[0034] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0035] Example 1

[0036] Please refer to Figures 1-7As shown, a bottom surface grinding device for a plastic runway includes a base plate 1, slide rails 2 are provided on both sides of the upper end of the base plate 1, support rods 3 are slidably connected inside the slide rails 2 on both sides, and moving parts 4 are provided on the upper sides of the support rods 3 on both sides. A support platform 5 is provided on the upper side of the base plate 1, and the lower side of the support platform 5 is fixedly connected to the base plate 1 through a support column 6. An impurity removal mechanism 7 is provided on the lower side of the support platform 5, a gantry 8 is fixedly connected to the upper side of the base plate 1, and fixing mechanisms 9 are provided on the corresponding sides of the gantry 8. Vertical moving mechanisms 10 are provided on the left and right sides of the gantry 8, a horizontal moving mechanism 11 is provided on the lower side of the vertical moving mechanism 10, and a driving mechanism 12 is provided in the middle of the horizontal moving mechanism 11.

[0037] In this embodiment, the plastic track can be moved to the left by the slide rail 2, the support rod 3 and the moving part 4. The impurity removal mechanism 7 and the external wind mechanism can shake up and blow away the particles on the plastic track. Secondly, the fixing mechanism 9 can fix and clamp the plastic track to prevent the movement of the plastic track when the bottom surface of the plastic track is polished, thereby affecting the polishing effect. Finally, the driving mechanism 12 is lowered to the designated location by the vertical moving mechanism 10. Then, the bottom of the plastic track can be polished back and forth continuously by the horizontal moving mechanism 11 and the driving mechanism 12, thereby increasing its polishing effect.

[0038] Please refer to Figure 3 As shown, the impurity removal mechanism 7 includes a first servo motor 701, the output end of the first servo motor 701 is fixedly connected to a worm gear 702, the upper side of the base plate 1 is fixedly connected to a fixed column 703, the outer surface of the fixed column 703 is fixedly connected to a fixing member 704, the end of the fixing member 704 away from the fixed column 703 is fixedly connected to a fixed ring plate 705, a cavity is provided inside the fixed column 703, and a tension spring 706 is fixedly connected to the lower side of the inner wall of the fixed column 703, a sliding column 707 is fixedly connected to the upper side of the tension spring 706, a plurality of notches 708 are provided on the outer surface of the sliding column 707, and the notches 708 are meshed with the worm gear 702.

[0039] In this embodiment, the first servo motor 701 is turned on, and the first servo motor 701 drives the worm gear 702 to rotate. Since the worm gear 702 is engaged with the notch 708 on the sliding column 707, the sliding column 707 can be driven to be ejected upward. When the worm gear 702 is not engaged with the sliding column 707, the sliding column 707 slides downward due to the tension of the tension spring 706. As the first servo motor 701 drives the worm gear 702 to rotate continuously, the bottom of the plastic runway can be continuously ejected, thereby shaking off the particles on the outer surface of the bottom of the plastic runway, and then the particles are removed by an external wind mechanism, thereby further increasing the polishing effect on the bottom of the plastic runway.

[0040] Example 3

[0041] Please refer toFigure 4 As shown, the fixing mechanism 9 includes an upper connecting plate 901, and the number of the upper connecting plates 901 is two, and the two upper connecting plates 901 are fixedly connected to the outer surface of the gantry 8, a second servo motor 902 is installed on the upper side of the left upper connecting plate 901, the output end of the second servo motor 902 passes through the left upper connecting plate 901, and is fixedly connected to the first threaded rod 903, the corresponding two sides of the outer surface of the gantry 8 are fixedly connected to the lower connecting plates 904, the lower side of the first threaded rod 903 is rotatably connected to the left lower connecting plate 904, the side upper connecting plate 901 and the middle part of the lower connecting plate 904 are fixedly connected with the first sliding rod 905, the outer surface of the first threaded rod 903 is threadedly connected to the internal thread block 906, the outer surface of the first sliding rod 905 is slidably connected to the sliding block 907, and the internal thread block 906 and the middle part of the sliding block 907 are fixedly connected to the first connecting plate 908.

[0042] In this embodiment, when the plastic track is moved to the designated location, the second servo motor 902 is turned on, and the second servo motor 902 drives the internal thread block 906 to rotate through the first threaded rod 903. Since the internal thread block 906 slides on the outer surface of the first slide rod 905 through the first connecting plate 908 and the sliding block 907, the first connecting plate 908 can be pressed down vertically, so that the two sides of the plastic track can be clamped and fixed, which can avoid the problem of the plastic track moving during the grinding process, thereby affecting the grinding effect.

[0043] Example 4

[0044] Please refer to Figure 5 As shown, the vertical moving mechanism 10 includes a support plate 1001, which is fixedly connected to the gantry 8.

The second threaded rods 1006 on both sides are rotatably connected to the inner wall of the gantry 8. The second threaded rods 1006 on both sides are fixedly connected with second sliding rods 1007 on corresponding sides. The second threaded rods 1006 on both sides are threadedly connected to second connecting plates 1008, and the second connecting plates 1008 are slidingly connected to the four second sliding rods 1007.

[0045] In this embodiment, the third servo motor 1002 is started, and the output end of the third servo motor 1002 can drive the second threaded rods 1006 on both sides to rotate through the driving wheel 1003, the belt 1004 and the driven wheel 1005. Since the second threaded rods 1006 are threadedly connected to the second connecting plate 1008, and the second sliding rods 1007 on both sides of each second threaded rod 1006 are slidingly connected to the second connecting plate 1008, the second connecting plate 1008 can be driven to move downward.

[0046] Example 5

The right side of the grinding roller 1202 is rotatably connected to the connecting member 1203, and the connecting member 1203 is slidably connected to the third slide bar 1104.

[0048] In this embodiment, the fifth servo motor 1201 is first turned on, and the fifth servo motor 1201 drives the grinding roller 1202 to rotate, so that the bottom of the plastic runway can be polished. At the same time, the fourth servo motor 1102 is turned on, and the fourth servo motor 1102 can drive the load-bearing plate 1105 threadedly connected to the third threaded rod 1103 to rotate, and the load-bearing plate 1105 slides in the third slide rod 1104 through the fifth servo motor 1201 and the connecting member 1203, which can limit the rotation direction of the load-bearing plate 1105, thereby driving the load-bearing plate 1105 to move horizontally.
