[0021] To deepen the understanding of the present utility model, the present utility model will be further described in detail below in conjunction with embodiments. These embodiments are only used to explain the present utility model and do not constitute a limitation on the protection scope of the present utility model.

[0022] According to Figure 1 、 2 As shown in FIGS. 3, a structure of a woodworking band saw machine with splash prevention is proposed in this embodiment, which includes a workbench 1. Above the workbench 1, there is a sliding arm 4. At the lower end of the sliding arm 4, there is a sliding carriage 10. The sliding carriage 10 is slidably connected to the sliding arm 4. At the lower end of the sliding carriage 10, there is a swing arm cutting mechanism. When the swing arm cutting mechanism descends, the sliding carriage 10 slides along the sliding arm 4 to cut the wooden board placed on the workbench 1.

[0023] Inside the sliding carriage 10, there are multiple groups of track wheels. The track wheels are arranged on both sides of the sliding arm 4 and can slide along the track grooves opened on both sides of the sliding arm 4. The rotation of the track wheels is controlled by a motor outside the sliding carriage 10. The sliding carriage 10 is a commonly used sliding device in the prior art and will not be described in detail here.

[0024] At the upper end of the workbench 1, there is a support frame 2. The lower end of the support frame 2 is fixedly connected to the workbench 1. At the upper end of the support frame 2, there is a rotating seat 3. The rotating seat 3 is rotatably connected to the support frame 2. At the connection between the support frame 2 and the rotating seat 3, there is a rotation driving assembly;

[0025] At the upper end of the rotating seat 3, there is a fixedly connected mounting arm 5. One end of the mounting arm 5 is fixedly connected to the sliding arm 4. At the end of the mounting arm 5 far from the sliding arm 4, there is a counterweight device. The counterweight device is detachably connected to the mounting arm 5. The rotation driving assembly controls the rotation of the rotating seat 3. When the rotating seat 3 rotates, it drives the sliding arm 4 to swing through the mounting arm 5. Without adjusting the position of the wooden board, the cutting line of the swing arm cutting mechanism can be changed automatically, with high flexibility. At the end of the mounting arm 5 far from the sliding arm 4, there is a counterweight device. When the sliding arm 4 swings, the counterweight device keeps both ends of the mounting arm 5 balanced, improving the safety of the movement of the sliding arm 4.

[0026] Regarding the swing arm structure mechanism: The swing arm cutting mechanism includes a mounting plate 11, which is fixedly connected to the lower end of the sliding trolley 10. Below the mounting plate 11, there is an adjusting arm 12. The upper end of the adjusting arm 12 is rotatably connected to a first hinge seat 16 provided at the lower end of the mounting plate 11. The lower end of the adjusting arm 12 is provided with a cutting wheel 14. At the lower end of the mounting plate 11, there is a swing arm adjusting mechanism for controlling the retraction and lowering of the adjusting arm 12. A motor for controlling the rotation of the cutting wheel 14 is installed at the end of the adjusting arm 12. When cutting the wood placed on the upper end of the workbench 1, the swing arm adjusting mechanism will push the adjusting arm 12. The upper end of the adjusting arm 12 rotates around the first hinge seat 16, and the cutting wheel 14 at the end of the adjusting arm 12 drops and contacts the wood structure. When the sliding trolley 10 moves along the sliding arm 4, the cutting wheel 14 can cut the wood.

[0027] Specifically, an arc-shaped baffle 15 is sleeved on the upper half of the cutting wheel 14, and the arc-shaped baffle 15 is fixedly connected to the adjusting arm 12. The arc-shaped baffle 15 outside the cutting wheel 14 can block the wood chips generated during cutting, preventing the wood chips from splashing from both sides of the cutting wheel 14.

[0028] More specifically, the swing arm adjusting mechanism includes an electric push rod 13. The electric push rod 13 is placed between the mounting plate 11 and the adjusting arm 12. The mounting end of the electric push rod 13 is rotatably connected to a second hinge seat 17 provided at the lower end of the mounting plate 11, and the output end of the electric push rod 13 is rotatably connected to the outer side wall of the adjusting arm 12. When the electric push rod 13 pushes the adjusting arm 12, the cutting wheel 14 at the lower end of the adjusting arm 12 will drop, and the distance between the cutting wheel 14 and the workbench 1 will decrease. When the electric push rod 13 pulls the adjusting arm 12, the cutting wheel 14 at the lower end of the adjusting arm 12 will lift, and the distance between the cutting wheel 14 and the workbench 1 will increase.

[0029] The rotation of the rotating seat 3 is controlled by a rotation driving assembly. Specifically, the rotation driving assembly includes a first gear 7, a second gear 8, and a driving motor 9. The first gear 7 is sleeved on the outside of the rotating seat 3 and is fixedly connected to the rotating seat 3. The second gear 8 is placed on one side of the first gear 7 and meshes with the first gear 7. The mounting end of the driving motor 9 is fixedly connected to the outer side wall of the support frame 2, and the output end of the driving motor 9 is fixedly connected to the second gear 8. The rotation of the rotating seat 3 is controlled by the driving motor 9. When the driving motor 9 starts, it will drive the second gear 8 to rotate. The second gear 8 meshes with the first gear 7 during rotation, and then drives the rotating seat 3 to rotate.

[0030] The counterweight device is detachably connected to the mounting arm 5 to facilitate the replacement of the counterweight device by the staff. The counterweight device includes a counterweight block 6 and a threaded rod 18. The threaded rod 18 is fixedly connected to the end of the mounting arm 5 away from the sliding arm 4. The counterweight block 6 is sleeved outside the threaded rod 18, and the inner wall of the counterweight block 6 is threadedly connected to the outer wall of the threaded rod 18. When removing the counterweight block 6 from the mounting arm 5, the counterweight block 6 can be screwed out from the outside of the threaded rod 18.

[0031] Working principle: The swing arm cutting mechanism descends, and the sliding trolley 10 slides along the sliding arm 4 to cut the wooden board placed on the workbench 1. The rotation drive assembly controls the rotation of the rotating seat 3. During the rotation of the rotating seat 3, the sliding arm 4 is driven to swing through the mounting arm 5. Without adjusting the position of the wooden board, the cutting line of the swing arm cutting mechanism can be changed automatically, with high flexibility. A counterweight device is provided at the end of the mounting arm 5 away from the sliding arm 4. When the sliding arm 4 swings, the counterweight device keeps both ends of the mounting arm 5 balanced, improving the safety of the movement of the sliding arm 4.
