Description

Technical Field

[0001] The utility model relates to the technical field of tube products, in particular to a regenerated foam tube core. Background Art

[0002] Foam cores are used everywhere in our daily lives, from curled paper towels to heavy cables. However, traditional foam core manufacturing technology has some inherent disadvantages and limitations. First, traditional foam cores are usually made of a single material, such as plastic or paper products. These single-material cores may cause indentations or damage to the surface of the material when winding films or other materials. This means a decrease in production efficiency and product quality, and new solutions need to be found.

[0003] The main advantage of the traditional foam core is that it is simple and easy to manufacture, and the manufacturing process is relatively mature. However, its main disadvantage is that the core made of a single material cannot provide good support and protection for the rolled material, which can easily cause indentations or damage to the surface of the material. In addition, the traditional foam core is prone to stress concentration during the curling process, further exacerbating this problem.

[0004] At present, some new technologies are trying to solve this problem. For example, some new foam cores are beginning to use composite materials, such as a mixture of plastic and paper. These mixtures can provide better cushioning and protection. However, these new foam cores still have some problems in the production process, such as low production efficiency, high cost, large material waste, etc. At the same time, these cores may cause indentations or damage to the surface of the material when rolling up the film or other materials.

[0007] The paper tube core is used as a basic skeleton. The paper tube core adopts a cylindrical hollow tube structure. The interior of the paper tube core is formed by pressing multiple layers of paper, and the outer layer is coated with a wax layer.
