Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of tire rubber processing, and particularly relates to a rubber strip double-drum spiral winding cooling device. BACKGROUND

[0002] After continuous hot extrusion of rubber products into rubber strips, the overall temperature of the rubber strips is high. In order to meet the requirements of the subsequent online bonding process, the temperature of the rubber strips needs to be reduced to a specified temperature, and the temperature needs to be kept constant during the continuous conveying of the rubber strips. At present, the commonly used methods for reducing the temperature of the rubber strips include air cooling and water cooling. The air cooling generally adopts the method of blowing air by multiple air blowers to cool the surface of the rubber strips. The cooling effect is greatly affected by the ambient temperature. In particular, in summer and in the absence of constant temperature and humidity in the factory building, it is difficult to achieve the cooling requirements. The water cooling generally adopts the method of immersing the rubber strips in a circulating water tank for cooling. At the same time, a fan needs to be added at the rear end to blow dry the water on the surface of the rubber strips. The circulating water also needs to have a cleanliness requirement to avoid contaminating the rubber material. The equipment occupies a large area. SUMMARY
