Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1 to 3, the cam shedding device of the weaving machine comprises a shedding arm 1 and a shedding cam 2, wherein the middle part of the shedding arm 1 is hinged to a frame, the shedding cam 2 is rotatably connected to the frame, and the structures are all conventional structures. Specifically, the one end that open arm 1 is close to open cam 2 is provided with rotor structure 3, rotor structure 3 includes fixed axle 31, it is connected with runner 32 to rotate on the fixed axle 31, runner 32 is provided with threely, and three runner variation in size, and is provided with the interval between the adjacent runner, and one of them runner 32 contradicts open cam 2, fixed axle 31 fixed connection in open arm 1. Specifically, a through hole is formed in the opening arm 1, a thread is formed in the inner wall of the through hole, a thread is also formed in the fixing shaft 31, and the fixing shaft 31 is in threaded connection with the through hole.
