The abrasion generated by rotation between the calendaring roller body and the main shaft is reduced through the second bearing, so that the service life of the calendaring roller body is prolonged.

In a further technical scheme, the round hole pressing grooves are provided with four groups, and each group of round hole pressing grooves is provided with two rows.

The heat dissipation effect on the surface of the roller piece is improved through the plurality of round hole pressing grooves.

In a further technical scheme, the spraying thickness of the tungsten carbide coating is 0.15-0.3 mm.

The use effect of the tungsten carbide coating is improved through the thickness of the tungsten carbide coating.

In a further technical scheme, the groove depth of the round hole pressing groove is 10-40 μm.

The maximum use is generated at the most suitable depth by the groove depth of the round hole pressing groove, and the heat conduction capacity of the round hole pressing groove is improved.

The beneficial effects of the utility model are as follows:

1. by adopting the easy-to-manufacture wear-resistant rolling roller, the tungsten carbide coating is arranged on the surface of the rolling roller body, so that a tungsten carbide spraying finished product is formed on the surface of the rolling roller body, and after the tungsten carbide coating on the surface is dried, the tungsten carbide coating is hardened into super-hard spraying, thereby improving the wear resistance of the roller surface and prolonging the service life of the rolling roller body.

2. The wear-resistant calender roll easy to manufacture can reduce the phenomenon of surface slipping of the tungsten carbide coating through the round hole pressing groove, and when the calender roll body is used for a long time, the tungsten carbide coating on the surface of the calender roll body can generate heat, the excessive heat can influence the self quality of the tungsten carbide coating, and the round hole pressing groove can transfer and conduct heat to the heat on the surface of the tungsten carbide coating, so that the service life of the device is prolonged.
