When the aerated concrete forming device is used specifically, aerated concrete is poured into the forming groove 1 from the pouring hole 23 and then is statically stopped to wait for the forming of the aerated concrete, and because the gas former is added into the aerated concrete, in the static stop process, the gas former generates gas to generate a large amount of bubbles in the aerated concrete, so that the volume of the aerated concrete expands, the cover plate 22 is pushed upwards, the cover plate 22 moves upwards to enable the left connecting rod 19, the right connecting rod 20 and the middle connecting rod 21 to rotate around the left hinge lug, the right hinge lug and the middle hinge lug respectively, the left pressing plate 24, the right pressing plate 27 and the middle pressing plate 29 are pressed to overcome the elastic force of the reset pressure spring 26 to move downwards, the left pressing plate 24, the right pressing plate 27 and the middle pressing plate 29 respectively drive the left pressing rod 25, the right pressing rod 28 and the middle pressing rod 30 to move downwards, and the driving wedge block 38 drives the left cutting knife 39, the right pressing rod 41 and the left cutting knife 39, The right cutter 41 and the middle cutter 43 cut off the plastic film 35 adhered to the conveyor belt, then the left pressure lever 25, the right pressure lever 28 and the middle pressure lever 30 continue to move downwards along with the continuous expansion of the aerated concrete, so that the driving wedge block 38 is aligned with the trapezoid groove 40, the left cutter 39, the right cutter 41 and the middle cutter 43 are reset under the action of the reset tension spring and do not contact with the left conveyor belt 2, the right conveyor belt 17 and the middle conveyor belt any more, after the aerated concrete is completely statically stopped, the buckle is opened, then the left conveyor belt 2, the right conveyor belt 17 and the lower conveyor belt 11 are started, the aerated concrete which is solidified and formed is driven to move through the rotation of the left conveyor belt 2, the right conveyor belt 17 and the middle conveyor belt, so that the discharging is realized, after the discharging is finished, the cover plate 22 does not bear the supporting force of the aerated concrete any more, and therefore the cover plate moves downwards under the action of self, The right pressure plate 27 and the middle pressure plate 29 apply pressure, and under the elastic force of the return pressure spring 26, the left pressure plate 24, the right pressure plate 27 and the middle pressure plate 29 respectively drive the left pressure rod 25, the right pressure rod 28 and the middle pressure rod 30 to slide upwards to return to the original position, and finally the driving wedge block 38 leaves the trapezoidal groove 40 and returns to the original position.

When the left conveyor belt 2, the right conveyor belt 17 and the lower conveyor belt 11 move, the reciprocating screw 5 is driven to rotate by the rotation of the rotating roller 32, and simultaneously, because the piston plate 6 is limited by the limiting bulges and the limiting sliding grooves and cannot rotate, under the rotation of the reciprocating screw 5, the piston plates 6 in the left cylinder 7 and the right cylinder 13 slide in a reciprocating manner along the axial direction, so that glue is continuously sucked into the left cylinder 7 and the right cylinder 13 through the first liquid inlet pipe 8 and the second liquid inlet pipe 15, and then the glue is sent into the left gluing box 3, the right gluing box 18 and the lower gluing box 12 through the first liquid inlet pipe 8 and the second liquid inlet pipe 15, so that the left gluing box 3, the right gluing box 18 and the lower gluing box 12 coat the glue on the plastic film 35 through the gluing port 4, the plastic film 35 is continuously pulled along with the movement of the left conveyor belt 2, the right conveyor belt 17 and the lower conveyor belt 11, the plastic film 35 passes through the gluing port 4 while moving, glue is applied, and the side of the plastic film 35 coated with glue is adhered to the surface of the conveyor belt when the plastic film passes through the gaps among the left film coating roller 36, the right film coating roller 37 and the lower film coating roller 34 and the conveyor belt, and moves to the side facing the inside of the forming groove 1 along with the conveyor belt, so that concrete is prevented from directly contacting the conveyor belt and adhering to the conveyor belt. Since the aerated concrete has a higher viscosity than the glue (a glue with a lower viscosity is used), the cut plastic film 35 leaves the forming trough 1 together with the aerated concrete.

The foregoing is merely an example of the present invention and common general knowledge of known specific structures and features of the embodiments is not described herein in any greater detail. It should be noted that, for those skilled in the art, without departing from the structure of the present invention, several changes and modifications can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicability of the patent.
