Large-mesh device of spinning machine

Abstract

The invention discloses a large-mesh device of a spinning machine. The large-mesh device comprises a warp-feeding swing arm, a main warp-feeding roller and a switching off cam, wherein the switching off cam is arranged nearby the warp-feeding swing arm; a switching off cam base is arranged on the bottom of the switching off cam; the main warp-feeding roller is arranged above the switching off cam; a switching off wedge block is arranged nearby the main warp-feeding roller; a main net-rolling roller is arranged on the other side of the warp-feeding swing arm; a check grooved pulley is arranged on the main net-rolling roller; a chain wheel is arranged in the check grooved pulley; a net-rolling clutch is arranged outside the main net-rolling roller. Due to the fact that the main warp-feeding roller and the net-rolling clutch are arranged, the using efficiency of the spinning machine is higher, the machining error of the spinning machine can be overcome, the machining precision of the spinning machine is guaranteed, the net-rolling number can be increased, the machining action of the spinning machine is precise, and the yield is well improved.

Description

technical field [0001] The invention relates to a matching device for a textile machine, in particular to a large mesh device for a textile machine. Background technique [0002] When the weaving machine weaves the net, if the mesh requirement is large, the weaving machine needs to be modified. In theory, the formation of the net knot is the coordinated action of the three main parts of the upper hook, the lower hook and the orifice plate, supplemented by the feeder. It is formed by the action of the warp and net rolling mechanism. Generally, every time the main shaft rotates, the three main components coordinate once. The amount has a lot to do with it. The larger the let-off amount, the larger the volume of the net roll, and the larger the corresponding mesh. Traditionally, the warp let-off and winding net are driven by the corresponding cam to drive the pivot point of the let-off swing arm to swing. One end of the warp let-off swing arm is hinged to the connecting rod, a...

Traditionally, the warp let-off and winding net are driven by the corresponding cam to drive the pivot point of the let-off swing arm to swing. One end of the warp let-off swing arm is hinged to the connecting rod, and the other end of the connecting rod is hinged to the clutch. The swing of the warp let-off swing affects the connecting rod to drive the clutch to rotate. , the clutch is assembled on the shaft head of the main let-off roller and the main net roll, and the rotation of the clutch drives the rotation of the main let-off roller and the main net roll, so as to realize the let-off and web winding. The traditional measure of enlarging the mesh is only to increase The stroke of the winding cam increases the amount of warp let-off and winding, but it is often impossible to weave larger meshes due to the limitation of the technical performance of the machine
