Description

Strip material feeding structure Technical Field The utility model relates to the technical field of feeding equipment, in particular to a strip material feeding structure. Background The air spring is a common elastic element on an air suspension, is generally made of rubber, has good tightness and compressibility, and achieves a function similar to a spring by utilizing the compressibility of gas after compressed air is injected. In the air spring production process, the strip-shaped materials such as curtain cloth, films and the like are mostly supplied through a roller type feeding structure, and the roller type feeding structure is easy to have the condition that the materials deviate in the feeding process, so that a corresponding deviation correcting structure is arranged in the feeding structure, and the accurate supply of the materials is ensured. For example, in the text of CN106672672B, a belt-like material feeding device is described, an unwinding mechanism capable of sliding left and right is mounted on a feeding frame, and the position of the unwinding mechanism on the feeding frame is adjusted by driving an adjusting mechanism, so as to implement the deviation correcting operation of the material.
