Winding machine manufacturers: hardware characteristics of protection devices

Winding machine manufacturers: the hardware characteristics of the protection device! Vacuz machinery and equipment and everyone to see together!

In this project, the logic control chip receives the input signal feedback from the sensor and outputs the corresponding control signal to the relay control module according to the feedback signal, thus reducing the winding speed. The logic control chip 74LS21P meets the control requirements of the project. The logic control chip 74LS21 consists of two sets of 4 inputs and gates (positive logic). Typical values of its main electrical characteristics are: tPLH8ns, TPHL10ns, PD9MW2. Relay Module Automatic Winding Machine The electromagnetic relay used in this project consists of core, coil, armature, contact reeds, etc. As long as the voltage is at both ends of the coil, the coil current will flow through a certain, generating an electromagnetic effect, the armature will be attracted to the core by the electromagnetic force, overcoming the pull of the reset spring On the armature, the dynamic and static contacts (normally open contacts) of the armature are pulled together. When the coil is disconnected, the electromagnetic attraction decreases and disappears, and the armature returns to its original position under the reaction force of the spring, so that the moving contact and the original static contact (normally closed contact) are released.

This allows the circuit to be turned on and off. The normally open contacts and normally closed contacts of a relay can be distinguished as follows: the static contact that breaks when the relay coil is not energized is called a normally open contact; the static contact in the conductive state is called a normally closed contact. Relays generally have two circuits, namely the low-voltage control circuit and the high-voltage working circuit as a circuit. When there is no voltage or insufficient voltage at both ends of the relay coil, the common end of the relay (COM) is connected to the normally closed end (NC). When the voltage between the relay coils reaches saturation, the common terminal (COM) of the relay is connected to the common terminal (NO).

What should I pay attention to for the maintenance of the automatic winding machine? Targeted maintenance of the winding machine is very important. Its importance and necessity is reflected in the fact that the winding machine is a precision device. Regular maintenance is important. Correct use and reasonable maintenance can ensure the service life of the automatic winding machine equipment and reduce the failure rate.

1. Automatic winding machine equipment is fast and the quality of winding is stable. Automatic winding machine equipment has been widely used in the production and application of conventional electronic coils. Any kind of equipment is inseparable from the maintenance. This is especially important for automatic winding machine. Many parts of the equipment are fragile and require regular maintenance and repair to maximize efficiency.

2. Automatic winding machine equipment in the maintenance process should follow the wearing parts – electrical parts – mechanical parts of the maintenance process. Wearable parts are mainly friction, rolling and stress during the operation of the equipment. Parts, usually the manufacturer will indicate the wearing parts; maintenance of electrical parts is mainly to remove dust, check the heat dissipation holes, and check whether the electrical interface is effectively connected. Mechanical parts should be tightened during routine maintenance. The connection of each part lubricates the rotating and moving parts of the bearings.

3. Whether the automatic winding machine equipment can play an effective role, first of all, the correct use, and then to keep up with the maintenance work. Therefore, manufacturers must strictly follow the routine maintenance of automatic wire winding machine.
