detailed description

Below in conjunction with accompanying drawing and embodiment the technical solution in the utility model is further described.

Example:

As shown in Figures 1 and 2, a wood cutting device with dust suction includes a housing 1, the housing 1 is a rectangular structure, the housing 1 is provided with a port 2, and the port 2 runs through the housing 1 horizontally Front and back, one end of the port 2 is for wood to enter, and the other end is for the cut wood to be sent out. The side wall of the housing 1 is fixed with a first motor 4 . Direction is perpendicular to the rotating shaft 13, and the cutting knife 14 corresponding to the port 2 is fixedly sleeved on the rotating shaft 13. When the first motor 4 starts, the output end of the first motor 4 rotates to drive the rotating shaft 13 to rotate, and the rotating shaft 13 When rotating, the cutting knife 14 is driven to rotate, and now the cutting knife 14 can produce a cutting effect on wood.

As shown in Figures 1 and 2, the interior of the housing 1 is provided with a transmission mechanism that transports the wood to the cutting knife 14 and cooperates with the cutting knife 14 to cut the wood, and the transmission mechanism is used for cutting the wood from the discharge The port 2 at one end sends out, and the shell 1 is provided with a dust-absorbing mechanism extending into the shell 1, and the dust-absorbing mechanism extends to the top and bottom of the conveying mechanism. Therefore, first put the wood from the port 2 used for feeding one end, cooperate with the transmission mechanism to transport the wood inward, and drive the cutting knife 14 on the rotating shaft 13 to cut the wood through the first motor 4, during the cutting process Sawdust and dust will be scattered. Due to the existence of the shell 1, the wood dust is blocked and limited to a large extent, and then the dust suction mechanism inside the shell 1 is used to suck the space above and below the transmission mechanism at the same time. Dust treatment, to collect wood dust to a greater extent, at this time, the wood dust is sucked away by the vacuum mechanism.

As shown in Figure 1, the transmission mechanism includes a second motor 12 and a shaft assembly, the second motor 12 is fixedly connected to the inner wall of the housing 1 and corresponds to the port 2, and the shaft assembly includes a drive shaft 5 parallel to the rotation shaft 13 and several driven shafts 6, the driving shaft 5 is fixedly connected to the output end of the second motor 12, and the several driven shafts 6 are all rotatably connected with the inner wall of the housing 1, specifically, the driven shafts 6 directly pass through the housing On the inner wall of the body 1 and the driven shaft 6 can rotate relative to the inner wall of the housing 1, several driven shafts 6 are distributed on the front and rear sides of the rotating shaft 13, and there is a drive shaft between the driving shaft 5 and several driven shafts 6. The shaft 5 rotates and at the same time drives several driven shafts 6 to rotate synchronously.

As shown in FIG. 1 , the driving shaft 5 is fixedly sheathed with an anti-skid soft cover 7 , and anti-skid particles are arranged on the anti-skid soft cover 7 . After the second motor 12 starts, the output end of the second motor 12 drives the driving shaft 5 to rotate, and because the driving shaft 5 is provided with a soft cover 7 for collision, the anti-skid particles arranged on the soft cover 7 for collision are arranged on the wood and the soft cover 7. When the drive shaft 5 abuts against the wood, the surface of the drive shaft 5 will generate greater friction with the wood to drive the wood to move to the inside of the housing 1. When the wood is driven to move to the inside of the housing 1, the wood is cut by the cutting knife 14 At this time, the friction force generated continuously by the driving shaft 5 will drive the wood to continue to move into the housing 1 for continuous cutting. The effect of internal movement.

As shown in Figures 1 and 2, the dust suction mechanism includes an exhaust fan 8 and a pipeline 9, the exhaust fan 8 is fixedly installed on the side wall of the housing 1, and the air outlet end of the exhaust fan 8 is conductively connected with a dust collection box 3, which is collected The dust box 3 is a rectangular box, and a filter material layer 10 is also provided in the dust collection box 3. The filter material layer 10 is a grid screen structure, and the filter material layer 10 is used to filter larger sawdust. For some processing plants , Larger sawdust can be recycled and reused with some technologies. The filter material layer 10 is installed inside the dust box 3 and can be disassembled. After the filter material layer 10 has filtered more wood chips, the filter material layer 10 is removed, and then the wood chips on the filter material layer 10 are taken out. A part of the pipeline 9 extends above the conveying mechanism, and another part of the pipeline 9 extends below the conveying mechanism. The pipeline 9 is provided with a plurality of suction holes 11 . The dust suction holes 11 are all arranged towards the conveying mechanism. Scattering of wood dust in the cutting process is multi-directional, dust suction holes 11 are set up and down towards the conveying mechanism, and wood dust can be collected better when dust suction holes 11 are sucked.

When the utility model is in use, first start the first motor 4, and the first motor 4 drives the rotating shaft 13 to rotate. When the rotating shaft 13 rotates, the cutting knife 14 rotates. At this time, the cutting work of wood can be carried out, and then the second motor is started. 12. After the second motor 12 is started, it drives the drive shaft 5 to rotate, and then puts the wood from the opening 2 for feeding. The wood collides with the drive shaft 5 and is sent into the housing 1 by the drive shaft 5 The inside conflicts with the cutting knife 14. At this time, the wood is in the state of being cut, and the exhaust fan 8 is started. Due to the existence of the shell 1, the wood dust dust is firstly blocked and limited to a large extent, and then it is matched with the inside of the shell 1. Dust suction process is carried out from the top and bottom of the driving shaft 5 and the driven shaft 6 at the same time, and the wood dust is collected to a greater extent. The wood dust generated when the wood is cut is sucked into the collection through the suction hole 11 Inside the dust box 3.
