Detailed introduction

Paper machine guide rolls are categorized into blanket guide rolls and web guide rolls in terms of application. The application parts include pressing, drying, curling, rewinding and other parts. The guide rolls used in the net and press sections are generally covered with rubber. The guide rolls used in the drying section are called transmission guide rolls, which are generally not covered with rubber and are thicker than ordinary guide rolls. Fabric conduit, net guide roller, paper guide roller, chrome rollers, etc. all over the paper machine before and after. The guide rolls guide and drive the screens and felts in the wet end and dry section of the paper machine. The same bearings are used for the guide rolls in both areas. However, different lubrication and seals are used depending on the application location. In older paper machines, the wet end section was often lubricated with grease and the drying section with oil. In modern paper machines, both sections are lubricated with oil circulation. Due to the different working conditions, the wet end and dry section need to use their own oil circulation lubrication.
1. The whole guide roll consists of roll core, support, stopper, roll and bearing connection. 
2. the roll rotates through the bearing and roll core, which reduces rolling friction and rolling resistance, prolongs the service life of the guide roll, facilitates the post-processing of the steel pipe, and improves the processing efficiency.
3. The surface of the roll is concave curved surface, so that the steel pipe is automatically centered on the roll, and the folding plate can be set to limit and fix the steel pipe to prevent the steel pipe from leaving the roll.
