AI Technical Summary
In the prior art, the fan-ring paper sheet is raised during the paper-down process due to touching the edge of the paper rack's material outlet, resulting in the pushing claws in the material pushing process that cannot accurately grasp both ends of the paper sheet, affecting the orderly progress of the equipment.
A paper-down mechanism is designed, including a liftable suction rod set and an internally and externally flipped paperboard. The suction rod group absorbs the fan annular paper sheet and lowers it to the paper-connecting platform. The pressing board flips the two ends of the paper sheet under the linkage of the suction rod group to ensure its flat state.
By flattening both ends of the fan annular paper sheet, the improved paper-down mechanism allows the pushing claws to accurately push the paper feed, improving the orderliness and efficiency of the equipment.

BRIEF DESCRIPTION OF THE DRAWINGS
[0010] The specific embodiments of the present utility model will be further described in detail below with reference to the accompanying drawings.
[0011] Figure 1 It is a schematic structural diagram of the present utility model.
[0012] Figure 2 It is a side view of the structure of the present utility model. SPECIFIC EMBODIMENTS
[0013] The drawings show the structure of the present utility model, and its related details will be further described below with reference to the drawings. In this embodiment, referring to the attached Figure 1-2 , the paper feeding mechanism includes a paper receiving platform 1. Above the paper receiving platform 1, there is a storage platform 2. On the storage platform 2, there is a paper rack for storing stacked fan-shaped paper sheets. Corresponding to the storage platform 2, there is a paper rack blanking opening 21. A material suction rod group 3 that can perform lifting and left-right arrangement is penetrated through the paper receiving platform 1. The suction nozzle end of the material suction rod is matched with the paper rack blanking opening 21. Preferably, the material suction rod group 3 includes two material suction rods, corresponding to the left and right ends of the blanking opening 21 respectively. Pressing paper boards 4 are respectively arranged on the left and right sides of the material suction rod group 3. The pressing paper boards 4 can be turned inside and outside on the paper receiving platform 1. The pressing paper boards 4 and the paper receiving platform 1 cooperate with each other to flatten the two ends of the fan-shaped paper sheet.
[0014] The working principle of the present utility model is as follows: the fan-shaped paper sheets are stacked in the paper rack. The material suction rod group 3 rises, and the corresponding suction nozzles adsorb the bottommost fan-shaped paper sheet. Then the material suction rod group 3 descends, and takes the fan-shaped paper sheet away from the paper rack blanking opening 21 until it descends and releases it onto the paper receiving platform 1. Then the pressing paper board 4 turns inwards, approaches the paper receiving platform 1, and leaves a certain gap with it, cooperating with the paper receiving platform 1 to flatten the two ends of the fan-shaped paper sheet for the pushing claws to accurately push the paper for feeding.
[0015] As a further improved specific implementation method, the paper pressing paper 4 is linked with the suction rod group 3; preferably, the suction rod group 3 is arranged on the lifting seat 5, and the lifting seat 5 is equipped with a lifting power source, the paper pressing paper 4 is arranged on the rotating shaft 6, and the rotating shaft 6 can be rotatably arranged on the shaft seat, and a gear 61 is provided at one end of the rotating shaft 6, the gear 61 is meshed with the rack 7, the rack 7 can be lifted and lowered, and a driving long groove 71 is provided at the lower section of the rack 7, and a driving block 51 is provided on the corresponding lifting seat 5, and the driving block 51 can be lifted and moved in the driving long groove 71, and can drive the rack 7 to lift; specifically, a slide rail 72 is provided on the back of the rack 7, and the slide rail 72 is equipped with a slide seat 8, and the slide seat 8 is arranged on the paper receiving platform 1, and a slider 73 is also provided on the rack 7, and the slider 73 is sleeved on the column 9, and the slider 73 is equipped with a support spring 91, and the support spring 91 is sleeved on the column 9.
[0016] During operation, the suction rod group 3 moves up with the lifting seat 5 to absorb the fan-shaped paper piece, and then the suction rod group 3 moves down with the lifting seat 5 to release the fan-shaped paper piece to the paper receiving platform 1. In this process, the driving block 51 of the lifting seat 5 moves in the driving long groove 71 of the rack 7, and the rack 7 remains stationary under the action of the supporting spring. As the lifting seat 5 continues to move down, the driving block 51 touches the bottom end of the driving long groove 71, and the corresponding rack 7 moves down accordingly. The rack 7 acts on the gear 61 to drive the rotating shaft 6 to rotate, and the corresponding paper pressing paper 4 flips inward to complete paper pressing; conversely, the lifting seat 5 moves up, and the driving block 51 moves in the driving long groove 71 of the rack 7 until it touches the top of the driving long groove 71, and the corresponding rack 7 moves up accordingly. The rack 7 acts on the gear 61 to drive the rotating shaft 6 to reverse, and the corresponding paper pressing paper 4 flips outward to avoid the suction rod group 3 from moving up.
[0017] As a further improved specific implementation, the paper pressing paper 4 is eccentrically arranged on the rotating shaft 6 , so that the turned paper pressing paper 4 is closer to the paper receiving platform 1 .
[0018] In summary, the above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
