Description

Aerated concrete blank cutting device and application method thereof Technical Field The invention relates to the technical field of concrete processing, in particular to an aerated concrete blank cutting device and a using method thereof. Background The aerated concrete is a lightweight porous silicate product prepared by taking siliceous materials (sand, fly ash, siliceous tailings and the like) and calcareous materials (lime, cement) as main raw materials, adding a gas generating agent (aluminum powder), and carrying out the technological processes of proportioning, stirring, pouring, pre-curing, cutting, autoclaving, curing and the like. The method is characterized in that the aerated concrete blank is moved to a cutting procedure through a loading trolley after the pre-curing procedure is finished, and the side surface and top skin are cut and removed through a cutting device, and the layered action of horizontal cutting is carried out; In order to prevent the blank from adhering due to an up-down cutting gap in a subsequent autoclaved process, some prior technical schemes coat wax liquid on a cutting line, and the cutting line is required to be in a moving cutting state because the cutting is continuously carried out, for example, a cutting device for aerated concrete block blanks is disclosed in China patent application No. CN202122063479.1, a servo motor drives a cutting steel wire to carry out anticlockwise uniform reciprocating motion, and wax and concrete fragments are cleaned through a cleaning component; However, in actual production, because the cutting line is in a moving cutting state and the blank includes some hard components, the cutting line is often broken due to wear and uneven stress, and the trimming device for aerated concrete blank according to the chinese patent application No. CN202210925479.4 is arranged at the front end (the opposite rear end of the cutting device) of the moving direction of the loading trolley, when a certain cutting line breaks, the control system controls the trimming device to move to the same height, so that automatic cutting operation can still be performed without stopping the machine, although the automatic trimming can be completed through the trimming device after the cutting line breaks, the broken cutting line still exists in the blank, when the loading trolley continues to move, the cutting line left broken in the blank can lead to uneven cutting surface, and therefore, some processing modes still include cutting equipment and the loading trolley stop, the broken cutting line is manually pulled out first and then trimmed, the mode wastes a large amount of time and reduces the overall efficiency, and the automatic cutting operation under the state without stopping is seriously affected. Disclosure of Invention The invention aims to provide an aerated concrete blank cutting device which is simple and compact in structure, and can clamp and roll broken cutting lines so that the broken cutting lines can be gradually pulled away from blanks, the blanks are prevented from being damaged due to the fact that a loading trolley and a cutting mechanism relatively move and the cutting lines pull the blanks, and the overall cutting efficiency is improved.
