[0002] Nonwoven fabrics have many advantages such as softness, breathability, moisture resistance, and environmental friendliness, and are widely used in many fields such as medical and health care, clothing, packaging, and agriculture. As the performance requirements of various industries continue to increase, plain nonwoven fabrics often cannot meet specific application needs. Coating technology, as an effective modification method, can further improve the waterproof, barrier, and wear-resistant properties of nonwoven fabrics by coating a thin film on the surface of the nonwoven fabric, thus expanding its application range.

[0003] However, in the existing composite nonwoven fabric thermal rolling lamination equipment, the nonwoven fabric is prone to lateral displacement during the transmission process, which makes it difficult to accurately laminate with the film. The laminated product is prone to uneven film coverage, affecting the appearance and quality of the product. Utility Model Content

[0010] Furthermore, the adjustment assembly includes two rectangular support plates fixedly connected to the top of the workbench, and a bidirectional threaded rod rotatably connected between the two rectangular support plates. The rear side of the bidirectional threaded rod passes through the rectangular support plate located on the rear side. Two guide frames are threadedly connected to the outer wall of the bidirectional threaded rod.

[0016] This utility model has the following beneficial effects:

[0017] 1. By setting up a guide section, when it is necessary to guide the raw materials, motor one can be started according to the width of the raw materials. Motor one drives the guide frame to rotate. At this time, the two guide frames will move closer or further apart under the restriction of slide rod one until the distance between the two guide frames is adapted to the width of the raw materials. During adjustment, due to the limitation of spring force, the position of support frame two will not change. Then, the two raw materials are pulled to pass through the two guide rollers, two guide frames and two hot rolling rollers, and are wound on the take-up roller. This can ensure that the non-woven fabric is always in the correct position during the transmission process, effectively avoiding its lateral position deviation, providing the prerequisite for accurate lamination of non-woven fabric and film, thereby improving the quality and consistency of the composite product, avoiding uneven film coverage, ensuring the appearance and quality of the product, and the adjustable distance between the guide frames enhances the versatility and flexibility of the device, improving the use value and economic benefits of the device.

[0018] 2. By setting up a preheating section, the heating coil can be heated before the raw material is hot rolled. The heat generated during heating will be conducted onto the heat-conducting plate. Then, motor two will be started, and motor two will drive the fan to rotate through shaft two, blowing the heat on the heat-conducting plate onto the non-woven fabric. This can achieve uniform preheating of the non-woven fabric, so that the non-woven fabric reaches a suitable temperature before entering the hot rolling process. This helps to improve the effect of hot rolling and coating, so that the non-woven fabric and the film can be better bonded, enhancing the bonding force between the two and reducing the occurrence of problems such as bubbles and film delamination.

[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
