A guide shaft that slides with the spiral groove is provided on the outer wall of the guide column. A limiting assembly for limiting the rotation of the buffer column is provided inside the base block. After the base block moves down and is fixed by the linkage assembly, the pressure plate presses the surface of the wooden board by the cooperation of the second spring and the pressure rod. Then, the unlocking rod can drive the locking rod to disengage from the locking mouth of the buffer column, so that the buffer column moves up relative to the guide column. The linkage assembly drives the base block to move down by the same stroke, which can also make the pressure plate on the wooden board press the wooden boards of different thicknesses and transport them.

[0021] By setting a recessed groove on the machine base, an anti-feeding plate is provided at the bottom of the driven roller shaft located in the recessed groove. The machine base and the feeding plate are provided with a sliding rod that is slidably connected to the sliding groove at one end.

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Please see Figure 1-12 The present invention provides a technical solution:

[0039] See Figure 1 , 2The planing device for wood surface smoothing disclosed in this embodiment is based on a machine base 1, realizing automatic wood conveying and precise planing. A spiral roller planer 2 is fixedly installed on the top of the machine base 1 for surface smoothing and planing of the wood conveyed below it. A gantry frame 3 is fixedly installed in the middle of the machine base 1, spanning above the machine base 1. Automatic wood board conveying mechanisms 4 are symmetrically installed on both sides of the gantry frame 3. The wood board conveying mechanisms 4 on both sides work together to achieve stable conveying under constant pressure.

[0040] See Figure 2 , 3 4.12. The automatic wood board conveying mechanism 4 includes a base plate 401. To adapt to conveying wood boards of different widths, a T-shaped plate 51 is provided on the top of the base plate 401. A T-shaped groove 52 for sliding the T-shaped plate 51 is provided on the gantry frame 3. A bidirectional lead screw 50 is rotatably provided on the gantry frame 3. The bidirectional lead screw 50 passes through the T-shaped plates 51 on both sides of the automatic wood board conveying mechanism 4 and forms a threaded connection. By rotating the bidirectional lead screw 50, the two sides of the automatic wood board conveying mechanism 4 can be driven to move towards or away from each other. A drive roller 402 and a driven roller 403 are rotatably provided at the bottom of the base plate 401. A motor 405 is provided on the base plate 401 on one side of the drive roller. The output end of the motor 405 is coaxially fixedly connected to the drive roller 402. The drive roller 402 and the driven roller 403 are arranged parallel to each other. A closed transmission belt 404 is sleeved on the outside of the drive roller 402 and the driven roller 403. Multiple sets of wood pressing mechanisms 5 are fixed at even intervals along the circular path. Starting the motor 405 drives the active roller 402 to rotate, which in turn drives the transmission belt 404 and the driven roller 403 to rotate synchronously. The transmission belt 404 can be a toothed transmission belt 404. The active roller 402 and the driven roller 403 can be provided with matching tooth structures on their exteriors to ensure the stability of their cooperation. The transmission belt 404 can also be a chain conveyor belt or other suitable conveyor belts. The automatic wood board conveying mechanism 4 on both sides forms a wood feeding area 53. The bottom of the base plate 401 is located inside the transmission belt 404 and is provided with multiple sets of support rollers 406. The support rollers 406 are arranged and attached to the inner wall of the transmission belt 404 near the wood feeding area 53. During the process of the wood pressing mechanism 5 conveying the wood boards, it is ensured that at least two sets of support rollers 406 support the L-shaped board 501 at any given moment to ensure that the L-shaped board 501 does not sway when conveying the wood boards. It should be noted that the transmission belt 404 and the wood pressing mechanism 5 are all higher than the top of the spiral roller planer 2 to avoid contact with the spiral roller planer 2 during the conveying process.

[0041] See Figure 3 , 45, 6, 9, 10. In the wood pressing mechanism 5, the L-shaped plate is fixed on the transmission belt 404 and moves together with the transmission belt 404. The vertical section of the L-shaped plate 501 has a horizontal sliding groove 7. The sliding rod 5022 of the wood board side pressing head 502 is inserted into the sliding groove 7 and forms a sliding fit. A first spring 6 is also installed in the sliding groove 7. One end of the first spring 6 is fixed to the inner wall of the sliding groove 7, and the other end abuts against the end face of the sliding rod 5022, always applying an outward pushing force to the sliding rod 5022. To prevent the sliding rod 5022 from being ejected from the sliding groove 7 by the force of the first spring 6, a limiting groove 8 is provided on the inner wall of the sliding groove 7, and a limiting block that cooperates with the limiting groove 8 is provided on the outer wall of the sliding rod 5022; L The horizontal section of the template has a vertical through hole for the sliding column 9 at the top of the upper pressure plate 503 to pass through and form a sliding connection. The bottom end of the sliding column 9 is rotatably connected to the upper pressure plate 503 via a bearing, so that when the upper pressure plate 503 presses the wooden board and the wood pressing mechanism 5 has not yet moved to the linear conveying position with the transmission belt 404, the upper pressure plate 503 and the sliding column 9 can rotate relative to each other. The top of the sliding column 9 is fixed with a base plate 10, and the two sides of the bottom of the base plate 10 are symmetrically fixed with limit rods 11. The limit rods 11 pass through the limit holes preset in the horizontal section and form a sliding connection, ensuring that the sliding column 9 can move smoothly up and down on the L-shaped plate 501. The connecting rod assembly 504 is used to connect the wooden board side pressure head 502 and the wooden board upper pressure plate 503. The connecting rod assembly 504 includes a main connecting rod 5041 and an inclined connecting rod 5042. The main connecting rod 5041 consists of a lower main rod 50411 and an upper main rod 50412. The top end of the lower main rod 50411 is fixed with a plug rod 12, which is inserted into the plug rod 12 groove inside the upper main rod 50412 to form a sliding fit. The side wall of the upper main rod 50412 is fixed with a hinge joint 13. The L-shaped plate 501 is provided with a rotation area 14 for the connecting rod to rotate. The rotation area 14 is provided with a hinge hole 15. The hinge joint 13 and the hinge... The connecting hole 15 forms a hinged fit, allowing the main connecting rod 5041 to rotate around the hinge point. The sliding fit between the upper main rod 50412 and the lower main rod 50411 prevents jamming when the slide rod 5022 drives the main connecting rod 5041 to rotate. One end of the main connecting rod 5041 is hinged to the end of the slide rod 5022, and the other end is hinged to one end of the inclined connecting rod 5042. The end of the inclined connecting rod 5042 away from the main connecting rod 5041 is hinged to the height buffer assembly 16, and the entire inclined connecting rod 5042 gradually slopes downward from one end of the main connecting rod 5041 to the top of the upper pressure plate 503 of the wooden board. The pressing block 5021 of the wooden board side pressing head 502 is fixed to the end of the slide rod 5022 away from the first spring 6. The end face of the pressing block 5021 used to press the wooden board is machined into a semi-circular surface to prevent the pressing block 5021 from moving through the transmission belt 404 and causing damage to the edge of the wooden board during the pressing process.

[0042] See Figure 5 , 67, 8. The height buffer assembly 16 is installed on the top of the base plate 10. The height buffer assembly 16 includes a base block 161, a pressure rod 162, a second spring 163, a buffer column 164, a pressure block 165, and a guide column 166. The pressure rod 162 is vertically fixed to the top of the base plate 10. The bottom of the base block 161 is provided with a pressure rod groove 17 that is adapted to the pressure rod 162. The pressure rod 162 is inserted into the pressure rod groove 17 to form a sliding connection. One end of the second spring 163 is fixed to the inner end wall of the pressure rod groove 17, and the other end is fixedly connected to the top end face of the pressure rod 162. This allows the base block 161 to move down and, through the elastic force applied to the pressure rod 162, the pressure plate 503 on the wooden board to press the wooden board tightly. The base block 161 has vertically distributed column grooves 18 and pressure block grooves 19 inside. The column grooves 18 are located at the bottom and the pressure block grooves 19 are located at the top. The buffer column 164 is rotatably assembled in the column groove 18 through a bearing, and the pressure block 165 is slidably disposed in the pressure block groove 19. The guide column 166 is vertically fixed at the bottom end of the pressure block 165. A guide column hole 20 is connected between the column groove 18 and the pressure block groove 19. The guide column 166 passes through the guide column hole 20 and is inserted into the guide column groove 21 opened at the top of the buffer column 164. The inner wall of the guide column groove 21 is machined with a spiral groove 22. A guide shaft 23 is fixed at a corresponding position on the outer wall of the guide column 166. The guide shaft 23 is embedded in the spiral groove 22 to form a sliding fit. The end of the inclined connecting rod 5042 away from the main connecting rod 5041 is hinged to the top of the pressure block 165.The base block 161 also includes a limiting component 24 for restricting the rotation of the buffer column 164. The limiting component 24 includes a locking rod 241, a third spring 242, and an unlocking rod 243. The base block 161 has a locking rod groove 25 communicating with the column groove 18. The locking rod 241 is horizontally slidably disposed in the locking rod groove 25. The outer wall of the buffer column 164 has a plurality of locking holes 26 evenly distributed for the locking rod 241 to be inserted. The third spring 242 is fixed at one end of the locking rod groove 25 away from the column groove 18, and the other end abuts against the end face of the locking rod 241, constantly pushing the locking rod 241 to move towards the column groove 18. The unlocking rod 243 is vertically fixed at the top of the base plate 10. The bottom end of the base block 161 has an unlocking rod 243 groove for the unlocking rod 243 to pass through. The top end of the unlocking rod 243 groove communicates with the locking rod groove 25. The bottom end of the locking rod 241 has a groove, and the side of the groove away from the column groove 18 is machined into... When the unlocking rod 243 moves upward with the base plate 10, its top end can abut against the inclined surface 28 and push the locking rod 241 to retract into the locking rod groove 25, so that the buffer column 164 can rotate. In this way, during the process of the wooden board side pressure head 502 pressing the side of the wooden board, the connecting rod assembly 504 drives the base block 161 to move downward, and the second spring 163 drives the pressure rod 162 to move downward, so that the upper pressure plate 503 of the wooden board presses the wooden board, and then the locking rod 241 disengages from the lock 26. The pressure block 165 can slide downward in the pressure block groove 19 and drive the buffer column 164 to rotate through the cooperation of the guide shaft 23 and the spiral groove 22, so as to achieve the effect of first applying greater pressure to the wooden board and then releasing a certain pressure, ensuring the stable transmission of the wooden board by the automatic wooden board conveying mechanism 4. The height buffer assembly 16 can assist the upper pressure plate 503 of the wooden board in pressing wooden boards of different thicknesses and has a buffer space. It should be noted that, in order to adjust the pressure of the pressure plate 503 pressing the same thickness on the wooden board when the wooden board side pressure head 502 moves the same distance each time, a first adjustment groove is provided on the top of the base plate 10. A first adjustment bolt 29 is rotatably provided in the first adjustment groove. The bottom of the unlocking rod 243 is a cylindrical structure and the top is a square structure. The base plate 10 is provided with a long rod groove 30 in the limiting rod 11 for the bottom of the unlocking rod 243 to pass through and form a sliding connection. The lower end of the unlocking rod 243 passes through the first adjustment bolt 29 and forms a threaded connection with the first adjustment bolt 29. By rotating the first adjustment bolt 29, the height of the unlocking rod 243 in its initial state can be adjusted, thereby controlling the time when the unlocking rod 243 drives the locking rod 241 to disengage from the lock 26. An anti-rotation groove can be provided on the inner wall of the long rod groove 30. An anti-rotation block 31 is provided in the anti-rotation groove of the unlocking rod 243, which can stably control the up and down movement of the unlocking rod 243 when the first adjustment bolt 29 rotates.Additionally, it should be noted that the horizontal movement of the wooden board side pressure head 502 by the same stroke can cause the base block 161 to be pressed down sufficiently by the connecting rod assembly 504, ensuring that the second spring 163 is compressed sufficiently after the upper pressure plate 503 contacts the wooden board, ensuring that the locking rod 241 disengages from the locking port 26 and the second spring 163 returns to a certain amount, so that the upper pressure plate 503 still has sufficient pressure on the top of the wooden board.

[0043] See Figure 3 , 4 11. A feeding plate 32 is slidably provided at one end of the machine base 1 for feeding. A wooden board positioning plate 33 is provided at the end of the feeding plate 32 away from the machine base 1. Side plates 34 are provided on both sides of the feeding plate 32. Guide wheels 35 are rotatably provided inside the side plates 34. Multiple sets of guide wheels 35 are provided along the feeding direction of the wooden board. When the wooden board is pushed between the two sets of automatic wooden board conveying mechanisms 4, the rear end of the wooden board can be attached to the wooden board positioning plate 33. Then, the feeding plate 32 is slid towards the front of the machine base 1 to send the wooden board between the two sets of automatic wooden board conveying mechanisms 4. The guide wheels 35 on both sides can center the wooden board and ensure the pushing position of the wooden board. It should be noted that in order to guide the guide wheels 35 to wooden boards of different widths, a side slide plate 36 is slidably set on the side plate 34. An adjusting screw 37 is threaded to the outside of the side plate 34. One end of the adjusting screw 37 is rotatably connected to the side slide plate 36. The bottom of the side slide plate 36 is fitted with the top of the feeding plate. The position of the side slide plate 36 can be adjusted by rotating the adjusting screw 37. The guide wheels 35 are all rotatably set on the side slide plate 36. To enable the wooden board positioning plate 33 to position wooden boards of different lengths, a first screw 38 is provided at one end of the length of the wooden board positioning plate 33, and a guide rod 39 is provided at the other end of the length of the wooden board positioning plate 33. A first screw 38 is provided at the tail end of the feeding plate for the first screw 38 to slide. A flared opening 41 is provided at the opening of the first screw groove 40. A second adjusting bolt 42 is rotatably provided inside the flared opening 41. The first screw 38 passes through the second adjusting bolt 42 and forms a threaded connection with the second adjusting bolt 42. A guide rod groove 43 is provided on the other side of the feeding plate 32 for the guide rod 39 to slide.

[0044] See Figure 2 , 11The machine base 1 has a recessed groove 44 at the bottom of the driven roller shaft 403. Sliding grooves 45, communicating with the recessed groove 44, are symmetrically arranged on both sides of the front end face of the machine base 1. A sliding rod 46, slidably connected to the sliding groove 45, is provided at the end of the feeding plate 32 near the machine base 1. An adjusting rod 47 is hinged to the end of the sliding rod 46 away from the feeding plate 32. A torsion spring is connected at the hinge point between the adjusting rod 47 and the sliding rod 46. A rotating wheel 48 is provided at the end of the adjusting rod 47 away from the sliding rod 46. The bottom end of the driven roller shaft 403 extends into the recessed groove 44. Multiple sets of anti-feeding plates 49 are evenly arranged on the outer circumference of the driven roller shaft 403 within the recessed groove 44. The adjusting rods 47 on both sides gradually tilt outwards from the sliding rod 46 side towards the driven roller shaft 403 side (in the initial state, the torsion spring causes the adjusting rods 47 to tilt outwards). 7 is tilted outward at a certain angle and cannot continue to rotate outward through the limit. At this time, the adjusting rod 47 can rotate towards the side that is closer to each other after being subjected to force. In this way, when the feeding plate is about to send the wooden board between the two sets of automatic wooden board conveying mechanisms 4, if the adjusting rod 47 abuts against the anti-feeding plate 49, the wooden board will not be able to be sent between the two sets of automatic wooden board conveying mechanisms 4 (at this time, the wooden board is not easy to be stably clamped and conveyed). When the adjusting rod 47 slides without touching the anti-feeding rod, the wooden board can be sent between the two sets of automatic wooden board conveying mechanisms 4 (at this time, the wooden board will be more stably pressed and conveyed by the first set of pressing mechanisms 5 on both sides). When the feeding plate retracts, since the adjusting rod 47 can rotate inward, it will not be interfered with when the feeding plate retracts.

[0045] See Figure 1-12 In this embodiment, when the planing device is working, the distance between the two automatic board conveying mechanisms 4 is first adjusted according to the width of a batch of boards (adjusted by rotating the bidirectional lead screw 50). Then, the guide wheel 35 is positioned to guide the board when the position of the side slide plate 36 is adjusted by rotating the adjusting screw 37. Finally, the position of the board positioning plate 33 is adjusted by rotating the second adjusting bolt 42 according to the length of the board.

[0046] During planing, the wood is placed on the loading plate 32 with the rear end of the board aligned with the board positioning plate 33. The motor 405 is started, driving the drive roller 402 to rotate and the transmission belt 404 to drive the board. All the wood pressing mechanisms 5 move with the transmission belt 404. The loading plate 32 is moved toward the pine wood area, and the sliding rod 46 moves accordingly, driving the roller 48 toward the driven roller 403. When the roller 48 collides with the anti-feed plate 49, the board cannot be fed into the wood feeding area 53. When the roller 48 can enter the gap between the adjacent anti-feed plates 49, the board can be fed into the wood feeding area 53 by the automatic board conveying mechanism 4. Then the loading plate 32 is pulled back. Since the adjusting rod 47 can rotate inward, the loading plate 32 will not be interfered with by the anti-feed plate 49 when it is pulled back.

[0047] Initially, the first set of wood-pressing mechanisms 5 presses the two sides of the wooden board with the side pressing head 502. During the pressing process, the side pressing head 502 moves into the vertical section of the L-shaped plate 501 and drives the main connecting rod 5041 to rotate. Through the inclined connecting rod 5042, the base block 161 moves downward and the pressing rod 162 drives the sliding column 9 to move downward. The downward movement of the sliding column 9 causes the upper pressing plate 503 of the wooden board to press the top of the wooden board. The side pressing head 502 continues to move into the L-shaped plate 501 and after the unlocking rod 243 abuts against the bottom inclined surface 28 of the locking rod 241, the locking rod 241 disengages from the locking slot 26 on the buffer column 164. The guide shaft 23 will move downward relative to the buffer column 164 to create a buffer space and prevent the side pressing head 502 from pressing the wooden board. 02. Due to jamming during the inward sliding of the side wall of the pressed wooden board, the pressing mechanism 5 can also adapt to pressing wooden boards of different thicknesses. Through the cooperation of the buffer column 164, locking rod 241 and unlocking rod 243, the wooden board can be first clamped and fixed and then a certain pressure is released. This ensures that the wooden board is stably transported to the wood feeding area 53 and then pressed and transported under constant pressure, ensuring the planing quality. Then all pressing mechanisms 5 repeat the above-mentioned pressing and feeding actions until the wooden board has completely passed through the spiral roller planer 2 and the surface flat planing operation is completed. The whole process does not require manual pushing and pressing of wood, effectively reducing the operational risk, while ensuring the stability of wood feeding and the planing quality.
