In the modern textile industry, especially for high-precision equipment such as the TMT winding machine 12-head spinning equipment, it is crucial to choose the right curled paper tube. This paper tube not only needs to have sufficient strength to withstand the tension and pressure during high-speed operation, but also needs to maintain a certain flexibility to adapt to different types of fiber materials.1. Basic structure of curled paper tubeCurled paper tubes are usually made of multiple layers of high-strength paperboard through spiral curling, bonding and pressing. Each layer of paperboard is fixed with high-performance glue to form a solid overall structure. In order to achieve specific mechanical performance requirements, manufacturers will adjust the thickness, number of layers and type of adhesive during the production process. For the curled paper tube used in the TMT winding machine 12-head spinning equipment, the single size is 110124150 mm, and it needs to have a compressive strength of 1800-2000 Newtons (N), which requires the paper tube to have extremely high structural stability.2. Realization of high strength: selection of materials and processesIn order to ensure that the curled paper tube can withstand the huge tension caused by the high-speed operation of the TMT winding machine, the selection of high-quality raw materials is the key. First of all, the choice of paper is crucial. High-strength kraft paper is the preferred material due to its excellent tensile strength and tear resistance. In addition, some manufacturers will add glass fiber or carbon fiber reinforcement to further enhance the overall strength of the paper tube.In addition to high-quality paper, the choice of adhesive also directly affects the strength of the curled paper tube. High-performance environmentally friendly hot melt adhesive is widely used in paper tube manufacturing. It can not only cure quickly in a short time, but also provide strong bonding force to ensure that each layer of paper is tightly combined to avoid stratification. At the same time, advanced gluing technology can ensure uniform distribution of glue, thereby improving the compression resistance of the paper tube.3. Design of flexibility: meeting the needs of fine denier tailsAlthough high strength is one of the important indicators of curled paper tubes, flexibility cannot be ignored in practical applications. Especially when dealing with fine denier tails, moderate flexibility can help reduce the risk of fiber breakage and improve production continuity and efficiency. To this end, manufacturers use a special curling process to give the paper tube a certain degree of elasticity while ensuring sufficient strength.For example, the curled paper tube used on the TMT winding machine is designed with a reverse wire groove and a pressure point structure. The design of the reverse wire groove helps to guide the fiber to be evenly distributed and prevent the problem of broken wire caused by uneven winding; while the pressure point increases the friction on the surface of the paper tube, making it easier for the fiber to adhere to its surface and reducing the possibility of sliding. These detailed designs not only improve the flexibility of the paper tube, but also significantly improve the performance during the unwinding process, and are particularly suitable for the treatment of fine denier wire tails.4. Production processThe production process of curled paper tube includes multiple steps, and each link needs to be strictly controlled to ensure the quality of the final product. The first is the material selection stage, in which paper of appropriate thickness and density is selected according to the product specification requirements. The next step is the cutting process, in which the large roll of paper is cut into small rolls of the required width. Then enter the curling section, and the small rolls of paper are stacked layer by layer at a predetermined angle through special equipment and appropriate pressure is applied to make the paper fit tightly to form a tubular structure.In the curling process, the application of glue is crucial. Precisely controlling the amount of glue and coating speed can ensure a firm connection between the papers while preventing excessive glue from causing the paper tube to become too heavy or hardened. The last step is to inspect the finished product, including appearance inspection, dimensional measurement, and mechanical property testing, to ensure that each paper tube meets the use standards.In short, through scientific and reasonable material selection, sophisticated processing technology, and humanized design, the curled paper tube has successfully achieved a perfect combination of high strength and flexibility, providing a reliable solution for high-end textile equipment such as TMT winding machines. This not only improves production efficiency, but also contributes to the sustainable development of the industry.
