[0024] refer to Figure 1-3 As shown, one embodiment of the utility model is:

[0025] A device for efficiently grinding burrs of a plate comprises grinding tables 1 arranged at intervals, a plate steering mechanism is arranged between two grinding tables 1, a feed roller 2 and a discharge roller 3 are arranged on the grinding tables 1 in sequence along the plate conveying direction, grinding holes 4 are symmetrically opened on both sides of the grinding table 1, the grinding holes 4 are located between the feed roller 2 and the discharge roller 3, a grinding mechanism is installed on the outer side wall of the grinding hole 4, a limiting guide plate 5 is relatively arranged on the latter grinding table 1, and the limiting guide plate 5 is located between the feed roller 2 and the plate steering mechanism.

[0026] Specifically, the limiting guide plate 5 is located on the feeding side of the feeding roller 2 on the rear grinding table, and the plate steering mechanism includes a first conveyor belt 6 and a second conveyor belt 7 which are staggered. The first conveyor belt 6 is arranged close to the front grinding table 1, and the second conveyor belt 7 is arranged close to the rear grinding table 1. A support shaft 8 is provided in the middle of the second conveyor belt 7, and the support shaft 8 is used to support the middle part of the second conveyor belt 7 to bulge upward, and the running speed of the second conveyor belt 7 is greater than the running speed of the first conveyor belt 6.

[0027] The front grinding table grinds the two opposite sides of the plate. Under the action of the plate turning mechanism, the plate turns 90 degrees and enters the rear grinding table. The rear grinding table grinds the remaining two opposite sides of the plate. The four sides of the plate can be polished without manually turning the direction of the plate, and the grinding efficiency is high.

[0028] In the specific implementation, the running speed difference between the first conveyor belt 6 and the second conveyor belt 7 is adjusted according to the size of the plate, so as to realize the plate turning 90°. At the same time, in order to ensure that the plate enters the next grinding table after turning 90°, a limiting guide plate 5 is provided on the next grinding table in this embodiment. Figure 1 As shown, the two limiting guide plates 5 are in a trumpet-mouth structure to limit and guide the plate, thereby ensuring that the plate can be turned 90 degrees before subsequent grinding operations.

[0029] The support shaft 8 is set to make the second conveyor belt 7 and the first conveyor belt 6 have a certain height difference, so that the middle of the plate being conveyed is suspended in the air, reducing the contact surface between the plate and the conveyor belt, reducing friction, and better realizing the turning of the plate. In specific implementation, the height difference between the two conveyors should not be too large to prevent the plate from falling off.

[0030] Furthermore, the grinding mechanism includes a U-shaped mounting plate 9, a first driving screw 10, an electric telescopic rod 11, a grinding motor 12, and a grinding wheel 13. The first driving screw 10 is penetrated on the outer wall of the grinding hole 4, and the end of the first driving screw 10 is rotatably connected to the bottom plate of the U-shaped mounting plate 9. The electric telescopic rod 11 is relatively installed on the two side plates of the U-shaped mounting plate 9, and the movable end of the electric telescopic rod 11 is fixedly installed with the grinding motor 12. The grinding wheel 13 is installed at the power output end of the grinding motor 12. The outer wall of the grinding hole 4 is provided with a vertical positioning mechanism adapted to the U-shaped mounting plate 9.

[0031] Specifically, the vertical positioning mechanism includes a positioning plate 14 and a positioning plate 15. The positioning plate 14 is fixedly connected to the outer wall of the grinding hole 4. A positioning hole is opened on the positioning plate 14. The positioning plate 15 is connected to the bottom plate of the U-shaped mounting plate 9, and the positioning plate 15 is passed through the positioning hole.

[0032] In a specific implementation, the positioning plates 14 are provided at both upper and lower ends of the outer side wall of the grinding hole 4 to improve stability.

[0033] The feed roller 2 and the discharge roller 3 are both connected to a drive motor 16 .

[0034] The first driving screw 10 is used to adjust the position of the U-shaped mounting plate 9 in the grinding hole 4, so as to adapt to the grinding plates of different sizes. By setting the U-shaped mounting plate 9 and arranging the electric telescopic rod 11, the grinding motor 12, and the grinding wheel 13 on the two side plates, it is possible to grind both sides of the plate at the same time, thereby improving the grinding efficiency.

[0035] The integrated structure of the U-shaped mounting plate 9 is adopted to improve the grinding stability. Further, in this embodiment, a guide rail (not shown in the figure) is provided on the bottom plate of the U-shaped mounting plate 9, and a slider 17 adapted to the guide rail is provided on the grinding motor 12. The provided slider 17 cooperates with the guide rail to improve stability and reduce the shaking effect of the grinding motor 12 on the electric telescopic rod 11.

[0036] Furthermore, a plate guide and limit mechanism is provided on the outer side wall of the grinding hole 4, and the plate guide and limit mechanism is located between the feeding roller 2 and the grinding mechanism.

[0037] The plate guide and limit mechanism includes a second drive screw 18 and a guide limit block 19. The second drive screw 18 is passed through the outer wall of the grinding hole 4. The end of the second drive screw 18 is connected to the guide limit block 19. The guide limit block 19 is provided with a guide groove (not shown in the figure).

[0038] The second driving screw 18 and the guide limit block 19 arranged in the grinding hole are used to guide and limit the plate to be ground, so that the edge of the plate passes through between the two grinding wheels 13, ensuring that the grinding operation proceeds normally.

[0039] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
