Description

Technical Field

[0001] The invention relates to the technical field of aerated board production and processing, and in particular to a dry slotting system and a control method for processing autoclaved aerated concrete boards. Background Art

[0002] Autoclaved aerated concrete board (abbreviated as aerated board, AAC board) is a combined assembled building material. It 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, some boards used as walls or with other matching requirements need to be grooved; and most of the current grooved devices are as shown in the patent document with domestic authorization announcement number 106827256B and authorization announcement date 20191105: "A multi-axis grooved machine for aerated concrete blocks or boards " is similar to the structure disclosed in the invention, that is, a transmission member is used to move the formed whole cast embryo to the vertical groove cutter position for cutting; this cutting structure for the whole cast embryo obviously has great limitations in use. First of all, in terms of processing accuracy, the larger and more complex the tool structure is, the more difficult it is to ensure processing accuracy. Taking the above-mentioned patent document as an example, after the same batch of aerated panels are grooved by the device, the groove accuracy of the top aerated panel is bound to be smaller than that of the bottom aerated panel component, which makes it difficult to obtain finished products with consistent specifications for the same batch of aerated panels. For aerated panel components with different size requirements, the operator needs to repeatedly debug the position and structure of the groove cutter, which consumes a lot of energy and is not conducive to the work of front-line operators. This is the main problem currently faced. Summary of the invention

During this process, the negative pressure system connected to the negative pressure pipe (6) will continue to generate negative pressure to discharge the processing waste through the dust collection box; S4, when the second aerated board after the slotting process enters the conveying unit (1) corresponding to the stacking unit (4), a control operation opposite to step S2 is performed to complete the stacking process of one aerated board; thereafter, steps S2 to S4 are repeated to obtain a complete stacked aerated board structure after the slotting process.
