[0021] like Figure 1 As shown, a fiberboard edge grinding machine comprises a frame 1, a conveying mechanism 2 is installed on the top of the frame 1, and a limit assembly 3 and an edge grinding assembly are arranged in sequence from front to back along the conveying direction on both sides of the conveying mechanism 2, and the edge grinding assembly comprises a coarse grinding wheel 4, a fine grinding wheel 5 and a driving mechanism 6 for driving the coarse grinding wheel 4 and the fine grinding wheel 5 to roll synchronously, and the fine grinding wheel 5 is located behind the coarse grinding wheel 4 in the fiberboard conveying direction, and a first L-shaped mounting frame 7 is fixedly connected to the side of the frame 1, and a slide groove 8 is provided on the top surface of the first L-shaped mounting frame 7, and a slide plate 9 for cooperating sliding is provided in the slide groove 8, and first Z-shaped fixing frames are provided on both sides of the top of the slide plate 9 10, the coarse grinding wheel 4 and the fine grinding wheel 5 are rotatably mounted on each first Z-shaped fixed frame 10, and an adjusting mechanism 11 for adjusting the position of the slide plate 9 is provided on the first L-shaped mounting frame 7 to synchronously adjust the positions of the coarse grinding wheel 4 and the fine grinding wheel 5; pressure rollers 12 are provided on both sides of the edge grinding assembly above the conveying mechanism 2, and pressure roller mounting frames 14 are provided on both sides of the first L-shaped mounting frame 7, both ends of the pressure roller 12 are rotatably connected to the slider 13, the slider 13 is slidably connected to the pressure roller mounting frame 14, and the upper end of the slider 13 is movably connected to the pressure roller mounting frame 14 through an elastic component 15, so that the pressure roller 12 can press fiberboards of different thicknesses.

[0022] like Figure 2 As shown, in order to adapt to the limitation of a plate of a certain width, the limiting assembly 3 in the present application includes a second L-shaped mounting frame 31, a second Z-shaped fixing frame 32 and a limiting wheel 33. The second L-shaped mounting frame 31 is fixed to the side of the frame 1. The top surface of the second L-shaped mounting frame 31 is provided with a strip hole 311 arranged perpendicular to the conveying direction. The second Z-shaped fixing frame 32 is fixed to the strip hole 311 by bolts. The limiting wheel 33 is rotatably mounted on the second Z-shaped fixing frame 32. The rotation direction of the limiting wheel 33 is consistent with the conveying direction. The limiting wheel 33 is used for limiting without affecting the conveying of the fiberboard. When the limiting wheel 33 is installed, the fixing position of the bolt is adjusted in the strip hole 311, so that the position of the limiting wheel 33 can be adjusted to adapt to the limitation of a plate of a certain width.

[0023] like Figure 3As shown, the driving mechanism 6 includes a driving wheel 61, a driven wheel and a motor 64. The driving wheel 61 and the driven wheel 62 are respectively fixed to the upper ends of the rotating shafts of the coarse grinding wheel 4 and the fine grinding wheel 5, and the driving wheel 61 and the driven wheel 62 are connected by a belt 63.

When fiberboards of different thicknesses pass through, the movable rod 151 can drive the slider 13 to move up and down by utilizing the telescopic characteristics of the spring 152, so that the pressure roller 12 can press the fiberboards of different thicknesses, thereby improving the edge grinding accuracy.

[0027] When in use, a worker places the plate on the conveying mechanism 2. When conveying through the conveying mechanism 2, it is first limited by the limiting assembly 3, and then passes through the coarse grinding wheel 4 and the fine grinding wheel 5 in turn. The movement of the coarse grinding wheel 4 and the fine grinding wheel 5 is started by the motor 64, and the belt 63 is used to drive the driving wheel 61 and the driven wheel 62 to move synchronously, thereby driving the coarse and fine grinding wheels to rotate synchronously, so that the plate is rough-edged and then fine-edged, making the edge grinding more uniform. The limiting wheel 33 of the new type can adjust the position and can be adapted to the limiting of plates of different widths. The limiting process does not affect the conveying of the plate. The adjustment mechanism 11 can synchronously adjust the position of the coarse grinding wheel 4 and the fine grinding wheel 5, which is convenient for adjustment and improves the adjustment and grinding efficiency. It is also convenient for fine-tuning through manual adjustment, which is convenient for plates of different widths.

[0028] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
