Description

Technical Field

[0001] The utility model relates to the technical field of carbon fiber tube production, in particular to a cooling device for carbon fiber tube production. Background Art

[0002] A carbon fiber tube refers to a round tube made by pre-impregnating a carbon fiber composite material with a styrene-based polyester resin and then heating, curing and pultruding. During the production process of the carbon fiber tube, the produced carbon fiber tube must be cooled. Therefore, a cooling device for the production of carbon fiber tubes is required.

[0003] For this purpose, Chinese patent with publication number CN213593690U discloses a cooling structure for carbon fiber tube production, including a box body, an outer wall of the box body is provided with a feed inlet, the bottom wall of the box body is fixedly connected with a support leg, the bottom wall of the box body is plugged with a water outlet pipe, the bottom wall of the box body is connected with a first water pump by bolts, the end of the water outlet pipe away from the box body is connected to the outer wall of the first water pump, the output end of the first water pump is connected to the first water pipe, the outer wall of the box body is provided with a feed outlet, and the inner wall of the box body is connected with a conveying mechanism; when the utility model cools down the carbon fiber tube, a large amount of water vapor will be generated if the high and low temperature difference is too large, and the water vapor will generate water droplets after cooling, which will flow to the bottom wall of the box body, and the water in the inner cavity of the box body is extracted by the first water pump, and then the extracted water is conveyed to the third water pipe through the first water pipe for cooling, recycling, and saving water resources.

[0004] However, in this patent, when using it to cool the multiple carbon fiber tubes produced, the multiple carbon fiber tubes produced are allowed to enter the box 1 through the feed port 2, and then the multiple carbon fiber tubes are transported to the cooling ring 17 for cooling through the conveying wheel 13 on the conveying mechanism 12. Since the newly produced carbon fiber tubes are relatively soft and each carbon fiber tube is not cooled separately, squeezing may occur between the multiple carbon fiber tubes, which may cause the carbon fiber tubes to deform and easily damage the appearance of the carbon fiber tubes. In addition, in this patent, when using it to cool the produced carbon fiber tubes, since the cooling water is located inside the cooling ring 17, the carbon fiber tubes have no direct contact with the cooling water, which makes the cooling effect on the produced carbon fiber tubes not very good, thereby reducing its cooling effect.

The protective placement component can place and protect the carbon fiber tube body 17 through the setting of the carbon fiber tube body 17, the protective placement component, the first limiting component, the second limiting component and the first positioning component. The first limiting component and the second limiting component can both limit the carbon fiber tube body 17. The first positioning component is capable of positioning the protective placement component. When the device is used to cool the multiple carbon fiber tube main bodies 17 produced, the device can cool each carbon fiber tube main body 17 individually, so that the multiple carbon fiber tube main bodies 17 are prevented from being squeezed against each other, and the device can prevent the multiple carbon fiber tube main bodies 17 from being deformed due to mutual squeezing, and the device can prevent the multiple carbon fiber tube main bodies 17 from being easily damaged in appearance due to deformation, so that the device is not easy to damage the appearance of the carbon fiber tube.

[0033] like Figures 1 to 10As shown: a cooling device for carbon fiber tube production, comprising a carbon fiber tube body 17, a supporting bottom plate 13, a cooling box 7, a drain pipe 12, a gate-shaped long plate 8 and a T-shaped plate 4, the number of carbon fiber tube bodies 17 is multiple, a second circular plate 15 is fixedly installed on the inner bottom wall of the cooling box 7, a second water inlet long hole 14 is opened on the front side and the left side of the second circular plate 15, a positioning vertical rod 16 is movably installed inside the plate body of the second circular plate 15, the left inner wall and the right inner wall of the cooling box 7 are fixedly connected to the limiting long rod 9, the internal thread connection of the drain pipe 12 is connected to the flow stopper 11, the internal sliding connection of the gate-shaped long plate 8 is connected to a hook-shaped straight plate 5, one side of the hook-shaped straight plate 5 is fixedly connected to the limiting vertical plate 27, the internal thread connection of the plate body of the hook-shaped straight plate 5 is connected to the first bolt 6, the number of the hook-shaped straight plates 5 and the number of the first bolts 6 are both Two, one side of the T-shaped plate 4 is respectively provided with a first thread groove 24 and a second thread groove 23, and the first thread groove 24 and the second thread groove 23 are both threadedly connected to the first bolt 6. Through the setting of the drainage component, the device can discharge the used cooling water, and through the setting of the carbon fiber tube main body 17, the cooling component, the operating component and the second positioning component, the cooling component can cool multiple carbon fiber tube main bodies 17, the operating component can operate the protective placement component, and the second positioning component can position the operating component. When the device is used to cool the multiple carbon fiber tube main bodies 17 produced, the multiple carbon fiber tube main bodies 17 can be in direct contact with the cooling water, so that the multiple carbon fiber tube main bodies 17 produced can be fully cooled, so that the device can improve the cooling effect.

[0034] During use, after the multiple carbon fiber tube bodies 17 are individually placed in the placement table 1, when the multiple carbon fiber tube bodies 17 produced need to be cooled, the two first bolts 6 are rotated at the same time to disconnect the first bolts 6 from the first thread groove 24 and to locate one end of the first bolt 6 inside the plate body of the hook-shaped straight plate 5, and at the same time, the two hook-shaped straight plates 5 are moved downward to slide the hook-shaped straight plates 5 downward along the T-shaped plate 4, the door-shaped long plate 8 and the cooling box 7 respectively, to slide the limiting vertical plate 27 downward along the door-shaped long plate 8, to move the placement table 1, the first limiting long plate 3 and the second limiting long plate 22 downward, and to move the first circular plate 10 along the cooling box 7 respectively. 7 and the limit long rod 9 slide, so that the positioning rod 16 moves downward.

Cooling water is added to the cooling box 7 along the cooling box 7 to gradually fill the cooling box 7 with cooling water. When the placement table 1 is completely immersed in the cooling water in the cooling box 7, the cooling water is stopped from being added to the cooling box 7. The cooling box 7 is gradually filled with cooling water until the placement table 1 is completely immersed in the cooling water in the cooling box 7. During the process of the placing table 1 being completely immersed in the cooling water in the cooling box 7, the cooling water in the cooling box 7 enters the second circular plate 15 along the second water inlet long hole 14.

At this time Under the cooling effect of cooling water, the device can cool the multiple carbon fiber tube main bodies 17 produced. When the device cools the multiple carbon fiber tube main bodies 17 produced, the multiple carbon fiber tube main bodies 17 can be in direct contact with the cooling water, so that the multiple carbon fiber tube main bodies 17 produced can be fully cooled, so that the device can improve the cooling effect. When the device needs to discharge the used cooling water, the stop plug 11 is rotated to disconnect the stop plug 11 from the drain pipe 12, so that the drain pipe 12 is opened, and the used cooling water in the cooling box 7 is discharged along the drain pipe 12. At this time, the device can discharge the used cooling water.

[0035] In this embodiment, the top and bottom of the second position-limiting long plate 22 are both arc surfaces, and the first thread groove 24 is located at the top of the second thread groove 23 .
