Description

Technical Field

[0001] This application relates to the technical field of web packaging equipment, and specifically relates to a labeling device for web paper. Background Art

[0002] The general production process of the rear section of web paper in a paper mill is that the rewinder receives the pressed original paper roll, and cuts and processes the original paper roll according to the specifications required by customers (such as diameter, width), generating web papers of specific specifications. Before these finished web papers of different varieties, grammages, grades, specifications, etc. are packaged and stored in the warehouse, they must be able to withstand packaging, storage, transportation, and other related processes, and the production information of the finished web papers must be accurately and timely entered into the computer to facilitate the confirmation by the finished product department and the understanding of the inventory by the sales department. All these tasks must be completed by a web packaging machine. A web packaging machine is a device used for packaging web paper, mainly for operations such as surface coating and labeling of the rolled paper.

[0003] In the labeling operation link, the traditional operation is that the computer system prints out the information of the web paper to be labeled, and the operator takes it out manually and pastes it on the side of the web. One conveyor line requires one connected computer, one printer, and one operator. This operation method cannot achieve full automation, and the operator is working near the conveyor line for a long time, which poses a safety hazard. During the operation, the operator cannot leave, otherwise the web paper will be congested on the conveyor line. In addition, there are also problems such as slow operation speed, which in turn affects the shipping speed of the entire production line. Summary of the Invention
