Apparatus for shearing thread end line of magnetic loop automatic threader

Abstract

A stub cutting device for a magnetic loop coil winding machine is arranged beside a truncated cone-shaped cavity on a base plate. The stub cutting device is characterized in that the stub cutting device comprises a fixed seat; one end of the fixed seat is provided with a longitudinal slot, and a plurality of threading holes communicated with the longitudinal slot are longitudinally arranged on the fixed seat; and a shaft hole passing through the longitudinal slot is laterally arranged on the fixed seat, a line cutting knife capable of rotating in the shaft hole is arranged inside the shaft hole, and a notch capable of cutting off lines passing through the threading holes when the line cutting knife rotates is arranged on line cutting knife corresponding to the longitudinal slot on the fixed seat. The stub cutting device is provided with the longitudinal slot on the front end of the fixed seat, a plurality of threading holes communicated with the longitudinal slot are longitudinally arranged on the fixed seat, the shaft hole passing through the longitudinal slot is laterally arranged on the fixed seat, the line cutting knife capable of rotating in the shaft hole is arranged inside the shaft hole, and the stub cutting device cuts off the lines through the notch of the line cutting knife matching with an inclined plane arranged on the inner edge of the longitudinal slot. The stubcutting device has the advantages of convenient and rapid operation, easy maintenance, simple structure and low cost.

Description

【Technical field】 [0001] The invention relates to a thread end cutting device of a magnetic winding machine, in particular to a thread end cutting device for cutting off the front end of the thread after the thread enters a conical concave cavity. 【Background technique】 [0002] The enameled wire wound on the magnetic ring is a very familiar product. Its working principle is to make a circular motion of the wire in the circular cavity, and wind the wire to the magnetic ring round by round. And when the wire is wound on the magnetic ring for a set number of turns, the head wire and the tail wire on the wound coil must be cut off. At present, there is only a device for cutting the tail thread on the magnetic winding machine, and there is no device for cutting the head thread, which makes the coil only cut off the tail thread after a certain set number of turns, which makes the wound coil The length of the tail thread can be controlled. After setting the reserved length of the...

Problems solved by technology

At present, there is only a device for cutting the tail thread on the magnetic winding machine, and there is no device for cutting the head thread, which makes the coil only cut off the tail thread after a certain set number of turns, which makes the wound coil The length of the tail thread can be controlled. After setting the reserved length of the tail thread to a certain value, the reserved length can be the same every time the tail thread is cut. The length is different, that is, waste of material, and another worker needs to cut it again, so that the reserved length of the head thread is the same
