Description

Technical Field

[0001] This utility model relates to the field of material processing and molding technology, and in particular to a device for simultaneous molding of melamine flame-retardant coating and polyurethane foam. Background Technology

[0002] In the application of polyurethane foam materials, flame-retardant treatment is usually required on their surface to meet fire safety requirements. The traditional production method involves first completing the polyurethane foam molding, and then applying a melamine flame-retardant coating through spraying, impregnation, or other methods. This step-by-step operation has many drawbacks. Step-by-step operation requires multiple workpiece transfers, increasing production time and costs. The traditional process has a longer production cycle than the simultaneous molding process, making it difficult to meet the needs of large-scale production. Due to the step-by-step operation, the coating does not bond tightly to the surface of the foam material, and during use, the coating is prone to peeling and cracking, affecting the flame-retardant effect and service life of the material. Therefore, this application proposes a device for simultaneous molding of melamine flame-retardant coating and polyurethane foam. Utility Model Content

[0003] The purpose of this invention is to address the problem in the prior art where the step-by-step operation results in insufficient bonding between the coating and the surface of the foamed material, and to propose a device for simultaneous molding of melamine flame-retardant coating and polyurethane foam.

[0004] The technical solution of this utility model: a melamine flame retardant coating and polyurethane foam synchronous molding device, including a raw material mixing tank and a synchronous molding mechanism disposed on one side of the raw material mixing tank. The synchronous molding mechanism includes a polyurethane foaming chamber located on one side of the raw material mixing tank. A support is fixedly connected to the outer wall of the polyurethane foaming chamber, and a coating box is fixedly connected to the top of the support.

[0005] The inner wall of the polyurethane foam chamber is provided with a foaming structure;

[0006] The outer wall of the paint tank is equipped with a paint spraying structure.

[0007] Optionally, the foaming structure includes a hydraulic pump fixed to one side of the outer wall of the polyurethane foaming chamber, a hydraulic rod slidably connected to the output end of the hydraulic pump, and multiple foaming meshes fixedly connected to the inner wall of the polyurethane foaming chamber, with a transmission port fixedly connected to the end of the polyurethane foaming chamber away from the hydraulic pump.

[0008] Optionally, a connecting pipe is fixedly connected to one side of the outer wall of the polyurethane foaming chamber, and a conveying pump is fixedly connected to the end of the connecting pipe away from the polyurethane foaming chamber. A transmission pipe is fixedly connected to the input end of the conveying pump, and the outer surface of the transmission pipe passes through the raw material mixing tank.

[0009] Optionally, the paint spraying structure includes a stirring mechanism fixed to the inner wall of the paint tank, and a paint inlet is fixedly connected to one side of the top of the paint tank.

[0010] Optionally, paint transfer pipes are fixedly connected to both sides of the outer wall of the paint tank, and a diversion box is fixedly connected to the end of the two paint transfer pipes away from the paint tank.

[0011] Optionally, the bottom end of the diversion box is fixedly connected to multiple rotating sections, and the bottom end of the multiple rotating sections is fixedly connected to a transmission nozzle.

[0012] Optionally, an inner tank is fixedly connected to the inner wall of the raw material mixing tank, and multiple heating coils are fixedly connected to the outer wall of the inner tank.

The mixing and heating of raw materials are achieved through an internal drive motor, mixing rod, inner tank, and heating coil. The melamine flame-retardant coating is sprayed through a synchronous molding mechanism including a polyurethane foaming chamber and its internal foaming structure, as well as a coating box and coating spraying structure. All parts work together to achieve synchronous molding of the melamine flame-retardant coating and polyurethane foam, reducing intermediate links and workpiece transfer time, allowing the melamine flame-retardant coating to better penetrate and adhere to the surface of the polyurethane foam material.

The raw materials are efficiently stirred and mixed by the drive motor 2 fixedly connected to the top of the raw material mixing tank 1 and the mixing rod 4 connected to its output end. Under the drive of the drive motor 2, the mixing rod 4 ensures that the raw materials of different formulations are mixed evenly. The inner tank 5 fixedly connected to the inner wall of the raw material mixing tank 1 and the multiple heating coils 6 wrapped around the outer wall of the inner tank 5 can accurately heat the raw materials to reach a suitable reaction temperature.

[0028] As one implementation method, such as Figure 2 , Figure 3 and Figure 4As shown, the inner wall of the polyurethane foaming chamber 10 is provided with a foaming structure. The foaming structure includes a hydraulic pump 11 fixed to one side of the outer wall of the polyurethane foaming chamber 10. A hydraulic rod 12 is slidably connected to the output end of the hydraulic pump 11. Multiple foaming meshes 13 are fixedly connected to the inner wall of the polyurethane foaming chamber 10. A transmission port 15 is fixedly connected to the end of the polyurethane foaming chamber 10 away from the hydraulic pump 11.

A hydraulic pump 11 is fixed to one side of the outer wall of the polyurethane foaming chamber 10. The hydraulic rod 12 pushes the polyurethane raw material to flow in the chamber. Multiple foaming meshes 13 are fixedly connected to the inner wall of the polyurethane foaming chamber 10 to promote the foaming reaction and make the bubbles uniform and dense. The transmission port 15 at the end of the polyurethane foaming chamber 10 away from the hydraulic pump 11 is used to output the molded polyurethane foam material. The connecting pipe 9, the delivery pump 8, and the transmission pipe 7 form a raw material delivery channel. The delivery pump 8 stably delivers the polyurethane raw material in the raw material mixing tank 1 to the polyurethane foaming chamber 10.
