Abstract

The invention discloses a film cooling roller which comprises a roller, a water distribution rotor and a movable joint, wherein the roller comprises a roller body, the roller body is in a round through shape, and cooling fins are arranged on the inner wall of the roller body; the movable joint comprises a water inlet connector and a water drainage connector; the water distribution rotor is coaxially arranged in the roller and comprises a water inlet channel, a water drainage channel and a rotor cylinder body; the water inlet connector is connected with the water inlet channel, and the water drainage connector is connected with the water drainage channel; the water inlet channel is arranged in the water drainage channel in a sleeved mode and communicated with a water inlet branch pipe arranged in the rotor cylinder body, and cooling water flows into the roller body for heat dissipation; and the water drainage channel is communicated with a water drainage main pipe arranged in the rotor cylinder body and is used for discharging cooling water of the roller body. The water inlet channel is arranged in the water distribution rotor to inject cooling water to cool the interior of the roller, and the roller and the water distribution rotor relatively rotate at a low speed under the acting force of cooling water flow, so that all parts of the circumference of the roller are uniformly cooled.

Description

technical field [0001] The invention relates to a film cooling roller, which belongs to the technical field of cooling mechanisms. Background technique [0002] Waterproof cardboard is usually covered with PE film and polyethylene film, and the film is usually produced continuously at high temperature. During the forming process of the film, the heat on the film will be transferred to the supporting roller in contact with it, making the temperature of the roller will also increase accordingly. If the temperature of the roller is too high, it will cause the film to be uneven, wrinkled or stick to the roller, which will affect the production quality and production efficiency of the film. Therefore, it is usually necessary to cool the supporting roller. A high-temperature water-cooled roll patented by Shougang Co., Ltd., ZL201420420119 .X, discloses a cooling roll, including a roll, a cooling roll, and a spiral blade-type flow guide mechanism on the cooling roll. The cooling w...
