[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This embodiment provides a technical solution: a surface polishing device for office desks, including a polishing table 1 and a lifting drive mechanism 4;

[0023] Grinding table 1: Guide rods 2 are fixedly connected to the four corners of its upper surface. Positioning seats 3 are slidably connected between two longitudinally adjacent guide rods 2. A control switch group 16 is set in the middle of the right side surface of the grinding table 1. The input end of the control switch group 16 is electrically connected to an external power supply. It also includes a grinding chamber 5. The grinding chamber 5 is set in the middle between two positioning seats 3. Three drive shafts 6 are rotatably connected inside the grinding chamber 5. Grinding wheels 9 are fixedly connected to the lower end of each drive shaft 6. Driven wheels 7 are fixedly connected to the upper ends of the leftmost drive shaft 6 and the rightmost drive shaft 6. Two drive wheels 8 are fixedly connected to the upper end of the middle drive shaft 6. Driven wheels 7 are connected to the laterally adjacent drive wheels 8 through a transmission belt. Fixed rollers 12 are evenly distributed inside the grinding table 1. Positioning rollers 11 are evenly distributed between the two positioning seats 3.

[0024] The lifting drive mechanism 4 includes a drive compartment 41, sliding seats 42, a drive handle 43, and a connecting shaft 44. Each drive compartment 41 is fixedly connected to the upper end between two horizontally adjacent guide rods 2. Each drive compartment 41 has a sliding opening at its lower end, and two sliding seats 42 are slidably connected inside each opening. The lower end of each sliding seat 42 is rotatably connected to a drive handle 43. The front and rear ends of the positioning seat 3 are fixedly connected to the connecting shaft 44. The middle part of each connecting shaft 44 is rotatably connected to the lower end of a vertically adjacent drive handle 43. The lowering drive mechanism 4 also includes a bidirectional screw 45, a drive gear 46, a driven gear 47, and a motor 48. The bidirectional screws 45 are all rotatably connected to the inside of the sliding port. The upper end of each sliding seat 42 is threadedly connected to the corresponding end of the vertically adjacent bidirectional screw 45. A driven gear 47 is fixedly connected to the middle of each bidirectional screw 45. A motor 48 is installed inside each drive chamber 41. A drive gear 46 is fixedly connected to the left end of each motor 48. Each drive gear 46 meshes with the longitudinally adjacent driven gear 47. The input terminals of motor 48 are electrically connected to the output terminals of control switch group 16. According to the required thickness of the office desk board to be polished, motor 48 is operated by control switch group 16. The output shaft of motor 48 rotates, which drives drive gear 46 to rotate. The rotation of drive gear 46 drives the longitudinally adjacent driven gear 47 to rotate. The rotation of driven gear 47 drives the transversely adjacent bidirectional screw 45 to rotate. The rotation of bidirectional screw 45 causes the two transversely adjacent sliding seats 42 to move away from the center of drive chamber 41 inside the corresponding sliding opening. The outward movement of sliding seats 42 causes the upper end of drive handle 43 to move away from the center of drive chamber 41. The lower end of drive handle 43 pushes the longitudinally adjacent positioning seat 3 to move down under the guidance of the corresponding guide rod 2 through the corresponding connecting shaft 44. The downward movement of positioning seat 3 causes positioning roller 11 and polishing chamber 5 to move down. The downward movement of polishing chamber 5 drives grinding wheel 9 to move down through drive shaft 6. Positioning roller 11 and fixed roller 12 work together to achieve stable clamping of office desk board.

[0025] The grinding chamber 5 is equipped with a second motor 10 at its upper end. The lower end of the output shaft of the second motor 10 is fixedly connected to the upper end of the vertically adjacent drive shaft 6. The input end of the second motor 10 is electrically connected to the output end of the control switch group 16. When the grinding wheel 9 contacts the surface of the office desk board, the control switch group 16 shuts off the first motor 48 and enables the second motor 10 to run. The rotation of the output shaft of the second motor 10 drives the vertically adjacent drive shaft 6 to rotate. The rotation of the drive shaft 6 drives the two drive wheels 8 to rotate. The drive wheels 8 drive the horizontally adjacent drive wheels 7 to rotate through the transmission belt 1. The rotation of the drive wheels 7 drives the vertically adjacent drive shaft 6 to rotate. The rotation of the drive shaft 6 drives the vertically adjacent grinding wheel 9 to rotate. The rotation of the grinding wheel 9 achieves the grinding of the surface of the office desk board.

[0026] The grinding table 1 has a motor 3 15 installed at the front end of the right side surface. The left end of the output shaft of the motor 3 15 is fixedly connected to the right end of the foremost fixed roller 12. The left end of the foremost fixed roller 12 is fixedly connected to the drive wheel 2 13, and the right end of the last fixed roller 12 is fixedly connected to the driven wheel 2 14. The drive wheel 2 13 and the driven wheel 2 14 are connected by a transmission belt 2. The input end of the motor 3 15 is electrically connected to the output end of the control switch group 16. The control switch group 16 enables the motor 3 15 to operate. The rotation of the output shaft of the motor 3 15 drives the adjacent horizontal fixed roller 12 to rotate. The rotation of the foremost fixed roller 12 drives the drive wheel 2 13 to rotate. The rotation of the drive wheel 2 13 drives the driven wheel 2 14 to rotate through the transmission belt 2. The rotation of the driven wheel 2 14 drives the last fixed roller 12 to rotate, thereby realizing the transfer of the surface of the office desk board and thus realizing the continuous grinding of the surface of the office desk board.

[0027] The working principle of the surface polishing device for office desks provided by this utility model is as follows: During operation, the operator first places the polishing table 1, polishing chamber 5, and other mechanisms stably in a horizontal working area. After stable placement, the operator, according to the required thickness of the office desk board to be polished, controls the switch group 16 to activate motor 48. The output shaft of motor 48 rotates, driving the drive gear 46 to rotate. The rotation of drive gear 46 drives the longitudinally adjacent driven gear 47 to rotate. The rotation of driven gear 47 drives the transversely adjacent bidirectional screw 45 to rotate. The rotation of bidirectional screw 45 causes the two transversely adjacent sliding seats 42 to move away from the center of drive chamber 41 within their corresponding sliding openings. The outward movement of sliding seats 42 causes the upper end of drive handle 43 to move away from the center of drive chamber 41. This causes the lower end of drive handle 43 to push the longitudinally adjacent positioning seat 3 downward under the guidance of the corresponding guide rod 2 via the corresponding connecting shaft 44. The downward movement of positioning seat 3 causes the positioning roller 11 and polishing chamber 5 to move downward. The downward movement of polishing chamber 5 drives the grinding wheel 9 downward via drive shaft 6. The positioning roller 11 and the fixed roller 12 work together to achieve stable clamping of the office desk board. When the grinding wheel 9 contacts the surface of the office desk board, the control switch group 16 shuts off motor 48 and starts motor 10. The output shaft of motor 10 rotates, driving the vertically adjacent drive shaft 6 to rotate. The drive shaft 6 rotates, driving the two drive wheels 8 to rotate. Each drive wheel 8 drives the horizontally adjacent drive wheel 7 to rotate via the transmission belt 1. The rotation of drive wheel 7 drives the vertically adjacent drive shaft 6 to rotate. The rotation of drive shaft 6 drives the vertically adjacent grinding wheel 9 to rotate. The rotation of grinding wheel 9 achieves the grinding of the surface of the office desk board. At the same time, the control switch group 16 starts motor 15. The output shaft of motor 15 rotates, driving the horizontally adjacent fixed roller 12 to rotate. The rotation of the foremost fixed roller 12 drives the drive wheel 13 to rotate. The rotation of drive wheel 13 drives the driven wheel 14 to rotate via the transmission belt 2. The rotation of driven wheel 14 drives the last fixed roller 12 to rotate, realizing the transfer of the office desk board surface and thus achieving continuous grinding of the office desk board surface.

[0028] It is worth noting that the control switch group 16 disclosed in the above embodiments is provided with control buttons that correspond one-to-one with motor 1 48, motor 2 10 and motor 3 15 and control their switching.
