Description

Technical Field

[0001] The utility model relates to the technical field of slitting machine accessories, in particular to a slitting machine tensioning device. Background Art

[0002] Slitting machine, also known as slitting line, slitting machine, slitting machine, is used to unwind, roll, shear, and tighten metal coils into multiple strips of required width. It is suitable for processing cold-rolled and hot-rolled carbon steel, silicon steel, tinplate, stainless steel, and various metal materials after surface coating. Traditional slitting machines disperse the materials after shearing, which makes the coils easy to deviate or not dense when winding, affecting the winding quality.

[0003] For example, a new type of longitudinal shearing machine winding device with publication number CN210632682U includes a connecting seat detachably connected to the winding machine, a winding rod fixedly arranged on the connecting seat and a pneumatic tensioning device arranged on the surface of the winding rod, and also includes a plurality of winding cores, gaskets and pads sleeved on the winding rod, the end of the winding rod is provided with a threaded column extending along its length direction, and a clamping nut is threadedly provided on the threaded column, and the winding core, gasket and pad between the connecting seat and the clamping nut are clamped and arranged by rotating the clamping nut. Since the utility model is provided with multiple winding cores, winding cores with different outer diameters can be used for coils with different inner diameters, and strips with different inner diameters can be produced at one time without transferring to the next process, and can be directly circulated as finished products, thereby reducing production costs such as materials, personnel and energy.

[0004] In actual application, the above technical solution has the problem that the material dispersion tension is insufficient and the inverted winding is not dense.

[0005] Therefore, it is necessary to invent a tensioning device for a slitting machine to solve the above problems. Utility Model Content
