Description

Technical Field

[0001] The present application relates to a yarn tail processor. Background Art

The moving part of the present application adopts two settings, one is a clamping method, that is, a groove is provided, and the groove is clamped and connected with the external track; the second is to adopt the form of setting a baffle, the purpose of the baffle is first to limit the position, and secondly to generate friction with the track to prevent the moving wheel from easily falling off the track.

[0007] Preferably, a connecting bearing is provided between the moving wheel and the wheel axle.

[0008] Preferably, the shearing portion comprises a shearing bracket and a shearing knife fixedly connected to the shearing bracket, and the shearing knife is designed to be a straight line to form a power member.
