[0060] Referring to Figures 1 to 9The dust collecting structure 1 of the band saw machine provided by the preferred embodiment of the present application is installed on a fixed table 2 of a band saw machine, surrounds a sawing band (not shown), and is biased by a worktable 3 of the band saw machine which is biased relative to the fixed table 2. The worktable 3 has an arc frame 31 for biasing.

[0061] The dust collecting structure 1 mainly comprises a fixed cover 40, a plurality of coupling members 60, a pivot member 70, a biasing cover 80, and a resilient member 90.

[0062] The fixed cover 40 has a first front plate 41, a first side plate 42, a first rear plate 43, two fixing portions 45, a first pivot portion 47, and a first stop member 50. The first front plate 41, the first side plate 42, and the first rear plate 43 are connected in sequence to surround the sawing band. The first side plate 42 has a first bevel edge 421 which is matched with the direction of the biasing of the worktable 3. The first rear plate 43 has a first escape opening 431 which corresponds to the arc frame 31 of the worktable 3. The two fixing portions 45 are respectively connected to the lower portions of the first front plate 41 and the first rear plate 43. Each of the fixing portions 45 is provided with a plurality of mounting holes 46, and the first pivot portion 47 is located on the upper edge of the first front plate 41. The first stop member 50 is installed on the first side plate 42, and the first stop member 50 has a first stop portion 51 which is located on the inner side of the first side plate 42.

[0063] Each of the coupling members 60 is used to fix the fixed cover 40 to the fixed table 2. In the present embodiment, the coupling members 60 are magnetic members, and each of the coupling members 60 is installed on each of the mounting holes 46 of the fixed cover 40. The fixed table 2 is made of a magnetic metal material.

[0064] The pivot member 70 is pivotally connected to the first pivot portion 47 of the fixed cover 40.

[0065] The biasing cover 80 has a second front plate 81, a second side plate 82, and a second pivot portion 85. The biasing cover 80 is pivotally connected to the fixed cover 40 by the pivot member 70, and can be biased relative to the fixed cover 40 by being pressed by the worktable 3. The second front plate 81 corresponds to the first front plate 41 of the fixed cover 40, and is pressed by the worktable 3. The second front plate 81 has a second escape opening 811 which corresponds to the arc frame 31 of the worktable 3. The second side plate 82 is connected to the second front plate 81, and abuts against the first side plate 42 of the fixed cover 40. The second side plate 82 has a second bevel edge 821 and a second stop portion 823. The second bevel edge 821 is close to the first bevel edge 421 of the fixed cover 40, and the second stop portion 823 blocks the first stop portion 51 of the first stop member 50 of the fixed cover 40. The second pivot portion 85 is located below the second front plate 81, and is pivotally connected to the pivot member 70.

[0066] The resilient member 90 is a torsion spring in the present embodiment, and is sleeved on the pivot member 70. The two ends of the resilient member 90 respectively abut against the first front plate 41 of the fixed cover 40 and the second front plate 81 of the biasing cover 80, and provide a restoring force for returning the biasing cover 80.

[0067] When the worktable 3 is not tilted, the deflection cover 80 is close to the worktable 3, the second front plate 81 and the upper edge of the second side plate 82 of the deflection cover 80 are close to or abut against the worktable 3, and sawdust is not easy to fall out between the deflection cover 80 and the worktable 3.

[0068] The actuation state of the embodiment is shown in Fig. 4. Figures 10 to 12 When the worktable 3 is tilted at an angle, the deflection cover 80 is pressed down by the worktable 3, the deflection cover 80 is deflected relative to the fixed cover 40 with the pivot 70 as the center, the second front plate 81 and the upper edge of the second side plate 82 of the deflection cover 80 still abut against the worktable 3, and sawdust is not easy to fall out between the deflection cover 80 and the worktable 3.

[0069] As described above, the dust collection structure 1 of the band saw machine provided by the preferred embodiment of the present application can prevent sawdust from leaking out when the worktable 3 is horizontal or deflected, and facilitates the suction and removal of the sawdust, thus achieving the purpose of the present application.

[0070] In addition, one of the fixed portions 45 of the fixed cover 40 is horizontal, and the other fixed portion 45 of the fixed cover 40 is vertical, which can further improve the stability of the fixation in multiple directions. Furthermore, the deflection cover 80 can avoid collision with the components of the band saw machine when deflected by the second bevel 821.
