Description
Technical Field
The utility model belongs to the technical field of lithography apparatus, concretely relates to water-cooling roller.
Background
The inside water conservancy diversion line that does not have of traditional lithography apparatus chill roll, the cooling water just can the overflow when the roller gathers about half, speed's homogeneity when leading to the interior ponding cold water of roller to influence the high-speed rotation of roll body causes the operation influence. The traditional solution is to use a motor to drive such a cooling roller, which increases the cost considerably.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a water-cooling roller to solve the problem that proposes in the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme: the water-cooling roller comprises a large circular aluminum pipe, wherein a small circular aluminum pipe is arranged in the large circular aluminum pipe, a flow guide groove is arranged in the space between the large circular aluminum pipe and the small circular aluminum pipe, spiral threads are welded in the flow guide groove, supporting flanges are installed at two ends of the large circular aluminum pipe, supporting shafts are installed at two ends of the small circular aluminum pipe, bearing seats are installed at the outer ends of the supporting shafts, ball bearings are installed on the bearing seats, rotary joints are installed on the ball bearings, and a hole channel communicated with the flow guide groove is formed in one side of each supporting shaft.
Preferably, one of the two rotary joints is a water inlet, the other one is a water outlet, and the water inlet and the water outlet are communicated with the diversion trench through a flow channel and a pore channel on the supporting shaft.
Preferably, the middle part of the support shaft is provided with a flow channel, and the flow channel is communicated with the pore channel on one side of the support shaft.
The utility model discloses a technological effect and advantage: the water-cooled roller can reduce the equipment cost, increase the equipment operation precision and greatly improve the service life of the cooling roller; the roller is made of full aluminum materials, cooling water flows into the diversion trench through the rotary joint, the interior of the diversion trench is filled with water pressure very quickly, spiral threads are welded in the diversion trench, and spiral force can be generated under the help of the spiral threads under the impact of a cooling water pump, so that the roller body generates self-supply power.
