Sinker bed motion control cam

Abstract

The invention belongs to the technical field of warp knitting members and in particular relates to a sinker bed movement control cam for a multi-bar warp knitting machine. The sinker bed movement control cam comprises a wheel disk and a shaft neck integrated with the wheel disk, wherein the shaft neck is connected with a cam shaft, an external movement circular curve for controlling circulation movement of a groove pin bed is arranged at the periphery of the wheel disk, an internal movement circular curve is arranged on the other side, relative to the shaft neck, of the wheel disk, and the external movement circular curve and the internal movement circular curve are in conjugation. The external movement circular curve is formed by a sinker bed lowest point pause stage, a low speed rising stage, a sinker bed highest point pause stage and a low speed descending stage. The internal movement circular curve is also formed by a sinker bed lowest point pause stage, a low speed rising stage, a sinker bed highest point pause stage and a low speed descending stage. The sinker bed lowest point pause stage is larger than the sinker bed highest point pause stage, and the low speed rising stage is larger than the low speed descending stage. The cam is compact in structure, resisting to abrasion, stable in transmission, capable of improving knitting stability of the machine and capable of improving the quality of knitted fabrics.

Description

technical field [0001] The invention belongs to the technical field of warp knitting machine components, in particular to a sinker bed motion control cam of a multi-bar warp knitting machine. Background technique [0002] The transmission mechanism is an important component of the warp knitting machine. The transmission mechanism takes the main shaft as the main body. Through various transmission parts such as cams, eccentric connecting rods, and gears, the loop forming parts on the machine move according to the expected trajectory to realize The machine works in circles. The movement of the sinker bed is mainly controlled by the motion control cam of the sinker bed, but the existing cam structure design is unreasonable, easy to wear, loud noise, large inertia, unstable transmission, and there is a large impact during movement, which greatly reduces The weaving speed and stability of the machine are affected, and the processing and manufacturing are difficult, the accuracy ...
