Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric composite technology, specifically to a solvent-free nonwoven fabric composite device. Background Technology

[0002] Non-woven fabric, also known as non-woven cloth, is composed of oriented or randomly arranged fibers. It is called cloth because it resembles the appearance and some properties of fabric. Non-woven fabrics are characterized by moisture resistance, breathability, flexibility, light weight, non-flammability, easy decomposition, non-toxicity, non-irritation, rich colors, low price, and recyclability. They are often produced using polypropylene (PP) granules as raw material through a continuous one-step process of high-temperature melting, spinning, laying, and hot-pressing.

[0003] A search of existing published patents revealed that, according to patent number CN201922205761.1, entitled "A Composite Machine for Producing Nonwoven Fabrics," the machine includes a composite machine body, a tension roller, a guide roller, a guide roller, a motor, a first electric heating roller, and a second electric heating roller. The composite machine body has a fabric outlet at the center of its right end face, a first fabric inlet at the upper right end face, and a second fabric inlet at the lower right end face. The tension roller, guide roller, and guide roller are arranged in a triangular pattern. The first electric heating roller is rotatably connected to the interior of the composite machine body via a first transmission shaft. The second electric heating roller is rotatably connected to the interior of the composite machine body in parallel with the first electric heating roller via a second transmission shaft. The first transmission shaft is connected to the output end of the motor via a first transmission belt, and the second transmission shaft is connected to the output end of the motor via a second transmission belt. This invention utilizes the synchronous rotation of two electric heating rollers to ensure the synchronicity of the nonwoven fabric and maintain its tension, preventing wrinkles from forming.

[0004] However, the above-mentioned device has the same spacing between the hot pressing mechanisms during use, which makes it inconvenient to adjust the coating thickness of the solvent-free adhesive according to different specifications of nonwoven fabrics. Its applicability is limited, and there is room for improvement. Utility Model Content
