Description

Technical Field

[0001] The invention relates to the technical field of assembled building material preparation devices, and in particular to an autoclaved aerated concrete slab wet slotting system and a control method thereof. Background Art

[0002] Autoclaved aerated concrete board (abbreviated as aerated board, AAC board) as a combined assembled building material has been widely promoted and applied in China due to its economic, convenient construction and environmentally friendly production characteristics. The production of aerated board requires that the raw materials such as cement, lime, silica sand are fully mixed into slurry and then poured into a small car with a steel mesh for casting and molding. After being formed into a whole concrete structure in the casting car, it is cut into certain sizes. In addition, groove processing is required on some boards used as walls or with other matching requirements; the current groove technology can be roughly divided into two categories, one is dry groove, which mainly uses a groove cutter for active cutting processing on the hard molded board obtained after the concrete board is steamed and cooled; the other is wet groove, which is for the preliminary molded board obtained by pouring the concrete board. Since this type of molded board has not been steamed, its board structure is relatively soft. For it, a fixed groove cutter can be directly set during the transfer process of the board, and the groove cutter can be squeezed by the power of the board's own movement to complete the cutting. Since dry grooving easily generates a large amount of dust, wet grooving is mostly used for grooving on indoor production lines; and most of the current domestic wet grooving structures are similar to the disclosed structure in the patent document "A Autoclaved Aerated Concrete Building Material Grooving Device" with a publication number of 209832224U and a publication date of 20191224, that is, two sets of relative vertical groove knives are respectively arranged on the left and right sides of the forward direction of the plate to groove both sides of the plate; considering the difficulty of processing, the cutting of aerated concrete panels is generally carried out directly after casting, and the objects faced by this wet grooving are mostly stacked cut plates, but in the specific grooving process, the upper and lower plates can only be guaranteed to be stable by friction between the overall structure, and the same vertically arranged groove knives will make the groove precision of the upper plate smaller than that of the bottom, and under the influence of structural strength, the groove knives of this structure are not conducive to processing deeper grooves; this is the problem that needs to be solved at present.
