Description

Technical Field

[0001] The present invention relates to the field of solid wood board grinding, and specifically to a surface grinding device and a usage method for solid wood boards used in customized furniture. Background Technique

[0002] During the production of customized furniture, operations such as cutting, surface grinding, and painting of solid wood boards are usually required. When grinding the surface of solid wood boards, special grinding devices are usually used for processing.

[0003] A prior patent (Publication No.: CN114274011A) discloses a wood board grinding device, including a frame and a feeding frame and a grinding frame located above the frame. Among them, a feeding mechanism and a turning mechanism are provided in the feeding frame. The inventor found the following problems in the prior art that have not been well solved during the implementation of this solution: 1. When this device grinds solid wood boards, it can only grind one side of the board through the abrasive rollers inside the grinding frame, and the grinding efficiency is low; 2. Usually, when the surface of the board is being ground, the conveyor transports the board towards the grinding rollers, and when the board passes through the grinding rollers, the grinding is completed. At this time, the board is only ground once on the surface by the grinding rollers. Since there are protrusions on the surface of some boards, it is difficult to effectively grind the protrusion positions with a single grinding. In the above-mentioned comparative document, the second linear motor drives the abrasive rollers to slide in the grinding frame to complete the grinding of the side of the board, and this grinding method also has this technical problem, affecting the grinding quality. Summary of the Invention

The rotating end of the micro transmission motor is fixedly connected to the bottom of the adjacent transmission roller.

[0024] Preferably, the grinding mechanism includes grooves. There are four grooves, and every two grooves are set as a group. The two groups of grooves are symmetrically formed on both sides of the top of the wooden board support. An adjusting telescopic rod is arranged on the inner wall of the groove. One end of the adjusting telescopic rod is fixedly connected to the inner wall of the adjacent support frame. An L-shaped mounting plate is fixedly connected between one ends of two adjusting telescopic rods at the same level. A sandpaper is fixedly connected to the side wall of the mounting plate.

[0025] Preferably, the top surface of the L-shaped mounting plate is an inclined surface, and the distance between the left end of the L-shaped mounting plate and the inner wall of the wooden board support is the same as the length of the groove.

[0026] A using method of a surface grinding device for solid wood boards used in customized furniture includes the following steps:

[0027] S1. When using this solid wood board grinding device, first place the solid wood board on the top surfaces of the two wood board cushion strips inside the wood board support frame. Then rotate the locking screw to press against the solid wood board and move it, so that the solid wood board is clamped between the main gasket and the secondary gasket. Then insert the guide wheel rods on both sides of the support frame into the guide grooves on the two support frames respectively, so that the bottom of the support frame is lapped on the top surface of the left conveyor. At this time, the bottom of the spring telescopic rod is pressed by the top surface of the conveyor and contracts. Then start the conveyor and the drive motor, so that the conveyor conveys the support frame to the right. At the same time, the two grinding rollers start to rotate counterclockwise;

[0028] S2. When the grinding rollers rotate, the main gears on the surfaces of the grinding rollers mesh with the secondary gears on the side walls of the support frames, so that the secondary gears drive the drive rods and the half gears to rotate synchronously. When the support frame drives the wood board support frame and the wood board to move to the position of the grinding rollers, the grinding hairs on the surfaces of the grinding rollers contact the surface of the wood board for grinding. At this time, the half gear rotates clockwise and meshes with the top surface of the adjustment rack, so that the adjustment rack drives the wood board support frame to move towards the left side of the inner wall of the support frame through the adjustment rod. When the half gear disengages from the adjustment rack, the return spring drives the wood board support frame to move to the right and reset. In this way, the wood board support frame drives the wood board to move back and forth slowly in the process of moving forward at the bottom of the grinding rollers, and can grind the surface of the wood board multiple times;

[0029] S3. When the wood board support frame moves back and forth inside the support frame, the adjustment telescopic rods and the L-shaped mounting plates fixedly connected to the inner wall of the support frame are misaligned relative to the position of the solid wood board on the wood board support frame, so that the sandpaper grinds the two sides of the solid wood board synchronously;

[0030] S4. When the top surface of the solid wood board is ground by the left grinding roller, the support frame moves to the middle position between the two support frames. At this time, the spring telescopic rod is released from the pressed state and extends. Then start the micro conveyor motor to drive the conveyor belt to rotate, so that the teeth on the side wall of the conveyor belt contact the side wall of the guide wheel rod. At this time, the two conveyor belts drive the two guide wheel rods and the support frame to move to the right. When the spring telescopic rod moves to the corresponding adjustment plate position, the side wall of the lower part of the spring telescopic rod moves along the side wall track of the adjustment plate, so that the spring telescopic rod pulls the wood board cushion strip into the inside of the movable groove. The wood board cushion strip releases the support of the solid wood board. As the support frame continues to move to the right, at this time, the pressing rod on the side wall of the wood board support frame moves to the position of the convex block, so that one end of the pressing rod is pressed to drive the transmission rack to translate inside the transmission groove. At this time, the gear rod on the top surface of the transmission rack meshes, so that the gear rod drives the secondary gasket, the wood board and the main gasket to rotate 180 degrees inside the wood board support frame to turn over the solid wood board;

[0031] S5. When the support frame moves to the top surface of the right conveyor, the spring telescopic rod is released from contact with the adjustment plate. At this time, the compression spring presses the wood board cushion strip to extend out of the movable groove and lap on the surface of the solid wood board. Then the right grinding roller grinds the surface of the turned-over solid wood board.

[0032] Advantages of the present invention compared with the prior art:

[0033] In the present invention, through the combined use of components such as a commutation mechanism, a grinding mechanism, and grinding rollers, the wooden board is clamped inside the wooden board bracket. When the wooden board passes through the position of the left grinding roller, the top surface of the wooden board is ground. When the wooden board moves to the middle position of the support frame, the commutation mechanism is used to change the surface. When the wooden board moves to the position of the right grinding roller, the ground surface of the wooden board can be ground. At the same time, during the movement of the wooden board, the grinding mechanism synchronously grinds both sides of the wooden board, realizing a flow operation and synchronous multi-surface grinding, improving the grinding processing efficiency.

[0034] In the present invention, through the combined use of components such as an adjustment mechanism, grinding rollers, and a support frame, when the support frame moves the wooden board bracket to the bottom of the grinding roller, under the action of the adjustment mechanism, the wooden board bracket drives the solid wooden board to reciprocate inside the support frame, enabling the grinding roller to grind the top surface of the solid wooden board multiple times, avoiding the difficulty of leveling the convex positions on the surface of the wooden board at one time, and improving the grinding quality.

[0035] In the present invention, through the combined use of components such as a locking screw, a wooden board bracket, and wooden board cushion strips, the solid wooden board is placed on the top surfaces of the two wooden board cushion strips inside the wooden board bracket, and then the wooden board can be positioned by rotating the locking screw, which is convenient for installing the wooden board and improving the stability during the grinding and surface-changing processes of the wooden board.

Specific implementation manners

[0049] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

[0050] Please refer to Figures 1 to 12The present invention provides a technical solution: a solid wood board surface polishing device for custom furniture, comprising a support frame 1, wherein the support frames 1 are provided in two, and a conveyor 2 is symmetrically and movably connected between opposite sides of the two support frames 1. It should be noted that the conveyor 2 is a prior art and will not be described in detail, and a vacuum cleaner can be provided on the side wall of the support frame 1 to facilitate the extraction of dust generated during the polishing process, and a dust box is provided on the bottom surface of the middle part of the two support frames 1 to facilitate the collection of dust.

[0051] The side wall of the support frame 1 is provided with a guide groove 3, and a guide wheel rod 4 is slidably connected inside the guide groove 3, a support frame 5 is fixedly connected between the two guide wheel rods 4, and a wooden board bracket 6 is movably connected inside the support frame 5. It should be noted that: the right side of the wooden board bracket 6 is overlapped with the right side of the inner wall of the support frame 5, the wooden board bracket 6 is set in a return shape, and is set through from top to bottom, and the top surface of the wooden board bracket 6 is set flush with the top surface of the support frame 5; the left end of the guide groove 3 is set as a conical surface, which facilitates the guide wheel rod 4 to be inserted into the inside of the guide groove 3, and a tooth groove is provided along the circumference of one side of the guide wheel rod 4 located in the guide groove 3.

[0052] A grinding roller 7 is symmetrically rotatably connected between the tops of the two support frames 1, and an adjustment mechanism 8 is movably connected between the two sides of the grinding roller 7 and the two sides of the support frame 5. One side of the adjustment mechanism 8 is fixedly connected to the surface of the wooden board bracket 6, and the side wall of the adjustment mechanism 8 is movably connected to the side wall of the support frame 1.

[0053] A reversing mechanism 9 is movably connected between the interior of the wooden board support 6 and the middle of the two support frames 1. One end of the reversing mechanism 9 is movably connected to the surface of the support frame 5. A polishing mechanism 10 is movably connected between the inner wall of the support frame 5 and the top surface of the wooden board support 6.

[0054] The side wall of the rear support frame 1 is fixedly connected with a trapezoidal pad 11, and the top of the trapezoidal pad 11 is fixedly connected with a transmission motor 12. The rotating end of the transmission motor 12 is fixedly connected to one end of the left grinding roller 7, and a synchronous belt 13 is movably connected between the two grinding rollers 7. It should be noted that the synchronous belt 13 is set to make the grinding rollers 7 turn in the same direction to achieve synchronous grinding, so that when the left grinding roller 7 is grinding the top surface of the solid wood board for custom furniture, the right grinding roller 7 can grind the bottom surface of another solid wood board, so as to achieve flow-type processing and improve processing efficiency.

[0055] In this embodiment, Figures 1 to 12 As shown, the adjustment mechanism 8 includes an adjustment slot 801, and there are four adjustment slots 801, which are symmetrically arranged on the front and rear sides of the support frame 5. An adjustment rod 802 is slidably connected inside the adjustment slot 801, and one end of the adjustment rod 802 is fixedly connected to the side wall of the wooden board support 6. An adjustment rack 803 is fixedly connected between two adjustment rods 802 at the same level. It should be noted that the two adjustment slots 801 at the same level are symmetrically arranged.

[0056] On the left side of the wooden board support 6, a sliding rod 804 is symmetrically and fixedly connected. One end of the sliding rod 804 penetrates through the support frame 5 and is fixedly connected with a retaining ring 805. A return spring 806 is movably sleeved on the surface of the sliding rod 804. It should be noted that: the return spring 806 is provided to reset the wooden board support 6 after it moves to the left.

[0057] On both sides of the grinding roller 7, main gears 807 are fixedly sleeved. On the side walls of the two support frames 1, transmission rods 808 are rotatably connected. The two transmission rods 808 correspond to the two main gears 807 one by one. On the surface of the transmission rod 808, a driven gear 809 is fixedly sleeved. The top of the driven gear 809 meshes with the bottom of the adjacent main gear 807. On the side of the transmission rod 808 away from the support frame 1, a half gear 810 that cooperates with the adjusting rack 803 is fixedly sleeved. The two half gears 810 correspond to the two adjusting racks 803 one by one. It should be noted that: when the support frame 5 drives the adjusting rack 803 to move to the position of the half gear 810, the rotating half gear 810 meshes with the adjusting rack 803 periodically.

[0058] In this embodiment, as Figures 1 to 12 shown, the distance between the left side of the inner wall of the support frame 5 and the left side of the wooden board support 6 is set to 1.2 times the length of the adjusting groove 801. It should be noted that: when the half gear 810 meshes with the adjusting rack 803, the adjusting rack 803 drives the adjusting rod 802 to move from one side of the adjusting groove 801 to the other side. At this time, the left side of the wooden board support 6 does not contact the left side of the inner wall of the support frame 5, avoiding interference.

[0059] The length of the adjusting rack 803 is set to 1.2 times the length of the side wall of the support frame 5. It should be noted that: the distance for the adjusting rack 803 to mesh with the half gear 810 is greater than the length of the solid wood board inside the wooden board support 6. When the top surface of the solid wood board passes through the bottom position of the grinding roller 7, the effect of the reciprocating movement of the wooden board support 6 can be stably maintained, improving the grinding effect.

[0060] In this embodiment, as Figures 1 to 12 shown, the reversing mechanism 9 includes movable grooves 901. There are two movable grooves 901, which are symmetrically opened on the front and rear sides of the inner wall of the wooden board support 6. Inside the movable groove 901, a wooden board cushion strip 902 is slidably connected. Between the side wall of the wooden board cushion strip 902 and the inner wall of the adjacent movable groove 901, a compression spring 903 is fixedly connected.

[0061] A spring telescopic rod 904 is fixedly connected to the bottom of the wooden board spacer 902, and an installation groove 905 matching the spring telescopic rod 904 is opened on the inner bottom surface of the movable groove 901. It should be noted that: after the spring telescopic rod 904 contracts, the bottom of the spring telescopic rod 904 is flush with the bottom surface of the wooden board support 6, and the bottom surface of the wooden board support 6 is flush with the bottom surface of the support frame 5. When the support frame 5 is lapped on the top of the conveyor 2 and conveyed to the right, it avoids the interference of the spring telescopic rod 904 on the movement of the support frame 5.

[0062] A locking screw rod 906 is movably connected to the right side of the support frame 5. The middle of the locking screw rod 906 is screw-connected to the right side of the wooden board support 6. The left end of the locking screw rod 906 penetrates through the wooden board support 6 and is rotatably connected with a main gasket 907. It should be noted that: a through groove matching the locking screw rod 906 is opened on the right side of the support frame 5. A support bearing is fixedly connected between the main gasket 907 and the locking screw rod 906 to avoid the rotation of the main gasket 907 driving the locking screw rod 906 to rotate.

[0063] A transmission groove 908 is opened inside the left side of the wooden board support 6. A gear rod 909 is rotatably connected between the two sides of the inner wall of the transmission groove 908. The right end of the gear rod 909 penetrates through the transmission groove 908 and is fixedly connected with a slave gasket 910. It should be noted that: the slave gasket 910 and the main gasket 907 are coaxially arranged. When the wooden board is clamped between the main gasket 907 and the slave gasket 910, the slave gasket 910 can drive the wooden board to rotate coaxially with the main gasket 907 to avoid interference; and the slave gasket 910 and the main gasket 907 are clamped at the middle position of the side wall of the wooden board.

[0064] A transmission rack 911 is slidably connected to the inner bottom surface of the transmission groove 908. The top of the transmission rack 911 meshes with the bottom of the gear rod 909. One end of the transmission rack 911 is fixedly connected with a pressing rod 912. One end of the pressing rod 912 penetrates through the transmission groove 908 and is movably inserted on the surface of the support frame 5. It should be noted that: a kidney-shaped groove is opened on the side wall of the support frame 5. The pressing rod 912 is slidably connected inside the kidney-shaped groove, and the kidney-shaped groove has the same length as the adjustment groove 801; when the pressing rod 912 is pressed and drives the transmission rack 911 to move to the limit position, during the meshing process of the transmission rack 911 and the gear rod 909, the gear rod 909 can rotate 180 degrees.

[0065] The other end of the transmission rack 911 is fixedly connected with a positioning rod 913, and a positioning spring 914 is movably sleeved on the surface of the positioning rod 913. It should be noted that: one end of the positioning spring 914 is lapped on the inner wall of the transmission groove 908, and the other end of the positioning spring 914 is lapped on the surface of the adjacent transmission rack 911; when the pressure rod 912 is disengaged from contact with the convex block 917, the positioning spring 914 produces an elastic recovery effect. At this time, under the restriction of the wooden board cushion strip 902, the bottom of the wooden board will not produce a rotating effect, so that the transmission rack 911 and the pressure rod 912 will not reset. When the wooden board is removed from the wooden board bracket 6 after grinding, the positioning spring 914 can drive the transmission rack 911 and the pressure rod 912 to reset.

[0066] U-shaped brackets 915 are fixedly connected to the side walls in the middle of the two support frames 1. An adjusting plate 916 is fixedly connected to the top of the U-shaped bracket 915, and the two adjusting plates 916 respectively correspond to the two spring telescopic rods 904 one by one. It should be noted that: the top of the adjusting plate 916 is slightly lower than the bottom surface of the support frame 5. When the support frame 5 drives the wooden board bracket 6 to move to the middle position between the two support frames 1, the spring telescopic rod 904 extends and abuts against the side wall of the adjusting plate 916. As the wooden board bracket 6 moves, the lower part of the spring telescopic rod 904 moves along the track of the side wall of the adjusting plate 916, and the spring telescopic rod 904 pulls the wooden board cushion strip 902 to move into the movable groove 901. At this time, the wooden board cushion strip 902 releases the support for the wooden board.

[0067] A convex block 917 that cooperates with the pressure rod 912 is fixedly connected to the side wall of the rear support frame 1. It should be noted that: the convex block 917 and the pressure rod 912 are arranged horizontally. When the support frame 5 drives the pressure rod 912 to move to the position of the convex block 917, the pressure rod 912 is pressed and moves into the wooden board bracket 6.

[0068] A transmission groove 918 that cooperates with the guide groove 3 is opened in the middle of the side wall of the support frame 1. Support blocks 919 are symmetrically and fixedly connected to the opposite sides of the two support frames 1. A transmission track 920 that cooperates with the guide wheel rod 4 is rotatably connected between the two support blocks 919 at the same level. One side of the transmission track 920 is movably connected to the inside of the adjacent transmission groove 918. A micro transmission motor 921 is fixedly connected to the bottom of the left support block 919, and the rotating end of the micro transmission motor 921 is fixedly connected to one end of the adjacent transmission track 920.

[0069] In this embodiment, as Figures 1 to 12As shown, a transmission roller is rotatably connected to the middle of the support block 919. The transmission track 920 is movably connected between two transmission rollers at the same level. The rotating end of the micro transmission motor 921 is fixedly connected to the bottom of the adjacent transmission roller. It should be noted that when the micro transmission motor 921 is started to drive the transmission track 920 to run, when the guide wheel rods 4 on both sides of the support frame 5 move to the position of the transmission track 920, the protrusions on the surface of the guide wheel rod 4 are caught into the surface of the transmission track 920, and the support frame 5 is stably conveyed to the right by the transmission track 920.

[0070] In this embodiment, as Figures 1 to 12 shown, the grinding mechanism 10 includes grooves 101. There are four grooves 101, and every two grooves 101 are set as a group. The two groups of grooves 101 are symmetrically arranged on both sides of the top of the wooden board support 6. The inner wall of the groove 101 is provided with an adjustable telescopic rod 102. One end of the adjustable telescopic rod 102 is fixedly connected to the inner wall of the adjacent support frame 5. An L-shaped mounting plate 103 is fixedly connected between one ends of two adjustable telescopic rods 102 at the same level. A sandpaper 104 is fixedly connected to the side wall of the mounting plate. It should be noted that the adjustable telescopic rod 102 is a spring telescopic rod 904 that can be telescopically extended in both directions. When the wooden board presses against the surface of the L-shaped mounting plate 103 during the turning process, the L-shaped mounting plate 103 can move towards the inner wall of the wooden board support 6 to avoid interference.

[0071] In this embodiment, as Figures 1 to 12 shown, the top surface of the L-shaped mounting plate 103 is set as an inclined surface. The distance between the left end of the L-shaped mounting plate 103 and the inner wall of the wooden board support 6 is the same as the length of the groove 101. It should be noted that the length of the groove 101 is the same as the length of the adjustment groove 801. When the adjustment rack 803 moves, it can drive the L-shaped mounting plate 103 to move synchronously. When the top surface of the wooden board is being ground, the sandpaper 104 can grind the side wall of the wooden board synchronously.

[0072] In this embodiment, as Figures 1 to 12 shown, a method for using a surface grinding device for solid wood boards used in customized furniture includes the following steps:

[0073] S1. When using this solid wood board grinding device, first place the solid wood board on the top surfaces of the two wooden board cushion strips 902 inside the wooden board support 6, and then rotate the locking screw 906 to press against the solid wood board to move it, so that the solid wood board is clamped between the main gasket 907 and the secondary gasket 910. Then, insert the guide wheel rods 4 on both sides of the support frame 5 into the guide grooves 3 on the two support frames 1 respectively, so that the bottom of the support frame 5 is lapped on the top surface of the left conveyor 2. At this time, the bottom of the spring telescopic rod 904 is compressed by the top surface of the conveyor 2 and contracts. Then, start the conveyor 2 and the drive motor 12, so that the conveyor 2 conveys the support frame 5 to the right, and at the same time, the two grinding rollers 7 start to rotate counterclockwise;

[0074] S2. When the grinding roller 7 rotates, the main gear 807 on the surface of the grinding roller 7 meshes with the driven gear 809 on the side wall of the support frame 1, causing the driven gear 809 to drive the transmission rod 808 and the half gear 810 to rotate synchronously. When the support frame 5 moves the wooden board bracket 6 and the wooden board to the position of the grinding roller 7, the grinding hairs on the surface of the grinding roller 7 come into contact with the surface of the wooden board for grinding. At this time, the half gear 810 rotates clockwise and meshes with the top surface of the adjusting rack 803, causing the adjusting rack 803 to drive the wooden board bracket 6 to move towards the left side of the inner wall of the support frame 5 through the adjusting rod 802. When the half gear 810 disengages from the adjusting rack 803, the return spring 806 drives the wooden board bracket 6 to move to the right for reset. In this way, the wooden board bracket 6 drives the wooden board to move reciprocally during the slow forward movement at the bottom of the grinding roller 7, and can grind the surface of the wooden board multiple times;

[0075] S3. When the wooden board bracket 6 reciprocates inside the support frame 5, the adjusting telescopic rod 102 and the L-shaped mounting plate 103 fixedly connected to the inner wall of the support frame 5 are misaligned relative to the position of the solid wood board on the wooden board bracket 6, enabling the sandpaper 104 to grind the two sides of the solid wood board synchronously;

[0076] S4. When the top surface of the solid wood board is finished being ground by the left grinding roller 7, the support frame 5 moves to the middle position between the two support frames 1. At this time, the spring telescopic rod 904 extends after being released from the pressing state, and then the micro transmission motor 921 is started to drive the transmission track 920 to rotate, causing the teeth on the side wall of the transmission track 920 to contact the side wall of the guide wheel rod 4. At this time, the two transmission tracks 920 drive the two guide wheel rods 4 and the support frame 5 to be conveyed to the right. When the spring telescopic rod 904 moves to the position of the corresponding adjusting plate 916, the side wall of the lower part of the spring telescopic rod 904 moves along the side wall track of the adjusting plate 916, causing the spring telescopic rod 904 to pull the wooden board cushion strip 902 into the internal of the movable groove 901, and the wooden board cushion strip 902 releases the support for the solid wood board. As the support frame 5 continues to move to the right, at this time, the pressing rod 912 on the side wall of the wooden board bracket 6 moves to the position of the convex block 917, causing one end of the pressing rod 912 to be pressed and drive the transmission rack 911 to translate inside the transmission groove 908. At this time, the transmission rack 911 meshes with the gear rod 909 on the top surface, causing the gear rod 909 to drive the spacer 910, the wooden board and the main spacer 907 to rotate 180 degrees inside the wooden board bracket 6 to turn over the solid wood board;

[0077] S5. When the support frame 5 moves to the top surface of the right conveyor 2, the spring telescopic rod 904 disengages from the adjusting plate 916. At this time, the compression spring 903 presses the wooden board cushion strip 902 to extend from the internal of the movable groove 901 and overlap on the surface of the solid wood board, and then the right grinding roller 7 grinds the surface of the turned-over solid wood board.

Those skilled in the art should understand that the present invention is not limited by the above embodiments, and the above embodiments and the descriptions in the specification are only preferred examples of the present invention, which are not used to limit the present invention.

A method for using a surface grinding device for solid wood boards for customized furniture, characterized in that, Using a real wood board surface grinding device for customized furniture as described in claim 6, the following steps are included: S1. When using this real wood board grinding device, first place the real wood board on the top surfaces of two wooden board cushion strips (902) inside the wooden board support (6), then rotate the locking screw (906) to press against the real wood board to move it, so that the real wood board is clamped between the main gasket (907) and the secondary gasket (910). Then insert the guide wheel rods (4) on both sides of the support frame (5) into the guide grooves (3) on two support frames (1) respectively, so that the bottom of the support frame (5) is lapped on the top surface of the left conveyor (2). At this time, the bottom of the spring telescopic rod (904) is pressed by the top surface of the conveyor (2) to generate contraction. Then start the conveyor (2) and the drive motor (12), so that the conveyor (2) conveys the support frame (5) to the right, and at the same time the two grinding rollers (7) start to rotate counterclockwise; S2. When the grinding roller (7) rotates, the main gear (807) on the surface of the grinding roller (7) meshes with the secondary gear (809) on the side wall of the support frame (1), so that the secondary gear (809) drives the transmission rod (808) and the half gear (810) to rotate synchronously. When the support frame (5) drives the wooden board support (6) and the wooden board to move to the position of the grinding roller (7), the grinding hairs on the surface of the grinding roller (7) contact the surface of the wooden board for grinding. At this time, the half gear (810) rotates clockwise and meshes with the top surface of the adjusting rack (803), so that the adjusting rack (803) drives the wooden board support (6) to move towards the left side of the inner wall of the support frame (5) through the adjusting rod (802). When the half gear (810) disengages from the adjusting rack (803), the return spring (806) drives the wooden board support (6) to move to the right to reset. In this way, the wooden board support (6) drives the wooden board to move back and forth slowly in front of the bottom of the grinding roller (7), and can grind the surface of the wooden board multiple times; S3. When the wooden board support (6) reciprocates inside the support frame (5), the adjusting telescopic rod (102) and the L-shaped mounting plate (103) fixedly connected to the inner wall of the support frame (5) are misaligned relative to the position of the solid wood board on the wooden board support (6), so that the sandpaper (104) polishes both sides of the solid wood board synchronously; S4. When the top surface of the solid wood board is polished by the left grinding roller (7) and finished, the support frame (5) moves to the middle position between the two support frames (1). At this time, the spring telescopic rod (904) elongates after releasing the pressing state, and then the micro transmission motor (921) is started to drive the transmission track (920) to rotate, so that the teeth on the side wall of the transmission track (920) contact the side wall of the guide wheel rod (4). At this time, the two transmission tracks (920) drive the two guide wheel rods (4) and the support frame (5) to be conveyed to the right. When the spring telescopic rod (904) moves to the position of the corresponding adjusting plate (916), the side wall of the lower part of the spring telescopic rod (904) moves along the side wall track of the adjusting plate (916), so that the spring telescopic rod (904) pulls the wooden board cushion strip (902) to move into the movable groove (901). The wooden board cushion strip (902) releases the support for the solid wood board. As the support frame (5) continues to move to the right, at this time, the pressure rod (912) on the side wall of the wooden board support (6) moves to the position of the convex block (917), so that one end of the pressure rod (912) is pressed to drive the transmission rack (911) to translate inside the transmission groove (908). At this time, the gear rod (909) on the top surface of the transmission rack (911) meshes, so that the gear rod (909) drives the spacer (910), the wooden board and the main gasket (907) to rotate 180 degrees inside the wooden board support (6) to turn over the solid wood board; S5. When the support frame (5) moves to the top surface of the right conveyor (2) to the right, the spring telescopic rod (904) releases the contact with the adjusting plate (916). At this time, the compression spring (903) presses the wooden board cushion strip (902) to extend out of the movable groove (901) and lap on the surface of the solid wood board, and then the right grinding roller (7) polishes the surface of the turned-over solid wood board.
