Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cigarette production equipment, in particular to an ink pump connecting device of a cigarette making machine printing system. Background Art
[0002] The function of the cigarette machine printing system is to print cigarette brands on cigarette paper. The cigarette machine printing system uses replaceable ink cartridges to feed ink. The ink in the ink cartridge is delivered to the ink supply nozzle through an ink pump. The ink supply nozzle then sprays the ink onto the ink distribution roller, and then the ink is delivered to the steel printing roller through a series of conveying devices. Finally, the ink is printed on the cigarette paper through the steel printing roller.
[0003] In the cigarette machine printing system, the connection between the ink pump and the ink cartridge is achieved through a connecting device. The existing connecting device has a matching hole on it, which matches the shape of the tapered ink outlet tube section at the outlet end of the ink cartridge. The ink outlet tube section of the ink cartridge is inserted into the matching hole of the connecting device, and the piston in the ink cartridge is pushed out by the push rod of the cylinder. The ink in the ink cartridge flows out through the ink outlet tube section and enters the matching hole, and enters the ink pump from the connecting channel connected to the matching hole. When the ink outlet tube section of the ink cartridge is worn and deformed or is not well aligned with the matching hole, ink often leaks out from the gap between the ink outlet tube section and the matching hole. The leaked ink not only contaminates the printing device, increases the difficulty of equipment maintenance and reduces the efficiency of equipment maintenance, but also drips onto the cigarette paper to contaminate the finished cigarettes, posing a great quality risk.
