The cooling method for linear materials is mostly water cooling. Currently, some existing water cooling equipment has difficulty removing water stains from the resin surface after cooling, which affects the subsequent pelletizing steps and reduces the quality of resin granulation.

There are two groups of wiping sponge plates 15, with a wiping space between the two groups of wiping sponge plates 15.

[0021] Furthermore, a connecting plate is fixedly installed on the front inner wall and the rear inner wall of the cooling box 1. A pull rod 5 is slidably installed on the top of the connecting plate. One end of the pull rod 5 extends into the interior of the cooling box 1 and is fixedly installed on a U-shaped plate 6. A second electric conveying roller 17 is rotatably installed on the front inner wall and the rear inner wall of the U-shaped plate 6. Two sets of mounting blocks 7 are fixedly installed on the top of the connecting plate. The pull rod 5 is located between the two sets of mounting blocks 7, and openings are provided on both sets of mounting blocks 7 and the pull rod 5. A limit plate 8 is slidably installed on the inner wall of the opening. This arrangement can drive the second electric conveying roller 17 to perform lifting and lowering. This arrangement can adjust the height of the second electric conveying roller 17 according to the thickness of the linear resin raw material 9, increase the time that the linear resin raw material 9 is immersed in the interior of the cooling box 1, and thus improve the cooling effect of the linear resin raw material 9.

[0022] Furthermore, an extension plate 10 is fixedly installed on one side of the cooling box 1. A fixing rod 11 is fixedly installed on the top of the extension plate 10. A mounting top plate 12 is fixedly installed on the top of the fixing rod 11. A connecting block 13 is fixedly installed on the bottom of the mounting top plate 12. The bottom of the connecting block 13 is fixedly installed to the top of one set of wiping sponge plates 15. Sliding plates 14 are fixedly installed on both the front and rear sides of the other set of wiping sponge plates 15. The sliding plates 14 are slidably installed with the fixing rod 11. A compression spring 16 is fixedly installed on the bottom of the other set of wiping sponge plates 15. The bottom of the compression spring 16 is fixedly installed to the top of the extension plate 10.

[0023] Working principle: In use, the linear resin material 9 is conveyed by the first electric conveying roller 2 and the second electric conveying roller 17. When the linear resin material 9 is relatively thick, the limiting plate 8 is moved first. After the limiting plate 8 moves, the limiting of the pull rod 5 and the mounting block 7 can be released. Then the pull rod 5 is lifted upward. The movement of the pull rod 5 drives the U-shaped plate 6 and the second electric conveying roller 17 to move. After the second electric conveying roller 17 is moved away from the inner bottom of the cooling box 1, the time of the linear resin material 9 in the cooling box 1 can be increased. When the linear resin material 9 is conveyed, it will pass between the two sets of wiping sponge plates 15. Then the two sets of wiping sponge plates 15 can remove the water stains adhering to the outer wall of the linear resin material 9.
