Most log grinding and polishing devices place the wood on a transmission belt when working. The conveyor belt carries the wood through the polishing roller to achieve grinding and polishing of the wood surface.
[0003] However, when most of the existing log grinding and polishing devices are used to polish wood, the devices themselves do not have a structure for turning the wood over, so that after the upper end surface of the wood is polished by the grinding roller, the worker needs to turn the wood over so as to polish the other rough surface. In addition, after the wood on the conveyor belt is polished, it moves to the other end of the conveyor belt, and the worker needs to catch the wood at the other end. Therefore, the efficiency of grinding and polishing is greatly affected.
[0004] Therefore, a log grinding and polishing device is proposed. Utility Model Content

[0024] like Figures 1 to 4 As shown, a specific embodiment of the utility model provides a log grinding and polishing device, including an operating table 1 and a grinding roller 2 arranged at the top of the operating table 1, a conveying device is arranged at the top of the operating table 1, a bracket 3 is fixedly connected to one side of the operating table 1, and a flipping assembly for turning over the wood board is arranged on the bracket 3. By setting the flipping assembly, the wood can be turned over, which is convenient for grinding and polishing the other side, thereby eliminating the need for workers to manually turn the wood, saving time and effort, and improving the grinding and polishing efficiency of the wood. The flipping assembly includes a first flip plate 4 and a second flip plate 5 arranged on one side of the operating table 1, a plurality of accommodating grooves 6 are opened on the first flip plate 4 and the second flip plate 5, and a rotating rod 7 is arranged between the first flip plate 4 and the second flip plate 5, and a plurality of limit boxes 8 are fixedly installed on the second flip plate 5.
[0025] like Figure 1 and Figure 4 As shown, specifically, the conveying device includes a conveyor belt 9 and a recovery belt 10 arranged on the top of the operating table 1, and the conveyor belt 9 and the recovery belt 10 move in opposite directions to each other, and rollers 11 are provided on the conveyor belt 9 and the recovery belt 10. The operating table 1 is provided with a driving member for rotating the conveyor belt 9, the recovery belt 10 and the roller 11. When the wood is polished, the driving member drives the roller 11, the conveyor belt 9 and the recovery belt 10 to rotate together. The driving member provides power for the rotation, which is the prior art and is not described in detail. A bracket 12 is fixedly connected to the bracket 3, and two rotating tubes 13 are rotatably connected to the bracket 12, and the two rotating tubes 13 are rotatably connected to the rollers 11 on the conveyor belt 9 and the recovery belt 10 respectively with belts 14. The rotation of the roller 11 drives the rotating tube 13 on the bracket 12 through the belt 14. The wood is placed on the conveyor belt 9, and the wood moves with the conveyor belt 9 to the bottom end of the grinding roller 2, so that the wood is grinded and polished by the grinding roller 2, and then the top surface of the wood is conveyed to the other end by the conveyor belt 9 after being grinded and polished. At this time, the wood continues to gradually enter the receiving groove 6 on the first flip plate 4 under the drive of the conveyor belt 9, and slides into the receiving groove 6 in the second flip plate 5 with the cooperation of the rotating rotating tube 13. Several limit boxes 8 correspond to several receiving grooves 6 respectively, until the end of the wood finally enters the limit box 8 corresponding to the receiving groove 6, and stops moving under the action of the limit box 8. A partition plate 15 is provided between the conveyor belt 9 and the recovery belt 10. The setting of the partition plate 15 enables the conveyor belt 9 and the recovery belt 10 to limit the wood during the movement of the wood to prevent its position fluctuation.
[0026] like Figure 1 and Figure 2As shown, specifically, the rotating rod 7 is fixedly connected to the limit plate 16, and one side of the rotating rod 7 and the limit plate 16 is fixedly connected with a round block 17, the rotating rod 7 and the limit plate 16 are fixedly connected to the first flip plate 4, and the rotating rod 7 and the limit plate 16 are slidably connected to the second flip plate 5, and the round block 17 is fixedly connected to the connecting rod 20, and a divider 21 is fixedly installed on the bracket 3, and the connecting rod 20 is fixedly connected to the divider 21. After the wood is in the limit box 8, at this time, the wood is located in the accommodating groove 6 and is between the first flip plate 4 and the second flip plate 5, and then the divider 21 is started, and the divider 21 rotates ninety degrees and then rotates ninety degrees again, so that the divider 21 passes The connecting rod 20 causes the round block 17 to rotate, and the rotation of the round block 17 drives the rotating rod 7 to rotate. With the cooperation of the limit plate 16, the rotating rod 7 drives the first flip plate 4 and the second flip plate 5 to rotate one hundred and eighty degrees. At this time, the wood between the first flip plate 4 and the second flip plate 5 follows the reversal, thereby realizing flipping. At this time, the wood at the rear end of the conveyor belt 9 is driven by the first flip plate 4 and the second flip plate 5 to be located at the rear end of the recovery belt 10. At this time, the turned wood is moved under the action of the rotating tube 13 and the recovery belt 10. After being polished by the grinding roller 2, the moved wood returns to the end where the wood was originally placed under the action of the recovery belt 10, and can then be caught by the workers.
[0027] like Figure 1 and Figure 4 As shown, specifically, a threaded rod 18 is rotatably connected to the round block 17, and the threaded rod 18 is threadedly connected to the second flip plate 5, and a rotating block 19 is fixedly connected to the end of the threaded rod 18, and a hexagonal hole is opened in the rotating block 19. The rotating block 19 can be driven to rotate by inserting an hexagonal wrench into the hexagonal hole and rotating it, thereby rotating the threaded rod 18, and then the second flip plate 5 can be moved with the cooperation of the rotating rod 7. The movement of the second flip plate 5 can change the distance between it and the first flip plate 4, thereby adjusting the distance between the first flip plate 4 and the second flip plate 5 to adapt to wood of different lengths.
