Technical Field

[0001] The utility model relates to the field of PS boards, in particular to a PS board drilling device. Background Art

[0002] PS board is a board made of polystyrene as the main raw material, also known as organic board, with the advantages of rigidity, insulation, good printability, etc. Its density is between 1.02 and 1.08, and it is a thermoplastic material. It has high transparency and is mainly used in packaging, container equipment, daily decoration, general electrical appliances, construction and other industries.

[0003] With respect to the above-mentioned related technologies, the inventors found that, according to the needs of different customers, some PS boards need to be drilled at their four corners after production. Due to the material characteristics of the PS board, it is easy to generate dust and debris when subjected to the mechanical force of drilling, and the conventional drilling device does not have a dust and waste collection mechanism, which causes the dust and debris generated by the PS board during drilling to easily splash to other parts of the board surface, thereby increasing the workload of subsequent board surface cleaning and lamination operations, and affecting the production efficiency of the PS board.
