Material feeding, distributing, and pushing mechanism of tying tool, automated tying tool, and automated tying method

An automated tying tool, comprising:

• a slider, a guide rail, a first guide claw, a second guide claw, a frame, a tensioning wheel, a cutter, a stepping feeding mechanism and a material pushing rod, wherein the first guide claw and the second guide claw are mounted on the frame via a rotation-center pin, the cutter and the tensioning wheel are mounted in the frame, the guide rail is adjacent closely to the frame, the slider cooperates with the guide rail and slides along a length direction of the guide rail, the first guide claw, the second guide claw, the slider and the guide rail are arranged to have symmetrical center planes located on a center plane of the automated tying tool, the stepping feeding mechanism is mounted on the frame or mounted on a housing of the automated tying tool, the stepping feeding mechanism is capable of loading a tie, and the tie is conveyed, in each binding cycle, according to a fixed interval, to a position where a symmetrical center plane of the tie is coincident with a center plane of the automated tying tool, the material pushing rod is mounted on the frame or the housing of the automated tying tool, the material pushing rod pushes the tie located on the center plane of the automated tying tool to the slider to be pre-positioned, and the slider drives the tie to slide from the pre-positioning position to a binding operation position.
