[0034] like Figures 1 to 8 As shown, the present invention provides a wood edge grinding device, comprising a driving device 1 and a wood board body 6, and further comprising;

[0035] A grinding assembly 5, which is mounted on the output end of the driving device 1;

[0036] A protection component 2, which is installed on the outside of the driving device 1 by bolts and sleeved on the outside of the grinding component 5;

[0040] The two rings 53 are both truncated cone-shaped and symmetrically arranged on the grinding knife 51;

[0041] The distance between the two circular rings 53 is adjusted by the support component 3, and then the wood board body 6 is placed between the two support components 3 and the two circular rings 53, the grinding knife 51 contacts the side of the wood board body 6, and the driving device 1 drives the grinding knife 51 to work to process the rough surface of the side of the wood board body 6. The rough surface of the side of the wood board body 6 is polished during the rotation of the grinding knife 51, and the rotation of the grinding knife 51 drives the two circular rings 53 to rotate, and the top and bottom surfaces of the wood board body 6 are contacted through the opposite surfaces of the two circular rings 53, and the cross-section between the two circular rings 53 and the grinding knife 51 forms an angle, and the corners of the wood board body 6 are located within the angle. The burrs at the corners of the wood board body 6 are polished by the rotation of the grinding knife 51 and the second through groove 52, so as to achieve the purpose of polishing the corners of the wood board body 6. At the same time, the burrs at the corners of the wood board body 6 are cut by the cutting through groove 54 to avoid the burrs being too long and increasing the polishing time.

[0042] like Figure 2-Figure 5 As shown, the support assembly 3 includes a fixed rod 31 fixed to the inner wall of the protective assembly 2, the external thread sleeve of the fixed rod 31 is provided with a sleeve 32, the bottom of the sleeve 32 is provided with a rolling ball 33, and the external movable sleeve of the sleeve 32 is provided with a support frame 34.

[0043] There are two support components 3 symmetrically arranged at the top and bottom of the inner wall of the protection component 2;

[0044] The support frame 34 is movably sleeved on the outside of the ring 53;

[0045] The two rolling balls 33 and the opposite surfaces of the two rings 53 remain horizontal.

[0046] The sleeve 32 is rotated according to the thickness of the wood board body 6, and rotates and moves up and down along the outside of the fixing rod 31 under the action of the external thread of the fixing rod 31, thereby shortening the distance between the two balls 33, so that the two balls 33 are in contact with the top and bottom of the wood board body 6. At the same time, since the sleeve 32 and the support frame 34 are movably sleeved, and the support frame 34 is sleeved on the outside of the ring 53, and the two balls 33 and the opposite surfaces of the two rings 53 are kept horizontal, the distance between the two rings 53 is adjusted synchronously during the distance adjustment process between the two balls 33, so that the opposite surfaces of the two balls 33 and the two rings 53 are in contact with the top and bottom of the wood board body 6, and the grinding component 5 is driven by the driving device 1 to grind the wood board body 6, and the driving device 1 is pushed to make the support component 3 move along the wood board body 6 to improve the grinding stability of the driving device 1.

[0047] like Figure 7 and Figure 8As shown, the protection assembly 2 includes a first fixing plate 21 fixedly mounted on the outside of the driving device 1, the first fixing plate 21 is connected to the second fixing plate 28 through a docking rod 27, a slide groove 22 is provided at the top of the first fixing plate 21 and the bottom of the second fixing plate 28, a connecting block 24 is slidably engaged at both ends of the slide groove 22, a movable rod 25 is fixedly mounted at the bottom of the connecting block 24, and a scale 23 is provided at the top of the first fixing plate 21;

[0048] The connecting block 24 is fixed in the slide slot 22 by bolts, and the movable rod 25 moves between the first fixed plate 21 and the second fixed plate 28;

[0049] In the initial state, the rough surface of the wood board body 6 contacts the two movable rods 25 , and the grinding knife 51 is located between the two movable rods 25 .

[0050] By rotating the bolt in the opposite direction to disengage it from the inner wall of the slide groove 22, the connecting block 24 is pushed to slide along the slide groove 22 to drive the movable rod 25 to move. The two movable rods 25 are adjusted according to the thickness of the wood board body 6 to adjust the distance between the midpoint of the two movable rods 25 and the grinding knife 51. Since the two movable rods 25 rotate around the grinding knife 51, they are adjusted to a suitable position according to the ruler 23. The bolt is rotated to contact the inner wall of the slide groove 22 to fix the position of the connecting block 24 and the slide groove 22. At the same time, the position of the movable rod 25 is fixed, and the rough surface of the wood board body 6 is brought into contact with the two movable rods 25. The rough surface of the wood board body 6 can be polished by rotating the grinding knife 51. The thickness of the wood board body 6 can be controlled by adjusting the distance between the midpoint of the two movable rods 25 and the grinding knife 51.

[0051] like Figure 7 As shown, the two movable rods 25 and the docking rod 27 are connected via a bellows 26 , and the bellows 26 is located between the first fixing plate 21 and the second fixing plate 28 .

[0052] The rough surface of the wood board body 6 contacts the two movable rods 25, and the driving device 1 drives the grinding assembly 5 to rotate to grind the rough surface of the wood board body 6. During the grinding process, the corrugated cover 26 protects the generated debris to prevent it from spreading into the air and affecting the surrounding environment.

[0053] like Figure 7 and Figure 8 As shown, the collecting assembly 4 includes a fixing ring 41 fixed to the bottom of the second fixing plate 28 by bolts, the bottom of the fixing ring 41 is connected to a collecting cover 43, the bottom of the grinding knife 51 is equipped with an impeller 42, and the second fixing plate 28 is provided with a first through groove 44.

[0054] The driving device 1 drives the grinding assembly 5 to grind the rough surface of the wood board body 6, and the grinding knife 51 drives the impeller 42 to rotate during rotation. The impeller 42 rotates through the first through slot 44 to extract air from between the first fixing plate 21 and the second fixing plate 28. The grinding knife 51 continuously generates dust during the grinding of the wood board body 6. The dust is sucked through the first through slot 44 and enters the collecting cover 43 for collection. At the same time, the corrugated cover 26 protects the first fixing plate 21 and the second fixing plate 28 during the dust collection process, thereby improving the dust collection effect of the impeller 42 and effectively preventing the dust from spreading into the air and affecting the surrounding environment.

[0055] The rotation of the impeller 42 generates a downward suction force between the first fixed plate 21 and the second fixed plate 28. During this process, the wood chips cut in the second through groove 52 and the cutting through groove 54 are sucked out of the second through groove 52 and the cutting through groove 54, thereby preventing the wood chips from clogging the second through groove 52 and the cutting through groove 54 and improving the grinding effect of the wood board body 6.

[0056] The working principle and use process of the present invention:

[0057] The sleeve 32 is rotated according to the thickness of the wood board body 6, and rotates and moves up and down along the outside of the fixing rod 31 under the action of the external thread of the fixing rod 31, thereby shortening the distance between the two balls 33, so that the two balls 33 are in contact with the top and bottom of the wood board body 6. At the same time, since the sleeve 32 and the support frame 34 are movably sleeved, and the support frame 34 is sleeved on the outside of the ring 53, and the two balls 33 and the opposite surfaces of the two rings 53 are kept horizontal, the distance between the two rings 53 is adjusted synchronously during the distance adjustment process between the two balls 33, so that the opposite surfaces of the two balls 33 and the two rings 53 are in contact with the top and bottom of the wood board body 6;

[0058] By rotating the bolt in the opposite direction to disengage it from the inner wall of the slide groove 22, the connecting block 24 is pushed to slide along the slide groove 22 to drive the movable rod 25 to move, and the two movable rods 25 are adjusted according to the thickness of the wood board body 6 to be polished, so that the distance between the midpoint of the two movable rods 25 and the grinding knife 51 is adjusted. Since the two movable rods 25 rotate around the grinding knife 51, they are adjusted to a suitable position according to the ruler 23, and the bolts are rotated to contact the inner wall of the slide groove 22 to fix the position of the connecting block 24 and the slide groove 22, and at the same time, the position of the movable rod 25 is fixed, so that the rough surface of the wood board body 6 is in contact with the two movable rods 25, and the rough surface of the wood board body 6 can be polished by rotating the grinding knife 51. The thickness of the wood board body 6 can be controlled by adjusting the distance between the midpoint of the two movable rods 25 and the grinding knife 51;

[0059] The distance between the two circular rings 53 is adjusted by the support assembly 3, and then the wood board body 6 is placed between the two support assemblies 3 and the two circular rings 53, the grinding knife 51 contacts the side of the wood board body 6, and the driving device 1 drives the grinding knife 51 to work to process the rough surface of the side of the wood board body 6. The grinding knife 51 grinds the rough surface of the side of the wood board body 6 during rotation, and the rotation of the grinding knife 51 drives the two circular rings 53 to rotate, and the top and bottom surfaces of the wood board body 6 are contacted through the opposite surfaces of the two circular rings 53, and the cross-section between the two circular rings 53 and the grinding knife 51 forms an angle, and the corners of the wood board body 6 are located within the angle, and the burrs at the corners of the wood board body 6 are grinded by the rotation of the grinding knife 51 and the second through slot 52, so that the purpose of grinding the corners of the wood board body 6 can be achieved;

[0060] The driving device 1 drives the grinding assembly 5 to grind the rough surface of the wood board body 6, and the grinding knife 51 drives the impeller 42 to rotate during rotation. The impeller 42 rotates through the first through groove 44 to extract air from between the first fixed plate 21 and the second fixed plate 28. Dust will continue to be generated during the grinding of the wood board body 6 by the grinding knife 51. The dust is sucked through the first through groove 44 and is collected in the collecting cover 43. At the same time, the corrugated cover 26 is used to protect the first fixed plate 21 and the second fixed plate 28 during the dust collection process, thereby improving the dust collection effect of the impeller 42 and effectively preventing the dust from diffusing into the air and affecting the surrounding environment.
