Description

Technical Field

[0001] This utility model relates to the field of leveling equipment technology, specifically a leveling device for nonwoven fabric production. Background Technology

[0002] Non-woven fabric, also known as nonwoven cloth, needle-punched cotton, needle-punched non-woven fabric, etc., can be used in various industries, such as sound insulation, heat insulation, electric heating elements, masks and clothing. In the production process of non-woven fabric, a leveling device is needed to smooth it out, requiring leveling equipment for non-woven fabric production.

[0003] For example, Chinese patent CN221645333U discloses a leveling device for producing nonwoven fabrics, specifically relating to the technical field of nonwoven fabric production devices. It includes an operating table and fabric rollers. Two sets of mounting seats are provided at the top of one end of the operating table, with a pressure plate between the two sets of mounting seats. Two sets of horizontal plates are provided on one side of each mounting seat, and several sets of pressure rollers are provided at the bottom of each set of horizontal plates. Adjustment components are provided at the connection points between the pressure plate and the mounting seats, and between the horizontal plates and the operating table. Two sets of vertical plates are provided at the top of the other end of the operating table, with traction components provided on one side and inside each vertical plate. This invention not only enables the device to level nonwoven fabrics of different thicknesses but also allows for automatic traction of the leveled nonwoven fabric, effectively reducing the labor intensity of workers. It also makes the installation and disassembly of the fabric rollers more convenient and faster.

[0004] Although the aforementioned patent enables the device to flatten nonwoven fabrics of different thicknesses and to automatically pull the flattened nonwoven fabrics, effectively reducing the labor intensity of workers, the flattening plate in the patent relies solely on physical pressure to flatten high-strength nonwoven fabrics, which may not be sufficient to achieve the desired effect. This makes the flattening device functionally limited and reduces its practicality. Utility Model Content
