Multiple nozzles in a uniform linear array are fixedly connected to the upper end of the lower drain pipe 227.

The inner wall of the steel strip 16 is cooled by water spraying; multiple nozzles in a uniform linear array are fixedly connected to the lower end of the upper drain pipe 228, and the nozzles at the lower end of the upper drain pipe 228 are used to spray water to cool the inner wall of the upper steel strip 17 on the left side (7 meters); the inner wall of the upper steel strip 17 is provided with a guide groove; a water collection tank 232 is fixedly connected to the lower left side of the mounting frame 15; temperature sensors are fixedly connected to the inlet of water pump 1 221, the outlet of hot water exchange tank 1 222, the inlet of water pump 2 225, and the outlet of hot water exchange tank 2 226.

The lower and upper steel belts 16 work together to move the rubber belt to the left. Water pump 221 drives water into the heat exchange tank 222, where it is heated to warm water. This warm water then flows through pipes into the lower drain pipe 223 and the upper drain pipe 224. The warm water inside the lower drain pipe 223 is evenly sprayed onto the inner wall of the lower steel belt 16 through nozzles, thus irrigating the 3-meter section of the lower steel belt on the right side. The lower steel strip 16 undergoes initial cooling. Warm water cools the lower steel strip 16 and drips into the inner side of the water collection tank 231, then flows back through a pipe to the inlet of the water pump 221. Warm water inside the upper drain pipe 224 is evenly sprayed onto the inner wall of the upper steel strip 17 through nozzles, achieving initial cooling of the upper steel strip 17 on the right side (3 meters). After cooling the upper steel strip 17, the warm water drips into the inner side of the water collection tank 231 through a guide channel and flows back through a pipe to the inlet of the water pump 221, thus achieving warm water cooling water circulation. Water is then driven by the second water pump 225 to flow into the inner side of the second heat exchange tank 226 for heat exchange, transforming it into cold water. The cold water then flows through a pipe into the lower... Cold water from inside drain pipe 227 and upper drain pipe 228 is evenly sprayed onto the inner wall of the lower steel strip 16 through nozzles, further cooling the 7-meter section of the lower steel strip 16 on the left side. After cooling the lower steel strip 16, the cold water drips into the inner side of water collection tank 232 and flows back to the inlet of water pump 225 through pipes. Cold water from inside upper drain pipe 224 is evenly sprayed onto the inner wall of the upper steel strip 17 through nozzles, further cooling the 7-meter section of the upper steel strip 17 on the left side. After cooling the upper steel strip 17, warm water drips into the inner side of water collection tank 231 through a guide channel and flows back through pipes. The water flows to the inlet of water pump 221 to achieve cold water cooling; thus, it realizes the staged cooling of the lower steel strip 16 and the upper steel strip 17. Based on the feedback data from the temperature sensor, the system automatically adjusts the flow rate and power of water pump 221 and water pump 225, and accurately controls the temperature through hot water exchange tank 222 and hot water exchange tank 226 to achieve indirect staged cooling of the rubber, ensuring the uniform and stable temperature of the rubber during the molding process, and avoiding the rubber from breaking or yellowing due to temperature differences; the left end of the mounting bracket 15 is 50mm lower than the right end to ensure the flow of cooling water on the inner wall of the upper steel strip 17.

[0037] The floating pressing assembly 4 includes an L-shaped block 41, a spring 42, and a pressure roller 43. Multiple L-shaped blocks 41 are fixedly connected in a uniform linear array on the upper end of the mounting frame 15. A pressure roller 32 is rotatably connected to the lower end of the L-shaped block 41. One end of the spring 42 is fixedly connected to the mounting frame 15. The other end of the spring 42 is fixedly connected to the L-shaped block 41. The pressure roller 43 is rotatably connected to the upper steel belt 17.

[0038] In this invention, when the rubber is squeezed to the left by the filter press 12, the output end of the cylinder 31 drives the pressure roller 32 to move downward. The pressure roller 32, together with the fixed roller 33, pre-presses the rubber. When the lower steel belt 16 and the upper steel belt 17 drive the rubber to move to the left, the spring 42 ensures that the L-shaped block 41 always has a tendency to drive the pressure roller 43 to press downward, thereby ensuring that the thickness of the rubber remains consistent during transportation.
