Description

Technical Field

[0001] The utility model relates to auxiliary production equipment for lifting belts, in particular to a yarn dipping device for sewing high-strength flat lifting belts. Background Art

[0002] Conventional lifting belts (synthetic fiber lifting belts) have multiple advantages such as high strength, wear resistance, oxidation resistance, and UV resistance. At the same time, they are soft, non-conductive, and non-corrosive (no harm to the human body). They are widely used in various fields such as ships, metallurgy, machinery, mining, petroleum, chemical industry, ports, electricity, electronics, transportation, and military. There are many types of lifting belts. According to the appearance of the lifting belt, they are divided into four categories: annular core-through, annular flat, double-eye core-through, and double-eye flat; according to the maximum load that can be safely borne, they can be divided into 1T load lifting belts, 2T load lifting belts, 3T load lifting belts, etc. 1T load lifting belts are 30mm wide, and the width of the load is a multiple of 25. 2T is 25x2=50mm wide, and 3T is 25x3=75mm wide, and the width of the load is a multiple of 30.

[0003] Flat lifting belts are mainly made of high-strength fabrics woven from nylon fibers, polyester fibers and polypropylene fibers, which are cut and sewn together. Conventional yarns, such as nylon yarns, polyester yarns and polypropylene yarns, are generally used for sewing. These yarns are used to sew multiple pieces of cut fabrics together. They are the most critical connection nodes of the lifting belts, and they are subjected to relatively large forces when the lifting belts are used. They are prone to breakage due to uneven force, and then partial tearing of the lifting belts, which seriously affects the service life of the lifting belts. Utility Model Content
