Description
Technical Field
The utility model relates to an ink fountain structure of a printing machine.
Background
The ink fountain structure used in the current printing press comprises an ink key motor 11 and an ink key 12 mounted on an ink key base 10, and an ink fountain roller 20 (see fig. 1 a) which is in butt joint with the ink key 122, and the working process is as follows: the ink fountain roller 20 rotates counterclockwise, and the ink 30 is transferred away by friction with the ink 30 in the ink fountain 1. The ink key motor 11 moves the ink keys 12 back and forth, changing the gap between the ink keys 12 and the ink fountain roller 20, thereby changing the amount of ink transferred by the ink fountain roller 20. However, when the ink used is large in viscosity (caused by low air temperature, or the characteristics of the ink itself such as UV ink), the following problems occur: the ink fountain roller 20 transfers a part of ink, and the ink 30 at the rear part of the ink fountain 1 cannot be timely leaned against the ink fountain roller 20 by virtue of the gravity of the ink because of the high viscosity of the ink at the moment. At this time, a gap occurs between the ink 30 and the duct roller 20 (see fig. 1 b), so that the ink 30 cannot be transferred.
Currently, the solution to the above problem is to provide an ink stirring device in the ink fountain, where the ink stirring device is connected across a guide rail 30 between two wall boards and above the ink fountain, two stirring pieces 3 are mounted on the guide rail 30, and the two stirring pieces 3 are moved left and right along the guide rail 30 by using a manual or air cylinder as power to stir the ink in the ink fountain 1, so that the viscosity of the ink is reduced (see fig. 2a and 2 b). However, such ink stirring devices suffer from the following problems during use:
1. the effect of reducing the viscosity of the ink is poor, and the ink only acts on the ink around the ink stirring sheet in the ink fountain;
2. when the agitator blade moves just to an ink zone, additional pressure is applied to the ink in that zone, at which point the ink is forced out of the gap between the ink key and the fountain roller more, resulting in a different ink shade on the print.
Disclosure of Invention
The utility model aims to overcome the defects of the prior art and provide an ink duct structure of a printing machine, which more effectively solves the problem that high-viscosity ink in the ink duct is not easy to drop.
The purpose of the utility model is realized in the following way: the ink duct structure of the printer comprises an ink duct arranged between two ink duct side plates, an ink key arranged at the bottom of the ink duct, an ink key motor for driving the ink key to move forwards and backwards, and an ink duct roller arranged in front of the ink duct and butted with the front end of the ink key; the ink fountain structure also comprises an ink stirring device; wherein, the liquid crystal display device comprises a liquid crystal display device,
the ink stirring device comprises an ink stirring roller and an ink stirring roller driving mechanism; the ink stirring roller is bridged between the front parts of the two ink fountain side plates through two bearings and is immersed in the ink fountain; the ink stirring roller driving mechanism comprises a servo motor arranged on the inner side surface of one ink fountain side plate, a driving belt pulley arranged on the servo motor, a driven belt pulley arranged on one end of a mandrel of the ink stirring roller and a synchronous belt wrapped between the driving belt pulley and the driven belt pulley.
In the ink fountain structure of the printer, the surface of the ink stirring roller is provided with a spiral flange with the pitch of 10 mm.
The ink fountain structure of the printer, wherein the gap between the ink stirring roller and the ink fountain roller is 10-15 mm.
The ink fountain structure of the printer has the following characteristics: by arranging a rotary ink stirring roller at the front part of the ink fountain and arranging a spiral flange on the surface of the ink stirring roller, the ink in the ink fountain can be stirred, the viscosity of the ink can be reduced, a forward pushing force can be generated, the ink can be pushed to the ink fountain roller, the ink stirring action of the ink stirring roller is continuous to the ink pushing force in a single ink area, and the ink color depth change on a printed product in the printing process can not be caused.

Detailed Description
The utility model will be further described with reference to the accompanying drawings.
Referring to fig. 3 and 4, the ink fountain structure of the printer of the present utility model includes an ink fountain 10 installed between two ink fountain side plates 100, an ink key 13 installed at the bottom of the ink fountain 10, an ink key motor 12 driving the ink key 13 to move forward and backward, and an ink fountain roller 20 provided in front of the ink fountain 10 and abutting against the front end of the ink key 13.
The ink fountain structure also comprises an ink stirring device; the ink stirring device comprises an ink stirring roller 4 and an ink stirring roller driving mechanism; wherein, the liquid crystal display device comprises a liquid crystal display device,
the ink stirring roller 4 is bridged between the front parts of the two ink fountain side plates 100 through two bearings and is immersed in the ink 30 in the ink fountain 10, and the gap between the ink stirring roller 4 and the ink fountain roller 20 is preferably 10-15 mm; the surface of the stirring roller 4 is provided with a spiral flange with the pitch of 10 mm;
the agitator driving mechanism includes a servo motor 40 mounted on the inner side surface of one of the ink fountain side plates 100, a driving pulley 41 mounted on the servo motor 40, a driven pulley 42 mounted on one end of the spindle of the agitator 4, and a timing belt 43 wrapped between the driving pulley 41 and the driven pulley 2.
