[0002] Wood is a natural organic material that comes from trees and is widely used in many fields such as construction, furniture manufacturing, and handicraft production. Wood polishing is an important step to improve the surface quality and appearance of wood, making the wood surface smoother and brighter and enhancing the beauty of its natural texture;

[0003] Existing wood polishing methods include mechanical polishing and manual polishing. Manual polishing is a method in which workers polish the wood surface by hand-held polishing devices. However, this manual polishing method has low polishing efficiency and high labor intensity for workers. Mechanical polishing is a method in which mechanical equipment clamps the wood and then contacts the wood surface with a polishing wheel to polish the wood surface. However, the mechanical polishing method can only polish one surface of the wood at a time, and the polishing efficiency still has room for improvement. Therefore, it is also necessary to improve the existing polishing devices. Summary of the invention

[0071] See also Figure 1 The rack 1 is provided with a placing table 2 for placing the wood 100. The wood 100 can be placed on the placing table 2 for positioning. For details, please refer to Figure 3 A positioning block 201 is provided at the rear of the placement table 2, and the end of the wood 100 can be positioned by the positioning block 201 so that the wood 100 is located within the polishing range of the polishing mechanism 4 in the first direction X;

[0072] See also Figure 1The clamping mechanism can cooperate with the placement table 2 to clamp the wood 100. The clamping mechanism includes a clamping member and a longitudinal push cylinder 7. The clamping member can be provided with one or multiple clamping members can be provided at intervals along the first direction X. These one or more clamping members are connected by a fixing frame 8. The longitudinal push cylinder 7 is installed on the frame 1. The output rod of the longitudinal push cylinder 7 is vertically downward and connected to the fixing frame 8. When the wood 100 is placed on the placement table 2 and positioned, the longitudinal push cylinder 7 drives the fixing frame 8 and the clamping member to move vertically downward, and finally the clamping member contacts the wood 100 and cooperates with the placement table 2 to clamp the wood 100;

[0073] The two sets of polishing mechanisms 4 are respectively located on both sides of the workpiece placement table 2, and the distances between the two sets of polishing mechanisms 4 and the workpiece placement table 2 in the second direction Y are adjustable. Specifically, the two sets of polishing mechanisms 4 include a polishing wheel 401, a polishing motor 402, a motor seat 403, a push cylinder 404, and a cylinder seat 405; wherein the polishing motor 402 is used to drive the polishing wheel 401 to rotate, so that the polishing wheel 401 is in a working state, and at this time, the polishing wheel 401 can polish the surface of the wood 100 when it contacts the surface of the wood 100; the motor seat 403 is used to carry the polishing motor 402; the push cylinder 404 is used to drive the motor seat 403 to approach or move away from the workpiece placement table 2; the cylinder seat 405 is used to carry the push cylinder 404, and the cylinder seat 405 can be adjusted in height relative to the workpiece placement table 2; the height adjustment method of the cylinder seat 405 is not limited, and the linear position adjustment structure in the prior art can be used to adjust the height of the cylinder seat 405;

[0074] The translation drive mechanism can drive the two sets of polishing mechanisms 4 to reciprocate along the first direction X; Figure 2 The translation drive mechanism includes: a connecting frame 501, a screw rod 504, a translation motor 505, and a guide rod 506, wherein the connecting frame 501 is connected to two cylinder seats 405 at the same time, a transmission nut 502 is provided on the connecting frame 501, and a guide hole 503 is provided on the connecting frame 501; the screw rod 504 is rotatably arranged on the frame 1, the length direction of the screw rod 504 is the same as the first direction X, and the screw rod 504 is connected to the transmission nut 502; the translation motor 505 is used to drive the screw rod 504 to rotate; the guide rod 506 is arranged on the frame 1, the guide rod 506 is parallel to the screw rod 504, and the guide rod 506 is coaxially connected to the guide hole 503;

[0075] When the translation motor 505 is started, the lead screw 504 will start to rotate. When the lead screw 504 rotates, it cooperates with the transmission nut 502 to drive the connecting frame 501 to make a linear motion in the first direction X, thereby driving the polishing mechanism 4 to make a linear motion in the first direction X. By controlling the forward and reverse rotation of the output shaft of the translation motor 505, the polishing mechanism 4 can reciprocate in the first direction X.

[0076] In this embodiment, after the wood 100 is placed on the mounting table 2 and positioned, the wood 100 is fixed by the clamping mechanism and the mounting table 2, and then the distance between the two sets of polishing mechanisms 4 and the mounting table 2 is adjusted so that the two rotating polishing wheels 401 are respectively in contact with two opposite surfaces of the wood 100, and then the translation driving mechanism drives the two sets of polishing wheels 401 to reciprocate along the first direction X to polish the surface of the wood 100. After polishing is completed, the positions of the two sets of polishing mechanisms 4 are adjusted so that the two polishing wheels 401 are separated from the wood 100, and the clamping mechanism releases the wood 100 to complete a polishing operation;

[0077] When the polishing wheel 401 is brought into contact with the surface of the wood 100, the polishing wheel 401 may be brought into contact with only a portion of the surface of the wood 100 in the vertical direction, or may be brought into contact with the entire surface of the wood 100 in the vertical direction; if the polishing wheel 401 is brought into contact with the entire surface of the wood 100 in the vertical direction, the entire surface of the wood 100 can be polished with only one polishing operation; if the polishing wheel 401 is brought into contact with only a portion of the surface of the wood 100 in the vertical direction, after one polishing operation, the height of the polishing wheel 401 relative to the wood 100 is adjusted by adjusting the height of the cylinder seat 405, and another polishing operation is performed, and the entire surface of the wood 100 is polished repeatedly in this way;

[0078] After the surface polishing of the wood 100 is completed, the wood 100 can be removed and the polishing surface can be replaced or a new wood 100 can be placed on the mounting table 2 and the above operation can be repeated.

Figure 4 , the projection of the positioning block 201 in the first direction X is located inside the mounting table 2, so that when the polishing wheel 401 moves in the first direction X, it will not interfere with the mounting table 2 and the positioning block 201, so that the polishing wheel 401 can reciprocate along the first direction X at the initial height to polish the entire surface of the wood 100, thereby improving the polishing efficiency;

[0085] In addition, to improve the clamping stability of the wood 100, please refer to Figure 5 When the width of the wood 100 in the second direction Y is large, the distance between the two clamping seats 3 is increased, so that the clamping range of the clamping member in the second direction Y is increased, so that the wider wood 100 can be clamped more stably; please refer to Figure 6 When the width of the wood 100 in the second direction Y is small, the distance between the two clamping seats 3 is reduced, so that the clamping range of the clamping member in the second direction Y is reduced, so that the narrow wood 100 can be clamped more stably;

[0086] It should be noted that, in order to avoid interference between the movement of the clamping seat 3 and the polishing wheel 401 , the positions of the two clamping seats 3 will not exceed the side wall of the wood 100 in the second direction Y.

The upper part of the inner wall of the second fixing sleeve 1002 is provided with a second transmission part 10021. Fig.11 The second transmission part 10021 is a plurality of transmission protrusion structures arranged on the inner wall of the second fixed sleeve 1002 at intervals along the circumferential direction, and these transmission protrusion structures are only located at the upper part of the inner wall of the first fixed sleeve 1001. The upper end of the transmission shaft 1003 is provided with a second connecting part 10032, and the second connecting part 10032 is a plurality of connecting groove structures arranged on the upper end of the transmission shaft 1003 at intervals along the circumferential direction. When the transmission shaft 1003 moves upward, the connecting groove structure at the upper end of the transmission shaft 1003 can provide the second fixed sleeve 1 002 is engaged, so that the transmission shaft 1003 is connected to the second fixing sleeve 1002. At this time, when the input shaft 606 drives the second fixing sleeve 1002 to rotate, it can also drive the transmission shaft 1003 to rotate, that is, the gear 604 is connected to the power source. When the transmission shaft 1003 moves downward and the second connecting part 10032 is separated from the second transmission part 10021, the rotation of the second fixing sleeve 1002 will not drive the transmission shaft 1003 to rotate. At this time, the connection between the gear 604 and the power source is disconnected;

[0097] In this embodiment, please refer to Fig. 9 When the distance between the two clamping seats 3 needs to be adjusted, the fixed tooth group is separated from the gear 604, the transmission shaft 1003 is located at the upper position, and the second connecting part 10032 is connected to the second transmission part 10021. At this time, the power source is started to drive the gear 604 to rotate to adjust the distance between the two clamping seats 3. After the adjustment is completed, the transmission shaft 1003 is moved to the lower position, the second connecting part 10032 is separated from the second transmission part 10021, and the fixed tooth group is meshed with the gear 604. The final state is as follows Fig.10 shown.

[0098] Through the technical solution of this embodiment, when there is no need to adjust the distance between the two clamping seats 3, the gear 604 can be locked by the locking mechanism, which can avoid accidental rotation of the gear 604 and improve the stability of the two clamping seats 3 in the process of clamping the wood 100; in addition, when the locking mechanism locks the gear 604, the clutch mechanism can disconnect the power source from the gear 604, so that even if the power source is accidentally started, it will not apply rotational force to the gear 604, thereby avoiding wear between the gear 604 and the locking mechanism, and extending the service life of the gear 604 and the locking mechanism.

[0099] Example 4

[0100] This embodiment provides a polishing device for wood processing, which, in addition to the technical solutions of the above embodiments, also optimizes the structure of the adjustment mechanism 6;

[0101] In this embodiment, please refer to Figure 8 , the locking seat 902 has a first inclined surface 9021 on one side away from the gear 604, and the adjustment mechanism 6 further includes a spring 1101 and a linkage frame 1102, specifically, the two ends of the spring 1101 are respectively connected to the locking seat 902 and the side wall of the displacement slot 901;

[0102] The linkage frame 1102 is L-shaped, and the horizontal end of the linkage frame 1102 has a ring sleeve, and the linkage frame 1102 is connected to the outer wall of the transmission shaft 1003 through the ring sleeve. Fig.11 , two limiting rings are provided on the transmission shaft 1003, and the two limiting rings can limit the vertical movement of the linkage frame 1102 relative to the transmission shaft 1003, that is, during the rotation of the transmission shaft 1003, the linkage frame 1102 will not rotate; during the vertical movement of the transmission shaft 1003, the linkage frame 1102 will move vertically, please refer to Figure 8 The vertical end of the linkage frame 1102 is provided with a second inclined surface 11021 that matches the first inclined surface 9021. When the linkage frame 1102 moves downward, it pushes the locking seat 902 toward the gear 604 and deforms the spring 1101.

[0103] See also Fig. 9When the distance between the two clamping seats 3 needs to be adjusted, the pulling force of the spring 1101 on the locking seat 902 is greater than the gravity of the linkage frame 1102 and the transmission shaft 1003. At this time, the locking seat 902 can support the linkage frame 1102 so that the second connecting part 10032 and the second transmission part 10021 can maintain a stable connection. After the adjustment is completed, a vertical downward external force is applied to the linkage frame 1102. At this time, the vertical end of the linkage frame 1102 will push the locking seat 902 toward the direction of the gear 604 and stretch the spring 1101, so that the fixed gear set and the gear 604 can be connected. The second connecting portion 10032 is separated from the second transmission portion 10021; the vertical end of the linkage frame 1102 is located below the second inclined surface 11021 and has an extension section, and the locking seat 902 is located below the first inclined surface 9021 and has a surface parallel to the extension section. After the external force is removed, the elastic force of the spring 1101 enables the locking seat 902 to press the linkage frame 1102 horizontally. In the absence of external force, the linkage frame 1102 will not move vertically. The final state is as follows: Fig.10 As shown;

[0104] In this embodiment, it is only necessary to drive the linkage frame 1102 to move vertically to simultaneously drive the locking mechanism and the clutch mechanism to achieve corresponding functions. The structure is ingenious, the operation is simple, and the consistency of the actions of the locking mechanism and the clutch mechanism is ensured, and the adjustment is efficient.
