DETAILED DESCRIPTION

(7) The present invention is further described with reference to and the attached drawings and specific embodiments. It should be noted herein that description of these embodiments is intended to help understanding of the present invention, instead of construing any limitation to the present invention. In addition, technical features involved in various embodiments of the present invention described hereinafter may be combined as long as these technical features are not in conflict.

(8) Referring to FIG. 1, FIG. 2, FIG. 3 and FIG. 4, a schematic view of a stage dedusting shield for a dust-free table saw, an exploded view of a dedusting shield, and a schematic structural view when the dedusting shield is raised, and a schematic view (1) of a working state of the dedusting shield are illustrated. The present invention provides a stage dedusting shield for a dust-free table saw, comprising: a shield assembly and a dust absorbing cover assembly; wherein the dust absorbing cover assembly is mounted between a follower board 11 and a rear portion of a saw blade 6 and is fixed by the follower board 11 mounted on a working stage 18. Since the saw blades 6 in the conventional table saws all rotate clockwise for cutting (from the tail of the motor), during workpiece cutting, wood chips and dusts generated at the front end of the saw blade (close to the saw teeth of the operator) are brought by the saw blade down to the underneath of the stage, and the wood chips generated at the rear portion of the saw blade (close to the saw teeth of the follower board) are generally aggregated at the workpiece and the stage. The dust suction cover 12 arranged at the relative position saves materials, and achieves dust-free wood cutting.

(9) The dust suction cover assembly comprises a dust suction cover 12, a dust suction soft pipe 16 and a rear rocker arm 7 sleeved onto the exterior of the dust suction cover 12.

(10) Further, a lower dust suction cover 15 is connected under the dust suction cover 12; wherein the lower dust suction cover 15 is connected to the dust suction cover 12 via a lower dust suction cover torsion spring 14 and a lower dust suction cover rotary pin 19. The lower dust suction cover 15 is horizontal at the bottom, and constantly maintains parallelly contact with the wood blocks 17 during workpiece feeding, thereby achieving a better protection effect.

(11) The rear rocker arm 7 is fixed to the follower board 11 via a rocker arm positioning screw 8, a positioning press spring 9 and a locking handle 10.

(12) The rear rocker arm 7 is connected to the shield assembly via a positioning steel wire 4, a rotary shaft and a screw, and the shield assembly comprises a front rocker arm 3, a right shield 1 and a left shield 5. The front rocker arm 3 rotates upwards for positioning relative to the rear rocker arm 7. In this way, during cutting, the saw blade 6 may be more visually observed, and the dust suction effect is not affected.

(13) The front rocker arm 3 is connected to the right shield 1 and the left shield 5 via a shield torsion spring 2. The right shield 1 and the left shield 3 connected via the shield torsion spring 2 may be automatically adjusted upwards during workpiece feeding, which satisfies the safety requirements during cutting. The dust suction cover 12 is connected to a front shield 22 via a dust suction cover rotary pin 20, a front shield torsion spring 23 and the dust suction cover torsion spring 13. The front shield 22 rotates along with the dust suction cover 12, such that the wood chips are effectively protected from flying towards the operator and the wood chips are suctioned by the suction pipe.

(14) The embodiments of the present invention are described in detail with reference to the accompanying drawings. However, the present invention is not limited to the embodiments described. For a person skilled in the art would derive various modifications, variations and replacements made to the embodiments without departing from the principle and spirit of the present invention shall all fall within the protection scope of the present invention.
