Technical Field

[0001] The utility model relates to the technical field of fabric production, and more specifically, to a laminating device for producing automotive composite fabrics. Background Art

[0002] With the continuous update and development of the automotive industry, the industry has higher and higher requirements for the lamination of automotive interior fabrics, and also puts forward higher requirements for production processes. Currently, flame lamination and glue lamination are mainly used in the automotive interior lamination industry. Among them, PUR moisture-reactive hot melt adhesive lamination is the mainstream in glue lamination, which has advantages such as low odor and good lamination fastness. However, in the actual production process, after PUR glue is laminated between fabric or PVC leather and sponge, it needs to react and cure on a large roll for a certain period of time. After curing, the composite product is prone to surface orange peel and pit phenomena, resulting in unqualified or scrapped composite products, seriously affecting production quality control.

[0003] Therefore, it is necessary to provide a laminating device for producing automotive composite fabrics that does not require reaction curing. Summary of the Utility Model

[0024] The present utility model will now be described in further detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present utility model in a schematic manner, and thus only showing the components related to the present utility model.

[0025] Please refer to Figure 1 and in combination with Figures 2 to 3 , Figure 1 is a perspective view of the optimal embodiment of a laminating device for producing automotive composite fabrics according to the present utility model; Figure 2 is a perspective view of the optimal embodiment of the pressing mechanism of the present utility model; Figure 3 is a schematic structural diagram of the composite process of the composite fabric of the present utility model. As Figures 1 to 3 shown, at least one embodiment provides a laminating device for producing automotive composite fabrics, including: an assembly frame 1, the assembly frame 1 is U-shaped, including two side plates and a bottom plate. From one side to the other side of the assembly frame 1, a surface layer conveying mechanism 2, a sponge conveying mechanism 4, a pressing mechanism 5 and a winding mechanism 6 are arranged in sequence. The surface layer conveying mechanism 2, the sponge conveying mechanism 4, the glue applicator head 3, the pressing mechanism 5 and the winding mechanism 6 are all arranged on the two side plates. The surface layer conveying mechanism 2 is used to convey the fabric body 7 and apply glue on the bonding surface of the fabric body. The sponge conveying mechanism 4 is used to convey the sponge body 8 to the bonding position with the fabric body 7. The pressing mechanism 5 is used to press the two fabrics together. The winding mechanism 6 is used to wind up the successfully laminated composite product. A glue applicator head 3 is installed on the assembly frame 1 above the surface layer conveying mechanism 2. A heat drying port 11 is fixed on the bottom surface of the assembly frame 1 between the surface layer conveying mechanism 2 and the pressing mechanism 5. The heat drying port 11 is arranged on the bottom plate and is communicated with an infrared heating device. The temperature of the heat drying port 11 is between 80 - 100 °C.

[0026] Please continue to refer to Figure 3 . As Figure 3 shown, the surface layer conveying mechanism 2 includes a glue application roller 21 and a back pressure roller 22, and the gap formed between the glue application roller 21 and the back pressure roller 22 is suitable for conveying the fabric body 7. The pressing mechanism 5 includes a lower pressing roller 51 and an upper pressing roller 52, and the gap formed between the lower pressing roller 51 and the upper pressing roller 52 is suitable for bonding the fabric body 7 and the sponge body 8 and outputting the composite fabric 9.

[0027] Please continue to refer to Figure 3 and in combination with Figure 4 , Figure 4 is a schematic structural diagram of the optimal embodiment of the glue application roller of the present utility model. As Figures 3 to 4As shown in the figure, a soft sleeve 23 is provided on the surface of the glue applicator roll 21, and a glue coating layer 25 is provided on the surface of the soft sleeve 23. The glue coating layer 25 is made of pp material, and the thickness of the glue coating layer 25 is 1 - 5 mm. A plurality of pits 24 are provided on the surface of the glue coating layer 25. The pits 24 are for storing glue inside. When being extruded on the bonding surface with the fabric body 7, the glue remains on the bonding surface and abuts against the smooth glue coating layer 25, so that a larger amount of glue can be coated. Moreover, the equidistant arrangement of the pits 24 is conducive to the flat pressing of the two layers of fabric. In addition, in order to facilitate the outflow of the melted glue, the glue head 3 includes a triangular prism-shaped outer shell, and one of the sharp corners of the outer shell faces the glue applicator roll 21. A glue spreading strip is provided at the bottom opening position of the triangular prism-shaped outer shell, and the glue spreading strip abuts against the glue coating layer 25. The triangular prism-shaped outer shell is communicated with a screw extruder. The screw extruder is filled with copolyester glue particles. The screw extruder turns the particles into a melted state by heating and sends them into the glue head 3, and then the glue is coated on the glue applicator roll 21 through the glue head 3.

[0028] Specifically, different from the conventional PUR moisture-reactive glue, the copolyester (COPES) glue particles of model HT-5105 are used in this embodiment; this glue can be melted by heating up and solidified by cooling down, without the need for a curing reaction process; when in use, the glue particles are melted at a high temperature by a screw extruder, and the melting temperature is 170 - 180 °C, and the melted glue is injected into the glue head 3; in the bonding process, the glue applicator roll 21 transfers the melted glue to the bonding surface of the fabric body 7 (such as fabric or PVC leather, etc.). During the transfer process, the raw materials and the glue on the bonding surface of the materials are heated and insulated for the second time by an infrared heating device. The insulation method is online real-time heating, and the heating temperature is 80 - 100 °C to ensure that the glue is in a melted state and maintains viscosity; the two layers of materials are quickly pressed together by the lower pressing roll 51 and the upper pressing roll 52. After pressing, the glue cools down naturally in the normal temperature environment, and then the two layers of materials are bonded together and can immediately enter the next process for winding; since the glue does not need to be cured throughout the process, the composite product does not need to be extruded for a long time on the roll, so problems such as orange peel will not occur.

[0029] In summary, by setting the glue head 3 with copolyester glue particle raw materials, the need for curing after glue spreading and pressing is eliminated, the curing steps are reduced, the production efficiency is improved, and problems such as orange peel and pits on the surface of the composite product are solved; the qualification rate of the composite product is improved; by setting the pits 24, the glue spreading uniformity is improved, the glue retention amount is increased, and the bonding firmness of the composite product is enhanced.

[0030] Based on the above-mentioned ideal embodiments of the present utility model as a revelation, through the above description, relevant staff can completely make various changes and modifications without departing from the technical idea of this utility model. The technical scope of this utility model is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
