Description

Technical Field

[0001] The utility model belongs to the technical field of resin processing, in particular to a carbon composite material impregnated resin device. Background Art

[0002] The carbon composite material resin impregnation device is a special equipment used to enhance the performance of carbon composite materials. It improves the density and various physical and chemical properties of the material by impregnating the carbon preform into a specific resin.

[0003] The existing carbon composite material impregnation resin device usually needs to frequently open the cover plate to load or discharge materials, which makes the sealing ring on the cover plate easy to loosen. After the cover plate is installed, the sealing ring on the cover plate is usually tightly attached to the impregnation tank and the resin melting tank by its own gravity. This method will result in poor sealing effect and easily allow air or impurities to enter, affecting the production of resin. Therefore, we propose a carbon composite material impregnation resin device. Utility Model Content

[0032] A specific application of this embodiment is:

[0033] When in use, the carbon preform is placed in the impregnation tank 14, the resin material is placed in the resin melting tank 13, and then the cover plate 11 is covered on the top of the box body 1. At this time, the two sealing covers 111 on the cover plate 11 are respectively plugged into the top of the impregnation tank 14 and the top of the resin melting tank 13, and the threaded shaft 172 is plugged into the cover plate 11. Since a sealing ring is provided inside the sealing cover 111, it can play a sealing role. After the cover plate 11 is covered, the pressing plate 121 is turned over to move the pressing plate 121 to At the top of the cover plate 11, the pressing plate 121 drives the fixing frame 122 to rotate on the connecting block 123. When the pressing plate 121 moves to the top of the cover plate 11, the pressing plate 121 is plugged into the threaded shaft 172 through the slide groove 124, and then the nut is threadedly connected with the threaded shaft 172 to squeeze and fix the pressing plate 121. Then, the cover plate 11 is pressed downward and fixed. At this time, the sealing rings in the two sealing covers 111 are respectively squeezed against the top of the resin melting tank 13 and the top of the impregnation tank 14, thereby improving the sealing effect;

[0034] Then, the heating and pressurizing base 2 is used to heat the resin melting tank 13 and the impregnation tank 14, and to pressurize the impregnation tank 14. The pressure gauge 116 is used to observe the pressure. At the same time, the stirring assembly 15 in the resin melting tank 13 is started, and the motor 81 is started to drive the belt pulley 153 at the rear to rotate, and the belt pulley 153 in front is driven by the belt to rotate, and the rotating rod 151 is driven to rotate. At this time, the stirring plate 152 stirs the resin in the resin melting tank 13 to make the internal heating more uniform. When the resin material is melted, the liquid pump 112 is started to pump the resin material into the conveying pipe 1 13 through the conveying pipe 2 117, and discharge it from the conveying pipe 1 13 into the impregnation tank 14. The staff rotates the handle 11 5 drives the threaded rod 114 to rotate, and at this time the threaded rod 114 will drive the second connection block 163 to move upward or downward, and the second connection block 163 will drive the tapered plug 161 to move together through the vertical rod 162, and the second connection block 163 will slide on the limiting rod 164. By adjusting the tapered plug 161, the size of the bottom opening of the conveying pipe 113 can be adjusted, so as to control the flow rate of the resin liquid, so that the resin can enter the impregnation tank 14 more evenly. After the resin enters the impregnation tank 14, the stirring assembly 15 in the impregnation tank 14 is started to stir the materials inside, so as to improve the mixing efficiency. Moreover, since the resin feeding speed is regulated, the carbon preform and the resin material can be mixed more fully;

[0036] The heating and pressurizing base 2 includes one or more electric heating elements, such as heating wires or electric heating plates. When the base is plugged into a power source and the switch is turned on, these electric heating elements will generate heat and transfer the heat to the object placed on the base by heat conduction. The pressurizing function is usually achieved by using a vacuum pump to extract air for pressurization, and the required pressure level is maintained by controlling the power of the vacuum pump.
