Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric production technology, specifically to a nonwoven fabric winding 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., is made of polyester fiber, polyester fiber and other materials and is made through needle punching process. It can be used in different industries, such as sound insulation, heat insulation, electric heating element, mask, clothing, medical, filling material, etc. For industries with high requirements for breathability, holes are punched in the fabric to make porous non-woven fabric.

[0003] To solve the problem of nonwoven fabric entanglement, the existing technology is to switch between wrapping packaging methods, which can save the cost of purchasing two types of equipment and make the production work more flexible. However, there is still a situation where the nonwoven fabric cannot be tensioned during wrapping, which leads to the problem of the nonwoven fabric unraveling during transportation.

[0004] For example, Chinese patent CN221759039U discloses a nonwoven fabric winding device for automotive nonwoven fabric production, including a base plate. A winding unit, a pressing unit, and a tensioning unit are provided on the top surface of the base plate. The tensioning unit includes a connecting frame, which is fixedly connected to the top surface of the base plate. A support rod is provided through the top surface of the connecting frame. A pressing wheel is fixedly connected to one end of the support rod. A spring is fixedly connected to the top surface of the pressing wheel, which is located on the outside of the support rod. A fixing block is fixedly connected to the inside of the connecting frame, and a sliding rod is fixedly connected to the top surface of the fixing block. This invention, through the action of the support rod and auxiliary rollers, enables the pressing wheels to achieve a tight fit between the nonwoven fabric during movement, thus preventing wrinkles in the nonwoven fabric before winding.

[0005] However, nonwoven fabrics may shift laterally during the winding process, and ordinary circular winding rollers may slip, resulting in poor winding effect. Utility Model Content

[0006] The purpose of this utility model is to provide a nonwoven fabric winding device for nonwoven fabric production, so as to solve the problems mentioned in the background art, such as the possibility of lateral displacement of nonwoven fabric during winding, and the possibility of slippage of ordinary circular winding rollers, resulting in poor winding effect.
