[0002] There are two types of expansion devices for existing dipping machines, one is a screw expansion roller and the other is an arched rubber expansion roller. These two expansion rollers have obvious shortcomings when used together: the arched rubber expansion roller will cause the warp in the middle of the fabric to be subjected to greater force, while the warp on both sides of the fabric will be subjected to less force. At the same time, the screw expansion roller will continuously expand the cord fabric. When expanding, they will cause uneven force on the warp and weft, resulting in more or less edge density or weft skewness in the cord fabric after expansion.

[0004] The above technical solution has some problems in practical application. The width of the expanding roller in the technical solution is constant, and its processing range for the cord fabric is limited. Moreover, the force of the expanding roller on the cord fabric cannot be adjusted according to the actual situation.

[0005] Therefore, it is necessary to invent a cord fabric expansion device to solve the above problems. Utility Model Content
