A sliding chain belt and a sliding chain

By setting through holes and optimizing the fabric structure on the sliding chain belt, and combining the injection molding of the main chain teeth to form anchor posts, the problem of arching deformation in the chain tooth area caused by fabric shrinkage during sewing is solved, achieving a balance between the stability and flexibility of the sliding chain belt, and improving the appearance of the garment and the sewing effect.

AI Technical Summary

Technical Problem

In existing technologies, the shrinkage of the fabric tape during sewing causes the chain teeth area to arch and deform, affecting the appearance of the garment.

Method used

Through holes are arrayed along the length of the conveyor belt, and combined with specific fabric structures, such as 2/2 warp-broken twill and 2/2 weft-ply plain weave, the distance ratio between the mounting holes and the belt ribs is optimized. Anchor posts are formed by injection molding the teeth of the main chain, which enhances stability and flexibility.

Benefits of technology

It effectively prevents arching and deformation in the chain tooth area, improves the longitudinal elasticity and elongation of the sliding belt, reduces the risk of deformation, and improves the sewing yield and the stability of the main chain teeth.

Abstract

The utility model discloses a kind of sliding chain belt and sliding chain, it is related to sliding chain field, wherein the sliding chain belt includes a pair of belt body oppositely arranged, a pair of belt body is set with band reinforcement close to the side of the other party, a pair of belt body is respectively provided with chain tooth area and sewing area along width direction, the area close to band reinforcement is chain tooth area, characterized in that, in chain tooth area, a plurality of mounting holes are provided along the length direction of belt body, female chain tooth connects the band reinforcement of a pair of belt body and is installed in chain tooth area, and a single female chain tooth covers at least one mounting hole. Sliding chain includes female chain, and the female chain includes the female chain tooth of setting in the chain tooth area of the above-mentioned sliding chain belt, the female chain tooth is injection molded in chain tooth area, and injection molding material penetrates chain tooth area and forms anchor column. The application effectively changes the longitudinal elasticity and expansion rate of sliding chain belt, and plays the role of preventing arching.
