Description

Technical Field

[0001] The utility model relates to the technical field of paper machines, in particular to a synchronous pulley mounting structure. Background Art

[0002] The cutting arm of a paper machine is an important component in the paper machine, mainly used for cutting the continuously produced paper according to certain specifications and lengths. It usually consists of a mechanical structure, a driving device, and a cutting tool. The mechanical structure ensures that the cutting arm can move stably on a specific track or guiding device; the driving device provides power for the movement of the cutting arm, enabling it to accurately synchronize with the traveling speed of the paper and perform cutting operations at the required positions; the cutting tool directly acts on the paper to achieve the cutting action. The performance and accuracy of the cutting arm play a crucial role in ensuring the cutting quality, dimensional accuracy, and production efficiency of the paper.

[0003] The synchronous pulley for the cutting arm of a paper machine is a key component for driving the movement of the cutting arm. It cooperates with a synchronous belt to transfer power from a driving source (such as a motor) to the cutting arm, achieving precise linear or rotational motion to ensure that the cutting arm can synchronize with the running speed of the paper machine and accurately cut the paper at the specified position. In some existing large-scale and high-speed paper machines, two cutting arms are equipped to improve production efficiency and cutting accuracy. Multiple cutting arms require two driving sources or isochronous synchronous pulleys for driving. Using two driving sources results in a relatively high input cost, and using isochronous synchronous pulleys has poor flexibility. In actual production, due to changes in the characteristics of the paper, adjustments in the production process, or differences in cutting requirements for different parts, some cutting arms may need to have different speeds or motion modes, and isochronous synchronous pulleys cannot meet this flexibility requirement.
