[0007] The swing of the swing frame and the movement of the movable baffle are driven by a linkage component, which includes a rotating shaft, which is rotatably arranged on the feeding bracket, a pushing block is installed on the shaft end of the rotating shaft and is connected to the cylinder, the upper end of the movable baffle is fixedly connected to the rotating shaft, and a clamping block is fixedly arranged on the rotating shaft, and the clamping block and the swing frame are connected by a connecting rod.

[0008] A material diverting device is provided at the output side of the first and second material supporting platforms. The material diverting device comprises a rotating body and a plurality of box bins arranged along the circumference of the rotating body. The box bins have lateral openings. The rotating body is driven by a rotating body motor to perform indexing circular rotation.

[0009] After adopting the above technical scheme, the utility model can be used for feeding paper before bagging and packaging, with high working efficiency. The specific action process is: after the paper is cut longitudinally and transversely on the paper cutter, it is pushed to the entrance of the paper feeding device, and then sent to the temporary storage bin by the paper feeding device and supported by the bottom support plate of the temporary storage bin. At this time, the multiple first paper pushing bins surrounded by the first pushing block group are respectively located at the bottom of the multiple temporary storage bins and correspond to each other, and the second paper pushing bins surrounded by the second pushing block group follow the rear ends of the multiple first paper pushing bins; in the above state, the bottom support plates of the multiple temporary storage bins are opened at the same time, so the papers in the multiple temporary storage bins will fall into the corresponding first paper pushing bins at the same time, and then the support plates return to their positions, and the temporary storage bin receives the papers sent by the paper feeding device again, and at the same time the first servo motor drives the first transmission The first paper pusher pushes the paper out of the bottom of the temporary storage bin and reaches the output side of the first and second supporting platforms. Then, through the stepping transmission of the first transmission chain, the paper in each first paper pusher is sequentially sent into the box bin of the material diverting device. After the paper is diverted, it is continued to be transported for bagging (to avoid scratches on the surface of the paper). After the first paper pusher pushes the paper out of the bottom of the temporary storage bin, the second servo motor drives the second transmission chain to make the second paper pusher reach the bottom of the temporary storage bin and wait for the bottom support plate of the temporary storage bin to open again for paper unloading. After the first paper pusher completes the unloading of the paper to the material diverting device, it arrives at the rear end of the second paper pusher to wait under the drive of the first servo motor. In this cycle, the feeding of the paper before bagging can be completed efficiently. During the above-mentioned action process, the first and second supporting platforms are set to support the paper when the first and second paper pushers push the paper, so as to keep the paper stable and reliable when being pushed. In addition, during the above-mentioned action process, the paper feeding device can ensure the accurate position of the paper when it is fed out. When multiple stacks of paper on the paper cutter are pushed onto the lower conveyor belt at the same time, the lower conveyor belt feeds the paper forward. At this time, the movable baffle positions the paper as the front stop at the lower limit position, and then the cylinder pushes the swing frame downward. When the front end of the swing frame and the front conveyor wheel swing down, the front end of the upper conveyor belt will be close to the lower conveyor belt, and the movable baffle will be lifted upward at the same time. Therefore, under the joint push of the upper and lower conveyor belts, the paper is accurately delivered to the temporary storage bin. BRIEF DESCRIPTION OF THE DRAWINGS
