[0002] The wavy wire mesh includes wavy wires and dragging ribs at the bottom of the wavy wires, and side ribs welded to the wavy wires are arranged on both sides of the wavy wires, and end ribs welded to the dragging ribs are arranged at both ends of the wavy wires. The patent number is: 202311853349.5, and the patent name is: The patent of the wavy wire production device for the storage rack mesh and the method of producing wavy wires with the device discloses a wavy wire bending and wire feeding mechanism, and the wire feeding mechanism includes two lower combing tooth plates parallel to each other in the front-to-back direction arranged on the fixed frame, and the lower combing tooth plate is provided with a lower combing tooth groove opening upward, and the lower combing tooth plate is connected to the fixed frame through a lower combing tooth plate lifting mechanism, and an upper combing tooth plate frame is arranged above the lower combing tooth plate, and two parallel upper combing tooth plates that can move forward and backward along the upper combing tooth plate frame are arranged on the upper combing tooth plate frame, and an upper combing tooth groove opening downward is arranged on the upper combing tooth plate, and the upper combing tooth plate frame is connected to the fixed frame through an upper combing tooth plate frame lifting mechanism. The upper comb tooth plate is pressed down, so that the bent wavy wire enters the upper comb tooth groove of the upper comb tooth plate, and the lower comb tooth plate moves downward, so that the bent wavy wire disengages from the lower comb tooth groove, and the upper comb tooth plate drives the bent filament to move forward the length of two "U"-shaped filament distances. At this time, the 90-degree bend of the filament just bypasses the second right bending column from the right side of the second right bending column; the lower comb tooth plate is pushed up, so that the bent wavy wire enters the lower comb tooth groove, the upper comb tooth plate moves up, and the filament moves out of the upper comb tooth groove of the upper comb tooth plate, and the upper comb tooth plate moves backward the length of two "U"-shaped filament distances to reset. The above-mentioned wire feeding and bending device has the following defects: First, the lower comb tooth plate moves up and down, and the upper comb tooth plate not only moves up and down, but also moves back and forth, so the equipment is bulky and consumes a lot of energy; second, the wavy wire is located between the upper comb tooth plate and the lower comb tooth plate, and the openness of the equipment is poor. When tangled wires occur, it is not easy to be discovered, and the equipment is convenient to repair and maintain; third, the lower comb tooth plate moves up and down, and the upper comb tooth plate not only moves up and down, but also moves back and forth, so the reciprocating efficiency is low and the mesh welding efficiency is low.

A power mechanism, a wire feeding gear is arranged on the wire feeding frame body, a wire feeding chain is arranged on the wire feeding gear, and a limited position paddle is arranged on the wire feeding chain. The wire feeding power mechanism includes a chain push-pull rod located in front of the wire folding and pushing frame, the chain push-pull rod is fixed to the power chain, the power chain passes around the one-way transmission sprocket, the transmission shaft of the one-way transmission sprocket is connected to the power of the wire feeding gear, and the straightened metal wire is bent into a wavy wire through the wire folding mechanism; the lifting cylinder drives the front end of the push plate to swing upward; so that the lower end of the push plate is higher than the upper edge of the wavy wire; the first motor drives the lead screw to rotate, so that the wire folding and pushing frame moves backward, the chain push-pull rod in front of the wire folding and pushing frame moves backward, drives the upper end of the power chain to move backward, and the one-way transmission sprocket The first motor drives the lead screw to rotate, so that the wire folding and wire pushing frame moves forward, drives the push plate and the wavy wire in the limit slot of the push plate to move forward, and the chain push-pull rod in front of the wire folding and wire pushing frame moves forward, drives the upper end of the power chain to move forward, and the one-way transmission sprocket drives the transmission shaft and the wire feeding gear to rotate, drives the wire feeding chain, the limit paddle and the wavy wire to move forward, and the wavy wire in the limit slot moves forward along the wire pushing support plate, and the front end surface of the wavy wire presses against the rear end of the limit spring piece, so that the limit spring piece moves up, and the wavy wire is stuck in the temporary limit slot at the lower end of the limit spring piece;The chain push-pull rod in front of the wire folding and pushing frame moves forward, driving the upper end of the power chain to move forward, the one-way transmission sprocket drives the transmission shaft and the wire feeding gear to rotate, driving the wire feeding chain and the limit paddle to move forward, and the wave wire in the temporary limit groove at the front enters between the adjacent limit paddles of the chain and is pushed forward by the limit paddle at the rear. The wave wire in the temporary limit groove pushes the limit spring piece forward, and the lower end of the limit spring piece swings forward and upward, so that the wave wire in the temporary limit groove moves forward from the temporary limit groove, and the limit spring piece returns to its original position under its own elastic force, and the next wave wire enters the temporary limit groove from the rear; the bent wave wire is sent to the welding head position by the limit paddle of the wire feeding chain and welded with the longitudinal wire to form a mesh. ;
