[0001] This utility model relates to the field of composite material spiral component molding technology, specifically a composite material spiral pultrusion molding device. Background Technology

[0002] Pultrusion molding originated in the United States in 1948 and matured in the late 1950s. This process is highly automated and efficient; it produces no waste material, and the products generally do not require post-processing, saving labor, materials, and energy. It is best suited for producing profiles with specific cross-sectional shapes such as I-beams, channel profiles, square profiles, and round profiles, producing products with good quality stability, repeatability, and the ability to be cut to any length.

[0003] According to the patent application published on the Internet, a spiral pultrusion molding device for composite materials (authorization announcement number: CN116476412B) describes "This invention relates to a spiral pultrusion molding device for composite materials: including a spiral composite material molding assembly, a fiber impregnator for conveying impregnated fiber bundles to the spiral composite material molding assembly, and a clamping and fixing device for clamping the molded spiral composite material output from the spiral composite material molding assembly; wherein, the spiral composite material molding assembly includes a female mold, the female mold has a transverse through-hole, a male mold is tightly inserted into the through-hole, the outer surface of the male mold has a spiral groove arranged along its length, a heating mechanism is provided in the female mold, one end of the male mold extends out of the female mold and is connected to a rotating mechanism, the rotating mechanism is fixed on a linear motion mechanism; the above design solves the problem of cumbersome and complex continuous production process of spiral composite material products."

[0004] Regarding the above description, the applicant believes the following issues exist:

The fiber guide head assists in the orderly transport of fibers, allowing the resin glue to be sprayed evenly.

[0011] Preferably, the number of stirring paddles is three, and they are arranged in a circumferential array around the central axis of the stirring rod, which facilitates continuous stirring of the resin in the storage tank and makes the resin solution more uniform.

[0012] Preferably, the number of nozzles is three, and they are arranged in a circumferential array around the central axis inside the fiber bundler, which facilitates impregnation of the fiber bundle from different angles and reduces the possibility of insufficient or excessive impregnation in certain areas.

[0013] Preferably, there are ten fiber guide heads, which are arranged in a circumferential array around the central axis of the rotating wheel, so that the external yarn frame can be used to concentrate the fibers into fiber bundles.

A fixing frame 2213 is fixedly installed on the back of the vertical plate 2212 near the bottom. A fourth motor 2214 is fixedly installed on the back of the fixing frame 2213. A gear 2215 is fixedly installed at the output end of the fourth motor 2214. A rotating wheel 2216 is movably installed inside the vertical plate 2212. The rotating wheel 2216 meshes with the gear 2215. A fiber guide head 2217 is fixedly installed on the front of the rotating wheel 2216, which facilitates the fourth motor 2214 to drive the gear 2215 and the rotating wheel 2216. The fiber guide head 2217 assists in the orderly conveying of fibers, so that the resin glue can be sprayed evenly.

[0033] Furthermore, there are three agitators 2218, which are arranged in a circular array around the central axis of the agitator 228 to facilitate continuous agitation of the resin in the storage tank 226, making the resin solution more uniform.

[0034] Furthermore, there are three nozzles 223, which are arranged in a circumferential array around the central axis inside the fiber bundler 222, which facilitates impregnation of the fiber bundle from different angles and reduces the possibility of insufficient or excessive impregnation in certain areas.

[0035] Furthermore, there are ten fiber guide heads 2217, which are arranged in a circumferential array around the central axis of the rotating wheel 2216, so as to facilitate the auxiliary external yarn frame to concentrate the fibers into fiber bundles. Example

[0036] Please see Figure 5-6Furthermore, in conjunction with Embodiment 1, the cooling group 3 includes an air pump 31, which is fixedly installed at the bottom of the table 1. A collar 32 is fixedly installed at the top of the table 1. An air duct 33 is opened inside the collar 32. The output end of the air pump 31 is fixedly installed at the bottom of the air duct 33 through a connecting pipe. An air outlet 34 is fixedly installed at the top of the collar 32, which facilitates rapid cooling and demolding of the material after it has been shaped at high temperature in the female mold 218, so as to carry out the next operation.

[0037] Furthermore, the number of air outlets 34 is three, and they are installed in a circumferential array around the central axis inside the collar 32, which facilitates uniform cooling of the spiral composite material product and avoids product deformation due to uneven local cooling.

[0038] In actual operation, when this device is used, the first motor 211 is started, which drives the first threaded rod 212 to rotate, causing the movable block 213 to slide within the matching groove of the table 1. This moves the sliding plate 214, the fixed seat 215, and the male mold 217 to the appropriate position. Then, the second motor 216 is turned on, and the male mold 217 begins to rotate. At the same time, the third motor 227 drives the stirring rod 228 and the three circumferentially arranged stirring paddles 2218 to continuously stir the resin liquid in the glue storage tank 226, ensuring... The resin solution is kept in a uniform state. After being stirred evenly, the delivery pump 225 is started, sending the resin solution through the delivery pipe 224 to the fiber bundler 222. The fiber raw material is drawn out from the external feeding device through the fiber guide head 2217. The fourth motor 2214 drives the gear 2215 to rotate, and the rotating wheel 2216 meshing with it rotates synchronously. With the assistance of the fiber guide head 2217, the fiber enters the fiber bundler 222 and is gathered and collected. At this time, the three nozzles 223 arranged in a circular array inside the fiber bundler 222 spray the resin solution... The resin is evenly sprayed onto the fiber bundles to complete the impregnation. The impregnated fiber bundles are then transported in an orderly manner to the rotating male mold 217. When the spiral groove of the male mold 217, which is near the movable block 213, is fully inserted into the female mold 218, the operator inputs the preset rotation speed and lateral movement speed parameters on the control panel. The male mold 217 then rotates clockwise according to the set parameters and moves forward into the female mold 218. The heating mechanism in the female mold 218 executes the corresponding heating program according to the type of resin impregnated in the fiber bundles. During the rotation and advancement of the male mold 217, the impregnated fiber bundles wrapped in its spiral grooves enter the heating area of ​​the female mold 218. The resin undergoes a chemical cross-linking reaction when heated, gradually solidifying to form a spiral composite material. After solidification is complete, the male mold 217 continues to maintain the predetermined speed. At this time, the formed spiral composite material enters the cooling group 3. The air pump 31 is started, pressing air into the air duct 33 in the collar 32, and then evenly discharged through the three circumferentially distributed air outlets 34, providing rapid and uniform cooling to the composite material. After cooling, the composite material can undergo subsequent processing steps such as collection and cutting, allowing the equipment to continue with the next round of pultrusion molding.

[0039] The female mold is equipped with a heating mechanism, and the male mold surface is provided with a spiral groove.
