Conveyer belt edge gluing guiding and limiting device

The utility model discloses a conveyer belt edge gluing guiding and limiting device composed of a first guiding and limiting wheel, a second guiding and limiting wheel, a third guiding and limiting wheel and a limiting box, wherein the limiting box is internally provided with the first guiding and limiting wheel, the second guiding and limiting wheel and the third guiding and limiting wheel; the limiting box is connected to a rack of a welter; the surface of the first guiding and limiting wheel is meshed with a conveyer belt; the first guiding and limiting wheel is a concave wheel; the third guiding and limiting wheel is a convex wheel; and the second guiding and limiting wheel is a planar wheel. Problems and defects caused by the traditional manual gluing and welter gluing can be completely overcome through replacing manual operation with automatic operation; the limiting device is simple and reasonable in structural design, easy to operate, compact and level in edge gluing and capable of better reducing the
