Paper feeding mechanism and printing equipment

A printing equipment comprising a paper feeding mechanism, the paper feeding mechanism comprising:

• a main body;
• a paper feeding component on a side of the main body, the paper feeding component comprising a paper feeding tray and a paper lifting tray, both of the paper feeding tray and the main body surround to form a paper storage cavity, the paper feeding tray rotatably connecting with the main body, one end of the paper lifting tray rotatably connecting with the paper feeding tray, another end of the paper lifting tray comprising a guide rod slidably connected with the paper feeding tray, and the paper lifting tray rotating away from the paper feeding tray to drive the guide rod to move away from the paper feeding tray;
• a limiting component connected with the main body, the limiting component comprising a limiting member and a driving component, the limiting member abutting against the guide rod to resist the paper lifting tray rotating away from the paper feeding tray;
• wherein, the guide rod disengages from the limiting member and moves to a side of the limiting member away from the paper feeding tray when the paper feeding tray rotates away from the main body, and the driving component drives the limiting member to rotate to a side of the guide rod away from the paper feeding tray to make the limiting member abut against the guide rod, and drives the limiting member to lead the guide rod to move towards the paper feeding tray, thereby driving the paper lifting tray to rotate towards the paper feeding tray.
