Bag making machine for air bag of air column bag massage instrument

The bag making machine structurally comprises a conduction table, a hot pressing mechanism, an operation table and a base, the conduction table is installed at the upper end of the operation table, the bottom of the operation table is connected with the upper surface of the base, and the hot pressing mechanism is fixedly embedded in the upper end of the base; when the telescopic frame ascends and the contact plate is separated from the air bag raw materials, the lifting rod can push the contact plate to reset through thrust generated by the springback piece on the lifting rod, so that the contact plate can vibrate a molten plastic layer of the air bag raw materials at the bottom of the contact plate to be loosened, and then the hot pressing plate is pushed through the plate face to be rapidly reset. The two hot pressing plates are extruded by the air bag raw materials again to slide outwards along the plate faces, so that the bearing plates can slide outwards under the action of inertia force, then the outer
