[0021] like Figure 1-4 As shown, a circulation system for stabilizing the viscosity of carbon fiber pultrusion production fluid includes a bracket 1, a pump 2, a first pipe 3, and a second pipe 4. The bracket 1 is provided with a container 5 with an opening upward, the liquid inlet end of the pump 2 is connected to the bottom of the container 5 through the first pipe 3, the liquid outlet end of the pump 2 is connected to one end of the second pipe 4, and the other end of the second pipe 4 is located directly above the opening of the container 5. A carbon fiber stopper is provided below the opening in the container 5.
[0022] In this embodiment, when in use, the two ends of the carbon fiber 12 are in the container 5, so that the carbon fiber 12 can be immersed in the carbon fiber pultrusion production fluid. After that, the pump 2 sucks the carbon fiber pultrusion production fluid that has been soaked in the carbon fiber 1 in the container 5 and then injects it into the container 5 from the opening of the container 5 through the second pipe 4, thereby realizing the flow of the carbon fiber pultrusion production fluid. The carbon fiber limiter is provided to prevent the carbon fiber from falling off from the container 5 and causing it to not be immersed in the carbon fiber pultrusion production fluid.
[0023] As a preferred embodiment, the inner cross-section of the upper end of the container 5 is larger than the inner cross-section of the lower end, so that it is convenient for the pump 2 to suck the carbon fiber pultrusion production fluid.
[0024] As a preferred mode, a filter screen 6 is provided at the opening of the container 5, and the filter screen 6 is located below the end of the second pipe 4 away from the pump 2. The filter screen 6 is detachably fixedly connected to the left and right walls of the container 5, and a gap is preset between the filter screen 6 and the front wall of the container 5, and a gap is preset between the filter screen 6 and the rear wall of the container 5. In this way, after the filter screen 6 is provided, the carbon fiber pultrusion production fluid soaked with the carbon fiber 12 can be filtered once before flowing into the container 5 after passing through the pump 2, which mainly filters some impurities that fall off from the carbon fiber 12 in the carbon fiber pultrusion production fluid and some hard blocks left in the carbon fiber pultrusion production fluid due to solidification, so that the carbon fiber pultrusion production fluid in the container 5 can fully soak the carbon fiber 12.
[0025] As a preferred mode, the carbon fiber stopper includes a first main roller 7 and a second main roller 8, the first main roller 7 and the second main roller 8 are both rotatably arranged in the container 5 and located below the opening of the container 5, the first main roller 7 is located directly above the filter screen 6 and the front side wall of the container 5 and a preset gap is set between the front side wall of the container 5, and the second main roller 8 is located directly above the filter screen 6 and the rear side wall of the container 5 and a preset gap is set between the rear side wall of the container 5. (It is particularly noted that when in use, the carbon fiber 12 is moved along its axial direction by the driving mechanism, that is, the carbon fiber 12 only passes through the container 5, and will not remain in the container 5 without a breakage failure of the carbon fiber 12. The carbon fiber 12 in this application only draws the inner carbon fiber 12 located in the container 5) After such an arrangement, the first main roller 7 and the second main roller 8 are arranged to prevent the carbon fiber 12 from rubbing against the filter screen 6 during movement.

[0027] As a preferred embodiment, the height of the second auxiliary roller 10 is higher than or equal to the height of the top end of the rear side wall of the container 5 , and the height of the first auxiliary roller 9 is higher than or equal to the height of the top end of the front side wall of the container 5 .
[0028] As a preferred mode, a heating wire 11 is wound around the outer surface of the second pipe 4, a temperature sensor is provided in the container 5, and the temperature sensor signal is connected to the heating wire 11. After such arrangement, the carbon fiber pultrusion production fluid in the second pipe 4 is heated by the heating wire 11, thereby preventing the carbon fiber pultrusion production fluid from solidifying. The heating wire 11 is very common and can be purchased on the market. The schematic diagram is drawn in this application.
