is fixed with a knuckle bearing 03, the knuckle bearing 03 is positioned on the eccentric wheel 02, the knuckle bearing 03 plays a role in connecting the connecting rod 04 and the eccentric wheel 02, and the offset distance generated by the eccentric wheel 02 is more than 0mm and less than 5mm.
The other end of the connecting rod 04 is fixed with a rod end spherical bearing 05, an outer wire at the bearing ball end of the rod end spherical bearing 05 is fixed on a connecting plate 07 through a nut, and the connecting plate 07 is fixed on a scraper 08 through a bolt.
The working process of the transverse shifting device of the scraper of the printing machine is as follows:
the motor 01 is adjusted to reach the required rotating speed, the motor 01 drives the eccentric wheel 02 to rotate, and due to the special eccentric structure of the eccentric wheel 02, the eccentric wheel generates a certain offset, so that the eccentric wheel 02 drives the scraper 08 to transversely and repeatedly move through the connecting rod 04. The transverse repeated movement of the scraper reduces the friction between the cutting edge of the scraper 08 and the plate roller, reduces the abrasion of the scraper and the plate roller, and improves the ink scraping effect.
According to the utility model, the transverse shifting device of the scraper of the printing machine is independent of the printing machine, has high design standardization and modularization degree, is simple to install, connect and debug, effectively prolongs the service life of the printing machine, and improves the printing quality.
