[0002] The needle punching machine is a blanket-making device that compacts and needles a certain thickness of refractory fiber blanket into a refractory fiber blanket. The needle with a triangular or other shaped cross section and a barbed hook on the edge is used to repeatedly puncture the fiber web.

[0003] After searching, the existing Chinese patent announcement number is: CN217922548U, which provides an emergency interception device for a dual-spindle rocker-arm needling machine. The patent is provided with an interception component on the support frame, and an elastic interception structure is formed between the interception plate in the interception component and the support spring to limit the movement of the fiber web after it is taken out of the needling machine. If there are needles left on the fiber web, the extrusion rotary block triggers the pressure sensor to stop the needling machine, which is convenient for taking out the needles left on the fiber web and preventing the needles from remaining on the fiber web after the staff takes out the fiber web. This is beneficial to the subsequent processing of the fiber web and reduces the occurrence of safety problems.
