In order to ensure that the former welding wire can be effectively pressed when the subsequent welding wire falls down and the wire can be smoothly paid off when the welding wire is used, the rotation centers of the flywheel and the take-up paper tube are different. However, the distance between the wire feeding pipe outlet fixed on the inner circle of the flywheel and the inner wall of the wire collecting paper tube is changed constantly during working, and the time and the reaction force of the welding wire coming out of the wire feeding pipe and contacting the inner wall of the wire collecting paper tube are changed constantly under the action of centrifugal force. When the HST560 welding wire barreling machine works at a low speed, the rotating speed of the flywheel is low, and the action of the reaction force is not enough to influence the falling shape of the welding wire. If the take-up speed is increased, the rotating speed of the flywheel is correspondingly increased, and the welding wires cannot be regularly arranged when naturally falling due to the violently changed reaction force, so that the wire disorder machine is very easy to cause. This problem severely limits the production efficiency of HST560 wire barrel machines, resulting in a maximum take-up speed of about 12 m/s. With the continuous rising of production cost and labor cost, manufacturers urgently need to solve the problem that the production efficiency of the HST560 welding wire barreling machine is limited.
