Description

A paper machine roll Technical Field

[0001] This utility model relates to the field of papermaking machine technology, and more specifically, to a papermaking machine roller. Background Technology

[0002] The complete set of equipment that links the pulp into paper webs is collectively called a paper machine. This includes main components such as the headbox, wire section, press section, dryer section, calender, winding machine, and drive system, as well as auxiliary systems such as steam, water, vacuum, lubrication, and heat recovery. During paper transport, the paper is typically dried by pressing or heating rollers to ensure proper drying.

[0003] In the papermaking process, existing papermaking machines typically use heating elements inside the heating rollers to heat and dry the paper. However, if these internal heating elements malfunction, the entire heating roller needs to be disassembled for repair, resulting in poor efficiency and high costs. Furthermore, when the paper is being dried and smoothed by the rollers, impurities easily accumulate on their surface. The cleanliness of the roller surface affects the smoothness and quality of the paper. Manual cleaning of the roller surface using cleaning cloths and other tools is inefficient, time-consuming, and labor-intensive. Finally, the rollers on papermaking machines are inconvenient to install and offer limited protection, allowing dust to easily settle on them and affect surface cleanliness. Summary of the Invention
