Aramid yarn two-for-one twisting mechanism with automatic yarn clamping function

Abstract

The utility model discloses an aramid fiber yarn two-for-one twisting mechanism with an automatic yarn clamping function, which belongs to the field of aramid fiber yarn two-for-one twisting mechanisms, and comprises a rack and an arranged automatic yarn clamping mechanism, when equipment breaks down to cause the springback phenomenon of yarns, an air cylinder drives an output end to drive an extrusion block to move backwards, and the automatic yarn clamping mechanism is used for clamping the yarns. The extrusion blocks no longer extrude the pressed blocks in the two side directions, after the compression springs on the fixing rods conduct stretching recovery operation, the connecting plates are pushed in the opposite directions, the connecting plates move along the fixing rods through the connecting holes in the side walls, and at the moment, the symmetrical wire clamping plates conduct synchronous relative movement operation and are matched with the wire clamping grooves formed in the opposite face walls, so that the wire clamping plates can be fixed. The yarn penetrating through the yarn guide holes formed in the top faces of the yarn guide plates which are symmetrical up and down is automatically clamped under the elastic acting force, so that the problem that the yarn rebounds is solved, and the aramid yarn two-for-one twisting mechanism has the automatic yarn clamping function.
