Stamp-pad ink mechanism and rolling printing stamping device with stamp-pad ink mechanism

Abstract

The invention discloses a stamp-pad ink mechanism and a rolling printing stamping device with the stamp-pad ink mechanism. The stamp-pad ink mechanism comprises an oiling roller used for smearing stamp-pad ink on the surface of a stamp and further comprises an oil injection roller used for injecting oil to the oiling roller, wherein the oil injection roller is sleeved with the oiling roller, a cavity used for storing the stamp-pad ink is arranged in the oil injection roller, and an oil leakage opening communicated with the cavity and used for adding the stamp-pad ink to the oiling roller is formed in the roller surface of the oil injection roller. Compared with the prior art, the stamp-pad ink is stored in the oil injection roller and permeates to the oiling roller through the oil leakage opening, and the problem that in the prior art, when a brush is used for brushing stamp-pad ink to the surface of the oiling roller, the oiling reliability is poor because of abrasion of the brush is avoided; besides, the stamp-pad ink is stored in the cavity of the oil injection roller, foreign matter such as dust is prevented from falling into the stamp-pad ink, and therefore the stamping quality is guaranteed.

Description

technical field [0001] The invention relates to an ink printing mechanism and a roll printing and stamping device with the ink printing mechanism. Background technique [0002] Traditional bills, such as invoices and bank business documents, are usually manually stamped one by one after printing. In order to improve work efficiency and reduce the labor intensity of the operator, a rolling stamping device has appeared at present. [0003] Such as figure 1 As shown, the device includes a pressing roller 1', a driving roller 2', a stamp 3', an oiling roller 4', and a mimeograph box 8', wherein the stamp 3' is arranged on the driving roller 2', and the oiling roller 4' It is set under the driving roller 2', and the pressure roller 1' is set above the driving roller 2'. When the driving roller 2' rotates, it can drive the stamp 3' to rotate. 1' fit together; the mimeograph box 8' is set under the oiling roller 4', and a rotating shaft 6' is arranged in the mimeograph box 8', a...

Problems solved by technology

[0004] The problem with this roll printing and stamping device is that the brush 7' will be shortened after long-term use, and will fall off in serious cases, so it cannot be guaranteed that the printing oil in the mimeograph box 8' will be evenly brushed on the oiling roller 4' In addition, because the oiling roller 4' is in contact with the brush 7' in the oiling box 8', a gap needs to be set between the oiling box 8' and the oiling roller 4', and foreign matter such as dust may be caused by The gap falls into the 8' of the mimeograph box, which affects the quality of the seal
