Abstract

The utility model relates to the technical field of mesh belt operation, and discloses a mesh belt operation angle deviation preventing device which comprises a supporting table and is characterized in that a control assembly is arranged, when a circular plate is rotated at the top of a fixed frame, the circular plate can drive a threaded rod to synchronously rotate in the fixed frame, and when the threaded rod rotates, the threaded rod can rotate in the fixed frame, and therefore the mesh belt operation angle deviation preventing device can be achieved. The movable block can longitudinally move along the surface of the vertical plate, the pressing plate fixed to the surface of the movable block synchronously slides in the limiting frame, and when the movable block moves, the movable rod hinged to the surface of the movable block abuts against the surface of the fixed block. Therefore, when the movable rod abuts against the surface of the fixed block, the movable rod can be folded under the support of the torsion spring, so that the moving speed of the movable block and the flat plate can be slowed down, and the conditions of displacement and deviation caused by too high pressure applying speed when the mesh belts with different thicknesses are compatible are avoided.
