As an indispensable winding carrier in the chemical fiber production process, the standardized operation of chemical fiber paper tubes directly affects production continuity, product quality, and equipment safety. Given that the use of paper tubes involves multiple stages such as loading, unloading, installation, and storage, establishing standardized operating procedures is crucial for improving production line efficiency.
During the loading and unloading of paper tubes, dedicated clamps or robotic arms matched with the winding equipment should be used preferentially to avoid manual handling that could cause bumps or deformation of the tubes. During loading and unloading, movements must be smooth, avoiding single-point force or tilting dragging to prevent hidden cracks in the tube wall. The stacking height should be controlled within five layers, with anti-slip cardboard padding between layers to prevent the bottom layer from tipping over due to pressure. For paper tubes coated with moisture-proof or anti-static layers, contact with sharp objects should be avoided to prevent damage to the coating and affecting subsequent performance.
Appearance and dimensional verification must be performed before installation on the machine. First, visually inspect the tube for obvious dents, delamination, or uneven end faces. Then, use calipers to check the wall thickness and roundness, ensuring the deviation is within the equipment's allowable range (generally roundness ≤ 0.1mm, wall thickness error < 0.05mm). During installation, accurately embed the paper tube into the winder's air shaft or mechanical chuck, ensuring the axis is coaxial with the equipment's rotation center. Then, slowly inflate or tighten, confirming even distribution of clamping force before starting the winding program. Never operate at high speed before the tube is fully secured, as this could cause the paper tube to detach and lead to a safety accident.
During operation, monitor the matching status between the paper tube and the yarn cake. If abnormal fluctuations in winding tension or chrysanthemum-like loosening of the yarn cake end face are observed, immediately stop the machine and check for changes in the paper tube's concentricity and surface friction. If necessary, replace with a new tube to eliminate the interference. During production breaks or batch changes, unused paper tubes should be placed in a constant temperature and humidity storage area (temperature 20±2℃, relative humidity 50%±5%) to prevent drastic environmental changes that could lead to moisture absorption, deformation, or embrittlement.
During downtime maintenance, residual fibers and oil stains on the paper tubes should be cleaned, and the clamping parts should be inspected for wear and lubricated regularly to ensure accurate positioning for the next machine run. Waste paper tubes must be collected according to recyclable materials to avoid mixing with non-degradable debris, thus facilitating resource recycling.
In summary, although the operation of chemical fiber paper tubes is an auxiliary process, it is integral to the entire production chain. Only by strictly adhering to the standards for loading, unloading, verification, installation, monitoring, and storage can their stable load-bearing capacity during high-speed winding be maximized, providing a reliable guarantee for improving the quality and efficiency of chemical fiber manufacturing.
