Description

Technical Field

[0001] The utility model belongs to the technical field of containers for containing cigarette steel-printed ink, and in particular relates to a novel cigarette steel-printed ink injection plug and an injection ink cylinder. Background Art

[0002] Cigarette stamping is the process of printing patterns and texts on cigarettes by injecting ink using a cigarette-making machine, and the cigarette stamping ink is usually stored in an injection ink cylinder.

[0003] The prior art cigarette steel stamp ink injection cylinder, such as the small cigarette steel stamp ink injection cylinder disclosed in the Chinese patent with authorization announcement number CN2879687Y, includes a cylinder body and a plug. An injection nozzle is provided on one end face of the cylinder body, and the plug is installed in the inner cavity of the other end of the cylinder body. A sealing ring is provided on the cylindrical surface of the plug, and a top pressure plate is embedded on the outer end face. This plug is usually processed into one piece by rubber and plastic or by rubber and iron block. The processing is relatively convenient, but affected by the mold opening time and rubber shrinkage, in actual use, the plug cannot be pushed in the cylinder body or a gap appears between the plug and the cylinder body, resulting in ink leakage.

[0004] The prior art cigarette stencil ink injection cylinder is also disclosed in the Chinese patent with the authorization announcement number CN201957748U, which includes a cylinder body and a hollow cylindrical injection plug. The hollow cylindrical injection plug is installed in the inner cavity at the other end of the cylinder body. There are multiple sealing rings on the outside of the hollow cylindrical injection plug, which can achieve smooth operation in the inner cavity of the cylinder body without tipping over or ink leakage. This hollow cylindrical injection plug is usually processed by an opening and closing mold. The opening and closing mold usually requires multiple openings and closings. The opening and closing movements of the mold will introduce certain tolerances. These tolerances may affect the overall accuracy of the mold, resulting in the outer circumference of the hollow cylindrical injection plug. The precision is not high. When it is installed in the cylinder body, it will be too tight or too loose, and it will still be unable to be pushed and the ink will leak. Utility Model Content
