Description

Sliding table saw vacuum device

technical field

The utility model relates to a kind of wood processing equipment, more specifically, it relates to a dust suction device for a sliding table saw.

Background technique

In the wood processing industry, the development of modern mechanized operations has not only improved work efficiency, but also brought a bad impact on the working environment of operators. When the ordinary sliding table saw is processing, due to its own processing characteristics, a large amount of wood dust will appear in the working area. The appearance of dust will not only cause dust pollution in the area, but also affect the health and work efficiency of workers to a large extent. Dust flying into the air will be inhaled by workers into the lungs, which will definitely damage the health of the operator's respiratory system in the long run. On the other hand, the flying dust will reduce the visibility of the air, which will cause the operator's poor vision during operation and cause accidents. Hidden danger. In order to solve the above problems, there is an existing dust suction device for sliding table saw, which can refer to the utility model patent application number 201220552308.3. The dust suction device for sliding table saw includes a support frame, a dust suction cover and a dust suction pipe. To support the dust suction pipe, the saw blade is connected to the rotation on the workbench. The dust suction hood is located directly above the saw blade. The emitted dust is sucked away to ensure the quality of the surrounding air. However, the wood to be processed is high or low, and the dust collection cover above the saw blade is fixed to the support frame, which is inconvenient to adjust up and down. If the distance between the dust collection cover and the saw blade is too far, the generated dust cannot be effectively removed. , If the dust cover is closer to the saw blade, the wood cannot pass through when processing taller wood.

Detailed ways

The embodiment of the dust suction device for the sliding table saw of the present invention will be further described with reference to the accompanying drawings.

A dust suction device for a sliding table saw, comprising a dust suction pipe 4, a dust suction cover 3 located above the saw blade 2, and a support frame 5 for supporting the dust suction cover 3 and the dust suction pipe 4, the saw blade 2 is rotatably connected to the working On the table 1, the dust suction pipe 4 communicates with the dust collection cover 3, and the distance between the dust collection cover 3 and the saw blade 2 can be adjusted by the adjustment mechanism 6. height, so that the dust collection hood 3 is closer to the cutting place, so that the generated dust can be better absorbed. When the height of the wood to be processed is large, the height of the dust collection hood 3 can be raised appropriately, so that the wood can be processed smoothly. Pass through, and the dust collection cover 3 is also close to the cutting place of timber, convenient suction dust.

The adjustment mechanism 6 includes a connecting piece 61, a drive screw 63 and a drive assembly 62 for driving the drive screw 63 to rotate.
