Description

Technical Field

[0001] This utility model relates to the field of paper tube cutting technology, and more specifically, to a high-efficiency paper tube cutting and shaping device. Background Technology

[0002] Seamless paper tubes are cylindrical structures made of paper without any seams. They are widely used in packaging, textiles, printing, electronics, and machinery. Due to their advantages such as light weight, low cost, and recyclability, seamless paper tubes have important applications across various industries. Common applications include textile rolls, patterned printing rolls, and other packaging scenarios requiring precise measurement, cutting, and marking. The manufacturing process of seamless paper tubes typically involves steps such as gluing, winding, and pressing the paper. After forming the tube, certain post-processing steps, such as cutting and surface treatment, are required to ensure the quality and precision of the final product. Therefore, cutting technology plays a crucial role in the production of seamless paper tubes.
