Let-off device of warp knitting machine

According to the technical scheme, the warp let-off device is characterized in that the warp let-off device comprises a bottom plate, two supporting plates are fixedly connected to the top face of the bottom plate, and two fixing plates are fixedly connected to the top face of the bottom plate; the four rollers are all arranged on the top surface of the bottom plate; the supporting block is arranged on the left side of the bottom plate; the speed reducer is fixedly connected to the top surface of the supporting block; a driving motor is fixedly connected to one side of the speed reducer, an electronic let-off mechanism is fixedly connected to the top face of the speed reducer, and the rollers are arranged, so that when a hard wire material enters from the roller E, winds the roller E to enter the roller F, then winds the roller G and finally winds out from the roller H to be woven; therefore, the roller E, the roller F, the roller G and the roller H can provide large tension, the let-off requirement of hard w
