A wire feeding device for a spring machine head

technical field

The invention relates to a wire feeding device for a spring head, belonging to the technical field of spring machinery.

Background technique

Pocketed springs are widely used in the production of mattresses and sofas. The pocketed springs have multiple springs, which are filled into the non-woven fabric layer after being pressed separately, and then sealed in the non-woven fabric layer by a welding sealing mechanism. One or more rows of continuous pocket springs are formed in the independent pocket chambers. In a mattress, thicker springs are set at the edge of the bed, while thinner springs are set at other positions of the mattress, so a coil spring equipment is often required to produce two types of pocket springs with different thicknesses. The prior art "Application No.: 2019203030083" discloses a multi-wire spring handpiece, wherein the wire feeding mechanism includes a drive wheel fixedly installed on a frame, and is characterized in that: the frame is installed with more than one The pressure rollers driven by the lifting mechanism, each of the pressure rollers corresponds to a steel wire, all the steel wires are guided by the guide wheel mechanism, and any of the pressure rollers cooperates with the drive wheel to press the corresponding steel wire. Conveying; the outer edge of the drive wheel is provided with two wire grooves for placing the steel wire.

In the above technology, when transferring steel wires, two steel wires with different thicknesses are transferred with different wire grooves. When the corresponding pressure roller rises, the thick steel wire moves but the thin steel wire does not move; and vice versa, when the thin steel wire moves, the thick steel wire does not move. Therefore, in fact, the above technology can only transmit one type of steel wire continuously, or two types of steel wire intermittently; and the two sets of pressure rollers need to repeat the lifting action for a long time, and the hinge point of the connecting rod is prone to loosening or Wear and tear will inevitably cause shaking during the lifting and lowering of the pressure roller, thus affecting the stability of the wire feeding.
