[0049] Specifically, the multi-way valve 601 is connected to the coolant tank 401 at the front, the recovery pipe 602 at the top, and an external waste heat recovery device at the right. The top of the multi-way valve 601 is fixedly connected to the rear right end of the top of the base 1. The recovery pipe 602 is fixedly connected to the top of the multi-way valve 601. The recovery pipe 602 connects the multi-way valve 601 and the airtight bearing 304 at the rear.

[0050] Working principle: The base 1 supports the entire device. The water cooling mechanism 4 starts working. The coolant stored in the coolant tank 401 is pumped by the liquid pump 402. During the pumping process, the coolant first passes through the filter 403 and the filter chamber 404 to filter the coolant and remove impurities, ensuring that the coolant entering the cooling roller 303 is pure. In the coolant output stage, the solenoid valve 4061 controls the coolant flow rate. Then, the coolant enters the threaded water channel 305 of the cooling roller 303 through the delivery pipe 4062 and the inner ring of the front airtight bearing 304. The drive motor 3063 is started, and the drive motor 3063 drives the drive gear 3062 to rotate. The drive gear 3062 and the drive... Gear 2 3061 meshes, thereby driving gear 2 3061 to rotate. Since the inner side of the driving gear 2 3061 is fixedly connected to the outer wall of the rear rotating rod 302, it drives the rotating rod 302 to rotate. The rotating rod 302 rotates stably on the rotating seat 2 through the fixed bearing 301, causing the cooling roller 303 fixedly connected to the rotating rod 302 to start rotating. During the rotation of the cooling roller 303, the coolant in the internal threaded water channel 305 flows spirally, better cooling the outer wall of the cooling roller 303. The film is placed between the support roller 502 of the support mechanism 5 and the cooling roller 303. The support roller 502 is rotatably connected to the rear side of the front rotating seat 2 through the support rotating shaft 501.

[0051] In the transmission assembly 503 behind the support roller 502, the transmission gear 5032 meshes with the drive gear 3061, transmitting the power of the drive motor 3063 to the support roller 502. The support roller 502 rotates synchronously with the cooling roller 303, tightly pressing the film. The film is uniformly cooled by the cooling roller 303. The cooled liquid flows into the recovery pipe 602 through the rear airtight bearing 304. The multi-way valve 601 is connected to the coolant tank 401 at the front, the recovery pipe 602 at the top, and an external waste heat recovery device at the right. The coolant can be recycled back to the coolant tank 401 through the multi-way valve 601. It can also be connected to an external waste heat recovery device for waste heat recovery. After the filter cartridge 404 has collected impurities for a period of time, it can be pulled out for cleaning and maintenance by sliding the bottom sliding component 405, i.e., the slide bar 4051, in the slide groove 4052 opened at the bottom inside the filter 403. This achieves efficient cooling processing of the weather-resistant membrane, ensures the quality of membrane production, and realizes the recycling and reasonable treatment of the coolant.
