Detailed Description

Referring to fig. 1-3, a multi-section calender roller comprises a main roller 1, a middle roller sleeve 2, a roller sleeve width adjusting block 3, a movable roller sleeve 4 and a screw rod 6, wherein an axial guide rib is arranged on the main roller 1, the roller sleeve width adjusting blocks 3 with different widths are increased or decreased, the screw rods 6 at two ends of the main roller 1 are used for propping against the movable roller sleeve 4, so that the roller sleeve width adjusting block 3 and the movable roller sleeve 4 move along the axial direction of the main roller 1 and are tightly connected with the middle roller sleeve 2 to form a roller surface for extruding sizing materials by the calender roller, a profiled groove is arranged on the surface of the movable roller sleeve 4, and the position of the profiled groove can be adjusted by increasing or decreasing the roller sleeve width adjusting blocks 3 with different widths.

The main roller 1 and the middle roller sleeve 2 are connected in an interference fit manner in a hot-shrink fit manner. The calender roll water inlet distributor 7, the medium flow channel 8 and the return channel 9 are designed in the middle of the main roll 1 and the middle roll sleeve 2 as shown in figure 2.

The same number of axial medium flow channels 8 are arranged on the same circumference close to the inner side of the surface of the middle roller sleeve 2, the roller sleeve width adjusting block 3 and the movable roller sleeve 4, between the middle roller sleeve 2 and the roller sleeve width adjusting block 3, the roller sleeve width adjusting block 3 and the movable roller sleeve 4 are respectively connected through the flow channel connecting pipe 11 to form a main medium flow channel 8, the flow channel connecting pipe 11 and the middle roller sleeve 2, and between the roller sleeve width adjusting block 3 and the movable roller sleeve 4, the high-temperature resistant rubber sealing ring 14 is used for sealing, so that medium leakage is prevented.
