[0032] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0033] like Figures 1-7As shown, the epoxy floor polishing machine of the present invention includes a polishing machine housing 1, a cover 2 fixedly installed on the polishing machine housing 1, a controller 34 provided on the cover 2, and a polishing mechanism, an adjustment mechanism, and a cleaning mechanism. The polishing mechanism is located between the polishing machine housing 1 and the cover 2. The polishing mechanism includes a rotating component located between the polishing machine housing 1 and the cover 2.

The worm gear 9 is fixed to the output end of the drive motor 8 via a keyway, and the worm wheel 10 is fixed to the upper end of the first rotating frame 3 via a keyway.

[0035] Specifically, by controlling the operation of the drive motor 8, the output end of the drive motor 8 can drive the worm gear 9 to rotate. The worm gear 9, in cooperation with the worm wheel 10, drives the first rotating frame 3 to rotate. The first rotating frame 3 can drive the first polishing wheel 4 to rotate. At the same time, the first rotating frame 3, through the connecting arm 5, can drive the second rotating frame 6 to rotate. The second rotating frame 6 can drive the second polishing wheel 7 to rotate. Using one drive motor 8 to drive two polishing wheels can increase the polishing area of ​​the device and further improve the user's work efficiency.

[0036] In this embodiment, the adjustment mechanism is set on the polishing machine housing 1. The adjustment mechanism includes a U-shaped handrail frame 11 fixedly installed on the polishing machine housing 1. An extension component is provided on the U-shaped handrail frame 11.

A U-shaped handrail glove 14 is slidably installed on the U-shaped handrail frame 11. Two sets of positioning holes 15 adapted to the positioning bolts 13 are symmetrically opened on the U-shaped handrail glove 14.

[0037] Specifically, by unscrewing the positioning bolt 13 out of the positioning hole 15 at the current position, the U-shaped handrail 14 is pulled so that it can move along the U-shaped handrail frame 11, and the distance between the U-shaped handrail 14 and the U-shaped handrail frame 11 can be adapted to the user's arm length. The positioning bolt 13 is then screwed into the positioning hole 15 at the appropriate position, thus making it convenient for people of different arm lengths to use.

[0038] In this embodiment, the cleaning mechanism is disposed between the polishing machine housing 1, the cover 2, and the drive assembly. The cleaning mechanism includes a protective component disposed on the polishing machine housing 1. A sweeping component is disposed between the polishing machine housing 1, the cover 2, and the drive assembly. A collection component is disposed between the cover 2 and the protective component. The protective component includes a dustproof curtain 16 and a first sweeping brush 17 fixedly mounted on the polishing machine housing 1. The sweeping component includes a protective shell 18 fixedly mounted on the polishing machine housing 1. A first gear 19 rotatably connected to the protective shell 18 is fixedly mounted on the worm gear 9. A second gear 20 meshing with the first gear 19 is rotatably mounted on the inner side of the protective shell 18. A reciprocating threaded rod 21 is fixedly mounted on the second gear 20. A limit sleeve 22 is fixedly mounted on the cover 2. A threaded rod 21 is screwed onto the reciprocating threaded rod 21. A threaded transmission rod 23 is installed and slidably connected to the limiting sleeve 22. A fixing block 24 is fixedly installed on the dust curtain 16. A support frame 25 is fixedly installed on the threaded transmission rod 23 and slidably connected to the fixing block 24. A movable plate 26 is rotatably installed at the end of the support frame 25 by installing two torsion springs. A second cleaning brush 27 is fixedly installed on the movable plate 26. A fixing sleeve 28 is fixedly installed on the first cleaning brush 17. A plurality of springs 29 are connected to the inner wall of the fixing sleeve 28. The ends of the plurality of springs 29 are connected to an abutment strip 30 that slidably connects to the fixing sleeve 28. The collection assembly includes a vacuum cleaner 31 set on the cover 2. A collection hopper 33 adapted to the second cleaning brush 27 is fixedly installed on the dust curtain 16. A conveying pipe 32 is connected between the vacuum cleaner 31 and the collection hopper 33.

[0039] The dust curtain 16 is made of wear-resistant rubber; the first cleaning brush 17 is made of nylon bristles. The upper end of the dust curtain 16 is fixed to the polishing machine housing 1 around its perimeter by pressure strips and screws; the first cleaning brush 17 is fixed to the bottom edge of the polishing machine housing 1 by bolts. The dust curtain 16 and the first cleaning brush work together to wrap the first polishing wheel 4 and the second polishing wheel 7; the second cleaning brush 27 is fixed to the lower end of the movable plate 26 by screws. The second cleaning brush 27 consists of bristles and a brush plate. The bristles are made of polypropylene material, and the brush plate is made of aluminum alloy. The vacuum cleaner 31 is fixed to the top of the cover 2 by bolts; the collection hopper 33 is fixed to the inside of the dust curtain 16 by screws.

[0040] Specifically, by setting up a dust curtain 16 and a first cleaning brush 17, the splashing of polishing waste can be limited. The first cleaning brush 17 can clean up the waste. By controlling the rotation of the worm gear 9, the worm gear 9 can drive the first gear 19 to rotate. The first gear 19, through meshing with the second gear 20, can drive the reciprocating threaded rod 21 to rotate. The threaded transmission rod 23 moves along the inner side of the limiting sleeve 22 under the action of the thread of the reciprocating threaded rod 21. The threaded transmission rod 23 can drive the support frame 25 to move along the inner side of the fixed block 24. The support frame 25 can drive the second cleaning brush 27 to move through the movable plate 26. The second cleaning brush 27 can sweep the waste cleaned by the first cleaning brush 17 to the inner side of the collection hopper 33. By controlling the operation of the vacuum cleaner 31, the vacuum cleaner 31 can perform vacuuming work on the waste in the collection hopper 33 through the conveying pipe 32, thereby processing the waste generated by polishing.

[0041] When the movable plate 26 drives the second cleaning brush 27 to move towards the collection hopper 33, the movable plate 26 can press the abutment strip 30 into the inner side of the fixed sleeve 28. When the movable plate 26 separates from the abutment strip 30, the spring 29 can use its own elastic force to drive the abutment strip 30 out of the inner side of the fixed sleeve 28. When the movable plate 26 drives the second cleaning brush 27 to move in the opposite direction towards the collection hopper 33, the abutment strip 30 can abut against the movable plate 26 to rotate, so that the movable plate 26 can rotate under the support of the torsion spring of the support frame 25. When the movable plate 26 separates from the abutment strip 30, the torsion spring can drive the movable plate 26 to reset and rotate, so as to repeat the cleaning work.

[0042] Working principle: By unscrewing the positioning bolt 13 out of the positioning hole 15 at the current position, the U-shaped handrail 14 is pulled, allowing it to move along the U-shaped handrail frame 11. The distance between the U-shaped handrail 14 and the U-shaped handrail frame 11 is adjusted to fit the user's arm length. The positioning bolt 13 is then screwed into the positioning hole 15 at the appropriate position. The user can then move the polishing machine housing 1 using the U-shaped handrail 14 and the U-shaped handrail frame 11. Controlling the drive motor 8 causes its output to drive the worm gear 9 to rotate. The worm gear 9, in conjunction with the worm wheel 10, drives the first rotating frame 3 to rotate, which in turn drives the first polishing wheel 4 to rotate. Simultaneously, the first rotating frame 3, through the connecting arm 5, drives the second rotating frame 6 to rotate, allowing the second rotating frame 6 to... The second polishing wheel 7 is driven to rotate, and a drive motor 8 drives the two polishing wheels to rotate for polishing. The worm gear 9 can drive the first gear 19 to rotate, so that the first gear 19 can drive the reciprocating threaded rod 21 to rotate through the meshing action of the second gear 20. The threaded transmission rod 23 moves along the inner side of the limiting sleeve 22 under the action of the thread of the reciprocating threaded rod 21. The threaded transmission rod 23 can drive the support frame 25 to move along the inner side of the fixed block 24, so that the support frame 25 can drive the second cleaning brush 27 to move through the movable plate 26. The second cleaning brush 27 can sweep the waste swept by the first cleaning brush 17 to the inner side of the collection hopper 33. By controlling the operation of the vacuum cleaner 31, the vacuum cleaner 31 can perform vacuuming work on the waste in the collection hopper 33 through the conveying pipe 32.
