Technical Field

[0001] The utility model relates to the technical field of prepreg cloth, in particular to a cooling device for a prepreg cloth shaping mold. Background Art

[0002] Prepreg is a reinforcing material used in composite material manufacturing. Its main components are fiber material (such as carbon fiber, glass fiber or aramid fiber) and resin (such as epoxy resin, phenolic resin or polyimide resin). Prepreg is a semi-solid material made by evenly impregnating the fiber material with resin, and then pre-curing it to a certain degree through heating, pressurization and other processes.

[0003] However, during the printing and shaping process of the prepreg, the surface of the material is still at a high temperature. Traditional natural cooling or static water cooling and bonding cooling are difficult to quickly and evenly reduce the temperature of the prepreg, affecting the cooling and shaping effect of the prepreg and product quality.

The rotating shaft of the first motor is fixedly connected to the end of the printing roller, and the rotating shaft of the second motor is fixedly connected to the end of the rotating roller.

[0009] Preferably, the outer wall of the water tank is connected to a water supply pipe.

[0010] Preferably, the U-shaped pipe, the water inlet pipe, the spiral pipe and the drain pipe are all metal pipes.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1 An embodiment of the utility model provides a cooling device for a prepreg shaping mold, comprising: a frame 1.

[0020] Among them, Figure 1-Figure 2 As shown, two first roller frames 4 are symmetrically installed on the top of the frame 1, and two printing rollers 7 are symmetrically installed on the adjacent sides of the two first roller frames 4 for rotation. Two second roller frames 5 are symmetrically installed on the top of the frame 1, and two rotating rollers 8 are symmetrically installed on the adjacent sides of the two second roller frames 5 for rotation.

[0021] Furthermore, a first motor 2 and a second motor 3 are installed on the top of the frame 1, and the ends of the two printing rollers 7 and the two rotating rollers 8 are fixedly connected with gears 6, and every two adjacent gears 6 are meshed with each other. The rotating shaft of the first motor 2 is fixedly connected to the end of the printing roller 7, and the rotating shaft of the second motor 3 is fixedly connected to the end of the rotating roller 8.

[0022] When in use, two printing rollers 7 are symmetrically installed on the first roller frame 4. Under the drive of the first motor 2, the gears 6 at the ends of the two printing rollers 7 can be meshed with each other, and the two printing rollers 7 are driven to perform surface printing and shaping treatment on the prepreg. At this time, the second motor 3 is started to drive the gears 6 at the ends of the two rotating rollers 8 to mesh with each other, so that the prepreg after printing and shaping is transported outward through the two rotating rollers 8.

[0023] In this embodiment, Figure 1-Figure 4 As shown, rotating pipe joints 9 are installed at both ends of the two rollers 8, and the inner walls of the two rollers 8 are fixedly connected with spiral tubes 15, wherein one end of the two rotating pipe joints 9 is connected to the water inlet pipe 14 and the drain pipe 13 in sequence, and the other end is connected to one end of the spiral tube 15, one end of the other two rotating pipe joints 9 is connected to the U-shaped tube 10, and the other end is connected to the other end of the spiral tube 15, and a circulating pumping mechanism is installed on the frame 1.

[0025] When in use, the water pump 11 is started to extract cooling water, and the cooling water is transported to the spiral tube 15 inside the roller 8 through the water inlet pipe 14, and the spiral tubes 15 inside the two rollers 8 can be connected through the U-shaped tube 10, so that the cooling water can flow through the spiral tubes 15 in the two rollers 8 and absorb the heat on the surface of the roller 8. The cooled water flows back to the water tank 12 through the drain pipe 13, forming a closed circulation cooling system, thereby completing the efficient cooling of the prepreg and achieving the purpose of cooling and shaping the prepreg.

[0026] It should be noted that, in order to improve the heat absorption effect of cooling water in the pipeline, the U-shaped tube 10, the water inlet pipe 14, the spiral tube 15 and the drain pipe 13 are all made of metal tubes, and in order to improve the heat absorption effect of the roller 8, the roller 8 is a copper roller.

The cooled water flows back to the water tank 12 through the drain pipe 13, forming a closed circulation cooling system, thereby completing the efficient cooling of the prepreg and achieving the purpose of cooling and shaping the prepreg.
