[0024] The effect achieved by the entire embodiment 1 is that when the chamfering component 13 completes the chamfering operation on the kindergarten table and chair boards, the chamfering component 13 includes a control system, a moving mechanism, a driving mechanism and a grinding wheel, and then the forward and reverse motor 2 is started to drive the threaded rod 3 to rotate inside the strip column 4. Since a limit rod 7 is installed between the strip column 4 and the fixed block 6, and the movable plate 5 is movably sleeved on the limit rod 7, the movable plate 5 can move stably on the limit rod 7 and the threaded rod 3 at the same time, and move to the corresponding position of the grinding component 14, wherein the grinding component 14 includes a control system, a moving mechanism, a driving mechanism and a polishing tool, and grinds the kindergarten table and chair boards after chamfering, and there is no need for the staff to transfer them to another place for grinding, so that chamfering and grinding can be carried out simultaneously, which reduces the working time of the staff and improves the efficiency of chamfering and grinding the kindergarten tables and chairs.

[0025] Embodiment 2, as Figure 2-Figure 4 As shown, a chamfering assembly 13 is fixedly installed on the top of the operating panel 1, a grinding assembly 14 is fixedly installed on the top of the operating panel 1, a placement plate 15 is fixedly installed on the top of the toothed disc 12, two L-shaped frames 16 are fixedly installed on the top of the placement plate 15, the tops of the two L-shaped frames 16 are threadedly connected with screws 17, the tops of the two screws 17 are fixedly installed with handles 18, one side of the inner wall of the two L-shaped frames 16 is provided with a limiting groove 19, the inner surface walls of the two limiting grooves 19 are movably embedded with limiting sliders 20, the bottoms of the two screws 17 are rotatably connected with pressure plates 21, and one side of the outer wall of the two pressure plates 21 is fixedly connected to the opposite side of the outer wall of the two limiting sliders 20.

[0026] The effect achieved by the entire embodiment 2 is that, when in use, the kindergarten table and chair plate is placed on the placement plate 15, and then the handles 18 installed on the two screw rods 17 are rotated to drive the screw rods 17 to rotate downward. Since a pressing plate 21 is rotatably connected to the bottom of the screw rod 17, a limiting groove 19 is provided on one side of the inner wall of the two L-shaped frames 16, and the limiting sliders 20 installed on one side of the outer wall of the two pressing plates 21 are movably embedded in the two limiting grooves 19, so that the two pressing plates 21 can move downward stably and limit the kindergarten table and chair plate on the placement plate 15, thereby improving the stability of the rounding and grinding treatment. When one end of the pressing plate 21 is After completing the corresponding operations, start the driving motor 8 to drive the driving rod 9 and the gear 10 to rotate. Since the toothed disc 12 is rotatably connected to the rotating column 11, and the toothed disc 12 and the gear 10 are meshingly connected, the toothed disc 12 rotates on the rotating column 11 through the rotation of the gear 10. Since the placement plate 15 is fixedly mounted on the toothed disc 12, the placement plate 15 and the material thereon are driven to rotate until the other end of the material is in the corresponding position. The staff does not need to remove the material and replace it, which further reduces the staff's working time, thereby improving the efficiency of chamfering and polishing the preschool tables and chairs.

[0027] Working principle: First, when it is necessary to chamfer and polish the kindergarten table and chair boards, the material is first placed on the placement plate 15, and the two handles 18 and the two screws 17 are turned at the same time. Under the action of the two limit grooves 19 and the two limit sliders 20, the two pressure plates 21 are driven to move downward stably, so that the material can be limited on the placement plate 15, which improves the stability of subsequent operations. Then, the chamfering component 13 is used to chamfer the material. After the chamfering is completed, when it is necessary to polish it, the forward and reverse motors 2 are started. Since the movable plate 5 is threadedly connected to the threaded rod 3, and the movable plate 5 is also movably sleeved on the limit rod 7 installed between the bar column 4 and the fixed block 6, the threaded rod 3 is driven to rotate by the forward and reverse motors 2, so that the movable plate 5 is moved between the threaded rod 3 and the limit The positioning rod 7 moves on the positioning rod 7 until it is moved to the corresponding position of the grinding component 14, and is ground. Secondly, when one end of the material completes the corresponding operation, the driving motor 8 is started to drive the driving rod 9 and the gear 10 to rotate. Since the gear 10 and the toothed disc 12 are meshingly connected, and the toothed disc 12 is rotatably connected to the rotating column 11, the toothed disc 12 can be rotated on the rotating column 11 through the rotation of the gear 10, thereby driving the placement plate 15 and the material with the upper limit on the placement plate 15 to rotate, and the other end of the material is rotated to the corresponding position, and the corresponding chamfering and grinding are performed again. During the whole process, the staff does not need to move the material to another place for operation, which reduces the working time of the staff, thereby improving the efficiency of chamfering and grinding of preschool tables and chairs.
