The short warp feeding method of the air welding net comprises the following steps: through the auxiliary device of the hollow type welding net, an operator is positioned on one side of the feeding rack and places short warps in grooves in the moving plate, the push plate is positioned at the rear part of the moving plate at the moment, the moving plate is pushed by the push rod to move to a corresponding position on the sliding frame, the short warps are aligned with the threading holes, in order to avoid the moving plate moving to the limiting device on the sliding frame to generate inertia and move the position of the short warps, a deceleration strip can be arranged on the sliding frame, and the vibration absorption elements are laid on the limiting device. Pulling the pull rope at the front end of the movable plate to drive the push plate to move forwards and push the short warp to be in place, thereby completing the warp threading work. And then, pulling the push rod to enable the moving plate to return, lifting the sliding frame through the lifting device at the moment to avoid collision between the long warp threads fed into the threading hole by the feeding mechanism and the sliding frame, pulling the pull rope at the rear end of the moving plate by an operator on the next step to drive the push plate to move backwards and be in place, then putting the short warp threads into the moving plate, and repeating the operation on the principle to enable the second batch of short warp threads to penetrate.

By adopting the method for feeding the hollow welding net short warp threads by the aid of the hollow welding net auxiliary device, operators can avoid the operation that each piece of net is required to climb the rack to penetrate the short warp threads, labor intensity is reduced, and production efficiency is improved.
