Description

Technical Field

[0001] The utility model relates to the technical field of strapping belt processing, in particular to a straightening mechanism applied to a strapping belt heating and shaping box. Background Art

[0002] Strapping tape is widely used in the packaging industry due to its advantages of good elastic recovery, high strength, good water resistance, strong chemical resistance, light weight and softness, etc. It is easy to use and low cost. In the production process of strapping tape, straightness is a testing standard for strapping tape. Generally, before heating and shaping the strapping tape, it needs to be straightened by a straightening device to improve the straightness of the strapping tape.

[0003] The straightening device is generally composed of a workbench, a fixed plate, a rotating shaft, a pressure roller, etc. Before the strapping tape enters the heating and setting box, it will be straightened by the pressure roller to avoid knotting in the heating and setting box, which will cause the produced strapping tape to be unqualified. For example, a Chinese patent discloses a straightening device for a strapping tape heating and setting box (authorization announcement number CN219112552U). This patented technology can straighten strapping tape bodies of different thicknesses, thereby improving the straightness of the strapping tape body after heating and setting, and improving the processing success rate of the strapping tape body;
