Description

Technical Field

[0001] The present application relates to the technical field of grinding equipment, and in particular to an automatic pressure-regulating rolling device. Background Art

[0002] Nonwoven fabric is a kind of fabric that does not require spinning and weaving. It is formed by directional or random arrangement of textile short fibers or filaments to form a fiber mesh structure, and then reinforced by mechanical, thermal bonding or chemical methods. It is a new type of fiber product with soft, breathable and planar structure formed directly from polymer slices, short fibers or filaments through various fiber mesh forming methods and consolidation technologies. The formed nonwoven fabric needs to be collected in rolls, but because the nonwoven fabric itself has a certain elasticity and production stress, in the process of rolling, it is necessary to apply appropriate force to the nonwoven fabric to make the nonwoven fabric neatly rolled. If the force applied is too large, it will damage the structure of the nonwoven fabric. If the force applied is too small, the nonwoven fabric after rolling will be very messy, which is not conducive to subsequent processing and use. Utility Model Content
