Description

Technical Field

[0001] The utility model relates to the technical field of net curtain processing, in particular to a tensioning device for composite fiber net curtain processing. Background Art

[0002] Composite fiber is a kind of multi-component fiber, which is a term for artificial fiber varieties. There are two or more unmixed polymer fibers on the same fiber cross section. Composite fiber mesh curtain is a mesh curtain woven with composite fibers. The mesh curtain needs to be straightened during processing. If the tension of the straightened mesh curtain does not meet the processing requirements, a tensioning device is used to assist the processing.

[0003] The Chinese patent publication number is CN212503059U, and the authorization announcement date is February 9, 2021. A mesh curtain tensioning device with an improved structure includes a winding roller, an unwinding roller, and a tensioning structure. The tensioning structure includes a mounting bracket, and a tensioning roller is horizontally rotatably connected to the mounting bracket. The tensioning roller is axially parallel to the winding roller and is driven downward by a driving assembly so that its circumference is pressed against the surface of the mesh curtain. The beneficial effects of the utility model are as follows: the mesh curtain has a certain tension by pressing the tensioning roller against the surface of the mesh curtain. At the same time, the tensioning roller is driven downward by the driving assembly to adjust the tensioning force of the tensioning roller on the surface of the mesh curtain. The connecting part is driven vertically by the driving element to rotate the rotating arm along the hinge with the vertical pole, so that the tensioning roller can rotate along the hinge with the vertical pole, so that the tensioning roller is away from the surface of the mesh curtain, which is convenient for workers to clean foreign objects such as melt slurry blocks adhering to the tensioning roller.

[0004] During the processing of existing mesh curtains, the mesh curtain is straightened by unwinding and rewinding rollers. As the thickness of the mesh curtain changes on the unwinding rollers and the rewinding rollers, the angle of the straightened mesh curtain changes, and the pressure between the tensioning mechanism and the mesh curtain changes accordingly. The tensioning mechanism is not easy to adjust, and the tension of the mesh curtain cannot be accurately controlled, which reduces the tensioning effect of the mesh curtain and cannot meet the use requirements.
