Description

Technical Field

[0001] This application relates to the field of cooling equipment technology, and more specifically, to a cooling device for prepreg resin. Background Technology

[0002] After the hot-melt prepreg resin is mixed in the mixing tank, it is still in a flowing state in order to be smoothly extruded from the tank and bagged for storage. The temperature of the hot-melt prepreg resin is usually above 60°C. The discharge temperature of bismaleimide, phenolic, cyanate ester resins and some high-viscosity resin systems is even higher. Each batch of resin usually takes more than 30 minutes to complete the discharge.

[0003] The traditional method is to seal the bagged resin and place it in a pallet. After all the resin is packaged, it is transported to a cold storage for cooling and storage.

[0004] The following problems exist in the processing of prepreg resin: Before being sent to the cold storage for cooling, the prepreg resin is in a high-temperature state, which will affect the latent properties of the prepreg resin and have an adverse effect on subsequent storage and transportation as well as the shelf life of the final prepreg product; if the high-temperature prepreg resin is directly put into the cold storage, the large temperature difference between the prepreg resin and the cold storage will affect the performance of the prepreg resin. Summary of the Invention

[0005] To address the aforementioned problems, the technical solution adopted in this application is:

[0006] A cooling device for prepreg resin includes a cooling box, which includes a cooling plate, an inlet and an outlet. The cooling plate is located inside the cooling box, the inlet is located at the front end of the cooling plate, and the outlet is located at the rear end of the cooling plate. The cooling plate has multiple cooling zones and heat insulation plates, which are located between adjacent cooling zones. The temperature of the cooling zones decreases sequentially from front to back.

[0007] Preferably, the upper surface of the cooling plate is horizontally arranged, and the upper surface of the cooling zone and the upper surface of the heat insulation plate are smoothly connected.

[0008] Preferably, the cooling plate is provided with a first cooling zone, a second cooling zone, a third cooling zone, a first heat insulation plate, and a second heat insulation plate, with the first heat insulation plate disposed between the first cooling zone and the second cooling zone, and the second heat insulation plate disposed between the second cooling zone and the third cooling zone.

[0009] Preferably, the cooling zone includes a cooling pipe, an inlet connector, and a return connector. The inlet connector and the return connector are respectively located at both ends of the cooling pipe and are both connected to the cooling pipe. The cooling pipe is coiled within the cooling zone.

[0010] Preferably, both the inlet and outlet water connectors are located outside the cooling tank and on the same side of the cooling tank.

[0011] Preferably, the cooling box includes multiple cooling plates, which are distributed in layers and parallel to each other.

[0012] Preferably, the cooling box includes a first cooling plate and a second cooling plate, with the first cooling plate positioned directly above the second cooling plate.

[0013] Preferably, the cooling plate further includes a front extension and a rear extension, the front extension being located at the front end of the cooling plate and the rear extension being located at the rear end of the cooling plate; both the front extension and the rear extension extend outside the cooling box.

[0014] Preferably, the cooling device further includes a tray made of a material with excellent thermal conductivity, and a prepreg resin is disposed inside the tray; the size of the cooling zone is adapted to the size of the tray.

[0015] The beneficial effects of this application are as follows: the prepreg resin to be cooled is placed in a storage container and pushed into the cooling box sequentially from the inlet; the storage container is placed on the cooling plate and can slide along the cooling plate, and subsequent storage containers will push the storage containers behind them to move backward along the upper surface of the cooling plate; the storage containers move backward along the cooling plate, passing through different cooling zones in sequence for cooling; the temperature of the cooling zones decreases sequentially from front to back, and no excessive temperature difference is formed between the prepreg resin and the cooling plate, gradually cooling down, which can ensure the cooling effect and avoid excessive temperature difference affecting the performance of the prepreg resin; finally, the prepreg resin that has slid to the rear end of the cooling plate and completed cooling is taken out from the outlet of the cooling box, which is convenient to operate; the inlet is located at the front end of the cooling plate and the outlet is located at the rear end of the cooling plate, which can ensure that the prepreg resin is first-in-first-out and is less likely to be mistaken when taking it out.

[0024] The present application provides a cooling device for prepreg resin.

[0025] like Figures 1 to 3 As shown, a cooling device for prepreg resin includes a cooling box 1. The cooling box 1 includes a cooling plate 11, an inlet 12, and an outlet 13. The cooling plate 11 is disposed inside the cooling box 1, the inlet 12 is disposed at the front end of the cooling plate 11, and the outlet 13 is disposed at the rear end of the cooling plate 11. The cooling plate 11 is provided with multiple cooling zones 111 and heat insulation plates 112. The heat insulation plates 112 are disposed between adjacent cooling zones 111, and the temperature of the cooling zones 111 decreases sequentially from front to back.

[0026] The prepreg resin to be cooled is placed in a storage container and pushed into the cooling box 1 through the inlet 12. The storage container is placed on the cooling plate 11 and can slide along the cooling plate 11. Subsequent storage containers will push the following storage containers to move backward along the upper surface of the cooling plate 11. The storage containers move backward along the cooling plate 11, passing through different cooling zones 111 in sequence for cooling. The temperature of the cooling zones 111 decreases from front to back, and the prepreg resin and cooling plate 11 will not form an excessive temperature difference. Gradual cooling ensures the cooling effect and avoids excessive temperature difference affecting the performance of the prepreg resin. Finally, the prepreg resin that has slid to the rear end of the cooling plate 11 and completed cooling is taken out from the outlet 13 of the cooling box 1, which is convenient to operate. The inlet 12 is located at the front end of the cooling plate 11, and the outlet 13 is located at the rear end of the cooling plate 11, which ensures that the prepreg resin is first-in, first-out and reduces the risk of errors during removal. The storage container must have good thermal conductivity.

[0027] The upper surface of the cooling plate 11 is horizontally set, and the storage container for storing the prepreg resin to be cooled can be stably placed on the cooling plate 11. The upper surface of the cooling zone 111 and the upper surface of the heat insulation plate 112 are smoothly connected, and the subsequent storage container can smoothly push the rear storage container to move forward along the upper surface of the cooling plate 11.

[0028] The cooling plate is provided with a first cooling zone 113, a second cooling zone 114, a third cooling zone 115, a first heat insulation plate 116, and a second heat insulation plate 117. The first heat insulation plate 116 is located between the first cooling zone 113 and the second cooling zone 114, and the second heat insulation plate 117 is located between the second cooling zone 114 and the third cooling zone 115.

[0029] The cooling zone 111 includes a cooling pipe 1111, a water inlet connector 1112, and a water return connector 1113. The water inlet connector 1112 and the water return connector 1113 are respectively located at both ends of the cooling pipe 1111 and are both connected to the cooling pipe 1111. The cooling pipe 1111 is coiled inside the cooling zone 111.

[0030] Both the inlet connector 1112 and the return connector 1113 are located outside the cooling box 1 and on the same side of the cooling box 1. The inlet connector 1112 and the return connector 1113 are convenient for connecting to the external circulating water pipe. Different cooling zones 111 can be independently connected to the external circulating water pipe. Cooling zones 111 with the same temperature can also share the same circulating water pipe as needed, thereby saving resources.

[0031] The cooling box 1 includes multiple cooling plates 11, which are arranged in layers and parallel to each other.

[0032] The cooling box 1 includes a first cooling plate 14 and a second cooling plate 15. The first cooling plate 14 is located directly above the second cooling plate 15. In this embodiment, the height of the first cooling plate 14 is between 0.9 meters and 1.3 meters, the height of the second cooling plate 15 is between 0.5 meters and 0.9 meters, and the distance between the first cooling plate 14 and the second cooling plate 15 is between 0.3 meters and 0.6 meters. The heights of the first cooling plate 14 and the second cooling plate 15 are moderate and both are in positions that are easy to pick up and put down.

[0033] The cooling plate 1 also includes a front extension 16 and a rear extension 17. The front extension 16 is located at the front end of the cooling plate 1, and the rear extension 17 is located at the rear end of the cooling plate 1. Both the front extension 16 and the rear extension 17 extend outside the cooling box 1, making it more convenient to store and retrieve materials.

[0034] The cooling device also includes trays made of a material with excellent thermal conductivity, with prepreg resin placed inside. In use, the trays are pushed sequentially onto the cooling plate 11 from the front. Subsequent trays push the trays behind them backward, placing them sequentially on different cooling zones 111 for gradual cooling. The size of the cooling zone 111 is adapted to the size of the tray, enabling automatic positioning. In this embodiment, the trays are made of an alloy material with excellent thermal conductivity.

[0035] The working method of this application is as follows:

[0036] The prepreg resin to be cooled is placed in a tray, and the trays are pushed into the cooling box 1 sequentially from the inlet 12. The tray containing the prepreg resin is placed on the cooling plate 11 and can slide along the cooling plate 11. Subsequent trays will push the trays behind them to move backward along the upper surface of the cooling plate 11. The trays move backward along the cooling plate 11, passing through different cooling zones 111 in sequence for cooling. The temperature of the cooling zones 111 decreases sequentially from front to back, and there is no excessive temperature difference between the prepreg resin and the cooling plate 11. The gradual cooling ensures the cooling effect and avoids excessive temperature difference from affecting the performance of the prepreg resin. Finally, the prepreg resin that has slid to the rear end of the cooling plate 11 and has completed cooling is taken out from the outlet 13 of the cooling box 1, which is convenient to operate. The inlet 12 is located at the front end of the cooling plate 11, and the outlet 13 is located at the rear end of the cooling plate 11, which can ensure that the prepreg resin is first-in and first-out and is less likely to be mistaken when taking it out.

Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
