Description

Technical Field

[0001] The utility model belongs to the technical field of tufting, and in particular relates to a detachable automatic tensioning base cloth device. Background Art

[0002] Tufted products are increasing day by day, and they are often used in the fields of floor and wall decoration. Tufted products are often made in the form of gun stabbing on the base fabric. Generally, before the tufting work begins, the tufted base fabric needs to be manually stretched on the stretcher frame. This will face a problem. If the tufted base fabric is to be stretched, the operator needs to first fix one side and then tighten the tufted base fabric and hang it on the nail strip. Generally, if the width of the tufted base fabric is relatively large, it needs to be stretched section by section. This phenomenon will affect the flatness and firmness of the tufted base fabric. When encountering this problem, most solutions are to have the operator manually re-tighten the tufted base fabric. The manual tightening method will have a great impact on the production efficiency of tufted product processing. Therefore, the tufting field requires equipment for automatically tensioning the base fabric. Summary of the invention
