[0002] Wood processing, using wood as raw material, is mainly processed by mechanical or chemical methods, and its products still retain the basic characteristics of wood. When processing wood, the surface of the rough wood is usually very rough, and further grinding and polishing are required before it can be used normally, so a polishing machine is needed;

[0003] When using a polishing machine to polish wood, especially wooden boards, after polishing a wooden board, it is impossible to continue polishing subsequent wooden boards due to the process of disassembling and assembling the wooden boards. In this process, a lot of time will be wasted, resulting in poor wood processing efficiency. In addition, a large amount of dust will be generated in the process of polishing the wooden boards. The dust will float into the air in large quantities, causing the quality of the working environment to decline. The dust is not only difficult to clean, but also affects the health of the staff.

[0014] Compared with the prior art, the utility model achieves the following beneficial effects:

[0015] 1.

DETAILED DESCRIPTION

[0024] A polishing machine for wood processing:

[0025] like Figure 1-3As shown, in this embodiment, it includes a body 1 and a polishing table 2, the polishing table 2 is rotatably connected to the body 1, support blocks 3 are fixed on all sides of the outer periphery of the polishing table 2, support plates 4 are fixed on the outer ends of the support blocks 3, the left and right ends of the outer periphery of the support plate 4 are slidably sleeved with clamping plates 5, and the left and right ends of the inner side of the support plate 4 are fixed with fixed plates 7, a two-way threaded rod 6 is threaded through the left and right clamping plates 5, and the two-way threaded rod 6 rotates through the fixed plate 7 and the support block 3 on the same horizontal line, and a flip brake assembly is provided at the right end of the polishing table 2, the flip brake assembly includes a brake motor 8, a main gear 9, a rotating shaft 10 and a sub gear 11, the brake motor 8 is fixed to the inner wall of the body 1, the main gear 9 is connected to the power end of the brake motor 8, one end of the rotating shaft 10 is fixed to the right end of the polishing table 2, and the other end of the rotating shaft 10 is rotatably connected to the inner wall of the body 1, the sub gear 11 is fixedly sleeved on the outer periphery of the rotating shaft 10, and the sub gear 11 is meshed with the main gear 9.

[0026] When it is necessary to install the wooden board around the outer periphery of the polishing table 2, the wooden board is placed on the supporting plate 4, and then the two-way threaded rod 6 is twisted to drive the clamping plate 5 to clamp and fix the wooden board to prevent the wooden board from accidentally loosening during the polishing process. Therefore, a wooden board to be polished is installed around the outer periphery of the polishing table 2. When the polishing process of the previous wooden board is completed, the main gear 9, the sub-gear 11, the rotating shaft 10 and the polishing table 2 are driven to rotate through the operation of the brake motor 8. Therefore, the polishing table 2 is driven to rotate 90 degrees and stop each time in combination with the operation of the flip brake assembly. After the polishing table 2 rotates, it will drive the installed wooden board to rotate 90 degrees and stop together. Therefore, the next wooden board to be polished can continue to be polished. When it is necessary to remove the polished wooden board, the two-way threaded rod 6 is twisted to drive the clamping plate 5 to no longer clamp the wooden board. At this time, the polished wooden board can be removed, and then a new wooden board to be polished can be installed. This reciprocating process effectively saves the time wasted when disassembling and assembling the wooden board, so that the subsequent wooden boards can continue to be polished when disassembling and assembling the wooden board, effectively improving the polishing efficiency of the wooden board.

[0027] like Figure 1 , 4As shown in Figures 5 and 6, in this embodiment, a mounting plate 16 is provided above the polishing table 2, and a telescopic cover 17 is connected to the lower end of the mounting plate 16, and a protective cover 19 is connected to the lower end of the telescopic cover 17. A driving motor 21 located in the telescopic cover 17 and the protective cover 19 is fixed to the lower end of the mounting plate 16, and a polishing disc 22 is connected to the power end of the driving motor 21. At least two spring telescopic rods 18 distributed left and right are connected between the mounting plate 16 and the protective cover 19. A sliding frame 13 is slidably connected to the top end of the body 1, and an electric cylinder 15 is fixed to the lower end of the sliding frame 13. The mounting plate 16 is connected to the power end of the electric cylinder 15. A forward and reverse motor 12 is fixed to the right end of the body 1, and a screw rod 14 is connected to the power end of the forward and reverse motor 12. The screw rod 14 threadedly passes through the sliding frame 13, and the other end of the screw rod 14 is rotatably connected to the left wall of the body 1, and a plurality of balls 20 are rotatably connected to the lower end of the protective cover 19.

[0028] When it is necessary to polish the wooden board, the driving motor 21 drives the polishing disc 22 to rotate, and at the same time, the electric cylinder 15 drives the mounting plate 16, the telescopic cover 17, the protective cover 19, the driving motor 21 and the polishing disc 22 to move downward together, and the ball 20 will be pressed on the wooden board. When the mounting plate 16 continues to move downward, the protective cover 19 will compress the telescopic cover 17 and the spring telescopic rod 18 until the polishing disc 22 can be polished to the surface of the wooden board. Then, the screw rod 14 is driven to rotate by the work of the forward and reverse motors 12, and the screw rod 14 will drive the sliding frame 13 to slide back and forth along the body 1, so the sliding frame 13 will drive the electric cylinder 15, the mounting plate 16, the telescopic cover 17, the protective cover 19, the driving motor 21 and the polishing disc 22 to move left and right together, and at the same time, the protective cover 19 will drive the ball 20 to roll along the surface of the wooden board, which is beneficial to ensure the smoothness of the driving motor 21 and the polishing disc 22 when moving and polishing, and is therefore beneficial to comprehensively polishing the surface of the wooden board.

[0029] like Figure 1 , 5As shown in Figures 6, in this embodiment, the outer periphery of the driving motor 21 is sleeved with a first annular tube 23 fixed to the inner wall of the protective cover 19, the lower end of the first annular tube 23 is connected to a plurality of first dust hoods 24, the outer periphery of the protective cover 19 is fixedly sleeved with a second annular tube 25, the lower end of the second annular tube 25 is connected to a plurality of second dust hoods 26, the outer side of the protective cover 19 is provided with a dust suction power assembly, the dust suction power assembly includes a dust collector 29, a longitudinal telescopic tube 30, a transverse telescopic tube 28 and a dust suction pipe 27, the dust collector 29 is fixed to the outer wall of the body 1, the longitudinal telescopic tube 30 is connected to the dust suction port of the dust collector 29, the transverse telescopic tube 28 is connected to the lower end of the longitudinal telescopic tube 30, and the transverse telescopic tube 28 extends into the body 1, one end of the dust suction pipe 27 is connected to the transverse telescopic tube 28, and the dust suction pipe 27 runs through the protective cover 19, the first annular tube 23 is connected to the other end of the dust suction pipe 27, and the transverse telescopic tube 28 is connected to the second annular tube 25.

[0030] During the polishing process of the wood board, the polishing processing position of the polishing disc 22 is shielded by the cooperation of the protective cover 19 and the telescopic cover 17, and most of the dust will be gathered in the protective cover 19 and the telescopic cover 17. When the vacuum cleaner 29 is started, the first dust hood 24 will absorb the dust gathered in the protective cover 19 and the telescopic cover 17, and then absorb the dust into the vacuum cleaner 29 through the first annular tube 23, the dust suction tube 27, the transverse telescopic tube 28 and the longitudinal telescopic tube 30, and part of the dust overflowing the protective cover 19 will be absorbed by the second dust hood 26, and then absorbed into the vacuum cleaner 29 by the second annular tube 25, the transverse telescopic tube 28 and the longitudinal telescopic tube 30. When the cover 19 moves, it will drive the first annular tube 23, the second annular tube 25 and the dust suction tube 27 to move together. When the protective cover 19 moves up and down, it will drive the longitudinal telescopic tube 30 to extend and retract. When the protective cover 19 moves left and right, it will drive the transverse telescopic tube 28 to extend and retract. Therefore, it is beneficial to ensure the smoothness of the polishing disc 22 during the polishing process. In summary, through the cooperation of internal and external dust suction by several first dust suction covers 24 and second dust suction covers 26, it is beneficial to more comprehensively absorb and clean the dust generated by polishing, effectively solve the problem of dust flying everywhere, and reduce the trouble of cleaning dust in the later stage, thereby ensuring the environmental quality during work and reducing the impact of dust on the health of workers.
