When the wood chips flow, the fan blades are driven to rotate, and the rotation of the fan blades drives the rotation of the rotating shaft. When the rotating shaft rotates, the third threaded rod is driven to rotate through the pulley group. The rotation of the third threaded rod drives the piston rod to reciprocate, and the water inside the water tank is drawn into the second water pipe through the first water pipe, and is sprayed from the atomizing nozzle to the movable seat to reduce dust;

[0021] S5: Finally, the wood is cut by the high-speed rotation of the planer.

The rotation of the first rotating block drives the connecting plate to move inside the moving seat. The movement of the connecting plate drives the movement of the fixed plate, so that the fixed plate moves away from one side of the moving seat and approaches the workpiece. The two fixed plates clamp both sides of the workpiece to fix it, and the negative pressure fan is started. The wood chips generated in the cutting process are sucked into the moving seat through the dust collecting pipe connected by the third connecting pipe, the second connecting pipe and the first connecting pipe, thereby improving the working environment and the cutting stability.

[0024] 2. The present invention arranges a moving component. When the table rotary planer is working, the workpiece is first placed on the top of the workbench, and then the workpiece is fixed by two fixing plates. Then the second threaded rod is driven to rotate by a motor. The rotation of the second threaded rod drives the movement of the slider. The movement of the slider drives the movement of the moving seat. The movement of the moving seat drives the fixed plate to clamp the workpiece and move it to one side of the planer. Finally, the planer rotates at high speed to cut the wood.

[0025] 3. The present invention provides a dust reduction component. When the wood chips generated during the cutting process are sucked into the movable seat, the flow of the wood chips drives the fan blades to rotate. The rotation of the fan blades drives the rotation of the rotating shaft. When the rotating shaft rotates, the third threaded rod is driven to rotate through the pulley group.

[0037] When the desktop rotary planer is working, the workpiece is first placed on the top of the workbench 1, and then the first rotating block 7 is rotated. The rotation of the first rotating block 7 drives the connecting plate 5 to move inside the moving seat 3. The movement of the connecting plate 5 drives the movement of the fixed plate 4, so that the fixed plate 4 moves away from one side of the moving seat 3 and approaches the workpiece. The two fixed plates 4 clamp the two sides of the workpiece to fix it, and the negative pressure fan 15 is started. The wood chips generated during the cutting process are sucked into the moving seat 3 through the dust suction pipe 12 connected to the third connecting pipe 16, the second connecting pipe 14 and the first connecting pipe 13, thereby improving the working environment and the stability of cutting.

[0038] like Figure 1 to Figure 2 As shown, the moving assembly includes a slider 8 fixedly mounted at the bottom end of the moving seat 3, the inner wall of the slider 8 is threadedly connected with a second threaded rod 9, the second threaded rod 9 is rotatably mounted inside the workbench 1, and a motor 10 is provided at one end of the second threaded rod 9.

The rotation of the second threaded rod 9 drives the movement of the slider 8, and the movement of the slider 8 drives the movement of the moving seat 3. The movement of the moving seat 3 drives the fixing plate 4 to clamp the workpiece and move it to the side of the planer 2, and finally the planer 2 rotates at high speed to cut the wood.

[0040] like Figures 1 to 3 As shown, a recovery box 28 is slidably installed inside the movable seat 3.

[0041] The sucked-in wood chips are collected by the recovery box 28 for subsequent unified cleaning.

[0045] When the wood chips generated during the cutting process are sucked into the movable seat 3, the flow of the wood chips drives the fan blades 17 to rotate, and the rotation of the fan blades 17 drives the rotation of the rotating shaft 18. When the rotating shaft 18 rotates, it drives the third threaded rod 20 to rotate through the pulley set 19. The rotation of the third threaded rod 20 drives the piston rod 21 to move back and forth. The water inside the water tank 23 is drawn into the second water pipe 25 through the first water pipe 22 and is sprayed into the movable seat 3 from the atomizing nozzle 26. The water mist contacts the wood chips, thereby reducing the dust concentration in the air, which helps to improve the working environment.

[0046] like Figure 6 As shown, a one-way valve 24 is installed on the outer wall of the first water pipe 22 .

[0052] like Figures 1 to 3 As shown, the second connecting pipe 14 is configured as a bellows.

[0053] The first connecting tube 13 is connected to the third connecting tube 16 via the second connecting tube 14 so that the second connecting tube 14 is stretched when the dust suction seat 11 is adjusted in height, thereby ensuring a stable connection between the two.

[0054] A method for fixing a workpiece fixing device of a desktop rotary planer comprises the following steps:

[0055] S1: When the table rotary planer is working, the workpiece is first placed on the top of the workbench 1, and then the first rotating block 7 is rotated. The rotation of the first rotating block 7 drives the connecting plate 5 to move inside the moving seat 3. The movement of the connecting plate 5 drives the movement of the fixed plate 4, so that the fixed plate 4 moves away from one side of the moving seat 3 and approaches the workpiece, and the two fixed plates 4 clamp the two sides of the workpiece to fix it;

[0056] S2: After fixing, the second rotating block 31 is rotated to drive the fourth threaded rod 30 to rotate, and the rotation of the fourth threaded rod 30 drives the dust suction seat 11 to move, and the height of the dust suction seat 11 is adjusted so that the dust suction seat 11 is located above the workpiece;

[0058] S4: Start the negative pressure fan 15 at the same time, and suck the wood chips generated during the cutting process into the movable seat 3 through the dust suction pipe 12 connected to the third connecting pipe 16, the second connecting pipe 14 and the first connecting pipe 13. When the wood chips flow, the fan blades 17 are pushed to rotate. The rotation of the fan blades 17 drives the rotation of the rotating shaft 18. When the rotating shaft 18 rotates, it drives the third threaded rod 20 to rotate through the pulley group 19. The rotation of the third threaded rod 20 drives the piston rod 21 to reciprocate. The water in the water tank 23 is drawn into the second water pipe 25 through the first water pipe 22, and is sprayed from the atomizing nozzle 26 to the movable seat 3 to reduce dust;

[0059] S5: Finally, the wood is cut by the planer 2 rotating at high speed.
