Description

Technical Field

[0001] The utility model relates to the technical field of wood processing, in particular to a dust self-suction table saw. Background Art

[0002] A table saw, also known as a table saw or flat panel saw, is an electric sawing tool fixed on a workbench. It is widely used in straight cutting, bevel cutting and specific angle processing of wood, artificial boards and other similar materials. Due to its fixed design, compared with a handheld electric saw, the table saw provides powerful cutting capabilities while ensuring higher stability and cutting accuracy.

[0003] The existing table saw design lacks an automatically rising and falling dust suction device, which means that when processing materials of different thicknesses, it is impossible to achieve adaptive adjustment of the dust suction effect. This not only requires the operator to make frequent manual adjustments, affecting work efficiency, but may also lead to unstable dust suction efficiency. The increase in dust left in the cutting area not only worsens the working environment, but also poses a potential threat to the health of the operator. Secondly, the existing auxiliary positioning system is not user-friendly, inconvenient to use, and has poor positioning accuracy, which directly affects the accuracy and efficiency of cutting. The operator needs to spend more time and energy on manual calibration, which not only increases the workload, but also may lead to material waste and a decline in the quality of the finished product, further affecting the overall progress of the project and the final quality of the finished product.

[0004] Therefore, the lack of an automatic lifting dust suction device has resulted in the dust suction efficiency being affected by the material thickness and requiring manual adjustment, which not only reduces the operating efficiency but also affects the environment and the health of the operator. In addition, the auxiliary positioning system has design defects, is inconvenient to use, has low precision, increases the burden of manual calibration, causes material waste, and reduces the quality of finished products, thereby delaying the project progress and reducing the quality of finished products.
