Description

Technical Field

[0001] This invention relates to the field of wood slicing technology, specifically to a slicing device for wood surface smoothing. Background Technology

[0002] Wood surface smoothing slicing equipment is a fundamental piece of equipment in the wood processing industry used for high-precision planing of the upper and lower surfaces of solid wood workpieces and various types of boards. It uses high-speed rotating slicing rollers in conjunction with upper and lower distributed pressure conveying rollers to continuously feed the wood workpiece into the cutting area to remove surface defects such as burrs, ripples, knife marks, and glue residue, resulting in a smooth and flat processed surface.

[0003] However, existing wood surface smoothing and planing equipment still suffers from significant structural defects in lateral positioning and feed assistance. Most commercially available equipment relies on rigid limiting baffles fixed to both sides of the machine or manual support for lateral constraint of the wood workpiece. On the one hand, when the processing distance between the upper and lower planing tables adjusts due to changes in workpiece thickness, the lateral baffles cannot adaptively center themselves, resulting in a height offset between the baffles and the workpiece side, weakening the constraint effect. On the other hand, when planing irregularly shaped wood workpieces with wavy sides or irregular contours, traditional integral flat baffles cannot achieve continuous clamping along the workpiece's length, only contacting the workpiece at a few protruding points. These problems directly lead to the wood workpiece being highly susceptible to horizontal displacement during high-speed planing, resulting in quality defects such as planed surface dimensional deviations, uneven surfaces, edge chipping, and vibration-induced chatter marks. In addition, the workpiece ends are prone to warping and deformation due to insufficient lateral constraints during feeding and discharging. Furthermore, the lack of lateral auxiliary drive during conveying causes slippage, which seriously reduces the yield and processing efficiency, and has become a technical bottleneck restricting the improvement of planing processing quality. Summary of the Invention

[0004] The purpose of this invention is to provide a planing device that can adapt to the unevenness of the wood surface and feed synchronously laterally, preventing workpiece displacement and warping during planing. To achieve the above objective, this invention adopts the following technical solution: A planing device for wood surface smoothing includes a planing machine base, an upper planing table mounted on the planing machine base, multiple conveying rollers arranged in a linear array on each side of the planing machine base and the upper planing table that are close to each other, a planing roller mounted on each side of the planing machine base and the upper planing table that are close to each other, a wood workpiece placed on the planing machine base, and two feed auxiliary components symmetrically arranged on the planing machine base. The feed auxiliary components include... The machine includes a horizontal baffle, which is positioned between the planer table and the upper planer table. Each of the planer table and the upper planer table is equipped with a rack, which is used to adjust the position of the horizontal baffle in the height direction of the planer table, so that no matter how the distance between the planer table and the upper planer table changes, the horizontal baffle is always located in the center position between the planer table and the upper planer table. A scissor mechanism is installed on the side of the horizontal baffle facing the rack, which is used to adjust the position of the horizontal baffle in the width direction of the planer table. A linear module is installed on the side of the scissor mechanism away from the horizontal baffle, which is used to adjust the position of the horizontal baffle in the length direction of the planer table. The horizontal baffle is pressed against the side wall of the wooden workpiece. Multiple side abutments are provided on the side of the horizontal baffle facing the wooden workpiece. The side abutments are made of rubber and have anti-slip texture on their outer surface. The multiple side abutments on the horizontal baffle can be rotated independently to press against the wooden workpiece to adapt to the unevenness of the side of the wooden workpiece. A horizontal pull plate is provided on the horizontal baffle. The horizontal pull plate is used to simultaneously reset all the side abutments, so that the side abutments release the pressing limit on the wooden workpiece.

[0005] Furthermore, the feed auxiliary component also includes two support seats, which are symmetrically and fixedly connected to the planer platform. Each of the two support seats has a guide rod fixedly connected to its top end on the side away from the planer platform. Both guide rods are slidably connected to the linear module. Each of the planer platform and the upper planer table has a support rod fixedly connected to the side near the linear module. Each of the two support rods has a rack I fixedly connected to the end near the linear module. Both rack I are slidably connected to the linear module. A gear I is rotatably connected to the linear module. Each rack I is fitted with a bellows I. A bellows II is fitted on the scissor mechanism.

[0006] Furthermore, the side of the crossbar away from the scissor mechanism has multiple rotating slots arranged in a straight line. Multiple side abutments are rotatably connected to these slots. The crossbar has an upper cavity and a lower cavity. The top and bottom ends of the side abutments at their rotatable connection points with the slots respectively enter the upper and lower cavities. Each side abutment has a ratchet fixedly connected to one end of each side abutment entering the upper cavity. The inner wall of the upper cavity has multiple sliding rods arranged in a straight line, with the number of sliding rods equal to the number of ratchets. Each sliding rod has a sliding seat slidably connected to it. Each sliding rod is fitted with a tension spring, the two ends of which are fixedly connected to the inner wall of the upper cavity and the sliding seat respectively. Each sliding seat has a pawl slidably connected to it. Each sliding seat is equipped with a tension spring II, the two ends of which are fixedly connected to the pawl and the inner wall of the sliding seat, respectively. Each sliding seat has a pull rod fixedly connected to its top, the top of which extends out of the upper cavity. The tops of multiple pull rods are fixedly connected to a horizontal pull plate. Each side abutment rod has a gear II fixedly connected to one end of its insertion into the lower cavity. Each side abutment rod is fitted with two torsion springs, the two ends of which are fixedly connected to the inner wall of the rotating groove and the side abutment rod, respectively. Multiple cylinders are fixedly connected in a linear array in the lower cavity. The number of cylinders is equal to the number of gear IIs. Each cylinder has a rack II fixedly connected to its telescopic shaft end. An air pump is installed on the scissor mechanism, and an air pipe is fixedly connected to the air nozzle of the air pump.

[0007] Furthermore, the two racks are located on both sides of the gear, and both racks mesh with the gear.

[0008] Furthermore, the corrugated pipe is configured as a two-section split type. The ends of the two corrugated pipes that are close to each other are fixedly connected to the straight module, and the ends of the two corrugated pipes that are far apart from each other are fixedly connected to the support rod and the toothed rod, respectively.

[0009] Furthermore, the pawl and ratchet mesh properly.

[0010] Furthermore, rack two and gear two mesh with each other, and the air pipe is fixedly connected to multiple cylinders.

[0011] Furthermore, both ends of the second corrugated pipe are fixedly connected to the scissor mechanism and the cross baffle, respectively.

[0012] Compared with the prior art, the beneficial effects of the present invention are: By automatically centering the horizontal baffle according to the spacing changes of the upper and lower planer tables, it ensures that the lateral clamping force always acts on the middle area of ​​the side of the wood workpiece, regardless of the thickness of the wood workpiece. This avoids uneven force on the upper and lower surfaces of the wood workpiece caused by the offset of the clamping force, thus effectively preventing over-cutting on one side or residual tool marks after planing. It also ensures that the cutting amount on the upper and lower surfaces of the wood workpiece is consistent, resulting in a uniformly flat processed surface.

[0013] By utilizing the pressure self-distribution characteristics of parallel air circuits, multiple independent side abutment rods are driven to rotate and lock differently according to the concave and convex contours of the wood workpiece's sidewall. This ensures that each lateral support point can closely fit the irregular curved surface, significantly enhancing the rigid support of the wood workpiece in the planing area. It effectively suppresses high-frequency vibration of the wood workpiece caused by lateral gaps during high-speed planing, thereby avoiding wavy vibration patterns and uneven defects such as localized chipping and trailing on the planed surface of the wood workpiece.

[0014] Relying on the multi-point, one-way locking function of the bonding and clamping, combined with the same speed auxiliary feed provided by the lateral components, the horizontal posture of the wood workpiece is continuously constrained throughout its entire length. This solves the problem of horizontal movement and warping of the beginning and end of the wood workpiece during the planing process, ensuring the stability of the cutting layer thickness. This results in a smooth and consistent planed surface of the wood workpiece from beginning to end, without any step-like tool marks, and significantly improves the overall surface quality of the wood workpiece.

[0017] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0018] Reference Figures 1 to 12 As shown, a planing device for wood surface smoothing includes a planing machine base 11, an upper planing table 12 installed on the planing machine base 11, multiple conveying rollers 13 installed in a straight array on each side of the planing machine base 11 and the upper planing table 12 that are close to each other, a planing roller 14 installed on each side of the planing machine base 11 and the upper planing table 12 that are close to each other, and a wood workpiece 15 placed on the planing machine base 11. Two feed auxiliary components are symmetrically arranged on the planer table 11. The feed auxiliary components include a horizontal baffle 29, which is located between the planer table 11 and the upper planer table 12. Each of the planer table 11 and the upper planer table 12 is provided with a rack 25. The rack 25 is used to adjust the position of the horizontal baffle 29 in the height direction of the planer table 11, so that no matter how the distance between the planer table 11 and the upper planer table 12 changes, the horizontal baffle 29 is always located in the center position between the planer table 11 and the upper planer table 12. A scissor mechanism 28 is installed on the side of the horizontal baffle 29 facing the rack 25. The scissor mechanism 28 is used to adjust the position of the horizontal baffle 29 in the width direction of the planer table 11. A linear module 23 is installed on the side of the scissor mechanism 28 away from the horizontal baffle 29. The linear module 23 is used to adjust the position of the horizontal baffle 29 in the length direction of the planer table 11. The horizontal baffle 29 is pressed against the side wall of the wooden workpiece 15. Multiple side abutments 214 are provided on the side of the horizontal baffle 29 facing the wooden workpiece 15. The side abutments 214 are made of rubber and have anti-slip texture on their outer surface. The multiple side abutments 214 on the horizontal baffle 29 can be rotated independently to press against the wooden workpiece 15 to adapt to the unevenness of the side of the wooden workpiece 15. A horizontal pull plate 222 is provided on the horizontal baffle 29. The horizontal pull plate 222 is used to synchronously reset all the side abutments 214, so that the side abutments 214 release the pressing and limiting effect on the wooden workpiece 15.

[0019] The feed auxiliary assembly also includes two support seats 21, which are symmetrically fixedly connected to the planer table 11. Each of the two support seats 21 has a guide rod 22 fixedly connected to its top end on the side away from the planer table 11. Both guide rods 22 are slidably connected to the linear module 23. Each of the planer table 11 and the upper planer table 12 has a support rod 24 fixedly connected to the side of the planer table 11 near the linear module 23. Each of the two support rods 24 has a toothed rod 25 fixedly connected to the end of the linear module 23 near the end of the linear module 23. Both toothed rods 25 are slidably connected to the linear module 23. A gear 26 is rotatably connected to the linear module 23. Each of the two toothed rods 25 is fitted with a bellows 27. A bellows 210 is fitted on the scissor mechanism 28. The two ends of the bellows 210 are fixedly connected to the scissor mechanism 28 and the cross plate 29, respectively.

[0020] The side of the horizontal baffle 29 away from the scissor mechanism 28 has multiple rotating slots 211 arranged in a straight array. Multiple side abutment rods 214 are rotatably connected to the multiple rotating slots 211. The horizontal baffle 29 has an upper cavity 212 and a lower cavity 213. The top and bottom ends of the side abutment rods 214 at the rotatable connection positions with the rotating slots 211 respectively pass into the upper cavity 212 and the lower cavity 213. Each side abutment rod 214 is fixedly connected to a ratchet 215 at one end that passes into the upper cavity 212. The upper cavity 212... The inner wall is fixedly connected in a linear array with multiple slide rods 216. The number of slide rods 216 is equal to the number of ratchet wheels 215. Each slide rod 216 is slidably connected to a shift seat 217. Each slide rod 216 is fitted with a tension spring 218. The two ends of the tension spring 218 are fixedly connected to the inner wall of the upper cavity 212 and the shift seat 217, respectively. Each shift seat 217 is slidably connected to a pawl 219. Each shift seat 217 is equipped with a tension spring 220. The two ends of 0 are fixedly connected to the pawl 219 and the inner wall of the shift seat 217, respectively. Each shift seat 217 has a pull rod 221 fixedly connected to its top. The top of the pull rod 221 extends out of the upper cavity 212. The tops of multiple pull rods 221 are fixedly connected to a horizontal pull plate 222. Each side abutment rod 214 has a gear 223 fixedly connected to one end of its insertion into the lower cavity 213. Each side abutment rod 214 is fitted with two torsion springs 224. The two ends of the torsion springs 224 are respectively connected to the rotating... The inner wall of the groove 211 and the side abutment rod 214 are fixedly connected. Multiple cylinders 225 are fixedly connected in a linear array in the lower cavity 213. The number of cylinders 225 and gears 223 is equal. Each cylinder 225 has a rack 226 fixedly connected to its telescopic shaft end. The rack 226 and gears 223 mesh with each other. An air pump 227 is installed on the scissor mechanism 28. An air pipe 228 is fixedly connected to the air nozzle of the air pump 227. The air pipe 228 is fixedly connected to multiple cylinders 225.

[0021] Wherein: conveying roller 13 and slicing roller 14 are both existing known technologies. Conveying roller 13 is used to move the wood workpiece 15 by rolling, and slicing roller 14 is used to slice the wood workpiece 15.

[0022] Among them, the two racks 25 are located on both sides of the gear 26, and both racks 25 mesh with the gear 26.

[0023] Among them, the corrugated pipe 27 is set as a two-section split type. The ends of the two corrugated pipe 27 that are close to each other are fixedly connected to the linear module 23, and the ends of the two corrugated pipe 27 that are far apart from each other are fixedly connected to the support rod 24 and the toothed rod 25 respectively.

[0024] Among them, the scissor mechanism 28 is a known existing technology. The scissor mechanism 28 consists of two sets of equal-length rods that are hinged together to form an X shape. By adjusting the included angle of the two sets of rods, the scissor mechanism 28 can push the horizontal baffle 29 to move horizontally.

[0025] The function of corrugated pipe 1 27 and corrugated pipe 2 210 is to provide shielding and protection for the internal structure, and to prevent wood chips generated during the planing process of the wood workpiece 15 from entering the interior and interfering with its operation.

[0026] Among them, the pawl 219 and the ratchet 215 are properly meshed.

[0027] The ratchet 215, pawl 219, and tension spring 220 work together to form a unidirectional limiting rotation mechanism in the prior art. The ratchet 215 has unidirectional teeth on its outer circumference, and the pawl 219 always abuts against the tooth surface of the ratchet 215 by the tension spring 220. When the ratchet 215 rotates in the forward direction, the tooth surface slides away the pawl 219, allowing it to rotate freely. When it rotates in the reverse direction, the pawl 219 engages with the tooth groove, pressing against the tooth surface to prevent the ratchet 215 from rotating back, thereby achieving unidirectional rotation and reverse limiting locking.

[0028] It should be noted that, compared with the prior art, in addition to the movement direction of the pawl 219 elastically engaging with the ratchet 215, the pawl 219 also obtains the vertical movement freedom through the sliding engagement of the shift seat 217 on the slide bar 216. When the shift seat 217 drives the pawl 219 to move upward, the pawl 219 and the ratchet 215 are vertically misaligned, thereby releasing the rotation limit on the ratchet 215.

[0029] The function of the air pump 227 located on the scissor mechanism 28 is that the air pump 227 is located outside the working surface of the planer table 11 and the upper planer table 12, so as to avoid the air pump 227 interfering with the planing process of the wood workpiece 15.

[0030] It should be added that the height of the horizontal baffle 29 is adapted to the thickness of the conventional wood workpiece 15. Specifically, when processing the conventional thickness wood workpiece 15, the horizontal baffle 29 is always positioned between the planer table 11 and the upper planer table 12, and there are gaps between the horizontal baffle 29 and both the planer table 11 and the upper planer table 12. This avoids the horizontal baffle 29 interfering with the processing of the wood workpiece 15, and also avoids the horizontal baffle 29 interfering with the adjustment of the processing gap between the planer table 11 and the upper planer table 12.

[0031] In the initial state, that is, before the planing operation of the wood workpiece 15 has been performed, the structural states of each component in the feed auxiliary assembly are as follows: The upper planer 12 is adjusted to the state with the farthest distance between it and the planer table 11. The conveyor roller 13 and the planer roller 14 are not started. The scissor mechanism 28 is located on the feed side of the planer table 11 on the linear module 23. The output end of the scissor mechanism 28 is fully retracted. The horizontal baffle 29 is located at the edge position of the planer table 11 and the upper planer 12. The two horizontal baffles 29 are at the farthest distance between each other. The side abutment rod 214 has not rotated outward from the rotating groove 211. The torsion spring 224 has not yet produced elastic deformation. The tension spring 1 218 and tension spring 220 have not produced elastic deformation. The pawl 219 is engaged with the ratchet 215. The shift seat 217 is in contact with the bottom of the inner wall of the upper cavity 212. The horizontal pull plate 222 is in contact with the top of the horizontal baffle 29. The telescopic shaft of the cylinder 225 has not yet extended. The air pump 227 has not yet started.

[0032] When planing of the wood workpiece 15 is required, the feed auxiliary component operates as follows: The user places the wood workpiece 15 on the feed side of the planing machine table 11, so that the wood workpiece 15 is positioned between the planing machine table 11 and the upper planing table 12, and the wood workpiece 15 overlaps with the conveyor roller 13 near the feed side of the planing machine table 11. Then, the user adjusts the processing distance between the planing machine table 11 and the upper planing table 12 according to the thickness of the wood workpiece 15 being processed, causing the upper planing table 12 to move downwards and close towards the planing machine table 11. During the downward movement of the upper planing table 12, the upper planing table 12 drives the corresponding toothed rod through the support rod 24. 25 moves down synchronously. During the downward movement of rack 25, rack 25 meshes with gear 26 to rotate, thereby pushing rack 25, which is connected to the planing table 11, to tend to move upward. However, since the position of planing table 11 is fixed, the axis of gear 26 can only take the compromise position between the displacement of the upper planing table 12 and the planing table 11, thereby achieving synchronous constraint on both sides of gear 26, forcing gear 26 to automatically follow the movement of the upper planing table 12, and always stay in the center position between the planing table 11 and the upper planing table 12.

[0033] As gear 26 moves downwards with the upper planer table 12 to adjust its position, gear 26 drives the linear module 23 to adjust its position synchronously. At this time, the linear module 23 slides on the guide rod 22, and the linear module 23 drives the horizontal baffle 29 to always be in the center position between the planer table 11 and the upper planer table 12. That is, no matter how the upper planer table 12 adjusts the distance between itself and the planer table 11, the horizontal baffle 29 will always be in the center position between the planer table 11 and the upper planer table 12. Furthermore, after the upper planer table 12 is adjusted, the distance between the planer table 11 and the upper planer table 12 is adapted to the wood workpiece 15. At this time, the two horizontal baffles 29 are located in the middle position on both sides of the wood workpiece 15. The upper planer table 12 is pressed against the upper surface of the wood workpiece 15 by the conveyor roller 13, and the lower surface of the wood workpiece 15 is pressed against by the planer table 11 by the conveyor roller 13.

[0034] The user then drives the two scissor lift mechanisms 28 to operate. The output end of the scissor lift mechanism 28 pushes the horizontal baffle 29 to move, so that the two horizontal baffles 29 move synchronously towards the wood workpiece 15 until the horizontal baffles 29 abut and press against the side wall of the wood workpiece 15. At this time, the user drives the air pump 227 to operate. The air pump 227 sprays air into the air pipe 228. The air flow in the air pipe 228 enters each cylinder 225. As the gas fills the cylinder 225, the gas pushes the telescopic shaft of the cylinder 225 to extend. Thus, the telescopic shaft end of the cylinder 225 pushes the rack 226 to move towards the gear 223. During the movement, the rack 226 meshes with the gear 223 and rotates. During the rotation of the gear 223, the gear 223 synchronously drives the side abutment rod 214 to rotate, so that the side abutment rod 214 rotates in the rotating groove 211 towards the wood workpiece 15.

[0035] Since the horizontal baffle 29 is already in contact with and pressed against the side wall of the wooden workpiece 15, the wooden workpiece 15 is located on the rotation trajectory of the side abutment rod 214. That is, as the side abutment rod 214 rotates, it will contact and press against the side wall of the wooden workpiece 15. If the wooden workpiece 15 is irregularly shaped, that is, the side of the wooden workpiece 15 has a concave and convex shape, and the position and shape of each side abutment rod 214 corresponding to the wooden workpiece 15 are different, that is, the rotation angle required for each side abutment rod 214 to contact the wooden workpiece 15 is different. Similarly, the amount of air in the cylinder 225 corresponding to each side abutment rod 214 is different.

[0036] When the side abutment rod 214 rotates to contact the wooden workpiece 15, it is restricted from further rotation by the wooden workpiece 15. The telescopic shaft of the cylinder 225 at this position cannot extend further. However, since all cylinders 225 are connected through the air pipe 228, the gas will flow into the cylinder 225 corresponding to the side abutment rod 214 that has not yet contacted the wooden workpiece 15, and maintain the gas-filled state inside the cylinder 225 that can no longer extend. That is, by the simultaneous flow of gas in multiple cylinders 225, the independent rotation of multiple side abutment rods 214 can be achieved. The rotation angle of each side abutment rod 214 is determined according to the concave and convex shape of the corresponding position of the wooden workpiece 15. That is, the rotation angle of each side abutment rod 214 is different, ensuring that each side abutment rod 214 can rotate to contact the wooden workpiece 15.

[0037] When the side abutment rod 214 rotates to press against the wooden workpiece 15, the rubber material of the side abutment rod 214 is pressed against the wooden workpiece 15, thereby generating elastic deformation, so that the side abutment rod 214 can fit tightly against the wooden workpiece 15 and adapt to the complex shape of the side wall of the wooden workpiece 15. The side abutment rod 214 enhances the friction between itself and the wooden workpiece 15 through anti-slip texture, thereby enhancing the clamping force of the two horizontal baffles 29 on the wooden workpiece 15.

[0038] Furthermore, during the rotation of the side abutment rod 214, the side abutment rod 214 drives the ratchet 215 to rotate synchronously. The tooth surface of the ratchet 215 slides away the pawl 219, causing the tension spring 220 to undergo elastic deformation. Under the elastic restoring action of the tension spring 220, the pawl 219 can always be in contact with the ratchet 215, allowing the ratchet 215 to rotate freely. However, the pawl 219 restricts the reverse rotation of the ratchet 215. That is, after the side abutment rod 214 rotates to be in contact with and pressed against the wood workpiece 15, the side abutment rod 214 cannot rotate in the reverse direction, thereby fixing the state of the side abutment rod 214 limiting the wood workpiece 15. At this time, the wood workpiece 15 is limited at the top and bottom by the planing machine table 11 and the upper planing table 12, and limited on both sides by the horizontal baffle 29 through the side abutment rod 214, thereby effectively preventing the wood workpiece 15 from shifting during the planing process.

[0039] It should be noted that since the side abutment rods 214 on a single horizontal baffle 29 are arranged at multiple points, they form multiple points of limiting on both sides of the wood workpiece 15. In addition to applying a horizontal inward pushing force to both sides of the wood workpiece 15, the multiple points of limiting can also prevent the wood workpiece 15 from warping at both ends, thereby avoiding the situation where the ends of the wood workpiece 15 lose restraint and warp during feeding and discharging.

[0040] At this point, the clamping of the wood workpiece 15 is completed. The user can drive the conveyor roller 13 and the slicing roller 14 to run. The conveyor roller 13 rotates and causes the wood workpiece 15 to move on the slicing machine table 11. At the same time, the user drives the linear module 23 to run, so that the actuator of the linear module 23 drives the cross baffle 29 to move on the slicing machine table 11. It should be noted that the moving speed of the cross baffle 29 is consistent with the moving speed of the wood workpiece 15. The linear module 23 is used to provide the same speed drive as the top and bottom sides of the wood workpiece 15 on the side, ensuring that the wood workpiece 15 is in a state of synchronous movement, and further stabilizing the slicing posture of the wood workpiece 15.

[0041] As the wood workpiece 15 moves on the planer table 11 and the upper planer table 12, the two planing rollers 14 simultaneously plan the upper and lower sides of the wood workpiece 15, so that the surface of the wood workpiece 15 passing through the position of the planing rollers 14 is planed flat. During the planing process, the two sides of the wood workpiece 15 are always constrained by the horizontal baffle 29 through the side abutment rod 214, thereby preventing the wood workpiece 15 from deviating or shifting.

[0042] After the wood workpiece 15 is planed, it moves to the discharge side on the planer table 11. At this point, the wood workpiece 15 is removed from the bottom of the upper planer table 12. The user needs to unload the wood workpiece 15. The user then drives both scissor mechanisms 28 to retract simultaneously, causing the two horizontal baffles 29 to move away from each other and no longer compress the wood workpiece 15. Thus, the wood workpiece 15 is no longer restricted, and the user can directly remove it. After the horizontal baffles 29 are reset by the scissor mechanisms 28, the user pulls the horizontal pull plate 222 upwards, simultaneously driving the air pump 227 to evacuate air from the air pipe 228. As the horizontal pull plate 222 is pulled upwards, the horizontal pull plate 222... The pull rod 221 drives all the shift seats 217 to move upward synchronously, causing the shift seats 217 to slide upward on the slide rod 216. At the same time, the tension spring 218 undergoes elastic deformation, and the shift seats 217 simultaneously drive the pawl 219 to move upward, causing the pawl 219 to move upward until it is misaligned with the ratchet 215. Thus, the pawl 219 no longer restricts the reverse rotation of the ratchet 215. At this time, under the elastic reset action of the torsion spring 224, the torsion spring 224 drives the side abutment rod 214 to rotate and reset in the rotating groove 211. At the same time, the side abutment rod 214, through the cooperation of the gear 223 and the rack 226, and under the suction action of the air pump 227, causes the gas in the cylinder 225 to be discharged, and the telescopic shaft of the cylinder 225 to retract. After completion, the user moves the horizontal baffle 29 to the feeding side of the planer table 11 through the linear module 23. At this time, all structures of the feeding auxiliary components have completed their reset.

[0043] In summary, the following beneficial effects can be achieved through the design of the feed auxiliary components: By automatically centering the horizontal baffle 29 according to the spacing changes of the upper and lower planer tables, it is ensured that the lateral clamping force always acts on the middle area of ​​the side of the wood workpiece 15, regardless of the thickness of the wood workpiece 15. This avoids uneven force on the upper and lower surfaces of the wood workpiece 15 due to the offset of the clamping force, thereby effectively preventing overcutting on one side or residual tool marks after planing, and ensuring that the cutting amount on the upper and lower surfaces of the wood workpiece 15 is consistent, resulting in a uniformly flat processing surface.

[0044] By utilizing the pressure self-distribution characteristics of the parallel air circuit, multiple independent side abutment rods 214 are driven to rotate and lock differently according to the concave and convex contours of the side wall of the wood workpiece 15, so that each lateral support point can closely fit the irregular curved surface, which significantly enhances the rigid support of the wood workpiece 15 in the planing area and effectively suppresses the high-frequency vibration of the wood workpiece 15 caused by lateral gaps during high-speed planing, thereby avoiding wavy vibration patterns and uneven defects such as local chipping and trailing on the planed surface of the wood workpiece 15.

[0045] Relying on the multi-point, one-way locking function of the mating and clamping, combined with the same speed auxiliary feed provided by the lateral components, the horizontal posture of the wood workpiece 15 is continuously constrained throughout its entire length. This solves the problem of horizontal movement and warping of the beginning and end of the wood workpiece 15 during the planing process, ensuring the stability of the cutting layer thickness. As a result, the planed surface of the wood workpiece 15 is smooth and consistent from beginning to end, without any step-like tool marks, which significantly improves the overall surface quality of the wood workpiece 15.
