For products such as posters, learning cards, and EVA, the learning card paper rolling machine is the main mechanical equipment. The stability of the learning card paper rolling machine determines the quality of the product and the efficiency of production. The paper rolling machine provides a solution to the problem of manual paper rolling. Manual winding is inefficient, costly, and inaccurate, resulting in wrinkled products that are not esthetically pleasing. The professional learning card paper winding machine has a high degree of automation and precise control, which is a solution to the problem of manual winding. This article records the precautions for the learning card paper winding machine and provides professional operation guidance for overseas customers. Based on my understanding of the manufacturing of the paper winding machine, its products are sold all over the world.
The adaptability of the learning card roll paper machine is its strength. This versatility includes a wide range of substrates, such as printing and packaging papers, plastics, and composite structures. However, the physical properties of these materials can vary greatly. Adequate preparation, such as a period of acclimatization and pre-operation equipment checks, will help to avoid failures.
Material adaptability depends on the flexibility of the substrate type and equipment parameters. For paper materials, mainly printing and packaging paper, the key consideration is the weight of the paper. For regular learning card paper in the range of 80-120 g, the take-up tension should be set to the medium range to avoid tearing of the paper due to excessive tension. For plastic films and composite materials with smooth surfaces and high ductility, anti-slip devices must be installed on the equipment, and oil stains and impurities on the surface must be cleaned up due to misalignment and increased winding tension during the winding process. In addition, if multi-material winding is required at the same time, the width and thickness deviation of the material should be controlled within ±0.5 mm so that the equipment can realize the multi-material winding function.
During the inspection, both the mechanical and electrical control systems must be considered. From the mechanical aspect, the parallelism of the winding roller should be checked. If there is any deviation, the roller shaft bracket should be adjusted to minimize the winding stress difference. At the same time, mechanical wear should be handled in a timely manner, and lubricating oil should be added to the transmission gears, chains, and other parts that need lubrication in a timely manner. The electrical control system should ensure the sensitivity of the touch screen parameter settings and confirm the running status of the efficient automation module. For example, the system must operate normally to automatically adjust the tension and issue a fracture alarm to avoid electrical shutdown. Automation module downtime issues must be managed to avoid operational electrical control failures.
The operation of the learning card roll paper machine requires precise control to ensure the quality of the product. Under standard operating conditions, the simple and efficient advantages of the machine can be fully utilized, and human errors can be avoided.
When adjusting the settings, the principle of "matching material characteristics" should be followed first. For example, the coated paper commonly used for learning cards is recommended to have a lower paper collection speed of 8-12 m/min. If the speed is too fast, wrinkles will easily occur. For flexible EVA, it is recommended that the material tension be set to 5-8 N. Due to the advanced system of the equipment, the tension and winding parameters can be adjusted and monitored in real time to achieve uniform winding. When changing products of different specifications, the memory function of the equipment can be used to call out the corresponding setting parameters. This reflects the humanized design of the equipment, avoiding the time loss caused by unnecessary adjustments. Finally, for single or multiple sheet winding, especially multiple sheet winding, automatic synchronous deviation control should be enabled to maintain proper stacking alignment, and checking the material distribution is crucial for proper multiple sheet winding.
Even the simplest machinery requires operator training. During operation, the unwinding work and problems such as uneven edges and wrinkles are automatically adjusted in real time through the touch screen, without manual intervention in the equipment. Each component of the automated system is designed to allow the equipment to run for long periods of time without interruption, but qualified personnel must check the system periphery every 30 minutes to avoid raw material or finished product depletion or mechanical imbalance. They must verify the perimeter, the audibility of the equipment, and the margins of the materials. Finally, for safety reasons, the equipment must be shut down before any interlocked safety doors can be opened.
The overall reliability and life of the learning card roll paper machine depend on the efficiency of the planned maintenance performed after the production run is completed, and the reduction of equipment downtime can improve the utilization rate.
Maintenance, daily cleaning, and routine maintenance should be planned. After the daily operation, the power supply should be cut off, and the paper scraps, dust, and other things on the surface of the equipment should be cleaned. In particular, the surface of the take-up roller should be wiped clean with a soft cloth to avoid the residual impurities affecting the take-up accuracy when used next time. For the control box of the equipment, the internal dust should be cleaned regularly to avoid short circuits caused by dust accumulation. At least once a month. Dust removal should also be carried out during routine quarterly maintenance, along with revisions to the dust box control and wear checks on the winding rollers, which should be the main focus of external maintenance activities. If the surface of the roller is scratched, it should be polished. Also, check the oil pressure of the hydraulic system to ensure that the control accuracy of the equipment is not affected. In addition, the automation module of the equipment should be adjusted to ensure the normal operation of automatic alarms, automatic shutdowns, and other functions.
To be handled effectively, common fault diagnosis must be combined with the specific attributes of the equipment. When diagnosing the fault of uneven winding material, first verify whether the tension sensor is faulty. If the sensor is defective, it must be replaced. If the winding speed suddenly drops, the root cause may be the wear of the transmission system. At this time, the gears, chains, and their meshing should be checked, and corresponding lubrication should be carried out. The equipment control panel displays the fault code. By referring to the code in the code manual, the operator can identify the fault and thus the equipment. This design highlights the system's operational simplicity, allowing even novice operators to quickly troubleshoot basic faulty equipment.
