Description

Technical Field

[0001] The utility model relates to the technical field of embossing devices, in particular to a melt-blown nonwoven fabric embossing device. Background Art

[0002] Non-woven fabrics, also known as non-woven fabrics, are made of directional or random fibers. They are called cloth because they have the appearance and certain properties of cloth. Non-woven fabrics are moisture-proof, breathable, flexible, lightweight, non-combustible, easy to decompose, non-toxic and non-irritating, colorful, low-priced and recyclable. For example, they are mostly made of polypropylene pellets as raw materials, and are produced by a continuous one-step process of high-temperature melting, spinning, laying and hot pressing. With the development of the times and technology, the advancement of science and technology has also promoted the technological progress of non-woven fabric punching and embossing equipment.

[0003] For example, a non-woven fabric embossing device with publication number CN212128562U includes a main body, a base, a winding roller, a bottom shaft, a pressure roller, a connecting shaft and a platform. The bottom end of the main body is fixedly connected to the base, the winding roller is embedded in the inner side of the main body, the pressure roller is embedded in the inner bottom end of the main body, the two ends of the pressure roller are connected to the bottom shaft, the connecting shaft is fixedly connected to the two ends of the winding roller, the platform is located at the bottom of the main body, and the inner side of the main body is fixedly connected to the top plate. The arc-shaped pressing plate can stabilize the force when in contact with the cloth, and at the same time remove foreign matter on the surface of the cloth, and the protruding setting can effectively flatten the cloth, which is beneficial to the subsequent embossing steps. The wind tube located below the pressure roller can effectively cool the embossed cloth, and the flip setting with the connecting bracket allows the wind tube to cool the cloth at multiple angles.

[0004] In practical applications, the above technical solution cannot adjust the gap between the two rollers according to the thickness of the cloth, resulting in different pressures on cloths of different thicknesses, affecting the effect of punching and embossing.

[0005] Therefore, it is necessary to invent a meltblown nonwoven embossing device to solve the above problems. Utility Model Content
