Hollow elevator guide rail soft foam strip filling device

The invention discloses a soft foam strip filling device for a hollow elevator guide rail. The soft foam strip filling device comprises a supply component, a foam strip assembly and a pushing assembly. The foam strip assembly is rotationally arranged in the supply part, and the pushing assembly is fixed to one side of the supply part and used for adjusting the position of a whole foam strip in the foam strip assembly; a cutting-off assembly, a clamping assembly for fixing a hollow elevator guide rail and a dragging assembly are sequentially arranged in the same vertical plane of the output end of the supply assembly in a gradient mode. And the dragging assembly is matched with the cut-off assembly to work, so that the soft foam strips output by the supply component are transferred into the hollow elevator guide rail and cut off, the hollow elevator guide rail can be used for filling the soft foam strips, the hollow elevator guide rail is obliquely installed at a certain inclination angle, the gravity generate
