[0027] The driving assembly 3 includes two left and right screw rods 31, and the two screw rods 31 are rotatably connected to the front and back of the inner wall of the square support frame 1. The back of the square support frame 1 is fixedly connected to a driving motor 32, and the output end of the driving motor 32 is fixedly connected to one end of the right screw rod 31. The other ends of the two screw rods 31 are fixedly connected to pulleys 33, and the two pulleys 33 are connected through belt transmission.

[0028] The flip assembly 4 includes two left and right moving blocks 41, and the two moving blocks 41 are respectively threadedly connected to the surfaces of the two screw rods 31. The tops of the two moving blocks 41 are rotatably connected to the placement plates 42.

The bottom of the placement plate 42 is slidably connected to the connecting plate 45, and the telescopic end of the hydraulic cylinder 44 is rotatably connected to the connecting plate 45.

[0029] When cooling the polyethylene sheet, the polyethylene sheet is flipped to a vertical position by the action of the flipping component 4, and the polyethylene sheet is cooled on both sides with the cooperation of the cooling spray component 2, so that the polyethylene sheet can be quickly cooled on both sides, thereby improving the practicality of the device when used.

[0030] The second embodiment is mainly different from the first embodiment in that: the detection component 5 detects the position of the moving polyethylene plate and controls the cooling spray component 2 to work and stop when the polyethylene plate enters and leaves the cooling spray component 2, thereby reducing the waste of cooling water. The detection component 5 includes an L-shaped bracket 51 and an infrared sensor 52, and the infrared sensor 52 is used to detect the position of the polyethylene plate.

The drive motor 32 rotates and drives the screw rod 31 connected to it to rotate, and under the transmission of the two pulleys 33 and the belt, the two screw rods 31 rotate at the same time, thereby driving the two placement plates 42 to move. When the polyethylene plate begins to enter the bottom of the water supply pipe 23, the infrared sensor 52 detects the position of the polyethylene plate. After detection, the solenoid valve 25 is controlled to open and work with the water pump 22, thereby starting spraying, and the polyethylene plate entering the cooling spray assembly 2 is sprayed on both sides.
