[0023] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0024] like Figure 1 As shown, a plywood surface burr polishing device according to this utility model includes a worktable 1, such as...Figure 4 As shown, a plywood 3 is placed on the top surface of the workbench 1. A second drive motor 13 is installed in the middle of the rear side of the workbench 1. The output end of the second drive motor 13 is equipped with a polishing roller 2 for polishing at the highest point. Both ends of the polishing roller 2 penetrate the workbench 1. The polishing roller 2, which is longer than the width of the plywood 3, ensures polishing efficiency. At the same time, the polishing roller 2, which polishes at the highest point, polishes the bottom surface of the plywood 3 located on the top surface of the workbench 1. This prevents the plywood 3 from being unable to be polished due to factors such as its thickness, thus ensuring the applicability of the device.

[0025] A drive motor 10 is installed on one side of the worktable 1. The output end of the drive motor 10 is connected to a lead screw 9 located inside the worktable 1. The line connecting the two ends of the lead screw 9 is perpendicular to the line connecting the two ends of the polishing roller 2. Figure 2 As shown, a movable block 8 is threaded onto the lead screw 9. A support plate is fixed to the end of the movable block 8 via a connecting rod. The connecting rod passes through the worktable 1 and is slidably connected to the worktable 1. A cylinder 7 with a vertical output direction is installed on the support plate. A pressure box 4 located above the worktable 1 is installed at the output end of the cylinder 7 via a connecting plate. The movable block 8 moves horizontally on the lead screw 9 via the operation of the drive motor 10. The movement of the movable block 8 drives the movement of the cylinder 7, which in turn drives the movement of the pressure box 4. At the same time, the operation of the cylinder 7 drives the pressure box 4 to rise and fall, thereby pressing plywood 3 of different thicknesses, increasing the applicability of the device.

[0026] A turntable 6 is rotatably mounted on one side of the pressure chamber 4, and a bidirectional threaded rod 11 located inside the pressure chamber 4 is fixed to the end of the turntable 6. Figure 3 As shown, threaded blocks 12 are symmetrically threaded on the bidirectional threaded rod 11. The threaded blocks 12 pass through the pressure box 4 and are slidably connected to the pressure box 4. Each end of the threaded block 12 is fixed with a limiting block 5 located at the bottom of the pressure box 4. The plywood 3 is located between the two limiting blocks 5, and the line connecting the two limiting blocks 5 is perpendicular to the line connecting the two ends of the polishing roller 2. By rotating the turntable 6, the bidirectional threaded rod 11 is rotated, thereby causing the two threaded blocks 12 to move synchronously in opposite directions on the bidirectional threaded rod 11. The movement of the threaded blocks 12 causes the limiting blocks 5 to move, thereby changing the distance between the two limiting blocks 5. This makes the device suitable for plywood 3 of different lengths, increasing the applicability of the device. At the same time, the two limiting blocks 5 restrict the position of the plywood 3 on the left and right sides, and the pressure box 4 lowers to restrict the position of the plywood 3 up and down. The drive motor 10 drives the pressure box 4 to move horizontally, thereby causing the limiting blocks 5 to move and move the plywood 3 to contact the highest point of the polishing roller 2. Then, the polishing roller 2 polishes the plywood 3. The device has a high degree of automation and saves time and effort.

[0027] like Figure 1As shown, the height of the limiting block 5 is less than the thickness of the plywood 3, ensuring that the limiting block 5 will not contact the top surface of the worktable 1 when the pressure box 4 presses down on the plywood 3, thereby reducing the contact area and thus reducing friction and reducing the kinetic energy consumption when the plywood 3 moves. The length of the pressure box 4 is equal to the length of the worktable 1, which avoids the situation where the length of the pressure box 4 is greater than that of the worktable 1, which would require more space and, even if the limiting block 5 can hold a longer plywood 3, would not be able to drive the plywood 3 to perform a full polishing operation. At the same time, it also avoids the situation where the length of the pressure box 4 is too small, resulting in a limited spacing between the limiting blocks 5 and thus a smaller applicable range of the device.

[0028] In use, the plywood 3 is placed on the top surface of the workbench 1 and between the two limiting blocks 5. The cylinder 7 drives the pressure box 4 to descend, thereby pressing down the plywood 3. The turntable 6 is rotated so that the two limiting blocks 5 clamp the plywood 3. The drive motor 10 drives the limiting blocks 5 to move horizontally, thereby moving the plywood 3 to the top of the polishing roller 2 for polishing.

[0029] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
