Flexible cutting machine for sandwich plates

Abstract

The invention relates to a flexible cutting machine for sandwich plates. The flexible cutting machine for the sandwich plates can be arranged at the tail end of a composite sandwich plate production line and is used for cutting the continuously produced composite sandwich plates according to different set lengths. Two cutting devices are respectively arranged according to the composite sandwich plates with different core material types. One of the two cutting devices is a punching cutter device which can be used for cutting the composite sandwich plates with no steel strip and with EPS (expandable polystyrene) core materials. The other of the two cutting devices is a disc saw device which can be used for cutting any composite sandwich plates and is provided with a dust collecting system, the size of saw blades is unified, the disc saw device is automatically adjusted in a retractable manner according to the composite sandwich plates different in thickness, and disc saws are automatically retracted to return to original points after cutting is completed. Therefore, the service life of cutters is prolonged, pollution of core material dust produced during cutting to the working environment is reduced, and stagger distance of the upper disc saw and the lower disc saw can be adjusted manually according to requirements on stagger needed by composite sandwich plate connectors.

Description

technical field [0001] The invention relates to equipment in the field of composite sandwich panel production, in particular to a cutting machine for cutting composite sandwich panels with different core materials. Background technique [0002] As a new type of building board, composite sandwich panels have been more commonly used in more and more occasions. Composite sandwich panel production line is currently the main equipment for producing composite sandwich panels in China. It is a production equipment with a relatively high degree of automation composed of conveying section, composite section, cutting section, receiving section and other units. The cutting unit is located at the end of the sandwich composite production line. Its main function is to set different lengths of the continuously produced plates according to product requirements and cut them into products. The cutting quality of the cutting machine determines the quality of the final sandwich panel, and its ...

AI Technical Summary

Problems solved by technology

[0003] 1. The existing cutting units basically use a single disc saw device, and its defect is that saw blades of different sizes need to be replaced when cutting plates of different thicknesses; 2. The disc saw of the existing cutting unit has no telescopic function, and its defect is that : After cutting in place, the disc saw will quickly return to the original path, and will rub against the sandwich panel twice during the return process, thereby greatly reducing the service life of the disc saw blade; 3. The existing cutting unit still has No dust collection device is included, and its defect is that: the disc saw will generate a large amount of sawdust flying when cutting, which will seriously pollute the production environment; 4. The cutting platform of the existing cutting unit uses a square tube, and the plate to be processed is from Sliding on the square tube, when producing relatively thick composite sandwich panels, the square tube will produce relatively large friction with the composite sandwich panel.
