Faster, its cooling effect is promoted.
Further setting：The water inlet end and water outlet are fixedly connected with respectively close to one end of roll shaft in water inlet sealing plate
On water outlet sealing plate, and the water inlet and water outlet are provided with diffluence pass close to one end of roll shaft.
So set, by being fixedly connected on water inlet end and water outlet on water sealing plate and water outlet sealing plate, so that
The circulation of the water inlet end progress cooling water more stable with water outlet, the diffluence pass opened up increase cooling water and circulate into splitter cavity
Speed, water speed was promoted, to promote cooling effect.
Further setting：The water inlet end and water outlet are all set on the central axis of roller.
So set, being rotated by being positioned on the central axis of roller convenient for external rotating device pair roller barrel
Centrifugal force is generated, so that the cooling water crossed in water interlayer is concentrated to the peripheral wall of roller, promotes the cooling effect to product.
Further setting：The water inlet end and water outlet are respectively connected with far from one end of roll shaft for driving roller to rotate
Rotary joint.
So set, by the rotary joint of setting, so that roller is driven to be rotated, so that centrifugal force is generated, it is cooling
Water is concentrated on the peripheral wall of roller, promotes the cooling effect to product.
Further setting：The inner hollow of the roll shaft is arranged, and the water inlet sealing plate and water outlet sealing plate will be described
Roll shaft sealing.
So set, mitigating the weight of roll shaft by the way that roll shaft inner hollow to be arranged, to mitigate whole chilling roll
Weight is convenient for using and intaking sealing plate and water outlet sealing plate seals roll shaft, avoid making in cooling water inflow roll shaft
It obtains cooling water to concentrate in water interlayer, promotes the cooling effect to product.
Further setting：Heat insulating coat is coated on the surfaces externally and internally of the roll shaft.
So set, the temperature capability of roll shaft entirety is promoted, to promote the use of roll shaft by the heat insulating coat being coated with
Service life.
Further setting：The outer layer of the roller is equipped with smooth abrasion-proof coating.
So set, smooth abrasion-proof coating is coated with by the outer layer in roller, so that product and frictional force when contacting
It is smaller, the cooling effect to product entirety is promoted, and be set as the wear resistance that wearing layer promotes roller outer layer, promotes it and use the longevity
Life.
By using above-mentioned technical proposal, the utility model is compared compared with the prior art, is had the following advantages that：
