Description

Technical Field

[0001] The invention relates to a baling machine, and in particular to a coil baling device and method. Background Art

[0002] Flexible wires such as cables and water pipes need to be coiled after production, and then wrapped with plastic or radially bundled with steel or plastic belts for storage, handling and transportation. However, the coiling and bundling equipment currently used are usually semi-automatic coiling and bundling are all manual operations and can only be done one at a time, resulting in multiple people collaborating and multiple operations to bundle a coiled pipe, which is labor-intensive for workers, low production efficiency and high labor costs.

[0003] Steel straps and plastic straps are the most widely used baling materials today. Especially with the rise of the petrochemical industry after the 1950s, plastics have become the most widely used material, laying the foundation for the development of automatic plastic strapping machines. The most widely used automatic plastic strapping machines in the existing technology are mainly divided into two categories: semi-automatic baling machines and fully automatic baling machines.

[0004] Specifically, the semi-automatic baler uses manual belt feeding by workers, which can not only bundle the outer surface of materials such as cartons, but also radially bundle coiled materials. However, due to manual belt feeding, the production efficiency is low. The fully automatic baler uses automatic belt feeding, but during the belt feeding process, the machine cannot pass the plastic belt through the inner cylindrical surface of the coiled material like workers, so it can only bundle the outer surface of materials such as cartons. At the same time, these two types of plastic belt balers can still only bundle at one position at a time. Accordingly, the field urgently needs to make further improvements or improvements to better meet the higher requirements of modern coil baling technology in terms of operating efficiency and convenience. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a coil bundling device and method, which can coil and radially bundle the coiled material and can perform radial bundling at multiple locations, thereby completing the bundling operation of flexible wires at one time.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is:
