Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0020] Please refer to Figures 1 to 3, in the embodiment of the present utility model, a double-headed saw with a guiding function includes a workbench 1. At both the left and right ends of the upper surface of the workbench 1, a support plate 2 is fixedly connected. At the top of the support plate 2, a mounting plate 3 is fixedly connected. A chute is provided on the upper surface of the mounting plate 3. At one end inside the chute, a first toothed plate 4 is slidably connected. At the other end inside the chute, a second toothed plate 5 is slidably connected. At the top of both the first toothed plate 4 and the second toothed plate 5, a hoop bottom plate 24 is fixedly connected. At the top of the hoop bottom plate 24, a concave clamping plate 6 is rotatably connected. On the outer surfaces of the front and rear sides of the concave clamping plate 6, an arc-shaped guiding groove 7 is provided. Inside the arc-shaped guiding groove 7, a guiding column block 9 is slidably connected. In the middle of the inner side of the concave clamping plate 6, a moving plate 8 is rotatably connected. The guiding column block 9 is fixedly connected to the moving plate 8. On one side of the guiding column block 9, a positioning clamp plate 10 is slidably connected. Outside the arc-shaped guiding groove 7, a plurality of positioning clamp holes 12 are provided. In the middle between the first toothed plate 4 and the second toothed plate 5, a second adjusting gear rod 23 is meshingly connected. At the left end above the support plate 2, a first motor 11 is provided. At the right end above the support plate 2, a second motor 19 is provided. Below the first motor 11 and the second motor 19, they are fixedly connected to the corresponding moving plate 8. The output end of the first motor 11 is fixedly connected to a first fixed connecting rod 13. The output end of the second motor 19 is fixedly connected to a second fixed connecting rod 20. One end of the first fixed connecting rod 13 is fixedly connected to a first saw head 14. One end of the second fixed connecting rod 20 is fixedly connected to a second saw head 18. On the upper surface of the first toothed plate 4, a drainage plate 17 is fixedly connected. The part where the positioning clamp plate 10 coincides with the guiding column block 9 is a cross column rod.
[0021] In this embodiment: When in use and it is necessary to adjust the distance between the first saw blade 14 and the second saw blade 18, rotate the second adjusting gear rod 23, driving the first toothed plate 4 and the second toothed plate 5 respectively meshed and connected to the upper and lower ends of the second adjusting gear rod 23 to slide synchronously towards the outside of the upper surface of the workbench 1, thereby driving the hoop bottom plate 24 correspondingly connected above the first toothed plate 4 and the second toothed plate 5 to slide along the chute towards the outside of the upper surface of the mounting plate 3. Thus, through the hoop bottom plate 24 connected above the toothed plate and the concave clamping plate 6 rotatably connected to the top of the hoop bottom plate 24, drive the first saw blade 14 or the second saw blade 18 correspondingly connected above the concave clamping plate 6 to slide towards the outside of the upper surface of the mounting plate 3, so that the distance between the first saw blade 14 and the second saw blade 18 is enlarged. Rotate the second adjusting gear rod 23 in the reverse direction to drive the meshed and connected first toothed plate 4 and second toothed plate 5 to slide synchronously towards the middle of the upper surface of the workbench 1, thereby driving the first saw blade 14 and the second saw blade 18 provided above to slide synchronously towards the middle of the upper surface of the workbench 1, so that the distance between the first saw blade 14 and the second saw blade 18 is reduced. When longitudinally adjusting the angle of the saw blade, pull out the positioning clamp plate 10 outward so that one end of the positioning clamp plate 10 is separated from the positioning clamp hole 12, and then rotate the moving plate 8. Under the restriction of the axis point where one end of the moving plate 8 is connected to the concave clamping plate 6, the guiding column block 9 fixedly connected to one side rotates by a specified angle around the arc-shaped guiding groove 7. Then push the positioning clamp plate 10 so that the column block fixedly connected to one end of the positioning clamp plate 10 is stuck into the positioning clamp hole 12, thereby fixing the position of the guiding column block 9 after sliding adjustment. The rotating moving plate 8 will drive the correspondingly connected saw blade to rotate by a specified angle through the motor installed above, completing the angle adjustment in sequence. When horizontally adjusting the angle of the saw blade, rotate the concave clamping plate 6 so that the concave clamping plate 6 rotates by a specified angle around the hoop bottom plate 24.
[0022] Please refer specifically to Figure 1 and Figure 4 In the middle of the front and rear sides of the workbench 1, a third toothed plate 16 is slidably connected. A feeding belt 15 is provided at the top of the third toothed plate 16. A plurality of pushing blocks 25 are fixedly connected to the outside of the feeding belt 15. In the middle of one end of the third toothed plate 16, a first adjusting gear rod 21 is meshed and connected. A third motor 22 is fixedly connected to the rear side of the first adjusting gear rod 21.
[0023] In this embodiment: When it is necessary to adjust the height of the feeding belt 15, the third motor 22 drives the first adjusting gear rod 21 fixedly connected to the output end to rotate, thereby driving the third tooth plate 16 meshed at one end to slide upward by a certain distance, so as to drive the feeding belt 15 connected above the third tooth plate 16 to move upward by a certain height. During feeding, the workpiece is placed in the space between the pushing blocks 25 fixedly connected to the feeding belt 15. The feeding belt pushes the workpiece steadily towards the first saw blade 14 and the second saw blade 18 through the pushing blocks 25. The first motor 11 and the second motor 19 are started. The first motor 11 drives the first saw blade 14 fixedly connected to one end of the first fixed connecting rod 13 to rotate through the first fixed connecting rod 13 fixedly connected to the output end. At the same time, the second motor 19 drives the second saw blade 18 fixedly connected to one end of the second fixed connecting rod 20 to rotate through the second fixed connecting rod 20 fixedly connected to the output end. When the workpiece contacts the first saw blade 14 and the second saw blade 18, the rotating first saw blade 14 and the second saw blade 18 cut the contacted workpiece. When the cut waste material falls onto the drainage plate 17 under the action of gravity, it slides along the inclination angle of the upper surface of the drainage plate 17 towards one end and separates from the device, falling into the collection box placed below.
[0024] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent replacements or changes, and should be covered by the protection scope of the present invention.
