Description

Technical Field

[0001] This utility model relates to the field of impregnation equipment technology, specifically to an impregnation equipment for double-layer fabrics. Background Technology

[0002] Currently, when using prepreg for lining, workers can only lay it layer by layer, not multiple layers simultaneously. This results in longer laying times, lower efficiency, and higher costs. Furthermore, wrinkles easily form during laying, causing more air to be trapped between the two layers of prepreg, which in turn increases the difficulty of the processing and molding. Using high-grammage fabrics carries the risk of insufficient resin impregnation and appearance defects due to overly large mesh sizes.

[0003] Therefore, how to provide a double-layer fabric impregnation device that can improve the efficiency of laying and prepreg production has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] The purpose of this invention is to design a double-layer fabric impregnation device, which is beneficial to improve the work efficiency of laying and prepreg production, and ensures that the two layers of prepreg are tightly bonded without wrinkles or bulges, and avoids problems such as insufficient impregnation and appearance defects caused by the prepreg being too thick.

[0005] To achieve the above objectives, this utility model provides a double-layer fabric impregnation device, comprising: a first fabric roller, a first adhesive film roller, a first roller wheel, a first release paper recovery roller, a second fabric roller, a second adhesive film roller, a second roller wheel, a second release paper recovery roller, and a PE film roller; a first fabric wound on the first fabric roller is composited with two layers of first adhesive film wound on the upper and lower sides of the first adhesive film roller, and impregnated by the first roller wheel; the first release paper recovery roller is used to peel off the release paper from the impregnated first composite layer; the second fabric wound on the second fabric roller is bonded to the first composite layer after the release paper has been peeled off, the second adhesive film wound on the second adhesive film roller is bonded to the second fabric, and impregnated by the second roller wheel; the second release paper recovery roller is used to peel off the release paper from the impregnated second composite layer, and the PE film wound on the PE film roller is bonded to the second composite layer after the release paper has been peeled off, forming a double-layer fabric.

[0006] Furthermore, it also includes a finished product take-up roller, through which the double-layer fabric is wound and stored.

[0007] Furthermore, the double-layer fabric includes a first fabric, a first adhesive film, a second fabric, a second adhesive film, and a PE film; the first adhesive film is attached to both the upper and lower sides of the first fabric, a release paper is attached below the lower first adhesive film, the second fabric is attached above the upper first adhesive film, the second adhesive film is attached above the second fabric, and the PE film is attached above the second adhesive film.

[0008] Furthermore, it also includes guide wheels, through which the first adhesive film, release paper, second adhesive film, and PE film are all guided.

[0009] The beneficial effects of this utility model are as follows:

[0010] This invention provides a double-layer fabric impregnation device, which is beneficial to improving the work efficiency of laying and prepreg production, and ensures that the two layers of prepreg are tightly bonded without wrinkles or bulges. It also avoids problems such as insufficient impregnation and appearance defects caused by the prepreg being too thick. Compared with single-layer fabric prepreg impregnation products, it also saves half of the release paper and half of the PE film. Attached Figure Description

[0020] This utility model also includes a finished product take-up roller 6, through which the double-layer fabric is wound and stored, thereby facilitating the collection of finished products.

[0021] refer to Figure 2The double-layer fabric includes a first fabric 11, a first adhesive film 12, a second fabric 13, a second adhesive film 14, and a PE film 15. The first adhesive film 12 is adhered to both the upper and lower sides of the first fabric 11. Release paper 16 is adhered below the lower first adhesive film 12, the second fabric 13 is adhered above the upper first adhesive film 12, the second adhesive film 14 is adhered above the second fabric 13, and the PE film 15 is adhered above the second adhesive film 14. The two fabric layers are sequentially laid on the adhesive film for impregnation, with an adhesive film tightly bonding the two fabric layers together, resulting in two tightly bonded prepreg layers. During prepreg laying, workers can lay two layers at once, doubling work efficiency and reducing wrinkles and bulges, avoiding insufficient impregnation and appearance defects caused by an excessively thick single fabric layer. Furthermore, two layers of prepreg can be produced simultaneously during prepreg production, doubling production efficiency.
