This focuses on square pipe bundling equipment for automatic collection and packing at the end of welded pipe production lines, suitable for square and rectangular tubes. The machine automatically arranges and stacks single tubes into neat square bundles, then conveys them to the binding station for manual or mechanical fastening, followed by hoisting and storage. Compared with manual stacking, this equipment significantly reduces labor demand, lowers manual intensity, improves packing efficiency, and cuts overall production costs. With stable operation and simple control, it ensures consistent bundle shape and orderly arrangement, supporting smooth post-production handling and standardized logistics. Designed for continuous tube manufacturing, it serves as a reliable end-of-line solution to streamline workflow, enhance productivity, and optimize packing management for metal pipe production.
