Let-off mechanism for warp knitting machine

Abstract

The invention relates to the field of spinning, and particularly discloses a let-off mechanism for a warp knitting machine. The let-off mechanism comprises a base, a fixed baffle, a guide roller, a rotating shaft and a top plate; a movable baffle is arranged on the other side, opposite to the fixed baffle, of the base; one end of the rotating shaft is rotationally connected with the fixed baffle through a bearing; the rotating shaft is fixedly connected with the bearing; a connector is coaxially and fixedly installed at the other end of the rotating shaft; a sliding supporting bearing is fixedly installed on the side wall, corresponding to the connector, of the movable baffle; and the movable baffle moves upwards in the axial direction of the rotating shaft, so that the connector slides in the sliding supporting bearing and penetrates through the movable baffle. The let-off mechanism enables warp yarns to be conveyed in an internal sealed environment, so that the pretreatment effects of dust removal and the like are guaranteed; and meanwhile, the movable baffle in the structure can be rapidly detached, and one end of the guide roller is exposed, so that the warp yarns can be conveniently installed from one side of the guide roller, an operator can rapidly operate, and potential safety hazards are reduced during installation.

Description

technical field [0001] The invention relates to the textile field, in particular to a let-off mechanism for a warp knitting machine. Background technique [0002] Using one or several groups of yarns arranged in parallel to form knitted fabrics on all the working needles of the warp feeding machine at the same time, this method is called warp knitting, and the fabric is called warp knitted fabric. The machine that finishes this kind of warp knitting is called warp knitting machine. [0003] The warp knitting machine is mainly composed of a knitting mechanism, a bar traverse mechanism, a let-off mechanism, a pulling and coiling mechanism and a transmission mechanism. The warp let-off mechanism makes the warp yarn pre-process the warp yarn in a relatively sealed environment during the delivery of the warp yarn, but it is very inconvenient to install the warp yarn in such a sealed environment, and it takes a long time to thread the yarn each time, and There are potential safe...

Problems solved by technology

The warp let-off mechanism makes the warp yarn pre-process the warp yarn in a relatively sealed environment during the delivery of the warp yarn, but it is very inconvenient to install the warp yarn in such a sealed environment, and it takes a long time to thread the yarn each time, and There are safety hazards in the operation process, therefore, it is necessary to improve the existing warp let-off mechanism
