[0030] The heat dissipation mechanism is arranged on the top of the base 1, which is used to prevent overheating caused by long-time operation of the device. The heat dissipation mechanism comprises a heat conduction block 11, a heat conduction pipe 12, a heat dissipation plate 13 and an axial flow fan 16. One side of the equipment box 2 is fixedly connected with an operation box 5. The output end of the motor 4 penetrates through one side of the operation box 5 and is fixedly connected with a driving disc 8. One side of each of a plurality of heat conduction blocks 11 is fixedly connected to one side of the driving disc 8. One end of each of a plurality of heat conduction pipes 12 is fixedly connected to the outer wall of each of the plurality of heat conduction blocks 11. The other end of each of the plurality of heat conduction pipes 12 is fixedly connected to one side of the heat dissipation plate 13. One side of the operation box 5 is fixedly connected with a sleeve 15. The sleeve 15 is provided with a heat dissipation opening on one side. The outer wall of the axial flow fan 16 is fixedly connected to the inner wall of the heat dissipation opening. Thus, when the motor 4 starts to work, the output end drives the driving disc 8 to rotate. The rotation of the driving disc 8 further drives the driven disc 14 and the plurality of heat conduction blocks 11 fixed between the driving disc 8 and the driven disc 14 to rotate synchronously through the connecting rod 9. The heat conduction block 11 is close to the roller 10 during rotation, so that the heat generated by the friction between the roller 10 and the flexible pipe 7 can be conducted to the heat dissipation plate 13 through the heat conduction pipe 12 on the outer wall of the heat conduction block 11. The heat dissipation plate 13 serves as a main heat dissipation surface, thereby increasing the heat exchange area. Meanwhile, the axial flow fan 16 works in the heat dissipation opening of the sleeve 15 to generate airflow to extract the hot air in the sleeve 15, thereby effectively taking away the heat on the heat dissipation plate 13 and achieving heat dissipation and cooling of the device.

[0031] The preheating mechanism is arranged on the top of the base 1, which is used to reduce the thick consistency of the extracted liquid. The preheating mechanism comprises a heating box 18, a heat conduction plate 19 and a heating wire 20. The bottom of the heating box 18 is fixedly connected to the top of the base 1. Each of the two heat conduction plates 19 is fixedly connected to the inner wall of the heating box 18. The two ends of each of the plurality of heating wires 20 are fixedly connected to the inner walls on the two sides of the heating box 18. The outer wall of each of the plurality of heating wires 20 is tightly attached to one side of each of the two heat conduction plates 19. Each of the two sides of the heating box 18 is fixedly connected with a conveying pipe 21. One end of one of the conveying pipes 21 is fixedly connected with the flexible pipe 7. Thus, when the thick consistency of the liquid is high, the heating wire 20 in the heating box 18 is started. The heating wire 20 in the heating box 18 generates heat after being electrified. The heat is uniformly transmitted to the liquid in the heating box 18 through the heat conduction plate 19. When the liquid is heated, the internal molecular movement of the liquid will be accelerated, thereby reducing the thick consistency of the liquid and making the liquid more thin and more convenient to be squeezed out by the roller 10, thereby reducing the wear of the flexible pipe 7 and the working burden of the motor 4. The liquid can be conveyed to the flexible pipe 7 through the conveying pipe 21, thereby conveying the liquid to the required position.
