[0034] The working principle of this utility model is as follows: The inlet pipe 407 is connected to a water source. When the electric control valve on the side of the inlet pipe 407 is opened, cooling water enters the circulating water tank 301 through the inlet pipe 407. The cooling water inside the circulating water tank 301 enters the observation tube 401. The float 404 floats on the surface of the cooling water and moves up and down with the water level change. The amount of cooling water in the circulating water tank 301 is determined by the scale. As the cooling water level increases, the float 404 moves upward and contacts the first touch switch 402. The first touch switch 402 controls the electric control valve to automatically close. According to usage requirements, a hexagonal wrench is inserted into the hexagonal... Inside the slot 211, the rotating worm 207 meshes with the worm wheel 210, driving the bidirectional threaded shaft 205 to rotate. This, in turn, causes the threaded blocks 208 on both sides to move towards each other along the inner wall of the crossbeam 202, thereby causing the cantilever arms 203 to move laterally and adjusting the distance between the limiting plates 204 on both sides. Simultaneously, the side of the inclined surface 206 is in close contact with the side of the first and second extrusion rollers 103 and 104.

During this process, the limiting plates 204 on both sides limit the rubber to prevent it from moving to the sides of the first extrusion roller 103, thus maintaining a suitable width for the rubber. Simultaneously, the cooling water inside the circulating water tank 301 circulates through the water pump, connecting pipe 303, and mounting ring 304 into the heat exchange pipes 305 inside the first extrusion roller 103 and the second extrusion roller 104 to cool them down.
