Detailed Description

In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1 to 5, an embodiment of the present invention provides a wood cutting machine, which includes a frame 1, wherein a first rotating shaft 2 is rotatably disposed on the frame 1, two cutting blades 3 arranged at an interval are fixed on the first rotating shaft 2, a fixed shaft 4 is fixed on the frame 1, a drum 5 is rotatably disposed on the fixed shaft 4, a cam 6 is fixed on the fixed shaft 4, the cam 6 is located in the drum 5, the drum 5 is provided with a wood transportation mechanism, the wood transportation mechanism includes a toothed plate 7 fixedly extending along a radial direction on two outer sides of the drum 5, and a first mounting shaft 8 and a second mounting shaft 9 fixed in the drum 5, the first mounting shaft 8 and the second mounting shaft 9 are both parallel to the fixed shaft 4, a mounting frame 10 is rotatably mounted on the first mounting shaft 8, a roller 11 is rotatably disposed in the middle of the mounting frame 10, one end of the mounting frame 10 is connected to a first tension spring 12, the first tension spring 12 and the roller 11 are respectively located on two sides of a first installation shaft 8, one end of the first tension spring 12 is fixed on a second installation shaft 9, the first tension spring 12 pulls the installation frame 10 to enable the roller 11 to always abut against the outer side wall of the cam 6, the other end of the installation frame 10 is rotatably provided with an engagement rod 13, the outer end of the engagement rod 13 extends out of a strip-shaped groove 14 formed in the roller 5, a support rod 16 is arranged on the installation frame 10 in the vertical direction, the installation frame 10 and the support rod 16 are connected in a T-shaped mode, a second tension spring 17 is arranged between the support rod 16 and the engagement rod 13, a baffle 18 is arranged at the rotary connection position of the engagement rod 13 and the installation frame 10, the baffle 18 abuts against the installation frame 10 to limit the angle of the second tension spring 17 for pulling the engagement rod 13, and the first rotating shaft 2 is driven to rotate by a first motor (not shown in the figure), a belt pulley 19 is fixed on the outer side wall of the roller 5, the belt pulley 19 is coaxially arranged with the fixed shaft 4, and a second motor (not shown) is driven on the belt pulley 19 through a belt. As shown in FIG. 1, the first shaft rotates clockwise, and the second motor drives the drum to rotate counterclockwise.

The timber conveying mechanism is provided with 2 groups, and is rotationally symmetrical by taking the straight line where the fixed shaft 4 is positioned as a central line.

And 2 toothed plates 7 on each wood conveying mechanism are arranged, and the toothed plates 7 are involuted with the meshing rods 13 to be used for meshing the wood 20.

The first rotating shaft 2 and the fixed shaft 44 are arranged on the same horizontal plane.

When in work, the wood conveying mechanism conveys the wood 20 to the toothed plate 7 of the roller, the rotation of the roller drives the wood 20 to rotate together, the convex part 61 of the cam 6 is positioned above the fixed shaft, as shown in the schematic diagrams of fig. 6 to 8, when the roller 11 abuts against the cam 6 and passes the convex portion 61 of the cam 6, the convex part 61 will push out the mounting frame 10 to the right side through the roller 11, so that the distance between the meshing rod 13 and the toothed plate 7 is close, at this time, the first tension spring 12 is stretched, and the tension is always kept, so that the roller 11 is abutted against the cam 6, the second tension spring 17 is kept still, the baffle plate 18 on the meshing rod 13 is always abutted against the mounting frame 10, when the wood 20 is bigger, the meshing distance between the meshing rod 13 and the toothed plate 7 is increased, the second tension spring 17 is lengthened, and the tension is always kept, so that the meshing rod 13 and the toothed plate 7 fix the bigger wood. The pulley 19 drives the roller 11 to roll continuously, so that the wood 20 is sent to the cutting blade 3 to be cut. In operation, the meshing rod 13 is located between the two cutting blades 3, the toothed plate 7 is located at the outer sides of the two cutting blades 3, and the cutting section length of the cut wood can be realized by adjusting the distance between the two cutting blades.
