In order to efficiently transfer paper sheets, roller transfer techniques are currently commonly used to transfer ink onto paper sheets. The roller type transfer printing technology needs to be provided with an ink scraping unit, the ink scraping unit comprises an ink beam, an ink inlet and an overflow port are formed in the ink beam, the ink inlet is located at the low side of the ink beam, an anilox roller is tightly attached to Mo Liang to form an ink cavity, ink is continuously input into the ink cavity through the ink inlet, when the anilox roller rotates, the ink is transferred to a printing plate roller through the anilox roller, and finally specific graphic display information is formed on the surface of a paperboard by the printing plate roller. And when the ink liquid level is too high, the ink flows out through the overflow port.
The wiping unit needs to be cleaned after a period of use. The inking roller needs to be kept in contact with the ink beams in a purged state to maintain the sealing of the ink chamber, and the inking roller is rotated to perform overall purging of the peripheral surface of the inking roller. When the water level is continuously reduced in the cleaning process, the heat accumulation of the inking roller in the rotating state causes the temperature rise of the inking roller, particularly the position of the inking roller bearing, so that the risk of bearing abrasion is increased. As can be seen, there is still room for improvement in current wiping units.

The present embodiment relates to a temperature reducing structure of an inking roller for reducing the temperature of an inking roller 45 in a wiping unit for paperboard printing.
The scraping unit is mainly divided into three states during operation, wherein the first state is an ink supply and return state, ink is supplied into the ink cavity through the ink inlet 13, and flows back through the overflow port 11 when the ink level is too high, and in this state, the inking roller 45 is immersed in the ink and can be cooled through the ink. The second state is a cleaning state in which a large amount of water enters the ink chamber and flows back from the overflow port 11, and in this state, the inking roller 45 needs to rotate at a high speed, and the inking roller 45 heats up faster. The third state is a pumping state, and the pumping state mainly pumps the ink in the ink cavity to reduce ink accumulation and solidification before long-term shutdown and cleaning, or pumps the water in the ink cavity after cleaning is completed; in this state, the inking roller 45 needs to be kept rotating, but the water is in a non-flowing state, and the ability of the water to cool down the inking roller 45 is reduced. In the second state and in the third state of the wiping unit, there is a greater risk of wear on the wiping unit.
Therefore, the utility model designs a cooling structure of the inking roller. The cooling structure of concrete inking roller includes: the ink beam comprises an ink beam 1, a water inlet pipe 21 and a cooling water pipe 22, wherein the front side of the ink beam 1 is opened for installing an inking roller 45, the water inlet pipe 21 is arranged on the Mo Liang, the cooling water pipe 22 is communicated with the water inlet pipe 21, the water outlet end of the cooling water pipe 22 is positioned in front of the ink beam 1, and the water outlet end of the cooling water pipe 22 is downward.
In the cooling structure of the inking roller, the water inlet pipe 21 and the cooling water pipe 22 are configured, when the inking roller 45 and the ink beam 1 are assembled together, water flows between the inking roller 45 and the ink beam 1 through the cooling water pipe 22 after the water inlet pipe 21 is opened, and water can flow to the left and right sides along a seam between the inking roller 45 and the ink beam 1 to cool the inking roller 45, so that the risk of ink roller blockage caused by ink accumulation of the inking roller 45 is reduced. The cooling water pipe 22 of the cooling structure of the ink beam 1 is mainly designed to cool the inking roller 45 when cleaning the ink chamber so as to reduce the abrasion to the bearing, but the water inlet pipe 21 can be selectively opened in the ink supplying state or the ink returning state so as to cool the inking roller 45.

The cooling structure of the inking roller further comprises an end sealing water disc 36 and an end sealing water drain pipe, wherein the end sealing water disc 36 is fixedly connected with the ink beam 1, the end sealing water disc 36 is positioned below the end sealing spray pipe 34, and the end sealing water drain pipe is communicated with the bottom end of the end sealing water disc 36. The water is sprayed from the end seal spray pipe 34 to clean the outer side surface of the end seal cushion block 31 or the end seal foam 32, is collected by an end seal water tray 36 positioned below the end seal cleaning flow passage, and is discharged outside through an end seal drain pipe. The end sealing water tray 36 and the end sealing drain pipe are arranged, so that the cleaning wastewater can be conveniently collected and discharged.
Through configuration end seal spray pipe 34, when wasing the ink intracavity portion, still wasing the lateral surface of the end seal cushion block 31 of ink chamber through end seal spray pipe 34, wasing more thoroughly, can avoid the lateral surface long-term ink accumulation of end seal cushion block 31 and the region that the heated melting drops to the cardboard place down in the inking roller 45 during operation. In this embodiment, the end seal nozzle 34 is also connected to the JSG via a tee, and when the JSG cools and supplies water to the inking roller 45, water is supplied to the end seal cleaning flow passage at the same time, simplifying the piping arrangement.

The end seal 33 is provided to reduce the water splash and the influence of the cleaning water on the environment.
The end sealing baffle 33 is connected with the ink beam 1 through an adjustable structure, and the adjustable structure enables the end sealing baffle 33 to be adjustable along the width direction, so that cleaning water can fall into a water receiving disc when the end sealing cushion block 31 and the end sealing foam 32 are cleaned. The adjustable structure comprises a positioning groove 331 and a positioning screw 35, wherein the positioning groove 331 is arranged on the end sealing baffle 33 along the front-back direction, and the positioning screw 35 penetrates through the positioning groove 331 to be in threaded connection with the ink beam 1. Thus, the position of the end seal plate 33 can be adjusted by loosening the positioning screw 35, and the position of the end seal plate 33 can be adjusted during installation, thereby reducing splashing of the cleaning water.
In this embodiment, the ink chamber is closed on both sides by the end seals, and a doctor blade assembly is provided to close the underside of the ink chamber. Specifically, the ink beam 1 is further provided with a scraper assembly, the scraper assembly comprises a soft scraper 41, a compression screw 42 and a pressing block, the ink beam 1 is provided with a screw hole, and the compression screw 42 penetrates through the pressing block to be in threaded connection with the screw hole, so that the soft scraper 41 is pressed on the Mo Liang. The pressing screw 42 presses the soft scraping plate 41 on the ink beam 1 through the pressing block, so that the contact area when the soft scraping plate 41 is pressed is increased, and the risk of the soft scraping plate 41 being pressed is reduced. In a state where the inking roller 45 is mounted, the inking roller 45 is respectively abutted against the ink beam 1, the soft scraping plate 41 and both ends to form a relatively closed ink cavity. By supplying ink into the ink chamber, inking can be performed during rotation of the inking roller 45.
The doctor assembly further comprises a backing plate 44, the backing plate 44 is located on the side of the compression screw 42 facing away from the flexible blade 41, and the backing plate 44 is pressed against the ink beam 1 by a pressing block. By disposing the pad 44, when the pressing plate 43 presses the soft scraping plate 41 against the ink beam 1, the other side of the pressing plate 43 is limited by the pad 44, so that the pressing depth of the pressing block can be limited, and the pressing force of the pressing block can be balanced, so that the pressing block and the soft scraping plate 41 tend to be in plane contact, and the contact area between the soft scraping plate 41 and the pressing plate 43 is increased. The soft blade 41 is made of plastic. The soft blade 41 is made of plastic, has low cost and is not easy to wear the inking roller 45.
