Batching: Mix the raw materials according to a certain formula. Usually, the raw materials are fully mixed in a mixer or mixing tank to ensure that the various raw materials are evenly distributed. Casting mold: Pour the mixed raw materials into the aerated concrete block mold. The mold can be a metal mold, a wooden mold or a plastic mold, and different mold shapes and sizes can be selected according to needs. Vibration compaction: Use vibration equipment to vibrate and compact the concrete in the mold to ensure that the concrete fully fills the mold and eliminates bubbles, thereby improving the density and strength of the block.

[0003] At present, the filled molds need to be placed in a curing room or open field for curing to allow the concrete to fully solidify and harden. The curing time usually ranges from several hours to several days to ensure that the blocks reach the designed strength. After the concrete is fully cured, the molds are removed, the formed aerated concrete blocks are taken out, and placed on the cutting trolley. After horizontal and vertical cutting, concrete blocks of different sizes are formed, and then the aerated concrete is placed on the turning machine.

[0004] In the prior art, it is necessary to support one side of the concrete block by a flip plate on a flipping machine, and then flip it 90 degrees so that the bottom skin on the concrete block faces the ground, and then scrape the bottom skin off with a scraper, and then flip the concrete block back to its original position. However, during the long cleaning process of the scraper, the working end of the scraper will adhere to concrete materials or impurities, and the materials or impurities will cause wear and corrosion to the scraper, affecting the cleaning effect of the scraper on the bottom skin of the concrete block.
