In the scenario of magnetic stripe welding and cutting of PET, PVC, paper card, etc., the production scenario revolves around the magnetic stripe machine and its best running state. The magnetic stripe machine is the main component of the production system, and its seamless operation determines the effectiveness of the production system and the value of the product. The production system is manufactured in Shenzhen, China, and exported all over the world. It has the characteristics of servo drive, temperature control, and high automation. In order to enable overseas customers to give full play to the use value of the magnetic stripe machine, this paper identifies the main attributes of the machine from the three aspects of daily operation specifications, troubleshooting paths, and cost-reducing and efficiency-enhancing maintenance strategies, and provides more targeted operation and maintenance manuals.
Daily operation specification of magnetic stripe machine to avoid human error
The magnetic stripe machine is highly automated, and the daily automated and standardized process is an inevitable requirement for eliminating production uncertainty. This is triggered by the attributes of WHCP's "servo motor driven automatic feeding" and "precise temperature control," which must be matched by the compliance of the operation framework at all levels.
Before operating the machine, first check the machine operation logbook, and after confirming the operation record, the operator starts to check the machine. The operator checks whether the machine is powered on and whether the air source is normal. The operator checks whether the specifications of the production materials (such as PET, PVC, or paper cards) meet the production requirements and ensures that the materials do not run off so as to avoid poor welding or cutting. While considering the servo motor feeding mechanism is stuck, check whether the imported temperature probe is connected with the control module and whether the pressure regulating knob of the magnetic paving head is in the initial position. In standby mode, verify that the core components of the machine are within the line of sight.
Production requirements must be accurately matched with the parameter settings in the system. The magnetic stripe machine adopts a servo motor for automatic feeding, and the speed, feeding, and length can be adjusted. The operator enters accurate parameters into the control system according to the magnetic stripe specifications and material characteristics. For example, PVC material is thicker, so the feeding speed needs to be reduced to ensure the magnetic strip is flat. For cutting short magnetic strips, the feeding length parameter of the servo motor needs to be repeatedly calibrated to avoid cutting deviation. The temperature setting needs to adopt an imported temperature control module, and the heating temperature is set according to the welding requirements of the magnetic strip. Generally, the welding temperature of PET material needs to be adjusted and controlled at 180-220℃, and the welding temperature of PVC material needs to be adjusted at 160-200℃. After the temperature is set, observe the temperature display screen, and start the operation after the temperature is stable.
The equipment must be monitored in real time during operation. The operator should actively supervise the running state of the feeding mechanism. Ensure that the PET, PVC, or paper card and related materials being conveyed run smoothly, without any skewing or jamming. Also check whether there are bubbles or false welding at the welding place and whether there are burrs or uneven lengths at the cutting place of the magnetic strip. If any abnormal situation occurs, the best way is to press the emergency stop button to prevent the possibility of upgrading the fault. After production, the power and air supply of the equipment should be cut off, the residual waste on the feeding mechanism of the equipment should be cleaned up, and the equipment operation record should be filled in.
Troubleshooting of common faults of magnetic stripe machines
In long-term production, the magnetic stripe machine may expose different fault causes. The most serious problems reported by overseas customers are poor welding and inaccurate cutting. In view of the features of the equipment, such as "magnetic head temperature and pressure can be adjusted separately" and "accurate cutting," the following methods can be adopted to accurately solve the concerns of troubleshooting:
Poor welding quality is common, especially in the case of loose connection between the magnetic stripe and PET, PVC, or paper card; air bubbles; or false welding. At this time, first check the temperature setting of the magnetic stripe head, check the real-time feedback of the imported temperature probe, and see if it is within the standard temperature setting range. If the temperature is low, it needs to be reasonably increased through the control module; if the temperature is within the normal range, check the pressure parameters of the corresponding magnetic stripe head, because the device supports the individual adjustment of the pressure of a single magnetic stripe head. For areas with poor welding, the pressure knob can be adjusted appropriately. Generally, the pressure should be controlled at 0.3-0.5 MPa to ensure the magnetic strip is closely attached to the substrate. In addition, check whether the heating tube is aging and damaged. Uneven heating of the welding heating tube can also lead to poor welding. At this time, the heating tube of the same model needs to be replaced.
Another common problem is inaccurate magnetic stripe cut length. Troubleshooting should begin with the servo feed mechanism. Here, worn feed rollers can be repaired or compensated for by different roller pressures, and then the length feed parameters are adjusted by the servo motor in the system control. Length calibration requires several trial cuts. The appearance of burrs on the edge also indicates that the blade needs to be checked. The worn blade needs to be replaced, and the pressure and speed parameters need to be adjusted to stabilize the cutting mechanism and improve efficiency.
In addition to these two types of faults, the equipment may also experience material jamming. At this time, check whether there are foreign objects blocking the feeding channel. After cleaning the channel, check the running status of the servo motor. If the motor makes abnormal noises when running, it may be that the motor bearing is worn or the circuit is in poor contact, and professional maintenance is required.
Regular maintenance of Magnetic Stripe Machine
As a high-precision production equipment, the magnetic stripe machine needs service and maintenance to ensure the continuous production of overseas customers. As the equipment has the characteristics of "high automation" and "wide adaptability," it is reasonable to build a "daily + regular" maintenance framework and form a "daily + regular" maintenance system. The specific practices are as follows.
It is essential to incorporate daily maintenance into the workflow. At the end of each production day, wipe the machine surface and key components, including the magnetic placement head, feeding mechanism, etc., with a dry cloth. Ensure that no operating waste or dust accumulates. When cleaning the surface of the inlet temperature probe, pay attention to the high temperature detection sensitivity. Wipe carefully to ensure and improve accuracy. Moving parts such as the paper feed roller and cutting mechanism need lubricating oil to reduce mechanical wear. Also check whether the circuit connections and air pipes are firm, and deal with loose and aging phenomena to reduce risks.
In daily maintenance, the key components should be checked. Pay attention to the working temperature and abnormal noise of the servo motor. Ensure the integrity of the motor operation, and use a multimeter to check the insulation performance. Judge the insulation of the heating tube and check whether the parameters of the temperature control module are stable. The parameter drift should be recalibrated. Check the spring force of the head pressure spring. If the elasticity of the spring is reduced, the spring must be replaced to accurately adjust the pressure.
A thorough maintenance should be carried out every month. For this, the feeding mechanism and cutting mechanism should be disassembled, and the residual waste and oil stains should be wiped off. Check gears, bearings, and any parts that show wear and replace them as needed. It is also important to install revised and updated control system firmware. Safety protection features, such as emergency stop buttons, should also be tested.
