[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] See also Figures 1-8, A grinding device for the column grooves on the surface of a fiberboard shown in the figure, including a support frame 1. Inside the support frame 1, two support blocks 2 are slidably installed. Above the support frame 1, there is a frame 26. At both ends below the frame 26, driving wheels 29 are rotatably installed. Inside the frame 26, a pressing plate 10 is installed through a sliding structure. Inside the pressing plate 10, a groove 34 is formed, and inside the groove 34, a protrusion 35 is provided. The support block 2 is connected to the pressing plate 10 through a moving mechanism. Above the support block 2, a mounting block 30 is fixedly installed, and the mounting block 30 is connected to the protrusion 35 through a limiting mechanism. Inside the support block 2, a rotating shaft 4 is rotatably installed. Outside the rotating shaft 4, a rotating mechanism is provided. Below the rotating shaft 4, a grinding piece 3 is detachably installed.

[0029] The sliding structure includes a chute 27 and a slider 28. The chute 27 is formed inside the frame 26, and the slider 28 is slidably inserted into the chute 27. The slider 28 is fixedly connected to the pressing plate 10.

[0030] Specifically, place the support frame 1 on the surface of the fiberboard so that the grinding piece 3 is inside the column groove. The pressing plate 10 moves downward. The pressing plate 10 drives the two support blocks 2 to move away from each other through the moving mechanism. The support block 2 drives the rotating shaft 4 and the grinding piece 3 to move synchronously. After the two grinding pieces 3 contact the inner walls on both sides of the column groove respectively, they stop moving. When the mounting block 30 passes through the groove 34, the mounting block 30 is connected to the protrusion 35 through the limiting mechanism, and the support block 2 and the pressing plate 10 can be regarded as an integral body. The rotating mechanism drives the grinding piece 3 to rotate through the rotating shaft 4 to grind the inner wall of the column groove. Under the action of the driving wheel 29, the frame 26 moves along the surface of the fiberboard. When the column groove is designed in a wave shape, the frame 26 drives the support frame 1 to move, and the support frame 1 can drive the pressing plate 10 and the slider 27 to move inside the chute 28, so as to adapt to the shape of the column groove, making the application range of the device wider. Moreover, when moving, the distance between the two grinding pieces 3 is fixed, and the width of the column groove can be checked during grinding.

[0031] The moving mechanism includes an adjusting plate 5. The adjusting plate 5 is connected to the support frame 1 through a reset structure. The adjusting plate 5 is connected to the support block 2 through an elastic structure. Above the adjusting plate 5, a push plate 11 is rotatably installed. One end of the push plate 11 away from the adjusting plate 5 is rotatably connected to the pressing plate 10.

[0032] The reset structure includes a cross bar 8 and a second spring 9. The cross bar 8 is fixedly inserted into the support frame 1. The cross bar 8 is slidably connected to the adjusting plate 5. The second spring 9 is movably sleeved outside the cross bar 8, and the second spring 9 is fixedly connected to the adjusting plate 5.

[0033] The elastic structure includes a rod 6. The rod 6 slidably penetrates the adjusting plate 5. The rod 6 is fixedly connected to the support block 2. The first spring 7 is movably sleeved outside the rod 6, and the first spring 7 is fixedly connected to the adjusting plate 5.

[0034] Further, the pressing plate 10 moves towards the support frame 1, driving the push plate 11 to rotate. The push plate 11 pushes the adjusting plate 5 to move horizontally inside the support frame 1. The two groups of adjusting plates 5 move away from each other. The adjusting plate 5 drives the support block 2 to move synchronously through the rod member 6. At this time, the adjusting plate 5 slides outside the cross bar 8, and the second spring 9 deforms under force. When both grinding members 3 contact the inner walls on both sides of the column groove, the support block 2 stops moving. At this time, the adjusting plate 5 continues to move, and the adjusting plate 5 slides outside the rod member 6, and the first spring 7 deforms under force, so that column grooves with different widths can be ground, and the applicable range is wider.

[0035] The limiting mechanism includes an activity groove 31. The activity groove 31 is opened on both sides of the mounting block 30. An elastic member 32 and a limiting block 33 are sequentially arranged inside the activity groove 31 from the inside to the outside. The limiting block 33 is in contact and fit with the protrusion 35, and the upper end end face of the limiting block 33 on the side away from the mounting block 30 is inclined.

[0036] Specifically, the mounting block 30 is inserted into the groove 34. During this process, since the upper end face of the limiting block 33 is inclined, the pressing plate 10 can push the limiting block 33 into the activity groove 31. At this time, the elastic member 32 deforms under force. When the limiting block 33 moves to the corresponding position of the protrusion 35, under the elastic force of the elastic member 32, the elastic member 32 pushes the limiting block 33 out of the activity groove 31, and the limiting block 33 contacts the protrusion 35, so that the mounting block 30 can be fixed to the pressing plate 10.

[0037] The rotating mechanism includes a mounting frame 12 and a shaft member 17. The mounting frame 12 is connected to the support frame 1 through a sliding structure. The shaft member 17 is rotatably inserted into the mounting frame 12 through a driving component. A first gear 23 is fixedly sleeved on the outside of the shaft member 17, a second gear 24 is fixedly sleeved on the outside of the rotating shaft 4, and a toothed belt 25 is jointly sleeved on the outside of the first gear 23 and the two groups of second gears 24.

[0038] The sliding structure includes a sliding rod 13. The sliding rod 13 is fixedly installed on one side of the support frame 1. A fixing block 15 is slidably sleeved on the outside of the sliding rod 13. The fixing block 15 is fixedly connected to the mounting frame 12. A third spring 14 is movably sleeved on the outside of the sliding rod 13. The third spring 14 is fixedly connected to the fixing block 15.

[0039] The driving component includes a cavity 16. The cavity 16 is opened inside the mounting frame 12. The shaft member 17 penetrates the mounting frame 12 and extends into the cavity 16. A plate member 18 is fixedly installed on the outside of the shaft member 17. A feed pipe 19 is fixedly installed on one side below the mounting frame 12. The feed pipe 19 is communicated with the cavity 16. A blower 20 is fixedly installed on the side of the mounting frame 12 away from the feed pipe 19. The air inlet end of the blower 20 is communicated with the cavity 16.

[0040] Further, connect the fan 20 to an external power supply. The fan 20 extracts the air inside the column groove through the feed pipe 19, so that the waste chips inside the column groove can enter the cavity 16 opened in the mounting frame 12 together with the air. When the air passes through the cavity 16, the air contacts the plate member 18 and drives the plate member 18 and the shaft member 17 to rotate, thereby driving the first gear 23 to rotate. A toothed belt 25 is sleeved outside the first gear 23 and the two second gears 24. Therefore, the toothed belt 25 can drive the two second gears 24 to rotate synchronously. The second gear 24 drives the rotating shaft 4 to rotate, providing power for the rotation of the grinding member 3.

[0041] When the two grinding members 3 move away from each other, they drive the rotating shaft 4 to move synchronously. Since the length of the toothed belt 25 is fixed, when the two rotating shafts 4 move away from each other, they can pull the shaft member 17 closer to the support frame 1. During this process, the mounting frame 12 drives the fixed block 15 to slide outside the sliding rod 13, and at this time, the third spring 14 deforms under force.

[0042] A material discharge port 21 is opened below the mounting frame 12. The material discharge port 21 is communicated with the cavity 16. A collection tank 22 is slidably mounted below the mounting frame 12, and the collection tank 22 is located below the material discharge port 21.

[0043] Specifically, when the waste chips enter the cavity 16, under the action of the plate member 18, the plate member 18 drives the waste chips to move inside the cavity 16. When the waste chips move to the position of the material discharge port 21, they can fall into the collection tank 22, thereby collecting the waste chips.

[0044] Working principle: Place the support frame 1 on the surface of the fiberboard, so that the grinding member 3 is inside the column groove. The pressing plate 10 moves downward. The pressing plate 10 drives the two support blocks 2 to move away from each other through the moving mechanism. The support blocks 2 drive the rotating shaft 4 and the grinding member 3 to move synchronously. The two grinding members 3 stop moving after contacting the inner walls on both sides of the column groove respectively. When the mounting block 30 penetrates the groove 34, the limiting mechanism of the mounting block 30 is connected to the protrusion 35. The support block 2 and the pressing plate 10 can be regarded as an integral body. The rotating mechanism drives the grinding member 3 to rotate through the rotating shaft 4 to grind the inner wall of the column groove. Under the action of the driving wheel 29, the frame 26 moves along the surface of the fiberboard. When the column groove is designed in a wavy shape, the frame 26 drives the support frame 1 to move, and the support frame 1 can drive the pressing plate 10 and the slider 27 to move inside the chute 28.

[0045] The pressing plate 10 moves towards the support frame 1, driving the push plate 11 to rotate. The push plate 11 pushes the adjusting plate 5 to move horizontally inside the support frame 1. The two groups of adjusting plates 5 move away from each other. The adjusting plate 5 drives the support block 2 to move synchronously through the rod member 6. At this time, the adjusting plate 5 slides outside the cross bar 8, and the second spring 9 deforms under force. When both grinding members 3 contact the inner walls on both sides of the column groove, the support block 2 stops moving. At this time, the adjusting plate 5 continues to move, and the adjusting plate 5 slides outside the rod member 6, and the first spring 7 deforms under force.

[0046] The mounting block 30 is inserted into the inner part of the groove 34. During this process, since the upper end surface of the limiting block 33 is inclined, the pressing plate 10 can push the limiting block 33 into the inner part of the movable groove 31. At this time, the elastic member 32 deforms under force. When the limiting block 33 moves to the corresponding position of the protrusion 35, under the elastic force of the elastic member 32, the elastic member 32 pushes the limiting block 33 out of the inner part of the movable groove 31. The limiting block 33 contacts the protrusion 35, enabling the mounting block 30 to be fixed to the pressing plate 10.

[0047] Connect the fan 20 to an external power source. The fan 20 extracts the air inside the column groove through the feed pipe 19, so that the waste chips inside the column groove can enter the inner part of the cavity 16 opened in the mounting frame 12 together with the air. When the air passes through the inner part of the cavity 16, the air contacts the plate member 18 and drives the plate member 18 and the shaft member 17 to rotate, thereby being able to drive the first gear 23 to rotate. A toothed belt 25 is sleeved outside the first gear 23 and the two groups of second gears 24. Therefore, the toothed belt 25 can drive the two groups of second gears 24 to rotate synchronously. The second gear 24 drives the rotating shaft 4 to rotate, providing power for the rotation of the grinding member 3.

[0048] When the two groups of grinding members 3 move away from each other, they drive the rotating shaft 4 to move synchronously. Since the length of the toothed belt 25 is fixed, when the two groups of rotating shafts 4 move away from each other, they can pull the shaft member 17 closer to the support frame 1. During this process, the mounting frame 12 drives the fixed block 15 to slide outside the sliding rod 13. At this time, the third spring 14 deforms under force.

[0049] When the waste chips enter the inner part of the cavity 16, under the action of the plate member 18, the plate member 18 drives the waste chips to move inside the cavity 16. When the waste chips move to the position of the discharge opening 21, they can fall into the inner part of the collection tank 22, thereby being able to collect the waste chips.
