Description

Technical Field

[0001] This utility model relates to the field of doctor blade chamber ink recovery technology, and in particular to a doctor blade chamber ink recovery structure. Background Technology

[0002] Doctor blade chambers are commercially used in a variety of printing processes, such as letterpress or offset printing. Doctor blade chamber systems offer better control over ink film thickness, color consistency, ink consumption, cleaning costs, and printing press uptime. A doctor blade system uses two doctor blades and a closed doctor blade chamber to distribute ink to the anilox roller. One of the doctor blades acts as a scraper blade, removing excess ink from the anilox roller, while the other acts as a sealer blade, keeping the ink within the doctor blade chamber.

[0003] The ink in the doctor blade chamber is pumped into the doctor blade chamber by an ink pump. When the ink level in the doctor blade chamber rises, it flows back into the ink tank through the ink outlet, thus forming an ink circulation. However, the current ink recovery structure on the doctor blade chamber is relatively complex, and it is inconvenient to clean the recovery structure later. Furthermore, the complexity of the recovery structure increases the length of the ink recovery pipe, which leads to a lot of ink adhering to the inner wall of the recovery pipe, resulting in ink waste.

[0004] The technical problem to be solved by this application is: to design a doctor blade cavity ink recovery structure that is easy to clean and reduces ink waste. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a doctor blade cavity ink recovery structure that is easy to clean and reduces ink waste.

[0006] The technical solution adopted by this utility model is as follows: a doctor blade chamber ink recovery structure, including a doctor blade chamber, the doctor blade chamber is provided with a plurality of ink inlets communicating with it, the doctor blade chamber is also provided with an ink outlet, the ink outlet is located between the top and bottom of the doctor blade chamber, and the ink outlet is provided with a return ink pipe communicating with it.

[0007] In some embodiments, a rubber sealing block and a wool felt are respectively provided at both ends of the doctor blade cavity, with the rubber sealing block located at the end that contacts the ink in the doctor blade cavity.

[0008] In some implementations, an ink tank is provided at the outlet end of the ink return tube, and an ink pump is installed inside the ink tank.

[0009] In some implementations, the ink pump is provided with an ink inlet tube connected thereto, one end of which is connected to the ink inlet.

[0010] In some embodiments, a return ink cartridge connected to the outside of the scraper cavity is also provided.

[0011] The utility model discloses a technical effect has as follows: be equipped with ink outlet in scraper cavity, ink outlet only is equipped with one back ink pipe that communicates with it, when the ink liquid level of scraper cavity rises, the ink in scraper cavity overflows to back ink pipe through ink outlet at this moment, then back flows to ink bucket through back ink pipe, through only one back ink pipe can complete the ink recovery circulation in scraper cavity, thereby greatly simplifies the ink recovery structure, and only uses one back ink pipe compared with the multiple back ink pipes of prior art, equivalent to greatly shorten the length that ink recovery structure ink flows through, makes the cleaning of ink recovery structure more simple and time -saving in later period, can also reduce the residual amount of adhering in ink recovery pipeline, avoids too much ink adhering in the inner wall of ink recovery structure and causes waste, and also can save water when cleaning.
