Why does the winding machine have safety protection devices

A winding machine is a device that wraps a linear object onto a specific workpiece, typically used for copper wire winding. Most electrical products require enameled copper wire (abbreviated as enameled wire) to be wound into inductance coils, which can be processed through one or more processes using a winding machine. For example, various motors, hollow cup motors, rotors, stators, pin inductors, chip inductors, transformers, solenoid valves, slot inductors, resistors, ignition coils, RFID, transformers, audio coils, IC card high and low frequency coils, focusing coils, and so on. The textile industry often uses cotton yarn, artificial fiber yarn, etc. to wind various yarn balls and blooms suitable for textile machines, which can also be processed using a winding machine.

The safety protection device system of the fully automatic winding machine manufacturer is based on the JG series circular winding machine design. After on-site inspection and conversation with operators, it was found that when workers operate this series of circular winding machines, they put the unwrapped iron core into three rolling wheels. The specific operation is to open the dovetail lock strip of the storage ring body, separate the movable section of the storage ring opening, and allow the center of the additional winding iron core to pass through the opening part of the winding ring; Then lock the lock strip and press the foot switch to rotate the wire storage ring. Its high speed can reach 700r/min, and the wire head in the winding iron core needs to be manually pulled to the other side during the process.

Due to the high speed of the winding machine, workers need to operate at a high speed due to the action of the bracelet. At this time, two types of finger injuries occur: ① the broken end of the enameled wire can be inserted into the finger, causing finger injury; ② The copper wire running at high speed can press on the fingers, causing minor skin injuries to the fingers or crushing the fingers in severe cases.

The safety protection device is a device that, when the operator's hand enters a hazardous area, the infrared light emitted by the reflector is reflected into the receiver. The infrared sensor feeds back the low voltage signal to the logic chip, and then the logic control chip outputs the control signal to the relay deceleration module through microcontroller or logic judgment based on the position of the input signal, so that resistors with different resistance values are connected in series into the foot speed control circuit, Furthermore, by changing the voltage ratio of the foot pedal device, the frequency of the winding machine frequency converter is reduced, achieving the effect of reducing the speed of the winding motor, ensuring the safety of the operator. Improper operation of textile operators can cause injuries, effectively improving the safety of the winding machines of fully automatic winding machine manufacturers.

The fully automatic winding machine manufacturer's winding machine is a specialized equipment used for winding various types of electromagnetic coils. According to the winding method, the winding machines can be divided into three categories: parallel winding machines, flying fork winding machines, and circular winding machines. Parallel winding machine is a winding machine that is driven by the main shaft to rotate the skeleton, and coordinates with the three-dimensional mechanism to move and position the enameled wire in a spiral arrangement on the outer layer of the skeleton. It is usually used for transformers, inductors, and other coils. When the flying fork winding machine is used for winding, the framework is fixed and the side spindle drives the flying fork to rotate to wrap the enameled wire on the outer groove of the framework. It is usually used for motor rotors and cross instrument coils. The circular winding machine is a machine that uses a guide needle to pull the enameled wire in a reciprocating linear motion, and rotates it in conjunction with the skeleton to wind the enameled wire on the inner ring groove of the skeleton. It is usually used for motor stators and special products.
