Description

Technical Field

[0001] The utility model relates to the technical field of automobile non-woven fabric production, in particular to a pressing mechanism for automobile non-woven fabric production. Background Art

[0002] Automotive non-woven fabrics are a new generation of environmentally friendly materials that are moisture-proof, breathable, flexible, lightweight, flame-retardant, heat-insulating, non-toxic, odorless, and non-irritating. Non-woven fabrics are widely used in automobiles, such as car trunks, car seat cushions, car ceiling sound insulation, etc. In the production process of automotive non-woven fabrics, the materials need to be pressed, and non-woven fabric pressing machines came into being, which can automatically press the materials. Hot pressing is often used to press multiple layers of non-woven fabrics; that is, by adding fibrous hot-melt adhesive materials to adjacent fiber mesh fabrics, the fiber mesh fabrics are then heated, melted, and cooled to reinforce them into non-woven fabrics. After searching: A pressing equipment for the production of bamboo fiber non-woven fabrics with the authorization publication number CN208899198U includes a plurality of support rods, a workbench is welded to the upper ends of the plurality of support rods, connecting rods are welded between the support rods, and the connecting rods are placed horizontally, a plurality of rollers are installed on the upper end of the workbench, and fixed blocks are sleeved in the gaps at both ends of the rollers, and the fixed blocks are welded to both sides of the upper end of the workbench.

[0003] However, the above-mentioned pressing mechanism for the production of automotive non-woven fabrics still has some shortcomings. Although the non-woven fabric raw materials can be limited front and back to avoid deviation, it is inconvenient to quickly and efficiently cool the pressed automotive non-woven fabrics after hot pressing due to the use of hot pressing. The automotive non-woven fabrics need to be directly rolled up, which can easily cause thermal adhesion between the automotive non-woven fabrics. Therefore, we propose a pressing mechanism for the production of automotive non-woven fabrics to solve the above problems. Utility Model Content
