Ink chamber frame structure and ink chamber device with ink return function

An ink chamber frame structure combined with an ink roller to form an ink chamber device with an ink return function, said ink chamber frame structure comprising:

• an ink chamber frame comprising an upper ink chamber frame, a lower ink chamber frame and an ink shield formed integrally, said ink shield having an upper side thereof connected to said upper ink chamber frame component and an opposing lower side thereof connected to said lower ink chamber frame component, said ink shield having a front surface thereof disposed adjacent to said ink roller in such a manner that said ink roller has left and right ends thereof correspond to corresponding left and right ends of said ink shield;
• two first ink stopper blocks disposed on the front surface of said ink shield of said ink chamber frame and respectively located near the said left and right ends of said ink shield and near the said lower side of said ink shield, said two first ink stopper blocks each having a top and an opposing bottom;
• and
• a lower scraper disposed on said lower ink chamber frame component of said ink chamber frame, said lower scraper being incorporated with said ink shield of said ink chamber frame, said two first ink stopper blocks and said ink roller to form an ink chamber;
• wherein said two first ink stopper blocks are used to block an ink, and said ink chamber frame divides said ink chamber into a wiping area and two ink return areas using said two first ink stopper blocks as a dividing line, said wiping area being the area between said two first ink stopper blocks, said two ink return areas being the areas between the said left and right ends of said ink shield and said two first ink stopper blocks, said wiping area being used to accumulate an ink, the said ink accumulated in said wiping area flowing through the two tops of said two first ink stopper blocks and then flowing to said two ink return areas for recycling to avoid accumulation in the entire said ink chamber after the said ink accumulated in said wiping area exceeding the height of the two tops of said two first ink stopper blocks, so that when said ink roller is in use, the said ink is prohibited from overflowing between opposing left and right ends of said ink roller and the said left and right ends of said ink shield of said ink chamber frame.
