The invention relates to a transverse beam device of a material guide chute of a mesh reinforcement welding production machine. The transverse beam device comprises machine frame side plates and transverse beams, wherein the machine frame side plates are arranged at intervals; the transverse beams are erected transversely; the machine frame side plate on each side is provided with a dragging plate mechanism of the material guide chute; each dragging plate mechanism of the material guide chute drives the transverse beam to move up and down; each transverse beam is correspondingly fixed on an adjusting plate of the dragging plate mechanism of the material guide chute on the corresponding side; and a plurality of guide plate mechanisms of the material guide chutes are fixed on the transversebeams. The invention has the advantages of simple structure, convenient installation and low production cost, is suitable for the mesh reinforcement welding production machine, replaces workers to weld, improves the welding efficiency, and ensures the welding quality of mesh reinforcements.
