Aerated concrete blank surface slitting device

Abstract

The invention discloses an aerated concrete blank surface slitting device which comprises a gantry machine frame, a machine frame beam, a dragging trolley and a guide rail. The gantry machine frame is divided into a horizontal slitting area at the front end, a perpendicular slitting area in the middle and a surface layer adsorption area at the rear end. A benchmark sampling gate is arranged coaxially in the front of the entering direction of the slitting device gantry machine frame. The benchmark sampling gate and the gantry machine frame are each provided with a scaleplate and a laser positioning instrument. According to the aerated concrete slitting technology and building material characteristics, on the basis of the ultrasonic distance measuring principle, the advanced three-dimensional numerical control technique is applied to the aerated concrete blank slitting technology, the blank surface dynamic benchmark sampling concept is put forward, and digital sampling is carried out on each mold-stripped aerated concrete blank body, so that the original operation mode of traditional manual estimation and manual measurement is fundamentally changed, the production effect is improved, the labor cost is saved, the product configurational dimension is more accurate, the blank effective utilization rate is greatly improved, benefits are obtained for enterprises, and energy conservation and emission reduction are achieved for the society.

[0003]In recent years, a large number of aerated concrete block production lines have been launched in various parts of our country, and the linear cable concrete block cutting machine is an important component of the aerated concrete block production line Part of it is applied to the matrix block cutting, and the production efficiency is high. However, looking at the existing production process, it will be found that the existing equipment has the functions of reference positioning on the surface of the block blank, wire rope control and cutting adjustment. Technical flaws of benchmark positioning:

[0004]Aerated concrete is made of siliceous materials (sand, fly ash and silicon-containing tailings, etc.) and calcareous materials (lime, cement) as the main raw materials. Adding gas-generating agent (aluminum powder), light porous silicate products made through batching, stirring, pouring, pre-curing, cutting, autoclaving, curing and other processes, because they contain a large amount of uniform and fine particles after gas-generating However, in the actual production process, due to variable factors such as gravity, mixing, stirring, aluminum powder chemical replacement reaction speed and the difference in components, each concrete blank is turned over 90 °After demoulding, the density of the molded body is uneven; the geometric shape is not fixed, just like the jelly and tofu that have just been demoulded, after being transported by the conveyor line, when entering the cutting device, its dynamic reference positioning There is an actual deviation between the size and the preset fixed wire rope position on the slitting device. Once the green body is insufficiently gassed, the cutting function of the three side skins will fail. At this time, it is necessary to stop the machine and readjust the wire rope position to produce. In order to avoid this kind of phenomenon, manufacturers often use more reserved skin trimming size, so that the effective utilization rate of the green body will be reduced
