Description

Technical Field

[0001] This utility model relates to the field of papermaking machine technology, specifically to a cordless paper feeding system for papermaking machines. Background Technology

[0002] Paper is a sheet-like fibrous product used for writing, printing, painting, or packaging. It is generally made from an aqueous suspension of plant fibers that have undergone pulping, which are then interwoven, initially dehydrated, compressed, and dried.

[0003] Traditional paper feeding in papermaking machines generally employs three methods: manual feeding, rope feeding, and cordless feeding. Manual feeding is labor-intensive, slow, and costly, and also poses safety hazards. Rope feeding is typically used in low- to medium-speed paper machines, but the feeding rope is prone to detachment during operation, suffers severe wear, and paper breakage due to speed differences. Cordless feeding is currently more widely used and can now be employed in high-speed paper machines.

[0004] Currently, when paper is produced using paper guide ropes, workers need to fix the paper guide ropes to the paper tail. Due to severe wear of the paper guide ropes, the paper guide strips are prone to breakage, increasing the frequency of maintenance, affecting the stability of the papermaking machine and the quality of the products, and reducing the efficiency of production.
