Background

The driving mechanism of the movable needle beam of the single-shaft driven needling machine is composed of a main shaft provided with a balancing weight block, an eccentric wheel, a connecting rod, a push rod, the movable needle beam and a needle plate. When the main shaft rotates, the connecting rod connected with the eccentric wheel is driven to move up and down, and then the push rod is driven to move up and down, so that the movable needle beam is driven by the push rod to carry out needling on non-woven fabrics passing below the needle plate by spines on the movable needle beam in the process of moving up and down, and the main shaft is unbalanced due to inertia when the movable needle beam rotates at a high speed due to the existence of the eccentric wheel.
