[0032] The cooling mechanism comprises a first cooling assembly and a second cooling assembly which are interconnected, wherein the first cooling assembly is arranged on the conveying mechanism 1 to cool the conveying mechanism 1, and the second cooling assembly is arranged on the conveying mechanism 2 to cool the strip rubber;

[0033] A spraying mechanism is arranged below the conveying mechanism three, a water outlet end of the spraying mechanism is arranged on the conveying mechanism two, the spraying mechanism is located in front of the second cooling assembly, and the spraying mechanism is used to spray cooling water onto the surface of the strip rubber;

[0034] The water cleaning mechanism is arranged on the conveying mechanism three, and is used for cleaning the cooling water on the surface of the strip rubber and directing the cooling water into the spraying mechanism.

[0035] Furthermore, the conveying mechanism 1 includes two support frames 1 arranged at a relative interval, an active roller 3 and a plurality of driven rollers 4 are rotatably arranged between the two support frames 1, the active roller 3 is fixedly connected to the output shaft of the motor 2, the motor 2 is fixedly arranged on the support frame 1, and the plurality of driven rollers 4 are arranged at equal intervals along the length direction of the support frame 1, two cross bars 5 are fixedly connected to the inside of the bottom end of the support frame 1, a tensioning roller 6 is rotatably arranged between the two cross bars 5 located at the same end of the two support frames 1, a conveyor belt 7 is commonly wound around the outer sides of the active roller 3, the driven roller 4, and the tensioning roller 6, a support plate 8 is commonly fixedly connected to the top ends of the four cross bars 5, the support plate 8 is located inside the conveyor belt 7, and the first cooling component is fixedly arranged on the top end of the support plate 8.

[0036] Furthermore, the first cooling component includes an air compressor 31, which is fixedly arranged at the top of the support plate 8. The outlet end of the air compressor 31 is fixedly connected to one end of an air outlet pipe 32, and the other end of the air outlet pipe 32 is connected to a vortex tube 33. The air outlet pipe 32 is connected to the middle part of the side wall of the vortex tube 33 and is tangent to the side wall of the vortex tube 33. One end of the vortex tube 33 is fixedly connected to a hot air pipe 36, and the other end of the vortex tube 33 is fixedly connected to one end of a cold air pipe 34, and the other end of the cold air pipe 34 is connected to the second cooling component.

[0047] The water inlet pipe 13 can be used to fill the serpentine flow channel 37 with cooling water. The cooling water takes away the heat of the strip rubber in the process of advancing to the water outlet pipe 14 in the serpentine flow channel 37, thereby achieving a cooling effect. The spring 12 can automatically adjust the distance between the cooling plate 10 and the roller 15 to adapt to strip rubbers of different thicknesses.

[0049] By setting the arc shape, the strip rubber to be transported can be smoothly introduced between the cooling plate 10 and the roller 15.

[0050] The working process of the present invention is as follows:

[0051] The produced strip rubber is transported to the conveyor belt 7, which continuously rotates to transport the rubber forward. The temperature of the rubber will rise during the conveyor belt 7. Under the action of the air compressor 31 and the vortex tube 33, the cold air nozzle 35 will spray low-temperature gas to cool the conveyor belt 7. After the rubber is transported to the roller 15, it enters between the roller 15 and the cooling plate 10 and continuously moves forward. Cooling water continuously flows through the cooling plate 10 to cool the rubber. After the rubber moves forward and leaves the cooling plate 10, it reaches the bottom of the atomizing nozzle 21, and the atomizing nozzle 21 sprays mist cooling water onto the surface of the rubber to further cool the rubber, and then the rubber with cooling water continues to move to the bottom of the air nozzle 18, and the air nozzle 18 sprays low-temperature air to accelerate the evaporation of the cooling water and cool the rubber at the same time, and then the rubber enters between the roller 23 and the wiper protrusion 25, and the wiper protrusion 25 scrapes the water on the surface of the rubber and collects it in the water tank 28, and the water pump 29 pumps the cooling water in the water tank 28 back into the atomizing nozzle 21 and re-sprays it onto the rubber surface behind, so as to realize the recycling of cooling water.
