Description
Technical Field
The utility model relates to an electric cutting tool field, in particular to dustless bench saw with dust absorption mechanism.
Background
Table saws are widely used in the timber processing industry for cutting a variety of materials, for example: wood, medium density fiberboard, high density fiberboard or other materials and composite boards. Cutting of wood board materials using table saws typically produces a significant amount of dust of wood chips. In a typical workplace, the wood dust is usually scattered over a large area, and the fine dust particles are also released into the air, which not only pollutes the environment, but also the inhalant of the fine dust particles can injure the health of workers. When an operator is sawing wood, chips are produced which theoretically fall onto the table, but it is well known that the chips themselves are quite light in weight and therefore fly mostly; especially when wind exists in a working site, the sawdust flies upwards and around along with the wind, and if the operator inhales the sawdust for a long time and deposits in the lung, the sawdust is harmful to the health of the operator. Moreover, when the sawdust on the ground is cleaned after the work is finished, the sawdust can fly everywhere again, which is very troublesome.
In order to solve the problems, large enterprises have technical solutions by adding a dust collection system, but the large enterprises have complex structures and high production cost, and are impractical and difficult to popularize and use for small sawing machines which are widely applied to household operation. Some table saws are available with built-in suction cleaners, however, these table saws do not adequately clean and still leave a significant amount of wood dust.
