Description

Technical Field

[0001] The utility model relates to the technical field of tensioning devices, and more specifically to a tensioning device for coating decorative printed foil on textiles. Background Art

[0002] In the production process of textile decorative printing foil coating, the control of tension is crucial to ensure the quality of printing. The textile needs to maintain a stable tension during the coating process to ensure that the coating or ink is evenly distributed on the textile and avoid wrinkling, deflection or deformation, which will affect the clarity and integrity of the printing. In addition, impurities such as dust and fiber scraps that may exist on the surface of the textile will also have an adverse effect on the printing effect.

[0003] The Chinese patent with publication number CN217732161U discloses a cloth winding device with a tensioning assembly. The applicant believes that the above device tensions the cloth through a tensioning mechanism during the cloth winding process, but the tensioning force relies heavily on the elastic force provided by the telescopic spring to apply pressure. Due to the different material properties of different cloths, the tensioning force required during the winding process is often different. Providing tension only through the elastic force of the spring may not meet the winding requirements of a variety of cloths. At the same time, the above device lacks a cleaning structure for the cloth surface, making it difficult to control the quality of the cloth after winding. In response to the above problems, the present device was invented. Utility Model Content
