Description

Technical Field

[0001] This utility model relates to the field of carbon material processing technology, specifically to a carbon fiber prepreg cooling mechanism. Background Technology

[0002] During the processing of carbon fiber prepreg, the resin needs to be heated to reduce its viscosity, making it easier to coat the carbon fiber surface evenly. After impregnation, the prepreg is at a high temperature. If it is not cooled in time, the resin will cure prematurely in subsequent processing, affecting the product's molding and performance. Therefore, cooling rollers are needed to cool it.

[0003] Currently, commonly used cooling rollers typically cool the prepreg fabric by filling the hollow roller with cold water, thereby lowering the roller surface temperature. However, this cooling method has drawbacks. The ambient temperature during processing is usually higher than the surface temperature of the cooling roller. When hot air comes into contact with the cold roller surface, the water vapor in the air condenses, forming condensate on the roller surface. Once this condensate transfers to the carbon fiber prepreg fabric, it increases the moisture content of the prepreg, leading to uneven curing and ultimately reducing the quality of the carbon fiber prepreg fabric. Summary of the Invention

[0004] The purpose of this invention is to provide a cooling mechanism for carbon fiber prepreg that can effectively remove condensate from the roller surface.

[0005] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is: a carbon fiber prepreg cooling mechanism, comprising a hollow roller body, the two ends of which are respectively connected to an inlet pipe and an outlet pipe, forming a rotational fit;

[0006] The surface of the roller body is provided with a plurality of long grooves that are uniformly arranged in a ring and extend along the length of the roller body. The long grooves extend from one end of the roller body to the other end of the roller body. It also includes a moisture-absorbing sponge, which includes a disc-shaped part and a plurality of strip-shaped parts that cooperate with the long grooves. The strip-shaped parts of the moisture-absorbing sponge are engaged in the long grooves, and the disc-shaped parts are located at one end of the roller body.

[0007] It also includes an extrusion plate installed on one side of the disc-shaped part, in contact with the disc-shaped part, for extruding condensate from inside the disc-shaped part.

[0008] Preferably, the extrusion plate is an arc-shaped plate.

[0009] Preferably, a water collection trough is provided below the disc-shaped portion, and a drain pipe is provided at the bottom of the water collection trough.

[0010] Preferably, the extrusion plate is mounted on the water collection tank via a support plate disposed on the side wall of the water collection tank; a rod is provided on the side of the extrusion plate facing away from the disc-shaped part, and a guide sleeve that cooperates with the rod is provided on the support plate; the rod is inserted into the guide sleeve and forms a sliding fit with the guide sleeve; a top pressure spring is also sleeved on the rod between the support plate and the extrusion plate, and the extrusion plate is pressed against the disc-shaped part by the top pressure spring.

[0011] Preferably, hollow roller shafts are provided at both ends of the roller body, and the water inlet pipe and water outlet pipe are connected to the roller shafts; the circumferential surface of the roller shaft is provided with an mounting section for connection with the bearing.

[0012] The beneficial effects of this invention are mainly reflected in its ability to quickly treat condensate on the surface of the cooling roller, preventing condensate from adversely affecting the prepreg workpiece being cooled. Specifically, during use, the roller body rotates and contacts the prepreg fabric through the roller surface (circumferential surface), achieving cooling of the prepreg fabric. Because the roller body has strip-shaped sections of absorbent sponge on its circumferential surface, it can quickly absorb condensate when it appears and conduct it to the disc-shaped section under capillary action. The extrusion plate located at the disc-shaped section continuously extrudes the disc-shaped section as the roller body rotates, thereby squeezing out the condensate and maintaining the continuous moisture absorption performance of the absorbent sponge.

[0015] Figure 3 This is a schematic diagram of the extrusion plate. Detailed Implementation

[0016] like Figure 1-3 As shown, a carbon fiber prepreg cooling mechanism is used to perform a secondary cooling treatment on the prepreg that has been initially cooled and shaped in a cold air box after impregnation. Figure 1As shown, it includes a hollow roller body 1, with its two ends connected to an inlet pipe 2 and an outlet pipe 3, respectively, forming a rotational fit. Cooling water enters and exits through the inlet pipe 2 and the outlet pipe 3, forming a cooling cycle. When the roller body 1 is large, a jacketed structure can be used internally, forming a cooling water channel between the inner and outer rollers to fully utilize the cooling effect of the internal cooling water; when the roller body 1 is small, the inner cavity of the roller body 1 is generally used directly as the cooling water channel. In this invention, hollow roller shafts 14 are typically provided at both ends of the roller body 1, and the inlet pipe 2 and the outlet pipe 3 are connected to the roller shafts 14. The circumferential surface of the roller shaft 14 is provided with a mounting section 15 for connection with bearings, and the roller body 1 is mounted on the frame through bearings and bearing seats.

[0017] Combination Figure 1 and 2 As shown, the surface of the roller body 1 is provided with a plurality of elongated grooves 4 evenly arranged in a ring shape, extending along the length direction of the roller body 1. The elongated grooves 4 extend from one end of the roller body 1 to the other end. It also includes a moisture-absorbing sponge, which comprises a disc-shaped portion 5 and a plurality of strip-shaped portions 6 that cooperate with the elongated grooves 4. The strip-shaped portions 6 of the moisture-absorbing sponge are engaged within the elongated grooves 4, and the disc-shaped portions 5 are located at one end of the roller body 1. The strip-shaped portions 6 are mainly used to absorb condensate on the roller surface, and the disc-shaped portions 5 are used to absorb the condensate from the strip-shaped portions 6 and also serve as a drainage area. It also includes an extrusion plate 7 installed on one side of the disc-shaped portions 5, in contact with the disc-shaped portions 5, for extruding condensate from within the disc-shaped portions 5, such as... Figure 3 As shown, the extrusion plate 7 can be an arc-shaped plate or other shapes that serve the same function.

[0018] During use, the roller 1 rotates and contacts the prepreg fabric through its surface (circumferential surface), thus cooling the prepreg fabric. Because the roller 1 has strip-shaped sections 6 for absorbing moisture (sponge-like structures), it can quickly absorb condensate when it appears and conduct it to the disc-shaped section 5 through capillary action. The extrusion plate 7 located at the disc-shaped section 5 continuously extrudes the condensate as the roller 1 rotates, thereby squeezing it out and maintaining the continuous moisture absorption performance of the sponge. To collect the extruded condensate, a water collection trough 8 is provided below the disc-shaped section 5, and a drain pipe 9 is installed at the bottom of the water collection trough 8.

[0019] Regarding the installation of the extrusion plate 7, it can be installed using a separate bracket, or it can be installed directly using the water collection tank 8. For example... Figure 1As shown, the extrusion plate 7 is mounted on the water collection tank 8 via a support plate 10 located on the side wall of the water collection tank 8. A rod 11 is provided on the side of the extrusion plate 7 facing away from the disc-shaped portion 5, and a guide sleeve 12 that cooperates with the rod 11 is provided on the support plate 10. The rod 11 is inserted into the guide sleeve 12 and forms a sliding fit with it. A top-pressure spring 13 is also sleeved on the rod 11 between the support plate 10 and the extrusion plate 7. The extrusion plate 7 is pressed against the disc-shaped portion 5 by the top-pressure spring 13 to maintain the extrusion force. Furthermore, when the pressure is too high, the compression of the top-pressure spring 13 allows the extrusion plate 7 to automatically retract, preventing overpressure when the water volume is large.
