Among them, resin and fiber are the basis of composite material composition, and the quality of prepreg directly affects the performance of composite materials. Prepreg contains about 35% resin. It has the advantages of uniform thickness, high strength characteristics, good repeatability, etc. It can reduce the curing time and make the processed parts have better appearance.

[0003] The production process of hot melt method prepreg includes resin heating and melting, resin coating and resin pre-impregnated fiber.

Finally, the heated and melted resin is transferred to the coating equipment. It takes at least 1-1.5 hours to heat the resin matrix using an oven, and the resin can meet the temperature requirements of the coating process. The resin matrix is in a high temperature state for a long time, which seriously affects the operation life of the prepreg resin and the prepreg. And the resin crushing, heating and transferring process needs a lot of manpower. Therefore, a hot melt method prepreg resin supply device is proposed. SUMMARY

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figure 1 and Figure 2 As shown, this utility model provides a technical solution for a hot-melt prepreg resin supply device, including a base 1, a caster wheel 2 at the bottom of the base 1, a protective shell 3 fixedly installed at one edge of the base 1, a heater 4 fixedly installed on the base 1, a supply mechanism 5 connected to the heater 4, and a crushing mechanism 6 on the protective shell 3. The crushing mechanism 6 can crush resin particles, and through the cooperation of the supply mechanism 5 and the heater 4, the resin powder can be rapidly melted to achieve a continuous supply of molten resin.

[0022] like Figure 2 and Figure 3 As shown, the supply mechanism 5 includes a supply pipe 501 fixedly installed in the heater 4 and a drive motor 507 fixedly installed in the equipment base 1. A material extrusion screw 502 is rotatably installed in the supply pipe 501. Temperature control switches 503 are installed at intervals on the supply pipe 501. A drive shaft 505 is fixedly installed at the output end of the drive motor 507. A first reducer 508 is provided between the drive shaft 505 and the material extrusion screw 502. An output shaft 506 is provided on the first reducer 508 and is fixedly installed on one end of the material extrusion screw 502. A feed inlet 504 is provided on the supply pipe 501. A detection port is opened on the supply pipe 501. The temperature control switches 503 are installed on the supply pipe 501 through the detection port.

[0023] Specifically, when the resin powder enters the supply pipe 501, it is subjected to the rotational force of the extrusion screw 502, causing the resin powder to move forward along the supply pipe 501. During this forward movement, the heater 4 can be activated, rapidly heating the resin powder. This heating process melts the resin powder, thus achieving a continuous supply of molten resin. Furthermore, the heater 4 is controlled by a temperature control switch 503 to ensure that the temperature within the supply pipe 501 remains near the resin's melting point. This temperature control prevents resin decomposition during heating, ensuring resin quality and the stability of the supply process.

[0024] like Figure 2 and Figure 4 As shown, the crushing mechanism 6 includes a crusher body 607 fixedly installed on the feed inlet 504. A feed hopper 601 is fixedly installed on the upper end of the crusher body 607. A movable shaft 604 is rotatably installed on the crusher body 607. A crushing roller 602 and a synchronous gear 603 are fixedly installed on the movable shaft 604, and the synchronous gears 603 on the movable shaft 604 mesh together. A second reducer 605 is provided between the movable shaft 604 and the drive shaft 505. Helical gears 606 are provided on the drive shaft 505, the first reducer 508, and the second reducer 605, and the helical gears 606 mesh together in pairs. A mounting bracket is provided inside the protective housing 3. The first reducer 508 and the second reducer 605 are both fixed inside the protective housing 3 by the mounting bracket.

[0025] Specifically, after the resin granules are poured into the feed hopper 601, the drive motor 507 can be started. Once the drive motor 507 is started, it will begin to drive the drive shaft 505 to rotate. Subsequently, after being reduced in speed by the second reducer 605, the drive shaft 505 will continue to drive the movable shaft 604 to rotate. Under the coordinated action of the synchronous gear 603, the movable shaft 604 will further drive the crushing roller 602 to rotate within the crusher body 607. This series of mechanical actions causes the resin granules to be crushed into fine powder under the action of the crushing roller 602, thereby significantly improving the speed at which the resin melts when heated.

[0026] Working principle: First, resin granules are poured into the feed hopper 601. After the granules are poured in, the drive motor 507 is started. Starting the drive motor 507 will drive the drive shaft 505 to rotate. After being reduced in speed by the first reducer 508 and the second reducer 605, the drive shaft 505 will drive the movable shaft 604 and the extrusion screw 502 to rotate. Under the action of the synchronous gear 603, the movable shaft 604 will drive the crushing roller 602 to rotate within the crusher body 607, thereby crushing the resin granules into powder and increasing the speed at which the resin melts upon heating. After the resin particles are crushed into powder, they enter the supply pipe 501 through the feed port 504. The resin powder entering the supply pipe 501 will move forward along the supply pipe 501 under the rotation of the extrusion screw 502. When the resin powder moves forward along the supply pipe 501, the heater 4 can be activated to heat the resin powder and make the resin powder melt rapidly, so as to realize the continuous supply of molten resin. The heater 4 is controlled by the temperature control switch 503 to keep the temperature in the supply pipe 501 near the melting point of the resin and prevent the resin from decomposing due to heat.
