Manual winding machine is a key equipment for winding operation. The wire arrangement system plays a core role in ensuring uniform winding tension. This is directly related to the quality, electrical performance and service life of the wound coil. Its unique mechanical structure contains exquisite design concepts.
First of all, there is a common tension adjustment wheel structure. It is generally composed of a flexibly rotating roller and a matching spring or counterweight device. When the wire passes through the tension adjustment wheel, the spring or counterweight applies just the right pressure to the wire according to the preset tension value, so that the wire always maintains a stable and uniform tension during the winding process. For example, when winding the enameled wire required for fine electronic components, the tension requirements of different wire diameters can be accurately adapted by fine-tuning the elastic force of the spring.
The wire arrangement screw is another key structure. It is connected to the motor or manual rocker, and through precise thread transmission, it drives the wire arrangement frame to make linear reciprocating motion, so that the wire is evenly and neatly wound on the bobbin. The screw pitch is carefully designed to ensure that the spacing between each circle of wire is consistent, avoiding uneven density, thereby ensuring that the winding tension is evenly distributed and that local tension mutations will not be caused by disordered wiring.
The guide pulley group should not be ignored. It is composed of multiple smooth pulleys arranged at specific angles and spacings, which provide a stable guide path for the wire. During the winding process, the wire moves smoothly along the pulley group, and the friction is minimized, effectively preventing tension fluctuations caused by obstruction of the wire. At the same time, the material of the pulley is usually selected from wear-resistant and low-friction engineering plastics or ceramics to further optimize the guiding effect.
Another type is the wire pressing device. It is located at the position where the wire is about to be wound onto the spool. Through an adjustable pressure plate, the wire is gently pressed to prevent the wire from jumping up or loosening due to centrifugal force or other factors during high-speed winding, thereby maintaining a stable winding tension. Moreover, the pressure of the pressure plate can be flexibly adjusted according to factors such as wire diameter and winding speed.
Some high-end manual winding machines are equipped with tension feedback control systems. The winding tension is monitored in real time through sensors. Once the tension deviates from the set value, the system automatically adjusts the relevant mechanical structures, such as adjusting the pressure of the tension adjustment wheel or the speed of the wire arrangement screw, to ensure uniform and constant tension throughout the winding process.
In short, the wire arrangement system of the manual winding machine relies on these unique mechanical structures to cooperate with each other, ensuring uniform winding tension in many aspects, meeting the high-precision requirements of winding operations in different fields, and laying the foundation for the high-quality production of various coils.
