The present invention is by above-mentioned structure, it is possible to being effectively improved the production efficiency of automatic code marking device, concrete reason is as follows: be placed into seriatim on sloping platform by commodity, sloping platform slide to guide rail, then slided on conveyer belt by guide rail; When commodity are placed into sloping platform, effect due to commodity gravity, causing that the first rotation bar left part declines, this can cause two parts to move: one is the decline of extension bar, and two is that the first arc-shaped rack of the first rotation bar right part pin joint on the first rotation bar rotates counterclockwise;
In the process that extension bar declines, extension bar can promote link rotatable, owing to connecting rod lower end is pushed against on projection left side wall, so connecting rod can promote projection to slide to the right in the process rotated, that is projection drives conveyer belt to move right to drive commodity to move right, so that commodity are delivered to lower section, top singly;
The rotation counterclockwise of the first arc-shaped rack can drive rotating clockwise of the second arc-shaped rack, that is the second rotation bar can rotate clockwise around its pin joint, so the second circular arc pushing block rotating bar right part also rotates clockwise around the second pin joint rotating bar, roller is rolled in arc chute and promotes push rod to decline along sleeve axis direction, that is push rod declines along sleeve axis direction, and then promote push pedal and top to decline with to the commodity stamp on conveyer belt, and the push pedal declined can pull open extension spring;
In reseting procedure, owing to sloping platform losing the effect of commodity gravity, namely the first rotation bar left part is not subjected to constraint, and push pedal is subject to the effect of tension spring tension and rises along guide rod axis, promoting push rod and roller to rise, the roller of push rod upper end rolls to promote circular arc pushing block to rotate around the second pin joint rotating bar in arc chute and resets, until the limited block on push rod is against pedestal, and second rotate bar reversion, thus first rotate bar also reverse; When first rotates and rise on bar left part, the rising of extension bar can be driven, and then pull connecting rod to rise, and connecting rod bottom can be moved to the left and return to initial position; In sum, each commodity is from landing sloping platform, and the action of projection all can occur once to promote to the right in connecting rod lower end, and the action of a stamp all can be there is in top, and then the continuous stamp completing commodity works, improve the efficiency of commodity stamp, and reduce the cost of stamp.
