rise and fall device of needle bar for a double raschel machine

摘要

The subject innovation relates to a needle bar lifting device for the double ratsel machine.; More specifically the immobilized mounted on the upper surface needle bar cam and a link, and the mounting by keeping the angle of the third angle to the bottom surface of the needle bar lifting frame to be raised and lowered by a rod connected to the link, the needle bar lifting frame 3 of the post, as soon the vertical bearings to derive the three posts are inserted stable lifting consists of a fixed frame which at the same time to house the needle fixedly mounted on the front end guided to a lifting in a stable manner.; In accordance with this the present design by the above arrangement, there is a post for guiding the lifting of the lifting frame are three installed to operate yirumyeonseo 3 each in at least three parts: the front end of the fixed frame when the lifting frame is raised and lowered by a rod cooperating with the cam do not have a mounting leaning phenomenon toward the fixed needle case when very stable and can be elevated with, so that the needle bar and the needle work mounted on the lifting frame in the needle case mounted to the front end of the fixed frame is thereby minimizing the friction and the load as the prevention of wear and deformation of the needle case sikimyeo screen equipment the service life of the needle case and needles, according to the characteristics such that a smooth knit, from a thin cloth as be the place exactly knitting a thick fabric with double the needle bar platform to provide value for ratsel machine.
