Reciprocating type full-automatic sanding production line for LNG ship insulation box foaming plate [ Field of technology ] The utility model relates to the technical field of surface sanding of an LNG ship insulation box foaming plate, in particular to a reciprocating type full-automatic sanding production line for the LNG ship insulation box foaming plate. [ Background Art ] The sanding and polishing of the foaming plate on the prior market are all manual or semi-automatic operation, the foaming plate is fixed by adopting a handheld or auxiliary clamp, and the surface to be sanded and polished is sent to the surface of a grinding wheel/cloth wheel, so that the sanding/polishing processing of the surface of the foaming plate is realized. By adopting the processing method, uneven supporting surface can be generated, the foaming plate is stressed unevenly to generate local deformation in the processing process, the condition of poor processing precision is caused, and each foaming plate needs to be positioned and supported and then processed, so that the processing efficiency is lower. At present, an automatic sanding production line also appears on the market, but the sanding production line on the market mostly adopts a continuous through design, and a workpiece is processed on one side by a sanding mechanism in one direction. For workpieces requiring double-sided sanding, manual overturning is generally required, so that the production efficiency is low, the positioning accuracy is poor, and particularly for easily deformed workpieces (such as thin plates). In addition, the foam board is conveyed by a conveyor belt in general, the supporting effect is unstable, and the placing position of the foam board cannot be kept consistent. When sanding, the end overgrinding phenomenon (commonly called as head biting and tail biting) of the feeding/discharging end of the foaming plate is caused by uneven bending of the two ends of the foaming plate and larger surface error value, so that the processing quality is affected.
