Description

Technical Field

[0001] The invention belongs to special equipment for the papermaking industry, and in particular relates to a device suitable for replacing manual work of wrapping the circumference of a paper roll with a transparent tape on a paper roll conveying production line of a papermaking enterprise. Background Art

[0002] The paper rolls produced by the paper machine are packed and put into storage warehouses. In order to prevent moisture and humidity during storage and transportation, prevent mosquitoes from entering the paper rolls, keep the paper rolls clean and hygienic, and not affect subsequent processing and use, the paper rolls are usually packed with coated kraft paper first, and the end faces of the paper rolls are covered and pressed with inner and outer seals. After the paper rolls are packed by the universal coated kraft paper packaging machine, there will be a certain gap between the folds and the outer seals, and it cannot be guaranteed to be completely sealed. At present, some paper mills with high requirements for paper roll quality usually use transparent tape to wrap the paper roll edge protection work. The general operation process is: the paper roll is transported to the tape sticking station by the chain conveyor and stops in the middle of the driving roller. The chain conveyor descends and the paper roll falls on the driving roller; the appropriate transparent tape is manually selected and pasted on the circumferential edge protection of the paper roll, the driving roller is started, and the tape roll is manually released at the same time, and the transparent tape is pasted on the circumferential edge protection of the paper roll. The side tape is manually smoothed and pasted on the outer head of the end face of the paper roll to meet the sealing performance requirements, and the transparent tape is manually cut off. According to 80 paper rolls per hour per production line, each paper roll needs to be pasted with circumferential edge protection on both sides, and one shift works for 8 hours. 2 operators in each shift respectively paste the tape on the circumferential edge protection on both sides. Each operator needs to complete the pasting of 640 circumferential edge protections per shift. The work intensity is high and the actions are repetitive and single. For enterprises, the annual labor cost is huge. Summary of the invention
