The window 5 is provided with an automatic grinding component, which includes a horizontal slide 6, a column 7, a crossbeam 8 and a grinding roller 9. Horizontal slides 6 are provided on both sides of the feeding window 5. The moving direction of the horizontal slide 6 is parallel to the feeding window 5. The top of the horizontal slide 6 is fixed with a column 7. The two ends of the crossbeam 8 are respectively slidably set on the two columns 7. The crossbeam 8 moves along the height direction of the column 7. The grinding roller 9 is rotatably installed under the crossbeam 8. The wooden boards to be polished are stacked in the hollow stacking box 2 and supported by the support plate 4. When polishing, the lifting plate 3 moves upward to lift the wooden boards in the hollow stacking box 2 upward, so that the top wooden board can be put into the The board is then moved into the loading window 5. When the height of the board to be polished is higher than the height of the top surface of the polishing table 1, the lifting plate 3 stops moving. At this time, the board is in a polishing state, and the board is partially located in the loading window 5. The horizontal movement of the board is limited by the loading window 5, so that the top surface of the board is completely exposed. Then, the crossbeam 8 drives the polishing roller 9 to move downward, so that the polishing roller 9 contacts the top surface of the board for polishing. The axial direction of the polishing roller 9 covers the board, and then the polishing roller 9 is driven to move by the horizontal slide 6, and its moving direction is perpendicular to the axis of the polishing roller 9, so that the top surface of the board is completely polished, and the bottom surface of the board is limited by other boards, thereby limiting the vertical movement of the board, which can avoid the board from being offset during the polishing process. The polishing surface of the wooden board is completely exposed, and the single-sided polishing of the wooden board can be completed in one polishing operation, which improves the polishing efficiency. A pushing mechanism is arranged on the polishing workbench 1, and the pushing mechanism includes a pushing cylinder 25 and a conveyor belt 26. The telescopic shaft of the pushing cylinder 25 is connected with a pushing plate 27. The conveyor belt 26 is located at one end of the polishing workbench 1, and the conveyor belt 26 is located on the moving path of the pushing plate 27. When the top surface of the wooden board is polished, the lifting plate 3 drives the next wooden board to rise to the polishing state. At this time, the polished wooden board is completely separated from the loading window 5, and the pushing cylinder 25 drives the pushing plate 27 to move horizontally, and pushes the polished wooden board into the conveyor belt 26. This cycle is repeated, and the wooden boards in the hollow stacking box 2 are polished in turn.

[0022] Embodiment 2

[0023] Based on the first embodiment, Figures 1 to 3 As shown, linear drive modules 19 are installed on both sides of the loading window 5, and two horizontal slides 6 are respectively installed on the slides of the two groups of linear drive modules 19. A vertical slide groove 20 is opened on the side wall of the column 7, and a screw rod 21 is rotatably arranged in the vertical slide groove 20. A screw slider 22 is threadedly mounted on the screw rod 21, and the screw slider 22 slides and fits in the vertical slide groove 20. The two ends of the beam 8 are respectively connected to the two screw sliders 22. The horizontal slide 6 is driven by the linear drive module 19 to make a linear movement on the horizontal plane, thereby driving the column 7 and the beam 8 to move, and then driving the grinding roller 9 to move horizontally to achieve comprehensive grinding of the top surface of the wooden board. A screw motor is installed on the top of the column 7, and the screw motor drives the screw rod 21 to rotate, so that the screw slider 22 moves linearly along the axial direction of the screw rod 21, so as to drive the beam 8 to move up and down, so that the grinding roller 9 contacts the wooden board to complete the grinding operation.

[0025] On the basis of the second embodiment, a pressure sensor is embedded at the bottom of the crossbeam 8, the pressure shaft of the pressure sensor is connected to the grinding shell 23, the grinding roller 9 is rotatably installed on the grinding shell 23, and the pressure sensor is used to determine whether the grinding roller 9 contacts the wooden board. The grinding pressure can also be controlled according to the pressure feedback of the pressure sensor. A motor is installed at one end of the grinding shell 23, and the output shaft of the motor is transmission-connected to one end of the grinding roller 9. The motor drives the grinding roller 9 to rotate at a high speed to complete the grinding operation of the wooden board.

[0026] Embodiment 4

[0027] Based on the third embodiment, Figure 1 As shown, the automatic loading assembly also includes a support platform 10 and a lifting cylinder 11. A through hole 12 is opened on the support platform 10, and the through hole 12 is located directly below the loading window 5. The lifting cylinder 11 is vertically installed at the bottom of the support platform 10. The telescopic shaft of the lifting cylinder 11 passes through the through hole 12 to connect the lifting plate 3.

[0028] Embodiment 5

[0029] Based on the fourth embodiment, Figure 1 and Figure 2As shown, two groups of hollow stacking boxes 2 are arranged at intervals, and the two groups of hollow stacking boxes 2 are connected together by a rotating plate 13. A main shaft 14 is fixed in the middle of the rotating plate 13, and the main shaft 14 is rotatably connected to the support platform 10. A motor 15 is installed at the bottom of the support platform 10, and the output shaft of the motor 15 is connected to the main shaft 14. Through rotation, the two groups of hollow stacking boxes 2 are alternately located directly below the loading window 5. After the wood boards in the hollow stacking boxes 2 are polished, it is necessary to reuse the gantry mechanism to clamp the stacked wood boards and put them into the hollow stacking boxes 2, or The workers manually stack the wooden boards in the hollow stacking boxes 2. To avoid the loading process of the hollow stacking boxes 2 reducing production efficiency, two groups of hollow stacking boxes 2 are set up. One group of hollow stacking boxes 2 is used for loading and grinding wooden boards, and the other group of empty hollow stacking boxes 2 is used for loading wooden boards. After the loading of wooden boards in the hollow stacking boxes 2 is completed, the motor 15 drives the main shaft 14 to rotate, and the main shaft 14 drives the rotating plate 13 to rotate 180°, so that the two hollow stacking boxes 2 are switched in position, and the alternating loading and grinding operations are realized, thereby improving the grinding efficiency. It should be noted that the conveying frame of the conveyor belt 26 needs to avoid the hollow stacking boxes 2. An avoidance groove can be opened at one end of the conveyor belt 26 close to the hollow stacking box 2, so that the hollow stacking box 2 can rotate 180° so that it will not interfere with the conveyor belt 26.
