The implementation principle of the embodiment is as follows:

after being extruded, the long plastic strip is first immersed into the cooling water tank 11, cooled and solidified by the cooling water in the cooling water tank 11, and after cooling, the long plastic strip is pulled out from the cooling water tank 11. Since the strip-shaped plastic is directly pulled out and easily scraped against the side wall of the cooling water tank 11, the strip-shaped plastic sequentially passes through the first guide roller 23 and the second guide roller 26, so that the possibility of scraping the strip-shaped plastic against the side wall of the cooling water tank 11 is reduced, and cooling water attached to the strip-shaped plastic falls back into the cooling water tank 11 under the action of gravity and the action of centrifugal force generated when the first guide roller 23 and the second guide roller 26 rotate. And then the strip-shaped plastic passes through the water suction port formed by the two water suction sponges 35, so that the cooling water remained on the strip-shaped plastic is absorbed by the two water suction sponges 35.

When the water absorption sponge 35 needs to be replaced, the water absorption sponge 35 can be taken down for replacement only by rotating the clamping rod 33 to enable the clamping rod 33 and the clamping groove 34 to be separated from the clamping connection state.

After the strip-shaped plastic is pulled out from the two water absorption sponges 35, the strip-shaped plastic penetrates into the through hole 42, and the first drying sponge 55 and the second drying sponge 59 arranged in the drying box 41 can further absorb the cooling water left on the strip-shaped plastic. When the relative position of the first drying sponge 55 and the second drying sponge 59 needs to be adjusted, the second driving rod 63 is screwed through the hand wheel 65, the second driving rod 63 drives the first driving rod 61 to rotate through the first bevel gear 62 and the second bevel gear 64 which are meshed with each other, and the first driving rod 61 drives the adjusting gear 51 to rotate.

Since both sides of the adjusting gear 51 are respectively engaged with the first rack 53 and the second rack 57, the first rack 53 and the second rack 57 are driven by the adjusting gear 51 to slide in opposite directions along the sliding slot 5, wherein the first rack 53 drives the first drying rod 54 and the first drying sponge 55 through the first sliding rod 52, the second rack 57 drives the second drying rod 58 and the second drying sponge 59 through the second sliding rod 56, and the first drying sponge 55 and the second drying sponge 59 are close to or far away from each other due to the opposite moving directions of the two. When the first drying sponge 55 and the second drying sponge 59 are close to each other and pressed, the moisture absorbed therein is also pressed out and falls into the drying box 41.

Meanwhile, the exhaust fan 45 is started, the exhaust fan 45 extracts air in the drying box 41 through the drying pipe 44, so that negative pressure exists in the drying box 41, the negative pressure extracts the air through the through hole 42 and the vent hole 43, the air flow formed by the negative pressure extraction air can blow off cooling water attached to the strip-shaped plastic, the strip-shaped plastic is continuously dried through the air flow, and the cooling water attached to the strip-shaped plastic after passing through the drying box 41 is greatly reduced. When the exhaust fan 45 performs air exhaust, the first drying sponge 55 and the second drying sponge 59 can shield the through hole 42 to increase the negative pressure in the drying box 41. The air entering the drying box 41 through the through holes 42 absorbs the cooling water inside the first drying sponge 55 and the second drying sponge 59 into the drying box 41, so as to enhance the absorption effect of the first drying sponge 55 and the second drying sponge 59 on the cooling water remaining on the strip-shaped plastic.

Although the cooling water remaining in the long plastic strip is not much, the cooling water in the drying box 41 gradually accumulates as the operation continues. At this time, only by screwing the adjusting handle 85, the adjusting handle 85 drives the adjusting ball 82 to rotate in the housing 81 through the adjusting rod 84, and the rotation of the adjusting ball 82 changes the portion where the adjusting hole 83 communicates with the internal cavity of the water return pipe 7, and when the adjusting hole 83 communicates with the internal cavity of the water return pipe 7 completely, the flow rate that the water return pipe 7 can pass through is the largest, and then the cooling water in the drying box 41 flows out along the water return pipe 7 and falls into a prepared container. When the cooling water in the drying box 41 flows out along the water return pipe 7, the adjusting rod 84 is rotated in the reverse direction again, so that the adjusting hole 83 is not communicated with the inner cavity of the water return pipe 7, the water return pipe 7 is closed, and the cooling water in the drying box 41 cannot flow out along the water return pipe 7.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
