[0002] Chinese patent document CN215797486U discloses a paper feeding device for printing equipment, including a support frame, a support plate, and a paper suction device. The bottom of the paper suction device is provided with a paper tray, and the bottom of the paper tray is provided with a pushing structure. The top of the paper tray is provided with a guiding structure. By engaging a limiting rod with a limiting groove, the paper tray is limited, allowing it to be stably positioned away from the paper suction device during feeding, thus facilitating feeding and not affecting its normal use. This improves the ease of use of the feeding device. Through the cooperation of a moving rod and a moving block, and with the support of a second and third spring forming a cross-shaped support at the bottom of the paper tray, the paper tray moves more stably when pushed, ensuring stable paper movement when pushed upwards. This prevents unstable paper tray movement from affecting paper placement, facilitating the paper suction device to pick up sheets one by one, and also protecting the paper, ensuring the practicality of the feeding device.

[0003] When the paper feeding device of the above-mentioned printing equipment is in use, the cardboard stack is pushed upward by the spring. Since the effective stroke of the spring is limited, the amount of cardboard that can be placed at one time is small. In addition, when the suction cup presses down to suck up the paper, the spring will be subjected to force and shake up and down, which reduces the stability of the device. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic paper feeding device for printing, which can solve the problem that when the paper feeding device for printing equipment is used, the cardboard stack is pushed upward by the spring. Due to the limited effective stroke of the spring, the number of cardboard stacks that can be placed at one time is small. In addition, when the suction cup presses down to suck up the paper, the spring will be forced to shake up and down, which reduces the stability of the device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic feeding device for printing paper, comprising a support base, a lifting mechanism, and a blocking mechanism.
