[0002] The mesh-drawing machine is a wire mesh machine that can achieve high-efficiency production. It is divided into two types: stretched mesh and punched mesh. The mesh-drawing machine is used to make metal sheets into a mesh structure. The cutter makes reciprocating motion in both horizontal and vertical directions, cuts alternating cuts on the metal sheet and stretches it, pulling the metal sheet into a grid shape.

[0003] Existing mesh-drawing machines are fed manually by pushing the metal plate into the mesh-drawing machine. If the time intervals for manually pushing the metal mesh are inconsistent, the mesh structures of the metal plate processed in the mesh-drawing machine will be large or small, making the metal mesh processing not meet the standards.
