Abstract

The invention discloses an open type automatic winding device for a soft magnetic strip. The automatic winding device is characterized by comprising a rack, a tension adjusting device, a meter counting device, a magnetic strip guiding device, a clamping and rotating device, a lifting device, a film covering device and a control device; the tension adjusting device and the meter counting device are installed on the back side of the right part of the rack; the magnetic strip guiding device is installed in the middle of the rack; the clamping and rotating device is installed at the left part of the rack; the lifting device is installed at the left part of the rack and below the clamping and rotating device; and the film covering device is installed at the left part of the rack. The automatic winding device is stable in overall operation and high in magnetic strip winding efficiency, mutual extrusion and friction between magnetic strips are reduced, magnetic strip clamping is avoided, a coil lifting device can drive a coil to ascend and descend at a constant speed, coil installation is facilitated, the tension adjusting device and the control device are matched with each other to freely adjust the tension, the situation that the magnetic strips are stretched and deformed or stacked and cannot be wound in time is prevented, and the film covering device can directly cover films on the magnetic strips after the magnetic strips are rolled.

AI Technical Summary

Problems solved by technology

At present, the common magnetic strip winding device has the following problems in actual use: 1. More than 90% of the magnetic strip production lines commonly used by domestic enterprises do not have a matching magnetic strip winding device that can satisfy automatic control. Magnetic stripe rewinding and unwinding in the coiling mode has high manual labor intensity and low production efficiency, which cannot meet the actual production needs of rapid and continuous magnetic stripes; The speed of the winding material, as the radius of the magnetic strip winding material continues to increase, the speed of the magnetic strip winding will continue to increase. At this time, the magnetic strip is easy to be stretched and deformed, and sometimes even broken; 3. Ordinary magnetic strip winding device is manually lifted and installed when the coil is installed. After the completion of magnetization, the coil is heavy and requires a hydraulic vehicle to unload the coil after magnetization. It is inconvenient to load and unload, and the manual labor intensity is increased during installation. When unloading, you need to use a hydraulic vehicle, which is easy to cause damage to the magnetic strip; 4. There is no coating device in the ordinary magnetic strip winding device, and the magnetic strip in the coil cannot be protected by coating after the magnetization is completed; 5. The tension control device in the ordinary magnetic strip winding device can only directly display the tension value, without a tension sensor, the tension control device cannot cooperate with the control device through the tension sensor, and adjust the operating parameters of the magnetic strip winding device in time according to the tension of the magnetic strip during operation 6. The ordinary magnetic strip winding device does not have an electromagnetic brake. Due to the inertia at the end of the magnetic strip winding or emergency stop, the coil cannot stop rotating in time, which may easily cause the magnetic strip to be stretched, deformed or broken.
