[0013] The following combines the attached Figure 1 , 2 to further illustrate the specific embodiments of the present utility model.

[0014] A liquid supply, return and cleaning system for carbon fiber felt spraying, including a variable-frequency liquid supply pump 1, the variable-frequency liquid supply pump 1 is sequentially connected to a cleaning liquid valve 2 and a cleaning liquid device 4, and the variable-frequency liquid supply pump 1 is sequentially connected to a liquid supply pump inlet valve 3, a liquid return device 5, a pressure transmitter 6, a liquid return valve 8, a liquid supply pump outlet valve 9, and a liquid supply telescopic pipe 11. A flowmeter 14 is provided between the variable-frequency liquid supply pump 1 and the liquid supply pump outlet valve 9. The liquid supply telescopic pipe 11 is vertically arranged, the bottom end of the liquid supply telescopic pipe 11 is connected to a spray head 13, the upper and lower parts of the liquid supply telescopic pipe 11 are fixedly connected to a lifting rod 12 through a fastening clip 15, the bottom end of the lifting rod 12 is fixedly connected to the spray head 13, the spray head 13 is horizontally arranged, a liquid receiving tank 10 is arranged below the spray head 13, and the liquid receiving tank 10 is connected to a waste liquid recovery device 7.

[0015] First, open the liquid supply pump inlet valve 3 and the liquid return valve 8, start the variable-frequency liquid supply pump 1, and perform internal circulation to fill the liquid in the pipeline and recover it into the liquid return device 5; when the pressure transmitter 6 shows that the set pressure is reached, open the liquid supply pump outlet valve 9 and close the liquid return valve 8 after a delay, and then the glue liquid enters the spray head 13 through the liquid supply telescopic pipe 11 to achieve the spraying effect, wherein the flowmeter 14 feeds back signals to control the output of the variable-frequency liquid supply pump 1; when the glue spraying work stops, to prevent the glue liquid in the pipeline from solidifying and causing blockage, the cleaning work must be carried out after each work is completed.
