Description
Technical field
The utility model relates to a kind of rollers.
Background technique
At present in the production line of sheet material or film, in order to reduce the temperature of roller surface, the quality of product is improved, often
Water-cooling structure is set in roller, and water-cooling structure is typically located at the vertical bar shaped water stream channel in roller, and vertical bar shaped water flow is logical
Water inlet, the water outlet in road are separately positioned on the both ends of roller.Cooling water is flowed to through vertical bar shaped water stream channel from one end of roller
The other end of roller makes the outer surface of roller cool, to improve the quality of product.But since vertical bar shaped water flow is logical
Cooling water in the road temperature in flow process gradually rises, and it is inconsistent that this will cause roller surface temperature（Roll surface temperature is from straight
The water inlet of bar shaped water stream channel to its water outlet gradually rises）, and the bigger temperature difference of roll surface width is bigger, directly results in production
Sheet material lateral error is big, results even in roller and deforms.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of uniform rollers of surface temperature.The technical side of use
Case is as follows：
A kind of roller, including cylinder, it is characterised in that：The first helical form water stream channel and the second spiral shell are equipped in the cylinder
Shape water stream channel is revolved, the first helical form water stream channel is parallel to each other with the second helical form water stream channel；First helical form water flow is logical
The water inlet in road, the second helical form water stream channel water outlet be set to the left end of cylinder, the first helical form water stream channel goes out
The mouth of a river, the second helical form water stream channel water inlet be set to the right end of cylinder；The cross section face of first helical form water stream channel
Product gradually becomes smaller from its water inlet to water outlet, and the cross-sectional area of the second helical form water stream channel is from its water inlet to water outlet
It gradually becomes smaller.
When above-mentioned roller works, the cooling water in the first helical form water stream channel flows to the right side of cylinder from the left end of cylinder
End, while the cooling water in the second helical form water stream channel flows to the left end of cylinder, the outer surface of pair roller barrel from the right end of cylinder
It cools down, the cooling water in two helical form water stream channels is gradually warmed up in flow process.Due to the first spiral
Cooling water in cooling water and the second helical form water stream channel in shape water stream channel flows on the contrary, roller therefore can be effectively reduced
The temperature difference of surface everywhere, it is ensured that roller surface temperature is uniform, is conducive to improve product quality, prevents roller from deforming.Moreover,
