Yarn feeding and weft laying device for stitch-bonded fabric preparation

The invention discloses a yarn feeding and weft laying device for stitch-bonded fabric preparation. The yarn feeding and weft laying device comprises a fixed plate. A plurality of connecting plates are symmetrically mounted at the lower end of the fixed plate; two guide rails are jointly and symmetrically installed at the lower ends of a plurality of connecting plates, a plurality of guide rods are fixedly installed at the lower end of each guide rail, an air cylinder is installed on a plurality of guide rods in a sliding mode, a weft laying mechanism is fixedly installed at the lower end of the air cylinder, and a yarn feeding mechanism is fixedly installed at the upper end of the air cylinder. The air cylinder drives the yarn feeding mechanism and the weft laying mechanism to move synchronously, the accuracy of the device can be increased and yarn abrasion can be avoided. With application of multiple yarn guide shafts and yarn guide wheels, multi-layer weft laying can be conducted simultaneously during weft
