Abstract

A paper feeding mechanism and a printing equipment are disclosed. The paper feeding mechanism includes a main body, a paper feeding component and a limiting component, where the paper feeding component includes a paper feeding tray and a paper lifting tray, the paper feeding tray and the main body are surrounded to form a paper storage cavity and the paper feeding tray is rotatably connected with the main body, the paper lifting tray rotates away from the paper feeding tray and drive a guide rod to move away from the paper feeding tray, the limiting component includes a limiting member and a driving component, the limiting member abuts against the guide rod to resist the paper lifting tray rotating away from the paper feeding tray.

First claim

What is claimed is:

1 . A 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 rotating 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.

2 . The paper feeding mechanism according to claim 1 , wherein the limiting member comprises a swinging portion and a rotating portion, both the swinging portion and the rotating portion are rotatably connected with each other, in response to the limiting member being located between the guide rod and the paper feeding tray, the swinging portion swings towards the guide rod, one end of the guide rod towards the paper feeding tray abuts against the rotating portion, the rotating portion rotates around the swinging member, and the swinging portion drives the rotating portion to move to a side of the guide rod away from the paper feeding tray and abut against one end of the guide rod away from the paper feeding tray.

3 . The paper feeding mechanism according to claim 2 , wherein the limiting component comprises a repositioning member, one end of the repositioning member is connected with the swinging portion, another end of the repositioning member is connected with the rotating portion, the swinging portion drives the rotating portion to move from a side of the guide rod towards the paper feeding tray to the side of the guide rod away from the paper feeding tray, and the repositioning member drives the rotating portion to rotate away from the guide rod for reposition.

4 . The paper feeding mechanism according to claim 1 , wherein the paper feeding mechanism comprises a sensor on the main body, the sensor is triggered in response to the paper feeding tray rotating away from the main body, and the sensor triggers the driving component to drive the limiting member to rotate.

5 . The paper feeding mechanism according to claim 1 , wherein the main body comprises a base arranged under the paper feeding tray, and a mounting base arranged above the base and located on a side of the paper feeding component, the base and the paper feeding tray are surrounded to form a paper storage cavity, the mounting base is rotatably connected with the paper feeding tray, the mounting base has a first guiding groove, and the paper feeding tray has a guiding member slidably connected with the first guiding groove.

6 . The paper feeding mechanism according to claim 5 , wherein the limiting component is installed on the mounting base, the driving component comprises a driver, a worm, a worm wheel and a transmission component, one end of the worm is connected with the driver, another end of the worm is connected with the worm wheel, one end of the transmission component is connected with the worm wheel, and another end of the transmission component is connected with the limiting member.

7 . The paper feeding mechanism according to claim 1 , wherein the paper feeding tray has a second guiding groove at one end of the paper feeding tray far away from a rotating connection position of the paper feeding tray and the paper lifting tray, and the guide rod is slidably connected with the second guiding groove.

8 . The paper feeding mechanism according to claim 1 , wherein the paper feeding mechanism comprises an elastic member between the paper feeding tray and the paper lifting tray, and the elastic member drives the paper lifting tray to rotate away from the paper feeding tray.

9 . The paper feeding mechanism according to claim 1 , wherein two opposite ends of the paper lifting tray respectively have a connecting portion extending outward therefrom, the paper feeding tray has a groove corresponding to a respective connecting portion, and the connecting portion is inserted into a respective groove to rotate relative to the respective groove.

10 . 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 rotating 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.

11 . The paper feeding mechanism according to claim 10 , wherein the limiting member comprises a swinging portion and a rotating portion, both the swinging portion and the rotating portion are rotatably connected with each other, in response to the limiting member being located between the guide rod and the paper feeding tray, the swinging portion swings towards the guide rod, one end of the guide rod towards the paper feeding tray abuts against the rotating portion, the rotating portion rotates around the swinging member, and the swinging portion drives the rotating portion to move to a side of the guide rod away from the paper feeding tray and abut against one end of the guide rod away from the paper feeding tray.

12 . The paper feeding mechanism according to claim 11 , wherein the limiting component comprises a repositioning member, one end of the repositioning member is connected with the swinging portion, another end of the repositioning member is connected with the rotating portion, the swinging portion drives the rotating portion to move from a side of the guide rod toward
