Technical Field

[0001] The invention belongs to the field of cigarette production, and in particular relates to an automatic paper roll lifting device. Background Art

[0002] In cigarette production lines, paper rolls (such as cigarette paper, filter plug wrap, or packaging material) are typically stored in large rolls. When a roll of material is exhausted, it needs to be replaced.

[0003] Traditional paper roll handling methods mostly rely on manual operation or simple mechanical equipment assistance, which is not only inefficient but also poses high safety risks. Manual handling of paper rolls is labor-intensive due to their large size and weight. Furthermore, manual handling speed is limited by the worker's physical strength and operational proficiency, making it difficult to meet the demands of large-scale, high-efficiency production. At present, some simple mechanical equipment, such as paper roll handling forklifts and paper roll handling carts, have reduced the burden of manual handling to a certain extent. However, in the production process of papermaking and related industries, it is often necessary to accurately lift the paper roll to a specific height to connect with subsequent processing equipment such as unwinders, crimping machines, printing presses, etc.

[0004] However, existing equipment has difficulty in achieving precise lifting of paper rolls, making it inconvenient to install the paper rolls on subsequent processing equipment. Manual adjustments are required, which not only wastes time but also increases the workload of workers.

[0005] Therefore, we propose a paper roll automatic lifting device to solve the above problems. Summary of the Invention
