[0033] The driving mechanism 5 includes a fixing frame 51, a dual-axis motor 52, a bevel gear 53 and a connecting shaft 54, see Figure 1 and Figure 3 As shown, a fixing frame 51 is installed in the middle of the top right side of the base 1 by welding connection, and a connecting shaft 54 ​​is rotatably connected between the front and rear sides of the bottom of the fixing frame 51 and the top right side of the base 1 respectively, and the upper part of the connecting shaft 54 ​​is connected to the rotating mechanism 6. When the connecting shaft 54 ​​rotates, the connecting shaft 54 ​​can drive the rotating mechanism 6 to operate, and a dual-axis motor 52 is installed in the middle of the bottom of the fixing frame 51. The number of bevel gears 53 is four, of which two bevel gears 53 are installed on the output shaft ends on both sides of the dual-axis motor 52 by welding connection, and the remaining two bevel gears 53 are fixedly mounted on the middle of the front and rear connecting shafts 54 respectively, and the two front bevel gears 53 are meshed with each other, and the two rear bevel gears 53 are meshed with each other.

[0034] The rotating mechanism 6 includes a first transmission assembly 61, a mounting frame 62, a rotating shaft 63 and a second transmission assembly 64. Figure 1 and Figure 4As shown, the front and rear sides of the outer top of the base 1 are both installed with a mounting frame 62 by welding connection. Five rotating shafts 63 are evenly spaced and rotatably connected between the upper and lower sides of the mounting frame 62. The middle part of the rotating shaft 63 is installed with the grinding roller 4 by welding connection. When the rotating shaft 63 rotates, the rotating shaft 63 can drive the grinding roller 4 to rotate. A first transmission component 61 is connected between the bottom end of the rightmost rotating shaft 63 and the top end of the connecting shaft 54. The first transmission component 61 consists of two pulleys and a flat belt. One of the pulleys is fixedly sleeved on the bottom end of the rightmost rotating shaft 63, and the other pulley is fixedly sleeved on the connecting shaft 5 4, the flat belt is wound between the two pulleys, the second transmission assembly 64 is connected between the top of the rightmost rotating shaft 63 and the top of the second rotating shaft 63 from the right and between the top of the second rotating shaft 63 from the left and the top of the third rotating shaft 63 from the left, the second transmission assembly 64 is also connected between the bottom of the second rotating shaft 63 from the right and the bottom of the third rotating shaft 63 from the right and between the bottom of the leftmost rotating shaft 63 and the bottom of the second rotating shaft 63 from the left, the second transmission assembly 64 is composed of two pulleys and a flat belt, the two pulleys are fixedly mounted on the rotating shaft 63, and the flat belt is wound between the two pulleys.

[0035] First, the operator places a wooden board for making a solid wood chair between the two connecting frames 3, the wooden board contacts the grinding roller 4, and then starts the driving mechanism 5. The driving mechanism 5 drives the grinding roller 4 to rotate inward, and the grinding roller 4 moves inward to grind two sides of the wooden board, that is, the burrs on both sides of the wooden board are polished off, and then the connecting frame 3 is pushed to move to the left. The connecting frame 3 moves to the left and drives the loading plate 2 to move to the left. The first spring 22 is stretched, and the connecting frame 3 moves to the left and drives the wooden board to move to the left. The wooden board moves to the left and is better polished. When the wooden board moves to the left and loses contact with the grinding roller 4, the connection frame 3 is stopped and drives the wooden board to move to the left. The connecting frame 3 stops driving the connecting frame 3. The material carrier plate 2 is moved to the left, and the wooden board is rotated 90 degrees by hand so that the other two sides of the wooden board correspond to the grinding roller 4. The wooden board is clamped on the connecting frame 3 with a tool, and the driving mechanism 5 is started to operate to drive the grinding roller 4 to rotate outward through the rotating mechanism 6, and the connecting frame 3 is released. Due to the action of the first spring 22, the material carrier plate 2 moves to the right to drive the connecting frame 3 to move to the right and reset, and the connection frame 3 resets and drives the wooden board to move to the right and reset, and the wooden board moves to the right and is polished by the grinding roller 4, and the grinding roller 4 also polishes the remaining burrs on both sides of the wooden board. After the wooden board is reset, the tool is removed to loosen the wooden board, and then the wooden board is removed. This is repeated to continuously remove the burrs on the four sides of the wooden board. When all the burrs on the four sides of the wooden board are removed, the driving mechanism 5 is turned off, and the driving mechanism 5 stops driving the rotating mechanism 6 to operate, and the rotating mechanism 6 stops driving the grinding roller 4 to rotate.

[0036] When the wooden board is placed between the two connecting frames 3, the double-axis motor 52 is started, and the double-axis motor 52 drives the two lower bevel gears 53 to rotate forward. The positive rotation of the lower two bevel gears 53 drives the upper two bevel gears 53 to rotate inward. The inward rotation of the upper two bevel gears 53 drives the connecting shaft 54 ​​to rotate inward. The inward rotation of the connecting shaft 54 ​​drives the rotation mechanism 6 to operate. The operation of the rotation mechanism 6 drives the grinding roller 4 to rotate inward. The grinding roller 4 rotates inward to remove the burrs on both sides of the wooden board. Then, when the wooden board moves to the left and disengages from the grinding roller 4, the double-axis motor 52 is started to reverse. The double-axis motor 52 reverses and drives the lower bevel gear 53 to reverse. The lower bevel gear 53 reverses and drives the upper bevel gear 53 to rotate outward. The upper bevel gear 53 rotates outward to drive the connecting shaft 54 ​​to rotate outward. The connecting shaft 54 ​​rotates outward and drives the grinding roller 4 to rotate outward through the rotation mechanism 6. When the wooden board moves to the right and resets, the grinding roller 4 rotates outward to remove the burrs on the remaining two sides of the wooden board. When all the burrs on the wooden board are removed, the dual-axis motor 52 is turned off, the dual-axis motor 52 stops driving the lower bevel gear 53 to rotate, the lower bevel gear 53 stops driving the upper bevel gear 53 to rotate, the connecting shaft 54 ​​also stops driving the rotating mechanism 6 to operate, and the rotating mechanism 6 stops driving the grinding roller 4 to rotate.

[0037] When the double-axis motor 52 is started and drives the lower bevel gear 53 to rotate forward, the connecting shaft 54 ​​rotates inwards and drives the first transmission assembly 61 to rotate inwards. The first transmission assembly 61 rotates inwards and drives the rightmost rotating shaft 63 to rotate inwards. The rightmost rotating shaft 63 rotates inwards and drives the innermost grinding roller 4 to rotate inwards. At the same time, the rightmost rotating shaft 63 rotates inwards and drives the remaining rotating shafts 63 to rotate inwards through the second transmission assembly 64. The remaining rotating shafts 63 rotate inwards and drive the remaining grinding rollers 4 to rotate inwards, and then push the connecting frame 3 to drive the wooden board to move to the left and be polished by the grinding roller 4. The grinding roller 4 rotates inwards to remove the burrs on both sides of the wooden board. Then, when the wooden board moves to the left and loses contact with the grinding roller 4, the double-axis motor 52 is started to drive The lower bevel gear 53 is driven to reverse, and the connecting shaft 54 ​​drives the first transmission assembly 61 to rotate outward, and the outward rotation of the first transmission assembly 61 drives the rightmost rotating shaft 63 to rotate outward, and the outward rotation of the rightmost rotating shaft 63 drives the rightmost grinding roller 4 to rotate outward, and the rightmost rotating shaft 63 drives the remaining rotating shafts 63 to rotate outward through the second transmission assembly 64, and the outward rotation of the remaining rotating shafts 63 drives the remaining grinding rollers 4 to rotate outward, and then when the wooden board is clamped by the operator with a tool, the connecting frame 3 is released, the loading plate 2 moves to the right, drives the connecting frame 3 to move to the right and reset, and the connecting frame 3 moves to the right, drives the wooden board to move to the right and reset, and the wooden board contacts the grinding roller 4 again, and the grinding roller 4 rotates outward to remove burrs on the other two sides of the wooden board. When all the burrs on the wooden board are removed, turn off the dual-axis motor 52, the dual-axis motor 52 stops driving the lower bevel gear 53 to rotate, the connecting shaft 54 ​​stops driving the first transmission assembly 61 to rotate, the first transmission assembly 61 stops driving the rightmost rotating shaft 63 to rotate, the rightmost rotating shaft 63 stops driving the rightmost grinding roller 4 to rotate, and the remaining rotating shafts 63 also stop driving the remaining grinding rollers 4 to rotate.

[0038] Example 2

[0039] On the basis of embodiment 1, a clamping mechanism 7 is also included. The clamping mechanism 7 includes a handle 71, a connecting column 72, a mounting frame 73, a guide plate 74, a second spring 75, a limiting plate 76, a magnet 77 and a rotating rod 78. Figure 1 and Figure 5As shown, a rotating rod 78 is rotatably connected to the middle of the loading plate 2, and a mounting frame 73 is installed between the inner ends of the upper parts of the front and rear connecting frames 3 by welding. A guide plate 74 is installed on the top of the mounting frame 73 by welding. A second spring 75 is symmetrically connected to the bottom of the guide plate 74, and a limit plate 76 is fixed between the tail ends of the two second springs 75. The limit plate 76 is located in the mounting frame 73, and a connecting column 72 is fixedly connected to the middle of the limit plate 76 by welding. The top of the connecting column 72 passes through the middle of the guide plate 74 and the top of the mounting frame 73. Magnets 77 are fixed to the bottom of the connecting column 72 and the top of the rotating rod 78. When the wooden board is placed between the two connecting frames 3, the two magnets 77 attract each other to clamp the wooden board. A handle 71 is installed on the top of the connecting column 72 by welding.

[0040] The device further includes a reversing mechanism 8, which includes a groove wheel 81, a rotating rod 82, a trigger rod 83, a ratchet wheel 84, a ratchet bar 85, a clamping block 86 and a third spring 87. Figure 1 , Figure 6 , Figure 7 and Figure 8 As shown, a groove wheel 81 is installed at the lower part of the rotating rod 78 by welding connection along the circumferential direction, a rotating rod 82 is rotatably connected to the middle of the bottom front side of the loading plate 2, a ratchet 84 is fixedly sleeved at the lower part of the rotating rod 82 along the circumferential direction, and four trigger rods 83 are installed at the bottom of the ratchet 84 by welding connection along the circumferential direction. The trigger rod 83 is in contact with the groove wheel 81. When the trigger rod 83 is reversed, the trigger rod 83 can drive the groove wheel 81 to rotate forward. A ratchet strip 85 is slidably connected to the left part of the top front side of the base 1. A return spring is arranged between the ratchet 85 and the base 1. When the ratchet 84 moves to the left and engages with the ratchet 85, the ratchet 85 can drive the ratchet 84 to reverse. Two third springs 87 are connected to the left side of the front side surface of the front mounting frame 62 and the left side of the rear side surface of the rear mounting frame 62. A clamping block 86 is fixedly connected between the tail ends of the two third springs 87 on the front side and between the tail ends of the two third springs 87 on the rear side. When the wooden board moves to the left and contacts with the clamping block 86, the clamping block 86 can limit the wooden board.

[0041] First, the operator pulls the handle 71 upward, and the upward movement of the handle 71 drives the connecting column 72 upward, and the upward movement of the connecting column 72 drives the limit plate 76 upward, the second spring 75 is compressed, and the upward movement of the connecting column 72 also drives the upper magnet 77 upward. When the upper magnet 77 moves upward to a suitable position, the operator stops pulling the handle 71 to drive the connecting column 72 upward, and the connecting column 72 stops driving the upper magnet 77 upward, and then puts the wooden board between the two connecting frames 3, the lower magnet 77 contacts the wooden board, and then releases the handle 71. Hand 71, due to the action of second spring 75, limit plate 76 moves downward to drive connecting column 72 to move downward, connecting column 72 moves downward to drive upper magnet 77 to move downward, upper magnet 77 moves downward to contact with the wooden board, upper and lower magnets 77 attract each other through magnetic force, upper and lower magnets 77 clamp the wooden board, and then the double-axis motor 52 can be started to rotate forward, connecting frame 3 moves leftward to drive mounting frame 73 to move leftward, mounting frame 73 moves leftward through connecting column 72 to drive upper magnet 77 to move leftward, and loading plate 2 moves leftward through rotating rod 78. The lower magnet 77 is driven to move to the left, and the upper and lower magnets 77 are driven to move to the left to drive the wooden board to move to the left and be polished by the polishing roller 4, and then the wooden board moves to the left and is out of contact with the polishing roller 4, the double-axis motor 52 is turned off, the connecting frame 3 stops driving the mounting frame 73 to move to the left, the upper magnet 77 stops moving to the left, and the loading plate 2 stops driving the lower magnet 77 to move to the left through the rotating rod 78, and then the wooden board is pulled to rotate 90 degrees so that the other two sides correspond to the polishing roller 4, the double-axis motor 52 can be started to reverse, and the connecting frame 3 moves to the right to reset, and the upper and lower magnets 77 moves to the right and drives the wooden board to move to the right, and the grinding roller 4 removes the burrs on the other two sides of the wooden board. When the wooden board moves to the right and resets, the dual-axis motor 52 is turned off, and the handle 71 is pulled again to drive the connecting column 72 to move upward, and the connecting column 72 moves upward to drive the upper magnet 77 to move upward, and the upper magnet 77 moves upward and breaks away from the wooden board. Stop pulling the handle 71 to drive the connecting column 72 to move upward, and the connecting column 72 stops driving the upper magnet 77 to move upward, and the wooden board can be removed, and the handle 71 is released to reset, and the upper magnet 77 moves downward to reset. In this way, the movement of the wooden board can be avoided to affect the removal of burrs.

[0042] When the dual-axis motor 52 starts to rotate forward, the loading plate 2 moves to the left and also drives the rotating rod 82 to move to the left. The rotating rod 82 moves to the left and drives the ratchet 84 to move to the left. Then, when the ratchet 84 moves to the left and engages with the ratchet bar 85, the wooden board moves to the left and contacts the clamping block 86. Due to the action of the third spring 87, the clamping block 86 limits the wooden board, and the wooden board is out of contact with the grinding roller 4. The ratchet 84 continues to move to the left and reverses through the ratchet bar 85. The reversal of the ratchet 84 drives the trigger rod 83 to reverse.

A pull wire 97 is wound on the winding wheel 96. The pull wire 97 is made of steel wire. The tail end of the pull wire 97 is fixedly connected to the middle of the left side of the loading plate 2. When the pull wire 97 is wound, the pull wire 97 can drive the loading plate 2 to move to the left. A U-shaped frame 92 is installed on the left side of the top of the base 1 by welding. A driving shaft 93 is rotatably connected between the lower parts of the front and rear sides of the U-shaped frame 92. A second belt assembly 94 is connected between the front side of the driving shaft 93 and the front side of the driven shaft 95. The second belt assembly 94 is composed of two pulleys and a flat belt, one of which is fixedly mounted on the front side of the driven shaft 95, and the other is fixedly mounted on the front side of the driving shaft 93, and the flat belt is wound between the two pulleys. A first belt assembly 91 is connected between the conveying shaft on the front side of the dual-axis motor 52 and the front side of the driving shaft 93. The first belt assembly 91 is composed of two pulleys and a flat belt, one of which is fixedly mounted on the front side of the driving shaft 93, and the other is fixedly mounted on the output shaft on the front side of the dual-axis motor 52, and the flat belt is wound between the two pulleys. When the dual-axis motor 52 is started, the dual-axis motor 52 can drive the first belt assembly 91 to rotate forward.

[0045] The collecting mechanism 10 includes a collecting frame 101, a first magnetic block 102 and a second magnetic block 103. Figure 1 and Fig.11 As shown, the second magnetic block 103 is embedded and fixed on the right part of the front and rear sides of the top of the base 1, and the first magnetic block 102 is placed on the bottom of the second magnetic block 103 through magnetic force. A collection rack 101 is installed between the bottoms of the first magnetic blocks 102 on the front and rear sides. When impurities fall, the collection rack 101 can collect the impurities.

[0046] When the double-axis motor 52 starts to rotate forward, the output shaft on the front side of the double-axis motor 52 also drives the first belt assembly 91 to rotate forward, the first belt assembly 91 rotates forward to drive the driving shaft 93 to rotate forward, the driving shaft 93 rotates forward to drive the second belt assembly 94 to rotate forward, the second belt assembly 94 rotates forward to drive the driven shaft 95 to rotate forward, the driven shaft 95 rotates forward to drive the winding wheel 96 to rotate forward, the winding wheel 96 rotates forward to reel the pull wire 97, and the reeling of the pull wire 97 drives the loading plate 2 to move to the left. Since the material of the pull wire 97 is steel wire, it has better quality and can more stably pull the loading plate 2 to move to the left, which makes the wooden board move to the left and the burrs are polished off by the polishing roller 4, and then the wooden board moves to the left. When the movement is out of contact with the grinding roller 4 and the board rotates forward 90 degrees, the double-axis motor 52 is started to reverse, and the double-axis motor 52 reverses and drives the first belt assembly 91 to reverse through the front output shaft, and the first belt assembly 91 reverses and drives the driving shaft 93 to reverse, and the driving shaft 93 reverses and drives the driven shaft 95 to reverse through the second belt assembly 94, and the driven shaft 95 reverses and drives the winding wheel 96 to reverse, and the pull wire 97 is loosened. Due to the action of the first spring 22, the material carrier 2 moves to the right and drives the connecting frame 3 to move to the right and reset, and the board also moves to the right and resets, and the burrs are polished off by the grinding roller 4, and the material carrier 2 moves to the right and resets and drives the pull wire 97 to move to the right and reset. In this way, the operator does not need to manually pull the connecting frame 3 to drive the board to move to the left, saving time and effort.

[0047] When the grinding roller 4 grinds off the burrs on the wooden board, the impurities generated during the grinding process fall into the collection rack 101. When the collection rack 101 is filled with an appropriate amount of impurities, pull the collection rack 101 downward, and the collection rack 101 moves downward to drive the second magnetic block 103 to move downward. When the second magnetic block 103 moves downward and breaks contact with the first magnetic block 102, the collection rack 101 can be moved to pour out the impurities. After all the impurities are poured out, the collection rack 101 is moved to drive the second magnetic block 103 to move, so that the second magnetic block 103 and the first magnetic block 102 are in contact and attracted to each other, thereby fixing the collection rack 101. In this way, impurities can be prevented from falling around and affecting the environment.
