The invention belongs to the field of thread-cutting equipment, and is specifically an automatic thread-cutting equipment, including a bracket; the lower surface of the bracket is fixedly connected with a clamping plate, and the upper surface of the clamping plate is slidably connected with a thread-cutting mechanism. The thread cutting mechanism includes a guiding mechanism. The automatic wire trimming equipment is equipped with a guide plate. Since the guide plate is an arc structure, the cylindrical wire can be stuck on the upper surface of the guide plate. During the movement of the wire, the roller inside the fixed bar contacts the outer surface of the wire, and the wire The friction force on the outer surface is converted from sliding friction to rolling friction, the friction resistance is reduced, and the friction loss on the outer surface of the wire is reduced. Under the restriction of the guide plate and two fixing bars, the lower surface of the wire is positioned by three points , Gravity forces the wire to always stick to the upper surface of the guide plate, ensuring the smooth and continuous movement of the wire, which solves the problem that the traditional wire is easy to deviate before cutting.
