Description

Technical Field

[0001] The utility model relates to the technical field of cooling rollers, in particular to a cooling roller with uniform cooling. Background Art

[0002] The cooling roller is a roller that has cooling water or coolant flowing through it. When calendering films or applying adhesive tapes, in order to reduce the deformation caused by the shrinkage of the hot material when it is cooled when the finished product is rolled, the material is passed through the cooling roller before rolling to reduce the deformation of the material.

[0003] At present, during the use of the existing cooling roller, due to its long length, the degree of cooling of the outer surface of the roller gradually decreases in the direction away from the cooling water inlet, resulting in uneven cooling of the outer surface of the roller, thereby affecting the use effect of the cooling roller. Summary of the invention

[0007] Furthermore, the outer surface of the cooling roller body is plated with a chrome layer.

[0008] Furthermore, a partition is fixedly connected between the outer surface of the central axis and the inner wall of the water storage cavity.

[0009] Furthermore, the drainage cavity is arranged outside the water inlet cavity.

[0010] Furthermore, the cooling chamber is arranged outside the water storage chamber.

[0011] The beneficial effects of the utility model are:

[0012] 1. Cooling water is transported from the water inlet to the water inlet chamber, and then flows into the water storage chamber through the connecting pipe for storage, and then flows evenly into the cooling chamber from the diversion hole, so as to evenly cool the roller and improve the use effect of the cooling roller.

[0013] 2. The water storage chamber is divided into two independent spaces by setting a partition, so as to achieve better cooling. BRIEF DESCRIPTION OF THE DRAWINGS
